|---|---|---|---|---|
| Jan 2026 | POWER TRAIN,ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL | Upon starting the vehicle, it failed to engage in reverse. Although the backup camera activated, the vehicle remained stationary. After multiple ignition cycles, the vehicle eventually engaged in reverse and then moved forward in Drive. However, shortly after, the vehicle experienced a sudden loss of power and entered "limp mode," restricting speed to approximately 15–20 mph regardless of throttle input. The engine revved excessively high without corresponding acceleration, and a severe burning/heat smell emanated from the transmission/engine compartment. This failure occurred without any prior warning; notably, no dashboard warning lights or "Check Engine" indicators illuminated to alert the driver of a mechanical or electronic fault. The sudden, un-signaled drop in speed on a public roadway created a significant safety hazard for following traffic and risked a rear-end collision. The vehicle was towed to a certified Honda dealership where the Transmission Control Module (TCM) was diagnosed as failed. The TCM is currently being replaced under the Honda Certified Pre-Owned (CPO) warranty. We do not know what else requires replacement and repairs. The dealership will not cover the replacement of the transmission fluid, or engine fluid, despite the fluid being subjected to extreme heat and potential damage during the failure and subsequent limp mode. | Crash: No Fire: No | Unknown |
| Jan 2026 | ELECTRICAL SYSTEM,EXTERIOR LIGHTING,ENGINE | Car would randomly die while I was driving, causing my children and I to be in severe danger in the middle of a busy road multiple times | Crash: No Fire: No | Unknown |
| Dec 2025 | ELECTRICAL SYSTEM,STRUCTURE | This is now the second time that we are having a rear hatch failure. with about 37,000 miles on this van, the control module shorted out due to water getting into it due to a bad seam (according to other Odyssey owners who are suing Honda for this). We could not get the hatch to open or close, so I paid the dealer to fix it. Honda did give us a check after the fact to cover some of the bill. Now, with less than 51,000 miles, it has happened again. The hatch will not open or close. In the event of an emergency, this is a major safety issue, to be potentially stuck inside the cabin. The hatch started going up and down randomly, and we could not control it. Now, it won't go up or down. This van is is a mess. Not only does it have this issues, but the rear back up camera still does not work, even though it was recalled...they would not honor their recall, and the brakes occasionally come on without cause, when going around a corner and there is oncoming traffic. It thinks that we are headed for a collision, and it's another safety problem here in the northeast. Honda needs to own up to their quality problems relative to these three safety issues. | Crash: No Fire: No | Unknown |
| Dec 2025 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | FEDERAL SAFETY RECALL 23V-431 FAILED AFTER FOUR REPAIR ATTEMPTS - MULTIPLE SAFETY SYSTEMS NOW NON-FUNCTIONAL My Honda was subject to Federal Safety Recall 23V-431 (MOST Communication Cable causing backup camera failure). After FOUR repair attempts, the original defect persists AND multiple additional safety-critical systems are now failing. REPAIR HISTORY: August 7, 2023 (30,749 miles) - Honda San Carlos performed recall repair 23V-431. Dealer claimed issue resolved. October 5, 2024 - Original backup camera/infotainment failure returned. I documented with photo evidence but problem was intermittent. September 29, 2025 (48,038 miles) - Returned to Honda San Carlos. Same backup camera failure. Dealer attempted repair. November 18, 2025 (48,928 miles) - Returned to Honda San Carlos. Problem persists. Dealer claimed repair complete. December 20, 2025 - Returned to Honda San Carlos. Original problem PLUS multiple NEW safety system failures now appearing: Backup camera (original recall issue) - STILL FAILING Adaptive Cruise Control - ERROR Collision Mitigation System - ERROR Lane Keep Assist System - ERROR Auto High Beam System - ERROR Front camera - ERROR DEALER RESPONSE: Honda San Carlos now claims new failures are "unrelated" to recall 23V-431 and proposes $2,900 for front camera replacement. I declined as all failing systems communicate via the MOST network that was subject to the original recall. SAFETY CONCERN: I now have a vehicle with MULTIPLE non-functional federally-mandated and safety-critical systems due to what appears to be the same MOST communication defect that recall 23V-431 was supposed to fix. The recall remedy has demonstrably failed and the problem is worsening. Honda's recall remedy is inadequate and has resulted in cascading safety system failures. Vehicle is unsafe to operate with non-functional collision mitigation, lane keep assist, and camera systems. | Crash: No Fire: No | Unknown |
| Dec 2025 | AIR BAGS | 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. | Crash: No Fire: No Injuries: 1 Medical attention | Unknown |
| Dec 2025 | ELECTRICAL SYSTEM,STRUCTURE,UNKNOWN OR OTHER | The auto slide door latch will not disengage. The rear passenger door cannot be opened electronically OR manually. | Crash: No Fire: No | Unknown |
| Dec 2025 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Multi-Purpose camera has failed according to Honda dealership. No safety features work in the car. You pay for the car to have these features and then they fail after only 3 years? Have been dealing with this issue for almost 2 years now. Honda wants $1,800 for the new camera. This is a safety issue that Honda should be responsible for fixing. No adaptive cruise control, no lane keeping assist, no auto headlights, no collision mitigation, no blind spot alarms. | Crash: No Fire: No | Unknown |
