NHTSA Complaint #10409138 — 1999 BMW 328I

ON A RAINY DAY, THE TRACTION CONTROL SYSTEM ON MY 1999 BMW 328I FAILED UNDER STRESS. I DID NOT NOTICE A TURN ON A COUNTRY ROAD AND THEREFORE WENT INTO IT TOO FAST. THE TRACTION CONTROL SYSTEM FIRST PULLED ME OFF THE ROAD ONTO THE INSIDE OF THE TURN, WHERE THE VEHICLE LOST CONTROL ON THE GRAVELY SHOULDER. AT THIS POINT THE TRACTION SYSTEM MAY NOT HAVE FAILED YET. HOWEVER, I SPUN OUT LEFTWARD, AND THEN TO THE OTHER SIDE. I CROSSED ON-COMING TRAFFIC, AND GAINED CONTROL BEFORE LEAVING THE ASPHALT AND POTENTIALLY HITTING A TELEPHONE POLE. HOWEVER, ONCE I HAD THE CAR UNDER CONTROL AFTER LOSING TRACTION AND SLIDING ACROSS TRAFFIC, ALL OF A SUDDEN, THE CONTROL SYSTEM THREW ME INTO A SECOND SPIN THAT I HAD NO CONTROL OVER, AND I ENDED UP GOING BACKWARDS AGAINST TRAFFIC. THE SYSTEM WANTED TO GO BACKWARDS. I WORKED SO HARD THAT MY HANDS WERE BLEEDING AFTERWARDS. I KNOW THE SYSTEM HAD FAILED BECAUSE THE TRACTION INDICATOR LIGHT WAS ON, AND WHEN I TURNED THE ENGINE OFF AND ON AGAIN, THE TRACTION SYSTEM WOULD NOT TURN BACK ON (INDICATOR LIGHT REMAINED ON) FOR . SO THE CAUSE APPEARS TO BE A DESIGN FAILURE, NOT A MAINTENANCE PROBLEM, AND THUS REPLACING MY SYSTEM MAY NOT CORRECT THE PROBLEM. I WOULD HAVE DIED IF THERE WAS ONCOMING TRAFFIC AND THEN THE CAUSE WOULD HAVE NEVER BEEN KNOWN. SO THIS INCIDENT IS REAL, BUT MAY ONLY OCCUR UNDER STRESS. SO TO DETERMINE THE CAUSE OF FAILURE, BMW MUST TEST THE SYSTEM UNDER STRESS (I KNOW - I AM A RELIABILITY ENGINEER). BMW WILL NOT PAY TO INVESTIGATE OR REPAIR MY CAR BECAUSE THEY CLAIM THAT IT IS ONLY MY BELIEF THAT IT MALFUNCTIONED, EVEN THOUGH THEIR OWN ON-BOARD MONITORING SYSTEM DISPLAYED A FAILURE ONTO MY DASH BOARD (THE INDICATOR LIGHT). IT SEEMS TO BE "WORKING OK" NOW THOUGH (NO INDICATOR LIGHTS - SYSTEM TURNS BACK ON). IN SUMMARY, THE TRACTION CONTROL SYSTEM FAILS UNDER STRESS AND THEN TRIES TO STEER THE CAR BACKWARDS. FYI, I WAS COMPLETELY SOBER RETURNING FROM AN ATHLETIC COMPETITION, THE TIRES HAD GOOD TREAD, AND WERE INFLATED PROPERLY. *TR
