May 24, 2021Driver assistance
- Parking Assist has failed several times with message "ParkAssist not available. Continued driving possible, Service necessary" - Forward collision warning (aka Warning And Break Assist) has disabled itself several times for no apparent reason with message "WBA Limited, See owners manual". The sensors and windshield was clean so nothing was obstructing the system. - Headline Control error while driving with message "Headline control error. Temporary condition, Continued driving possible". ParkAssist and Forward collision unavailability has been reported to Porsche dealer but they were unable to diagnose or fix it. It seems the car does not record any error codes for the dealer to debug. There was a pending software updated at the time which was installed but the issues happen even after the updated. The issues started from first days of ownership and happen intermittently and stopping and restarting the car always fixes them which probably suggest they are software bugs. After the software update I have experienced an additional issue - Central computer (aka PCM) which controls everything in this car has frozen and restarted which leaves the driver with no ability to control any of the car's settings or systems.

At approximately 3:40 PM on 5/24/2021 I was travelling W bound on the 10 freeway. The vehicle experienced full power loss. Fortunately I was in the L most lane and could pull to the side. Had I been in the center lanes I would've had serious safety issues. Vehicle is being towed to Beverly Hiss Posrche. I took a photo of the error message and can share it if needed. This was a particularly traumatic experience as the vehicle has been in the repair shop for 35+ days since purchase in November with electrical issues. It was returned on 5/17/2021 after a second control module was replaced.

While driving at approximately 40mph, a red message suddenly appeared in the dashboard saying “Engine Control Error- Park vehicle in a Safe Place”. Simultaneously, the car became unresponsive - for example, pressing the gas pedal had no effect. I was able to brake and drift to the side of the road, but the car kind of bumpily ground to halt, feeling almost as if I had a flat tire (which I did not). Once I shut off the car and restarted, it ran again but had that issue occurred at a high speed or on a busier roadway, a serious accident was possible. I just recently had the car serviced to do a major upgrade the software and have seen others posting in forums about this serious issue. I never had this issue prior to the software update and have driven the car over 5000 miles.

May 22, 2021Speed control
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.

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.

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.

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.

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.

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.
