REASON FOR PROVIDING A NO-COST, ONE-TIME REPAIR
In some of the affected vehicles, a front door latch may open to the secondary latched position while
driving. While the door is in the secondary latched position the driver will notice wind noise from the
door and a door ajar warning will appear on the instrument cluster. This concern does not result in a
fully opened door while driving. The occupant can open the door normally using the door handle.
SERVICE ACTION
If a customer brings a vehicle in for service claiming that the vehicle exhibited this condition, dealers
are to replace both door latches. This service must be performed at no charge to the vehicle owner.
New! OWNER NOTIFICATION MAILING SCHEDULE
For the initial population, owner letters mailed on September 2, 2022. The supplement population
owner letters are expected to be mailed the week of November 27,2023. Dealers should repair any
affected vehicles that experience that experience a door opening to the secondary position, whether
or not the customer has received a letter.
