2014 GMC Sierra 1500 SLT 4dr Crew Cab 5.8 ft. SB (5.3L 8cyl 6A)

Comfortable, secure-feeling pickup. Overall quality feel is pure A-1. Daytime confidence value just can't be higher. Motor is strong, shifting is smooth after about 1000 miles. Tows well without sagging in the back due to trailer tongue weight. Best truck I have owned. But, this truck has a blemish--a dangerous one. In rural areas, the headlamp lighting is awful. There is no lateral light spill to assist turning onto intersecting roads. None. Left turns are the worse. You will be turning into total darkness. The effect is as if you have a burned out left lamp. Going straight, the hi-beam doesn't "reach out and touch" enough. You will need to buy auxiliary lighting.

I have put 30,000 miles on my truck before writing this review. No problems at all! Lots of highway miles, lots of testing on dirt roads/paths. Navigation is fantastic, interior on the new models is hands down the best fit and finish of any truck. Transmission shifts silky smooth (dodge was terrible). Headlights are not the brightest, but I have the fog lamps and use them all the time anyway. 5.3 V8 is great, from the school of thought that a full size pickup should have a V8 ( Sorry ford). Get a Sierra, you will not be disappointed.

I have written a few reviews now and somehow they keep getting taken down. This truck is by far the worst truck I have ever owned. The transmission hunts for gears and bangs and clangs. GM said that's normal. The seat has broken 4 times and has been replaced, still broken. Headlights are a joke and a safety issue when it is wet out. Nothing in the truck works right. GPS cannot find addresses, and that ride, awful. When I hit a bump I get a ping in the rear end. Again, according to GM normal. If you like to drive you don't want this truck. I love looking at this truck but I cannot stand driving it. It's awful, its slow and those gears are some of the worst I have ever experienced.

Transmission problem

Ever since I purchased this truck I have dealt with a transmission that constantly up and down shifts especially at slow speeds. It's as if the computer can't decide what gear the tranny should be in so it keeps switching back and forth between gears. The result is hesitation then clanking as the car accelerates or reduces speed. I have been back to the dealership on multiple occassions and as expected they can't replicate the problem???Ironically anyone I let drive the truck always comes back and says what's up with your transmission. I can't believe I was the only "lucky" guy that purchased a lemon. I wish GMC would at least acknowledge there is an issue!!!!!!

I purchased a dealer lifted new truck ( get everything in writing as dealer told me it would not effect warranty.... Straight up lie) # update 122,000 Miles Truck has had multiple tranny issues multiple trips to multiple dealers, horrible metallic noise from somewhere in the power train... I never though I would have a GM with under 130k be ready for the junk yard. GM has contacted me because of my post on Facebook But aside from warrantying the GM tranny that I paid for at 90k I seriously doubt they will lift a finger to help. I would not recommend a GM truck to anyone who drives a lot or depends on their vehicle for an income At 3k miles wipers went out At 10k radiator was leaking At 40k tranny was shifting funny was told the infamous " unable to duplicate " At 50k Tranny was making horible noise, once again " unable to duplicate" Blue tooth system is always messing up At 55k radiator leaking exact same spot and GM refuses to replace At 75k had tra by checked out again for grinding noise was told no issues At 80k tranny goes belly up and dealer and GM refuse to warrant ( 5k put into a truck that's less than 24 months old) At 85k it's time for my bi monthly radiator replacement, this time I go with an after market At 93k traction control goes out At 98k engine has a bad miss and runs rough Over all nice looking truck with to way to many issues, GM will use any excuse to get out of warrant work and the trucks are just not made

I've had this truck in the shop 3 times for a shift issue with the transmission; it would have been more but I'm just waiting for my lease to expire so I can get a Ram! The transmission slams into gear at low speeds and the transmission won't shift so the RPM hangs around 4000 rpm until I let my foot off the gas.

