Known issues on the 2021 RS5 Sportback. Five recalls are on federal record for this model year. The first covers the rear seat belt retractors, which may deactivate early and prevent a child restraint system from securing properly. The second covers the rear axle: alignment may not have been inspected after an earlier related repair, which can cause premature or uneven tire wear. The third covers the rear wiring harness, which can be missing anti-abrasion protection near the spare wheel well, risking damage to the wires in a rear crash that could disable the doors from being opened from outside and knock out the hazard lights. The fourth covers the rear axle trailing arm lock nut, which may break from stress corrosion and misalign the rear axle, leading to a possible loss of control. The fifth covers the rearview camera display, which may go blank due to a software issue and reduce rear visibility. No complaints or technical service bulletins are logged for the year. The factory diagnostic and repair procedures behind each of those systems are here.
Whether you're inspecting the rear axle hardware, checking the seat belt retractors, or tracing the rear wiring harness, this manual keeps you on the OEM procedure and correct specification for your specific 2021 RS5 Sportback.
