VOLKSWAGEN issued a recall on the A4, Q5, and A5 models

On certain vehicles, a power supply component within the airbag control unit may corrode and cause the unit to fail. If the airbag control unit were to fail, the airbag light would illuminate in the vehicle’s instrument panel, and safety systems such as seat belt pretensioners and airbags could be affected and may not deploy in the event of a crash (where deployment is warranted), which could increase the risk of injury to vehicle occupants. Correction: Dealers will replace the affected airbag control module.
