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 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 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.

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.

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
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 don't have any of these problems!

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!

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.

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.

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 Really Like This Truck

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.

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.

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!

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

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

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!

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.

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.

FRAME RUST EVERYWHERE (Bumper to Bumper)

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.

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.

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,

Had my 14 crew cab SLT over a year and 26,000 trouble free miles. I'm getting a steady 21 mpg highway. Truck is extremely smooth and quiet. I traded in a 2012 Ram and this GMC feels more refined with better on road performance. Great truck overall.

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 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.

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....

28,000 noise from the front left wheel at low speeds. navigation is inconsistent. I use my phone before the on board nav. Don't waste money on this feature. Very rough shifting. Braking is rough. A/C went out at 5,100. I researched this problem and it is a national epidemic for the vehicle. It is unfortunate that GMC would not take ownership of the problem. Instead the owner incurs the cost. For future GMC owners I would highly suggest researching other vehicles. This is my third CHEVrolet/ GMC and based on this vehicle, it will be my last. Still having problems. Misfire in number 7 led to cool pack replacment. Automatic start stopped working.

Just purchased my new 2014 GMC Sierra with all the bells and whistles just a step below a Denali and wow, this thing looks nice, but really it is very similar to a truck I had many years ago. There are a few pieces of technology that are a nice upgrade (when they work), but they also skimped on some of the basics. As shown below some of the items that were standard items years ago are not even options today. The iPhone USB interface is hit or miss with IOS 8.0.2. Sometimes when making/receiving calls you get hand free, sometimes you have to use the phone itself. Also the heads up display is just a red flashing light, no information shown. Maybe next year...

I think you owe us an apology. You seemed to think the 2014 GMC sierra was a decent truck. I would like to let you in on the problems that most of the people are having with these trucks. Many rattles inside truck,FM radio can't hold a strong signal even sitting still, I have the Bose system and all I get is very nice sounding static.(think it is on purpose to make us buy XM) The headlights are so dull we are afraid to drive at night as they only light about 3-4 car lengths ahead even on high beam (no actual high beam light just a filter that moves to let out more light). Rear shocks that leak and make noises. Water leaks to the interior. Power rear sliding windows that the cables break and

Great truck, quiet, versatile, and decent fuel economy for a truck. Best truck I've owned to date. I'm the second owner of this truck, and at 105,xxx miles I've only had one issue, the condenser had a leak and was replaced. I now have ~ 113,000 miles, replaced the front brake pads and all tires. This truck is solid. I had to replace the rear driver side power door lock since my last update. The truck know has ~125,xxx miles. Just recently had some paint flake off my driver side rear door as well . starting to see some paint bubbling on the rocker panels. At ~ 134,xxx miles I am also starting to see some rust in the fender wells of the box. no mechanical issues since last update.

Upgraded from 08 Denali and it was a big mistake. Old denali all will drive 6.2 engine mileage 13.9mpg New SLT 2 weel drive 5.3 engine mileage 15mpg at most with their promises on paper 16-24 Headlights are total garbage and dangerous to drive in dark situations, and finally the metallic paint looks like factory forgot to mix the paint before and just painted the way it is. If you have same rtuck and your opinion is diffirent than mine let me know.

PILE OF JUNK is putting mildly. The reason I waited until know before writing a review was because I wanted people to get an idea of the long term reliability rather than the short term review. I purchased the truck new in 2014. At around 45,000 miles the radiator went. Shortly after that the A/C went. Then the clincher was the transmission went at 110,000 miles. This truck was babied from day one. I never used it to plow or carry heavy loads. When I tried to contact GMC regarding these matters I didn't even get a call back. The gentleman who replaced my transmission (not the dealer) said that this truck is really no more than a truck shell on a SUV chassis. After driving it for the past 4 years I think he was right. I now have suspension issues and noises I can't even identify. Tomorrow is going to be a great day since I'm trading the PILE OF JUNK in for a 2019 Dodge Ram.I have been now driving the RAM for one year and absolutely love it

I have owned my GMC Sierra Denali for around 4 years. I have to say, it has been in the shop just a smidgen outside of warranty two times and has honestly been a tremendous disappointment. GMC stepped in after some social media prodding and covered the cost of one repair since it was a known issue (ac lines rubbing and rupturing) but rather than pay for a recall and install a simple bracket they just roll the dice. I also had to pay the $200 diagnostics at the dealership... ALSO, my trailer brake system malfunctioned and I have had multiple electronic issues from the power stearing dying mid trip to the back up camera freaking out. Now, this went away after the trailer brake control that I had never used was replaced but it wasn't covered. It was $800 all said and done. The door seals on the driver side door are misaligned and have been to the dealership twice to no resolution. It is more noisy than a blow dryer in my ear on the highway. Also, this model was rushed out not featuring the 3G, NFC charger, or other features that were advertised. The 2015 did however add them, along with the AC bracket. Furthermore the resale value is trash. I admit, I bought a Denali... I know it is an overpriced SLT with a stamp that makes it cost more, but still.. The fair trade in is laughable. I will drive it as long as it functions as a result, and have bought my last truck form GMC (my last sierra started fouling plugs every week with oil getting in, I should not have given them a second chance.

I bought my truck two years ago with 150,000 miles, I'm almost at 200,000 now and it still runs great. I haven't had many issues with it especially considering the mileage. I only had to take it to the dealer once to get the A/C fixed but other then that the only complaints I would have are the occasional check engine light for an O2 sensor that always ends up going away and it does have a little shake at highway speeds but its nothing that really bother me. When I first bought the truck the headlights were AWFUL but after I replaced the halogen bulbs with better ones I haven't had any visibility issues. I have no regrets buying this truck and would definitely recommend it.

Rust, water and break dust...

Beautiful luxo Blue color. Really nice looking truck. Loaded to the moon. Lots of storage and a lock box under the console. Decent height... But does everything work? No. No it doesnt. I had it a week and the 3rd break light was cracked and leaking water. Read up on it... common problem. Noticed the paint pealing on the bottom of the front passenger door. Looked that up... common in vehicles manufactured in Fort Wayne. Of course that's the sticker in my drivers door. Can we talk about the excessive brake dust? To the point where there's so much heat coming from the brakes that my custom rims are peeling... Alsowhen applying the brakes on the highway there's shaking coming from the rear. The AC doesnt work anymore. Went on a highway ride, about an hour and a half and anything that touched the lower half of the truck...chipped the paint. It looks like it was sand blasted. The threads on the steering wheel are coming loose. The exhaust rattles bad when going from 20mph to 30 mph. Frame is rusty. There are rust spots in the wheel wells. I haven't looked into this yet but I currently smell antifreeze. I still have my 2001 Chevrolet Silverado 2500hd and it doesnt have any of these issues. She has a little bit of surface rust. I wish I rebuilt my 2500hd instead of buying this GMC. I got ripped off for sure. Total lemon. Save yourself the trouble and steer clear.

Only concerns are long wheelbase when it comes to parking. That's my only complaint. Mine has 6.2 aluminum engine which is not listed in the options for this review with aftermarket Borla cat-back exhaust system. Enjoyed the engine brake feature. Did not really need to trade up, however my wife pushed me into it. Now I have an '19 equivalent (plus) model and am not real happy with it. Should not have traded up.
