NHTSA Complaint #11024588 — 2016 BMW X3

MAY 31, WHILE SLOWING TO ENTER A TOLL BOOTH, ENGINE STARTED REVVING UNCONTROLLABLY, MAINTAINING EXCESSIVE SPEED. I BRAKED HARD AND VEHICLE STOPPED IN TIME TO AVOID A COLLISION. VEHICLE OPERATED NORMALLY THEREAFTER UNTIL AUGUST 27, WHEN, STOPPED AT A TRAFFIC LIGHT ON A HIGHWAY, ENGINE AGAIN STARTED REVVING, RANGING FROM ABOUT 3500 TO 4000 RPM. I SHIFTED TO PARK AND ENGINE IMMEDIATELY REVVED UP TO OVER 7000, IN RED ZONE OF TACHOMETER. REVVING STOPPED AFTER A MINUTE OR SO AND VEHICLE OPERATED NORMALLY. THE NEXT DAY, I HAD VEHICLE TOWED TO BMW ROCKVILLE. SERVICE DEPARTMENT EXAMINED VEHICLE AND FOUND NO DEFECTS, SUGGESTING POSSIBILITY THAT DRIVER MAY HAVE HAD FOOT ON BRAKE AND ACCELERATOR AT SAME TIME. I DID NOT THINK SO, ESPECIALLY AS THIS HAD NEVER HAPPENED BEFORE AND REVVING WAS UP AND DOWN, REQUIRING RHYTHMIC ACTION ON GAS WHILE HOLDING BRAKE DOWN FIRMLY. AS WIFE AND I DID NOT FEEL SAFE DRIVING THE CAR, WE HAD ALSO ALERTED BMW NORTH AMERICA, WHICH SENT AN ENGINEER TO TEST THE VEHICLE. BMW NA'S ANALYSIS FOUND NO DEFECTS BUT OFFERED TO HELP AS WE WISHED TO TRADE IN THE CAR. IT WAS TRADED IN TO BMW ROCKVILLE SEPT 17, AT CONSIDERABLE FINANCIAL LOSS. I HAVE A COPY OF BMW NA'S REPORT, BUT IT SHOWS ONLY THAT THE CAR IS IN PERFECT OPERATING CONDITION. BMW ROCKVILLE SALESMAN SAID VEHICLE WOULD NOT BE RESOLD, BUT WOULD BE CANNIBALIZED FOR SPARE PARTS.
