The problem only occurs when it is raining or when there is wet snow or after I have a car wash. Nothing seems affected the vehicle works fine, and after the car drys up the message disappears.
2007 SRX, when the roads are wet the "Service Quadratrac" Light comes on. on 2007 Cadillac SRX
Sounds like there may be a wiring issue such as insulation rubbed through or water getting in conector.
