Two problems related to engine and engine cooling have been reported for the 2009 Chevrolet Avalanche. The most recently reported issues are listed below.
Engine dies, door locks start opening and closing, all dash lights go off, radio goes off,car starts on own 3 to 6 seconds, did this at 60 mph and at 15 mph.
Episodically when ignition key switch is engaged it will stick and cause the starting motor to remain engaged requiring turning the switch back to off position then trying to restart the vehicle. Being careful not to hold the ignition switch key in the position necessary to engage the starter any longer than absolutely necessary to hear the engine fire then returning the key position to the run position seems to prevent the problem.
