While sitting at light, Idle stop engaged and engine stopped - then car lost all power. I was boxed in in heavy traffic and could not move. The car could not be shifted to neutral when I tried to consider how I could get off the road. After a minute or so power suddenly returned to the vehicle and I was able to proceed. The next day, lucklily at a less busy intersection the same issue occurred (again with Idle Stop engaged). After these events I scheduled to take to dealership. Over the next several days I made sure Idle stop was not engaged and had no further issues. Took to Honda dealership and they determined started needed to be replaced. This repair was completed at my expense.

Front Camera failure which disables the entire Honda sensing Suite, Shuts down Cruise control, lane keeping assist, front collision warning and Auto emergency braking. This has caused the loss of many safety features intended to prevent accidents and injury. There are numerous warning lights on the dash that are constantly displayed and can be a distraction to other safety or maintenance concerns. Dealer has diagnosed the problem to be an issue with a faulty front camera system. The repair for this is extremely expensive

While Automatic IDLE was on, engine shut down at a red light. Dashboard showed message: put in park. Alternator was fine. Battery fine. I DID get the software update but this happened AGAIN. This time was able to put in park and was able to start the car. I have to remember to turn OFF Automatic IDLE to avoid this from happening again.

LANE DEPARTURE,FORWARD COLLISION AVOIDANCE — Filed 09/25/2026

One morning, with no prior issues, we started driving our van and it suddenly displayed several warning lights, including brake system, adaptive cruise control, auto emergency braking, forward collision warning, lane departure warning, and lane keeping assistance. We took it to Darcars Honda in Bowie, MD who diagnosed it as a front facing camera failure. The dealer replaced the camera and kept the old one. This failure in a six year old van increased the danger of collision while operating the vehicle.

The auto idle start when I am at a red light it will turn off and put it in park. I have to restart the van and put it back in drive. I believe this to be a safety issue. I have my kids with me and its dangerous. I would like to know what can be done and why hasn't this been a recall. I have to remember to push the auto idle button each time I get in to drive otherwise Im afraid ill get stranded at an intersection. Its been going on for at least a year and the dealership thought it was the battery we have replaced the battery so that is not the issue.

The power liftgate is no longer working and locked shut a few hours after multiple warning messages. There was heavy rain that night. It did randomly open and shut all or part of the way before that, sometimes after closing. This often happened after heavy rain when the van was not even in use. It could have popped open at any time, and then warning messages popped up and blocked the notifications and other dashboard information and distracted the driver. It was confirmed by the dealer and they recommended it get replaced, however, the electrical panel was corroded by water damage from a suspected leak in the roof rail. The dealer said that it would probably happen again and not to get it fixed until the leak was determined. Many others have reported this online regarding the Odyssey.

SEAT BELTS — Filed 08/02/2026

My son turned around in his second-row seat of our Honda Odyssey, causing the seat belt to cinch tightly around his waist. Even after the buckle was released, the seat belt continued to tighten instead of loosening. It became so tight that he could barely breathe, and we ultimately had to cut the seat belt to free him. There was no way to manually release or loosen the belt once it had locked. This presents a serious safety hazard. Seat belts should include an emergency release or override mechanism that allows a locked belt to be loosened during an entrapment situation.

AIR BAGS,SEAT BELTS,SEATS — Filed 04/06/2026

The rear passenger side tire hit a pothole and it caused all of the airbags to deploy on April 6, 2026. The impact should not have set the airbags off. This has caused a severe rash/burn on my son's face and neck. The vehicle is now being totaled by my insurance company and forcing me to have to purchase a new vehicle and my insurance rates to go up. Three days later, April 9, 2026, a safety recall on the over-sensitive airbags was issued for this Odyssey. There were no other warnings leading up to this. Insurance has inspected the vehicle and deemed it a total loss.

The airbag deployed unexpectedly while driving without a collision. The vehicle became unsafe to operate, and I sustained an injury. This happened last night so nothing has been inspected yet.

The rear hatch will randomly close after it is opened. The hatch will not stop closing if someone is standing under it. Several times now it has closed while someone is getting something out of the back and you can not make it stop without quickly getting out of the way and pressing the button. Both, myself and my wife have been hit pretty hard on the head by the hatch closing on us. This is a HUGE safety concern as I have children that could easily be harmed by the sheer power of this hatch. I have had the issue inspected by an independent shop and was informed that it would need both new power struts at a cost of over $1,200! The van is only 5 years old with 75,000 miles! There are no warning lights, messages or problems prior to the failure.

AIR BAGS — Filed 02/02/2025

The contact owns a 2020 Honda Odyssey. The contact stated that while driving during a snow day at approximately 15 MPH, the vehicle lost traction and crashed into a curb on the front driver's side where it came to a stop. The crash was minor. No property damage was on the curb. The air bags deployed with excessive force. No injuries were sustained. The vehicle was taken to a local independent dealer where it was diagnosed that an air bag replacement was needed. The local dealer was not contacted. The vehicle was repaired cosmetically by the insurance provider. The contact believed that the impact to the curb was minor and equivalent to going over a pothole which should not have warranted an air bag deployment. The manufacturer was notified of the failure. The failure mileage was approximately 93,000.

We hit a pot hole on a city street going 30-35 and it caused the airbags on both sides of the van to deploy. There was no damage to the van, rim, or tire. In addition, when the passenger airbag deployed my wife received a burn on her arm.

The rear hatch door closed with me standing under it and I injured my arm trying to stop the door from closing on me. The door will not stop closing even with a person there. This is very dangerous! The mechanic said that we need to replace the rear struts- this car is only 3 years old!

AIR BAGS — Filed 08/08/2020

In 2020 I was driving in Sequoia national forest and hit a small pothole/erosion hole in front of a gate at approximately 2-3mph. I slightly bottomed out the car. The airbags deployed. Mild abrasion friction burns on my wrist. My wife's airbags in the passenger seat also deployed, but since we had zero forward momentum they didn't even contact her. I was told by Honda that this is my fault and that their airbag system only deployes when it should, and ultimately just filled an insurance claim. I was extremely ignorant of how not road safe my car was, and drive it home. The car was towed for repairs. I just recently learned about this complain line, so I'm submitting now in early 2024.

I have had 2 major issues, the idle stop feature has multiple times caused my car to stall. It has even happened on the highway during traffic where the car went into idle-stop mode and would not restart the engine. Last week it happened again on a major road and the only way to restart the car is shift to park in the middle of a busy 4 lane road, turn off the car completely and then attempt a restart. The other issue was with the rear sliding door, my 3 year old son closed the automatic sliding door by pressing the button and his hand was crushed/ stuck until I was able to reopen it. I have called Honda who told me I could have it looked at but it would cost me for the diagnostic and repair if needed due to the fact that it was one month past their 3 year warranty period.