| Dec 2025 | LANE DEPARTURE | 2020 Honda Odyssey EX LKAS, Collision Avoidance, Auto High Beam etc. warning lights to cycle continuously. Had my Honda mechanic check problem and Camera Monocular, forward facing camera causing issues and requires replacement. This is only a 5 year old vehicle with 60,000 miles on it! Honda and many used auto parts want upwards of $850 for camera and then as much as $1500 to replace. This is a serious safety issue. None of this vehicles Safety assist items work without this camera. | Crash: No Fire: No | Unknown |
| Dec 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | In December, out of the blue suddenly had rotating list of warning on dash panel (Lane Keeping Assist problem, Collision mitigation system, departure mitigation system problem, auto high-beam problem, Adaptive cruise control problem) plus Brake Warning system light is on constantly and brake hold not working. At first this was intermittent but now on constantly when starting and driving car. Only 55k miles on my Odyssey. Dealer said he had 3 of these in the last three months. Said it was Multi Purpose front camera failure. Cost over $1500. Since huge safety issue putting not only my family but other cars/people at risk, we are paying to repair, however we just found hundreds of people complaining about this same issue. This should be a Honda Recall. We did nothing wrong to cause this safety issue and this part should NOT fail in 5 years. I don't have the final invoice yet but I can upload later if required | Crash: No Fire: No | Unknown |
| Dec 2025 | LANE DEPARTURE | The tailgate control module has been water damaged and needed to be replaced twice. My local Honda dealership was unable to correct the issue and stated that it is due to a water leak in the frame of the vehicle/tailgate. The dealership has identified the tailgate control module as the cause of the electrical issues causing the battery to die, and advanced safety features to malfunction. Warning lights came on for break system problem, lane departure mitigation system problem, and many other systems all caused by the tailgate control module being water damaged from a leak in the frame. | Crash: No Fire: No | Unknown |
| Dec 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The front camera that regulates the adaptive cruise control failed. Now it does not allow for any of the safety features to work. I’ve gone on multiple Honda forums and a lot of people have the same issue. | Crash: No Fire: No | Unknown |
| Dec 2025 | UNKNOWN OR OTHER | Summary of the Problem: The power tailgate motor on my 2020 Honda Odyssey has failed multiple times, causing the liftgate to stop midway, refuse to open, or abruptly close on its own. This failure creates a safety risk because the tailgate can unexpectedly drop or close on adults or children standing underneath it. Detailed Description: The tailgate motor on my 2020 Honda Odyssey has stopped working correctly on three different occasions. I have taken the vehicle to the Honda dealership repeatedly and have paid hundreds of dollars for repairs, yet the problem keeps returning. The tailgate will randomly stop while opening, won't fully lift, or will close unexpectedly and forcefully. This is especially dangerous when loading children or cargo, as the tailgate can fall without warning. After researching online, I found many other 2020 Odyssey owners reporting the same tailgate motor failure, indicating that this is a widespread issue rather than normal wear. The repeated failure suggests a potential design or safety defect. I am requesting that NHTSA investigate this recurring malfunction as a potential safety issue and determine whether a recall or corrective action is necessary. | Crash: No Fire: No | Unknown |
| Dec 2025 | ELECTRICAL SYSTEM | Dash has warning light showing "Power Tailgate Problem", and power tailgate will not function. The next day there was heavy rain, and the dash had a flickering warning showing the tailgate was open. This also caused the interior lights to flicker on and off as the tailgate open warning was flickering on and off. I returned the van to my home for fear that the tailgate would open automatically while driving down the road. I had the tailgate control module replaced on February 27, 2025 for this same issue, which was due to a tailgate seal leaking water onto the tailgate control module that shorted the module. This is now the second time within less than one year this same module has shorted out. This is a known issue with a class action lawsuit already filed against Honda that should result in a recall. The potential danger of the tailgate opening while driving makes this minivan not usable to transport my kids for fear of their safety. | Crash: No Fire: No | Unknown |
| Dec 2025 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | After researching I find it to be a sensor in the windshield is a common problem | Crash: No Fire: No | Unknown |
| Nov 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The forward facing camera failed on my 2020 Odyssey with only 90,000 miles. Because of this failure, I am loosing all my forward facing safety features. This seems to be a common issue across many Honda vehicles and most users report being told the issue is being caused by overheating. Since users are being told this is a cause and effect issue, the manufacturer should address this at their expense. I first noticed this issue in mid September 2025. | Crash: No Fire: No | Unknown |
| Nov 2025 | FUEL/PROPULSION SYSTEM | When pressing the accelerator, there is an extremely loud and abnormal noise coming from the fuel pump. The noise is so severe that it raises safety concerns while driving. The issue appears similar to fuel-pump–related problems reported in other recalled Honda vehicles. | Crash: No Fire: No | Unknown |
