Warning Problems of Honda Odyssey - part 1

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.

I randomly received a series of 6 warning messages when starting the car on 9/3/26. They were all warnings related to the automatic safety features such as lane departure, collision detection, auto bright lights, etc. I took it to the dealer on 9/4/26 & they diagnosed an internal failure with a multi-purpose camera embedded in the rearview mirror. The dealer ordered a new part, installed and reprogrammed and recalibrated the camera. This vehicle has been owned only by me, is kept in a garage away from weather exposure, there is no reason for this part to fail on a 6 year old car with a hefty cost to the consumer.

Multipurpose camera on the Honda safety sensing system has failed. There are no warnings for blind spots or lane assists. My daughter will be driving this car. Confirmed by a service center with a diagnostic completed. No warning signs prior to failure. It failed on 8/30/2026.

Safety complaint – 2019 Honda Odyssey elite front camera failure I own a 2019 Honda Odyssey elite with approximately 60,000 miles. The front windshield camera used by the Honda sensing system failed. When the camera failed, the vehicle displayed approximately 11 warning messages/errors involving multiple safety-related systems, including the brake system, vsa, eps, electric parking brake, brake hold, hill start assist, and Honda sensing features such as acc, lkas, and cmbs. This was concerning because one camera failure caused multiple safety systems to become unavailable or display warning messages. The vehicle’s driver-assistance and safety functions were significantly affected. I took the vehicle to a Honda dealer, and the dealer diagnosed the front Honda sensing camera as defective and replaced it. The total cost was approximately $2,600, including the camera, parts, labor, and calibration. I believe this is an unusually expensive failure for a critical safety component, especially on a vehicle with only approximately 60,000 miles. The front camera is not a normal wear item and is essential to several Honda safety and driver-assistance systems. I am also concerned that similar Honda owners have reported failures involving Honda sensing cameras. I would like NHTSA to investigate whether there is a recurring or widespread defect involving the front Honda sensing camera on Honda Odyssey vehicles, particularly model years 2018–2020. I respectfully request that NHTSA review complaints and repair records related to this issue and determine whether further investigation or a safety recall is warranted. I am submitting this complaint because I believe owners should not have to pay approximately $2,600 to repair a potentially recurring defect in a critical safety component.

In August 202, the multipurpose monocular camera failed. My car is a 2019 Honda Odyssey exl. I was not involved in any accident or incident that would have caused this to fail. When this camera fails 5 warning codes popup: collision mitigation braking system failure , lane keeping assistance system failure, adaptive cruise control failure, road departure mitigation and auto-high beams stop working. The dealer priced the repair at ~$2,100. Many reports are coming up with this failure and it seems driven by overheating of the camera module, a filed camera component, or other unknown reasons.

This vehicle will randomly turn these features on and instead of keeping you in your lane pull you off the road, I have had to pull over to turn the vehicle off to get it to turn off.

The windshield-mounted front monocular camera (Honda sensing unit) overheated and failed/burnt out. This failure completely disabled the forward collision warning, automatic emergency braking, lane departure warning, lane keeping assist, and adaptive cruise control systems, triggering multiple safety system warning lights on the dashboard.

Front camera failure shut off multiple safety features. Confirmed by the dealership service department. Safety features shut off adaptive cruise control, lane keeping assist, collision mitigation system, road departure mitigation system and blind spot info system. Driving this car under 43000 miles with multiple safety features off with messages flashing is stressful, distracting, uncomfortable and unsafe especially this car is mainly used for children. The worse part is that the dealership service department can not fix the problems because the part is back ordered. We have to continue to use this car in this unsafe condition.

Front camera failure causing all system errors to not work to include lane keeping assist, adaptive cruise control, lane departure warning, auto high beam.

The contact owns a 2016 Honda Odyssey. The contact stated that while driving 45 mph, the forward collision warning, lane departure warning, engine, and vsa warning lights were illuminated. While at the stoplight, the vehicle started jerking and sputtering. The contact stated that the failure was related to technical service bulletins: 25-060 and 25-061. The vehicle was taken to the local dealer, where it was diagnosed and determined that there was a misfire coming from the engine. The contact stated that there was oil in the cylinder head. The manufacturer was contacted and opened a case. The manufacturer confirmed that the warranty had expired months earlier, and the case was closed. The failure mileage was approximately 162,600.

