Known issues on the 2021 A5 Sportback. Five recalls are on federal record for this model year. The rear seat belt automatic locking retractors can deactivate early, preventing a child restraint system from securing properly. A rear axle alignment tied to an earlier suspension repair may not have been inspected, risking premature or uneven tire wear. The rear light wiring harness can be missing anti-abrasion protection near the spare wheel well, so a rear crash may damage the wires, disable the outside door releases, and knock out the hazard lights. A lock nut on the rear trailing arm can break from stress corrosion, misaligning the rear axle and risking a loss of control. And a software issue can leave the rearview camera display blank in reverse, cutting rear visibility. Owners have filed 7 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're inspecting the rear axle trailing arm, tracing the tail light wiring, or checking the backup camera circuit, it keeps you on the OEM procedure and the correct specification for your specific 2021 A5 Sportback.
