2022 Porsche Taycan Fuel system Problems

I am reporting a safety defect involving (1) sudden loss of propulsion (“turtle mode”/limp mode) while accelerating/merging into traffic and (2) unintended steering movement while driver-assist/lane centering was active (vehicle jerked toward adjacent lane and off roadway). These events create an immediate crash risk. The vehicle has also had repeated charging-related overheating/charging stoppage events, which I believe may present a fire risk when charging in a residential garage. Repairs have been attempted multiple times by an authorized Porsche dealer, but defects persist. Warranty has now expired, and an independent scan shows ongoing network/data bus/12V monitoring faults consistent with continuing electrical/network instability. I am requesting NHTSA review for a potential safety defect investigation/recall.

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.

NHTSA campaign 24V732000 is a recall of 27,000 Porsche Taycans for high-voltage batteries may short circuit and increase risk of fire. For vehicles in Porsche campaign ARB6 for which online data is unavailable, owners are advised to have the recalled vehicles inspected and limit charging to 80%. In December 3, 2024, letter (attached) to UK Taycan owners of Taycans in ARB6, in addition to limiting charge to 80%, Porsche writes: “Additionally, until the inspection has been completed, we would advise not to charge the vehicle under cover and or to ensure the vehicle is not parked adjacent to or under buildings.” Why is Porsche’s warning to UK Taycan owners in ARB6 not to charge their Taycans under cover and ensure the vehicle not parked adjacent to buildings not included in the ARB6 notification letter to US Taycan owners?

While driving on the city streets, the vehicle would not accelerate properly. At a stop sign, when pressing the accelerator, the vehicle started to jerk forward slowly and would not accelerate properly. A turtle started to flash on the cluster display. Trying to get to a safe location, the vehicle kept jerking forward slowly while slowly increasing speed and flashing the turtle icon.

While driving on the freeway at 65 mph, the vehicle suddenly began to quickly decelerate. Pressing the accelerator pedal had no effect. The car behind me quickly swerved to avoid hitting me. I was able to maneuver the car onto the shoulder and very slowly exited the freeway. I noticed a warning light shaped like a turtle on the cluster display flashing. I stopped fully and turned off the vehicle. The car was then towed to the nearest Porsche dealer. One week later, the dealer was inspected the vehicle and was unable to reproduce the issue. No repair was performed and Car was returned.

On 3/26/23 my 2022 Porsche Taycan Turbo self-ignited in our garage and created a lithium fire literally incinerating itself and completely destroying 3 other cars, the garage and approximately 35% of our home. The resulting fire filled the home with smoke, soot and required us to leave the house immediately and we have yet to return. The car was not being charged at the time of the fire; the charging unit was stored in the truck anticipating the dealership's promise to pick up the car for repair (again) the very next day. It was a four alarm fire supervised by the Bloomfield Township Fire Department and Oakland County Sheriff's Department. My wife and daughter personally witnessed the origin of the fire. The flames came from the bottom of the driver's side wrapping over the top of the Porsche and igniting the garage and the other cars. All cars were a complete loss. The Porsche Taycan was originally purchased new on 9/30/22 and was in and out of the dealership starting 2/9/23. The Service History is attached herein.

Without warning the car flashed an "Electrical Failure" warning and then lost all power and coasted to a stop while "bucking" slightly. This stranded us on the side of a narrow 2-lane road (NV28) with limited visibility. The high-voltage battery in the car apparently failed. This has been verified by the dealer. Our safety was put at risk by being stopped in a dangerous location on a narrow 2-lane road at night with falling temperatures. The "Electrical Failure" warning happened simultaneously with the vehicle losing power.