I am reporting a safety-related defect involving my **2019 Honda Odyssey ex-l** (VIN: **5fnrl6h76kb029137**) with approximately *,156 miles**. **"brake system"** warning message appears first. Within seconds, additional warnings appear one at a time for **adaptive cruise control (acc), lane keeping assist system (lkas), collision mitigation braking system (cmbs), road departure mitigation (rdm), and automatic high beam**. All of these safety systems become unavailable. The vehicle continues to drive and brake normally, and the speedometer functions correctly. The blind spot information system and rear parking sensors continue to operate normally. A diagnostic scan performed by a vip Honda mechanic identified **diagnostic trouble code u3000-* stored in the **front multipurpose camera module**, indicating an internal camera module fault. The battery and alternator have been tested and are operating correctly. The vehicle has its **original windshield**, has **never been involved in a collision**, and there are * signs of water intrusion** around the front camera assembly. This failure occurred suddenly during normal driving without any known external cause. The failure disables multiple collision avoidance and driver assistance systems that are intended to help prevent crashes. Because these safety systems become unavailable during normal vehicle operation, I believe this represents a potential safety defect that should be investigated. I have notified Honda of this issue and opened **american Honda customer relations case #165-16502**. Honda is currently reviewing the matter for possible goodwill assistance. I respectfully request that NHTSA investigate whether similar front camera module failures (dtc u3000-49) are occurring in other 2019 Honda Odyssey vehicles equipped with Honda sensing.

U3000-49, multipurpose camera unit internal failure, no impact, no glass work.

The front camera is intermittent and sometimes it works but other times I get 5 error messages when I start my car: adaptive cruise control problem, lane keeping assist problem, collision mitigation system problem, road departure mitigation system problem, auto high-beam problem. In reviewing online, it seems like this is a very common problem with all of these models. Since the repair rate is over $1000 you’re going to have a lot of vehicles on the road without the safety features working. Since it’s intermittent, there’s something with the connection between the camera and the computer. If the camera were broken, it wouldn’t work at all. Any people say they can bang on the camera but that doesn’t seem like a safe fix. I believe this needs to be investigated.

Multipurpose camera failure causing multiple displays on dashboard.

I have 2019 Honda Odyssey and my front windshield camera shows multiple lights also nothing works there are shows 11 working lights also I go dealer and they toll me you have to replace your windshield camera and it cost $2200 and not only me there are so many people facing that same problem plz give a recall for Honda Odyssey year 2018 2019 & 2020.

After the vehicle is off, and after the Smart key fob is removed from the vehicle, the dashboard will flicker, the alarm sometimes goes off and the headlights turn on draining the battery and leading to me having to jump the car to get it started. This makes the car undependable as it could happen after driving somewhere and leave myself or my wife stranded. I have taken this in to the Honda dealership but they noted that it did not occur when they were servicing the vehicle and they weren't sure what the issue could be. Many times the check engine light, fcw and ldw lights will come on and then reset after the car has been driven.

On 5/28/26, I went to get my van checked at a repair shop through my healthcar warranty and I was told that I needed a system update on my brake system/adas/lkas/acc systems. All the lights beeped and were lighting up on my dash. It would go on and off from time to time, usually when it was more hot out. They told me to take to dealership and they need to do a system update and should fix no additional charge. I took it to the Honda dealership service department on 7/6/26 and was told it is the multipurpose camera has an internal failure and it would cost me $2,443. 00 to repair it, plus I had to pay them a diagnostic fee. I have researched and been told by other repairs shops that this problem has been occurring often and it seems due to heat is the reason this happens.

My van is suddenly giving me warnings that include collision mitigation, road departure mitigation, adaptive cruise control, lane-keep assist, brake hold system, and traffic sign recognition. My safety is at risk if the front camera system is not working/faulty. I was unaware of the problem and had my cruise control on when it just went off and there were warnings popping up on dashboard. There was a class action lawsuit filed against Honda on 7/2/26 in CA for certain Honda vehicles. I have had my van put on a computer that has given us the error code and is a front camera failure. The issue first appeared on 7/2/26. It will suddenly start flashing warnings when I’m driving. It will also flash warnings right after I start the vehicle.

