Toyota Supra Problems — All Years, Common Issues & Reliability

Manual transmission vehicle. The electric parking brake can automatically release when letting the clutch out with the vehicle in neutral if the brake and gas were recently touched. This YouTube video clearly describes the problem: [XXX] This can present a roll away hazard when leaving the vehicle parked with the engine running. With the vehicle in neutral, clutch in, foot on brake, engage the emergency brake, let off the foot brake, touch the throttle, then let off the clutch with the vehicle still in neutral and the emergency brake will release automatically and the vehicle will start rolling away with no feet on any pedals. It appears the vehicle is trying to auto release the parking brake as if you were going to drive away, but the vehicle knows it is in neutral not in 1 or R so this should not occur. The timeout for brake and then throttle though is very long. This dangerous behavior has caused my vehicle to roll away after I shut the engine off on multiple occasions. luckily I noticed before I had exited the vehicle and was able to re-engage the parking brake. There may be other circumstances that trigger this automatic release as well, I'm not sure, but I am always concerned that the brake may turn itself off and my car may roll away.

The contact owns a 2025 Toyota Supra. The contact stated while driving at an undisclosed speed, the infotainment screen intermittently darkened and remained inoperative. No warning lights were illuminated. The failure had occurred on several occasions. The vehicle was taken to a dealer where it was diagnosed and determined that the receiver and the infotainment system control module needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 300.

The issue appears to be related to the vehicles electronic parking brake for manual transmission vehicles only. When stopping the car and with the car in neutral and engine running, the parking brake is applied per standard operating procedures. However sometimes the parking brake will disengage itself, seemingly at random. This caused a rollaway issue for me twice thinking that the car was in "park" when it wasn't. This was also verified by a Toyota technician during a routine service appointment who documented the issue. There appears to be some chatter about this online with other owners complaining about the issue here: [XXX] Another person on YouTube also documented the issue here: [XXX] I believe this is a very serious issue as a rollaway vehicle can be extremely dangerous for pedestrians.

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.

My windshield glass cracked while I wasn’t even driving it. I was told it was due to a rock chip, but I could find no evidence of it. Toyota refused to cover under warranty, so I had it replaced at a total cost of over $900.
