Overview & Reviews

While the compact pickup truck segment exploded in popularity during the late 1970s, the American automakers were initially MIA. GMC got with the program in the early '80s with its S-15 pickup, which quickly found itself in the thick of the action. Eventually renamed the GMC Sonoma, this truck was affordable, versatile and a lot easier on gas and in tight parking situations than a full-size pickup.

Although the S-15 and Sonoma were in production for more than two decades, there were just two generations. Considering that the first generation ended back in the early '90s, most used-pickup shoppers will be looking at the second generation. This Sonoma was a definite improvement over the earlier model, as it boasted more power and convenience features. Still, the Sonoma's lack of overall development compared to its constantly improving domestic and Japanese rivals makes it hard to recommend.

Most Recent GMC Sonoma

The second-generation GMC Sonoma was produced from 1994-2004. It was offered in regular, extended and (later on) crew cab bodies with short and long beds. Engine choices included a 2.2-liter four-cylinder (118 horsepower), a 4.3-liter V6 (165 hp) and the Vortec 4.3-liter V6 (195 hp). All three engines were available with either five-speed manual or four-speed automatic transmissions, and four-wheel drive was optional.

Trim levels typically consisted of base SL, midlevel SLS and luxury SLE. The SL was a stripper with vinyl bench seating and the SLS added cloth upholstery, air-conditioning, cruise control, foglights and alloy wheels. The SLE added chrome exterior trim, more luxurious seating and full power accessories.

The aptly-named Highrider package was available in '94 and turned the Sonoma into a serious off-road rig thanks to its wider track, 3-inch increase in ground clearance, beefed-up suspension, big tires and skid plates.

The Sportside bed arrived in 1996 along with the optional three-door access cab that aided loading cargo, pets or an unfortunate passenger into the rear compartment with its fold-down jump seat. This year also brought standard ABS for all GMC Sonoma models as well as the available "ZQ8" sport suspension package that featured 16-inch alloy wheels (versus the stock 15s), quicker steering and a lower ride height.

Unfortunately, safety and interior build quality weren't strong points with the Sonoma. A driver airbag became available in 1995, but there was no passenger protection until the 1998 update. The cabin was comprised chiefly of hard plastics, a glaring fault that was mentioned in virtually every review of this truck. For these reasons we'd steer clear of these early second-generation Sonomas.

A better option might be to look at the later models that underwent the midcycle '98 freshening; this included more aggressive front styling and an improved interior with dual airbags. The only other major change for this generation's run was 2001's new four-door crew cab model with five-passenger capacity.

The GMC Sonoma was seemingly loaded with value and versatility for the compact pickup truck buyer, but we were never thrilled with it. The revised interior featured good ergonomics, but the materials were still low-rent, and the driver sat low, facing a tall steering wheel and dash. The Sonoma's tendency to squeak and rattle didn't provide the feeling of brawny quality we'd like from a pickup, nor did lousy crash test scores.

In a comparison test we conducted for 2001, the Sonoma's Chevrolet twin, the S-10, finished fifth out of five trucks. Production soldiered on until 2004, at which point GMC replaced the Sonoma with the all-new Canyon.

Previous GMC Sonomas

The original S-15 was offered from 1982-'90 and the renamed Sonoma version from 1991-'93. Either way, the GMC was a twin to the Chevrolet S-10, save for a slightly different grille and taillight treatment. The S-15 was available in extended and regular cab styles, with the latter available in two wheelbases. Engine choices consisted of the typical four- and six-cylinder mills. Initially, output was weak, at 84 hp and 110 hp, respectively. The burly 4.3-liter V6 debuted for '88, sporting 150 hp and by the end of this run would make a full 190 hp.

For 1991 the Sonoma name replaced S-15 and the same year marked the debut of the asphalt-melting Syclone, one of the quickest GM trucks ever produced. Sporting a turbocharged 4.3-liter V6 that ran through a four-speed Corvette automatic transmission and then to all four wheels, the Syclone could blast to 60 mph in under 5 seconds and give any muscle car from the late '60s a run for the money with its 13-second quarter-mile performance. That beast was produced for just one year. The next year brought the visually similar Sonoma GT (which lacked the muscle-bound turbo engine) as well as an electronic transfer case for 4WD Sonomas. The GMC Sonoma continued through '93 mostly unchanged in the face of the following year's redesign.

