NHTSA Complaint #11128224 — 2012 BMW 528I

THE CAR FRONT AND REAR TIRES WERE OF DIFFERENT SIZE AND I NOTICED WHEN I GOT THE CAR FROM DEALER NEXT DAY AS THE CAR WOULD DRIFT TOWARDS ONE SIDE. IT GAVE "DRIVETRAIN ERROR" SINCE ITS ALL WHEEL DRIVE WITH POWER NOT BEING EQUALLY DISTRIBUTED DUE TO DIFFERENT RPM ON FRONT AND REAR. THIS WASN'T THE CASE WHEN I TEST DROVE THE DAY BEFORE. I KEPT THINKING ITS A TRANSMISSION ISSUE BUT IT WAS TIRE THAT WAS CAUSING IT. AT HIGH SPEED (40-60MPH) WHEN I TAKE OFF FROM GAS THE CAR WOULD DRIFT TO ONE SIDE AND WOULD STALL. THIS IS SERIOUS SAFETY ISSUE AND COULD HAVE CAUSED NOT ONLY PASSENGER LIFE BUT ALSO MAJOR TRANSMISSION AND DRIVETRAIN BREAKDOWN. THE DEALER SWAPPED THE TIRES BECAUSE WITH MISMATCHED TIRES THE CAR WOULD HAVE BEEN NON-DRIVABLE AT THE TIME I BOUGHT. THIS AWD IS VERY SENSITIVE TO TIRES TREAD DIFFERENCES. AFTER CALLING DEALER HE IS DENYING AND SAYING ITS "AS-IS" AND NOT RESPONSIBLE FOR ANYTHING.
