  Great truck! - 2014 GMC Sierra 1500
  By 65wolf - October 22 - 4:09 am

  Well I have owned this truck for almost 6 months and have had ZERO issues and one recall to check transmission line leaks and none found. My last truck was a 2013 Chevy Silverado and this truck is a far better vehicle! It drives better has a better turning radius and just has a better feel driving it. I have owned numerous other trucks Fords, Dodges (junk) and Toyotas and they do not equal this truck. I see other reviews that do not have good things to say but I really LIKE this truck! I tow a small bass boat and it pulls it great. The gas mileage is better than my 2013 Chevy but I have yet to hit the 22mpg highway. Hope this helps someone looking at this truck!

  AWESOME TRUCK - 2014 GMC Sierra 1500
  By clearwatereq - July 21 - 5:43 pm

  Had my 14 crew cab SLT over a year and 26,000 trouble free miles. Im 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.

  Very satisfied Sierra owner.....exceeding my expectations... - 2014 GMC Sierra 1500
  By mbexx - April 16 - 12:22 am

  Seems to be numerous mediocre reviews of the Sierra/Silverado on here, and I fully respect each one. But I also felt obligated to offer up my experience to date.....one that is been very positive. I shopped all of the light duty V8 4x4 trucks, and can say objectively theyre all good options. What sold the Sierra for me: ride quality. I have none of the vibrations mentioned in other reviews. The Tundra is close, but the road noise is much more pronounced. Interior: Subjective I know, but this 2014 interior is more ergonomic, user friendly, and more upscale than Ram, Tundra, Ford. MPG: I am a consistent 22MPG on highway. Price: Spec for spec, $6K less than others with GMC incentives

  Mileage numbers reasonably accurate - 2014 GMC Sierra 1500
  By papanav - October 15 - 8:18 pm

  As of this writing have 7600 miles on my truck with most of that mileage highway miles. I consistently get 22 mpg and did get 24.8 mpg on a trip to Delaware. I have a tonneau cover which I am sure helps with mileage and I noticed on flat terrain the truck runs in 4 cylinders and 6th a lot, hence good mileage. When I pull my trailer with my compact tractor the mileage drops off considerable because it is working much harder. I get about 12-14 mpg in that configuration. Very smooth running truck, comfortable and good looking.

  GM Got This One Right - 2014 GMC Sierra 1500
  By john178 - October 7 - 7:51 am

  Picked up my 2014 GMC SLT Sierra (Z71) today. It is black with black leather interior and chrome galore- including 6 inch running boards. I also put Line-X in bed of truck. The truck is a head turner for sure. There is additional room in the backseat, improved door seals make this even quieter than the 2011 Chevy Silverado I taded in for the GMC. Ive driven around all day and cannot come to grips with how comfortable the ride is. GM hit a homerun on this newly designed 2014 truck.

  16 month review - 2014 GMC Sierra 1500
  By telson - March 27 - 2:30 am

  Just over 40,000 miles on my 2014 SLT crew. Im 75% freeway driving.A few recalls taken care of, bluetooth issues, and replacement of poor quality OEM tires, that sums up the repairs its needed. The factory headlights are sub par, I replaced the factory bulbs with ZXE units with great results. Im very impressed with this truck overall, its getting an average of 20 MPG on mostly freeway miles. This truck feels like a Lexus compared to the F150 it replaced, very quiet and smooth. Comfy seats, and a nice ride are also welcome. Great truck overall!

  Subtle, but well executed - 2014 GMC Sierra 1500
  By jmred - October 16 - 10:54 am

  Have had 3 fords (last w an ecoboost so spoiled on torque) and only now coming back to GM. Had a silvy that was rock hard in terms of durability... But rock hard plastics in the cab sucked. I came back after creaking and lackluster workmanship in the ford turned me off. Silent cab. Not quiet.. Silent! Wife is actually ok w me adding new pipes! This is a z71, All Terrain, so very nice interior and fitting of a lux car. Outside is all business. Nice, subtle change for gmc; modern look that grows on you and doesnt betray the heritage. 5.3 is much stronger than the old one and you cant feel the v4-v8 switches.

  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).

  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.

  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.
