Known issues on the 2019 RS5 Sportback. Four recalls are on federal record for this model year. The first covers the tires: a rear axle misalignment after a prior recall repair can cause premature or uneven tire wear, raising crash risk. The second covers the 12-volt battery: an incorrect positive terminal cover fitted at the factory can compromise power in a rear crash, preventing doors from opening from the outside or the hazard lights from working. The third covers the rear suspension: a lock nut on the rear axle trailing arm can break from stress corrosion, misaligning the axle and causing a loss of control. The fourth covers the seats: a faulty cable connection to the Passenger Occupant Detection System can cause the software to misdiagnose a malfunction and disable the passenger air bag. Owners have filed 3 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're tracing a battery or air bag fault or inspecting the rear axle trailing arm, it keeps you on the OEM procedure and correct specification for your specific 2019 RS5 Sportback.
