My car shut off two times while driving. When you google the issue, it auto populates meaning that this is a very common issue with GM. It starts back to 2015 searches as well. GM needs to recall their suburbans for their cars turning off while driving which caused me to lose power steering, power brakes and anything that requires electrical.

2020 Chevrolet Suburban. Upon vehicle start: Steering assist, trailer brake system, stability track all inop. Tachometer and speedometer inop. No reverse gear. When in drive, only first gear obtainable and manual shift mode inop. Seat heat inop. Turned off and restarted approx five times and issues remained. Upon sixth restart issues no longer present. Drove 15 miles home. Vehicle sat 2 hours, then restarted and operated normally for 1/2 hour operation, then turned off. Vehicle operated normally twice within two hour period. Parked overnight, and in a.M. remote started Suburban and issues present again. Turning offf and restarting approximately 10 times did not resolve issue. Turning ignition off and then turning to 'on'( but not starting ) shows warnings as well. Attempted 10 times to "run" position with no change. After sitting for 15 min, vehicle started normally and drove to dealership. 816 miles total on vehicle.