I have a 2014 GMC Sierra Double Cab 2 wheel drive. I absolutely loved the looks of the truck but I have had nothing but issues since day one. The transmission cannot figure out what gear it needs at slow speeds and when it does it jumps and clunks underneath. I have a problem in the rear of the truck that when I back out of my driveway or hit a bump it clunks and bangs. The steering wheel sticks to the right when coming off the highway. When I took it in for repair they would not fix the problem because the could not get a repeat event. I have had several since then which is a huge safety issue. I have problems with rough idling at lights almost like it wants to stall. I have taken my truck in twice for humming in the rear. The first time I was told that it was normal. I returned it a second time and they replaced the gears in the rear end. I am starting to have the same problems again. My grade braking comes on periodically for about five seconds. I cannot even keep my coffee in the cup holder because of the intense vibration on the highway. So far I still have the same issues with 18,000 miles on the truck. I have tried to trade it in but I cannot get anything for it. I filed a claim with GMC and all I get is its taking some time because we don't have the VIN number. I have given the number twice to them so far and nothing. I will never buy another GMC. My next step is the better business bureau. I have been a GM fan for years but this truck is an absolute mess.

The Edmunds review does a good job of describing the trucks good sides. OK, now for the downsides. The throttle response on this truck is an absolute disgrace. There is a delay before your right foot's motion changes acceleration. That and the transmission's obsession with getting into the highest gear possible makes a sluggish combination during normal driving. A downshift sometimes takes several seconds! If this is all for fuel economy, I could possibly understand, but the economy, so far, isn't much better than the 2005 5.3 Avalanche this truck replaced. Maybe because I'm pushing this truck too hard trying to get it to respond to my right foot... Shoulda got the Ram...
Transmission is HORRIBLE

my 2014 Denali 4x4 crew cab is a head-turner. Looks great, smoothest ride of any truck I've ever owned....However, the transmission is miserable. It's as if it can't decide what gear it supposed to be in at lower speeds. I guess I should have never left Ford

As I stated in my earlier comment, I like this Truck! However, the RUST on the frame rails, cross members, rear axle, body mount brackets (the whole chassis) is totally unacceptable! I am beyond mad at the lack of Corrosion Protection Quality taken . My 2014 Sierra frame has more RUST than the 15 year old GM pickup I traded in for this "new" Sierra. The worst part is there is no way to fix this corrosion, other than the "silent TSB" band-aid @ the dealership! Shame on you GM
please don't buy

I bought this truck brand new and it started running like crap. I traded in my Chevy Silverado for this truck. Worst mistake ever! The transmission trys to find gears and the whole truck vibrates at speeds over 60mph. I took it in to be serviced 3 times and still no fix! I will NEVER buy another GMC again.

