Equipment Problems of Honda Odyssey - part 1

Vehicle suddenly starts having multiple lights and warnings come up such as road departure mitigation, adaptive cruise problem, collision mitigation, auto high beam, etc. Reading online it seems multiple people with Honda oddysey are experiencing the same issues.

On 3 separate occasions, I have been at a stop light where the auto stop kicks in. When I release my foot from brake, it should auto start. Instead, it stalls out. This is a huge safety issue and has caused cars behind me to get angry and honk. If someone wasn't paying attention, this could cause collision easily. The battery seems fine, and even if it wasn't, shouldn't the battery life be considered when the feature is triggered? I will be taking it in to get serviced, but I'm very frustrated.

When I am stopped at an intersection, my 2025 Honda Odyssey will often automatically stop the engine as part of its auto idle feature. However, three times in the last month, my car has stalled when it's time to start the engine. One time was on a highway when I was stopped at a light, and cars started honking and driving around me (including on the shoulder). Only after I turn the car off and turn it back on, can I start driving again.

I was in a single vehicle car accident on Monday may 4th 2026 right at 6am central standard time. My 2019 Honda Odyssey has been totaled out by insurance. Primarily all of the damages were on the front driver side, the air bags on both the steering wheel and under the steering wheel deployed but the side curtain airbag didn't not, and Honda link also wasn't able to connect to emergency services once a crash was detected. The side curtain air bag not deploying has been pointed out and brought to my attention by almost every single person who has seen my vehicle since the accident. During the accident I swerved to avoid an animal that was running across the road and I over corrected and loss control and in a complete panic it has been assumed by everyone including myself that I accidently pressed the accelerator pedal instead of the brake.

The auto idle stop feature caused the engine to shut down twice, both times at a stoplight.

Transmission slow to respond when accelerating from a stop, also when going from reverse to drive the transmission is also slow to respond, causing interruption in that moment of traffic. The possibility of causing an accident. The incident has not been confirmed by a reputable dealer. Also, it has not been inspected by a reputable Honda dealer. There has not been any warning lights on regarding the delayed transmission shifting.

I have encountered several instances where the vehicle goes idle at a spot light as expected. However the vehicle fails to restart when letting off the brake. Instead, the vehicle shifts into park. Once the vehicle shifts into park, I am unable to shift into drive. I must restart the vehicle and try en shift into drive. This is extremely dangerous and has happened multiple times. This vehicle is one year old and has 9k miles.

The engine shuts off completely when at a stop after releasing the break pedal. This occurs when the idle auto start is on forcing me to restart the car multiple times with the engine button until it turns on and I am able to continue driving. This is a safety hazard because it happens during traffic and an accident can occur. I have taken it multiple times to the dealer with no replication being able to be done.

I own a 2020 Honda Odyssey and I am currently having a safety issue with the power tailgate. Upon inspection by my Honda dealership, my vehicle requires a new power tailgate control unit and floor harness and my roof rail and clips need to be re-sealed and replaced. It was discovered that due to the break in seal the connectors corroded due to a water leak. In April of 2026 I received multiple warning messages on my dashboard. The first was power tailgate problem and the second was keyless remote problem. At first I noticed my car continuously beeping while driving along with the warning on my dashboard. I attempted to turn the vehicle off to see if it would reset, but it did not. I attempted to open and close my tailgate. I could only open my tailgate with the push button on my dashboard. I had to manually close my tailgate due to my buttons on my car and my key fab failing to work. Next while driving, I could hear the locking mechanism on my tailgate continuously locking and unlocking. Of course this particularly concerned me because I have 3 young children and their safety as well as mine was in danger. It was unclear if my tailgate was going to open while driving. Such an action could potentially cause a serious threat or harm to myself, my family or other vehicles on the road.

I've had several incidents of my car stalling occur since the purchase of the vehicle over the span of 16 months, probably around a dozen times or so. I will stop at a stop light and the vehicle's idle-stop system does not function properly. The vehicle shuts off but does not auto-restart. When I try to manually restart, nothing happens. There have been times where it took several times before the vehicle started back up. Even more seriously, I've stopped in the middle of traffic and the same thing happened. We have had a couple of very scary incidents of cars having to move over a lane to pass our idle vehicle. Thankfully no car hit us due to our idled vehicle. We have owned this vehicle for less than 1. 5 years and have had two battery replacements. I've also had the vehicle not start from my garage or parking lot. When I try to start the vehicle a second time, there are times where the start button feels very firm and doesn't push down easily. I have to push the start button several times before the vehicle starts. I'm grateful there have not been any major accidents occur but this is an extremely unsafe situation for the driver and their passengers.

