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.

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.

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 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 Faulty

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.

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!

Nice truck, but the driveability is questionable

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
