2023 Toyota Supra

Parking brake is releasing on its own. I would press the clutch in when starting the car and as soon as i release or press down again it will release. Car is also in neutral when I am doing this so it has nothing to with it being in gear and releasing. The parking brake should on release when I pull the button or if i am in gear and want to pull off.

Electronic parking brake will intermittently release unintentionally. Replication scenario is to set the parking brake, depress clutch pedal, put transmission in neutral, then release the clutch pedal. This can happen right after starting the car, or after the car has been in operation. Note that this is the manual transmission version of the car. Other owners have reported similar problems.

When I start the car and put the transmission in neutral, the parking brake releases on its own. Depending where I am parked, the car will slowly roll. I usually just re engage the parking brake especially if i don't plan to drive at that very moment. What component or system failed or malfunctioned, and is it available for inspection upon request? Parking brake How was your safety or the safety of others put at risk? The vehicle can roll back or forward and can put others at risk. Has the problem been reproduced or confirmed by a dealer or independent service center? No Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No

This vehicle (in particular the new manual transmission equipped one) has a system which automatically disengages the electronic parking brake when you try to drive away with it applied, and that system does not have enough interlocks or "rules" that govern when it activates. In certain circumstances, the car will automatically disengage the parking brake with as little user input as simply letting the clutch pedal out - even if you've just come to a stop and applied the parking brake immediately before letting the clutch pedal out. Given that the only safe way to exit the vehicle with the engine running is with the parking brake applied and the car in neutral, this over-active system easily results in a rollaway vehicle hazard. This happened to me twice and I didn't understand at the time what was going on, but I have mostly isolated the conditions under which it has happened. The system seems to be looking for recent brake and throttle inputs, and if those inputs have been triggered recently then letting the clutch pedal out will automatically disengage the parking brake. However, "recently" seems to be very liberal, as you can touch the brake and throttle and then wait at least ten seconds (and potentially longer) then let out on the clutch, and the system will automatically disengage the parking brake. Additionally, the system does not seem to care if the car is in neutral or in gear. The car is aware of what gear it's in at all times, as this information is displayed in the instrument cluster with R, 1, 2, 3, 4, 5, or 6 indicating which gear you've selected, or N for neutral. Obviously if you're in neutral, you're not attempting to drive away, so the system should never activate when the car is in neutral. I have additionally documented this issue in a video here: https://youtu.be/GXAR1Q-ApUQ

Going west bound on I30 in Arkansas traveling with the flow of traffic. There was a transition part of the highway where it went from some asphalt repair to concrete roadway and when my car hit this the wheel seperated in a 360 degree pattern and the only thing holding the wheel together was the tire. I believe the 19" wheel that Toyota used on this 2023 Supra has a factory defect and is very dangerous and needs to be looked into ASAP. There was no damage to the car at all.

Some 2020 – 2026 model year Supra vehicles may exhibit OBD-related DTC codes that can't be cleared during emission testing

Some 2005 – 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.

Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: •Minor damage: requires only buffing to repair. •Moderate damage: usually requires neutralizing, color sanding, and buffing. •Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.

To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.

The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.

Toyota vehicles are currently protected with RapgardTM protective film designed to protect the horizontal painted surfaces. This material protects from acid rain, environmental fallout, and rail contamination. Follow the Removal Procedure in this bulletin to remove the RapgardTM protective film within 90 days from initial application.
