Electrical switches in the door latches can fail, causing the door locks to rapidly actuate up and down multiple times when the locks are activated by either the keyless remote or door lock switch. The affected door latch should be replaced to correct this concern.
The electrical connector at the automatic transmission may leak fluid. Over time leaking fluid could migrate through the wiring harness and damage the transmission control module. If that happens a new harness and control module may be necessary to correct the problem.
The power window switch may fail and the windows will not raise. The main switch at the front center console is commonly at fault. A failed switch will require replacement.
A no start condition may develop due to an anti-theft system fault. If the drive authorization module fails to recognize the keys, the engine will not start. In many cases, a new module and keys will be needed to correct this problem.
The door storage pocket can become unglued and fall into the door.
The covering for the center console can bubble and discolor. Replacement of the affected part is most commonly only way to repair this concern.
Various electrical problem may develop due to a failed "all activity module". Our technicians tell us that proper diagnoses is required to be sure any electrical faults are being caused by the failed module.
The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern. A recall on certain 2000-2001 models have been recalled for a related issue - for more information please click here»
The crankshaft position sensor may fail causing the engine to stall. In most cases the engine will need to cool down a bit before it will restart but in some cases it may restart right away.
As the spark plug wires age and are exposed to heat cycling, they start to develop micro cracks in the insulation around the resistors, which causes misfires and poor fuel economy.
Leaks may develop from the differential cover and/or seals on high mileage or older vehicles. Our technicians recommend a complete reseal of the differential unit if these leaks are addressed.
