Review of the 2003 GMC Sonoma

  • We know the value of an old trusty pickup, but in the Sonoma's case, it's just plain old. A redesign is on the way next year, but if you need a compact truck now, we suggest checking out the competition first.

  • Safety
  • Pros

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

  • Cons

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

  • What's New for 2003

    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.

Vehicle: 2003 GMC Sonoma 3dr Extended Cab SLS Rwd SB (2.2L 4cyl 5M)

The '03 GMC Sonoma 3dr extended cab is a good, well running truck that gets from point A to point B.

Vehicle: 2003 GMC Sonoma 3dr Extended Cab SLS Rwd SB (2.2L 4cyl 5M)

Only have 1000 miles on it so far, and it is running very well. This may be why the fuel economy is not up to standard yet. American models seem to be a la carte. In other words, every little thing is extra $$$. The vehicle is peppy on grades, and seems to take weight, in the bed, with ease.




Last of the sonoma pickups

by on
Vehicle: 2003 GMC Sonoma 3dr Extended Cab SLS Rwd SB (2.2L 4cyl 5M)

Recently replaced my 96 Sonoma (130K miles) with a new one. It's the last chance, as next year Sonomas will only come in 4dr/tiny box hybrid models. The larger, higher, worse mileage Canyon will replace the pickup models. The 2003 model is very similar to the last 7 or 8 years worth, still a durable, cheap, relatively small truck. Main differences: Better seats, slightly peppier due to higher axle ratio, elimination of some fun electrical features like lighted vanity mirrors, underhood light, glovebox light.




My sonoma

Vehicle: 2003 GMC Sonoma 3dr Extended Cab SLS Rwd SB (2.2L 4cyl 5M)

I actually own a 2000 Sonoma SLS 3dr ZQ8 V6/automatic, but it's the same exact truck as a 2003 sans the wheel style and radio. I bought this truck on a whim, and I regret it. I like the looks, and when it was new it was the sweetest thing I could find for $21K, so I got it. My truck seems to be the worst Sonoma ever built because everyone I know with one has never had a problem, but mine rattles, creeks, and is slow and gets 16mpg no matter how you drive it. The seats became a little uncomfortable after a year or so, but that's just me.
