2020 Toyota Supra Complaints

ENGINE — Filed 03/19/2026

I am reporting a safety concern involving BMW and Toyota vehicles equipped with the B58 Technical Update (B58TU) engine, commonly found in 2019–2021 models. These engines use a variable displacement oil pump with an internal thermoplastic adjusting component that regulates oil pressure. Field reports show this component can fracture, causing sudden loss or instability of oil pressure—most often during cold starts in low temperatures. When the part fails, oil pressure regulation becomes erratic or disappears entirely, often with little or no useful warning before engine damage or vehicle disablement. Reported early signs include failed electronic oil level readings, abnormal pressure behavior, or sudden drivetrain malfunction messages. Failures can quickly escalate to engine shutdown or severe mechanical damage from oil starvation. A loss of lubrication may disable the vehicle without warning while driving or shortly after startup, creating a safety hazard—especially in winter conditions when failures are most frequent and occupants may be exposed to freezing temperatures. Repairing the issue requires major disassembly, and oil pump replacement alone typically costs $6,000–$8,000 if the engine has not been harmed. Owners cannot reliably determine whether their cars contain the original plastic based pump or a later metal component revision because VIN based parts data now shows updated components even when no replacement occurred, and BMW has removed the original plastic pump part number from dealer systems. Failures have been reported across multiple production years, and the exact population of affected vehicles remains unclear. Because this defect can cause sudden, warning free vehicle disablement—particularly in cold weather—I believe it warrants investigation as a potential safety related issue. One of the main indicators of this issue is the inability to determine oil level, my car has never been able to determine oil level. Thank you.

The contact owns a 2020 Toyota Supra. The contact stated that while attempting to start the vehicle with the Push-to-Start button, the vehicle hesitated while starting. A message that the engine was overheating was displayed. The contact stated that the vehicle was idling in Low Power Mode while at a stoplight, and the vehicle hesitated while accelerating with the accelerator pedal depressed. The vehicle then suddenly jolted forward. The failure was temporarily fixed after shifting to SPORT Mode. The vehicle was towed to a local dealer, where the starter was replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was towed to a local independent BMW Service Center, and the starter was replaced; however, the failure reoccurred. The manufacturer was made aware of the failure. The failure mileage was approximately 25,000.

I am reporting a safety concern involving BMW and Toyota Supra vehicles equipped with the B58 Technical Update (B58TU) engine, commonly found in model years 2019–2021. These vehicles utilize a variable-displacement engine oil pump containing an internal thermoplastic adjusting component responsible for regulating oil pressure. Field failures are increasingly being reported in which this internal component fractures, resulting in sudden loss or instability of engine oil pressure. The failure frequently occurs during cold-start operation in low ambient temperatures. When the component fails, oil pressure regulation becomes erratic or is lost entirely. In many cases, drivers receive little or no actionable warning prior to engine damage or vehicle disablement. Reported precursor symptoms include inability to electronically measure engine oil level, abnormal oil pressure behavior, or sudden drivetrain malfunction warnings. Failures may rapidly progress to engine shutdown or mechanical damage caused by oil starvation. Loss of lubrication can cause the vehicle to become disabled without warning while driving or shortly after startup. This creates a safety hazard, particularly when vehicles become immobilized in active traffic or during winter conditions the cold is when they fail the most, where occupants may be exposed to freezing temperatures while awaiting assistance. Replacement of the oil pump requires extensive disassembly of the vehicle and repairs commonly exceed $6,000–$8,000 for just the pump, assuming the motor is unharmed. Owners are currently unable to determine whether their vehicles contain the original thermoplastic oil pump design or a later revised version utilizing metal internal components, as VIN-based parts information now identifies updated components in the car even when no replacement has occurred and the old components are actually in the car. Multiple BMW and Supra owners are experiencing this costly issue. Please investigate this issue.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER — Filed 01/01/2025

