  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!

  third truck purchase - 2014 GMC Sierra 1500
  By s thom - November 3 - 11:32 pm

  bought new at the springfield, vt. gmc dealership. am very happy with it. initially, I was getting a rattling noise in the muffler/driveshaft area. gmc dealer found it was a loose baffle in the muffler. after exhaust system replacement, the sound is gone and has not returned. I get good mileage. has better options than my last new truck(Silverado).

  Long term Update - 2014 GMC Sierra 1500
  By qzationsa - December 26 - 6:14 am

  I wrote the review "looks good, drives poor" Here an update with 4000 miles. The truck has continued to be a disappointment. I had to replace bolt rear shocks due to leaks. The drives seat broke, twice. Im not a huge guy about 160 lbs and the seat keeps breaking. Drivability of this truck is poor, shifts are still very questionable both upshifts and down shifts. On a recent 650 mile highway drive, the truck shifted quite a bit on cruse at 74 mph. Average mpg on trip 17.3 Awful. MPG has declined and I average about 14.8. Compared to my 07 5.3 Silverado its about 3 mpg less. Maybe I got a bad one, but how many bad ones are out

  Great Truck - 2014 GMC Sierra 1500
  By lawman1967 - December 10 - 11:41 am

  Ive had my Sierra SLE 4X4 All-Terrain for three months now, though Ive only been driving it for one of those months as it was rear-ended by a Hummer (no frame damage) and in the body shop for a month, then I was away for three weeks of military duty. Still in those 5 weeks of driving Ive put over 8,000 miles on the truck and have a pretty good idea of its capabilities and performance. The truck remains an absolute joy to drive, no squeaks, supremely comfortable seats and quiet ride. Fuel economy up to 24 MPG at 75 MPH which is OUTSTANDING for a V8 4X4.

  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.

  Nice looks, but quite a step backwards... - 2014 GMC Sierra 1500
  By csviper - November 6 - 3:10 am

  Just purchased my new 2014 GMC Sierra with all the bells and whistles just a step below a Denali and wow, this thing looks nice, but really it is very similar to a truck I had many years ago. There are a few pieces of technology that are a nice upgrade (when they work), but they also skimped on some of the basics. As shown below some of the items that were standard items years ago are not even options today. The iPhone USB interface is hit or miss with IOS 8.0.2. Sometimes when making/receiving calls you get hand free, sometimes you have to use the phone itself. Also the heads up display is just a red flashing light, no information shown. Maybe next year...

  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.

  Second 2014 Sierra - 2014 GMC Sierra 1500
  By qzationsa - September 22 - 9:39 am

  I wrote a few articles now "looks good drives poor" Unfortunately I need to make a third. After GM bought back my 14 z71 and I ordered a Denali, more problems. The steering wheel was off from the factory. If you hold it straight you will crash. It is currently in the shop for a faulty gas pedal. Once again the drivers seat has broken. The backup camera and audio only works when it wants. Drive like whip lash and a throttle response that is poor at best. The 2013 rental Tahoe I currently have drives like a dream compared to this truck. I like the idea of the truck, but the execution is awful. A new truck should not require me to have an outside company tune the computer. Get a F15

  Not a happy GMC owner - 2014 GMC Sierra 1500
  By silverct - June 13 - 5:38 pm

  Bottom line, if you want to see where you are going, dont buy this truck. This is my third GMC, and it is becoming a bigger disappointment every day. I have pictures to post if I could figure out how to do it.. ps... my ride is an SLE 5.3 double cab... that model is not listed in the choices above

  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!
