The anti-theft system may cause a no start condition due to electrostatic discharge (ESD) affecting the wireless control module (WCM). There is an updated WCM to correct this issue.
The carpet under the right side of the dash may become wet with water. This can be caused by the AC evaporator drain being plugged with debris. Our technicians tell us that once the drain is clear, a cabin air filter should be installed to keep debris out.
A defective vehicle speed sensor can cause problems with the cruise control and speedometer operation, as well as erratic shifting. The connectors on the sensors are also susceptible to corrosion, which will create similar symptoms. Any of these problems can cause Check Engine Light illumination.
