Total electrical shutdown of the drivability of the car. The car in driving traffic came to a sudden stop and doors were lock and would not start until we tried 3 times. A truck behind us had to come to a quick sudden stop to avoid hitting us in the rear of the car! The car was taken to Porsche South bay for understanding the cause of the problem the manufacture was alerted ,Porsche customer care and a case filed. Porsche Service was suppose to report their findings to Customer Care in reference to case file number. They asked me to also bring in the Porsche charging unit to be re-flashed on software in the unit. I have had the car in multiple times for PCM related issues and software updates, during the most recent update they had to replace the entire PCM with a new one. The car was running fine then, then this issue happened. …
Conditions were clear and dry, with an ambient temperature of approximately 86 degrees F. Time of day was approximately 11:41am, Pacific. I was entering the 73 South onramp from Newport Coast Dr. (Newport Beach, CA 92657), somewhere between 60-70mph in Sport Plus mode, under heavy acceleration (but not full throttle). With no other symptoms or indications, the vehicle suddenly lost motive power and presented the error message "Electrical System Error Park Vehicle in Safe Place." At that point, the throttle became completely unresponsive and the AC compressor shut off, though other vehicle systems appeared to work normally. I was able to pull over to the shoulder safely, however sudden and complete loss of motive power is very clearly a safety risk when on a highway. …
While driving my electric vehicle, I experienced a sudden loss of power. The car abruptly stopped, leaving tire marks on the street, and the steering wheel began shaking. At the same time, an error message appeared on the dashboard, indicating an engine failure and instructing me to pull over immediately for safety. Fortunately, I was driving alone that day and had chosen an alternative residential route, which allowed for slower speeds and less traffic. Had this incident occurred during my usual commute, where I typically travel at least 45 mph on a heavily trafficked three-lane road, the outcome could have been catastrophic. I am certain that the sudden loss of power in such conditions would have led to a serious accident, endangering not only myself but also other road users. The service center required a full week to duplicate the issue. …
I was charging at a Tesla Supercharge using the OEM Porsche converter and my car experienced a catastrophic electrical fault. The charge completed but the charger was hard to pull out and then my car had battery fault errors and said it needed immediate service. I took it to the dealer and they pulled these error codes and said severage battery componets had failed including a failed high-voltage battery controller, which is mounted on top of the HV battery and the high-voltage booster (which distributes DC voltage). Porsche is not claiming responsibility and presented me a $17k bill to replace. I'm concerned the temp sensors went off and that this could have led to a fire so I wanted to flag to your office. …
My 2020 Taycan Turbo was purchased brand new by myself July 07/ 2020, and has had a tremendous amount of problems and issues. All are documented and have photos as proof. The car is available for whomever wishes to inspect it. One of the more recent issues was the car - without warning - while I was driving, not functioning and I wasn't able to turn the wheel, use the gas pedal, the brake or anything. Nothing in the car was operable. After it coasted ( I was almost rear ended but luckily the other driver veered off the road to avoid a collision.) the brakes decided to work. A red light came on which reads " Engine Control Error, Park vehicle in a safe place " , along with photos of 2 cars with exclamation points on them. Also illuminated was a photo which shows a photos of a drive train and 4 wheels. After turning the car on and off several times, the car decided it would operate. …
As I was driving on the freeway at approximately 50 mph, the car lost power and would not accelerate. A warning appeared on the dashboard reading: " Engine control error - park vehicle in a safe place". There was no roadway shoulder, but fortunately I was coasting downhill and was able to exit the freeway onto an exit ramp, where I parked the car on the shoulder. I called Porsche roadside assistance and waited over 45 minutes for a tow truck. It had still not arrived when I was able to restart the vehicle and resume driving. I took it to the dealer where I bought the car, and they said they would check it out. They did not indicate that any other Taycans had been returned to them with this issue, although I have read numerous news accounts describing this problem in recent weeks. …
I was driving 30 mph in drive mode on westheimer rd when the car suddenly emergency braked and lost all power i went from 30 to 0 in about a second. Yes the car is available for inspection on request. The car had 180 miles of battery power. The car behind me slammed their brakes on and nearly slammed into the rear of the car. The red warning light came on "Electrical System Error park vehicle in a safe place". There was absolutely no warning before this occurred. I am afraid for my life with this car i nearly got into an accident at 30 mph let alone if i was on the highway i could have easily died. This problem has been reported with thousands of porsche taycans. The car has been at the porsche dealership for a week so far where they are reporting electrical faults in the car.
