NHTSA Complaint #10416091 — 2011 BMW X3

CAR VEERING TO THE RIGHT, INCREASED ON SUDDEN STOPS; HAPPENS AT VARIOUS SPEEDS. THE PROMINENT AND DANGEROUS CONDITION IS LAG IN ACCELERATION. SENT THE FOLLOWING E-MAIL TO DEALER& BMW ALONG WITH 3 SERVICE REPORTS FROM DEALER ATTEMPTS TO ADDRESS: "THIS X3 3.5I WITH ALL IT IS ELECTRONIC ENGINE/DRIVE TRAIN CONTROLS IS A NIGHTMARE. IT?S A HUGE DESIGN FLAW THAT IS GOING TO KILL SOMEONE EVENTUALLY. YET AGAIN, YESTERDAY, I FELT UNSAFE DUE TO THE HESITATION. THE CAR DIDN'T MOVE FOR ABOUT A SECOND OR TWO WHEN I TRIED TO MAKE A LEFT TURN IN AN INTERSECTION AND THEN AGAIN WHEN I WAS ON THE HIGHWAY CHANGING LANES. THERE WERE CARS HEADING TOWARDS ME BUT THE INITIAL DISTANCE WAS QUITE COMFORTABLE AND SAFE. WITH THE HESITATION OF THE X3, I WAS ACTUALLY IN A PANIC AND STEPPED REALLY HARD ON THE GAS PEDAL TO AVOID A POTENTIAL COLLISION. AND SINCE THEN I HAVE BEEN STEPPING ON THE GAS PEDAL MUCH HARDER, GUZZLING GAS, NOT TO MENTION ROUGH STARTS OFF OF A FULL STOP. I HAVE SEEN COUNTLESS INTERNET THREADS OF PEOPLE COMPLAINING ABOUT THE SAME THING WITH THE X3 MODEL, BOTH VERSIONS, HOWEVER EQUIPPED. I WOULD STRONGLY SUGGEST SOMEONE LOOK AT HOW THIS CAR?S SOFTWARE IS FAILING TO FUNCTION AND FIX THIS THING. I WILL REPORT THE PROBLEM TO THE APPROPRIATE GOVERNMENTAL AGENCIES. THE VEERING IS STILL THERE AND EVENTUALLY I WILL COME TO PASS THE ISSUE WITH THE LOW TREAD LIFE RUN-FLATS BMW'S 2-23-11 VISIT, DEALER ALIGNED VEHICLE, KEPT CAR ONE DAY DUE TO FACTORY SPECS NOT YET BEING LOADED ON NEW VEHICLE MODEL; ON 7-13-11, DEALER NOTED CAR LEFT IN TRANSPORT MODE, REMOVED CODES FROM COMPUTER SOFTWARE AND CAR DROVE OK FOR 4 DAYS; 7-23-11 TOOK IT BACK FOR SAME ISSUE AS NOTED ABOVE WITH LAG IN ACCELERATION BECOMING DANGEROUS AND STILL VEERING, THIS TIME DEALER NOTED NOTHING WRONG WITH CAR AFTER TEST DRIVE COMPARISON. GAVE CAR BACK, STILL HAVE ISSUES WHICH PROMPTED E-MAIL.
