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

In September 2023 this Porsche Taycan 4S accelerated suddenly while going very slowly in reverse after displaying a red warning message on the dashboard "Electrical System Error." The brakes did not work and the car crashed into a house. No one was injured, but the car was declared a total loss. I see a recent safety recall (April 19) on your website for issues with the lithium battery and I believe that this may have caused my accident. I did report this as a safety issue to you in 2023 and confirmed tracking number assigned by NHTSA for this issue is 11556555.

On two separate occasions under similar conditions, the vehicle initiated emergency braking due to a false collision warning. Both cases occurred at the same location. I was in the center lane facing into the afternoon sun waiting to turn left into a parking lot at a full stop. I was attempting to cross three lanes of traffic. When an opening occurred, I proceeded forward and began turning the wheel left as the traffic passed. I was not aggressive and waited an appropriate amount of time to begin the turn, well clear of the oncoming vehicles, which were traveling past at about 50 mph. The vehicle indicated a collision warning and slammed on the brakes. My daughter complained that her neck hurt from the sudden stop. I was fine, but it was jarring. The vehicle behind was able to stop in time as well, since I wasn't yet going fast, but both times was honked at (which I think demonstrates the degree to which it was an unexpected level of the braking). In both cases, the car returned to normal operation after the incident.

What component or system failed or malfunctioned, and is it available for inspection upon request? Electrical malfunction errors came on, brakes, and engine control warning lights came on. The speedometer dashboard went dark. The car started shaking. The car started to slow down on its own. How was your safety or the safety of others put at risk? I was traveling at 76mph on a six lane highway. The brakes were not responsive for a period of time, I had no way to see the car speed, the windows went down on their own in the back seats. It was 33 degrees outside, no heat in the car, the wireless phone charger stopped working. Has the problem been reproduced or confirmed by a dealer or independent service center? The car is being inspected by the dealership. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It is being inspected today. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, the brake warning light came on, an electrical malfunction light, and an engine control light appeared

The 240V charger cable has a recall due to overheating and causing fires. I am now having to charge my car with a slower cable. In addition, I have also heard that the battery can have issues with water and leakage causing fires as well. I am concerned with fires by charging the car in my home, and the fact that this car was sold to me, and the charger cable has been known to have issues for years, only now getting a recall letter in Feb 2024.

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)

The heater and defrost are not working which is especially dangerous during cold weather and/or humid conditions. The vehicle is at the dealership service center where they stated there have been a number of similar issues. The dealer has indicated they will inspect and repair. There were no warning lamps/messages prior to failure. To be fair, I never tried the heater before a cold spell this last week.

The cabin heater failed, so the windows mist up in the winter. Known problem for years, but it's not an active preemptive recall.

I received a red error stating that there was an electrical system error and I couldn’t operate my vehicle on Oct 18 when the vehicle was parked at home. I had to tow the vehicle to the dealer and when they inspected it, they couldn’t find anything wrong with it. I brought the vehicle back home and then less than a month later on November 7 I got the same error when the vehicle was parked at home. I had to tow the vehicle again to the dealer. And at this time they told me that there is an issue with the high voltage battery. They have not given me a loaner, and I am without a vehicle. I do not know when the issue will be resolved.

I was backing my Porsche out of my garage with my foot on the brake. The car backed slowly as expected for a few seconds, then flashed a red display on the dashboard (see attachment) warning of an electric system error. It immediately self-accelerated in reverse at a high rate of speed across the street. The brakes did not work. Within 4-5 seconds it hit my neighbor's house and crashed into a room. I was trapped in the car and had to have the fire department get me out. The video police downloaded from the camera over my garage confirmed my account to them (as written above). I can provide the video if you would like to have it. A DMV examiner told me that about a year prior, around June 2022 an exactly similar accident was referred to him involving a Porsche Taycan accelerating out of control in reverse (see attachment).

The contact owns a 2022 Porsche Taycan. The contact stated that when he purchased the vehicle, the vehicle would be fully charged in ten hours. The contact stated that after an unknown software upgrade was performed, the vehicle failed to fully charge. The vehicle was taken to the dealer, but no assistance was provided. The dealer referred the contact to the manufacturer for assistance. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 10,000.

Electric passenger compartment heater (high-voltage heater) Does not work. This prevents the cabin from receiving heat. This is extremely unsafe in cold environments because it prevents the windshield visibility as frost forms.

After 9 days the car showing 12V battery low, it completely was completely dead on March 01, 2023 despite my all efforts to drive around (more than 400 miles) and charging. Reported the issue to Porsche helpline and they arranged the vehicle pickup from my home same day and the car was serviced at Paul Miller Porsche dealership in Parsippany, NJ. They charged the 12V battery, updated the software and returned after 3 days. The big battery had around 35% charge when it happened. Luckily it happened at home but I’m nervous about taking it out and get stranded somewhere.

The heating system in my 2022 Porsche Taycan stopped working. In addition to it not being able to heat the cabin, I can't defog/defrost the windshield making the car unsafe to drive. I'm told by the Porsche dealer that this is a known issue, and the fix involves ordering a part from Germany with unknown ETA.

I have 71 documented cases of Porsche Taycan heating systems failing at https://github.com/evstatus/PorscheTaycan/issues/1 The issue affects all Taycan models going as far back as 2020. This is a safety issue that requires that the car be flatbed towed when the heating system fails, as it affects the ability to effectively defrost and defog the windows in cold environments.

No windshield defrosting and defogging in my 2022 Taycan 4S (purchased new a year ago). Impaired visibility. No heat in passenger compartment. Dealer found electric heater failed and needed replacement. The high-voltage electric in-line heater heats the coolant used for windshield defrosting and defogging, as well as passenger compartment heat. See attachment for system description. The Taycan electric heater is a critical vehicle component to ensure visibility and avoid crashes. In the last 2 years, over 70 Taycan owners (US, Canada, Europe) have reported Taycan electric heater failures in online forums. Three owners have had a second Taycan heater failure a year after the first heater was replaced. Taycan model years 2020, 2021 and 2022. See attachment for owner online posts with URLs.

The display is one LED unified panel and it goes dark and loses its ability to function while the car is in motion. It will prompt you to reboot while the car is in motion. In order to reboot the system driver must lean forward toward the passenger seat left portion of the screen and take 1 hand off the wheel to reboot and takes ones eyes away from the view plane of the road for more than 5 seconds

The vehicle has stalled out repeatedly while driving. When starting from an intersection it will lose all power and a turtle icon shows up on the screen and the car will not move more than 5 MPH. After rolling to a stop, and restarting the car drives okay. Then a few days or a week, month later, it happens again. Also, the PCM repeatedly weekly, fails to boot up and I have no backup camera or controls of the car. The dealer erases codes and gives the car back, they don't know what's wrong.
