I was told the 30 second wrench light was due to the cruise control not working correctly? It is currently at the dealer for a cruise control fix - parts were ordered.
Also the car has several error codes that will not clear - mainly cylinder misfire codes.
It temporarily generates a variety of error codes (check engine light, wrench, transmission solenoid, etc., etc.) whenever it is washed. I told them this has to be corrected, else it will not pass E-Check.
I'm keeping my fingers crossed.
Moisture working its way into the ECU sounds like a possibility?
