  2014 Sierra Frame Rust - 2014 GMC Sierra 1500
  By 2014sierra - May 24 - 6:13 pm

  I have my 2014 Sierra now for six months, and the frame rails have RUST all over them! The black wax coating GM used is peeling right off! There is a TSB (technical service bulletin) out there for the dealership to repair. These rails are bare uncoated metal. There are rust areas starting all over the rails, so unless they strip off wax over 100 percent of frame, and redo, the spot fix the TSB describes is useless! Why would you use metal deemed Uncoated/Unexposed for a truck frame? $$$$ How did these frames pass corrosion testing / validation?... Very disappointed GM!

  Great truck - 2014 GMC Sierra 1500
  By texasenior - March 28 - 11:15 am

  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.

  2014 Sierra Chassis components (RUST everywhere!!!) - 2014 GMC Sierra 1500
  By 2014sierra - May 28 - 1:01 am

  As I stated in my earlier comment, I like this Truck! However, the RUST on the frame rails, cross members, rear axle, body mount brackets (the whole chassis) is totally unacceptable! I am beyond mad at the lack of Corrosion Protection Quality taken . My 2014 Sierra frame has more RUST than the 15 year old GM pickup I traded in for this "new" Sierra. The worst part is there is no way to fix this corrosion, other than the "silent TSB" band-aid @ the dealership! Shame on you GM

  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.

  Highway Cruiser - 2014 GMC Sierra 1500
  By bigw2014 - May 8 - 5:04 pm

  This truck is great on the highway - smooth ride even empty, unbelievably quiet, comfortable seats, lots of luxury features. I am coming out of an Infiniti SUV and this thing compares very favorably with it on the highway. I am getting about 19-20 on the highway thanks to the cylinder deactivation, which you can only see indicated on the dash, you never feel it at all. It feels like a Mercedes, everything is solid and tight - hard to believe this is a GM product it seems so well-built. I drive country roads at night, the lights are ok - not horrible not great. Get the fog lights, they help. I run the fog lights all the time.

  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.

  Love this 6.2l slt, this is a 6.2L not 5.3 - 2014 GMC Sierra 1500
  By thatblacktruck - May 23 - 10:24 pm

  First off this review is for my 6.2L not the 5.3l. I came from a 2013 GMC denali . this new 2014 is by far better, Very Quiet, and this new 6.2L is a Real Rocket, I am getting yes AVE 17.8 with mostly City driving about 20 miles per day this is amazing compared to my 2013 denali which got Ave 14.8 City. this 2014 I purchased is a mid year build (6/14) and Built in the Indiana plant, and they have done a great job during assembly, things fit well no noises or Rattles and no problems so far. Turning radius is great, no Radio Reception problems I am not sure yet about the headlamps, they seem to be fine, however I do not like the interior lighting, its all LED and no footwell lighting.