This has been an ongoing issue with the sensors on the sliding door. When closing the door, it would start to close half way, then opens. This makes it really unsafe for children or anyone sitting next to the door as it would open unexpectedly or not close all the way without having to physically pull the door to close. When walking away from the vehicle, sometimes the car would lock automatically (as it should) but there are also times where the door would automatically open when walking away and things has been stolen from the vehicle because of it. The sensors on these sliding doors has been a real safety issue.

The car will lose power while sitting at a red light. The dash lights up and you can't do anything. You have to turn it off and back on and hope no one hits you in the meantime. This has happened twice now. I bought it brand new, serviced regularly and has 16k miles.

Issue with the idle auto star stop. I was driving on the freeway traffic stoped and I press fully down on the brakes and the turned of in stop and go traffic. Took about 5 minutes press and depress the brake pedal for the system to active again.

2024 Odyssey sport VIN [xxx] in the drive through lane at a reataurant activated the auto start stop feature and shut off the van. The van did not restart when trying to move foreward again and had to cycle the starting ignition system via placing van in park and pressing the start button. Taking the van to the hennesey Honda dealer in woodstock GA for inspection. Thank you [xxx] [xxx] [xxx] or [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Idle start stop system was engaged at stop light. When I released the brake the van engine should have restarted - however the van completely died at this point. I had to wait about 10 seconds and then restart the entire car while sitting at the stop light. Very dangerous - the vehicle has also done this when at a stop light but cut off after I started to make a turn - leaving me in a dead vehicle in traffic's way -.

Description: subject: formal warranty claim – spontaneous glass breakage and request for immediate assistance serious and unexpected failure involving my vehicle, a 2025 Honda Odyssey elite (VIN: [xxx] ), currently with approximately 26,000 miles. On April 19, 2026, I submitted an initial complaint to Honda concerning what appears to be a spontaneous breakage of the rear side (fixed quarter) glass. The vehicle was parked overnight in driveway when the glass shattered without any known impact, external force, or evidence of vandalism. The fracture pattern is consistent with spontaneous tempered glass failure originating from the edge, which raises concerns of a potential manufacturing defect or internal stress within the material. On April 20, 2026, I presented the vehicle in person at my local Honda dealership for inspection and assistance. To date, no action has been taken, nor has any resolution been provided. This lack of response is unacceptable given the safety implications. Due to safety concerns, the vehicle is currently not in use and remains parked. I am unwilling to operate the vehicle in its present condition out of concern for further damage or risk. As a result, I am experiencing a significant disruption to my daily activities and mobility. Accordingly, I respectfully request the following: 1. Immediate review and approval of this issue under Honda’s warranty as a case of spontaneous glass breakage. 2. Prompt authorization for repair or replacement of the damaged glass at no cost to me. I have photographic documentation available. Sincerely, [xxx] [xxx] [xxx] ?VIN: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

This is the fifth time the auto engine shutoff failed to restart after I stopped my car at a stoplight or traffic. This results in potential rear ended accident as one time it stopped in the middle of traffic on the freeway, another time the car behind me at a right turn light that turned from red to green almost rear ended me. No, I brought the car to Honda dealership and they said no problems. But this auto engine shutoff that failed to restart has occurred fifth times. Vehicle has been inspected by dealer and unable to reproduce because they didn’t drive it and step on the brake and have it stopped in middle of traffic. There was an engine warning light that occurred twice but disappeared after 1-2 days before my scheduled dealership appointment. I mention this to dealer. The failure happens suddenly without warning once I step on brake without turning off the auto engine shutoff which I sometimes forget because it is every single time I turn the engine off the auto shutoff would reset. I called Honda America back in January 2026 when I had this problem. I changed my car battery already and so it is not a car battery issue.

Power tailgate problems caused by water leaking through body seams. A visible gap in the rear hatch allows water to flow into the vehicle and shorts out control module. This has ruined my control module, caused mold and I noticed a burning smell.

Sunroof spontaneously exploded while driving. No object hit the sunroof.

