Report A Problem

The direct ignition cassette can fail causing the engine to die while driving, and/or it will crank but not start. The engine may also have a rough idle and run roughly. Diagnosis may discover trouble codes for random misfires.

The exhaust flex pipe can fail causing excessive exhaust noise from the front/center area of the vehicle. The flex pipe is a flexible joint in the exhaust that allows for engine movement.

If the HID head lights are flickering or have failed, it may be caused by the window washer fluid leaking onto the HID modules. The washer fluid check valve for the head light washers develops the leak and drips onto the modules mounted under the head light assemblies.

The water pump can fail causing noise on the left side of the engine and overheating. Other symptoms include coolant loss and leakage at the front/left area of the engine.

 

Coolant loss may be caused by leakage around the thermostat. Leakage will be visible between the cylinder heads, on the left side.

The rear shock absorbers can fail on the wagon models creating a bouncy ride from the rear of the vehicle.

Coolant leakage between the cylinder heads can be caused by failure of the oil cooler cover seal. Mixing of oil and coolant is possible and would be seen in the coolant expansion tank.

The idler pulley for the serpentine belt can fail causing noise from the belt area. Our technicians report the pulley has been known to fail completely which can cause the belt to break or be thrown off.

The electrical contact on the starter solenoid can come loose causing a problem where the starter intermittently does not crank.

Oil leaks from the timing cover, valve cover, and/or rear main seal may be due to excessive crankcase pressure. An updated PCV (Positive Crankcase Ventilation) kit was released to fix this concern.

The Check Engine Light may come on because the electronic throttle body has failed. Other symptoms include loss of acceleration, a high idle or failure to return to idle, and difficulty starting.

The head gasket may leak oil externally. The oil will be visible around the cylinder head and block area.

Coolant loss may be caused by leakage around the thermostat. Leakage will be visible around the thermostat at the right, rear area of the cylinder head.

The fuel pump check valve may have failed if the engine requires more cranking before it starts. The check valve is a one way valve that maintains the pressure in the fuel lines so the engine is easier to start after it has sat a while.
