Honda Recalls 440,830 Odyssey Minivans Over Airbags That Deploy on Potholes

Honda is recalling 440,830 Odyssey minivans after a software flaw in the airbag control system can cause side and side curtain airbags to deploy unexpectedly when the vehicle hits potholes, speed bumps, or road debris — with regulators linking the defect to 25 injuries and 130 warranty claims. The recall covers 2018–2022 model year Odysseys manufactured between January 24, 2017, and June 3, 2022, and was filed with the National Highway Traffic Safety Administration (NHTSA) on April 9, 2026 under Campaign No. 26V227. Dealers will reprogram or replace the airbag control unit at no cost to owners.

What Is Causing Odyssey Airbags to Deploy Without a Crash?

The problem sits inside the Supplemental Restraint System (SRS) electronic control unit (ECU), supplied by 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, triggering side and side curtain airbags to deploy even though no crash has occurred.

The recall remedy involves programming the airbag module with updated parameters that were introduced into production by DENSO in June 2022 and installed in model year 2023 and newer Odyssey minivans. In other words, Honda already fixed the problem in newer vehicles — this recall brings older ones up to the same standard.

NHTSA estimates that approximately 0.1% of the 440,830 vehicles in the recall population actually carry the active defect — roughly 441 vehicles. That percentage is small, but an airbag deploying without warning at highway speed or in a school zone is an immediate safety event regardless of how rare it is.

Honda Knew About This Problem as Far Back as 2017

Honda first received notice of a related incident in November 2017, nearly nine years before this recall. Honda investigated and confirmed by July 2021 that road impacts could trigger the second and third-row airbags. Despite that finding, Honda concluded in October 2021 there were no safety concerns and closed the investigation.

The issue came back onto NHTSA’s radar in October 2025, when the agency opened a Preliminary Evaluation after receiving 18 consumer complaints about inadvertent airbag deployments. Honda conducted additional analysis in early 2026 and formally determined a safety defect existed on April 2, 2026.

In a stark warning, safety regulators also noted that Honda may have been aware of the defect for more than five days before formally reporting it, which could raise concerns under federal laws governing the timely disclosure of safety issues and could expose the company to civil penalties.

Who Is at Risk and What Can Happen

Side and side curtain airbags are designed to protect passengers in the second and third rows during an actual side-impact crash. When that system activates unexpectedly during routine road shocks, the risk becomes immediate and highly personal — especially in a minivan that often carries families.

As of April 2, 2026, Honda recorded 130 warranty claims and 25 reported injuries linked to the issue. No fatalities have been reported. Potential harms from an unexpected airbag deployment include facial and upper-body injuries, loss of vehicle control, and harm to unrestrained children or rear-seat passengers in close proximity to the deploying curtain airbag.

What Odyssey Owners Should Do Right Now

Step 1 — Check your VIN. Enter your 17-character vehicle identification number at NHTSA.gov/recalls or recalls.honda.com to confirm whether your specific vehicle is included. VIN-based lookup tools became available in mid-April 2026.

Step 2 — Schedule a dealer appointment. Contact your nearest authorized Honda dealer and request service for Recall Code UNW. The repair — reprogramming or replacing the SRS ECU — is free of charge. You do not need to wait for a notification letter to schedule service.

Step 3 — Watch for your mailed notice. Honda has committed to notifying owners through mail, with notification letters expected to be sent out by May 25, 2026.

Step 4 — Call Honda’s hotline with questions. Reach Honda customer service at 1-888-234-2138 (Recall Code UNW). If you have trouble reaching your dealer or scheduling service, contact the NHTSA vehicle safety hotline at 1-888-327-4236.

Step 5 — Seek medical attention if you were injured. If you or a passenger experienced injuries from an unexpected airbag deployment before this recall, speak with a healthcare provider and document the incident. Contact Honda’s customer service line to report the event.

Step 6 — Note the stop-sale order. A stop-sale order has also been issued for impacted units currently in dealership inventories. If you are currently shopping for a used 2018–2022 Odyssey, verify that the recall repair has been completed before you purchase.

Regulatory & Legal Context

This recall is overseen by the National Highway Traffic Safety Administration (NHTSA) under Campaign No. 26V227. Consumer Reports has noted that Honda may have been aware of the defect for more than five days before filing the required NHTSA report, which could expose Honda to civil penalties.

Honda is not currently facing legal action specifically tied to this Odyssey recall. However, Honda is separately facing a lawsuit accusing the company of knowingly selling Prologue electric vehicles with defective front drive axles that pose a safety risk. Airbag-related recalls of this scale have historically drawn class action attention, particularly when an automaker’s prior knowledge of the defect becomes part of the public record.

Frequently Asked Questions

Which vehicles are affected?

 The recall covers 2018–2022 Honda Odyssey minivans manufactured between January 24, 2017, and June 3, 2022. No other Honda models are included in this recall action.

How do I know if my Odyssey is part of the recall?

 Enter your 17-character VIN at NHTSA.gov/recalls or recalls.honda.com. VIN lookup tools for this recall became available in mid-April 2026.

What should I do if my airbags already deployed while driving?

 Stop driving the vehicle if it is unsafe to operate, seek medical attention for any injuries, and report the incident to Honda at 1-888-234-2138. Document the date, location, and road conditions. You may also file a complaint directly with NHTSA at SaferCar.gov.

How do I get the repair done, and what will it cost? 

Owners of affected vehicles should visit an authorized Honda dealer to have the SRS ECU reprogrammed or replaced at no cost. Bring your VIN and reference Recall Code UNW when you contact your dealer.

Who regulates this recall?

 The National Highway Traffic Safety Administration (NHTSA) — the federal agency responsible for vehicle safety in the United States — is overseeing this recall. The official NHTSA record is Campaign No. 26V227 and is searchable at NHTSA.gov/recalls.

What are the specific risks? 

Airbags that deploy unexpectedly can increase the risk of injury. Second and third-row passengers — including children — are closest to the affected side curtain airbags and face the greatest risk of impact injury or startled driver response that could cause a secondary accident.

My Odyssey is a 2023 or newer — am I affected?

 No. Honda corrected the defect at the start of the 2023 model year on June 3, 2022, meaning newer Odysseys are not affected by this recall.

I’m buying a used 2018–2022 Odyssey — what should I check? 

Before purchasing, enter the vehicle’s VIN at NHTSA.gov/recalls to confirm the recall repair has been completed. A stop-sale order has been issued for impacted units currently in dealership inventories, so any dealer-sold 2018–2022 Odyssey should have the repair on record before the sale closes.