I replaced a 120K miles F-150 with my 4Dr SLE 5.3L 5.8Ft. (SLE with 5.3 V8 option not avail in listing.) Gas mileage is better than advertised. I got 26.6 MPG with A/C in August in the South. (Best 50 mile average MPG is now 27.3.) I can send a picture of the indicator for those that do not believe. I was traveling at 65 MPH on the interstate with a +-900Lb load in the bed. The 5.3 engine has great torque and will turn high RPMs if asked. Not as much torque as the larger Hemi of the Dodges I've driven, but way plenty to go along with significantly better gas mileage. I get 16-17 around town in mixed driving and 22-23 on the highway at 75MPH. As of 93,000 miles I still get a 50 mile mpg best of 26.3 with an overall MPG of 17.0. UPDATE: Best 50 mile average now 27.9 Dealer provided free oil changes and tire rotations for the first 24K miles. I have had three recalls for 1) possible seat belt anchor cable damage (my truck had no damage), 2) a software issue, plus 3) a software update for the electric steering. I'm not impressed with the quantity of recalls (more than the total I have ever had in all other cars), but the dealer handled them very well and with utmost priority. UPDATE: I now have a Japanese SUV that also has been a part of three recalls by 38,000 miles, including the Tacata fiasco. My truck still rides very well (after the shock replacement). Just luxurious quiet and comfortable front bucket seating. I also have noticed that I have gotten many more compliments on my truck than for almost any other car I have owned. And that is a lot of vehicles. (I'm old.) Some of them are considered classics now. In 2014 I looked at Chevy, Ford, Ram, Toyota, and Nissan trucks. All the imports had less power, lower MPG, and most of them cost more than my GMC. I previously had a 2005 Ford 4.6L and always hated the 11-13 mpg in town, and best ever highway MPG of about 16 on a 400 mile trip without Air Conditioning (Winter). That vehicle blew factory installed spark plugs out of the head, and had uncomfortable seats with nasty upholstery cloth (work truck). Ford has even designed a special tool to repair threads in their aluminum heads without removing the heads from the engine. The apparently common problem that needed such a solution makes me nervous. At this point I wouldn't consider anything but the GM twins for my next purchase. UPDATE: Now at 93,000 miles my only complaint is still the A/C. The first problem, within the first year, was eventually found to be a loose ground. Sometimes the clutch would engage. Sometimes not. Once found, the dealer fixed it free. It was still in warranty. About a year later, they had to recharge the A/C after a leak was repaired. Another year following, the condenser core was bad and irreparable. That cost about a grand with parts and labor. It shouldn't be hard for GM to make the system durable enough to survive way more than three years. I still like the truck, but don't appreciate the dependability of the A/C. I have gone through most of the major (expensive) maintenance items. I did the first brake replacement at 60K miles and when I got into them, there was still 60-75% of the pads remaining all the way around. I now have something near 5,000 miles towing the 6,000 Lb load, and I am very happy with the brake life. My replacement pads are still in good condition. Shocks were replaced at about 70,000 miles. Second brake service, including new rotors was done at 108,000 miles. Paint is continuing to pit on the hood in no particular area or pattern, while the remainder is still glossy. Lifetime fuel efficiency is still 17.0 (Now 17.1) MPG, including trailer towing. I have discovered in the last couple years that I can achieve 16 - 17 MPG (50 mile average) on the interstate while hauling the trailer if I keep my speed at about 65 MPH. No further A/C issues have occurred. Still a GM truck fan. UPDATED March 2023: I now have 112,000 miles on my 2014 Sierra. My best 50 mile average MPG is now 27.9. Lifetime overall MPG, including several thousand miles towing the 6,000 Lb trailer, is 17.1 MPG. No additional recalls or major issues. Now on the second replacement brake pads and first new rotors. The only issue at this time is continued paint pitting (while overall condition is clear and shiny), and occasional hard shifts when accelerator movement changes abruptly as in heavy traffic. Just got rear-ended for the third time in this truck. I will need a new rear bumper, bumper mounts, and tail gate. The little lady with an active social media presence that was following me will need at least the front two feet of her little sedan replaced. Still a GMC fan!

Well I have owned this truck for almost 6 months and have had ZERO issues and one recall to check transmission line leaks and none found. My last truck was a 2013 Chevy Silverado and this truck is a far better vehicle! It drives better has a better turning radius and just has a better feel driving it. I have owned numerous other trucks Fords, Dodges (junk) and Toyota's and they do not equal this truck. I see other reviews that do not have good things to say but I really LIKE this truck! I tow a small bass boat and it pulls it great. The gas mileage is better than my 2013 Chevy but I have yet to hit the 22mpg highway. Hope this helps someone looking at this truck!

For the most part it's a good truck. But at 37000 miles radiator had to be changed and front brake and rotors along with rear brake rotors and calipers. Headlight are just okay. Don't think this truck would make the long haul over time. Will probably be my last Chevy or GMC. Time to get back into a Toyota. I gave GMC an honest try. I also manage a fleet of Chevy 1500. Very expensive to keep on the road.

