Overview & Reviews

The '99 Sonoma touts four new exterior colors, a new steering wheel with mini-module depowered airbag and larger, more robust outside rearview mirrors, with the uplevel power mirror gaining a heated feature. AutoTrac, GM's electronic push-button two-speed transfer case, is now standard on four-wheel-drive models, and all Sonomas get a content theft alarm with remote keyless entry as well as a flash-to-pass headlamp feature for the smart stalk. Serious four-wheelers can now order composite skid plates.

• Sporty styling, fuel-efficient base engine, powerful optional V6.

• Cheesy interior plastics, spotty build quality, low seating positions.

  Good workhorse truck - 1999 GMC Sonoma

  Surprised at how reliable this truck was. The extended cab enabled us to carry personal items, snacks, etc.

  Useful but could be better - 1999 GMC Sonoma
  By Brian - February 4 - 7:56 pm

  I got my truck used with about 54,5xx miles on it. I like the look of the truck, especially looking out over the hood from the drivers seat. Its actually quite pleasant to drive for a truck. The suspension isnt too squishy (floaty). The engine (4.3L V6) has good torque. Has several nice features like power locks and windows. I was surprised to find it had heated mirrors (I wish my car had that). My only beefs so far are: 1) it turns like a boat for such a small vehicle 2) wheel travel is too short. I hit the bumpstops on a back road that I never had a problem with in my Subaru 3)build quality isnt so great. The dash squeaks and the seatback adjustment handles are broken off.

  Love this truck - 1999 GMC Sonoma
  By Sparky79 - January 21 - 2:42 pm

  This is the 2nd Sonoma Ive owned and I love these trucks. They are great to drive and are perfect for light jobs around the house and yard.

  Good Truck - 1999 GMC Sonoma
  By easyrider - July 8 - 2:00 am

  Nice truck overall. Best seats and interior of trucks I looked at. The 4 and automatic combination is very weak on power, but gets the job done. Gas mileage is respectable at 23 MPG. Only problem Ive had is AC compressor which was replaced under extended warranty.

  Fun to drive. Very responsive, quick but very rough ride.

  This truck is too small! - 1999 GMC Sonoma
  By youngblooddale - December 31 - 2:00 am

  This truck is cute, but thats about all it has going for it. There is no leg room, no arm room, put it this way, you might feel more comfortable in an airplane riding in coach. And please dont pick up a passenger, theyll hate you for it. Hopefully you dont live in a town with hills or mountains, because this little guy has no power. This is the type of vehicle you want to test drive for a few days or even rent.

  1999 Sonoma - 1999 GMC Sonoma
  By Zedd - June 28 - 2:00 am

  Good acceleration, rear end has tendency to fish tail on full speed turns (like Freeway exits). I recently had a problem with the heater, it stopped working. Dealer said it wasn’t covered under the warranty because the heater core was clogged. Surfing Edmunds I found there was a TSB about my exact problem. Still the dealer refused to cover it. I called the 800 Customer Care number and after much insistence and a $300 deductible it was fixed. Other than that I have no problems. Its not the greatest on gas mileage.

  I shouldnt want to replace it so much - 1999 GMC Sonoma
  By Butterbear - May 29 - 2:00 am

  At 46,000 miles I shouldnt have to replace it, but it has to go. Now that its out of warranty its shaping up to be a wallet drainer. The drivers door has come loose 2 times The 3rd door handle snapped off 3 times and its out of warranty (100.00+ to fix.) The seat is broken. The GMC dealer would not fix, Funny the Chevy dealer says these are common problems and they would "extend" the warranty to fix if it were a Chevy s-10. I never thought there was a difference between the 2 I was wrong. Its probably the most comfortable vehicle I have ever owned but you cant even get fair wholesale for a trade.

  Faster Than it Looks - 1999 GMC Sonoma
  By 87horizon - February 18 - 2:00 am

  I have the 4.3 V-6 it pulls strong and has been trouble-free, although its starting to develop a leak in the power steering pump at 50,000 miles. The ball-joints had to be replaced at 45,000 miles a part that I feel shouldt be replaced at low mileage. Overall, though, this has been a great little pick-up. GM has always built a good pick-up and this one has been no exception.

  My GMC - 1999 GMC Sonoma
  By SonomaBuyer - November 10 - 2:00 am

  I just bought a 99 GMC Sonoma a little while ago and I love my truck so far no problems or major mechanical stuff so far. I have always loved trucks. How they handle, engine etc and having an american made truck is even better!!
