GMC Jimmy Problems

ABS Light Due to Brake System Control Unit Failure

The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.

Transmission Output Seal May Leak and Mount Replacement

A fluid leak may develop from the transmission output shaft seal. This leak may cause the transmission mount to become oil soaked and require replacement of the mount along with the leak repair.

Replace Fuel Filter Every 30,000 to Prevent Fuel Pump Failure

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.
