The air conditioning system can be prone to refrigerant leaks and failure of one or more pressure sensors. The AC pressure sensors should be checked for proper operation when ever the AC system is serviced.
A Loose or worn gas cap may cause Check Engine Light to illuminate.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
The anti-lock brake (ABS) accumulator may fail causing loss of power brake assist. (The brake pedal will become very hard.)
The fuel pump may fail causing the engine to stall and not restart.
The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.
A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
The crankshaft position sensor, ignition module, and/or powertrain control module (PCM) may fail resulting in illumination of the Check Engine Light with ignition system related fault codes stored in the PCM. Patience is necessary when dealing with this specific situation as normal diagnostic procedures are not effective. In many cases, the best option is to replace parts, one at a time until the fault is corrected.
The intake manifold gasket may develop external engine oil leak. The manifold gasket will need to be replaced to correct this issue.
