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.

  Great ride for a truck - 1999 GMC Sonoma
  By rocket3 - November 4 - 2:00 am

  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

  Happy Sonoma owner - 1999 GMC Sonoma
  By KENNE-BILL - September 20 - 10:36 pm

  Ive owned my 99 Sonoma for about a month now and am very happy with it. I bought it used with 69,000 miles on it, body is solid and rust free and the original white paint still looks decent. As far as I can tell everything still works on the truck except for a bad AC compressor that I have already replaced. Its a regular cab, 2.2l with a 5 speed trans, Im happy with the acceleration. I calculated 26 mpg on my first tank of gas which is why I stepped up to a 4 cylinder truck, my old 92 Sonoma with a 4.3/auto was getting only about 17.5 mpg.

  SLS Ext 2.2 Man - 1999 GMC Sonoma
  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

  Low Cost ,Reliable, Great Vehicle - 1999 GMC Sonoma
  By R Krebs - December 6 - 10:53 am

  Purchase new eight years ago. 26 MPG. Truck receives scheduled maintenance, and has performed flawlessly. Radio was replaced (defective from factory), one set of brakes and 2 sets of tires in 105,000 miles. Orig. exhaust and clutch, water pump, etc. 4 cyl. is underpowered, interior is stylish but uncomfortable for the passenger b/c of uneven floor. Small passenger compartment cools down really fast in the summer and heats up fast in the winter. Great vehicle for commuting or suburban 2nd car. With a low end price tag this vehicle has exceeded my expectations for 8 years now!

  Low cost utility - 1999 GMC Sonoma
  By dave8697 - September 12 - 11:59 am

  Bought mine with 88,000 miles on it and a/c and dash lights broken. Needs alignment and one ball joint has some wear. Used to own a 2000 S-10 so I knew what to expect. Previous owner replaced alternator and water pump. Ive put a rebuilt a/c in it. For an 8 year old truck, it has only been in shop twice. Got 25.5 mpg on 1200 mile trip. Seats OK, brakes very good. Carried 1200 lb load with no problem.

  Lots of good to go with the bad - 1999 GMC Sonoma
  By dave8697 - June 11 - 6:31 pm

  Purchased with 88k miles and now at 91500 miles. Original owner had the usual GM low priced vehicle problems like alternator, a/c, water pump and some bulbs out. No care ever taken of it and I had to restore it but now with new tires, front brakes, and about $100 spent on little stuff, it is fun to own and drive. So far it gets 25-26 mpg whether local or on the 1200 mile trip I took. Enjoyment will increase after I get the A/C fixed.

  My Sonomoa Lexus - 1999 GMC Sonoma
  By rich lloyd - March 9 - 3:49 pm

  What a great little truck. Only problem in 57000 mi were left power window, cd player, alt., compressor. Normal stuff. Beautiful interior. Cant believe GM built such an ugly interior on their follow up Colorado. I call it the Lexus of small trucks and will be keeping for many more years or until GM builds something as nice
