The internal clearances of the low pressure fuel pump are small, so the friction is high and the pump is sensitive to vapour lock. The cause lies with the supplier: in June 2021 it changed the manufacturing process, and the new process did not hold the dimensions reliably.

The fault comes out when the fuel is low, or when the tank warms up in hot weather. Fuel pressure is then lost, the engine does not get enough fuel and can stop while driving. The authority calls this a loss of motive power, and it is the most serious consequence a fault can cause while under way.

The milder sign is hesitation at part throttle and sluggish acceleration, and the fault is reported above 40 000 kilometres.

In July 2025 the maker issued a recall for it under number 25S75 (25V455 at the authority), and it covers 850 318 cars from the 2021 to 2023 model years. One thing has to be known, though: when the campaign started the final repair was not yet ready, and owners first received only an interim notice. On an affected car it is therefore not enough to ask whether the recall has been carried out; it also has to be clarified whether there was anything to carry out.
