Toyota GR Supra B58

The Toyota GR Supra B58 has a reliability score of 74/100, rated "GOOD". BMW heart, Toyota badge, solid performer

The most frequently reported issues are Coolant Expansion Tank Cracking, Electric Water Pump Failure, First-Year (2019-2020) Build Quality Issues, Oil Filter and Oil Quality Sensitivity, among others. See the Known Issues section above for symptoms, affected mileage, and repair costs.

Yes, this is a documented issue on the B58, typically appearing around 40,000-100,000 km. The plastic coolant expansion tank on the B58 is prone to hairline cracking at the seams over time, especially with heat cycling from spirited driving. This causes slow coolant loss and can trigger a low coolant warning before any visible puddle appears. It is a known wear item across the wider B58 platform, not specific to the Supra tune. Typical repair cost: €150-500. DIY difficulty: Easy to Moderate.

Yes, this is a documented issue on the B58, typically appearing around 60,000-120,000 km. The B58 uses an electric water pump with a plastic impeller that can crack or delaminate from its shaft over time. Failure causes a loss of coolant circulation and can lead to overheating if not caught early. This is a recognized wear item across BMW B58 applications and is not unique to the Supra. Typical repair cost: €400-900. DIY difficulty: Moderate.

Yes, this is a documented issue on the B58, typically appearing around 0-50,000 km. Community consensus strongly indicates the 2019-2020 model year Supra A90 had a range of first-year production problems that Toyota addressed in the 2021 model year update, alongside the ECU power recalibration. Buyers of early cars may encounter issues that were corrected mid-cycle. Typical repair cost: €200-1,500. DIY difficulty: Easy.

Yes, this is a documented issue on the B58, typically appearing around 0-200,000 km. Community sources specifically flag the importance of using correct OEM-quality oil filters (Mann or genuine BMW/Toyota filter recommended) on the B58. Using substandard filters can affect oil pressure and long-term engine health on this high-output application. Typical repair cost: €50-200. DIY difficulty: Easy.

Yes, this is a documented issue on the B58, typically appearing around 80,000-200,000 km. As a high-output turbocharged straight-six producing between 250 kW and 285 kW depending on model year, the B58 in the GR Supra demands strict adherence to oil change intervals and quality. Community sources note that neglected oil changes and poor-quality lubricants accelerate wear on turbo bearings and valvetrain components. Typical repair cost: €300-1,200. DIY difficulty: Easy.

The A90 GR Supra with the B58 is a genuinely capable sports car with a strong engine underneath, but buyers should target 2021 or newer examples to avoid first-year build quality issues and get the recalibrated ECU tune. Maintenance history is everything here, the B58 rewards careful owners and punishes neglect, particularly around oil change intervals and filter quality. Parts costs and servicing prices will be closer to BMW than traditional Toyota ownership, so budget accordingly. Confirm the fuel pump recall has been completed on early cars, and avoid any example with a modified or remapped ECU unless you can verify the tune and inspect for associated wear.

Do not choose between the two power outputs expecting a mechanical difference, the 2019-2020 and 2021+ B58 in the Supra are the same hardware with a different ECU map. The real reason to prefer a 2021 or later car is the bundled build quality fixes and standard higher-output tune, not the engine itself being different. If buying a 2019-2020 car, confirm the fuel pump recall was completed and budget for the same coolant system wear items as any other B58.

Before buying, check: Prioritise 2021 model year or newer, confirmed to have resolved known first-year production issues and running the recalibrated ECU tune; Check for coolant expansion tank cracking and inspect the electric water pump area for staining or residue; Verify the low-pressure fuel pump recall has been completed against the VIN, particularly on 2019-2020 cars; Request full service history and verify oil filter brand used, reject cars serviced with non-OEM spec filters; Check oil condition and level at purchase, dark, sludgy, or low oil is a red flag for neglected intervals on this turbo engine.

There's no fixed mileage limit, it depends on maintenance. The parts worth budgeting for proactively are: Coolant expansion tank (60,000 km), Electric water pump (80,000-100,000 km), Turbocharger (100,000 km), Oil filter (OEM spec) (10,000 km). Engines that clear these checkpoints with documented maintenance commonly continue well beyond typical ownership periods.

The in-tank low-pressure fuel pump supplied by Denso can develop a cracked impeller over time, which can swell and cause the pump to stall or fail to start the engine. This affected a wide range of Toyota, Lexus, and Subaru vehicles built in the 2018-2020 window, including early 2019-2020 GR Supra units. Remedy: Fuel pump replacement at authorised Toyota dealer, free of charge under the recall campaign, check VIN against Toyota's recall database for completion status

Estimated ownership cost is €4,500-9,000 over 3 years depending on mileage, service history, and whether any coolant system or turbo remediation is required, based on known issues and typical service needs.

Owners report real-world fuel consumption of around 9 L/100km.

Community-reported real-world usage suggests changing oil every 10,000 km using BMW LL-01 approved 0W-30 or 5W-30 fully synthetic (e.g., Castrol Edge, Mobil 1), often more conservative than the official service schedule.

The B58 is also found in: BMW 340i (F30/G20), BMW 440i (F32/G22), BMW 540i (G30), BMW 740i (G11), BMW X3 xDrive30i / M40i, BMW X5 xDrive40i, BMW Z4 M40i (G29), BMW M240i, BMW M340i.

Cautiously positive, the community acknowledges the B58 is a strong engine and the 2021 refresh resolved early problems, but there is ongoing debate about whether BMW-derived complexity fits Toyota's reliability reputation. Well-maintained examples are well-regarded, neglected cars raise concerns quickly, especially around cooling system components.
