2020 Porsche Taycan Complaint Log

I am reporting a safety issue with my Porsche Taycan. On two separate occasions within the past month, the vehicle has experienced a sudden and complete loss of power while I was accelerating hard on the highway. In both instances, the vehicle immediately entered “turtle mode,” severely limiting performance to the point where there was effectively no power available to maintain speed or safely maneuver with traffic. The only way to restore normal operation was to fully stop the vehicle, turn it off, and restart it. This creates a dangerous situation, especially at highway speeds, as it exposes me and other drivers to a high risk of collision due to the sudden and unexpected loss of propulsion.

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. Here are the fault codes provided from Porsche: B192BF0 - High-voltage DC charger (booster) in wrong mode P33E500 - Quick battery charging (DC), Charge stn., initialization error U15AB00 - Quick battery charging (DC), Communication error between vehicle and charging station U15AE00 - Quick battery charging (DC), Charging station communication failure U15B300 - Fast battery charge (DC) – cable testing error P33F000 - High-voltage system activation, Malfunction B1A88F0 - Actuator for right charge port door – travel error U15AC00 - Signal damping log, Malfunction B200000 - Control unit – function restriction U140900 - Internal temperature measurement, Implausible signal

Made a turn into a street and driving at slow pace (about 20mph) and the vehicle suddenly shuddered and came to complete stop and died in the middle of the road. I had no time to pull over. No warning. It just happened. Fortunately, no oncoming or cars behind me. There was a red dash board warning “Engine Control Error”. I turned off the vehicle and restarted.

The EV had a “Engine Control Error” and suffered engine failure on Jan 6th 2026 at 5:17pm. It happened out of nowhere without any warning at low speed.

This vehicle can not be driven on straight roads of freeways without the "take over steering warning" engaging. This is problematic, this morning on icy roads driving on straight roads the warning engaged, braked and cut power and put the vehicle into a slid on icy roads. This warning also happen frequently on freeway driving, suddenly braking and almost causing drivers behind the vehicle to react to the sudden braking putting this vehicle in jeopardy of rear end collisions or other possible accidents.

There are .recalls.on the Vehicle I had been unaware of and I dropped off my vehicle for exterior buffing while person Buffing vehicle he heard a loud explosion and when he looked the vehicle was up in flames the vehicle burned. There was a Risk of someone getting Harm , Killed and Damages to other vehicles on the property in same lot vehicle was being buffed . Police and Fireman were dispatch to location.

Just took the car back from the dealer after a major recalls and EV motor Failure

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.

During my ownership, the vehicle experienced multiple dangerous failures. It suddenly lost power while driving with my 2‑year‑old child onboard, and on another occasion the steering wheel locked for several seconds on the freeway. The car has had numerous recalls, and the dealer later confirmed an EV motor failure but offered no buyback. These defects created serious safety risks and caused significant financial loss, which I believe requires NHTSA’s attention.

While driving the vehicle, an error message (Engine Control Error) will pop up. The car will come to an immediate stop…forcing the driver to shut off car and restart it. This has happened multiple times and in one instance occurred on the highway. It almost caused a catastrophic accident as the car came to an abrupt stop in the middle lane of the highway. I’ve taken the car to the dealership multiple times and they have not been able to fix it. I’ve read many Taycan message board posts and it seems like this is a common issue amongst multiple years of Taycans. This is a serious safety issue and a recall should be issued with a remedy for this. Due to this, I cannot drive the car on the highway as I’m scared of it happening randomly. This is a known issue and one that should be recalled and handled appropriately by Porsche.

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 vehicle experiences a sudden and dangerous malfunction while driving. Without any prior warning, the vehicle begins to shake and then immediately brakes on its own, coming to an abrupt stop in the middle of traffic. Only after the vehicle has already braked and shut down does an “Engine Control Error” message appear on the display. There is no advance alert and no time for the driver to react or move out of traffic. This is exceptionally concerning especially as this vehicle was being used a primary mode of transportation for my 2 young toddlers who were present in the vehicle during these failures. The vehicle was purchased directly from Porsche as a Certified Pre-Owned vehicle in June 2025, and was represented by Porsche as having passed all safety and mechanical inspections at the time of purchase. Despite this, the vehicle has continued to experience catastrophic failures. Following the initial shutdown incident, the vehicle was towed to Porsche for service on September 2. Porsche stated that the issue had been repaired and assured that the vehicle was safe to operate. However, on September 29, the same failure occurred again. The vehicle shook, abruptly braked in active traffic, shut itself down, and only then displayed the engine control failure message. This shows that the underlying defect was not corrected and continues to pose a serious safety hazard. The problem is severe, unpredictable, and reproducible. It places the driver, passengers, and surrounding motorists at immediate risk because the vehicle becomes immobilized in traffic with no prior warning and no ability to pull over safely. The vehicle has been inspected by Porsche technicians, but the root cause remains unknown, and Porsche has been unable to provide a successful repair or assurance of safety. This pattern strongly indicates a critical defect in the engine control or power-management system that renders the vehicle unsafe for public road use.

