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.

  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.

  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

  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.
