Known Problems

The rear wiper may stop working. This could be due to a rear wiper motor that has failed requiring replacement.

A failed heater blend door or actuator can cause the temperature control for the HVAC system to stop working. A clicking sound from the dash area would commonly indicate an actuator fault. If the heater gets stuck on the hottest setting, the heater blend door may be broken requiring replacement of the heater box to repair the issue.

4wd vehicles may develop a squealing noise coming from the front wheels when driving below 30 mph. This is generally caused by dry excluder seals, lubricating the seals will commonly correct this concern.

The intake manifold O-ring gaskets commonly leak, causing stalling and poor idle quality; the Check Engine Light will illuminate.

A rattling noise from the engine may indicate that the timing chain cassette is worn. Our technicians tell us that installing an updated cassette and timing chain tensioner should correct this concern.

The Check Engine Light will illuminate and the engine will idle roughly when cold. There are updated upper intake manifold gaskets to resolve the problem.

The rear window wiper may not fully contact the rear window. To fix, replacement of both the wiper blade and wiper arm is necessary.
