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
Out of 15 complaints, two describe actual airbag failures: one owner's passenger-side curtain airbags deployed at 35 mph during routine driving with no collision or warning; another reported all passenger-side curtain and front passenger seat airbags deployed on the interstate with zero impact. Honda's automatic emergency system triggered in the first case. A third owner reported the SRS system failed completely, leaving airbags non-functional on a three-year-old vehicle.
The remaining 12 complaints center on repair delays for NHTSA Campaign 24V064000. Owners received recall notices but dealers have no parts available. Delays span months to 18+ months, with some dealers saying parts won't arrive until 2025. One owner reported the airbag system began short-circuiting while awaiting the recall repair, and the dealership refused to address the open recall, leaving family safety at risk. Honda and dealers confirm parts distribution issues. One owner disputed Honda's warranty denial after unintended deployment, claiming the manufacturer incorrectly cited tire impact when photographs showed none.
The cluster reveals both defective airbag behavior and a critical parts-supply failure preventing recall remedies from reaching customers.
