Sold as a full-sized pickup truck, the GMC C1500 was sold from 1995 to 1999 before being replaced by the GMC Sierra. When launched in 1995, it received a lot of upgrades and revisions to differentiate it from the third-generation Chevrolet C truck it was based on. Now with the vehicle out of production, used models are being sold in the market. For those who are looking to buy this truck or have just purchased one, be wary of some common problems involving GMC C1500 parts and performance.
Many GMC C1500 owners found that their vehicle's anti-lock braking system (ABS) is not working properly. This failure was discovered after GMC dealers installed new brakes to the vehicle, but the new component didn't work properly. Instead of having this problem repaired elsewhere, GMC owners brought the vehicle back to the dealer who then found that there was a problem with the ABS.
Other service brakes failure include the brake pressure module valve, brake anti-lock control unit, and brake pedal and linkage.
Owners also reported that the steering speed sensor of their C1500 sometimes fails, causing the steering to suddenly jerk while turning at a corner. According to the drivers who had experienced this, the motion felt like the front wheels were hitting slippery ice.
Steering also becomes loose while the truck is cruising on curved roads, causing drivers to lose control of their vehicle. Some had even come close to an accident, leading many concerned owners to complain to GMC dealers. However, what they only got was a response saying that since there was no recall from the manufacturer, there should be nothing to worry about.
Some owners have problems seeing the road while driving, which is often caused by faulty windshield wipers. Drivers said that they don't always work, but they can be moved by hand, suggesting a short of some kind in the wiper's system. What's dangerous about this is when the wipers stop and the blades remain in the driver's line of sight, causing a major distraction. Other incidents include the wipers suddenly stopping during intermittent setting or even the component not stopping at all even after it's switched off.