I brought my vehicle in to a Porsche dealer on May 24th 2025 for a noise coming from the front right wheel area. There were some other issues but those were not safety related. They stated the vehicle has an open recall campaign for a brake hose. That there is a risk it could break. It is now July 18th 2025 and the dealer has had the car the entire time since May 24th 2025. They are saying they can't complete the safety recall due to no parts. Porsche has issued a STOP order for dealers selling affected vehicles. Porsche has issued a STOP order for dealers to use affected vehicles as loaners. It seems I should STOP driving the car as well yet the dealer indicated it is to give it back to me unrepaired.

I am writing to bring to your urgent attention a recurring and serious issue with my Porsche Taycan (VIN: [XXX] ). On multiple occasions while driving, the vehicle has suddenly lost all power and displayed the error message: "Engine control error. Stop the car in a safe place." When this occurs, the car becomes completely unresponsive and unable to move forward, posing a significant safety risk, especially when it happens in traffic. I am forced to stop, switch off the vehicle, wait for a couple of minutes, and restart it. The error message disappears after restarting, but the issue continues to recur. This has now happened three times in the past two months. I first brought the vehicle to the dealer after the initial incident, and they recommended a software update. However, after the issue reoccurred and I returned to the dealership, they were unable to retrieve any error codes. Despite these efforts, the problem persists. Given the severity of the issue and the risk it poses while driving, I am requesting immediate assistance and a thorough investigation into the root cause of this malfunction. This is not only a mechanical concern but a serious safety issue that requires urgent attention. Please let me know the next steps to have this addressed properly and whether a formal case can be opened for further diagnostics and resolution. Thank you for your prompt attention to this matter.

While driving, shortly after a turn, the electric motor has a fatal error resulting in complete loss of power while driving. The car has to be stopped in the middle of the road and powered down and then turned back on. This clears the fault but the problem has occurred 3 times within a month resulting in me not driving it anymore.

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. While there were no prior warnings, messages, or symptoms leading up to this event on my car after researching the incident it is clear that this same instance occurred in over 10,000 like kind vehicles under NHTSA recall number 21V-486. This unexpected failure poses a significant safety risk, and I am deeply concerned about the potential for recurrence, especially in less forgiving traffic conditions.

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 making a left turn after being stopped at a traffic light - just a few moments after the turn, all of a sudden I experienced violent jerking motions of the car, and lost all power in the middle of traffic, and rolled to a complete stop. This was an exceptionally dangerous place to just have the car stop responding. I noted an error message "Engine Control Error" with a red ring around it in the rightmost instrument cluster. I turned on my hazard lights; other electrical functions were still working in the car (e.g. music was still playing over the audio system). I power cycled car off and then on again, and cleared the error, and the car drove normally again. The problem did not recur despite driving about 5 miles more on the way home. I have stopped and started car and drove brief periods several times since then without issue. The state of charge was about 75%, having charged last night at home on AC to 80%. Ambient temperature outside was hot today, almost 90 degrees F, and very humid.

Vehicle lost all power with no response from the accelerator pedal causing me to almost get killed on a two lane highway. I was able to somehow coast into the grass on the side of the highway

Vehicle randomly thinks that I’m about to be in a collision when nothing is in front of me. This causes the vehicle to just stop and almost causes me to have an accident.

It was stop and go traffic. I was distracted and the car failed to auto stop and I hit the car in front of me. The alert did come on after the collision. I would assume the automatic braking failed or the collision would not have occurred. It was a low speed impact so not a major safety risk but even a minor collision can have a significant injury in susceptible subjects? The problem has not been reproduced to my knowledge. The component has not been inspected. The car has been evaluated by a body shop for damages and the damages are significant. The warning light came on in an inadequate time to prevent the collision. There were no other warning lamps

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.

