GMC Jimmy Repair and Maintenance

A guide to problems, costs, maintenance and repair for your GMC Jimmy

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

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.

The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.
