Introduced in January, 1990, Sonoma is a S15 Pickup with a new name and an exterior facelift that includes a new grille, fresh trim and restyled wheels. Four-wheel drive models get the 4.3-liter V6 as standard equipment. High Sierra trim is dropped, and Sierra Classic trim is changed to SLE. Midyear, the base four-cylinder powerplant gets more horsepower.

Tough little Truck

Andrew, 01/18/2010

1991 GMC Sonoma 2dr Regular Cab SB (2.5L 4cyl naturally aspired 5M)

283,000+ miles and still the original motor and tranny. Only repairs (besides regular maintenance) has been fuel pump, altenator, water pump, and rear axle-wheel seal. Not bad at all though considering the mileage. Purchased from my dad when it had 190,00 miles. He bought it in 92 with only about 40,00 miles.

Good truck

1991 GMC Sonoma SLE 2dr Regular Cab 4WD SB (4.3L 6cyl naturally aspired 5M)

Bought this Sonoma used, from private party, but was a previous utility company truck. It had about 70,000 miles then, and now has 130,000. It's handy, and has hauled well over a ton(!) in the bed, plus towing a heavy trailer. The 4wd shift lever on the floor is far superior to the later push-button models, which are much more complicated, more expensive to repair, and cannot be shifted …

One truck I'll never sell

1991 GMC Sonoma SLE 2dr Extended Cab 4WD SB (4.3L 6cyl naturally aspired 5M)

This is my fourth pickup and the best I've ever owned. She's towed an 18 foot Boston Whaler with a motorcycle in the bed without a problem. I have 193,000 miles on the truck (5 speed) and have never had to do any powertrain work other than change the fluids. She's had problems here and there but has never left me stranded. I can't count the number of times I'd had stuff piled above …

Lemon! The worst vehicle I ever bought.

1991 GMC Sonoma 2dr Regular Cab SB (2.5L 4cyl naturally aspired 5M)

I needed a small truck for running errands. This truck was available to me so I hurried and just bought it. AT the time it only had 18.900 miles on it. This must have been a factory lemon because I had nothing but problems with it. It had some warranty left on it but I cant spend all of my time at the dealership. A dealer in Nampa, Idaho worked on it 3 times trying to fix the engine …
