One problem related to engine shut off without warning has been reported for the 2012 Chevrolet Suburban. The most recently reported issues are listed below.
While just starting to accelerate, the radio shut off, the automatic locks started to go up and down, then the engine light came on and the engine stopped running. I put the truck in park, shut of the engine and restarted without issue 5 minutes later. Two days later, the same thing happened, only this time, when we went to restart the truck, it seemed as though the battery was dead as no dome lights would come on and the fob would not work the door locks. 3 hours later when the tow truck operator showed up, the truck started right up. This has happened 5 times since April 6th. The last time, the engine shut off as I was crossing a four lane highway. Luckily, we were not hit. Seeing multiple reports of the same issue make me think it is not unique to my vehicle. "dead battery" that isn't dead. . . "locks going up and down", "sudden deceleration". Does someone have to have an accident and be killed for anyone to take action on this issue?? why not be proactive and start investigation before someone gets killed??.