I have received warning lights associated with safety features controlled by front facing windshield camera indicating that the acc, auto braking, lane departure and front collision avoidance features were not working. This has happened once before just over a year ago and I was told by the dealer that the camera needed to be replaced. I did so, at a cost of over $2k. All features worked again after the costly replacement, until last month, just outside of the one year warranty on the new camera. This is clearly an issue with either the camera or a connected electrical issue. This van also has a breach in the body wields at the rear lift gate opening in which water is able to seep into the interior of the body behind the interior rear side panels. During heavy rains the carpet on the right side trunk area is wet and can be tracked to coming from behind the right rear interior molding. I have not yet removed the molding so I am unsure if any electrical components connected to the front camera and associated safety features are located there and might be causing these safety feature issues. At a minimum, both of these issues, the camera constantly quitting, as well as the breach in the body allowing moisture intrusion, should warrant a forced recall for Honda to address and correct each item.

Failure in the front multipurpose camera. None of the drivers assisted safety features work now. These include: adaptive cruise control, emergency braking, lane keep assistance, lame departure warming, and others.

Camera malfunctions with low mileage.

Component affected: forward-facing multipurpose camera / advanced driver assistance systems (adas)description of safety hazard: while operating my 2018 Honda Odyssey on a public road, the forward-facing multipurpose camera suffered a sudden, unprovoked internal hardware failure. This failure instantly triggered a cascade of severe dashboard warning lights and error messages. The camera failure completely disabled multiple critical active safety systems simultaneously, including: collision mitigation braking system (cmbs)lane keeping assist system (lkas)road departure mitigation system (rdm)adaptive cruise control (acc)auto high-beamssafety consequence: the sudden loss of these active safety technologies dramatically increases the risk of a high-speed collision, as the vehicle can no longer autonomously detect obstacles, mitigate frontal impacts, or assist with lane keeping. Crucially, the total failure of adaptive cruise control left the vehicle with no standard cruise control functionality whatsoever during highway driving, creating an unexpected distraction and safety hazard. The dealership confirmed a failed front camera module and quoted $2100 to replace and recalibrate the unit. This is a systemic hardware defect affecting 2018 Honda Odysseys that requires a formal safety recall.

The camera located behind the rearview mirror is faulty. In hot weather locations (like mine in florida) it stops working. And that means all electronically assisted driving systems lkas (like cruise control, auto high beam, lane departure, auto distance monitor/collision warning, etc. ) malfunction, giving flashing messages about all non-working features. This is due to cmos image sensor degradation caused by heat exposure. Many people have expressed concerns about this on different Honda forums online. I took it to a Honda dealer and after paying a fee for diagnosis, the service manager said that when the temperature outside gets hot, they get a lot of this kind of service request. They want over $2,300 to replace the camera. They were actually puzzled why Honda does not recall this item. Honda needs to address this since it is actually safety related and indeed a faulty item. There should be no reason for people to pay this outrageous price for something that is clearly a manufacturing problem.

Sensor failed, causing many safety systems to fail - front collision warning, lane keeping assistance, lane departure warning, adaptive cruise control, etc.

The forward facing adas camera has been reporting u0104 error. This resulted in many advanced safety features failing, including adaptive cruise control, automatic emergency braking, forward collision warning, and lane departure warnings. The problem was confirmed and repaired by a independent service center. The problem first appeared on June of 2026.

There’s more thant went wrong but won’t let me add them. My front camera seems to be the issue but many are having the same exact issue. I just bought it not too long ago. Worked fine until this recall came out.

