Truck is a mess

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.

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!

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!

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!!!

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.

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.

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!

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.
Love this 6.2l slt, this is a 6.2L not 5.3

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.

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.

2014 GMC Sierra 1500 SLE 4dr Double Cab 4WD SB (4.3L 6cyl 6A)
5 of 7 people found this review helpful
Traded Mercedes C300 and a Ram 1500 Hemi, and traded both on the Sierra. Mine is an SLE Doublecab with the All-Terrain package and 5.3 V8. I've only had it for 1000 miles so can't really comment on reliability, but truck is very solid going down the road, whisper quiet, smooth, luxurious and just a joy to drive. Its actually more comfortable than the 2011 Mercedes was. The 8" touchscreen stereo with Bose speakers (not listed on sticker or GMC site for SLE, but came with my All-Terrain) sounds great, but the bluetooth and USB connections to my iPhone 5s are a bit flakey. No NAV in my truck, but OnStar works well. Drove 400 miles yesterday, heated bucket seats very comfortable.
Better than expected

First off, there was no pull-down selection for my particular truck, which is an SLE trim, 4x4 double cab with the 5.3 liter V8, so I selected SLT, which is actually close in my case as my truck has the All-Terrain package that includes most of the SLT upgrades (except the leather seats). While cloth, the seats in the All-Terrain SLE are buckets with a great seat heater feature that allows heating the entire seat, or just the back which I love on very long drives. This truck is very comfortable, with a smooth and quiet ride and excellent (for a truck) handling. Steering actually has pretty good feel and the truck corners quite flat. The seats as mentioned above are heated and are very comfortable, with firm padding that holds up well on long drives. The steering is perfectly weighted, though like in all GM full-sized pickups I've ever driven, the steering wheel is an inch or so off-center (just they're design). I thought this would bother me, but honestly it doesn't. Fuel economy tops 20 MPG if I keep speed under 75, but at 85 it drops to about 18 MPG and in town about 15 MPG, with my average over 35,500 miles at 16.2 MPG. I have had no issues whatsoever with this truck. Thus far I've changed oil a few times, wiper blades once and thats it. Everything still looks and feels like new, which is more than I can say about the vast majority of vehicles I've owned over the last 30 years. Highly recommended.

Being a truck, gas mileage is great. Pulls my boat with ease and has power to spare. The color (blue) is beautiful and interior seating (with leather) is very comfortable. Easy to access all necessary controls, and even has adjustable pedals which are linked to the memory seats, mirrors, etc. Now being 70, I am able to provide all my own maintenance and vehicle care. Have owned over 80 vehicles and have owned mostly GM products the past 12 years. This truck has not disappointed me at all! Overall I am fully pleased with my truck and do not over expect what is not possible. My dealership(Jim Ellis) Buick/GMC Mall of GA has always been a great place of service! Having owned and driven this truck since 2017 I have been completely satisfied. Dealership support is excellent and no problems ever. I would purchase a vehicle from them again if needed.... As a mechanic I do all my own maintenance and this vehicle is very easy to work on. I LOVE MY GMC~~

I've had my Sierra SLE 4X4 All-Terrain for three months now, though I've only been driving it for one of those months as it was rear-ended by a Hummer (no frame damage) and in the body shop for a month, then I was away for three weeks of military duty. Still in those 5 weeks of driving I've put over 8,000 miles on the truck and have a pretty good idea of its capabilities and performance. The truck remains an absolute joy to drive, no squeaks, supremely comfortable seats and quiet ride. Fuel economy up to 24 MPG at 75 MPH which is OUTSTANDING for a V8 4X4.

I bought my 2014 GMC Sierra Z71 double cab 4wd 5.3L new in October of 2014. It had come off the line in September. Since then I have noticed that there are numerous rust spots on the frame. Everywhere there are edges, welds, holes, brackets. etc. I don't care for this. As of this date 11/15/2018 the vehicle only has 21,220 miles on it. I run this through the car wash at least twice a month. I bought a new 2001 and when I sold it in 2014, it did not have these rust spots on the frame. Don't know what effect this is going to have down the road, but I worry about towing a trailer like this. I wonder how the brake lines will hold up. Also the projector headlights are terrible in bad weather. With no high beam, the lights are almost useless. Have to drive with fog lights on all the time. UPDATE: The dealer replaced the headlight bulbs with upgrade bulbs and realigned them. MUCH BETTER. Also, dealer applied special coating to the frame and rusted brackets. Looks better than new. this was done in 2018. As of 2020 frame still looks like new. Vehicle now has 28,992 miles on it. UPDATE MAY 2021: Frame stills looks great. Truck has given me NO problems of any kind. Milage is 30,340. Update 11/2022. Truck has been great. No further rust issues once fixed. No issues at all. Truck now has 35,400 miles on it. Runs and looks great. Get lots of positive comments on the emerald green color. Glad I bought it. Update 06/05/2024 Truck now has 41,124 miles on it. Runs super. No problems there, however developed water leaks from the high mount stoplight and sirus rubber roof antenna. Stained the interior inside roof all across the back, and had water actually dripping on me from the upper console. Have ten year extended warranty, but none of this was covered by it. Cost over $2,000 to repair. Not happy with this.

I have had my GMC Sierra for 2.5 years. Overall I have been pleased with this truck. The truck has a smooth ride and is a pleasure to drive on long trips. My only gripe up until recently is the poor visibility of the headlights. Six weeks ago I had an accident with a deer which caused damage to the grill and a condenser located behind the grill which made the vehicle inoperable. I went to my local body shop where the parts were ordered. A day later the body shop informed me that the condenser was back ordered and according to the GMC parts dealer it was on national back order. I waited a week at which time the body shop informed me that the GMC dealer could not give them any time frame on when the back ordered part would be available. I then contacted the GMC dealer where I purchased the vehicle and had it serviced regularly to inquire about the back ordered part. The parts department advised me that the condenser was on national back order and they had no idea when it might be available. I contacted GMC directly and was told they had no information. So after six weeks of frustration and no help from GMC my truck sits in the drive way as I continue to wait for some kind of response from GMC. My family and I have been long time owners of several Chevrolet and GMC vehicles. this will be my last GM vehicle. As soon as my lease ends this October I will be looking to purchase a Ram or Ford Truck.

