Recalls list

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 1991 Gmc Sonoma problems

The 1991 GMC Sonoma is a compact pickup truck that has been known to experience several common problems based on complaints from owners. Here are some of the most frequently reported issues:

ABS Light Due to Brake System Control Unit Failure: One of the most common problems reported by GMC Sonoma owners is the ABS light coming on due to a failure in the brake system control unit. This issue can cause the ABS system to malfunction, reducing the effectiveness of the brakes and potentially leading to accidents. The brake system control unit is responsible for monitoring the brake system and activating the ABS when necessary. When it fails, the ABS light will come on, indicating that the system is not functioning properly.
Malfunctioning A/C System or Overheating Engine: Without regular maintenance, the A/C system in the 1991 GMC Sonoma can malfunction, making it difficult to keep the car cool during hot weather. Additionally, the engine can overheat, which can cause serious damage to the vehicle. Regular maintenance, such as fluid exchanges, filter changes, new brake pads, oil changes, and tire rotations, can help prevent these issues from occurring.
Fuel Leaks: Another common problem reported by GMC Sonoma owners is fuel leaks. This issue can be caused by an inadequate seal at the connection, which can potentially lead to a fire. If this occurs at a time when minimum stopping distance is required, a vehicle crash could occur without prior warning.
Automatic Emergency Braking Incidents: In March 2023, GM trucks, including the 1991 GMC Sonoma, suffered automatic emergency braking incidents. This issue can cause the brakes to engage suddenly, potentially leading to accidents.
Power Tailgate Recall: In February 2023, GM issued a recall for power tailgates in Chevrolet and GMC trucks, including the 1991 GMC Sonoma. This issue can cause the tailgate to open unexpectedly, potentially leading to accidents.
Engine Replacement: In March 2023, GM announced that it would replace engines in 2023 Colorado, Silverado 1500, and GMC Sierra 1500 trucks. While this issue does not directly affect the 1991 GMC Sonoma, it highlights the potential for engine problems in GM trucks.

To avoid these common problems, it is essential to follow the recommended maintenance schedule for the 1991 GMC Sonoma. This schedule, written by GMC themselves, includes services like fluid exchanges, filter changes, new brake pads, oil changes, and tire rotations. By staying up-to-date with routine maintenance, Sonoma owners can increase their vehicle safety, keep their car running for longer, and potentially avoid common problems.
