What is wrong

On certain vehicles, a software problem could cause the rearview camera image not to appear on the display. Canadian regulations require the rearview image to display when the transmission is shifted into reverse gear.

Why it matters

A rearview camera image that does not display could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash.

What the dealer will do

Volkswagen will notify owners by mail and instruct you to take your vehicle to a dealership to update the infotainment software.

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.

What is wrong

On certain vehicles, the passenger seat belt assemblies may contain defective automatic locking retractors (ALR). As a result, the seat belts may not properly lock to secure a child seat.

Why it matters

A seat belt that is used to secure a child restraint but is not properly locked could increase the risk of injury in 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 the seat belts. They will be replaced, if necessary.

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.
