Warnings problems of the 2019 Honda Odyssey - part 1

?the multipurpose windshield camera module in my 2019 Honda Odyssey experiences an internal electronic/power failure (diagnostic trouble code u3000-49) while driving. This failure triggers a cascade of warning lights across the dashboard, instantly and without warning disabling the entire Honda sensing driver-assist suite—including collision mitigation braking (cmbs), lane keeping assist (lkas), road departure mitigation (rdm), adaptive cruise control (acc), and auto high beams.

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.

2019 Honda Odyssey ex : sensing camera located behind front windshield failed and stopped working and giving bunch of error messages. Cruise control and other saftey features operated with help of this camera stopped working. The part number is 36160-thr-a11-m1.

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.

Error with the front camera system without damage to the instrument.

With a 103,000 on the dash, engine experienced signs on slowing, check engine, abs, adaptive cruise, and steering faults amongst others . No lights prior to the bearing failing. The engine experienced rod bearing failure and left use stranded on the side of the highway. All maintenance was performed at dealership, towed back to dealership where upon inspection rod bearing completely fell apart. Vehicle is still at dealership where a 14,000 dollar engine was quoted.

Multipurpose camera failure causing multiple displays on dashboard.

I believe it is the windshield monocular multipurpose lkas acc camera. This sensor has malfunctioned for the past two moths and I've tried everything to fix it short of replacing it, which is ridiculously expensive. This is such a common problem on this make/year of vehicle. My car only has 75,000 miles on it.

The vehicle’s front camera/Honda sensing system has failed, causing multiple safety features to become unavailable simultaneously, including forward collision warning, collision mitigation braking, lane departure warning, lane keeping assist, adaptive cruise control and related systems. The failure produces multiple warning messages and disables safety systems that the vehicle was equipped and marketed with. This is a recurring issue reported by other Honda owners and is currently the subject of a proposed class action lawsuit, jones et al. V. American Honda motor CO. , inc. , case no. [xxx]. The lawsuit alleges a defective front camera system affecting 2018–2025 Honda vehicles, including the Odyssey. I believe this constitutes a safety defect because the failure can occur unexpectedly and simultaneously disables multiple driver-assistance and collision-avoidance safety systems. I am requesting that NHTSA investigate this issue and require Honda to issue a safety recall and provide a free repair. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

When those error codes appear, those safety features become unavailable during driving. These error usually come up when I just start the car.

On interstate 65 4/4/2026 during light traffic, after a rain storm, however with no rain currently occuring, our vehicle experienced an event where the collision avoidance system dropped out speed from 70 miles an hour to 35, nearly causing a rear end clission with a vehicle behind us. The dashboard made no indication of any occurance, and the breaking seemed to occur with no indicator of there being anyting in front of us at the time of the incident. This has occured before however after rainstorms, and while attempting to make left hand turns. This however was the first incident in which it clearly caused a near miss collision event.

The car has started giving warnings every time I turn it on (as of 6 months ago): adaptive cruise control problem, collision mitigation system problem, auto high beam problem, lane keeping assist problem. It seems there must be a fault in the windshield camera that renders all these safety features useless. The repair shop stated that windshield camera isn’t working and is a $2k or more to repair. I am now driving a minivan that doesn’t have many important safety features and this is very dangerous.

The front camera behind the rear view mirror comes up with code and the cruise control will not work and the lane departure system and the forward collision system and adaptive cruise control. The front camera issue can only be repaired by replacing the camera between 800 and 1500 cost to purchase the camera plus a 5 to $700 adas aiming at the dealership and I don't feel that that's correct being that almost every single Honda Odyssey I've touched in my repair shop from 2018 till current has this code coming up. Sometimes I can put a scan tool on the vehicle and clear out the code and do a dynamic aim and the vehicle will correct itself but it will come back relatively quickly and sometimes it's impossible and the camera needs to be changed before anything can be done and all of those systems are deactivated until the front forward facing camera has been replaced. I am a mechanic I service a lot of these Honda Odysseys I have a list of items that I find almost every single one has a problem with this particular vehicle I'm sending in about is my personal vehicle and it has had numerous issues that had nothing to do with the operators of the vehicle solely to do with quality of the vehicle front camera is one the sliding door cable housing collapsing too the rear shocks snapping apart at under 50,000 miles front strut mounts going bad at 60,000 miles. There's also an issue with the driver's seat belts fraying in my car in particular frayed in under 12,000 miles more troubling is that every customer I send to the dealer to get things repaired under warranty comes back weather repaired or not without a single item being recorded by the dealer invariably what ends up happening is the dealer will reset some parameter and make the message or error go away. They will then return the car without any documentation stating anything. Once the customer brings it back after warranty is up the dealer charges to replace a repair because the customer has no proof of prior complaint.

I own a 2019 Honda Odyssey elite with 39,000 miles on it. In January 2026, suddenly I had multiple warning lights on in my minivan related to an adas system failure. I replaced the car battery and later determined that the adas camera had failed in the car. In reading online, this is a very common issue with Hondas as the cameras are known to overheat and require replacement. Warning lights: brake system malfunction, adaptive cruise control problem, collision mitigation system problem, lane keeping assist problem, road departure mitigation system problem, auto high beam problem before I was able to get it repaired, the van turned off suddenly in traffic twice while my wife was driving the car while also one of my children was inside, creating an unsafe condition that could have created an accident. Luckily my wife was able to get the car safely moved out of traffic and we stopped driving the car at that point. I wound up replacing the camera and and needing to get it recalibrated so that the car could be drivable. This resulted in the van not being operable for nearly a month. For a car that had 39,000 miles on it, this really should be something under a longer warranty as it could have created an unsafe driving condition for my family. Total cost to repair = $1634. 22.