The issue involves a malfunction of the auto start/stop system in my 2025 Honda Odyssey, where the engine fails to automatically restart after coming to a stop. The vehicle instead requires a manual push?button start to regain engine function. The vehicle and all related components are available for inspection upon request. This failure created a significant safety risk, as the vehicle became unexpectedly inoperative in active traffic. Losing propulsion at intersections or stop?and?go conditions exposes occupants and surrounding drivers to the risk of a rear?end collision or being stranded in a hazardous location. The problem has not yet been reproduced or confirmed by a dealer or independent service center, but it has occurred during normal operation. The vehicle has not been inspected by the manufacturer, police, insurance representatives, or other third parties regarding this specific failure. There were no warning lamps, messages, or prior symptoms before the failure occurred. The issue first appeared without any advance indication.

On 4/4/2026, my child sustained a serious finger injury involving the power sliding door. The child activated the power sliding door using the interior door button. While the door was closing, the child’s hand remained on the front (leading) edge of the sliding door where it meets the door frame (b-pillar). The child’s finger became caught between the closing door and the frame. The power sliding door continued to close completely and latched shut on the child’s finger. At no point did the door stop or auto-reverse, and there was no noticeable slowing, hesitation, or warning indicating obstruction detection. The door operation sounded normal during closing. The child’s finger remained trapped until an adult manually opened the sliding door to release it. The injury involved a finger amputation involving the distal portion of the finger with an open fracture and nail involvement, requiring emergency room treatment. Emergency department records document a diagnosis of fingertip amputation, with radiology findings noting a soft tissue amputation defect and concern for distal phalanx (tuft) fracture of the affected finger. Follow-up evaluation on 04/06/2026 confirmed the severity of the injury and resulted in an urgent same-day referral for orthopedic/hand surgical evaluation.

Trunk is flooding when it rains.

My husband and I are driving down the road to go to the store and the sunroof exploaded there was no car in front or behind us for something to of had hit it. It just burst into pieces.

When stopped at a red light, the vehicle’s auto off system turned the engine off. When the light turned green and I removed my foot from the brake, the engine stalled and would not restart. I pushed the start button several times, put the vehicle in park, pushed the start button a few more times, and finally got it to restart. Luckily, this happened leaving my neighborhood and not in a more precarious situation. This has happened approximately 20 times now. I’ve had the vehicle inspected by the dealer. They could not replicate the issue, but acknowledged that Honda knows it is an issue. They aren’t willing to fix it until there is a recall on the vehicles. In the meantime, I have a one year old vehicle that sputters and struggles to restart more often than not. I have had the vehicle stall like this after the auto off system turned the engine off when trying to merge into traffic on the interstate. I had a near miss to an accident at that time because the vehicle stalled and would not restart.

Right slide door problem on dashboard. Continues to beep and blink right slide door problem while driving. The door will not open when stopped and in park.

Car leaks. Cargo bay fills with water. Possible mold issues. I am told this leaking causes damage to the control module for the tailgate. Our tailgate will close on us and has almost closed on our children. We have to be very careful when the children are around the tailgate because it will begin to close without warning.

I am writing to formally report an issue with my 2018 Honda Odyssey. I recently discovered water seepage in the rear trunk area, which has caused moisture buildup and potential interior damage. After researching the issue online, I learned that many other 2018 Odyssey owners have reported the same water?leak problem, indicating that this may be a known manufacturing or design defect. Despite similar complaints, I have not seen any acknowledgement, recall, or official response from Honda addressing this issue. As a long-time Honda customer, I am disappointed that such a significant problem—one that can lead to corrosion, mold, and electrical complications—has not been proactively addressed. I am requesting: an inspection and repair at no cost, as this appears to be a widespread defect. Clarification on whether Honda is investigating or planning to address this known issue. Assurance that any related damage caused by the water seepage will also be covered. I take pride in maintaining my vehicle, and I expect a reliable, defect-free experience from a brand like Honda. I hope Honda will take this matter seriously and provide a prompt resolution.

Auto off system malfunctioning at stoplights. Happened 4 times in 10 days. Remove brake to accelerate and van is no longer in drive. Dash says to depressed brake to engage drive. Do this and will not go into drive. Need to turn vehicle off and back on to be able to place van in drive. One time it would not engage in drive and was able to depress brake and get back in drive but dash kept flashing “brake. ” afraid I will get rear ended at a stoplight.

