On the 2020-2025 Toyota Supra B58, the BMW-sourced B58 inline-6 in the A90 Supra develops coolant loss without visible external leaks. The expansion tank cap and electric water pump are common culprits. In some cases, the charge air cooler (intercooler) develops internal micro-cracks allowing coolant into the intake.

This issue also affects: BMW 2 Series, BMW 5 Series, BMW Z4

Common Symptoms

  • Coolant level slowly dropping
  • Low coolant warning on dashboard
  • No visible external coolant leak
  • Sweet smell from engine bay
  • White residue around expansion tank cap

How to Fix

Replace expansion tank cap first (BMW 17137640514) - the most common and cheapest fix. Test electric water pump for leaks (BMW 11518632586). If coolant continues dropping, pressure test the charge air cooler for micro-cracks. Upgraded expansion tank caps with higher pressure rating are available from Burger Motorsports.

On the 2020-2025 Toyota Supra, the A90 Supra's BMW-sourced B58 engine develops coolant leaks from the electric water pump and its associated hoses. The plastic water pump housing can crack, and the O-ring seals deteriorate. The issue is more common after 30,000-50,000 miles and during temperature extremes. Since the cooling system is pressurized, even a small crack leads to rapid coolant loss and potential overheating.

This issue also affects: BMW 2 Series, BMW 5 Series, BMW Z4

Common Symptoms

  • Low coolant warning light
  • Coolant puddle under car
  • Sweet smell from engine bay
  • Coolant level dropping between services
  • Steam from engine area

How to Fix

Replace the electric water pump and O-ring seals. Use genuine BMW/Toyota parts — aftermarket plastic housings crack sooner. Some owners upgrade to an aluminum water pump housing from aftermarket suppliers like Billet Kings or Burger Motorsports. Check the coolant expansion tank for cracks as well. The repair is $500-$1,200 depending on parts used.

Owner tips & cautions

  • TipThe B58 water pump is a known weak point shared with the BMW 340i and M240i. An aluminum housing upgrade ($200) is cheap insurance. Do it before it cracks and leaves you stranded.

On the 2020-2025 Toyota Supra, the ZF 8HP51 automatic transmission exhibits rough or jerky shifts at low speeds, particularly 1st-to-2nd and 2nd-to-3rd gear changes during city driving. The mechatronic unit's valve body can develop wear causing harsh engagement. Cold weather worsens symptoms.

Common Symptoms

  • Harsh 1-2 and 2-3 shifts at low speeds
  • Jerking during parking lot maneuvers
  • Clunking when shifting from Park to Drive
  • Shifts improve significantly when transmission is warm

How to Fix

Have dealer perform TCU software update (latest calibration reduces shift harshness). Transmission fluid change with BMW/ZF LifeGuard 8 fluid (83222289720) at 50,000 miles improves shift quality. If mechatronic unit is worn, replacement runs $2,000-3,000. ZF 8HP is generally reliable with proper fluid maintenance.

On the 2020-2023 Toyota Supra, early A90 Supras developed rear differential whine under acceleration, most noticeable at 30-60 mph. The electronically controlled limited-slip differential (eLSD) can produce a whining or humming sound from improper gear mesh or bearing preload.

Common Symptoms

  • Whining noise from rear under acceleration
  • Humming that changes with speed
  • Noise louder during hard acceleration
  • Noise disappears when coasting

How to Fix

Have dealer inspect differential for proper gear pattern and bearing preload. Toyota issued a software update for the eLSD controller that reduces noise in some cases. Differential fluid change with 75W-85 GL-5 synthetic may help. If gear mesh is incorrect, differential rebuild or replacement under warranty.

Typical repair cost:$0 - $3,500
