Two problems related to engine failure have been reported for the 2011 BMW M3. The most recently reported issues are listed below.
I was driving casually when the motor suddenly shut off. No noise indicating engine failure ever happened. I coasted off the road and tried to restart. Nothing but a click. Eventually tried replacing starter motor but that didn't work. No engine lights or codes ever popped up. Turns out engine seized due to failed rod bearings.
I was driving in queens mid town tunnel, suddenly my engine stalled and the car would not start again. It was a two lane tunnel, my car was blocking one lane of traffic. Called nypd to have the car towed to a safe location. According to the dealer of park Ave BMW. They think its a engine failure.
