NHTSA Complaint #10653661 — 2007 BMW X5 SAV

IT WAS 9:57A.M. SATURDAY, NOVEMBER 8TH 2014, STARTED DRIVING THE VEHICLE, AND NOTICED THAT THE WHOLE DRIVE TRAIN WOULD SLIGHTLY JERK WHILE DRIVING AND APPLYING 15-25% OF LOAD, (I BOUGHT A VEHICLE TWO MONTHS AGO, AND FROM THE FIRST DAY - ON COLD - IT WOULD MAKE THE SAME SYMPTOM FOR COUPLE OF FIRST 500-700 YARDS, AFTER COUPLE OF STOPS AND GOES, VEHICLE HEATS UP TO OPERATING TEMPERATURE AND THE VEHICLE WOULD DRIVE NORMALLY.) AT 10:20A.M, SAME SATURDAY, I MADE A FULL STOP ON A STOP SIGN TURNING RIGHT TO A MAIN STREET. AS MOST OF THE TRAFFIC WAS DRIVING ON THE MAIN STREET, I WAITED FOR THE FAST PAS PACED TRAFFIC TO PASS BY, I TRIED TO ENTER THE MAIN STREET BY ACCELERATING THE VEHICLE. SO I APPLIED APPROX. 20-25% LOAD, IT WAS 5MPH WHEN I WAS ABOUT TO ALIGN STEERING WHEEL TO ZERO DEGREES CENTER, I HEARD AND FELT REAR SUSPENSION FREEZING UP, CLICKING AND CHATTERING WITH LOUD GRINDING SOUND (SOUNDED LIKE THE AXLE FELL OUT) ENGINE RPM WOULD INCREASE TO 3,000RPM BUT VEHICLE WOULD NOT ACCELERATE, AND SOMETHING IN THE REAR WAS STILL GRINDING WHEN TRANSMISSION WAS IN DRIVE OR REVERSE. I HAD TO PULL OVER TO THE CURB, BLOCKING RIGHT LANE. VEHICLE HAD NO TRANSMISSION WARNING LIGHTS OR ERROR MESSAGES ON CLUSTER. I DID TOWED THE VEHICLE TO MY BMW TECHNICIAN, AND HE TOLD ME THAT I NEED REAR DIFFERENTIAL, REASON INTERNAL FAILURE, I TOLD TECHNICIAN TO MAKE NOTES OF ANYTHING UNUSUAL WHILE TAKING REAR DIFFERENTIAL OUT OF THE VEHICLE. TECHNICIAN NOTED THAT REAR DIFFERENTIAL FLUID WAS RIGHT AT ITS LEVEL AND NO LEAKS OR EVEN SEEPAGE WAS NOT NOTICEABLE (I OWNED MANY BMWS WELL OVER 200K MILES ON THE CLUSTER, AND HAD NO ISSUES WITH REAR DIFFERENTIALS.)