On three separate occasions over the past year, my car's emergency collision avoidance system was triggered, (an alarm sounded, a red symbol was on my dash, and the brakes locked), erroneously. No accident occurred, but in the second case below, it caused the car behind me to lock up their brakes and just avoid hitting me...thankfully they were very alert. The first two occasions happened two months apart, but at the same time of day and at the same location. On both occasions, I had driven down a street at approximately 7:30 in the morning. I slowed to make a left turn and then came to a complete stop because traffic was coming in the opposite direction. There was also a car facing me in the alternate lane of the road that I was turning into. Once all oncoming traffic had passed, I pressed the accelerator to make a left turn and turned and moved forward just a few feet when the emergency collision avoidance system was triggered and the car's brakes locked. Within a few moments, the system released and I was able to drive on. Both situations were identical in location and the traffic situation was as I just noted in both cases. The most recent occasion that the system was triggered happened this week. I was in a right turn lane with a car in front of me and one or several cars behind me. I had come to a stop behind the car in front of me who was waiting to make a right turn onto the road. Our turn signal was red. Once the turn signal turned green, the car in front of me moved forward and made the right turn. I accelerated and went about 25 feet and was about to join the road when the collision avoidance system activated, (an alarm sounded, a red symbol was on my dash, and the brakes locked). The car behind me skidded to a stop, luckily without hitting me, and then my car's system released and allowed me to drive on. This must be happening to other users. If so, Porsche should be made aware and they should fix this.

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.

There is obviously a design flaw in the fan cooling system for the main high voltage 93.4 kw battery. The cooling vents allow small gravel to enter the intake ports powered by fans to cool the battery. (this is a major issue for areas of the country where gravel is used for winter road maintenance. This issues arises every snow season) Gravel gets into the ports and can possibly jamb the fan propeller blades thus not being able to cool the battery properly. I have a work order at the dealership to clean out the cooling ducts. when the gravel enters these ducts they make a grinding sound when the fans engage. The dealership reported this to the manufacturer, and the response from the manufacturer was it is not their issue. The service dealership said additional screening over the intake ports can not be done because information from the manufacturer states this would impede the necessary airflow to cool the batteries. To further bring attention to this design issue, the high voltage 93.4 kw battery failed, July 19, 2023 at 17,551 miles.

The rear view camera on all Taycan models and years are unsafe and unusable as they are so wide angled that you can not reliably use them as it is almost impossible to see anything.

My car fail to start or move after a charge, have to get it tow to dealer, My rear strut making a popping noise dying the summer n winter the noise limited There a puddle of water on my passenger rear left side floor

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.

On March 30, 2023 I had my winter tires and wheels changed out for my summer tires and wheels Goodyear Eagle F1 Asymmetric 3 in sizes 265/35ZR21 101Y XLand 305/30ZR21 104Y XL. At the time, I had about 25,000 miles on the car, and perhaps 15,000 miles on the summer tires. The tire inspection report from Porsche indicated that I had acceptable tread depth on all tires, and no unusual treadwear. Around the end of June I started seeing a very slow pressure decrease in my left rear tire, from about 41psi to 38 psi over a few weeks. On July 18, I experienced a severe drop in pressure to 22 psi and I filled the tire with air to 45psi and used the tire sealant to drive the car to the Porsche dealer, and arrived with 29psi. At no point during the time I had the summer tires on did I ever do anything unusual, or hit any road hazards. Porsche provided me the attached video showing severe cracking between the sidewall and tread around the entire diameter of the drivers side rear, and cracking around part of the diameter of the passenger rear. They claimed this was due to 'misalignment' of the rear tires. The alignment report (attached) shows the drivers rear was within specification, and the passenger rear was 0.2 degrees out of camber (-1.8 deg vs spec of -1.6 deg). There was still 4mm of tread on the tire, and no unusual tread wear was noted on any tires. I have replaced all 4 tires, and am very concerned that the same thing may happen, and I could have a catastrophic failure at high speed. Porsche is unwilling to do anything other than pay for the drivers tire. I don't see how I can be assured that the exact same thing won't happen in the future, since there was no testing or observation that Porsche did that indicated any kind of problem.

The contact owns a 2020 Porsche Taycan. The contact stated that while driving at an undisclosed speed, the vehicle lost electrical power and stalled. The contact stated that he was able to veer to the side of the road. The contact was able to restart the vehicle; however, the failure recurred while driving. The contact stated that while making a right turn, the instrument cluster became inoperable. The contact was able to reboot the vehicle and the instrument cluster became operable. An unknown message was displayed. The service warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the battery had failed and needed to be replaced. The vehicle remained at the dealer for additional diagnostic testing. The vehicle was not repaired. The manufacturer was notified of the failure and offered to partially cover the repair. The manufacturer referred the contact to the dealer. The failure mileage was approximately 10,482.

The car was suddenly stalled at road multiple times, showing red warning "Engine control error. Park vehicle in a safe place" . Porsche is unable to solve such major safety issue of its electric car for past two years.

