Hello, long time lurker here and first time poster. Got a problem with my 2010 Nox V6 2LT. We purchased the car last March and have driven it without any problems until this Monday. Started the car to warm up and after a couple of minutes the door locks went crazy (locking and unlocking). Then the DIC showed service stablitrac and service rear parking assist. I shut the car down and waited an hour, started it again and same message came up plus the check engine light was on.
I called OnStar to do a diagnostic and they said something wrong with the TCM not communicating with the ECM. They asked me to shift the gear selector and see if the DIC shows what gear is selected. No gear selection comes up on the DIC, i also tried to rev the engine and no throttle response. They said it has to be towed to the dealer for further diagnosis and they arranged for the towing. While waiting for the tow I decided to empty the car and tried to open the rear lift gate to get my stuff out but the liftgate wouldn't open (arggh).
Once at the dealer they called me and said a TCM switch has gone bad and thats the cause of all the other malfunctions including the liftgate. They also told me that the part should arrive in 3 days or by Wednesday. Today is the 5th day and still no TCM switch. This situation is getting frustrating. I hope they get the part soon!
Has anyone expereinced this problem? And how long have you waited for the part?
