2003 Chevrolet S10 problems

The Chevrolet S-10 is a compact pickup truck produced by Chevrolet. It was the first domestically-built compact pickup of the big three American automakers. When it was first introduced as a "quarter-ton pickup" in 1981 for the 1982 model year, the GMC version was known as the S-15 and later renamed the GMC Sonoma. A high-performance version of the latter was released in 1991, called "Syclone." The pickup was also sold by Isuzu as the Hombre from 1996 through 2000, but only in North America. There was also an SUV version, the Chevrolet S-10 Blazer/GMC S-15 Jimmy. An electric version was leased as a fleet vehicle in 1997 and 1998. These models are sometimes internally referred to as the S/T series to denote two and four wheel drive models respectively (similar to the full size Chevrolet C/K trucks) despite all versions being badged with 'S' nomenclature.
In North America, the S-series was replaced by the Chevrolet Colorado, GMC Canyon, and Isuzu i-Series in 2004.
The S-Series ended production in Brazil in 2012, being replaced by the Chevrolet Colorado, but still with the name S-10.

Common 2003 Chevrolet S10 problems
The Chevrolet S10, produced from 1994 to 2004, is a popular pickup truck known for its reliability and versatility. However, like any vehicle, it can experience certain issues over time. Here are some of the most common problems reported by S10 owners:
- Upper Control Arms: The upper control arms can wear out, leading to steering issues and a rough ride. In some cases, the entire control arm may need to be replaced, especially if it is rusted or corroded .
- Fuel Level Sensor: The fuel level sensor, located in the fuel tank, can become faulty, leading to erratic fuel gauge readings and inaccurate fuel level readings. Replacing the sensor requires removing the fuel tank, which can be a challenging task .
- MAP Sensor: The manifold absolute pressure (MAP) sensor can become faulty, leading to issues with engine performance, fuel economy, and acceleration. Replacing the sensor is a relatively straightforward task that requires removing the sensor from the intake manifold and disconnecting the electrical connector .
- ABS Light Due to Brake System Control Unit Failure: This issue can lead to the ABS light illuminating on the dashboard, indicating a problem with the brake system. This issue may require replacement of the brake system control unit.
- 4x4 Not Working: The 4x4 system on the S10 can experience issues, particularly in winter conditions. This issue may be caused by a vacuum actuator failure, which can be diagnosed by checking the vacuum actuator under the battery tray .
In summary, the Chevrolet S10 is a reliable and versatile pickup truck, but like any vehicle, it can experience certain issues over time. Common problems reported by S10 owners include coolant and oil leaks, faulty heater cores, worn-out upper control arms, faulty fuel level sensors, and issues with the MAP sensor and 4x4 system. Regular maintenance and timely repairs can help ensure the longevity and reliability of the S10.

Purchased new in '03, this truck has been a reliable companion with only a battery replacement and a few exterior lamps needed. With 48000 miles on the original tires, it's clear that good preventive maintenance is the key to keeping this truck running smoothly. While the V6 4.3l engine can be a bit rough on the wallet with gas prices as they are, this truck can certainly get out of its own way when it needs to.

This is my second S10, the first was a 1989 regular cab 4x4. After 9 years and 199000 miles, I got out of the truck and owned a couple of cars. Now I've come back to the S10. I'm absolutely loving it so far!
-
The ZR2 package is definitely one of the best available options for the S10. With a heavier drive train, suspension, lift kit, and bigger tires, it makes for one of the best stock off-road trucks with great value for money.
-
Though my ZR2 is a 2002, I must say that this truck is amazing! I have taken it to the toughest off-roading spots and it outperforms all other trucks in its class. I have even towed Jeeps out of jams! For those concerned about gas mileage, don't worry, after the break-in period, the gas mileage will improve dramatically. I hope the Colorado will continue the legacy of the ZR2!

Your truck looks amazing! It's great to hear that it can handle any obstacle with ease, and the lift kit and big tires give it a really cool and tough appearance. I also love the third door option and the fact that it has good mileage. It's impressive that you can tow your toys without any problems, and the truck handles off-road adventures like a pro. It's clear that GM did an excellent job with the ZR2, and it's a shame that it won't be available in '04. Hopefully, the Colorado will continue the tradition. Well done!

As an ex-GM tech, I can confidently say that my truck has had its fair share of issues. Over the past 3 years, I have had to replace a long list of parts including the battery, tires, heater core, brakes rotors, cv driveaxles, front wheel hub bearings, slave cylinder, clutch assembly, gasket set for upper engine, fuel injectors, fuel pump asy air conditioner compressor, upper and lower ball joints, catalytic converter, and even the 3rd door handle (which I made out of stainless steel to save money). Recently, I had to replace the mass airflow sensor and 2nd gear synchro gear. Despite all of these issues, I am grateful for my experience as a GM tech and the fact that I did not have to pay for labor. However, I sympathize with those who have had to pay for these repairs and understand why GM is facing financial difficulties.

I purchased this vehicle hoping for decent fuel mileage, but I was a little disappointed. However, the power is great and it has been a reliable truck so far.
Chester Dach 2025-04-11
This truck is a great choice for commercial use, as it is designed for tough and dirty jobs. While it may not be the most stylish option, it gets the job done. Think of it as a Blazer with a more practical design. If you're interested, be sure to check out the 2004 Chevy Colorado on our website!

This car has had some issues, but they have all been addressed promptly and professionally. Despite needing a new exhaust and some repairs to the transfer case and A/C lines, as well as some other minor issues, the car has been well-maintained and is still under 27,000 miles. The service engine soon light recently came on, but the car is currently being serviced and the issue will be resolved soon. Overall, this car is in good condition and has been well taken care of.
Alejandrin Rutherford 2025-02-20
Bought brand new in June 2003, this car was an excellent value at the time of purchase. Initially, it was a temporary replacement for my daily driver that needed transmission repair. However, I was extremely satisfied with its overall performance, averaging 24-25 mpg and requiring cheap maintenance. I was pleasantly surprised that it never broke down in the 4 years and 50k miles that I held onto it. I may just keep it until another great deal comes along!
