Three NHTSA safety recalls are open and unremedied on my 2020 Porsche Taycan 4S: 25V896 (high-voltage battery — cell-module short circuit / fire risk), 24V732 (battery inspection, cell-module replacement, software update), and 24V455 (front brake hoses — cracking and brake-fluid leakage). Open status is confirmed by the manufacturer's own lookup at [XXX] as of XXX. The recalls cannot be completed because the manufacturer's authorized network refuses to confirm or schedule the work. The vehicle originated in the US and is now registered in [XXX]. In December 2025 the authorized dealer (Winner Porsche Center Kyiv Airport) refused, stating recalls are performed only for vehicles originally sold on the local market. I escalated to Porsche AG in XXX; the case was reviewed by Porsche Central and Eastern Europe and the official importer. After inspecting the vehicle in XXX, the dealer tried to condition recall work on my acceptance of unrelated paid repairs, and in XXX stated in writing that it reserves the right to refuse manufacturer campaigns due to "existing defects," without identifying any technical dependency between the cited findings and the recall work (brake-hose replacement and battery inspection/software are unaffected). A final written request with a 10-business-day deadline expired in XXX with no response from any Porsche entity. Safety risk: a battery fire risk and reduced front-brake performance remain unremedied on a vehicle in regular daily use. No warning lamps or symptoms; the risk arises from the unrepaired recall defects themselves. The refusal is confirmed in the dealer's written statements and documented in correspondence with Porsche AG, available on request. The vehicle is available for inspection upon request.

NHTSA complaint #11755828 — an unverified report by a vehicle owner.
I own a 2020 Porsche Taycan 4S (in service Nov 2, 2020) with a performance+ HV battery. I am currently facing a third round of module replacements. The service chronology and detail is set forth in the attached e-mail I sent to Porsche and the attached service reports. The safety concern I have is that when the defective modules fail, the vehicle suddenly becomes inoperable. The last failure incident in April 2026 resulted in the vehicle blocking in two other vehicles until it could be removed on a flatbed. I simply do not feel safe driving a vehicle that could shut down whenever the next module failure happens. There are 33 modules in the HV battery. 15 have been replaced already and it is clearly an ongoing issue as the vehicle is currently in service for a third round of module replacement after the vehicle shut down only 4 months and less than 2,000 driving miles after the previous module replacement. As a result of my increasing safety concerns, I requested Porsche replace the entire obviously defective HV battery. As set forth in the attached response, it refused to do so, stating that the "path forward remains continued diagnosis and repair in accordance with Porsche’s technical guidelines." My belief, and I know I am not the only one based on my review of Taycan message boards, is that Porsche is slow playing how it addresses what is a clear defect in many HV batteries to get to the end of the 8-year battery warranty by doing periodic piecemeal module replacements and then taking the position that post-warranty module issues are an "aging" problem for which Porsche is not responsible.

While driving my Porsche Taycan through a high-speed intersection, the vehicle suddenly displayed battery and chassis system error messages instructing me to pull over immediately. Before I could safely move the vehicle to the side of the road, it completely lost propulsion, speed control, and steering capability, causing the vehicle to abruptly slow to 0 mph in active traffic and leaving me stranded in the middle of the roadway. This created an immediate safety hazard, as approaching vehicles nearly collided with my car because it effectively performed an unexpected emergency stop without warning. Approximately one month earlier, the vehicle experienced the exact same failure while parked, displaying battery and chassis errors and losing power and steering functionality. The vehicle was towed to an authorized Porsche dealership, where it remained for approximately one month; however, the dealer was unable to diagnose the problem and returned the vehicle to me, stating that no fault could be found. Just two days after the vehicle was returned, the identical failure occurred again while I was driving. After restarting the vehicle multiple times at the roadside, I was eventually able to move it to a safer location, where it failed again shortly thereafter. The vehicle is currently at the Porsche dealership and is available for inspection. The dealership has indicated that the issue may be related to the high-voltage battery but has not yet identified the root cause or completed repairs. The only prior warning of this defect was the nearly identical battery and chassis system failure that occurred approximately one month before this incident.

