The accumulator in the driver/passenger head airbag inflator can leak, preventing the airbag to fully deploy if activated in an accident, impairing the protective effect of the airbag. Moreover, the accumulator can detach, entering the interior of the vehicle or becoming detached from the vehicle. This can lead to an increased risk of injury for passengers and/or other road users. 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.
