Overview & Reviews

The 2007 GMC Sierra 1500 is all-new, from the tires to the roof. Key improvements in cabin trim, build quality, safety features and towing capacity make the Sierra 1500 an odds-on favorite in the full-size pickup class.

• Refined and very quiet ride even with heavy-duty towing package, excellent fit and finish inside, seats are comfortable for long drives, comprehensive list of safety equipment.

• Four-speed transmission sometimes blunts performance, larger turning circle than most rivals, hard door armrests.

  A truck is a truck - 2007 GMC Sierra 1500
  By Gregs Work Truck - March 8 - 9:13 pm

  We purchased this truck for the sole purpose of hauling things. We chose the regular cab, 8ft bed 4.3l automatic work truck. We have rental property and we decided we needed a basic truck with lots of bed space. Our GMC does the job very well. We load lots of stuff in the back and doesnt strain, not one bit. Sheets of plywood and drywall fit perfectly. I am not a fan of trucks, so I dont get excited driving it. The flip down covers for the power ports broke and were replaced. The rubber stops for the gas cover broke and were replaced. All else is good. Its a truck. The airbag light comes on and shuts off the engine. The dealer updated the software and it hasnt happened again.

  Almost perfect - 2007 GMC Sierra 1500
  By WORK TRUCK - February 7 - 5:33 am

  My only complaint with this truck is the transmission. The transmission does not down shift right when you make low speed turns. I have gotten as high as 21 mpg on the highway with a few mods. I have installed cold air, programmer, and exhaust. My daily driving average is about 16 1/2 mpg.

  Flat spot on crankshaft - 2007 GMC Sierra 1500
  By L. Gebhardt - January 18 - 9:23 pm

  Gmc decided to fix enginne instead of replacing truck, it had about 2000 miles on it when problem first appeared. It sounded like a vibration coming from exhaughst system, mechanics knew what problem was as soon as they heard it. Flat spot on crankcase. Rebuilt lower end, and gave me a 6 year 90000 mile warranty. BIG DEAL.

  Poor Mileage - 2007 GMC Sierra 1500
  By Jim - January 13 - 8:13 am

  Getting 16MPG overall and 10MPG city. All the reviews I read prior to purchase had the truck in the overall 19-22 MPG. Dealer keeps telling me to give it time. This is my third GM truck and never previously experienced such terrible mileage. My 2004 gave me 23 MPG on the highway and 17 in town. Other than the mileage issue it is a tremendous truck. The fuel management system does not work--again dealer tells me to give it time.

  Awesome Truck - 2007 GMC Sierra 1500
  By drdice - November 23 - 12:16 am

  Just purchased this vehicle a few weeks ago. GM has definitely won me back as a customer. Last GM owned was a 96 Blazer. They have finally figured out how to put style into their new vehicles. The truck drives so solid and smooth and exudes quality craftsmanship throughout. I did consider buying a new Tundra but it just didnt have the same curb appeal as the Sierra. Also, the Tundras interior looked and felt very cheap and plasticky compared to the Sierra. I hope this Sierra ends up being as reliable as the Tundra likely will be.

  3rd Sierra...Best Yet - 2007 GMC Sierra 1500
  By uh33nowit - November 22 - 10:10 am

  This is my 3rd Sierra and by far the best theyve made yet. The exterior is simple yet very appealing. The biggest improvement was on the interior. GMC really thought through the location and function in the interior. The fit and finish is much improved over previous versions and the quality of the plastic is much better. The truck rides very smooth and feels much smaller than it is (which is a good thing when driving in traffic and parking). The engine is smooth and delivers quite nicely. The Active Fuel Management so far has been seemless when going from v4 to v8 mode. Currently I have been averaging 15 - 18 mpgs. No complaints

  Oil consumption - 2007 GMC Sierra 1500
  By Shawn - October 9 - 10:46 pm

  Love the truck but Very disappointed with OIL CONSUMPTION Im burning about 2 quarts every 3000 miles. and its not like i abuse the truck Ive changed the oil every 4000 miles and use synthetic oil. I spoke with a gmc dealer today and he says they know of the problem but gmc has done nothing to respond to the problem as a former dodge and ford owner I hope GM does something to fix the problem. Or i guess I will be looking for a new truck and GMC will not be a option. truck has the 5.3 V8 and 33,000 miles on it to date

  Hands Down - 2007 GMC Sierra 1500
  By Smokchasr - August 10 - 8:26 am

  One ten-minute test drive in icy conditions will tell you all you need to know about this trucks capabilities. The traction control and handling give the driver the confidence needed to get where you need to go even when faced with the brutal whiteout and drifting condition. Evidenced by a trip through Snoqualmie Pass when it was closed to tractor-trailer traffic. Two in the morning, no plows out, and 6- 8 inches of wet snow having fallen, and 100 feet visibility. My Sierra passed crawling traffic, breaking through lane burms with ease and control. In order for the driver to feel comfortable in those conditions, the truck has to transition between lanes without tipping or sliding.

  Third Sierra and have loved them all! - 2007 GMC Sierra 1500
  By jmacs97gmc - July 1 - 11:57 am

  Ive have my current Sierra since April, 2007 and the best decision I made was not buying the extended warranty. Ive had no problems whatsoever (knock on wood). Ive read several of the reviews about the issue of oil consumption which I have not experienced, but will pay a little more attention to the issue. I will say, I dont use the oil monitor. I still change my oil about every 3000 to 3500 miles. Old habits and old men are hard to change. Bottom line is although I like the looks of the new Fords and love the interior storage of the Dodge pickups, nothing will get me to walk away from my GMC.

  Truckillac - 2007 GMC Sierra 1500
  By Mike - June 29 - 9:40 am

  Only had this vehicle for a few weeks, but all impressions are great. Always drove Ford F-150s and there is no comparison to this truck. I did a lot of research before purchasing and the GMC rated the highest. This truck is superior in quality, ride and comfort. Have the loaded up SLT with all the options including the 20" wheels. Engine is plenty strong and tranny shifts smooth. My research revealed the GMC is assembled much better than the Chevy. The truck rides like a cadillac as the saying goes. As another rater said of this truck, "Dont waste your time looking at other trucks go to a GMC dealer and purchase the Sierra"! Ill drink to that.
