2001 Pontiac Bonneville Problems

Water Pump May Fail Prematurely

The water pump may develop a coolant leak resulting in an engine overheating condition.

 

Fuel Level Sensor Failure

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

Mode/Temperature Door Actuators May Fail

The mode and temperature door actuators may fail causing improper air flow or temperature output from the heating and AC (HVAC) system.

2001 Pontiac Bonneville Reviews

This is my second Bonni and I just love it. I have had only minor problems from it and with good maintenance, it runs great! Right now it has 160,000 miles and still running strong.
