2017 Chevrolet Equinox drivetrain & axles problems

Tl* the contact owns a 2017 chevrolet equinox. The contact stated that when the gear selector was used to shift into drive or reverse, the vehicle kept rolling in reverse as the gear failed to remain in position. The dealers were unable to replicate and diagnose the failure. The manufacturer was notified of the failure and opened a case. The manufacturer did not provide further testing to assist the dealer and closed the case with no remedy provided. The VIN and failure mileage were not available.

I was on the expressway and was going around a curve and noticed that my power decreased and felt like my car was not moving as fast. I looked and the check engine light on my dash was on and it said engine power reduced, and the 2nd screen said to check stabilitrak. I got off at the next exit and pulled right into a parking lot. When I turned off the vehicle and turned it back on it still had the check engine light on, but the service stabilitrak was off.
