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)

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.

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

While child was seated in the rear right second-row seat of a 2022 Honda Odyssey Touring, the seat belt became stuck and jammed, trapping the child in the car seat. Multiple attempts were made to release the child but the seat belt mechanism would not release. The child became distressed and complained of difficulty breathing. As an emergency measure, the child car seat had to be physically cut and destroyed to free the child. The vehicle was subsequently taken to the dealer. The dealer confirmed that the rear right second-row seat belt was found cut in half and that the seat frame had to be replaced. Dealer stated the belt mechanism tested normal during post-incident inspection but was unable to reproduce the entrapment condition. The seat belt tensioner is suspected of having gotten stuck, causing the entrapment. This is a serious child safety incident involving potential entrapment and breathing distress in the second-row seating area.

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.

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.
