SERVICE BRAKES, ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM, STEERING, VEHICLE SPEED CONTROL
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.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

FUEL/PROPULSION SYSTEM, ENGINE, POWER TRAIN
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.

SERVICE BRAKES
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.

UNKNOWN OR OTHER
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.

ELECTRICAL SYSTEM
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

ENGINE
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.

LANE DEPARTURE: WARNING, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

ENGINE, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

POWER TRAIN, ENGINE, STEERING
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.
