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

Heater randomly stopped working, defrost won't function and that will cause a safety concern

NHTSA ODI 11499810

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.

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.

When driving the vehicle, the center console screen (the Porsche Communication Manager), spontaneously went blank/black. The screen appeared to reboot while the car was on and froze with the word "PORSCHE" across the center screen. The screen inoperable while the car was in motion. The navigation, climate control, back-up camera, radio, and many other controls are all utilize through this center touch screen. Those were all inoperable until the car was stopped, turned-off, and then turned on again.

While charging was in progress using Porsche's app at a charging station of Electrify America, the charging process suddenly stopped, when I switched from the app to an email app. And since the charging station displayed "Please unplug", I was unplugging a charging cable from a Taycan's charging port, then there was an explosion at the port with an ear-splitting bang and a large spark. The car dashboard then displayed "Electrical system error" and was totally unmovable, so it was towed to a dealer on 6/18/2022. The dealer contacted the manufacturer, but the car is still not repaired even though 40+ days have passed, which is unreasonable. I found the below article and suspect whether it's related with the "inexpensive onboard charger": - An excerpt from: https://www.teslarati.com/porsche-whistleblower-taycan-battery-charger-fires-coverup/ "Porsche uses an inexpensive onboard charger that does not control the process well, the whistleblower explained to me in detail. Fires have occurred in the Taycan battery, the source explained, due to the problem described."

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.
