Stability control Vehicle recall #22V239000 · 2022 · 458,110 vehicles
What's wrong: The skid control ECU software May not turn on the vehicle stability control (vsc) system when the vehicle is restarted after the driver has disabled the vsc system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 126, "electronic stability control systems."
Why it matters: Driving with a deactivated stability control system increases the risk of a crash.
The fix: Dealers will update the skid control ECU software, free of charge. Owner notification letters were mailed May 27, 2022.
