Volkswagen Group of America, Inc. has issued three separate safety recalls for various problems with multiple Audi models.

The automaker is recalling an estimated 138,896 2015-2016 Audi S3 Sedan, 2015-2019 A3 Sedan and A3 Cabriolet, 2016-2018 A3 e-tron, and 2017-2019 RS3 vehicles for an air bag-related issue.

Specifically, an improper electrical contact may cause the Passenger Occupant Detection System (PODS) to falsely detect a malfunction and deactivate the passenger air bag. This scenario increases the likelihood of injury in the event of a crash.

To fix the problem, Audi will notify owners, and dealers will replace the connector and reroute the cable, at no cost to owners.

The recall begins Aug. 18. Audi’s reference number for this recall is 69Z4

Volkswagen is also recalling approximately 126,175 2018-2019 Audi Q5 and SQ5 vehicles because the wheel arch cover trim may loosen and detach. Detached trim can become a road hazard, increasing the risk of a crash for the driver or any other any motorist who encounters it.

To remedy the matter, Volkswagen will notify owners, and dealers will secure the wheel arch trim with an additional screw and nut, at no cost to owners.

This recall begins Aug. 2 and the reference number for it is 66K6.

In a third action, Volkswagen is recalling an estimated 66 2019 Audi A8 vehicles equipped with rear relaxation seats due to a seat track issue. Specifically, the front passenger seat track rivet may fail and cause the spindle bracket to separate. This scenario increases the risk of injury during a collision.

To fix the problem, Audi will notify owners, and dealers will replace the passenger seat tracks, at no cost to owners.

This recall begins Aug. 2 and Audi’s reference number for it is 72J3.
