| Jun 2025 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | The problem first appeared in May 2025 when multiple system failure lights illuminated simultaneously. After confirming the battery and alternator were in good condition, I took the van to Honda of Cleveland (2701 S Lee Hwy, Cleveland, TN 37311) for a diagnosis. Their service department confirmed that the ADAS Front Camera (36160-THR-A91) had failed, which disabled the following safety systems: Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, and Lane Keeping Assistance. I asked if this is a wear component (expected to need replacement over time) and was informed that it is not. The quoted cost to replace the camera and calibrate was approximately $1,400. | Crash: No Fire: No | Unknown |
| Jun 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Multipurpose front windshield camera stops working and many safety features are affected by this camera. Lane departure warning is not working, lane keeping assistance not working, blind spot warning not working, brake system warnings. The vehicle has been inspected by the dealership and they confirm that the cause of all this problems is the Multipurpose front windshield camera. There was no warnings at all when this happens. | Crash: No Fire: No | Unknown |
| Jun 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Multiple warning lights: 1. ACC- adaptive cruise control 2. LKAS- lane keeping assist problem 3. Collision Mitigation System Problem 4. Road Departure Mitigation System Problem 5. Auto high beam Problem Safety issues: With almost all of these not working the risk of avoiding a possible accident is greatly increased. An independent service center read errors for the CAN. No prior warnings, they just came up. I have replaced the battery and the issues were not resolved. An inspection is possible. | Crash: No Fire: No | Unknown |
| Jun 2025 | ELECTRICAL SYSTEM | The start/stop system engaging at a red light on a busy highway shutting the engine off. When the light turned green and my foot was released from the brake the vehicle would not restart. The vehicle would not go into neutral so i was stuck in the lane of a major highway. This happened twice before and Honda said they needed to reprogram the system. They did and now it has happened again leaving me and my family in a very dangerous situation. | Crash: No Fire: No | Unknown |
| Jun 2025 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | The front camera/sensor broke and is not covered under Honda’s warranty. This affects the adaptive cruise control, lane keeping assist, collision mitigation system, road departed mitigation, and auto high-beam. | Crash: No Fire: No | Unknown |
| Jun 2025 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | Recently, my 2020 Honda Odyssey required a new battery replacement. Shortly after the battery was replaced, the front camera system failed unexpectedly. This failure has caused a complete loss of all safety features dependent on the front camera, including but not limited to: Lane Keep Assist System (LKAS) Collision Mitigation Braking System (CMBS) Adaptive Cruise Control (ACC) Road Departure Mitigation System (RDM) A diagnostic assessment revealed that the front camera system needs replacement with an estimated cost of $1,200. This issue arose without any previous physical damage to the camera or windshield and appears to be electronic or firmware related. According to Honda, this happens frequently when a battery is replaced. Context of Vehicle History: This vehicle has already been subject to 11+ recalls, which have affected various major systems and components. The accumulation of defects and the continuing need for critical system repairs is deeply concerning, particularly for a relatively recent model known for its family-oriented safety features. Owner’s Statement: Given the number of recalls and now a costly camera system failure that directly affects key safety functions, I find this situation unacceptable for a vehicle of this age and mileage (72,000). The loss of these features significantly compromises driver and passenger safety. I believe this issue may be part of a broader reliability concern and request that Honda (or the responsible service entity) address this matter urgently and consider full or partial financial assistance for the repair. | Crash: No Fire: No | Unknown |
| Jun 2025 | ELECTRICAL SYSTEM,LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | Our Odyssey has had mounting concerns w/electrical system. These are safety issues. 10/20. Work done related to electrical system-rear camera having issues. Left/rt rear door wires were replaced due to recall. Software update completed. Gage control module software updated-know issue.10/23: rear windshield wiper not functioning-electrical issue & pump malfunctioned. Idol stop was not properly working. The car would stall out at stoplights as lifting foot off the brake & attempting to accelerate. Battery was replaced at this time & the vehicle was only 3 years old-we were charged. Issues with our car are electrical related & are seeing many others with similar issues. 8/24-11/24: key fob batteries died. After batteries were changed, issues with the power windows began immediately. Windows would not going/up or down all the way and were sticking. Soon after they stopped working all together. Auto locks wouldn’t work & the gas tank latch had to manually open to fill the gas tank. Finally took the car in for diagnosis. Said the motor in the door was broken & needed to be replaced. We were not convinced that this was the real issue b/c the problem began immediately after the fob battery issue. Instead of new parts, the dealer glued pieces together & gave us a discounted price. This was & is a real safety concern especially knowing windows were altogether not functioning & we don't believe that it was properly addressed. 2/25: After snow/icy weather front passenger side windshield wiper dispenser/sprayer wasn’t working. Upon checking, discovered it had become dislodged. Adjusted the piece & reattached this piece into place. As soon as car was turned on ,right after reinserting the piece into place warning lights came on-all brake/lane mitigation lights. After diagnosis, said it was an issue with camera at windshield & the camera needed to be replaced. Odyssey groups state electrical issue are know and many w/2020 Odysseys. 5/25 Issues are beginning again with idol stop. | Crash: No Fire: No | Unknown |
| May 2025 | UNKNOWN OR OTHER | Rear tailgate doesn't open with keyfob or with switch on the back door. it had to be pulled hard to open in manually and pushed hard manually to close it. There are so many incidents reported on line for the same. The fix seems be a control board (Which gets bad due to water getting in the compartment (or on the board). We have talked to Honda - as per them there is no active recall on this. | Crash: No Fire: No | Unknown |
| May 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Starting at 50,000, I began receiving six different warning signs every time I turn on my car: (1) collision mitigation problem, (2) auto high beam warning, (3) lane keeping assist problem, (4) road departure mitigation problem, (5) adaptive cruise control problem, and (6) brake system light stays on. Online forums show this is a pervasive problem with 2020-2021 Odysseys at around 50,000 miles. Took it dealer for diagnostic, paid $229, and told me it would cost $2,000+ to fix. | Crash: No Fire: No | Unknown |

