Recalls
Filed by the manufacturer with a regulator. A recall is repaired free of charge, whoever owns the car now.
A12/01581/24
The propellant used in the driver airbag inflator can degrade when exposed to very high temperatures and levels of humidity. If activated after an impact, excessive internal pressure may cause the inflator to burst, and metal fragments could pass through the cushion material causing injury to occupants. 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/02979/25
The structure of the airbag can deteriorate. If the airbags deploy, it could result in fragments from the inflator, injuring the vehicle's occupants. 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.
