While in "race" mode, if I go into the infotainment and select "safety", then go to "Lane departure warning", I can brick the system.
The car must be fully shutoff then restarted to reboot the infotainment.
Dealer says the software patch is available. They would need the car for at least two days. The word is that all of the modules must be asleep in the car in order for the update to start.
What is your VIN range and software version(s)? Does your infotainment lock-up as well?