| May 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The camera is faulty and I've brought it in once early on and the dealer said a wire needed to be tightened. It happened again and they said no such loose wire this time. The code says camera needs to be replaced. I don't even have 100k miles on this car and it's going bad.

| May 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Turned on the car. It was parked for 1 day after the last driving event with no issues. Today was 15 degrees hotter than yesterday. The following errors popped up on the dashboard: Adaptive cruise control problem Collision mitigation system problem Lane keeping assist problem Road departure mitigation system problem Auto high beam problem All of the advanced safety features which utilize the front camera and sensors are deactivated. Car was turned off and restarted multiple times, windshield cleaned, and car cooled down, but the warnings remain each time. This specific issue has happened 5 times over the past year.

| May 2025 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | Subject: Urgent Vehicle Safety Concern – Sudden Malfunction and Safety Risk On [XXX], at approximately [XXX, I experienced a traumatic incident when my vehicle unexpectedly malfunctioned while I was driving home. After making a left turn on a green signal from [XXX] toward the Community, the car suddenly stalled. By God's grace, I managed to cross Woodbridge Avenue before stopping, avoiding a major traffic obstruction. However, it came to a complete stop in the middle of the street, creating a hazardous situation. After a brief pause, the car moved approximately 10 yards before stopping again, becoming completely immobile in the middle of a public road. Attempts to jump-start the battery failed. All warning lights turned on, but the engine would not start. The vehicle could not be restarted or moved under its own power. 911 was called, and police responded promptly to the scene. With the assistance of my wife, police officers, and local neighbors, a tow company was called to remove the vehicle from the roadway. It was then towed and parked in a nearby lot. This incident was highly traumatic and posed a serious threat to my safety, my family's safety, and the safety of the public. Diagnostics and expert assessments indicate the issue may be related to a manufacturer defect, which is deeply concerning given that this is a new vehicle. At this time, the vehicle is no longer drivable. I am seeking urgent assistance to resolve this matter with the manufacturer and to ensure that other consumers are not exposed to similar risks.