I was commuting home, about 30 minutes into the drive, all of the dashboard and radio went blank for a few seconds. It came back on and the break light, anit-collision, lane departure, lights were all flashing. It did this 2 more times in the over the next 5 minutes. I was concerned for my safety because I wasn't sure if my breaks and all the other things were working propoerly. I didn't know how fast I was going or if my car was going to stall on the highway. I see that a recall was issued by Honda yesertday, not for my car model, but a similar issue (a software bug can cause the instrument panel and rear-view camera to go blank). It has not yet been inspected by a repair person. There wre not any warning lights prior to this happening.

Several times, I have been driving, and the auto stop shuts the engine down, then it will not restart. This has happened on a very busy state route in the middle of an intersection, while I have my young children in the vehicle. This is very concerning and a mojor safety issue for us.

One week ago, I was driving on a highway, accelerating to the 65 mph speed limit on that road, my van's accelerator completely stopped responding. Despite pumping the pedal repeatedly, I was unable to control my speed at all, and the car continued to lose speed. I had my three children in the car at the time, and given that people regularly go in excess of 70 mph on that road, I was in danger of not being able to exit the road and/or being hit. I was able to coast off of onto an exit, and the car started responding at speeds of 30 mph, but it was lurching and jerking while driving. We immediately had the vehicle inspected by an independent mechanic and have been advised that the transmission needs to be replaced. There were no warning lights for this failure. The car also had an incident about a year ago where all lights came on and it stopped responding. At that time, we had Honda dealership examine it, and they said they could not find any issues. Additionally, the car has been jerking slightly while shifting, but the issue improved when we had the transmission fluid flushed at the Honda dealership again about a month ago, and no issues were noted by them at that time. We have performed regular maintenance and safety inspections on this vehicle.

He driver-side power seat adjustment system is malfunctioning. When attempting to adjust the seat position, the seat adjustment motor can be heard running; however, the seat frequently becomes stuck and does not move as intended. At times, only one side of the seat moves during adjustment, causing the seat to shift unevenly or become misaligned. This condition affects the ability to properly adjust the driving position and may impact driver comfort and control of the vehicle, which could pose a safety risk while operating the vehicle. The problem occurs intermittently during normal seat adjustment. Unknown if the issue has been reproduced or formally confirmed by a dealer or independent service center. The component should be available for inspection upon request. No warning lights or messages were observed prior to or during the occurrence of this issue.

The driver-side power sliding door latch, motor and cable system on my 2019 Honda Odyssey elite failed. Honda performed recall a88 (sliding door handle cable repair) in 2021. After this repair the door began intermittently failing to close fully and would close about 80% before the sensor triggered it to reopen. This continued until this week when the door suddenly stopped latching completely. The automatic door buttons no longer work and the door can only be moved manually. I believe my vehicle should also be included in recalls z33 and o36 addressing sliding door latch failures affecting similar 2019 Odyssey vehicles. The failed components are available for inspection upon request. This defect creates a serious passenger safety hazard. Because the door will not latch, it opens while driving. The automatic function does not work and the door can be moved manually but will not latch. This creates risk of passenger ejection, especially children, and the possibility of the door opening during a crash. The vehicle is unsafe to operate. Yes. The failure was reproduced and confirmed by a Honda dealership that inspected and diagnosed the sliding door failure. The vehicle was inspected by a Honda dealership and I was charged a diagnostic fee. Honda refused recall or goodwill coverage because my VIN is not included. I request the repair be performed free under recalls z33 and o36 and the diagnostic fee reimbursed. I am waiting for NHTSA inspection and request Honda be required to include my vehicle and repair it at no cost. Before total failure the door would close about 80% and automatically reopen. When it stopped working this week, the dashboard displayed a “left sliding door problem” warning and the vehicle produced continuous beeping while driving.

The sunroof/moon roof glass suddenly popped and exploded. No debris of any kind or any car was near me. My car was alone. The roof spontaneously made a “pop” sound and exploded. I’m lucky I wasn’t killed, injured, or in an accident. Glass that explodes and shatters can cause serious harm. There is obviously some sort of defect in Honda’s sunroof glass. Please investigate this thoroughly.

After a heavy rainstorm, the power tailgate motor stopped opening or closing the tailgate.
