It was a life-threatening situation where we were virtual sitting…

My 2020 Porsche Taycan 4S (VIN [XXX]) has a recurring, dangerous brake failure that remains unresolved after multiple dealer repair attempts. At low speed, the automatic emergency braking system activates on its own and begins decelerating the car. As the car slows to roughly 5 mph, the brake pedal drops, braking pressure disappears, and the vehicle keeps rolling forward. Pressing the pedal as hard as I physically can does not bring the car to a stop. On more than 5 occasions I have had to…
