What's wrong?
The SRS unit in the 2018-2022 Honda Odyssey is the computer that decides when the airbags should deploy. It reads crash sensors and vehicle motion signals, then commands the side and side curtain airbags when it identifies a side impact. Those airbags are meant to protect occupants during a crash.
On affected Odysseys, the software settings for the second and third rows do not leave enough margin before deployment. Inputs from poor road surfaces, debris, or an undercarriage hit can be read as a side impact signal. When that happens, the side and side curtain airbags can deploy even though the van has not been in a side crash.
The warning sign is the event itself: an inadvertent airbag deployment. There is no separate dashboard warning or gradual symptom described before the airbags deploy.

What happens at the repair
At the dealer, a Honda technician reprograms the supplemental restraint system electronic control unit software. If reprogramming does not correct the issue, the technician replaces the ECU. The recall repair is free, including parts and labor. Honda used its general reimbursement plan on file for this campaign, so owners who already paid for related SRS ECU software or ECU work can ask Honda about documented reimbursement. Bring repair invoices or payment records to the service desk.
