Chronological view of owner reports
The contact owns a 2020 Porsche Taycan. The contact received notification of NHTSA Campaign Number: 24V732000 (Electrical System) after owning the vehicle for a week. The vehicle was taken to the dealer, who then stated that because the vehicle had an aftermarket charger inside, the repair could not be performed unless a charger was purchased from the dealer. The dealer confirmed that the aftermarket charger would not perform as needed, and the recall repair would not be successful. The vehicle was not repaired. The manufacturer was not informed of the issue. The contact had not experienced a failure.
Taycan HV battery cells/modules going bad causing the car to be a brick and not drivable and dangerous. Porsche is replacing the failed cells but it can be an ongoing issues that can spread to other cells.
The car once I started, it gave us a red warning that said electrical system problem. At that point, I was unable to put the car in drive or put the car in reverse. The only thing I was able to do is put the car in neutral. The car would not move. The same issue happened when I was driving with the car. It gave me the error message at which point I had to pull over on the shoulder.
I was notified of APB6 recall and received a mailing suggesting I don't use the charger and that I should buy an aftermarket charger and would be reimbursed. It has been over 3 months and I have contacted Porsche multiple times and they have created trouble tickets that have just expired. I have yet to be reimbursed.

I discharged the battery to 7% then recharged to 100% using my home charger. When I got into the car, I had an error message stating: 'electrical system error park vehicle in a safe place'. The message disappeared later that day and I was able to drive the car to the dealer.

Car displayed the following message: Electrical system error Park vehicle in a safe place
It appears that the vehicle 12volt system battery has failed and I am unable to move the vehicle . I have tried to charge the 12volt battery but the car remains undrivable. I had the car towed to the dealership and they have said that the car needs a new 12Volt battery but it is on backorder and that they continue to work with the factory to resolve the issue.
I got an “Electrical System Error. Park vehicle in a safe place” while I was on the freeway. I had to exit the freeway and shut down the vehicle and the error went away. I am hesitant to drive the vehicle, I am in the process of having the vehicle flat bedded to my dealer.
Suddenly my vehicle showed "electrical system error", then it can't move, no matter forward or reverse, luckily it was parked in my garage, I can't image if it was on highway when your vehicle suddenly lost power. I don't remember how many times my Taycan was recalled in past 1 year, but it looks Porsche still haven't figure it out, maybe it's still a prototype.
My Taycan 4S has now on two occasions, while I’m driving, on the freeway, during the daytime, had all the instrument cluster displays go blank for 20-30 sec then reboot… Very disconcerting at best... dealer tells me this is NORMAL!, hard to believe its normal.... for me it's a safety issue.
car failed on the street noting "electrical system error". it was not able to shift into drive or reverse and immovable rendering it inoperable and left me stranded on the street. I had the car towed to the dealer the next day.
sudden electrical failure. Two times the car has had sudden unexpected power loss. In particular the forward motion of the stopped suddenly, fortunately i was at low speed <20 mph. Both times electrical error message was noted on the driver's center screen. I was able to turn the car off and then attempted several times to turn it back on, eventually the car started. In my opinion there are no precipitating factors. Also fortunately there were no other cars behind me, otherwise i am sure an accident would have 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. In this case, as in the first time this happened, I shut the vehicle off and attempted to restart several times immediately following the initial error message, but the vehicle would not restart. I let the vehicle sit for approximately 10-15 minutes with the power off. At that point, the vehicle was able to be restarted and driven. This is the 3rd time I’ve received such an error and the 3rd time I’ve had the vehicle brought in for service for the same issue since August 2nd. Porsche Cars North America is apparently aware of the issue and has updated my vehicle software and replaced a voltage converter approximately one month ago. Unfortunately, the vehicle seems to still be exhibiting the problem.
Sudden and unexpected complete loss of power while vehicle was at highway speed. Could not accelerate. Red warning light appeared stating Engine Control Error. Car glided to a complete stop and I attempted to pull over to the shoulder of the highway. Brought the vehicle to the dealer and they stated there was a recent service bulletin to update software.
Engine light came on while driving "Engine Control Error" Park Vehicle in a safe place. As I was attempting to pull into a safe place the car died on the road resulting in a near accident
1st error “parking brake bit available, vehicle coils roll away” - cleared after restart. It then occurred again after cad was parked together with “motor control error - driving possible, service required” but car could not be driven and had to be towed
My car suddenly popped up this error message "Engine Control Error". I could still steer and use the brakes, but the accelerator would not work. I had to coast to a stop, put in park, and restart. I called the dealer and they said this will be part of a recall but they had no fix yet. I'm not sure if this part of the battery power-loss recall or not.
Sudden power loss while driving. Pulled over to the side and the car shut down with the message "Engine Control Error"
April 27 I tried a launch control and a few seconds into it I got "All wheel drive error. " Engine performance limited." The car slowed and would only drive a maximum of 20mph. It cycled through several screens, one said "Visit workshop". I tried to attached movie and photo, no luck. I let car sit turned off for about 10 minutes, drove it again, no errors. Tried launch control again, no errors. I have a .mov that shows the errors (My son was in the passenger seat so I had him record the errors). I cannot attach an .mov here. I took it into dealer, they said Porsche didn't have a fix for this but they said not to worry about it. It is dangerous to have the car only go 20mph at some random time!
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. Porsche is continually having issues with this car all related to the PCM, it appear that the car is unsafe and my wife refuses to be in the car. I asked Porsche if they were aware of this problem and they said yes. I asked Porsche for them to look at this car as a Lemon law car, they call this a Buy Back Program. I am still waiting to be told what is next. Porsche is saying the car is safe and has had no accidents, but they know that this car could cause an accident when shutting down with no notice. How is that considered safe? No message appeared till after the car shutdown.
While driving the car suddenly lost power and displayed "electrical malfunction" please park in safe place. I was powerless and stranded in the middle of a 3 lane road. Car was towed to Porsche and they have had the car for 2 days- with no solution in site.
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. Had this power failure occurred under different circumstances, I and other drivers would have been at risk of serious injury or death.
I had just entered Interstate 15 about a mile from my home. I was in middle lane going approximately 65 mph, error message "engine computer failure, please pull over to safe place and call for service" appeared on screen and car lost all motive power. I was able to pull over to side of road, shut car off and then restart car. I was then able to drive home. Had car towed to dealer next day. They said they needed to update two software modules to latest version which "should" fix the problem.
