I had this problem for a while, especially when I got into the throttle. It sounds like it can be caused by several things, but after a long time of troubleshooting (the dealer was no help) I figured out that it was caused by the voltage regulator failing on the alternator, causing frequent, high voltage spikes to the system. Replaced the alternator and all is well.

P.S. - This is the 2nd time I’ve had to replace the alternator on my 2018 ZL1 and: 1) that sucks, 2) I had a mechanic do it both times as it is in a crazy location. It’s a 5 hour job that requires removing or loosening lots from the underside of the car to access it. Way to much for me to do on my back in my garage.