NHTSA complaint #11727627 — an unverified report by a vehicle owner.
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

While charging my 2023 Porsche Taycan 4S at an Electrify America station, white smoke began emitting from the front wheel/charging port area. The vehicle also produced a burning odor inside the cabin. I immediately stopped charging and unplugged the vehicle. The smoke ceased within approximately 1–2 minutes. The vehicle was towed to an authorized Porsche dealership. Initial explanation from the dealer was steam from when radiators heats-up, which is inconsistent with the conditions and prior use history. Upon further inspection, the dealership identified battery-related issues. Ultimately, I was told that 8 out of 10 battery cells were replaced. The vehicle was out of service for approximately one month. The dealership stated that the battery cell issue was not related to the smoke event, which is concerning given the timing and severity of the incident. This vehicle had previously been subject to a battery-related recall addressed via software update only. I believe there is also ongoing litigation related to battery safety in this model. Given the smoke event, burning odor, and significant battery component replacement, I am concerned about the safety of this vehicle, particularly risk of thermal event or fire during charging. Note, I have a video of the smoke when car was charging, not able to upload video here

There are currently hundreds (if not thousands) of cars, operating on roads of USA, that at any particular time stop in the middle of the road. The power is cut off and Engine Control Error is displayed on the monitor. This issue has been described many times on Reddit, under Taycan-Engine Control Error threads. The affects 2020-21 Porsche Taycans. As an owner of '21 Taycan, I have run into this issue 8 times in the past 4 months. I have been lucky so far not to cause any incidents. I've brought in my car 3 times to Porsche dealership. The first time, a fix was made, but it did not do anything. The second time I brought it in, I was told that there is a transmission issue, but since the dealership can't replicate this issue, they can't fix it. After the second attempt, I contacted Porsche headquarters, looking for resolution. The customer service requested for me to bring the car back to dealership for additional analysis. After I brought the car to dealership, I waited for over a month and then received an email from Corporate Customer Service- there is nothing wrong with my car. So, I'm still driving a car, that can and will stop at any moment. I warned Porsche corporate that if the next time my car stops for no apparent reason and this leads to an injury or worse, someone at Porsche will be charged with manslaughter. Even though Porsche Corporate knows that these cars are a problem, the company refuses to address this issue and blatantly lies to clients, hoping that no one wants to take on a big corporation. How long will it be, until there is a serious injury or worse happens due to these sudden stops? I have all the communication between myself,orsche corporate and Porsche North Seattle showing the exact dates, when these issues happened, the attempt to fix them, the text message from dealership telling me that there is a transmission issue and lastly the email from Corporate, stating that there are no issues with this car. Please take a look. Thank you.

This incident is related to the ARB7/24V-732 recall, first communicated to me in November, 2024 and again in July, 2025. The July, 2025 letter states that software would be installed in the vehicle to test the health of my vehicle's battery, at a Porsche Center. I believe that this was actually performed over-the-air at my home. It's my guess that because the software was installed over-the-air, the normal process to close out a recall did not occur. I did not receive notification that my vehicle was determined to be healthy, and it isn't clear when NHTSA did. The slow or non-reporting of the vehicle recall status has had a ripple effect, as practically every third party tracker of recall information believes that the recall is still active on my vehicle. This is impacting the vehicle's worth in the market and may be impacting insurance rates and other vehicle health-dependent service costs. Porsche claims that it is my responsibility to correct the record of the vehicle with third parties, when it is their negligence that is causing the work. I see this as unfinished work on their side, and I ask NHTSA to help drive Porsche Cars North America to complete their work. Moreover, Porsche should be compelled to notify all customers whose health check was performed remotely that their vehicle was found to be healthy and that the recall was lifted on their vehicle. Lastly if it is not mandated that the OEM is responsible to communicate the resolution of recalls performed without service receipts, then this should be considered alongside any other updates to law. Thanks for any help that you can provide.
NHTSA complaint #11724719 — an unverified report by a vehicle owner.
The vehicle’s battery module became defective and would not accept or hold a charge. When attempting to charge the vehicle using standard charging equipment, the battery system repeatedly failed to initiate or complete the charging cycle. The vehicle displayed charging error messages and/or failed to respond when connected to a charging source. Despite using properly functioning charging equipment and verified power sources, the battery module would not charge. The issue was diagnosed as a defective battery module. As a result, the vehicle became inoperable due to the inability to recharge the high-voltage battery. This defect created a safety concern because the vehicle could unexpectedly lose available driving range and become disabled without warning. The failure rendered the vehicle unusable until the battery module required repair or replacement.
NHTSA complaint #11721039 — an unverified report by a vehicle owner.
I am reporting a safety defect involving (1) sudden loss of propulsion (“turtle mode”/limp mode) while accelerating/merging into traffic and (2) unintended steering movement while driver-assist/lane centering was active (vehicle jerked toward adjacent lane and off roadway). These events create an immediate crash risk. The vehicle has also had repeated charging-related overheating/charging stoppage events, which I believe may present a fire risk when charging in a residential garage. Repairs have been attempted multiple times by an authorized Porsche dealer, but defects persist. Warranty has now expired, and an independent scan shows ongoing network/data bus/12V monitoring faults consistent with continuing electrical/network instability. I am requesting NHTSA review for a potential safety defect investigation/recall.

