ENGINE FAILURE (WITH ONLY 60K MILES ON IT) WHILE DRIVING AT 70MPH WITHIN MINUTES OF WARNING LIGHT SAYING 'DRIVETRAIN MALFUNCTION'. THE ENGINE SHUT OFF, CAR WENT INTO NEUTRAL AND I HAD TO MANUALLY STEER AND BRAKE TO GET TO THE SIDE OF THE FREEWAY. WITHIN MINUTES, THE BATTERY DIED, SO I COULDN'T EVEN PUT THE CAR INTO NEUTRAL TO GET IT ONTO THE FLATBED TOW TRUCK. I EVENTUALLY WAS ABLE TO GET IT TOWED TO THE DEALER WHERE I BOUGHT IT CPO IN 2015 AND HAVE HAD IT SERVICED (I HAD EVEN HAD IT SERVICED THERE 3 WEEKS BEFORE THIS INCIDENT). THE ENGINE HAD RECEIVED THE "CUSTOMER CARE PACKAGE" IN 2015, AND I'VE ONLY HAD IT SERVICED THROUGH BMW DEALERS. 3 DAYS AFTER I HAD THE CAR TOWED TO THE DEALER, THE SA TOLD ME THERE WAS A COMPLETE ENGINE FAILURE AND THEY WOULD REPLACE THE ENGINE. IT'S BEEN THERE FOR 4 MONTHS NOW, WAITING FOR A NEW ENGINE, AND THE MANAGER OF THE SERVICE DEPARTMENT CAN'T PROVIDE AN ESTIMATE ON WHEN THE NEW ENGINE WILL ARRIVE. I CONTACTED BMW NA, AND THEY WERE ALSO UNABLE TO TELL ME WHEN A REPLACEMENT ENGINE COULD BE EXPECTED. I'M NOT EVEN SURE I WANT A REPLACEMENT ENGINE THAT HAS THE POTENTIAL TO FAIL AGAIN.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2012 BMW 750xi verdict →
