What 78 owners told NHTSA about the 2022 Porsche Taycan Turbo S

My Porsche Taycan unexpectedly applies the brakes on its own while traveling at highway speeds and flashes a red warning message instructing me to take control of the steering wheel, even though both of my hands are already on the wheel. This is extremely dangerous because sudden braking at high speeds creates a major risk of rear-end collisions and loss of control. When It Occurs: This issue started recently and has happened multiple times under normal driving conditions (clear weather, open road, both hands on the wheel, no imminent obstacle). It appears to occur without warning and without any legitimate reason for emergency braking. Approximately 3 times in 1 month. Dealer Response: I reported the problem to my Porsche dealership. They claimed this behavior is “normal,” but also acknowledged that many other owners have experienced similar issues. Despite this, they offered no fix and did not classify it as a defect. I strongly disagree that this is normal—this is a critical safety hazard. I have another upcoming appointment for an additional check June 29, 2025. Safety Risk: Unexpected braking at highway speeds could lead to a rear-end crash, loss of control, or serious injury. This is not driver error. The vehicle is misinterpreting conditions or malfunctioning, and the warning to take control of the steering wheel despite both hands being on the wheel suggests a possible sensor or software failure.

The Porsche Taycan's brakes have always been soft. Recently, at slow speeds, I have had to pump the brakes to stop. The last time, I had to turn off the road to prevent an accident. The tow truck driver, who brought my car to Englewood NJ Porsche stated I had no brakes. Porsche of Englewood called me after their evaluation stating the car was fine and could not find a brake problem. I told him that the internet had multiple complaints that the Taycan brakes would not work at slow speeds and that it was found to be the brake booster that was malfunctioning. I am not the only person to experience this. Please look into this problem. [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There was a different amount of pressure needed to apply to the break when at lower speeds vs higher speeds. At lower speeds there was less responsiveness to the breaks and more pressure was required to stop the car. We brought the car to the dealer and dealer reported the car was fine. The problem persisted and an error message came on that said "break fluid low- bring to dealer". The car was brought into dealer again and the dealer flushed the break system and put new fluid in. The problem continued to persist and the dealer replaced the break booster fixing this issue. Our safety was at risk because the breaks were malfunctioning.