The in-cabin heater stopped working, and the temperature is in the single digits outside (currently 7 degrees), so I was not able to use the defroster to clear my windshield and it was dangerously cold inside the vehicle.
NHTSA complaint #11715768 — an unverified report by a vehicle owner.
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 complaint #11703735 — an unverified report by a vehicle owner.
The car suffered a critical electrical failure which resulted in the car abruptly losing power when driving at a speed of about 30 mph. The speed at which the car became unresponsive was so rapid that the car could not even be maneuvered from the middle lane into the right most lane for safety. The cars digital display system indicated nothing except that the hazards were on (after I had attempted to turn them on) and a red box with two cog wheels inside of it. In reality, the hazard lights were NOT on externally as was evidenced by a number of vehicles stopping to tell me to turn on my hazards. Additionally the car would not respond to any commands whatsoever. The car would not go in to park or drive and could not be powered on/off. The brake pedal was able to be pushed to the floor. The doors which have an electronic assist system were difficult to open because the whole electrical system was in a failure state. The car had to be towed to a Porsche dealership. Upon arrival to the dealership, the car indicated an engine control error on the digital dash and showed a turtle icon. This was not the case during the original failure (prior to tow) and only showed that state after a multi-hour tow trip. There were absolutely no indications of this problem prior to it happening. The car was at around 40% state-of-charge. Porsche performed a software update on the car and drove it 120 miles but could not recreate it. The very same day I took the car back from Porsche, the same issue occurred but in a less critical way and in a parking lot. This time, the car suffered an engine control error but after walking away from the car for 10 minutes or so, the error was gone and the car was drive-able. In both cases, one thing i noticed was that the rear spoiler was stuck in an extended state after the failure had occurred.

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.

This is a brand new electrical vehicle (2025), with just under 1000 miles on it. I was driving on a medium-speed highway when an electrical system error message appeared suddenly and the car lost the ability to accelerate. I coasted into the shoulder, shut it off, and unsuccessfully tried restarting it a few times before it came back on without the error message and allowed me to drive a few more miles. About 5 minutes later, the same thing happened--the same message appeared and it suddenly stopped accelerating. I coasted for a short distance but was only able to get partially out of the road. The car had to be towed. Porsche identified problem with one of the battery cells, and estimated 3 weeks for repair.

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 complaint #11692022 — an unverified report by a vehicle owner.
On 9/18/2025, while driving at approximately 45 mph on a busy road called Hualapai in Las Vegas, Nevada, my Porsche Taycan suddenly displayed “Electrical system error – Park vehicle in a safe place”. The car immediately slammed to a stop in live traffic. I heard a loud thump from the front end as this occurred. I was nearly hit by six cars swerving to avoid me in the rain. Gladly no one made contact and no one was hurt. My car turned into a brick in the middle lane with lots of traffic sort of like I brake checked them all. I lost all steering as it locked up, I couldn't get out of fast moving traffic as the car wouldn't go back into drive and had to toggle to neutral and push the car. This was a life-threatening failure that created a dangerous hazard for me and other drivers.
