  Its fine - 2014 GMC Sierra 1500
  By elcar1 - October 12 - 2:24 pm

  Strange to read all the horror stories about vibration, clunks, trans slipping. I have a 2014 Sierra V6 WT with the only options of a locking rear differential and a hitch. I crank my windows. Have about 2000 miles on it now. It is quiet, shifts smoothly, rides firm but it is a truck. It is quite powerful if you lay into it, most of the time I dont and it gets 18-19 city. Not sure about hwy yet but indications are it will get the advertised 24 hwy. No rattles or strange noises, actually it is very quiet. I wish it had a better exhaust note. You have to turn down the radio and concentrate to feel it go from V6 to V4 and back. The reg cab lighting could be better.

  Nice truck, but the driveability is questionable - 2014 GMC Sierra 1500
  By jgedde - November 5 - 3:49 am

  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 foots motion changes acceleration. That and the transmissions 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, isnt much better than the 2005 5.3 Avalanche this truck replaced. Maybe because Im pushing this truck too hard trying to get it to respond to my right foot... Shoulda got the Ram...

  2014 Sierra Denali - 2014 GMC Sierra 1500

  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 cant get GMC dealers to even try find the problem.

  Impressed - 2014 GMC Sierra 1500
  By lawman1967 - December 4 - 9:42 pm

  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. Ive only had it for 1000 miles so cant 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.

  Dangerous headlights - 2014 GMC Sierra 1500
  By larry_rymal - November 18 - 3:59 pm

  Comfortable, secure-feeling pickup. Overall quality feel is pure A-1. Daytime confidence value just cant 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 doesnt "reach out and touch" enough. You will need to buy auxiliary lighting.

  poor gas milage - 2014 GMC Sierra 1500
  By cabo3 - October 3 - 11:25 am

  My 2014 GMC Sierra has never got more than 15 mpg even on high way driving. Yes--its 4 wd and the 5200 motor but the door sticker claimed it would get much better. I talked to the dealer and they blame ethanol gas --poor quality gas ect and ect. I have bought gm trucks for over 50 years and this will be my last. My suggestion to anyone looking to buy GM trucks is to make the dealer fill the truck with gas and test it yourself BEFORE you buy. GM lost my business and my respect! My dad used to say there are two things men lie about --women and gas milage but this report is accurate.

  2014Sierra Slt 4x4 - 2014 GMC Sierra 1500
  By dave572 - May 13 - 9:47 am

  I purchased my new truck September 2013. I made the mistake of paying for the heated/cooled seat option. Big mistake. In cooling mode hot air blows on rear seat passengers. I was told after a few miles the air will cool off.top. The hot air still blows hot after 75 miles. Since I usually have a person in the back seat that is a waste of money. Also after 75-100 miles it feels like I am sitting on a fist sized rock. Guess what, the dealer reps got in and out of the truck and stated they could not duplicate my complaint. Initially I got 21.5 to 22.5 mpg at 68mph. Whick was why I boutght the truck. After a recall I now get 18 if lucky. I am looking to trade it off for a Ford.

  4.3l crew cab SLE - 2014 GMC Sierra 1500
  By gary1965 - September 11 - 8:25 am

  Have been driving for almost two months now and am a little underwhelmed. Its a smooth ride and the road noise is much improved over my 2007 Silverado but the 4.3 just doesnt seem to be enough for this truck. The mpg on the highway have been about 20 which is ok but the city mpg so far has been in the 9-11 mpg range which is very unsettling considering GMs mpg claims.
