Which Honda Odyssey vehicles are affected?
This recall covers 2018–2022 Honda Odyssey minivans produced between January 24, 2017, and June 3, 2022.
Honda estimates 0.1% of the 440,830 vehicles in the population carry the active defect, roughly 441 vehicles.
The issue sits inside the Supplemental Restraint System (SRS) ECU, supplied by Tier 1 manufacturer DENSO Manufacturing Tennessee, Inc. The SRS control logic governing the second and third-row airbags contains insufficient deployment threshold margin. When the Odyssey encounters a hard road impact — a pothole, a speed bump, or road debris — the resulting G-force inputs can be misinterpreted by the ECU as a side collision. That misinterpretation triggers deployment of the side and side curtain airbags even though no crash has occurred.
What drivers need to know
An inadvertent airbag deployment during normal driving is a serious event. Side and side curtain airbags deploying without warning can startle or injure occupants, particularly passengers in the second or third row who are nearest to the affected airbag zones. The Part 573 report lists no warning signs before deployment. There is no indicator light or driver alert that precedes the condition.
Honda has recorded 130 warranty claims and 25 reports of injury tied to this issue, covering the full production window from January 2017 through April 2, 2026. No deaths have been reported.
The remedy is a dealer visit. An authorized Honda dealer will reprogram or, if necessary, replace the SRS ECU with updated software carrying corrected airbag deployment parameters. The fix resolves the threshold margin issue so that road impact G-signals are no longer misinterpreted as side-impact events. There is no cost to the owner for either the reprogramming or the replacement.
Dealers were notified on April 10, 2026. Owner notification letters are scheduled to be mailed on or about May 25, 2026. Honda corrected the condition at the start of the 2023 model year on June 3, 2022, so Odysseys manufactured after that date are not included in this recall. Owners can verify whether their vehicle is affected by visiting nhtsa.gov/recalls or contacting their local Honda dealer.
Honda recall background
This recall has an unusually long investigation trail. Honda first received notice of an incident on November 15, 2017, more than eight years before the formal recall submission. Honda investigated through 2021, confirming by July of that year that under specific road conditions, the second and third-row airbag thresholds could be reached. Honda’s assessment in October 2021 concluded there were no safety concerns, and the investigation was closed.
The issue returned in October 2025, when NHTSA opened a Preliminary Evaluation (PE25-018). Honda responded in January 2026 and conducted additional market data analysis in March. On April 2, 2026, Honda formally determined that a safety defect existed and committed to a recall. The submission was filed with NHTSA on April 9, 2026.
As of April 2, 2026, Honda had logged 130 warranty claims and 25 injury reports across the affected production window. No deaths have been reported. The 25 documented injuries make this a recall where the safety stakes are concrete, not theoretical.
With 440,830 Odysseys in the population and owner letters not mailing until May 25, Honda dealers have a window before the inbound arrives. The Odyssey skews toward family buyers who tend to take safety recalls seriously, so response rates on proactive outreach are likely to be strong.

How BizzyCar can help
Owner letters won’t be mailed until May 25, which gives Honda dealers time to act first. The recall covers 440,830 Odysseys, and every affected vehicle needs to come in for a dealer visit. Owners already in a dealer’s customer database are reachable now, before NHTSA’s notification window opens.
BizzyCar’s Recall Outreach product identifies vehicles with open recalls in a dealer’s customer base and initiates two-way SMS outreach automatically. Owners receive their recall status and a direct path to schedule service, without requiring service advisors to build call lists or manage inbound manually. For Honda dealers with Odyssey-heavy customer bases, that outreach window before late May is a straightforward opportunity to pre-book service appointments before the phones start ringing.
