According to Honda, the heating mechanisms in the mirror are causing the adhesive that connects the mirror glass and heating pad to the vehicle to loosen, resulting in both detaching from the vehicles. This defect involves the mirror's heating pad, which can apparently loosen the adhesive and detach itself from the mirror backing plate. If this happens, the mirror glass can also detach and fall with it, impairing rearward visibility on both sides of the vehicle.
The recall affects the 2020-2021 Honda Pilot and Ridgeline models and the 2020-2022 Honda Passport and Odyssey models. Honda changed the heater pad and adhesive tape in July 2021 to address the issue of mirror vibrations, and it believes the change has fixed any issues related to the mirror detaching from the vehicle due to loosened adhesive.
Owners will receive a notification by mail in the coming weeks, asking them to take their vehicles to an authorized dealer for inspection. Notices should be sent to owners by early May. A service technician will replace both the left and ridge mirror holder assemblies with an improved part. It will be a free fix, and owners who have already paid for these repairs could receive reimbursement.
