R/2025/077
Due to a process error in the production an aluminium butyl may have been positioned incorrectly and the screw connection of the rear left and right belt buckle was potentially not executed according to the specifications. If this is the case the correct fastening of the belt buckle cannot be guaranteed. The loosening of the rear belt buckles in the event of an accident or emergency braking cannot be ruled out. This could increase the associated risk of injury.
