SR/02525/26Safety recallFire31 August 2026 · EU Safety GateWater may enter the starter motor and cause damage. As a result, the engine may no longer start, or the starter motor may short-circuit or remain continuously activated. This could cause local overheating of the starter motor or thermal overload of surrounding components and lead to a vehicle fire, including when the ignition is switched off. The product does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.

Common questions
2015–2022. The changeover year can fall in two generations. If the listing is from that year, look at the neighbour too.
No. It depends on the engine and the transmission too.
The fault list is.
We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.
