SR/03711/24Safety recallInjuriesno date · EU Safety GateThe three aluminium screws of the steering box may corrode due to exposure to spray water and aggressive road-grit (salt) used for melting ice. Advanced corrosion could weaken the screws, leading to potential breakage during manoeuvring or parking. If all fixing screws fail, the power-assisted steering could detach, resulting in a loss of power steering and an increased 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.
