2020 PORSCHE TAYCAN Complaints

As per the recently announced investigation on 5/21/21 into the 12 volt battery issue that rendered the car unable to drive, I had the same issue arise today (5/22/21) where an electrical error made the car inoperable and unable to power on any systems. In order to get the car on flat bed tow truck, they had to charge back the 12 volt battery to get car into neutral.

Car displayed the following message: "Electrical System Error" and simultaneously lost all drive train power and mobility. Would not restart.

My car on two separate occasions lost power and took several seconds to recover while fighting it. It would suddenly state "Drive Attention Required" and seemed to hit the brakes hard and ignore my inputs. This occurred twice within a week roughly 3 weeks ago. This could have easily caused an accident as the car begins to slow quickly. The issue was not reproduced by the dealer and they claim it was related to a faulty software update (but they never reproduced or had any diagnostics on the issue so I'm not sure how they could claim that). It has not happened after the third reinstall of the software update but it also didn't happen except those two times when the software was apparently faulty so I still believe it could happen at any time. When the software was in a faulty state (which was common with the update and many had the same issues) the car's self driving tech was also semi functional and easy to have the car drive itself without knowing. The car would say "Driver's assistance inactive on the screen" but then drive itself at some unknown speed. I have a video of this. This is super dangerous.

After a software “upgrade” the speed control features were stated to be “unavailable” however the car still was in cruise and accelerator was depressed without indicating that to me as the driver. Car accelerated unintentionally on highway and emergency action had to be taken to avoid accident.

While driving in a particularly curved section of highway 1 the vehicle lost all power and control. I had to wrestle the vehicle to the side of the road and narrowly avoided a cliff face off into the ocean. My entire family was in the car and could have been killed. This was after Porsche was unable to fix safety systems like my active cruise control and lane keep assist which were bugging out and trying to take over control of the car. I towed it to Porsche who attempted to address the problem and claimed it was fixed with a patch. There is no way to validate the work. Porsche did not communicate during the issue and offered little in the way of resolution.

AS I WAS COASTING TO A STOP AT A STOPLIGHT THE CAR SHUDDERED AND LOST ALL POWER FROM THE ENGINE. I WAS ABLE TO STOP THE CAR AND A RED WARNING ON THE DASHBOARD SAID 'DRIVE SYSTEM CONTROL FAULT, PARK VEHICLE SAFELY'. I'VE HEARD FROM A NUMBER OF OTHER TAYCAN OWNERS AND THEY HAVE HAD THE SAME PROBLEM WHILE DRIVING, IN SOME CASES ON THE FREEWAY AND HAD TO STOP IN THE LEFT HAND LANE. I BELIEVE THIS FAULT IS VERY DANGEROUS AND SERIOUS. I AM VERY CONCERNED THIS COULD HAPPEN TO ME WHILE DRIVING AT SPEED, AND COULD RESULT IN AN ACCIDENT AND/OR INJURY TO ME OR OTHERS. THE CAR DID RESET AFTER I TURNED IT OFF AND RESTARTED, AND I DID NOT HAVE A PROBLEM FOR THE REST OF THE DAY. THE CAR IS CURRENTLY AT THE DEALER.

WHILE DRIVING ON THE FREEWAY AT C. 55MPH IN MODERATE TRAFFIC, THE CAR LOST ALL MOTOR POWER AND STARED TO COAST TO A STANDSTILL. AN ERROR WAS ON THE DISPLAY SAYING 'DRIVE SYSTEM CONTROL FAULT - PARK VEHICLE SAFELY. I MANAGED TO GET TO A SLIP ROAD OFF THE FREEWAY AND THE CAR JUDDERED TO A HALT FROM AROUND 15MPH UNTIL COMPLETE STOP. THERE WAS NO RESPONSE THE THROTTLE AT ANY TIME. I POWERED OFF THE CAR USING THE POWER BUTTON ON THE DASHBOARD, THEN IMMEDIATELY SWITCHED IT BACK ON. ONCE BACK ON, THE CAR WAS OPERATING NORMALLY. THIS HAS BEEN REPORTED ON PORSCHE TAYCAN FORUMS HTTPS://WWW.TAYCANFORUM.COM/FORUM/THREADS/MOTOR-CONTROL-ERROR-AND-SYSTEM-ERROR.3114/

THE CAR SHOWED AN ELECTRICAL ERROR & LOST POWER THEN SHUT DOWN ON THE FREEWAY. ONCE THE CAR CAME TO A COMPLETE STOP I WAS UNABLE TO GET OUT OF THE VEHICLE BECAUSE IT LOCKED ME INSIDE. THIS IS A SAFETY HAZARD AND HAD I NOT TAKE THE PRECAUTIONS TO EXIT THE FREEWAY I MAY NOT HAVE SURVIVED. THIS NEEDS TO BE INVESTIGATED AS FROM WHAT I'VE READY, THIS HAS BEEN A COMMON ISSUE IN THIS VEHICLE. IT HAPPENED FIRST ON THE ,'DECEMBER 16TH & THEN AGAIN DECEMBER 25TH. SOFTWARE AND THE 12V BATTERY WERE REPLACED THE FIRST TIME, AND THE DAY AFTER THE CAR WAS PICKED UP FROM SERVICE IT HAPPENED AGAIN.

ON TWO DIFFERENT OCCASIONS THE CAR HAD CATASTROPHIC FAILURES DUE TO THE 12 V BATTERY DRAINING FOR NO REASON. AND ONE OCCASION THE CAR HAD A CATASTROPHIC FAILURE DUE TO THE MAIN BATTERY SYSTEM HAVING A FAILURE. ALL OF THIS HAPPENED IN THE FIRST FOUR MONTHS OF OWNERSHIP. ALL TIMES THE VEHICLE WITH STATIONARY.

WHILE DRIVING, CAR BEGAN TO SHAKE ABRUPTLY AND STOPPED ITSELF. DASH FLASHED MOTOR CONTROL ERROR IN RED AND THE SYSTEM CONTROL ERROR AND WAS COMPLETE UNRESPONSIVE AND UNDRIVEABLE. CAR WAS TOWED TO PORSCHE AND THEY HAVE NO ANSWERS AFTER 3 DAYS. THIS WAS VERY DANGEROUS, AS THE CAR SLAMMED ON THE BREAKS AND STOPPED IN THE MIDDLE OF THE ROAD. HAD IT BEEN A HIGHWAY, I COULD HAVE BEEN HIT.
