Han descubierto un problema en los motores que montan nuestros yaris y yaris cross. Copio y pego la información de la noticia (está en inglés, pero en resumen: sufren de EGR)

Upd. The bad news for European car owners: Toyota has refused to treat numerous problems with the EGR cooler as a design defect and a warranty claim.
As known, due to the destruction of the EGR cooler heat exchanger, coolant ingress the EGR channels and then into the cylinders. At the same time, abundant deposits (in the form of powder or crystals) form in the gas channels, often the EGR valve sticks. External symptoms - white smoke from the exhaust pipe, engine hesitation and power loss, the appearance of DTC codes (P319000, P04019C etc.), antifreeze level drops and engine overheat is possible. All this take place on cars rather new and at rather low mileage.
In general, the reason is clear - since the new generation (Dynamic Force) Toyota began to equip all the gasoline engines with high-performance EGR systems with water cooling, but did not provide for the necessary durability and corrosion resistance for real operating conditions. EGR coolers have long been used in diesel models, and internal heat exchanger leaks also occur there, but such cases are much less resonant (besides, fatigue cracks covered by the warranty are among the reasons). Also owners of hybrid 2ZR-FXE (where EGR also plays an important role) meet a similar problem.
However, in this case, Toyota decided to consider corrosion due to using of low-quality gasoline with an admixture of chlorine compounds as the cause and set out its position in the latest TSB EG-00691T-TME (02.02.2022). Repairs should be paid by the owners (the usual bill in S.Europe was $1500 as of 2021), but regional offices can provide a discount. At the same time, the service life of the new EGR cooler is also completely unpredictable.
