2022 PORSCHE TAYCAN Complaints

Sudden loss of power while on freeway with several errors being thrown onto driver's screen. Unable to accelerate. Was forced to coast to shoulder of road and come to a complete stop. Turned off vehicle and turned on again and issue was resolved.

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.

Electrical System Failure and Engine Failure. Car just stopped in the middle of the road at the traffic light and would not move forward. This has happened for the second time since the purchase of the car in December 2022. The car is now at the dealer being checked.

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.
