Porsche Taycan 2020: Retiros, Quejas y Ley de Limón de California

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

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.

NHTSA #11695449

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.

NHTSA #11692022

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.

NHTSA #11709797

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.

NHTSA #11712514

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.

NHTSA #11720540

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.

NHTSA #11601648

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

NHTSA #11592619

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.

NHTSA #11582465

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.

NHTSA #11607758

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

NHTSA #11489430

My complaint is that the car will not move. I get in the car to drive and the car displays the following message, “ Electrical System Error. Stop vehicle in a safe place.” This has happened on numerous occasions(at least 7) since I received the car on February 10, 2021. Mind you I work from home so I don’t drive it but once a week. I am quite fortunate that thus far it has only happened in my garage. I took the car to the local Porsche dealership for a software update but that was not the solution. It occurred again after the update. I thought maybe it had something to do with the car charger because it usually occurred a couple days after charging the car but I haven’t charged it in over 2 weeks.

NHTSA #11419735

Complete battery failure. Luckily occurred in a safe location and while parked.

NHTSA #11421593

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.

NHTSA #11383427

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.

NHTSA #11377898

The tungsten carbide coating on the PSCB (Porsche Surface Coated Brake) rotors has failed at 44,000 miles. This is not normal wear. The Taycan’s regenerative braking system handles the substantial majority of deceleration under normal driving conditions, meaning the mechanical brakes on this vehicle have seen a fraction of the use they would on a comparable internal combustion vehicle at the same mileage. Coating failure under these conditions is consistent with a material or manufacturing defect. Porsche has issued Technical Service Bulletins addressing PSCB disc replacement on the 2020 Taycan, indicating this is a known issue. Porsche Cars North America was contacted twice requesting goodwill consideration and denied both requests, citing warranty expiration without addressing the vehicle’s braking profile or the existence of related TSBs. The cost of OEM PSCB rotor replacement is approximately $7,500–$10,000 including labor. No safety-equivalent aftermarket replacement exists for this proprietary system, leaving owners with no practical alternative to the full OEM repair cost.

NHTSA #11735150

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.

NHTSA #11465879

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.

NHTSA #11728424

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

NHTSA #11700183

The vehicle has now gone into Turtle Mode three times in the last month. Twice to dealership without fixing issue. Turtle mode renders the car undriveable. There is no propulsion, car won’t go over 20 mph

NHTSA #11734713

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.

NHTSA #11529278

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.

NHTSA #11703735

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.

NHTSA #11546706

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.

NHTSA #11674481

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.

NHTSA #11549218

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.

The safety risk of having the car’s motor completely lose power on the road/highway is high, as you are then left powerless. We have not reproduced this issue ourselves. Our local Porsche dealer has looked at it and said it was a “one off” type of malfunction and could not find any issue with the car when we brought it in. The car shut off while driving and gave a “Motor control error.” The car’s interior electronics stayed on, but the car had no drive power at all. There were no warning signs or problems prior to this issue occurring

NHTSA #11418476

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 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/

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.

NHTSA #11564207

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.

While driving normally on a highway, the car suddenly reported "Electrical System Error, Stop vehicle in a safe place", which is followed by a complete loss of power, even pressed on acceleration pedal. I immediately pulled over to the side of the highway, the car slowed down quickly and stopped. The car was unable to restart ever since. After 1-2 hours, the vehicle's power was completely lost.

NHTSA #11418935

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.

NHTSA #11415110

My 2020 Porsche Taycan 4S (VIN [XXX]) has a recurring, dangerous brake failure that remains unresolved after multiple dealer repair attempts. At low speed, the automatic emergency braking system activates on its own and begins decelerating the car. As the car slows to roughly 5 mph, the brake pedal drops, braking pressure disappears, and the vehicle keeps rolling forward. Pressing the pedal as hard as I physically can does not bring the car to a stop. On more than 5 occasions I have had to steer around the vehicle in front of me to avoid a collision. The failure is intermittent and unpredictable, which makes it especially hazardous. The problem has existed since early in my ownership. On [XXX] (16,631 miles), Porsche Livermore found multiple brake booster faults and replaced the brake booster assembly, re-bled the brakes, and recoded the PSM control unit (RO [XXX]). The dead-pedal emergency-stop failure continued. I returned on [XXX] (40,904 miles) for the same problem; the dealer recoded the PSM unit and reset the brake pedal value but classified the pedal travel as "normal" (RO [XXX]). I returned again in May 2026 (46,585 miles) reporting that the dead-pedal emergency-stop failure still remained. The dealer could not duplicate it and called it "operating as designed" (RO/Invoice [XXX]). No crash or injury has occurred only because I was able to take evasive action each time. The defect is unresolved and creates a serious risk of a crash, and I am reporting it so it is on the federal safety record.

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.

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.

Component/system: High-voltage (HV) battery system and power electronics. 2020 Porsche Taycan Turbo, VIN [XXX] . Vehicle available for inspection. Safety risk: Since January 2025, the vehicle has repeatedly displayed a "pull over and park safely" emergency warning and shut off unexpectedly while driving at highway and surface road speeds. Sudden loss of propulsion at speed created serious collision risk. Dealer-confirmed: Porsche Woodland Hills documented (July 2025): "vehicle just shut off on him as he was driving — multiple occurrences." A second shutdown was confirmed August 2025: "vehicle shut off while driving — high voltage battery error." Four or more repair visits under my ownership for this same defect. Fault codes confirmed by authorized Porsche dealers: P0AA600 (HV Battery Voltage System Isolation Fault — highest severity), P0A4000 (Rotor Position Sensor Fault), U178800 (Front Axle Power Electronics Drive Fault), P061B00 (Torque Calculation Fault). November 2025: Porsche Downtown LA isolated all 33 battery modules, found modules 6, 19, and 32 defective — all physically replaced. Vehicle out of service 9+ weeks. Shutdown warning recurred during same visit. Porsche NA (Case #XXX) denied repurchase. Warning lamps: "Pull over and park safely" warning and HV battery error appeared suddenly before each shutdown. No gradual symptoms. Recurring since January 2025. Additional: Prior owner records show HV battery water intrusion (February 2024) requiring full battery removal and reinstallation. In July 2024, dealer cleared "numerous inactive fault codes" without disclosure prior to my purchase. Porsche NA has acknowledged the issue by offering goodwill compensation while refusing repurchase. Cumulative out-of-service days for this defect exceed 75 days across multiple repair visits. I request NHTSA investigate whether this defect exists across other Taycan vehicles and whether a recall is warranted.

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.

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

NHTSA #11560785

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.

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.

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.

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!!

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.

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. I drove it to the dealership. More comments and issues to be added. - Numerous - Have photos of All

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.

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.