| Nov 2025 | ENGINE | My wife started hearing a knocking sound while driving, coming from under the hood. I opened the hood while the engine was idling and could tell the sound was coming from inside the engine. Checked the oil level and it was in the operating range and looked clean. I had just changed the oil and filter 08/2025. After that we immediately drove it to the Honda dealer where we purchased the vehicle and the service manager heard the noise, checked for recalls, but could only find the recall for the 2019 Honda Odyssey [XXX] The service manager called in one of his mechanics to listen to the noise in the service manager bay and he said, "Sounds like a bad rod bearing". They then took the vehicle to inspect it further in the mechanic's garage, but as they were pulling it into the bay the engine complete seized up. The vehicle only has 68k miles on it, but now its beyond the warranty period. I was also told by the dealer when I purchased it, that it and the 2019 are identical, so why was the recall issued for the 2019 Odyssey, but not the 2020 model? I'm reading lots of similar reports of this same exact issue with the 2020 model from Honda forums and on youtube posts. This engine problem is clearly larger than the initial recall that was issued in 2024. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Nov 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The camera controlling many systems regarding safety failed and caused numerous warning lights to come on. Complete camera replacement was necessary. | Crash: No Fire: No | Unknown |
| Nov 2025 | STRUCTURE | Driver side rear sliding door will not open even when the automatic release button is disengaged. Some could be trapped in an emergency or I am worried that if it opens I will not be able to get it closed. | Crash: No Fire: No | Unknown |
| Nov 2025 | ENGINE | Connecting rod bearing failure at 105,000 miles, even with full recommended and documented service history. | Crash: No Fire: No | Unknown |
| Oct 2025 | AIR BAGS | Side airbags deployed while driving down road at about 35 mph hitting a minor bump in road. Air bags deployment while the car is in motion during safe driving conditions is a distraction to the driver and harms the passengers who are in the vehicle who if the airbags did not deploy would have remained safe since no collision was experienced. Took vehicle to Honda dealership- who stated airbags worked as intended and we needed to file a collision claim with insurance- despite no collision taking place and no other damage to the car i.e. no bent rim or flat tire/tire damage. Just saw article stating our scenario was not unique to our make/model of van. | Crash: No Fire: No | Unknown |
| Oct 2025 | FORWARD COLLISION AVOIDANCE | Several warnings lights appeared on the dash at the same time regarding the accident safety features including: Adaptive cruise control, automatic emergency braking, forward collision warning, lane departure warning and lane keep assistance. None are currently working. The warning randomly appeared. It's associated with the camera behind the windshield and the radar detection behind the front emblem. Problem confirmed by dealer. Components have not been evaluated by anyone. | Crash: No Fire: No | Unknown |
| Oct 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | All warning lights came on for Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, and Lane Keeping Assistance.Based on my research, it seems the forward facing camera has failed. The vehicle only has 37,000 miles on it and it is only 5 years old. | Crash: No Fire: No | Unknown |
| Oct 2025 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Make: Honda Odyssey 2020 Mileage at Failure: ~40,000 miles Incident Description What component or system failed or malfunctioned, and is it available for inspection upon request? The front sensing camera system failed, which controls multiple driver-assistance features, including Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Lane Departure Mitigation, and Collision Mitigation Braking System. When the issue occurred, all related dashboard warning lights illuminated simultaneously. The vehicle’s front camera module is still installed and can be made available for inspection upon request. How was your safety or the safety of others put at risk? When the camera malfunctioned, all driver-assistance and collision-avoidance systems were disabled without warning. This created a serious safety concern because the vehicle unexpectedly lost its lane-keeping, adaptive cruise control, and collision mitigation capabilities while in motion. It increased the risk of a crash, especially during highway driving or when relying on these systems for lane and speed control. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The Honda dealership confirmed the issue after diagnostic testing and stated that the front camera module had failed and must be replaced. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by the authorized Honda dealership. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The dashboard displayed multiple warning messages, including: ACC, LKAS, Collision Mitigation, Lane Departure Mitigation These warnings appeared suddenly at approximately 40,000 miles and have persisted since. The dealer quoted $2500 Also I found numerous reports from other Honda owners experiencing the same camera-system failure at low millages. | Crash: No Fire: No | Unknown |
| Oct 2025 | ENGINE | I was driving with family to a family trip up to the mountains to enjoy the snow when at a rest area I noticed the odyssey just had a slight delay to turning on before continuing the trip. No lights no signs of anything going wrong. As we continued our trip back onto the freeway on a curvy road and night time the odyssey didn’t want to shift gears wouldn’t speed up for freeway traffic. Immediately started pulling over. The odyssey would make like jerking movements decided to call the tow truck and it quickly escalated to draining the battery. After being at the tow facility for one night it completely didn’t want to even turn on next day. Put a new battery and still drains the battery. I took it to Honda service to run a diagnostic and they come back saying the engine is seized. No lights no signs didn’t see this coming with only 87,000 miles. With a black screen displaying electrical issue at times. | Crash: No Fire: No | Unknown |
