If the engine will crank but not start, it may be the fuel pump has failed. Diagnosis may find no fuel pressure when attempting to start the engine.
The head gasket may leak oil externally. The oil will be visible around the cylinder head and block area.
The rear shock absorbers can fail on the wagon models creating a bouncy ride from the rear of the vehicle.
The air conditioning expansion valve can fail causing poor, or no cooling from the AC system.
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 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.