Bottom line, if you want to 'see' where you are going, don't buy this truck. This is my third GMC, and it is becoming a bigger disappointment every day. I have pictures to post if I could figure out how to do it.. ps... my ride is an SLE 5.3 double cab... that model is not listed in the choices above

Is GM ever going to hire some who knows how to program an engine/transmission ? I own a 2014 sierra 1500 and have decided I won't put up with the horrible engine and tranny operation any longer.Warranty or not I will have a tune done and it will NOT be anything written by GM. I do know people who have had it done to their trucks,have driven them,and I will do it to mine. How anyone at GM who signs off on these driveline calibrations still has there jobs is beyond me. These people do not know there jobs and need to go. A tuning person with real world knowledge is needed. A laptop, some realistic programming and an hours seat time is literally all that is needed! GM,the public deserves better!
Very satisfied Sierra owner.....exceeding my expectations...

Seems to be numerous mediocre reviews of the Sierra/Silverado on here, and I fully respect each one. But I also felt obligated to offer up my experience to date.....one that is been very positive. I shopped all of the light duty V8 4x4 trucks, and can say objectively they're all good options. What sold the Sierra for me: ride quality. I have none of the vibrations mentioned in other reviews. The Tundra is close, but the road noise is much more pronounced. Interior: Subjective I know, but this 2014 interior is more ergonomic, user friendly, and more upscale than Ram, Tundra, Ford. MPG: I am a consistent 22MPG on highway. Price: Spec for spec, $6K less than others with GMC incentives

I really love my truck, runs really well, shifts great and the interior is awesome. Lots of room, and very quite. I can have a conversation without speaking loudly. It truly rides like a dream but better when weight in the bed. One thing I don't like is the turning radius, in tight spots its difficult to turn. Everyone who rides in it loves it. I really like the look of the vehicle, great styling all around. Had LINEX bed liner put in and ZEIBART in and out. make sure to have everything real clean and remove door panels and wheel wells for good job. Takes time, but I bought it to keep it a long time! Check out for any updates or upgrades available. LOVE THIS BEAUTIFUL TRUCK!!!

6 month update. Gm has not fixed any thing since new. Radio GPS headlights are still awful. 7 Recalls so far. New problems leather coming off seats,look like 50 year old bomber jacket. Dash settings constantly reset, rattles every where,seems dealer can not hear it. Was getting 16 mpg,after fire flash recall dropped to 13-14,dealer says that was expected. (not when I bought it), Tried to trade it in on new Toyota,they would not take it. $50k pos. Advertised as professional grade, the only thing I am getting professional at is taking it to the dealer Update. Got rid of this pile of junk before the first oil change back in April 2014. Got a Nissan truck and have not been happier with a vehicle. Will NEVER purchase GM product again

Have had 3 fords (last w an ecoboost so spoiled on torque) and only now coming back to GM. Had a silvy that was rock hard in terms of durability... But rock hard plastics in the cab sucked. I came back after creaking and lackluster workmanship in the ford turned me off. Silent cab. Not quiet.. Silent! Wife is actually ok w me adding new pipes! This is a z71, All Terrain, so very nice interior and fitting of a lux car. Outside is all business. Nice, subtle change for gmc; modern look that grows on you and doesn't betray the heritage. 5.3 is much stronger than the old one and you can't feel the v4-v8 switches.

I have 54733mi on my 2014 Sierra 1500 with 5.3L V8. I like everything about this truck except the headlights You literally cannot see at night if its raining outside, yes its that bad. I bought a $300 Hid kit and seeing at night is the best ever. If you buy this truck and you plan on driving at night then its imperative that you converted from halogen to Hid to be safe.

