Did you have a throttle controller installed?

"Make sure you have adequate insurance." Driving a car that unexpectedly revs to the redline, I'd say that's a pretty good comment/suggestion/caveat/reminder, actually.

I kept my foot on the clutch but it freaked me out as my right foot was not on the throttle. I shifted back to neutral and turned off the car. I restarted it and it was fine. No codes. It happened a second time a few days later, but has been fine ever since.

No TC, but I've had a similar occurrence on my 2019 recently pulling into the garage twice now. No codes, and yes it is unnerving.

The first C7 I had, a 2015, did odd things like that every now and then. Once, the dash wouldn’t come on until I stopped the car and restarted the engine. Never happened again.
