NHTSA Complaint #10519679 — 2007 BMW 530I

I'M AN OWNER OF THE BMW530I & AROUND THE END OF APRIL I BEGAN TO FEEL A JERK TYPE OF MOTION (A SLIGHT ACCELERATION) WHEN I CAME TO A STOP . I CALLED THE DEALER WHO ASKED IF THEY COULD TEST DRIVE IT BECAUSE THEY CANNOT EXPLAIN WHAT THAT COULD BE . ON 5/30/2013 I TOOK THE CAR INTO THE DEALER & I WAS TOLD THE CAR MAY JUST NEED TO BE UPDATED BECAUSE THEY COULD NOT EXPLAIN WHAT WAS CAUSING THE JERKING MOTION UPON STOPPING . AFTER ABOUT 1 HR 1/2 I WAS TOLD THEY NEEDED ME TO GIVE THEM AUTHORIZATION TO PUSH PASS THERE SYSTEM BECAUSE FOR SOME UNKNOWN REASON THERE SYSTEM KEEPS STOPPING/UNABLE TO DIAGNOSE & THE TECH SAYS THEY TRIED SEVERAL TIMES & IF THEY CONTINUED IT COULD POSSIBLY BLOW MY ELECTRICAL OR RADIO SYSTEM , THEY WOULD NOT TAKE THE RESPONSIBILITY . I COULD NOT TAKE THAT CHANCE BECAUSE THAT IS THE ONLY VEHICLE MY SELF & FAMILY HAS . SO AT THAT POINT THE TECH & THE SERVICE MGR EXPLAINED THAT THERE WAS NOTHING ELSE THEY COULD DO & THEY FELT IT WAS STILL A SAFE VEHICLE TO DRIVE . BMW SHOULD BE ABLE TO DIAGNOSE THERE OWN VEHICLES & IS THIS A MANUFACTURERS DEFECT ? I AM VERY DISAPPOINTED & CONCERNED ABOUT THE SAFETY & SECURITY OF MY SELF & MY CHILDREN . *TR
