Likely spend is the mid cost of every issue rated common or universal, added together, what an unmaintained example owes over the next few years, not a prediction for any one car. Worst case if everything here failed at once is €600, which isn't a realistic scenario but is a useful ceiling.

A slightly rough idle, a cold misfire, and a gradual loss of response over a long period. Direct injection means no fuel washes the back of the intake valves, so oil vapour deposits build up. The additional port injectors keep this far milder than on the German direct-injection engines, and it takes high mileage to matter.

Check: Borescope the intake valves, or simply ask whether the car has ever been decarbonised at high mileage.

How to read this

Every issue is authored once against the part that actually carries it: the engine, the gearbox, the chassis or a shared component, and inherited by every variant that has that part. The badge next to each issue says where it comes from, so you can tell an 4GR-FSE problem from an E9x problem.

Evidence tiers. Manufacturer means a recall, technical bulletin or revised part number. Documented means workshop data or multiple independent sources. Reported means owner consensus with no hard confirmation, and never sets a risk level on its own.
