AUDI Audi A4, A5, A6, A7, A8, Q5, Q8 and Etron (2019–2021)
What the hazard is
A sudden uncontrollable movement of the rear axle cannot be ruled out and increases the risk of injury/death to vehicle occupants or other road users.
What to do
Owners of affected vehicles will be contacted by Audi Australia Pty Ltd and are asked to arrange with their nearest authorised Audi dealership to have the work carried out free of charge.
Defect
Some nuts fitted to the rear axle assembly did not meet manufacturing specifications and may break. A broken nut may lead to increased movement between the wishbone and hub carrier and a change in the wheel alignment on the rear axle.
