This page covers 5 recalls and 31 owner complaints for the 2017 Audi A4 Allroad.
For the 2017 Audi A4 Allroad, the dominant complaint theme centers on the passive safety systems, airbags, seats, and seat belts collectively account for the majority of the 31 filed complaints. The airbag category draws the most reports, though many of the underlying narratives are thin on operational detail, with owners noting they contacted the dealer or manufacturer without describing a specific in-vehicle event. Seat complaints include reports of heated seats overheating without any warning indicator, where owners describe feeling a burning sensation during normal use. Seat belt complaints follow a similar pattern of owners flagging concerns to dealers or the manufacturer, sometimes without a failure having occurred at the time of filing. The recurring note about parts unavailability suggests some owners were already in the service pipeline but waiting on a fix.

By System
The 2017 Audi A4 Allroad has 5 recalls, the most serious involving the restraint system: airbags and seatbelt pretensioners on certain vehicles may fail to deploy or activate in a crash, leaving occupants without full protection.
Two additional airbag concerns affect the passenger side specifically. A mounting screw on the passenger airbag module may not have been tightened enough, which can cause the bag to deploy incorrectly in a crash. On top of that, corrosion on the cable connecting the passenger seat's occupant detection sensor can cause the system to misread the sensor as faulty and shut the passenger airbag off entirely, leaving the seat unprotected in a collision.
On the exterior, a software update may have inadvertently disabled the side marker lights, so the vehicle no longer illuminates them alongside the parking lights or headlights, making it harder for other drivers to see the car at night. The remaining recall covers the aluminum trim strips around the door speakers on the front and rear doors, which can work loose and expose sharp edges that can cut occupants reaching toward or past the door panel.
