  1. Visual system5 Oct 2022

    2022565

    Issue: 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. Safety Risk: 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. Corrective Actions: Volkswagen will notify owners by mail and instruct you to take your vehicle to a dealership to update the infotainment software.

  2. Suspension26 Jan 2022

    2022022

    Issue: 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. Safety Risk: A tire failure could cause a loss of control and increase the risk of a crash. Corrective Actions: 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.

  3. Seats and restraints4 Aug 2021

    Issue: 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. Safety Risk: 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. Corrective Actions: 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.

  4. Suspension26 Apr 2021

    2021249

    Issue: 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. Safety Risk: Reduced vehicle stability could cause a loss of control and increase the risk of a crash. Corrective Actions: 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.