GM won't admit, be accountable or responsible and replace or fix these trucks so let's band together and sue them!!I. This truck is a piece of junk. I was a GM loyal customer. This truck and my experience of GM not caring, making excuses and not doing the right thing changed that. I am done with this company and I am telling everyone. The AC high pressure line br!oke 3 times due to a manufacture defect, I paid out of pocket to replace each time. Due to defect this will be an ongoing cost as it will continue to happen. Then major vibration and clunking in the rear end, issues they refused to fix and it came apart and knocked a hole in the rear end in the bottom of the casing. I looked online an found numerous complaints regarding same problem. There was even mention of a possible recall in the future. I told our local GM dealer service department manager about the numerous complaints online and he said, " Not here." There was seatbelt recall and a steering assist recall too. They claim to have high quality vehicles. They used to This truck is a money pit piece of junk and I am mad and very DISAPPOINTED in GM to put it midly. GM needs to step up and do the right thing. But they refuse. Dealership service manager was rude and no help whatsoever. I was told they don't fix things for free and that vehicles are not made the way they used to be, that now the government builds our vehicles. Since this billion dollar company does not care about their customers or the quality of their vehicles boycott them and let's make a stand tiger and make them do the right thing,

This truck is great on the highway - smooth ride even empty, unbelievably quiet, comfortable seats, lots of luxury features. I am coming out of an Infiniti SUV and this thing compares very favorably with it on the highway. I am getting about 19-20 on the highway thanks to the cylinder deactivation, which you can only see indicated on the dash, you never feel it at all. It feels like a Mercedes, everything is solid and tight - hard to believe this is a GM product it seems so well-built. I drive country roads at night, the lights are ok - not horrible not great. Get the fog lights, they help. I run the fog lights all the time.

The truck has been trouble-free, aside from a faultily installed wire in the haptic motor of my "Safety Alert Seat" that has been repaired twice. 2 Scheduled services with oil change/rotation have been free. Gas mileage has been good for a V8 4x4 (about 16 mpg overall). Brakes aren't fussy, though sometimes you have to push hard. Steering feel and handling are what you'd expect from a large truck. Performance from the engine is strong but the transmission upshifts too quickly at times. Interior is very comfortable and improved, seats nicely bolstered - great for long trips. The technology is very easy to use. Road noise is minimal and ride outstanding. Great truck.

Just over 40,000 miles on my 2014 SLT crew. I'm 75% freeway driving.A few recalls taken care of, bluetooth issues, and replacement of poor quality OEM tires, that sums up the repairs it's needed. The factory headlights are sub par, I replaced the factory bulbs with ZXE units with great results. I'm very impressed with this truck overall, it's getting an average of 20 MPG on mostly freeway miles. This truck feels like a Lexus compared to the F150 it replaced, very quiet and smooth. Comfy seats, and a nice ride are also welcome. Great truck overall!

When I first saw this truck it was love at first site. However, after driving it over 5000 miles, I started to hear a hum in the rear end. To make a long story short, the druck has been in the shop for a total of 3 months. The differential has been rebuilt, drive shaft replaced, rebuilt deferential taken out and brand new differential installed, driver seat had to be shimmed, and a total of 3 recalls. You would think that after all of that the problem would have been solved, WRONG, I still have a hum in my rear end and a pain in the other. It is a shame that a billion dollar company like GM won't admit that they made a screw up with at least my Sierra. I can't recommend to anyone.

I was so excited when the 2014 gmc came out. They where a nice change of appearance. Although once you buy one the story changes. The headlights are horrible, very difficult to see at night. The transmission has no clue what is should be doing, shifting when it should not be and not shifting when it should and makes loud noises. Absolutely no FM/AM radio reception, anywhere. I have not yet found a comfortable seat/head rest position. Now that i have this truck i do not look forward to driving it.

