Defect investigations
Inadvertent Deployment of Air Bags
The Office of Defects Investigation (ODI) has completed its review of a Petition dated May 30, 2026. The Petition requested an investigation into inadvertent air bag deployment in model year (MY) 2011-2017 Honda Odyssey vehicles. The Petition contended that air bags can deploy absent a sufficiently severe event to trigger a deployment, such as an impact, rollover event, or G-force threshold breach. The Petition further alleged that the Diagnostic Trouble Codes (DTCs) and Supplemental Restraint System (SRS) conflict and inaccurate data is being recorded for the air bag system. An air bag is a supplemental vehicle occupant restraint system that deploys a cushion designed to inflate in milliseconds during a collision. The cushion prevents vehicle occupants from striking hard interior surfaces and, in some cases, exterior surfaces. Air bags are designed to work in conjunction with seat belts, the primary occupant restraint system. Seat belts restrain occupants keeping them in place for the air bag to provide proper protection and to mitigate injury from air bag deployment. An air bag system consists of an air bag cushion, an inflator module, an air bag Electronic Control Unit (ECU), and impact sensors. When a crash begins, impact sensors located on the vehicle exterior begin to measure impact severity. If a crash is severe enough, the sensors send a signal to the system’s ECU, which then signals the inflator to fill the air bag. ODI reviewed 9 Vehicle Owner Questionnaires (VOQs), one Early Warning Reporting (EWR) Death & Injury (D&I) report, and several TREAD (Transportation Recall Enhancement, Accountability, and Documentation) Field Reports alleging inadvertent air bag deployment in the Subject Vehicles. Several complaints allege that the inadvertent deployment of air bags occurred while traveling over potholes, road debris, or during minor curb strikes. All the complaints allege that there was no warning prior to the inadvertent deployment. In general, different types of air bags are designed for different types of impacts. For instance, frontal air bags are generally designed to deploy during frontal impacts; side curtain air bags are generally designed to deploy both during rollovers and impacts to the sides of the vehicle; and side thorax air bags are generally designed to deploy during impacts to the sides of the vehicle. While these are broad categories of crash scenarios, the specific conditions under which deployment is intended are multifaceted and dependent on complex algorithms. Differences in particular variables can make a deployment an intended part of the design in one scenario and not in another similar scenario. Although the reports described above all contain allegations of inadvertent deployment, the conditions under which those reported deployments occurred differ widely. The reports ranged different types of air bags, different combinations of air bags, and different driving scenarios preceding the deployment. Based on the data available to ODI, there is no clear pattern or factor to prompt the alleged inadvertent deployments. Thus, ODI’s review did not identify a trend of a vehicle defect regarding any type of air bag in the Subject Vehicles. Moreover, ODI did not identify any reports of inadvertent air bag deployment that resulted in a loss of vehicle control. ODI is likewise not aware of any crashes or severe injuries involving the Subject Vehicles that resulted from inadvertent deployment of the air bags. ODI recognizes that inadvertent air bag deployments can create dangerous safety hazards. For instance, an inadvertent deployment can surprise a driver, leading to a loss of vehicle control; or if an inadvertent deployment occurs when an occupant is out of position, the force of the deployment may injure the occupant. Inadvertent deployments have been the basis for past the federal safety agency recalls and investigations. Here, the Petition cites one such recall: Recall 26V‑227, which concerns inadvertent deployment of the side curtain and thoracic air bags in MY 2018 to 2022 Honda Odyssey vehicles (the “Recalled Vehicles”) due to the air bag ECU containing incorrect deployment parameters. Although this recall involved Honda Odyssey vehicles in adjacent model years to the Odyssey vehicles that are the subject of this Petition, ODI understands certain key differences to exist between the two groups of Odyssey models. Honda introduced a new generation of the Odyssey line in 2018. This new generation involved a large-scale redesign and a new vehicle platform compared to the previous model years. As a result, the vehicles covered by the Petition differ from the recalled vehicles in many characteristics, including physical dimensions, engines, transmissions, and air bag ECU algorithms. Given these differences, ODI’s review has not identified evidence that the reports of inadvertent deployment in the Odyssey models covered by the Petition correlate to Recall 26V‑227. After thoroughly assessing the material submitted by the Petitioner, consumer complaint information in the federal safety agency’s databases, and other relevant information already in possession of the Agency, the federal safety agency has not found sufficient evidence to indicate that a trend of inadvertent air bag deployments as alleged by the Petitioner is likely to present a safety related defect that would warrant a formal investigation. After full consideration of the available information the Petition is denied. A denial report will be posted in the Federal Register. The closing of the Petition does not constitute a finding by the federal safety agency that a safety related defect does not exist, and the agency reserves the right to take additional action if warranted by future circumstances. The Petition can be viewed at under ODI Number 11744118.