Main HV Battery failure, "Electrical System Error" displayed, fortunately this occurred when pulling into the garage. Vehicle would not go into drive or reverse, vehicle had to be towed to the dealership. This could have ended very differently if on the highway. HV Battery Module and 12v battery replaced.

The contact owns a 2020 Porsche Taycan. The contact stated while driving 35 MPH, the power steering failure, and multiple warning lights were illuminated. The contact stated that the vehicle started to decelerate independently and failed to accelerate while depressing the accelerator pedal. The contact was able to park in a nearby driveway. The contact was able to restart the vehicle within 10 minutes and drove to her residence. The contact took the vehicle to the local dealer, where it was diagnosed with needing the gateway control unit to be replaced. The vehicle was repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 15,000.

I was driving in the fast/lane of the freeway, and suddenly the car flashed red "Electrical System Error" "Park Vehicle in Safe Place". The car immediately started to decellerate on its own and I didn't have time to go over to the right so had to move into the left shoulder of the freeway. I was stuck in the middle of the freeway, with cars driving fast coming around a bend of the freeway behind me having to swerve out of the way. Cops finally came to give me cover from behind. Dealership still trying to figure out what the issue is.

Car displayed the following message: Electrical system error Park vehicle in a safe place

My Taycan suddenly lost power while driving on the road on 10/14/2022

Porsche Mobile Charger overheats, rated for 9.6kw but due to safety concerns Porsche adjusted default rate to 4.8kw. Rate can be reset to 9.6 each charge session increasing risk of fire.

Porsche Taycan has been plagued with recurrent electrical issues despite 2 factory recall messages and reported fixes. The car screen and gauges all blacked out while driving despite reportedly fixing this electrical problem. Further a serious brake issue occurred (pedal going all the way down making harsh sound) within 2 years. If that’s not enough the car had an “serious electrical system” error message with yellow battery “requires service” and been in the shop for 4months and they apparently cannot fix it. These are all major safety issues for a brand new car within the first 2 years of purchase.

In the center of the lane on a straight highway, vehicle will suddenly brake without warning. There are no vehicles ahead. A warning light comes on the dash and says “Driver Control Required,” yet both my hands are on the steering wheel. The feeling is that of a brake check performed by the electronic sensors of the car, and not at the driver’s command. Had there been a car following behind me, he could have hit me in the rear. Dealer is aware of the complaint but says, “system is working as designed.” Manufacturer responds by directing me back to the dealership. Yet the problem persists.

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.

After the most recent recalls were repaired (all software) on my vehicle the brakes in the car were terrible. Soft /dead pedal feel. I almost rear ended other cars multiple times wen braking at slow speeds. Occasionally the pedal would go all the way to the floor when slowing to 3-5mph - This was consistent over multiple days after I got the car back from recall updates. Also , the first inc of brake pedal travel did not slow teh car at all.

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.

HV battery failure. No warning. Vehicle could not be put in gear or moved. Vehicle has been at Porsche Conshohocken since 12/23/2021. No resolution as of 02/04/2022. Vehicle has been out of service 47 days.

The backup camera is highly distorted and it is difficult to see what is in the distance (more than 10 ft) from the rear of the car. I have had multiple incidents where I almost hit someone who was walking up the street past my driveway entrance. The other problem is when you turn the backup camera turns, and there is no frame of reference left so it is extremely distorted and hard to figure out where things are at. I have a Mercedes GLS450 and the backup cameras clearly show the street at the end of our driveway. I've attached comparison views of the street from our garage using the Porsche and Mercedes cameras. This backup camera is hazardous to the safety of anyone walking across the backup path of this car, and this issue needs to be addressed immediately. There is just no excuse to have such a poor quality camera on any car. By the way this car cost $50,000 more than my Mercedes!!

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.

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.

The backup camera is highly distorted and it is difficult to see what is in the distance (more than 30 ft) from the rear of the car. I have had two incidents where I almost hit someone who was walking up the street past my driveway entrance. I need to look in the opposite direction for oncoming cars and I rely on the backup camera to see if anyone is walking towards the driveway entrance as I'm backing up. The resolution on the camera is absolutely terrible and highly distorted. We have a Ford F150 pickup and a Mercedes 350 GLE and the backup cameras clearly show the street at the end of our driveway. I've attached comparison views of the street from our garage using the Porsche and Mercedes cameras. This backup camera is hazardous to the safety of anyone walking across the backup path of this car, and this issue needs to be addressed immediately. There is just no excuse to have such a poor quality camera on any car.