I bought mine about one month ago. Nice sexy black truck all the toys. Mile mark 480 noise coming from the rear end. GM tried to say it was the displacement on demand. Turned out to be a bad ring gear. Truck ended up needing a whole new rear end. Mile mark 680 transmission is clinging and clanging under normal driving conditions with decelerating only to be followed by not knowing what gear to select with I put my foot back on the gas. Today it was stuck in 2nd gear for about 8 seconds. Also new today, the truck stalled with a huge bang in the transmission when shifting from R to D. I like the truck a lot when it is parked. Not so much when driving. Buyer beware...

I wrote the review "looks good, drives poor" Here an update with 4000 miles. The truck has continued to be a disappointment. I had to replace bolt rear shocks due to leaks. The drives seat broke, twice. I'm not a huge guy about 160 lbs and the seat keeps breaking. Drivability of this truck is poor, shifts are still very questionable both upshifts and down shifts. On a recent 650 mile highway drive, the truck shifted quite a bit on cruse at 74 mph. Average mpg on trip 17.3 Awful. MPG has declined and I average about 14.8. Compared to my 07 5.3 Silverado its about 3 mpg less. Maybe I got a bad one, but how many bad ones are out

The headlights just don't throw the light far enough down the road on dim and brightness is marginal. High beams are OK at best, about what the dims should be. The side illumination when turning a corner is pretty much non-existent. The rest of the truck is great, comfort, ride, handling performance, etc . The MPG is really great for a truck, keeping it @ 70 or less, I can knock down 23-24 on the highway!

bought new at the springfield, vt. gmc dealership. am very happy with it. initially, I was getting a rattling noise in the muffler/driveshaft area. gmc dealer found it was a loose baffle in the muffler. after exhaust system replacement, the sound is gone and has not returned. I get good mileage. has better options than my last new truck(Silverado). Headlights were insufficient at night when new. Gmc had a service bulletin on this issue. They replaced the bulbs(n/c) . Have been fine since. Had a rhino liner sprayed in. Great investment. Recommend keeping tailgate locked at all times. Periodic rash of theft in the area. Very easy to unhinge and disappear. I currently have 10k for mileage. Although i bought the truck in Vermont..i have a local GMC dealer take care of inspections,oil changes,etc. would i buy another GMC ? Absolutely!! Tried to select the year (2014) but drop down menu will not allow.

This is a beautiful looking truck that everyone stops and stairs. The 50 thousand price tag for a truck that is already rusting at 25k miles and has had the radiator replaced at 11k miles, several recalls, etc. Not worth the money. Stick to the oldie but goodies. Again she is a looker till you look underneath. Don't do it and if you already did such as myself, get rid of it while you can!

Was forced to make GM repurchase under Lemon Law. Had an issue with snow entering the heat ducting causing ice to build up on blower. After multiple service calls dealership decided they could not fix it and told me there was nothing they could do. Living in Michigan made the truck almost impossible to drive in the winter. GM also was no help. Customer solutions person managing my case would not return my calls. In the end forced to sue. Very disappointed. No apologies or any effort from GO to rectify the situation. Have been driving for almost two months now and am a little underwhelmed. Its a smooth ride and the road noise is much improved over my 2007 Silverado but the 4.3 just doesn't seem to be enough for this truck. The mpg on the highway have been about 20 which is ok but the city mpg so far has been in the 9-11 mpg range which is very unsettling considering GMs mpg claims.

I will replace this truck with one just like it. The reliability is outstanding and have not had any issues. Only service has been scheduled maintenance and replaced tires at 61,000 miles. Truck looks great, rides great and on straight highway driving have attained MPG of 24 has been my best.

