Recalls

Good news: Recall repairs are almost always free. Book with any manufacturer dealer and quote the recall number. Transport Canada’s own wording is that a manufacturer “will almost always make these repairs free of charge”, so being asked to pay for recall work is unusual and worth questioning. Since 2018 the Minister of Transport can order a company to pay for repairs so owners do not bear the cost.

Transport Canada recall 2022022 · manufacturer campaign 42L5

26 January 2022

Transport Canada lists: A4 2020–2021 · A5 2019–2021 · A6 2020–2021 · A7 2020–2021 · and 16 more

What is wrong

On certain vehicles, the rear wheel alignment was not checked during recall 42L1 (Transport Canada Recall 2021-249). As a result, the steering could pull to one side or another and the tires could wear unevenly. If you continue to drive the vehicle in this condition, there may be reduced traction. Eventually, a tire could fail and lose air pressure.

Why it matters

A tire failure could cause a loss of control and increase the risk of a crash.

What the dealer will do

Audi will notify owners by mail and instruct you to take your vehicle to a dealer to inspect and adjust the rear wheel alignment, as necessary. Additionally, the dealer will inspect the rear tires for premature and uneven wear due to this issue, and replace them if necessary.

Transport Canada recall 2021249 · manufacturer campaign 42L1

26 April 2021

Transport Canada lists: A4 2020–2021 · A5 2019–2021 · A6 2020–2021 · A7 2020–2021 · and 14 more

What is wrong

On certain vehicles, the lock nuts for the rear trailing arm bolts may be defective. If a nut breaks, there could be sudden changes in rear wheel alignment. This can cause a loss of vehicle stability.

Why it matters

Reduced vehicle stability could cause a loss of control and increase the risk of a crash.

What the dealer will do

Audi will notify owners by mail and instruct you to take your vehicle to a dealer to replace the rear trailing arm lock nuts. If necessary, the associated bolt(s) will be replaced as well.

Source: Transport Canada — Vehicle Recalls Database; NRCan — Fuel consumption ratings. Data current as of 6 August 2026. Running cost uses Ontario average prices (155 ¢/L, 14.5 ¢/kWh), which are hand-maintained estimates. These are average residential rates. A car’s charging is added on top of what your home already uses, so on a tiered, time-of-use or subsidised tariff it is billed at your top rate rather than this average — which makes the real cost higher, especially in the territories.
