2021 Toyota Supra Electrical System Problems

The contact owns a 2021 Toyota Supra. The contact received notification of NHTSA Campaign Number: 25V636000 (ELECTRICAL SYSTEM); however, the part to do the recall repair was unavailable. The local dealer was contacted, and it was confirmed that the part was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

See attached document for complaint. Toyota Motor North America, Inc. has failed or is unable to remedy the safety recall (NHTSA Recall No. 25V-636), issued on 26 September 2025, for my 2021 Toyota Supra within a reasonable period of time. According to the non-dated letter from Toyota, the recall is for a defect in the engine starter relay that may catch fire without warning “during vehicle operation or when the vehicle is parked and the ignition is off” (Toyota Recall No. 25TA09). The letter further states that “owners are advised to park their vehicles outside and away from structures until the recall remedy is complete” and that “the remedy can be available in the last quarter of 2025.” This defect is serious. For safety I am afraid to drive the vehicle, because it could catch fire without warning. The vehicle is parked outside in the winter weather, instead of in my garage. The promised date for a remedy has passed (last quarter of 2025) with no further information from Toyota. I contacted Toyota via telephone on 3 December 2025 and again on 13 January 2026, without resolution. I sent letters to Toyota Vice Presidents on 15 January 2026 (copy attached), but I have had no response to date. Currently Toyota has not indicated when the necessary repairs will be available, if ever. Please use all of your authority to bring this matter to a satisfactory resolution. Further delays are not a satisfactory resolution, because Toyota has my money for a car that I cannot drive and that depreciates each month. Toyota has major financial incentives to delay.

The contact owns a 2021 Toyota Supra. The contact received notification of NHTSA Campaign Number: 25V636000 (Electrical System); however, the part to do the recall repair was not yet available. The dealer was contacted. The contact disconnected the battery after parking the vehicle outside to prevent the vehicle from catching on fire. Additionally, the contact expressed that he was making monthly payments for a vehicle that was undrivable due to a fire risk. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and informed the contact that another notification would be mailed when parts became available. The contact had not experienced a failure.

Odometer Fraud. The contact purchased a 2021 Toyota Supra. The contact stated that after obtaining the vehicle's Carfax history report, it was discovered that there was a mileage discrepancy. The vehicle was a private dealer sale. At the time of purchase, the vehicle mileage was 47,764, and after receiving Carfax history report, it was discovered that the mileage was 72,650.

Vehicle fails to restart after automatic ignition shut off when pressure is removed from brake pedal causing vehicle to shift into neutral without engine power. Vehicle also fails to start showing "starter system fault" error.

Passenger side low beam headlight suddenly stopped working on the highway. Symptoms same as Toyota recall 19TA20, however vehicle is not part of the recall campaign. Vehicle displayed error "Right low beam malfunction". Dealership is not willing to investigate under recall coverage.

I own a new 2021 Toyota Supra and along with other owners of this new model, there is a safety issue that has been identified. There is a repeating issue with unresponsive/unpredictable throttle behavior for me and other Toyota Supra owners. It only happens on a cold start, when going in reverse on a slope (exiting the garage) and when traction control gets engaged (the wheel gets in the air for a second due to the curb/slope). After this maneuver either the engine gets stalled or the throttle starts to behave unpredictably. Specifically about the latter — pressing on the pedal does nothing for 2-3 seconds but then suddenly the engine revs go high and the car jumps ahead, even if the pedal is not pressed anymore. As if it's a 2-3 seconds lag between the pedal press and the wheel spin. This happened to me at least 20 times during the time of ownership (6 months). My trip to the dealership didn't help as I could not replicate the issue (only happens on cold start). I've contacted the manufacturer (Toyota USA) but they were unable to help and only documented the case. I have tens if not hundreds of Supra owners in an online community reporting the same issue. We are also aware that this issue is affecting owners globally, but Toyota has not yet made any statements about it. This issue is a safety concern and I almost got into an accident because of it. It requires attention before anyone gets hurt. Will be happy to assist and provide reports from other owners in the US. I've also attached the error codes that appeared at the time of the last accident and an invoice from the dealership. Thank you.
