2001 BMW 3 SERIES Electronic Stability Control Esc Problems

WHILE DRIVING ABOUT 70 MPH IN A STRAIGHT LINE ON THE HIGHWAY, THE DYNAMIC STABILITY CONTROL LIGHT TURNED ON AND THE CAR JERKED AND STUTTERED ALMOST AS IF IT WAS BRAKING ON ITS OWN OR LOCKING UP. THIS OCCURRED TWICE TODAY AND IS A SIGNIFICANT SAFETY ISSUE AS IT WAS UNEXPECTED AND COULD HAVE LED TO A LOSS OF CONTROL, WHILE DRIVING AT A SIGNIFICANT SPEED ON THE INTERSTATE. BMW SHOULD HAVE TO DO SOMETHING ABOUT WHATEVER IS CAUSING THIS PROBLEM.

THE "YAW SENSOR" FAILS IN THESE CARS, FREQUENTLY CAUSING A SUDDEN BRAKING ON ONE SIDE OF THE CAR AND PULLING THE CAR IN THAT DIRECTION. THIS IS A REAL HAZARD: THE CAR SUDDENLY BRAKES BY ITSELF WITHOUT WARNING. THE PROBLEM IS WELL DESCRIBED IN THESE DISCUSSION FORUMS: HTTP://WWW.M3FORUM.NET/M3FORUM/ARCHIVE/INDEX.PHP/T-450191.HTML HTTP://WWW.BIMMERFORUMS.COM/FORUM/SHOWTHREAD.PHP?1022059-LATERAL-ACCELERATION-SENSOR-FAILURE THE ORIGINAL SENSORS FOR THIS CAR WERE DISCONTINUED AND THE ONLY REPLACEMENT PART AVAILABLE IS FOUR TO FIVE TIMES THE PRICE OF THE ORIGINAL PART -- OVER $1000. THIS HAS LED TO A MARKET IN USED SENSORS THAT ARE ALSO IN DANGER OF FAILING. THIS IS A REAL HAZARD. *TR
