• Visual System#2022565October 5, 2022

  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.

• Suspension#2022022January 26, 2022

  4,361 units affected

  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.

• Airbag#2021688November 10, 2021

  35,107 units affected

  Issue: On certain vehicles, the passenger occupant detection system (PODS) may malfunction. This could cause the airbag system to turn off the passenger-front airbag even when a passenger is seated. Note: This problem would cause an error message to display on the instrument panel and a warning chime to sound. The airbag indicator light would also display "passenger airbag off". Additional note: For the 2020 model year A5 model, only the A5 Sportback is affected by this recall. Safety Risk: An airbag that is turned off could increase the risk of injury to a passenger in a crash. Corrective Actions: Audi will notify owners by mail and instruct them to take their vehicle to a dealer to inspect the front passenger seat. Depending on the seat type, the dealer will either replace the seat heating mat including the connecting cable or the entire seat cover.

• Seats And Restraints#2021486August 4, 2021

  7,198 units affected

  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.

  5,396 units affected

  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.

  Issue: On certain vehicles, the passenger occupant detection system (PODS) may malfunction. This could cause the airbag system to turn off the passenger-front airbag even when a passenger is seated. Note: This problem would cause an error message to display on the instrument panel and a warning chime to sound. The airbag indicator light would also display "passenger airbag off". Safety Risk: An airbag that is turned off could increase the risk of injury to a passenger in a crash.

• Fuel System#2015018January 16, 2015

  3,174 units affected

  On certain vehicles, a fuel leak may occur in the fuel injection system under certain driving conditions.

• Airbag#2014477October 23, 2014

  15,116 units affected

  On certain vehicles, it is possible that the front airbags may not deploy in a crash as designed, due to an improper algorithm/coding within the airbag control module. Front seat occupants may not have the intended protection from the frontal airbag system in crash events where second stage deployment is warranted. This could increase the risk of injury to the front seat occupants. Correction: Dealers will adjust the airbag control unit deployment parameter.