I purchased my new truck September 2013. I made the mistake of paying for the heated/cooled seat option. Big mistake. In cooling mode hot air blows on rear seat passengers. I was told after a few miles the air will cool off.top. The hot air still blows hot after 75 miles. Since I usually have a person in the back seat that is a waste of money. Also after 75-100 miles it feels like I am sitting on a fist sized rock. Guess what, the dealer reps got in and out of the truck and stated they could not duplicate my complaint. GMC service rep got involved after reading my complaint and I was able to get the seat fixed. I now have 52,335 miles and the seat is much more comfortable. Still unable to use the seat cooling with rear seat passengers. And, the rear seat ventilation duct outlet that is under the driver and front passenger seat has very little air going to the rear seat passengers. I would like to see the same type of rear seat ventilation that my 2003 Chevrolet pickup had. Ducted outlets at rear of console to enhance the comfort of rear seat passengers. Initially I got 21.5 to 22.5 mpg at 68mph. Whick was why I boutght the truck. After a recall I now get 18 if lucky.

My 2014 GMC Sierra has never good mileage. Yes--it's 4 wd and the 5200 motor but the door sticker claimed it would get much better. Well , I have 17000 miles on the truck now and updating my review. The gas mileage is still very poor with about 15-17 highway and 10-11 around town. The thing I hate worst is the seats for they are way too low with no adjustment to go up. Also, hate the location of the window crank handles for they are too low and hard to reach. Yea--I know--crank windows but this is a work truck but has some great options like 4x4, 5200 motor, ac. great radio and nice chrome wheels. Over all a good truck for the money but come on GMC--be fair on the window sticker on the gas mileage!

Have had my 2014 Sierra 1500 Z71 4WD for little over 4 years now. Overall great experience but some set backs. First, exterior styling is awesome, mechanical wise the transmission and engine both run strong, locking rear differential does its job. MPG not bad for power/weight ratio. Major problem I had was driver-side (LH) rear axle seal went bad/leaked with just 9,500 miles on it. My owning experience was further dampened by at least 10 recalls from GM-I understand about small glitches but it left a bad impression. I don't believe that GMC is "professional grade," maybe the premium the customer paid for the brand pro grade-premium. No doubt better quality for American vehicle these days. I do give GM credit for making the truck that holds up to ordinary/average daily use. Daily use of hauling kids and sports gear(s) and moving mulch for d.i.y. house work. As to Apr 2018, I've had the Sierra for 99,645 miles, transmission fluids were changed at 65,000 miles and next change will be at 110,000. I've never had a problem with the auto transmission, it runs strong with smooth/crisp shift points, I've driven the vehicle from central U.S. to West Coast and back. Engine is also strong on the vehicle, I change the oil on avg every 4,500 or 5,000 miles OR every 3 months.

very disappointed in this pickup. transmission down shifts when going at low speeds and try to speed up. the Navigation system has started acting up by adding 1hr 30 minutes to arrival time on and dealers says nothing they can do. just have to live with it. Totally unacceptable but can't get GMC dealers to even try find the problem.

I have RUST on my entire frame (rails, cross members, and all welded bracketry off rails). I noticed this just 3 months after purchasing brand new. Apparently it's not okay for the Rancho shocks used to exhibit pre mature rust (as they were recalled earlier) , but it is okay for GM's truck frames to RUST after 3 months? The TSB is just a band aid. How do you prep and redo a closed box section of frame rail? Why would you use bare uncoated (non galvanized) steel? The coating on a scratch off lottery ticket stays on better than the black wax coating used! Not acceptable General Motors! "Amateur Grade" Sincerely, Disappointed Customer....Update; worst rear vision camera in the industry... worthless at night.

