Honda Odyssey Airbag Recall: 2018–2022 Models
Honda recall update
Certain 2018–2022 Honda Odyssey minivans are recalled because their side and side-curtain airbags can deploy unexpectedly after a strong underbody impact. NHTSA campaign 26V227000, Honda campaign UNW, lists 440,830 vehicles potentially involved. The current record says owner letters were mailed May 27, 2026; a particular van’s eligibility and completed repair still need separate checks.
Updated October 16, 2026
Why a road impact can trigger the airbags
Honda’s April 15, 2026 announcement describes deployment calibration that is too sensitive to underbody impacts. A strong impact from a pothole, speed bump or road debris can cause an unexpected side or side-curtain airbag deployment, increasing the risk of injury.
The manufacturer’s recall filing explains the control issue more precisely: second- and third-row deployment thresholds have insufficient margin, allowing acceleration signals to be interpreted as a side impact. This describes the recalled software condition; it does not mean every bump will trigger an airbag or that an owner should try to reproduce the event.
| Campaign fact | What the records identify |
|---|---|
| Model years | Certain 2018–2022 Honda Odyssey vehicles |
| Potential population | 440,830 vehicles across the campaign, not a count of failures or unrepaired vans |
| Remedy | SRS electronic control-unit reprogramming or replacement as necessary, free of charge |
| Owner notification | Letters mailed May 27, 2026, according to the current NHTSA record |
What the repair changes
The supplemental restraint system’s electronic control unit, or SRS ECU, controls airbag deployment. Honda says the remedy provides improved deployment parameters. The published remedy allows the dealer to reprogram the unit or replace it where necessary; it does not promise a new control unit for every recalled Odyssey or replacement of every airbag.
Honda directs affected owners to an authorized Honda dealer. Use campaign UNW or NHTSA number 26V227000 when arranging the visit, so the conversation concerns this particular airbag-software recall. The campaign description establishes the remedy, while the dealer must confirm the work and appointment for the individual VIN.
The mailing date is no longer a forecast
The April recall filing planned owner notification for May 25, 2026. The current NHTSA campaign record now reports that letters were mailed May 27. Those are a planned date and a later reported mailing date, rather than two different recalls. Mailing a letter does not establish that its recipient has received it or that the vehicle has been repaired.
Check the van, then check the repair record
A model-year match is a starting point. Honda’s announcement directs owners to its recall lookup or customer service at 888-234-2138 to determine whether their vehicle needs repair. Use the actual 17-character VIN rather than assuming every Odyssey from the listed years has the same status.
The NHTSA VIN search identifies unrepaired recalls; a year, make and model search provides general campaign information. NHTSA also explains that completed safety recalls do not appear in the VIN search. A result with no unrepaired recalls therefore is not a dated repair history.
For an Odyssey being purchased or already in the household, keep the campaign-specific work order with its records. Match the VIN and UNW or 26V227000 identifier, and ask the Honda dealer to confirm completion if the paperwork is unclear. A routine service visit, an unrelated recall repair or a mailed notice alone does not document that this software campaign was completed.
