The contact owned a 2020 Porsche Taycan. The contact stated that while the vehicle was stopped with the engine running, the contact exited a parking garage ticket booth and the vehicle independently accelerated. The vehicle crashed through the ticket booth gate and into a wall before coming to a stop. The contact inspected the vehicle and confirmed that the BRAKE HOLD assist was enabled. The vehicle was towed to a local tow yard. The vehicle was deemed a total loss by the insurance company. The contact was transported to the local medical center for treatment. The contact sustained bruises and cuts to the left and right hand, bruising to the back of the neck and a concussion. A Police report was filed; however, the information was unavailable. The failure mileage was approximately 19,400.

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.

Incident: April 23, 2026 · Filed: June 27, 2026

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. 

Incident: May 12, 2026 · Filed: June 25, 2026

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.

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.

Incident: January 15, 2025 · Filed: May 17, 2026

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.

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.
