US auto safety regulators have closed a defect petition involving about 807,000 Honda Odyssey minivans after finding insufficient evidence to justify a formal investigation into allegations of unintended airbag deployments.
The National Highway Traffic Safety Administration reviewed a petition covering 806,963 Honda Odyssey vehicles from model years 2011 to 2017. The petition alleged that airbags could deploy while the vehicles were moving without a sufficiently severe impact or other triggering event.
The petition also alleged that the vehicles’ airbag systems could record inaccurate diagnostic information, with discrepancies between diagnostic trouble codes and the status of the supplemental restraint system.
NHTSA reviewed consumer complaints and other information involving alleged unintended airbag deployments. The agency said the reported incidents involved different types of airbags and different driving conditions, including potholes, road debris and minor curb strikes.
After examining the available information, regulators said they found no clear pattern or common factor connecting the reported incidents. NHTSA also said it was not aware of any crashes or severe injuries involving the affected vehicles that resulted from an inadvertent airbag deployment.
The petition was submitted in May 2026 and initially led the agency to evaluate whether a formal defect investigation was warranted. NHTSA’s review ultimately concluded that the available evidence did not indicate a likelihood of a safety-related defect requiring further investigation.
The decision is separate from a recall involving newer Honda Odyssey vehicles. NHTSA noted that Honda recalled certain 2018–2022 Odyssey models over airbag electronic control units containing incorrect deployment parameters. The agency said the older 2011–2017 models covered by the petition use a different vehicle platform and airbag-control system, and it found no evidence connecting the two issues.
NHTSA acknowledged that unintended airbag deployment can potentially create safety risks, including distracting a driver or injuring an occupant who is out of position. However, the agency determined that the complaints reviewed in this case did not establish a defect trend.
The petition has therefore been denied, bringing the current federal review of the alleged issue in the 2011–2017 Honda Odyssey models to a close.
