NHTSA complaint #11607065

Owner complaint summary

Car has collision detection and remedy system that detects for impending collision and activates braking. Incident occurred when the car in front abruptly brakes and my car detected collision and applied brakes, however, the brakes were not fully applied and would not completely stop to avoid colliding with the rear end of the car. Most importantly, the car would not respond to me pushing the brakes. I tried a couple of times in the short time before I had to turn into the next lane to evade collision. Luckily there were no car next to me. Also the pedal sometimes need to be pressed hard for the brakes to work effectively, and feel the brakes are soft. This happened a few times and both instances were reported to Porsche dealer. This is very dangerous as it occurs when you least expect, and leaves no error code. Dealer found the pedals to be ‘soft’ and adjusted but brake fading issue still persist. This car is a death trap with many recalls including battery bricking on the highway rendering the car immobile in the middle of traffic. Porsche should be forced to buy the car back.
