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
The 2021 RDX carries an open NHTSA recall (24V064000) for airbags that remains unresolved. Seven owners report identical issues: they received recall notices, contacted their dealer, but repair parts are unavailable. One owner states he has been waiting over a year since early 2024 with no parts supplied or timeline given. Dealers confirm parts are not in stock, and the manufacturer has not provided a distribution schedule — though one owner was told possibly 2025.
One owner reported a design defect separate from the recall: the passenger seat has only two weight sensors, which cannot detect his 75-pound wife. The airbag stays disabled on the dashboard even when she is seated. He notes that the larger RDX sibling, the MDX, has four sensors and would register her weight. Acura stated there is no remedy available.
Another owner purchased a certified pre-owned 2021 RDX for $44,000, financed at 8.99%, only to learn immediately of the open recall with no available fix. His insurance company recommended he not drive it and warned his premium may increase. He has not driven the vehicle since learning of the recall and requested a refund and return.