Vehicle Information:Year/Make/Model: 2015 Honda Odyssey EX-L VIN: [XXX] Mileage: Approximately 45, 200 miles Component / Defect: Engine Oil Leak leading to Alternator Failure (Front Spool Valve / Valve Cover Gasket Leak onto Alternator) Summary of Incident and Service History: My car overheated and would not start on several occasions over the last year and a half starting in July 2025, leaving me stranded and requiring it to be towed. My car has been in service at the dealer multiple times for approximately 2 weeks each time. Oil Leak and Alternator Hazard: The vehicle experienced engine oil leaking directly onto/into the alternator. According to communications from Honda service personnel ([XXX]), oil leaking from the front spool valve and valve cover gaskets penetrates the alternator, causing component failure. The dealership explicitly warned that failure to complete these repairs would result in repeated alternator failure. XXX Service: The vehicle was brought in for diagnostic work and repairs at Brickell Honda Performed services included diagnostic procedures, engine oil & filter replacement, radiator fan motor replacement, A/C condenser fan motor replacement, and tire rotation. Total Paid: $2,443.60 Additional Repair Estimates Provided: Valve cover gaskets & spark plug replacement: $1,901.18 plus tax Front spool valve replacement: $1,641.70 plus tax Prior Related Invoices: An earlier invoice was issued on XXX for $2,096.29 by Brickell Honda for alternator replacement and other maintenance services. Safety Risk Statement: An unaddressed oil leak dripping onto the alternator poses a serious electrical component failure hazard while operating the vehicle. Sudden loss of electrical power while driving can cause engine stalling, loss of power steering, loss of headlights/lighting, and disablement in traffic, presenting a significant risk of collision and vehicle safety hazard.

I am reporting suspected odometer tampering / odometer fraud. Vehicle: 2015 Honda Odyssey Touring Elite VIN: [XXX] Current odometer displayed: ∼96,xxx miles Actual mileage per history: 215,407 miles Seller Information: Name: "[XXX]" Phone: [XXX] Location: [XXX] Platform: OfferUp URL: [XXX] Evidence - CARFAX Report (attached) On XXX CARFAX shows two entries on the same day: XXX - 215,407 miles - Source: Auto Auction - Vehicle offered for sale / Vehicle sold XXX - 96,320 miles - Source: California Inspection Station - Passed emissions inspection - Flagged as MILEAGE INCONSISTENCY On XXX, same day, California DMV shows Title issued / New owner reported (Owner 2). CARFAX Additional History shows Owner 1 = Mileage Inconsistency, Owner 2 = No New Issues. The vehicle lost 119,087 miles between the auction sale and the smog check on the same day, before the new title was issued. This indicates the odometer was rolled back after purchase at auction and before obtaining a smog certificate to obtain a clean title as Owner 2. This appears to violate California Vehicle Code XXX (unlawful to disconnect, turn back, reset odometer with intent to alter mileage) and Federal Odometer Law 49 U.S.C. § 32703(2) and § 32705. Attached: Full CARFAX PDF for VIN [XXX] showing 215,407 and 96,320 entries Screenshots of seller's ad showing current listed mileage at ∼96k Please investigate. I am available for follow-up.

