Credov's researched list of the 3 faults the Toyota GR Yaris RZ is known for, 3 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Look for track or gymkhana stickers, tow-hook marks, heat-discoloured brakes, worn tyre shoulders, bucket seats, harness bolts, aftermarket.
Why it matters: Hard-used cars need gearbox, transfer and clutch rebuilds (see the gearbox and drivetrain notes). One Japanese owner with an aftermarket ECU and cat had idle hunting with the air conditioning on. Left unrepaired this grows into a major repair bill.
What to look for: Cold and warm, shift slowly and briskly in and out of 2nd many times, including 3-2 downshifts, and hold 2nd under load.
Why it matters: UK dealers adjust the gear linkage, which helps some cars but not all; in Australia and Europe numerous gearboxes were replaced under warranty. Long-term owners name it the main thing to check when buying. Left unrepaired this grows into a major repair bill.
What to look for: A judder pulling away, a high bite point, a burning smell or a rattle from the bellhousing at idle that changes.
Why it matters: Launching in Sport mode gives a burning clutch smell. Another owner's clutch slipped because oil leaking between the engine and gearbox soaked the disc. Left unrepaired this grows into a major repair bill.
