NHTSA Complaint #11080383 — 2011 BMW X5 SAV

DURING HARD ACCELERATION OF THE CAR WHILE GETTING ON THE FREE WAY RAMP, THE CAR WENT INTO LIMP MODE. THE ENGINE PERFORMANCE WAS DEGRADED AND I HAD TO PULL ON THE SIDE OF THE ROAD TO RESTART THE CAR. THE CAR WAS TAKEN TO BMW OF BELLEVUE NEXT WEEK AFTER INITIAL DIAGNOSIS OF A DME INTERNAL FAULT BY A SIGNATURE INDEPENDENT KIRKLAND. BMW OF BELLEVUE REPLACED AIR MASS FILTER AND OIL FILLER CAP. A FEW WEEKS LATER THE ISSUE HAPPENING AGAIN DURING REGULAR DRIVING ON THE FREEWAY. BMW OF BELLEVUE DIAGNOSED THIS AS A VACUUM HOSE LEAK. A FEW WEEKS LATER THE CAR WENT INTO LIMP MODE AGAIN WHILE GETTING ON THE FREEWAY, BMW OF BELLEVUE DIAGNOSED THIS AS A HIGH PRESSURE FUEL SENSOR SHORT, BMW OF NORTH AMERICA OPENED A PUMA CASE, BUT DID NOT RECOMMEND REPLACING THE DME YET. RIGHT AFTER PICKING UP THE CAR I HIT THE ISSUE AGAIN WHERE THE CAR WENT INTO LIMP MODE WHILE ACCELERATING ON THE FREEWAY RAMP. BMW OF BELLEVUE WORKED WITH BMW OF NA TO REPLACE THE DME WHICH IS COVERED UNDER WARRANTY. BEFORE HANDING THE CAR BACK THE SERVICE ADVISOR DID A TEST AND WAS ABLE TO STILL REPRODUCE THE CAR GOING INTO LIMP MODE GETTING ON THE FREEWAY, DIAGNOSIS IS STILL NOT KNOWN. IT HAS BEEN 3 MONTHS TODAY SINCE THE ISSUE FIRST HAPPENED AND THE CAR HAS BEEN OUT OF USE FOR MORE THAN A MONTH AND THERE IS STILL NO CONCLUSION ON THE ROOT CAUSE.
