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

On 9/18/2025, while driving at approximately 45 mph on a busy road called Hualapai in Las Vegas, Nevada, my Porsche Taycan suddenly displayed “Electrical system error – Park vehicle in a safe place”. The car immediately slammed to a stop in live traffic. I heard a loud thump from the front end as this occurred. I was nearly hit by six cars swerving to avoid me in the rain. Gladly no one made contact and no one was hurt. My car turned into a brick in the middle lane with lots of traffic sort of like I brake checked them all. I lost all steering as it locked up, I couldn't get out of fast moving traffic as the car wouldn't go back into drive and had to toggle to neutral and push the car. This was a life-threatening failure that created a dangerous hazard for me and other drivers.

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.

When the car was in Drive (D) mode but stationary at a red light, it abruptly went in to park (P) without any user intervention. Had to reengage the drive mode to move forward. Problem has occurred at least twice before (months apart) without any reproducibility. I did bring it to the dealer once but they did not find any abnormal logs. Latest occurrence on 7/6/2022 at approximately 6:15 PM Lost power steering assist completely in my driveway while backing out of the garage in reverse mode. No warning signs on the cluster. Could not turn the car. Only way to get power steering assist back was to turn off the car completely, wait for 10 seconds and turn it back on again. Incident happened on 7/7/2022 at 7:45 AM