  Great (SO FAR) Minor stuff only - 2001 GMC Sonoma
  By Trout Terminator - February 16 - 2:00 am

  Bought this little gem to cart around the oompa loompas and haul the boat, 17 foot Starcraft (2300) lbs. This truck does it all very very well. Good to fair gas mileage. (not bad for a semi- thristy v-6). I get good mileage with A/C on full blast also. Truck doesnt mind a/c when towing and doesnt lose power. Has a little bit of a knock when you floor it....49k miles and have only replaced the battery. (delco batteries arent top quality). Gas gauge failed at 41k, thank god I bought extended warranty. I still paid $140 out of my pocket to fix gauge. I paid 18,600 used, 14k miles on it originally. I think price equals value here.

  poor performance - 1994 GMC Sonoma
  By Eric C - January 18 - 2:00 am

  Well first off the truck is a overall good truck, but the performance stinks. I definatelly recommend the best top of the line tires for traction. The brake system in it is awful, and it will skid or turn sideways very easily. How this truck hasnt caused more rear end collisions is a miracle, and but by God I think it would have. The brakes lock up and it takes forever to get this thing to stop, have been told was a problem with the anti lock braking system in them back them. I suggest you use pleny of room for stopping when driving especially if the road is wet at all, and be very careful, and never ever drive on snow, or else you got really good insurance.

  I love my truck - 2003 GMC Sonoma
  By Me and my truck - January 15 - 2:00 am

  I have had nothing but great experiences with my truck, It was a spur of the moment decision to buy this truck when it caught my eye on the dealer lot because it is flame yellow. When I first drove it I knew it was the one. Ive had minor problems with the heater controls and passenger door seals, but i took it to the dealership and they got it fixed right away under warranty. The towing capacity is increadible for a small truck, I can just fit my 600lb quad in the back which you hardly notice is there,you can still hook a trailer behind load it up and pull the hills to the mountains without a problem. Love the 4.3.

  Problem child to good citizen - 1995 GMC Sonoma
  By Rwm - January 13 - 2:00 am

  I purchased my used sonoma with 4,000 miles. Within the first year of owning my truck I visited the GMC dealer for the replacement of my rear axis, starter, carberator, clusters board, various fuses, breaking system, anti-lock breaks, wiper blade motor, leaking hose for air condition system, leaking hose for exhaust system and other minor repairs. My thoughts were that the prior owner damaged the truck before resaling, because after those parts were replaced (free of charge) my truck is running fine.

  Petes Review - 1994 GMC Sonoma
  By Pete Matthiesen - January 6 - 2:00 am

  I have really enjoyed my Sonoma. It has been a very reliable truck with minimal problems. It has over 130,000 miles now and is still running strong as when I bought it. The only problem I have had is with the EGR on the engine, but they say it is a common problem with it.

  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.

  Not worth the purchase - 2003 GMC Sonoma
  By Alaska Owner - December 26 - 2:00 am

  I have had nothing but trouble form the start. The quality is very poor. The doors seem that they dont hold a seal. Various engine problems too. Find a different truck. Dont want you as a buyer to go through what I am going through.

  Solid Truck - 2003 GMC Sonoma
  By walkmn - December 15 - 2:00 am

  I love the solid feel of this truck and I have full confidence when I depart the pavement to go hunting, fishing, or just plain exploring! This truck is ready for anything you can throw at it. Even the underbody composite skid plates let you know this truck means business! GM should however, take lessons from Japan regarding their build quality. Cheap interior parts and shoddy workmanship may force me to shop around a little longer for my next truck. Despite the questionable interior materials, I really do love my truck overall, and dont regret buying it what so ever. Consider this truck if you you want a highly-capable, mid-sized truck.

  Read your manual - 2003 GMC Sonoma
  By moat - December 13 - 2:00 am

  If I had read the owners manual before buying I would not own this GMC. The maintenance schedule is the one I maintained on l950 vintage vehicles. Unbelievable. The gas milage of 19-25 was more like 13.5 in the summer (4cyl. w/ac} I bought the vehicle for handicapped passenger comfort and discovered the floor is uneven on the passanger side. There is no storage space under the seats and hardly can get anything behind the seat.
