NHTSA Complaint #11459128 — 2017 CHEVROLET VOLT

My car, like many other 2nd Gen Volts, experienced a BECM failure that resulted in two events where the car unexpectedly lost all propulsion power and came to an uncontrolled stop. I believe the electric power steering was also disabled in both events. Luckily these events both occurred at low speeds, not on a crowded highway, as I do not believe this failure would allow the driver to get to the shoulder. The car was immobilized after both events and needed to be reset to drive home in a 'reduced propulsion' limp mode. There were not, to my knowledge, any warnings, CELs, etc. before the first event. The car has been with the local Chevy dealership for over two months waiting on part availability, as this is a common failure. It appears from online discussion that this is extremely common on this year and make.
