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.

  99 Sonoma SLS 4.3, v6, 4x4, 3 door - 1999 GMC Sonoma
  By herb25 - March 31 - 11:02 pm

  After going through 3 cars that did not last as long as they should have, I got this truck last year. It had 200000kms on it, the motor sounded like new. The previous owner did not replace the faulty gas gauge which meant changing the fuel pump. I ran out of gas twice before I learned and had the fuel pump replaced (the faulty sending unit is part of the pump). Also the passenger seat would not recline, a mistake at the factory so I bought a parts truck ( 2000 Blazer ) and took the seat from it. I got the truck for $6000, safieted and etested, but so far I have had to replace the rear brake lines, and 3 calipers, gas tank, fuel pump, and rad, signal light switch.

  I was surprised how this truck handles in corners, I didnt expect that GM has some great things in their products. Well built and very reliable

  ZR2 Rocks - 1999 GMC Sonoma
  By Tim - June 8 - 10:28 pm

  Got this truck with 90,000 miles on it. I have the 4.3 Vortec V6. Has 165,xxx now and still running great. Only replaced fuel pump and idler arms. I love the ZR2 (high rider) off road package and 4x4--never get stuck. It handles great and looks sharp. Great for outdoor activities (hunting, camping, fishing) and general all-around use. Love this truck. Reliable. Solidly built. Decent gas mileage. Fun to drive.

  99 2wd reg cab 4 cyl first truck owned - 1999 GMC Sonoma
  By brian - June 16 - 11:24 am

  I got this truck a few months ago and it was a good price compared to other trucks. I had to recharge air and works great very cold and its 10 years old. I have drove many other trucks and this drives great. Needs new fuel regulator so gas gauge dont work so the only problem is that, and the fact we figured it out to only get about 19-20 mpg mf sticker in glove box says 19-28mpg it would not get 28 mpg on the best day. drivers door rust spot on bottom and wheel undercarriages and very squeaky when driving I heard people say that about gm,my grandpa worked there 34 years so beside 2 mustangs all i ever owned was gm this only one that squeaky, bought w 99950 miles will get probably 200,000

  By truck - May 29 - 8:59 pm

  Great truck. 28mgp highway. Not a lot of power but has 2.2 5 speed. All had to do was the brakes at 70k today. Just over 100k. Great value

  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.

  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.

  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.
