2014 Sierra Denali

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

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.

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.

Got Me A Lemon!

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....

Great truck

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.

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.