The truck has been great! I purchased with 29k miles on it and I have put 20k on it from a 50.1 mile trip to work everyday. The truck rides and drives great. With the 6 cylinder engine I have been getting an average of 20.2 mpg. Not the greatest but I believe it's better than the same truck with the 5.3 motor. I did my research and I thought, do I really want a full-size pick-up with a 6 cylinder engine/ Through the research it can tow the same amount as the 5.3L but at a cheaper price initially for than the 5.3L, plus I don't tow a lot. With that being said; the smaller engine theoretically should have cheaper maintenance costs and being the base model with the smaller rims the tires are cheaper too. This exact model definitely seemed the biggest bang for my buck. I still have not purchased tires because the tread is still good and it did well in the 4 ft. snow storm. The only money I have put into it are brakes, rotors and a headlight unit upgrade for $365 that I installed myself as well as running boards that weren't present at the time of buying the truck.

95k miles on the truck, so far 3 radiators ( same issue all 3 times leaking at seam between radiator and endcap, no warranty coverage, thanks GM!). Also 1 A/C condenser also no warranty coverage! Truck rides good and is quite inside but reliability is awful compared to my three prior half ton GM trucks. Headlights are also awful especially when it is raining. I will be selling truck ASAP and going to another brand would not recommend

Beware of undercarriage corrosion if you live where roads are salted. My truck spent 5 years in Vermont, has a good history of regular services and has been kept clean. It still looks great, but the frame and most of the underside look like unprotected metal that has spent a few years in the sea. There was little/no factory protection. It will be dangerous in a few years. The dealer applied some rust preventative per a TSB but it's already failed. I've basically been told to "live with it" by the dealer and the zone rep. I'll never buy another GM product.

I like this truck a lot and I've tried them all, starting with a '87 Nissan, a '98 Ford, '00 Toyota Tacoma, a '04 chevy silverado, and '06 dodge ram (now a different co? What gives?) and this GMC is a powerful, comfortable, and reliable steel safety cage of a truck - we have an ACTUAL horse farm, tow REAL horses and tractors, and I live in SF, so I go out to Petaluma and back, three four times a week, up the grade to the GG Bridge in traffic, driving around the streets of SF in a truck too big to live here. So. To say this is hard working truck is putting it lightly. This is the best truck I've had, mostly because all truck companies make huge advances every year. 29,000 miles in, I'm having some power loss on the hills of SF, a reluctance to go from gear to gear as traffic allows. Not real problems, mind you, but a general sense that I'm headed into the realm of transmission problems (hardly ever the actually transmission but the transfer cases and whatnot). My problem is something that can generally be rectified with a tune up, but I came on here to look at other folks issues with their 2014 sierras, just in case there was an issue others knew about that I should have checked out. Turns out I'm probably better off on the web boards. The reviews here are iffy. I'm surprised at the number of reviews details folks' issues with the Nav System and the headlights. You know you can change those out, right? Doesn't really affect the truck's performance. Obnoxious, but then, I'm equally surprised by the amount of folks' thinking they have problems with the transmission or the engine being hesitant at lower speeds - it occurs to me that there are more people in big trucks who aren't really knowledgeable about how to drive them. So, I write all this to beg those of you who are looking at trucks to ignore warnings about the engine or transmission being weak or unreliable or the front end being wonky - and remind potential truck buyers that opinions are [non-permissible content removed], everybody has one. I highly doubt anyone who was looking for a hard working truck and bought this one has anything bad to say about the 2014 GMC Sierra. But, if you were looking for a flashy fancy truck, you're right, probably should have stuck with the Ford.

Do not buy a GMG. My husband and I have purchased for GMC’s and each time the problems we encountered we thought was something we had done. The most recent a 2014 has had nothing but problems. One driver vehicle and maintenance regularly, yet it has been nothing but a problem. I strongly advised against purchasing this vehicle unless you’re just Going for a cosmetic appearance. Yes they are the prettiest trucks in my opinion but the transmission is faulty and now the engine. Again, this is our third no actually are four brand new GMC never will I ever purchased another GMC truck. Talk to your mechanic or a mechanic before you purchase one of these vehicles

I had certain needs" and certain "wants" when I went looking for a truck in 2014. My GMC Sierra 1500 met then all plus gave me some nice extras that I didn't even know were available. As I'm a big guy (6'4" and 265 lb.) I needed a vehicle with legroom. This had it aplenty. Also had programmable (2) settings to return the seats to where I wanted after someone had moved them. Discovering heated AND air-conditioned seats (leather) was a nice surprise. Indirect lighting in the truck bed was, as well. A 120VAC outlet for household gadgets was also a very pleasant find. One of my "needs" was power folding (along with adjustable) mirrors as I couldn't get this big baby into my garage without folding the mirrors and it was a pain to have to get out and walk around to do this on my previous truck. After 10 years with this vehicle that only thing I was disappointed in was that the OnStar feature was not upgradeable from it's 2G to 5G so I lost the "friendly OnStar folks" to ask where the closest McDonald's is or the closest sporting goods store, etc. The GPS still functions but it has to be programmed manually. Gas mileage is pretty decent and it even runs fine on the "low-grade" 82 octane "ElCheapo" fuel available at some stations. In short I still love my truck!
