2008 Pontiac Grand Prix Problems
You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned then the transmission system should be completely flushed.
Contaminated brake fluid can cause problems in the brake system and it should be flushed every 60,000 miles.
Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
