Overview & Reviews

The Sonoma gets a few changes for what will be the final year of production of the current model. There's a new split-folding bench seat on all two-wheel-drive models, new seat materials, an optional six-disc CD changer and a sport package for crew-cab models.

• Multiple configurations, fuel-efficient base engine, torquey V6.

• Low-buck interior, spotty build quality, poor resale value.

  I could design a better truck! - 2003 GMC Sonoma
  By Conserned Customer - December 30 - 8:40 pm

  First off, bought the truck on GMs reputation. Decent design, good comfort, but performance, and gas mileage is something to be desired. I had a 96 Nissan 4 banger that would run circles around this GMC. Come on guys get with it.

  Poor quality - 2003 GMC Sonoma
  By Tim R - June 16 - 1:53 pm

  Had to get a new transfer case at 10,000 miles. Oil pickup tube fell into gears and ruined transfer case. Replaced air conditioner compressor at 42,000 miles. Transmission is now slipping badly. Fuel filler neck has been replaced, but still overflows when refueling. Leaf spring bushings are noisy. Would not buy again.

  I like my truck. - 2003 GMC Sonoma

  I like my truck. Havent had any major problems in 40,000 miles. The drivers seat is comfortable for long trips, but the back seat will only hold adults for short trips. The radio is good for stock. This is a good truck. It always starts easily, even in cold weather, but Im not sure I can afford the gas.

  Terrible Attempt at a Truck - 2003 GMC Sonoma
  By Bruce - October 20 - 4:17 pm

  Ive had this truck for 2 years now and I absolutely hate it. A friend had one and I thought that it looked good, so I bought it without testing it at all. What a dumb move. It gets terrible fuel economy. Has absolutely no power, terrible, no passing power at all, no bottom end. Have to put it into 4X4 low to get any power. That is where it is actually good. In the mud it is great, cause it is so light. The 4X4 low will crawl along at 200 rpm. However, the interior is way too small, and I sit so that my hip is bent and bothers me amazingly on long trips. But, it is in the shop as we speak having the transfer case replaced (50063 km).

  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.
