2005 Buick Park Avenue Problems
RepairPal has identified the most common problems with the 2005 Buick Park Avenue based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.
The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.
The mode and temperature door actuators may fail causing improper air flow or temperature output from the heating and AC (HVAC) system.
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.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
