I am reporting a safety issue involving the active handling/stability control system on my 2012 Chevrolet Corvette. After a routine oil change at grossman Chevrolet in [xxx] on xxx, the “service active handling system” warning appeared. I called the dealership and was told to cycle the ignition several times to reset it, but the warning stayed on. In early xxx, I returned for diagnosis. The dealership determined the steering angle sensor (gm part 25858802) had failed and needed replacement. I was told the part would be ordered and should arrive in about a week. After weeks with no update, I contacted the dealership. On xxx the customer service representative informed me the part was no longer available from gm. He stated the only option was to disconnect the sensor, which would leave the active handling/stability control system nonfunctional. I requested the part number and began searching for availability myself. Over the next two weeks, I conducted daily searches across gm parts suppliers, aggregators, and Corvette specialty sources. No new or nos units were available anywhere. Gm has discontinued the part without providing a replacement or superseding part number. This means the federally required stability control system cannot be repaired and the vehicle cannot be returned to safe operating condition. Gm has provided no remedy or guidance, leaving owners unable to fix a critical safety component. I request NHTSA investigate gm’s discontinuation of this essential part and determine whether a recall or mandated remedy is necessary. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
The car only has 2388 miles. Backing straight out the drive way the dash starting displaying service antilock breaks, service traction system, service active handling system. The dash lights from abs and traction stay on and the traction control control button is disabled.
Investigation number ea09-002 going into a slow left sharp turn the vehicle cut off fuel, triggered service abs, service active handling, service traction control. During this time I could not accelerate. Abs braking is now disabled and will not reset with ignition cycles.
Upon braking to enter a tight left hand turn in the country the dic displayed several warning indicators, abs and traction control. The right front brake locked up (confirmed by the flat spot on the tire). I began modulating the brakes thinking that I had lost anti-lock brakes, but the right front brake had locked up. This reduced the braking ability of the car causing me to go off the outside of a left hand turn and into a ditch damaging some components of the front end. I was able to return home safely. The car was parked until a mechanic looked at it. A dialectic grease was applied to the connectors between the system and the wheels at all 4 corners. This seemed to resolve the issue as experienced on that day. Now, 5 months later all the dash lights involved in the active handling system have come on again. Service abs, service traction control and service active handling all came on at the same time. The car will now need to return to the shop for some more diagnosing and repairs. This is a major safety issue. Having no active handling, traction control or anti-lock brakes does not make a daily drive unsafe. Not until applying brakes and you find the system locking up one wheel causing a loss of control. In an emergency situation it would be unsafe as well of course. We've come so far in improving the safety of our cars it's a shame that the same technology that improves the safety of our cars can also cause a vehicle to become unsafe.