| May 2025 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | The front camera has failed for apparently no reason at all. There has been no crash, no damage on our end. We turned the car on and all of the safety warnings came on. The dealership has inspected it and said the code is for the camera failing. Many warning lights appear on the dash due to none of the safety features working without the front camera. This has caused all of the adaptive safety features to fail. There have been no recalls yet, despite the recalls for the rear camera, and many other odyssey owners having the same issue with the front camera. We have reported it to honda and were told that it has been reported by others, but not enough times to issue a recall. It is expensive to fix and poses a serious danger to leave due to none of the safety features working. This is a manufacturing defect that honda is not taking seriously. | Crash: No Fire: No | Unknown |

| Apr 2025 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | Front facing camera went out on a 2020 model. Several warning lights appear related to lane assist, front collision warnings, and automatic emergency braking. These safety features are important, and Honda should issue a recall. The camera is around $800 to replace, plus another $800-$1000 to install and calibrate. Car is only 5 years old, and there have been other camera/electrical related problems, and many recalls. Please hold Honda accountable to fix their declining reliability issues. | Crash: No Fire: No | Unknown |
| Apr 2025 | ELECTRICAL SYSTEM,LANE DEPARTURE | There is some electrical or sensor issue with the 2020 Honda Odyssey EX-Ls. All my dashboard lights turn on, then I take it to the dealership to tell me they just had to do a system update. This is the 3rd time it has happened. This issue needs to be investigated. Honda is robbing me and many other owners of this issue. | Crash: No Fire: No | Unknown |
| Apr 2025 | ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | We have 2020 Honda Odyssey with 4500 miles and multi purpose camera quit working and Honda service center ran a scan and confirmed malfunction of camera and replacement costed over $1600. Internet tells me that many other similar vehicle have similar issue. It should be a recall and fixed free. | Crash: No Fire: No | Unknown |
| Apr 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | 1) Infotainment system crackles, pops, and shuts off frequently. Will not come on sometimes until 5 minutes into the drive, meaning we cannot use our rearview backup camera. This was recalled in other models but not our specific VIN. 2) “Shutter grill problem; power reduced” comes on randomly even when just idling. 3) Sliding doors will bounce shut or not open all of a sudden! Both doors affected similarly. Turning off the power doors does not solve the issue, so we lose access to one side. There was a recall on sliding doors for other models but not our VIN. We are taking it into the dealer to investigate but this is a safety issue. | Crash: No Fire: No | Unknown |
| Apr 2025 | UNKNOWN OR OTHER | Sunroof exploded while driving on the highway. | Crash: No Fire: No | Unknown |
| Apr 2025 | ELECTRICAL SYSTEM,ENGINE | Auto Idle Stop (AIS) system. had many of the other same symptoms that people reported. our car would go into idle mode and then it would not restart. I would have to turn the car off I tried to do various things just to get it started again. this happened one time was the exited the highway and also happened coming out of a car wash location. I took it to Honda and they said because of the idle stop functionality the starter went bad and they had to replace that. I was compensated some money from Honda but I believe I was only done so because they knew something was wrong and I really believe there should be a recall for this. it is completely unsafe and very scary when it happens especially in the middle of traffic. our starter was replaced because of this issue on November 5th 2024, but the symptoms had been going on for that whole calendar year prior | Crash: No Fire: No | Unknown |
| Apr 2025 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | The idle start stop feature constantly doesn’t work. When stopped at a light or stop sign the engine will turn off and when I release the break it is supposed to reengage the engine. Instead it stalls out causing me to have to put the car in park and restart the car. There have been several incidents where this is during rush hour traffic causing traffic jams. Sometimes I have to wait a few minutes before it will actually turn over. The car is 5 years old and I have had the replace the battery twice and I have been told that this feature puts a lot of pressure on the battery. Never can the dealership recreate the issue. | Crash: No Fire: No | Unknown |
