2 more faults belong to this generation. On the version page, only the ones that apply stay.
The manufacturer fixes these for free at a franchised dealer. Ask with the VIN whether it was done. The list covers the whole generation. We did not filter it by model year. Some apply only to a narrower production window.
Most recent: 7 July 2026
SR/02180/26Safety recallFire7 July 2026 · EU Safety GateThe RSW22 starter with reinforced water tightness (RWT) may experience increased abrasion of the magnetic contact, causing deposits to build up at the lowest point inside the relay. These deposits may increase relay contact resistance, leading to starting failures or short circuits. If a short circuit occurs, either when attempting to start the vehicle or while driving due to vibration-related movement of the deposits, it could cause a thermal event and increase the risk of fire. 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.
Remedy: Type of economic operator taking notified measure(s): Manufacturer Category of measure(s): Recall of the product from end users Date of entry into force: 07/07/2026
SR/00551/26Safety recallFire30 January 2026 · EU Safety GateThe failure concerns the RSW22 starter, type RWT (reinforced for watertightness). Increased abrasion of the magnetic contact can lead to the formation of deposits at the lowest point of the relay interior. This in turn can increase the resistance of the relay contact, causing accidental ignition or even short circuits, possibly leading to a thermal reaction and fire. 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.

A12/00996/24Safety recallInjuriesno date · EU Safety GateThe integrated braking system could be compromised, which could lead to an unexpected failure of the hydraulic braking assistance, thereby requiring greater pressure on the brake pedal. This can result in a longer braking distance, as well as failure of the Anti-lock Braking System (ABS) and the Dynamic Stability Control (DSC), increasing the risk of an accident. 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.

SR/01734/25Safety recallFireno date · EU Safety GateThe positive battery cable of the starter-generator may not have been manufactured correctly. This could result in a loose electrical connection, leading to excessive contact resistance. The vehicle cannot charge or start. Contact points in the starter-generator could overheat and cause a vehicle fire. 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.
