Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering airbags on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners of 2021 Honda Accords received notice of NHTSA Campaign 24V064000 (passenger seat airbag weight sensor) but cannot get the recall repaired. Honda notified customers 12–18+ months before filing these complaints that repairs would begin by April 2024, then extended timelines another 12 months or longer. Multiple dealers confirm parts are simply unavailable and have no delivery schedule from Honda. Owners report wait times cited as 4–5 years in some cases, with Honda limiting dealer shipments to 10 units per week and conditioning supply on return of defective parts. One dealer reportedly has 2,000 customers ahead in line for the same repair. Some owners were told their cars cannot be repaired unless the airbag warning light is illuminated—a condition that may not occur until a failure happens. The HondaLink app shows the recall repair as available to schedule, but dealers cannot fulfill the appointments. No owners report actual component failure, only inability to access the recall repair. Vehicle devaluation from the open recall is cited. This is a parts supply and logistics issue, not a design defect that owners have experienced.

One of their San Diego dealers told me today that…
