If a clunking or "loose lumber" noise is coming from the front or rear suspension, there are revised shock absorbers available that can help the concern. This is usually heard at lower speeds and colder temperatures when driving over bumps.
The thermostat may fail to close completely, causing the Check Engine Light to illuminate. This problem will prevent the engine from reaching normal operating temperature; a new thermostat should be installed.
If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.
Engine overheating can result from coolant leaks which are commonly found at the thermostat housing gasket, water pump, heater return tube O-ring at the water pump, intake manifold gasket, and timing cover gasket. Our technicians recommend a complete inspection of the cooling system after any repairs are made to be sure there are no other leaks.
A software issue with the sunroof module may lead to a battery drain while the ignition is off. This may cause a dead battery if the vehicle is left parked for a couple days, however reprogramming the sunroof module with new software may fix this problem.
On some models a void in the rear window seal may cause a water leak. Water may be present on or under the carpet. The seal will need to be replaced if that is the source.
If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.
