STEERING,ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL — Filed 06/28/2023

In June of 2023 I was driving my vehicle and suddenly the Traction Control, power steering and check engine light came on. I was able to get the vehicle safely home without the use of the power steering. Once I shut the vehicle off, it would not start again. I got the vehicle to my local dealership and they diagnosed it as one of the main wire harnesses was rubbing against a bolt near the battery, which is a known issue, and caused an electrical short in the system. It caused the ECU and electronic power steering to short out. They replaced the ECU, but have not been able to replace the eletronic power steering because it's no longer being manufactured. The vehicle at the time of incident was only 6 years old. I feel like this is a violation of the Magnuson-Moss Act. There are no third party vendors that make this part. It has only ever been available through GM directly.
