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