2021 Honda Odyssey UNKNOWN OR OTHER

Component or System Failed: Idle Stop System – The vehicle completely shuts off and requires a full restart at red lights or when stopped for several minutes. Safety Risk: The vehicle shutting off unexpectedly in traffic poses a serious safety hazard to both occupants and nearby drivers, especially when traveling with young children. I am genuinely fearful for our safety — particularly at red lights, where the risk of being rear-ended is high. There are numerous reports online of this same issue occurring in Honda Odyssey vehicles, indicating a wider safety concern. Reproduction of Issue: I have contacted both Honda and the dealership, and no effective solution has been provided. This vehicle is not safe to operate under these conditions. Inspection: The issue has been inspected by the Honda dealership, but no permanent resolution has been offered. Warning Lamps/Messages: There were no warning lights, messages, or alerts prior to the failure. The vehicle shuts off without any prior indication. Assessment of Cause: The problem appears to stem from a malfunctioning Idle Stop system, potentially related to the electrical or battery system. I understand that Honda has received multiple similar complaints from other Odyssey owners experiencing the same dangerous issue.

Dealership has been unable to complete recall repair due to parts being unavailable. The original recall is over 18 months old.

Power tailgate problem displayed on dashboard. Suddenly stopped working. Constant dinging noise when driving.

The 2021 Honda Odyssey with the VIN provided had 1) Auto Stop Idle Failure in June 2023 where the car would turn off completely at a stop (intersection, stop sign, etc.) and the car would have to me restarted. Sometimes restarting more than once. Honda replaced the car battery and conducted a software update. 2) About 7 months later in February 2024 the dashboard displayed two warnings A) Auto Engine Idle Stop System Problem and B) Charging System Problem. Honda had performed a second software update just prior to the second occurrence on 1/25/24. As of 2/15/24 Honda still has the car and is going to replace a battery sensor.

The front windshield cracked on its own on [XXX] evening around 8 pm while the vehicle was parked. I stopped at gas station to fill gas. When I was done pumping gas and sat in the car, I can hear the crack unfold and could not believe my ears and eyes. A big crack on bottom side of front windshield. Crack is smooth to touch both inside and outside but clearly visible. No object struck the windshield. The temperature was very frigid here in cleveland, ohio at that time.

My sunroof exploded on my 2021 Honda Odyssey while I was driving on the interstate, I-10 East, on Dec 16, 2023, around 4:30 pm. There was no impact from a rock or other debris. There was no rain or hail present. I was not near an overpass. I was driving and heard an explosion above me and then heard outside air like the windows were open. The center of my sunroof exploded and shattered onto my sunroof cover.

The rear lift gate will be open and then all the sudden decide it needs to be shut. Beeps really load and then come down hard and fast with no real time to recognize what is happening and get out of the way. It hurts and doesn’t stop when it hits a person

The rear view mirror on the windshield After I had the service work done for the recall, The rear view mirror on the windshield keeps breaking and hanging down. This causes hazardous conditions while driving. I took the vehicle for an oil change, and to correct the recall problem. The mirror fell apart and hung from the windshield shortly after that. The shop has confirmed that this is the part they worked on for the recall. Bisbee Honda of Danville, VA, has attempted to fix the problem 3 times. They have only been able to “stick it back together”. It causes a safety hazard as it cannot be adjusted. Meanwhile, per the service department, they initially ordered the wrong part, and failed to call me when it arrived. The (hopefully) correct part is now in backorder and per the service manager, it could be days, weeks or months. I guess it’s stuck back up with super glue or Velcro and I’ve been advised not to touch it…

UNKNOWN There is a cracking noise in engine at low speed (slow acceleration after stop). Much like this video https://www.youtube.com/watch?v=kl9D0PzOxHU&t=1s The dealer would not acknowledge it as a problem and call it by design. They say a lot of cars with this engine develop this sound. This started happening after 6000 miles.