I pretty much have a fully loaded SLT and I used to love my truck. The redesign of the vehicle is what prompted me to buy one and it looks great and handles well. However, since I got it, I've had nothing but problems. I've had it for 2.5 years and have put 37k mile on it. This is what has gone wrong with the vehicle since I got it: 1) AC went out at 18K miles. 2) Visor had to be replaced at 4k miles. 3) Rear passenger seatbelt had to be replaced at 10k miles. 4) Bluetooth disconnects once a song or playlist finishes playing. 5) Trailer break controller gave me problems at 10k miles and had to be replaced. 6) Transmission locks up sometimes. 7) I'm getting 12-13 mpg on the street. 8) Dealer mentioned my catalytic converter was having issues. 9) Dealer mentioned that my engine was misfiring. 10) Front parking sensors had to be replaced 11) Battery went out at 35,700 miles. 12.) Had numerous safety bulletins performed. 13) Airbag sensor had to be replaced. 14) Airbag service light won't go away. 14) Paint job is very delicate; scratches for any little thing. 15) Rotors making noise when I back up even though I'm told my brakes are fine. 16) ABS is faulty; I have to press the break all the way down for the vehicle to stop. Fixed itself temporarily with a very harsh brake, but seems like it's coming back. As you can see, this is not what I expected from my first new pick up truck. I've owned numerous used trucks before and none of them gave me these amount of issues. At this point, I don't know what to do. I love the look and feel of the truck, but I also wanted reliability out of this 50k+ vehicle. I thought about trading this one in for a newer one but again, I question GMC reliability. I also thought about buying an extended warranty to cover me but then I thought why do I have to shell out an extra $2,500 to fix this unreliable truck. GMC needs to do something about this....

I have had my Sierra for about six months. I have not experienced any problems what so ever. If you are easy on the gas and drive sensibly I get from 18 to 20 MPG around town and usually 25 MPG hiway. My best 25 mile average was 32.5 MPG between Houston & Galveston. Very quit ride, better than my Cadillac and just as smooth. I feel very safe and comfortable in my first truck.

First off this review is for my 6.2L not the 5.3l. I came from a 2013 GMC denali . this new 2014 is by far better, Very Quiet, and this new 6.2L is a Real Rocket, I am getting yes AVE 17.8 with mostly City driving about 20 miles per day this is amazing compared to my 2013 denali which got Ave 14.8 City. this 2014 I purchased is a mid year build (6/14) and Built in the Indiana plant, and they have done a great job during assembly, things fit well no noises or Rattles and no problems so far. Turning radius is great, no Radio Reception problems I am not sure yet about the headlamps, they seem to be fine, however I do not like the interior lighting, its all LED and no footwell lighting.

I wrote a few articles now "looks good drives poor" Unfortunately I need to make a third. After GM bought back my 14 z71 and I ordered a Denali, more problems. The steering wheel was off from the factory. If you hold it straight you will crash. It is currently in the shop for a faulty gas pedal. Once again the driver's seat has broken. The backup camera and audio only works when it wants. Drive like whip lash and a throttle response that is poor at best. The 2013 rental Tahoe I currently have drives like a dream compared to this truck. I like the idea of the truck, but the execution is awful. A new truck should not require me to have an outside company tune the computer. Get a F150 Note: this ended up being a gm buyback Lemon and my 15 that I got is the worst vehicle I have ever owned. Take a look at ram or Ford.

Got 2014 Sierra All Terrain in sept 13. Healights are terrible to the point of dangerous. Far too dim. Had to install after market off-road lites. GM would not acknowledge problem. 4 wheel drive would not engage while stuck in snow high range. Engine would not accelerate. Transmission clunks and shifts strangely. Seems to hang up between gears at low speed acceleration and slips. Truck has already been recalled 7times. Now it is leaking ant-freeze and will heed to go back to dealer. Radiator had to be replaced. It will be a Dodge Ram next time. 5-16-17. Got the Ram. Also has terrible headlights.

Strange to read all the horror stories about vibration, clunks, trans slipping. I have a 2014 Sierra V6 WT with the only options of a locking rear differential and a hitch. I crank my windows. Have about 2000 miles on it now. It is quiet, shifts smoothly, rides firm but it is a truck. It is quite powerful if you lay into it, most of the time I don't and it gets 18-19 city. Not sure about hwy yet but indications are it will get the advertised 24 hwy. No rattles or strange noises, actually it is very quiet. I wish it had a better exhaust note. You have to turn down the radio and concentrate to feel it go from V6 to V4 and back. The reg cab lighting could be better.