My rear passenger sliding door is stuck open and won't close.
2015 Honda Odyssey Touring Elite, VIN [XXX]. Vehicle was involved in a frontal collision on XXX. The driver's frontal airbag did not deploy. During the impact, I was thrown forward and struck the steering wheel. Additionally, a side/sliding door opened during the collision. The door was closed before the collision. I am concerned about possible failures of the supplemental restraint system and door-latching system. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2015 Honda Odyssey. While the contact's fiancé was driving 30 MPH with the contact seated in the passenger's seat, the passenger's side air bag deployed without impact. The contact sustained injuries to the right arm and neck. Medical attention was provided. The air bag warning light was not illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 221,092.
I first experienced an engine misfire in February 2025. The vehicle had a P0301 misfire code, and at the time I was unaware of Honda’s extended warranty related to this issue. We had a trusted mechanic friend inspect the vehicle and replace the spark plugs and ignition coils. He noted that there was significant carbon buildup. After those repairs, the vehicle appeared to run normally, and we believed the issue had been resolved. Later, I received Honda’s extended warranty notice and realized that the issue I experienced may have been related to the condition covered by the warranty. I contacted my local Honda dealership in August 2025 and explained the prior misfire, repairs performed, and the warranty notice I had received. However, because the check engine light was not currently illuminated, I was told there was nothing that could be done unless the vehicle was actively displaying the issue. I also contacted Honda Corporate regarding this matter. I was advised that reimbursement for some of the repairs I had already completed might be possible, but that it would need to be reviewed. I chose not to submit those receipts at the time because I was concerned that doing so might impact my ability to use the extended warranty coverage if the problem returned. Unfortunately, the issue appears to be progressing. On June 2, 2026, the vehicle set a P3400 code, which is related to the Variable Cylinder Management (VCM) system. At that time, the oil level was low. After adding oil and completing several driving cycles, the check engine light turned off. However, the vehicle continues to consume oil at an alarming rate. I have had to add additional oil again in July. The problem is progressing - it is the issue that should be covered by warranty but holds refuses to do anything because the light isn’t currently on,
American Honda Motor Co., Inc. issued an official Warranty Extension in July 2025 covering engine misfires from piston ring deterioration (DTCs P0301-P0304) on 2013-15 Pilot and 2013-17 Odyssey vehicles. My 2015 Honda Odyssey (VIN: [XXX]) experienced this exact defect, resulting in severe engine misfires and secondary alternator failure caused directly by engine fluid saturation leaking onto it from the primary defect. I paid $5,275.80 for repairs prior to campaign awareness (Invoices XXX and XXX). I submitted complete reimbursement documentation on January 31, 2026. Honda has withheld my funds for 178 days (which is 122 days past their promised 8 week deadline) while corporate customer care agents falsely claim payment is “approved but pending final management sign- off.” I have called 11 times and corporate managers who are never available HAVE NEVER returned my calls like the representative with Honda I've spoken with each time assures. This deliberate delay subverts federal safety campaign integrity and artificially manages liability exposure. Request immediate enforcement action for an ongoing corporate warranty evasion pattern.

I drove very slowly over a speed bump by my local public high school and my airbags deployed. My hand was burnt from the airbag, my insurer gave me 14K + to repair the car, but that was not enough and so I took the money and bought a different car. furthermore because of this , my insurer increased significantly my monthly premium. My young children were in the car and were terrified. My insurer also only paid for a certain amount of days with the rental car, and I had to pay out-of-pocket for the other days.
Odometer Fraud. The contact purchased a 2015 Honda Odyssey. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 150,000. After reviewing a Carfax report, it was discovered that the mileage was 154,000.
