NHTSA Complaint #11460179 — 2020 BUICK ENCORE GX

While driving this 2020 Buick Encore GX with around 7,000 miles on the odometer, the entire electrical/electronic system shut down. Windows were inoperative, the AC stopped, the radio failed, the flashers did not work, etc. The only things that worked were the engine and brakes. I have no idea if the brake lights worked. I was able to drive the car to the dealership - Van Buick GMC in Scottsdale, Arizona where the car is now sitting and awaiting their inspection. In the 95 degree temperature here in AZ, I thought that I would die as I could not open the doors. I have since learned that I could have opened the doors by pulling the door handle twice. No one ever educated me on this. There were no advance warnings prior to the failure. This car is a death trap. Please NHTSA help me.
