On several occasions, the car has slammed on the brakes with no obstacle in front of or behind the car. Sometimes it happens when in reverse, while other times while going forward. The car is seeing things that aren't there and slamming on the brakes. Recently it happened while making a turn and the driver behind me almost rear-ended me. I was going forward with no obstacle in front of me. He was going forward at a reasonable distance behind me. It has happened several times in my driveway while backing out with no obstruction behind me.

While driving at about 60 mph on highway, several systems in the car failed without prior warning. The message on dashboard said Catastrophic Electric System Failure. Brakes would not work for a moment and then started working. All windows came down and went up on their own. No lights were working. No blinkers or side lights were working. With a lot of difficulty and hand signals moved to the hard shoulder. The engine would not turn off for several minutes and turned off after multiple attempts. Audi tested the vehicle and found multiple DTC's in various modules - all sporadic and happened at the same time. Audi did software update and is waiting for another software update to be approved by EPA. The Director of Service at Audi thinks the failure may be also due to a problem with hardware/battery. He said he does not trust the vehicle in its current state and the vehicle is presently grounded at the dealership.
