2022 Honda Odyssey

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.

On October 28, 2025, the Office of Defects Investigations (ODI) opened PE25018 to investigate complaints of inadvertent deployment of the side curtain and/or side thorax air bags. These complaints concern model year (MY) 2018-2022 Honda Odyssey vehicles manufactured by American Honda Motor Co. (Honda). Honda issued recall 26V227 on April 9, 2026, to address concerns of inadvertent side air bag deployment. In the recall filing, the company stated that “[a]s of April 2, 2026, Honda has had 130 warranty claims, 25 reports of an injury, and no reports of death related to this issue from January 24, 2017 – April 2, 2026.” Honda states that the Supplemental Restraint System (SRS) Electronic Control Unit (ECU) contains incorrect deployment parameters for the side thorax and side curtain air bags, which may cause inadvertent deployment when the vehicle encounters strong road impacts, such as driving over potholes, speed bumps, or road debris. Honda stated that the SRS control logic for the second and third rows of seating contained an insufficient deployment threshold margin, allowing signal inputs to be misinterpreted as side impacts and causing inadvertent deployment of the side thorax and side curtain air bags. Recall 26V227 states that dealers will reprogram or replace the SRS ECU with improved air bag deployment parameters. Consumers received notice of this recall in late May 2026. In view of the recall being conducted by Honda, ODI is closing this Preliminary Evaluation (PE). The Agency reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

I was driving forward in the left lane, no cars in front of me. A garbage truck parked in the middle yellow lane to my left, a moving city bus on my right lane, but they were a bit further back, not driving next to me. There was a cae behind me. Was going at 25mph, then suddenly the automatic brake stopped my car. I didn’t understand why. It happened for a good 3 seconds. Then I was able to continue forward. So scary!!! No one close to my left or right or in front of me. The car behind me almost hit me because of the automatic brake.

The trunk on the van will close on its own. It does give a warning by beeping, but it’s happened at least half a dozen times. When the trunk comes down it happens quickly and has hit multiple people in the head. It’s very heavy too.

My van stalled twice and the 2nd one we need to have it towed to the dealership. The first time it stalled, we thought its only the battery and was able to run again. But the 2nd time it wont turn on even the batteries are good. The dealership diagnose it as the start/stop mechanism of the van due to the "eco" function (it stops the vehicle running when it is stop while driving) and they said that because of this they replaced the starter assembly. They even told my husband verbally that they had been getting repairs with the same issue. After they were repaired the technician verbally instructed my husband not to use the "eco function" because of the risk of stalling or breaking the starter assembly again. I learned that other Honda model such as Ridgeline and Pilot have a safety recall but why they did not include Odyssey? We have to pay out of pocket for the repairs that we did not expect coming from a good vehicle and also I bought this van brand new so I didnt expect that it will have this kind of problem at around 90K miles (my Toyota Highlander is still running at 150K!). I believe that all Honda vehicle that has start/stop "eco function" should have a safety recall, due to the fact that it can stall anytime and anywhere even when driving. Although my starter assembly had been replaced I am still anxious about this because it can lead to an accident. This is supposed to be a "family van" and Honda needs to prioritize SAFETY and RELIABILITY for a family van.

There’s been several incidences but the most recent one was today. While idling, my car fills up with a gas/exhaust smell. It happens intermittently but it has happened 4 times in the last week. If I shut the recirculate mode off, the smell will start to go away till I turn the recirculate back on. After further investigation, there’s several people with this issue as Honda odyssey owners. Problem has been reproduced several times on my own, however I will be taking to a dealership next week.

Exploding SunRoof: I was driving on the east bound 2020 freeway about 65 mph. There were no taller cars or trucks around, no overpass. All of a sudden there as a huge bang. The glass of the sunroof had exploded. It has not been used in 2 years. I cannot think of anything that could have caused it. I have only opened the sunroof once back in 2024 when I got the vehicle just to see what it was like; I haven't used it since then. When I stopped, it looked like a basketball and gone through the glass. I can't image how dangerous it would have been if the inside cover had been opened and the glass had sprayed the car. I did not get a picture of it. I drove directly to State Farm and they looked at it an approved the repair without photos.

The engine fails to restart on its own after the Auto Idle Stop (auto start/stop) system shuts it off at a stop. When this occurs the vehicle is left without power and I must shift to Park and restart the engine manually with the ignition button. This has happened while I was stopped at an intersection in traffic, leaving the vehicle disabled in a live lane until I could restart it. This is a serious safety hazard — the vehicle cannot move when traffic begins to move, and it cannot be moved out of the path of cross traffic. Honda's service campaign remedy for this condition (PGM-FI software update) was performed on my vehicle in March 2025. The failure recurred after that repair and has continued for approximately nine months. On [XXX] I returned to the selling dealer (Bob Rohrman Honda, Lafayette, Indiana, RO #[XXX]) and was charged $170 for diagnosis. The technician road-tested the vehicle, performed a battery test, and reported that the system was operating correctly with "no problem found." No cause was identified and the condition was not corrected. The failure has continued to occur since that visit. My vehicle is within the scope of NHTSA Engineering Analysis EA25004. I am filing this report because my vehicle demonstrates the specific pattern cited in that investigation: the failure persisting after the manufacturer's service campaign repair was completed. My family, including a teenage driver, operates this vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have pictures, but come to find out 2018-2024 odysseys have rear shocks that come apart at the top weld. The shock never got painted originally and they rot under the rubber boot and cause the shock to come apart into two pieces. Which causes the rear of the van to become “loose” I. Turns and bumps . Honda knows about this issue but does nothing about it
