NHTSA Complaint #11668584 — 2021 CHEVROLET EQUINOX

I was driving my vehicle and went to make a left turn out of a parking lot into traffic and my engine shut off and my car rolled into traffic and the check engine light turned on. All of the other functions in the car stayed on i.e. radio, air and all the lights. I had to have the car towed to a mechanic the mechanic was unable to diagnose my car so it was then brought to a chevy dealership. The dealership stated my car worked fine with no issues and tried to return the vehicle back to me I insisted they keep testing the vehicle. They drove the vehicle around the parking lot again in circles and the cars engine shut off and is unable to be turned back on. GM and CHEVY are stating they have no idea why this is happening. I am very concerned about this considering they tried to return the vehicle to me stating their were no issues and ignoring my concerns at first, I had to insist that they keep checking the vehicle and now it will not even turn on.
