Analysis
What Problems Does the 2003 GMC Sonoma Have?
Recalls for the 2003 GMC Sonoma were issued for issues related to the fuel system, such as fuel leaks. These leaks posed a fire hazard. Some vehicles were also recalled for potential issues with the brake system. Owners should check the vehicle's VIN with the NHTSA to determine if any recalls apply. Long-term reliability concerns center around the longevity of the automatic transmission and the potential for rust. The interior plastic components are also known to degrade over time, leading to cracks and fading. Earlier model years within this generation (1994-1997) had more reported issues with the central port injection (CPI) system on the 4.3L V6 engine, but this was largely addressed in later years, including 2003. Regular maintenance, including fluid changes and rust prevention, can help mitigate some of these concerns.
How long will the 2003 GMC Sonoma last?
What Technology & Safety Features are Included?
Safety features included standard front airbags and antilock brakes (ABS) were often available as an option, improving braking performance. Some models had daytime running lights. Optional features included things like power windows, power locks, and cruise control, representing the extent of its "tech" offerings.
Crash test ratings from the NHTSA (National Highway Traffic Safety Administration) for the 2003 GMC Sonoma are available. The Sonoma generally received average scores for frontal crash protection. Side-impact crash tests were not commonly performed on vehicles of this class during that era, so data may be limited. The IIHS (Insurance Institute for Highway Safety) may have conducted some tests, and itβs worth researching their archives for available information.
Compared to modern vehicles, the 2003 GMC Sonoma lacked advanced safety and entertainment tech. Its safety relied mainly on basic features like airbags and optional ABS.

How Does the 2003 GMC Sonoma Compare to Other Sport Utility Vehicle Cab; Extended?
In terms of features, the Sonoma offered a fairly basic experience compared to the Tacoma, which was often equipped with more modern amenities even in older models. The S-10, being mechanically identical to the Sonoma, offered similar performance and features at a potentially lower price, making it a worthwhile alternative if badge loyalty isn't a factor. The Ranger occupied a middle ground, with a good balance of features and price.
For reliability, the Toyota Tacoma is arguably the better choice long-term. While possibly more expensive upfront, its durability and lower likelihood of major repairs make it a strong contender. The Ford Ranger is a similar alternative, offering a good balance of price and features, though long-term reliability can vary. If budget is a primary concern and youβre willing to accept the potential for more maintenance, the Sonoma (or its twin, the S-10) can be a viable option, provided it's been well-maintained.

Very reliable vehicleThis car is roomy. It's dependable and comfortable. It's a great travel car. I love this model car. I recommend this car to anyone, it's simply reliable.

Good rugged truck. Lots of power with the 4.3 V6.Styling is great. I have the Zr-2 model and it has a healthy off-road look. I drive it off road sometimes and hit handles very well. The engine is very good, very smooth, and very durable. The 4 wheel disc brakes are super. Gas mileage is not so good, however. It gets 17-18 on the highway and less in the city or if there is a load in the back. Gas mileage is not so good.

Problem with ergonomicsI just bought this 2003 for its low miles, to use for highway. Pass door was crunched and mirror post damaged in a parking lot incident, which lowered the price . Electric mirror still works. This rig must have the luxe package, with the power windows etc. My issue: The "plane" for the brake and gas pedals. The gas pedal is 3 inches further away than the brake. On my 2002 Tacoma, the difference is only 1.5 inches. I have to stretch my leg more than I like, for the gas, plus the pedal is very stiff (maybe some WD40 will fix that). Moving the seat more forward does not work well, just pushes the steering wheel into me. I am male, 5'10" , 140 lbs. We are going to experiment with bonding a 3/4 inch piece of wood to the gas pedal! After the first 500 miles, this has become a really annoying issue, more than it should be, this almost out-of-reach gas pedal - we live in mountains, lotsa hills. 4x4 I have not really used yet, I like lever-on-floor better than electric, but minor detail perhaps. Instead of two tiny seats in the "extra cab" area, there is just one, in which a passenger sits astride, more room to stretch out. Cheapskate gmc would not even include a CLOCK which surprised me, they could buy for $3 about. Once we get the seat/gas pedal ratio problem solved, the little truck should be a handy rig for me.

Great Truck for the MoneyRecently purchased a used 2003 GMC Sonoma with the ZR-2 package. This review is based on when the truck was made and not comparing it to today's trucks since it is 9 years old and things have changed a lot in 9 years. Currently the truck has 108,000 miles and runs like a champ. It gets driven 300 miles a week commuting to work and my car is driven on the weekends unless truck is needed for work around the the house. Like all older GM vehicles, as long as they are maintained and taken care of, they will run forever. My Sonoma is no different. Runs great, still putting out solid power from the 4.3 V6, and gets decent mileage for a truck at 17MPG. A K&N Cold Air Intake is installed and does provide smoother running and slight bump in power. There are the normal cracks, creaks, and rattles that happen over time since the interior is really just cheap plastic. Besides that it rides well with the larger 31" tires and is great off road. Normal repairs such as bushings, tie rods, UV joints have been done. Ride can be bumpy at times but it is a truck and rides as expected. Besides the cheap interior build quality, this is another example of a quality GM truck that when taken care of, will run well and will be reliable for many more miles as I expect to reach at least 150,000 miles with my ZR-2. This is my second S-10 as previous truck was a 1992 with the Tahoe package. These trucks are priced well at the time of this review and are cheap and easy to maintain. The ZR-2 package also adds a nice unique look to the truck.

wowzathis little thing is a tank. Went camping and used it to toe our family boat (18ft silverline) on a 5 hour drive up to northern BC (Kamploops to be exact) and it did it easily. i was passing other trucks like nothing. as this is my first vehicle and i am in my 20's i have put in a CAI and did a muffler swap and got it at 200HP from 190HP. parts are cheap. most expensive thing i had to do to it was change the distributor. other than that just the usual breaks, oil, etc. its a 2wd and it is surprisingly good through the BC back roads, sloshing thru puddles and mud. definitely surprised some of the bigger truck owners. this thing is a tank in the snow haven't gotten stuck once and have had it for about 4 years. and its a GMC so you know it wont be Found On Road Dead.

Pretty good little truckThis is a good little pickup. can hold a nice size payload of about 1000 lbs with no problems. The power train barely notices a load this heavy. The only thing to go wrong is the radiator went at about 70k miles. Overall it has been a good vehicle no major complaints
GMC GUY on June 9, 2010
Can't beat it for the price!This was the least expensive new small truck I could find! After 150,000 miles without ANY real problems, I know you can't beat it for reliability. It is easy to drive and park. I drive 2 hours a day, mostly highway and it has been dependable in all driving conditions. You can't expect a compact, economy truck to give you the same power and comfort you would get from larger, more expensive vehicles, but this little guy does what it was made to do, and it does it cheap! The small truck has some advantages over small cars, because it has a full frame. I have hauled with it, and it will handle a half-ton load as it should. I would not recommend putting more than that in it, because it IS a light duty truck. Mine is the long box version, and with the help of some 2X6's you can actually haul 4X8 material with the gate down. It will handle a yard of mulch just fine. It's great for yard work, because it's light and small, and it's easy to load and unload, because it is lower to the ground than a full-size. This has been a great truck for the money!
Former GMC Sonoma Owner on May 14, 2010
Wouldn't buy anotherI owned a 2003 GMC Sonoma Flareside and I would advise against buying one. There was a problem with the front end shimming and as many times as I took it back to the dealer to be repaired it could not be fixed. The third door was repaired at least four times and that was never right either. Mechanically it did run well.
