  Dont do it! Bad truck - 2014 GMC Sierra 1500
  By qzationsa - November 14 - 2:50 pm

  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 thats 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 dont want this truck. I love looking at this truck but I cannot stand driving it. Its awful, its slow and those gears are some of the worst I have ever experienced.

  Worst truck ever owned in 40 years - 2014 GMC Sierra 1500
  By mad1980 - May 12 - 6:41 pm

  6 month update. Gm has not fixed any thing since new. Radio GPS headlights are still awfull. 5 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

  2014 GMC Sierra All terrain SLT - 2014 GMC Sierra 1500

  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 cant 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

  Transmission problem - 2014 GMC Sierra 1500
  By mb1951 - November 14 - 9:24 am

  Ever since I purchased this truck I have dealt with a transmission that constantly up and down shifts especially at slow speeds. Its as if the computer cant 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 cant replicate the problem???Ironically anyone I let drive the truck always comes back and says whats up with your transmission. I cant believe I was the only "lucky" guy that purchased a lemon. I wish GMC would at least acknowledge there is an issue!!!!!!

  REALLY!!! DONT DO IT. DEALERS TRYING TO GET RID OF OR SOMETHING!!!!!!!!CRAP!!!!!!!! - 2014 GMC Sierra 1500
  By tinasfinest - December 20 - 1:02 am

  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. Dont do it and if you already did such as myself, get rid of it while you can!

  2014 Sierra Impression - 2014 GMC Sierra 1500
  By tomcat25 - May 26 - 9:15 pm

  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 wont 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!