The 2020 - 2025 Toyota Supra is manufactured by BMW and uses virtually all components supplied by BMW. The vehicle includes dual climate controls (driver / passenger) and the temperature of the air from the vents is controlled independently. It is known by BMW that the blend door or the actuator (motor) - which regulates how much cold versus hot air is mixed per the control setting - can break or be deformed. This is a manufacturing defect in the heating unit, not a wear issue. No heat is available to the driver either through the center vent, the left vent, and most importantly from a safety standpoint, the vents at the windshield. This means defrosting or defogging the windshield during winter is virtually impossible because only extremely cold air is available on the driver's side. Since it is made by BMW, the Supra is at risk for the same issue. There are several reports on the internet from Supra owners and many, many from BMW owners who identified the problem and even attempted to create stronger replacement parts. On or about July 26, 2021, NHTSA published two safety recall / service bulletins for BMW and Mini for this problem: SI M64 02 21 and SIB 64 06 21. The cost of repair through Toyota or an independent repair shop is purportedly several thousand dollars because the entire interior dash must be removed to access the heating unit to replace the defective part(s). The Toyota Supra should be subject to the same safety recalls and the repairs should be provided by the dealership or authorized repair shop.

BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE — Filed 11/15/2024

The vehicle Parking / Backup / Cross Traffic assist warnings do not work unless the objects are within approx 2 feet of the car. When backing up there is no warning of any on coming traffic or a child behind the car. If a individual is at the rear of the car there is no visible or audible warnings. Only warning is either seeing the individual in the rear window or on the camera. This has been brought to the manufactures attention and they say this is the normal operation. All other cars I have had cross traffic and pedestrian alerts have visual and audible alerts. The car says that it is suppose to have them.

Rear hatch will not open electrically and/or from the interior manual release handle. If someone gets stuck in the trunk or a pet, won't be able to come out. I had items I bought and if they included battery or dangerous item, my safety would be at risk. There is no rear realse hatch button from the outside the car. NO other problems or accidents. Is there any additional weight mounted on the rear hatch (e.g. a spoiler)? No Does the latch release electrically? No 4. When attempting to release electrically, does the latch make a noise? No, but you can hear a light click in the wiring when you press the trunk electronic button 5. Does the latch release from the interior manual release? (NOTICE: Only attempt to release using light force. If excessive force is applied, additional damage may occur.) No 6. Does the interior manual release cable feel stiff when pulled gently, or does it extend and rebound freely? Manual release cable feels stiff when pulled genlty

There was a beep and then my dashboard went completely blank (was just dark) so I couldn't see any information such as how many miles per hour I was driving or how much gas I had or my navigational information or what gear I was in. Then the dashboard came back on and it said there was reduced driver assitance (but did not say what was wrong). The dealer says my dashboard should not have gone blank but they can't fix it since not sure why. This is very dangerous and should be addressed.

SERVICE BRAKES — Filed 11/04/2021

I scheduled an appointment to get an oil change and recall issue taken care of by a Toyota dealership near me. I dropped it off in the morning and when I called to check up on it in the afternoon they did not even begin to work on the car. I had picked it up because they said they were unable to get to it. Keep in mind they were still working on other cars that were simply pulling in. I had scheduled my appointment a week prior to get this issue taken care of. Now I am putting my safety at risk because they failed to take care of the issue.

VISIBILITY/WIPER — Filed 02/08/2021

WINDSHIELD CRACKS FROM VERY VERY TINY KNICK, ABOUT THE SIZE OF 1/2 OF A GRAIN OF SALT. I AM IN MULTIPLE TOYOTA SUPRA GROUPS IN FACEBOOK AND NUMEROUS PEOPLE HAVE COMPLAINED ABOUT THIS ISSUE. I FEEL THE WINDSHIELD DOESN'T MEET SAFETY REGULATIONS FOR IMPACTS. THE WINDSHIELDS APPEAR TO LOOK LIKE A SINGLE PANE OF GLASS, NOT LAMINATED DOUBLE PANE.