This is a report on a design flaw- not a failed component- in the 2026 Honda Odyssey's "Smart" computer automated safety features, including automatic braking, lane departure, and forward collision warning systems. There have been two types of incidents. These incidents have been repeated on this vehicle dozens of times in our first year of ownership. These incidents are potentially very dangerous because they involve erroneous automatic braking at interstate highway speeds. Unexpected erroneous braking at interstate speeds is a good way to cause a rear-end collision or loss of control. 1. Automatic emergency braking due to erroneous lane departure detection. On interstates in arizona at highway speeds of 65 mph, the vehicle's lane departure detection system throws erroneous warnings when it sees non-lane markings on the roadway, such as tar sealant strips or seams between pavement sections. This has resulted more than once in the vehicle erroneously applying emergency automated braking to slow the vehicle. This happens even when lane assist and adaptive cruise control are turned off by the driver. 2. Erroneous automated braking while overtaking another vehicle. On interstates in arizona at highway speeds of 65 mph, while passing in the left lane a vehicle that is moving much slower in the right lane (e. G. Semi truck climbing a hill at 40 mph), while using adaptive cruise control, automated braking is applied erroneously when there is no risk of a forward collision. The automated braking tends to kick in far earlier than a human driver would brake, and when there is no vehicle in the lane ahead, so it is unexpected and dangerous. This only happens while adaptive cruise control is activated by the driver.

Cmbs error again now having lane assist error.

The vehicle is showing persistent electrical and communication fault codes involving the ecm, abs, and eps systems, including p16e2, p16e5, p16e7, p16e8, u0401, and u0416. These codes return immediately, which suggests an active fault rather than a temporary low-voltage condition. The issue appears to involve the battery sensor and/or the related communication network between control modules. Because the faults involve abs and eps communication, the concern is that braking-related or steering-assist systems may not be receiving correct data. This creates a potential safety risk because the vehicle may experience intermittent or unreliable control-module communication, which could affect steering assist, braking-related warnings, or overall drivability. The warning lights and diagnostic codes first appeared before the vehicle was put back into normal use and have continued to remain present. The problem has been reproducible because the codes reappear right away after being cleared. No dealer or manufacturer diagnosis has been confirmed yet, so the exact root cause remains unresolved.

While driving the vehicle under normal conditions, multiple advanced driver assistance and safety systems suddenly became unavailable without warning. The systems affected include automatic emergency braking, forward collision warning, lane keeping assistance, and related safety features that rely on the forward-facing camera. The failures occurred at the same time and were indicated by warning messages displayed on the instrument panel. The vehicle was inspected by an authorized dealer, who confirmed a diagnostic trouble code indicating an internal electronic failure of the forward multipurpose camera. The failed component is installed behind the windshield and is available for inspection upon request. The dealer stated that no accident, physical damage, misuse, or external cause was identified. After the camera failure was identified, the vehicle also briefly displayed a transmission system warning message that later cleared on its own. In addition, the center display screen has shown unstable behavior while driving, including unexpected resets and flashing back to the navigation screen. The sudden loss of collision mitigation, lane assistance, and warning systems reduces the vehicle’s ability to assist in avoiding crashes, particularly in emergency situations, and increases safety risk to the driver, passengers, and others on the road.

While driving on highway, multiple warnings displayed at the same time as adaptive cruise control stopped, lane keep assistance stopped and collision mitigation system stopped abruptly without warning. Independent service check confirmed the problem. No inspection performed. Vehicle has never been in a collision during ownership.

Front camera is bad or faulty, triggering all adaptive cruise control, lane keep assist, auto high beam etc errors on dashboard, rendering the car not able to start or die in the middle of the road/traffic when the engine goes into idle mode while stopping at red lights. My odessey has over 111k miles when these issues start showing, but lots of people report experiencing same issue with even with their newer odessey. It doesn’t feel right why Honda installed cheap cameras especially when it plays a crucial role involves safety of the car and the driver.

I believe the forward facing camera is having electrical issues which is causing the vehicle not to engage lane departure, traction control, lane keeping assistance, emergency braking, adaptive cruise control, ac intermittently blowing warm and cold. There are four or five lights on the dash about this.

System failure for all of the safety-related assistants. Works intermittently, but mostly indicates failure.

Getting error code for safety sinsing. Lane keep assist, collision mitigation system and now transmission system. Forward facing camera is cause of issue.
