NHTSA Complaint #10139571 — 2001 CHEVROLET CORVETTE

SAME AS COMPLAINT #'S 757075 & 10124963 "ACTIVE HANDLING SYSTEM MALFUNCTION". WHILE MOVING AT SPEED (APPROX 75 MPH) IN A STRAIGHT LINE ON EVEN PAVEMENT, THE ACTIVE HANDLING SYSTEM ACTIVATES THE LEFT SIDE BRAKES HARD FOR ABOUT TWO SECONDS. THIS CAUSES MOMENTARY LOSS OF CONTROL OF THE VEHICLE. IN MY CASE THE VEHICLE DEPARTED THE RIGHT LANE AND FORCED ME ACROSS THE LEFT LANE ONTO THE SHOULDER. NO CODES. ADDITIONAL DETAIL: I ORIGINALLY TOOK THE VEHICLE IN FOR SERVICE BECAUSE I WAS GETTING A FAULT IN THE AHS, "SERVICE ACTIVE HANDLING". THE AHS WOULD AUTOMATICALLY DISABLE ITSELF AT THE TIME OF THE CODE WARNING. THIS HAPPENED ONCE PER DRIVING CYCLE WHILE MOVING AT SPEED (EXACTLY THE SAME AS ABOVE, ONLY IT DIDN'T TRY TO WRECK THE CAR). THE DEALER REFERENCED A GM SERVICE BULLETIN AND SAID THE SOFTWARE FOR THE AHS NEEDED TO BE UPGRADED. AFTER THE UPGRADE, UNDER THE SAME CIRCUMSTANCES IT NOW ACTIVATES THE AHS AND CAUSES THE VEHICLE TO VEER WILDLY. THE DEALER CAN FIND NOTHING WRONG. THIS IS A BIG SAFETY ISSUE. THE AHS SHOULD NOT BE ABLE TO CAUSE LOSS OF CONTROL. *NM
