The 2018 Audi A4 Allroad has 3 recalls, the most serious involving the front passenger airbag, which may fail to deploy correctly in a crash or be disabled entirely, raising the risk of injury to the front passenger.
Two separate issues affect the passenger airbag. In one case, a mounting screw on the airbag module may not have been tightened enough, which can cause the bag to deploy incorrectly or not at all in a collision. In the other, corrosion on the cable connecting the passenger occupant detection system can cause the system's software to read a false fault and shut off the passenger airbag altogether, leaving that seat unprotected. On the interior side, aluminum trim strips around the door speakers on the front and rear doors can come loose over time, exposing sharp edges that could cut occupants reaching into or brushing against that area of the door.
