Known problems on the Toyota Supra SZ

Tuned Supras: flash tunes, downpipes and pops

Costly if missed

2019–2026 · petrol · Gearbox

What to look for: Look for aftermarket intakes, a non-standard exhaust, carbon-fouled tailpipes, crackling on lift-off and a check-engine light.

Why it matters: Tuned cars have often been launched hard and tracked, which loads the gearbox, diff and driveshafts. Left unrepaired this grows into a major repair bill.

Crankcase vent (PCV) valve in the valve

Costly if missed

2019–2026 · B58, B58B30M1, B58B30O1 · petrol · Engine

What to look for: Listen at the top of the engine for a whistle or howl that changes when the oil filler cap is loosened.

Why it matters: The diaphragm splits, crankcase pressure rises and oil is pushed past gaskets. Some later covers allow just the diaphragm to be replaced; others need a complete valve cover. Left unrepaired this grows into a major repair bill.
