Known Problems

The high pressure power steering hose will commonly leak fluid; it should be replaced.

Front brake rotors can wear causing a pulsation felt in the brake pedal. Our technicians tell us this condition is best corrected by replacement of the front rotors and brake pads.

This engine may leak oil from the valve cover gasket.

The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.

Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.

Our technicians highly recommend that the engine coolant be replaced every 30,000 miles.

Fuel injectors can short-circuit electrically causing a rougher than normal idle and reduced performance.

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.

A ticking noise may develop from the engine due to a cracked exhaust manifold. Damaged exhaust manifolds will require replacement to correct this issue.

The torque converter clutch can stick "on" after extended freeway driving causing the engine to stall when coming to a stop. Our technicians tell us when this occurs, the engine usually will restart and stall when put into gear. After allowing about twenty minutes for the engine and transmission to cool down, the engine will start and the transmission will operate normally. Replacing the torque converter clutch solenoid, transmission filter, and fluid will generally correct this issue.