Warning lights stay on for: adaptive cruise control problem (acc); auto high-beam problem (a); road departure mitigation system problem; collision mitigation system problem; lane keeping assist problem (lkas); brake system lights. Lights will not clear. Dealership diagnosed for replacing monocular camera on front windshield/mirror. Gary smith Honda replacement cost $2364 on 20jan2026.

While driving with my family, my vehicle experienced a sudden and total failure of the front-facing multi-purpose camera mounted behind the windshield. This component is the primary sensor for the Honda sensing suite. The failure caused multiple critical safety systems to become inoperative simultaneously, including the collision mitigation braking system (cmbs), lane keeping assist (lkas), and adaptive cruise control (acc). These systems are essential for crash avoidance and driver assistance.

Driving on the interstate with cruise control. All of a sudden the car braked (no one in front within eye shot) and cruise control stopped. I had to tap the brake manually then accelerator to get the car back under my control. Ever since then I get acc, lkas and other warnings when the car starts up. It seems like the front camera catastrophically failed while driving and almost caused the car to come to a complete stop on the interstate. It was very scary.

Started up the van and the following appears on the dash: acc problem collision mitigation problem lake keep assist problem auto high beam problem safety features unavailable when driving vehicle. In my research this issue has occurred with other owners of the vehicle as well.

After we took the car in all of a sudden randomly these warning lights will come on and my d for drive keeps flashing. Lkas, acc, collision avoidance, auto high beam problem and brake system warning. Sometimes some of them sometimes all of them. I read it’s a common problem but there hasn’t been a recall on it.

Vehicle has code u3000-49 in the mcu module. All vehicle safety systems have shut down and are no longer working until vehicle is repaired (lane assist, collision mitigation, adaptive cruise control, road departure, etc. ) multiplex camera unit is on national back order with no eta available. Vehicle has 5 warning lights and multiple messages that keeping popping up on the cluster.

I am submitting this complaint to report a serious and recurring safety issue with my Honda Odyssey involving the front monocular camera system. After stopping for fuel and restarting the vehicle, multiple warning messages and fault codes appeared on the dashboard simultaneously, including: -collision mitigation system problem -adaptive cruise control problem -lane keep assist problem -auto high beam problem these systems are all disabled due to a failure of the front monocular camera. This failure occurred without warning and immediately compromised several critical driver-assistance and safety features. Based on my research and discussions with other Honda Odyssey owners, this is a known and widespread issue. Honda is aware that the front monocular camera is prone to failure, and numerous owners have reported identical symptoms and error codes. Despite this, no recall has been issued. The required repair involves replacement and recalibration of the front camera and carries an estimated cost of approximately $1,500, which places a significant financial burden on owners for what appears to be a known defect. More importantly, the sudden loss of collision mitigation, lane assist, and adaptive cruise control presents a clear safety concern, especially when drivers rely on these systems during normal operation. Given the safety implications and the number of reported cases, I believe this issue warrants further investigation and a formal recall by Honda. Owners should not be responsible for the cost of repairing a known defect that disables critical safety systems. Thank you for your attention to this matter.

Warning for lane keeping assist, adaptive cruise control, auto high beam, collision mitigation, and road departure all populated at once. The functionality does not work, even regular cruise control without the adaptive feature. There have been many reports of this issue with fixes upwards of $3,000. Appears to be a faulty camera. This is a safety issue and should be addressed and recalled.

I had 5 warnings appeared in the dashboard : -adaptive cruise control problem -lane keeping assist problem -collision mitigation system problem -road departure mitigation system problem -auto high-beam problem and the amber brake system light came on permanently searched the problem on google and reddit found many Honda Odyssey owners having the same problem which is a safety issue some people took their vehicle to the dealership and have been told that the windshield camera is causing these warnings to appear because the camera is overheated by the sun, and the manufacturer did not make the camera well ventilated to dissipate heat caused by sun light.

At restaurant on 6/1/25, backed out of parking spot. Drove about 30 ft to parking lot exit. Turned onto side street to go to light and turn on main street. About 3 or 4 car lengths from exit to light. Side street sloped down about 20-30 degrees. Brakes would not stop van. Not sure if brakes slowed down van as going slow. However, brake pedal pushed hard down to floor but did not stop van. If hit gas pedal van would have accelerated and engine raced causing acceleration and more damage. No damage to back of vehicle I hit. Very minor damage to my van. Tried yesterday and today to replicate (in isolated locations and with no other vehicle near) the van’s conditions at time of incident. I will be contacting dealer. There is no recall. Do not know if anyone else had this problem or if dealer can find any issue. Notifying NHTSA to advise of this potential systemic issue. I’ll follow up with results of interaction with dealer.

The brake system warning light is on. With this, it is showing 5 different issue messages when the car is running. I've taken to the dealer and they are saying there is an issue with the multipurpose front camera. My car is on 39,900 miles.

Ton of warning messages. On the Honda online forum you can find hundreds of people with the same problem.

Without any notable prior messages or symptoms prior to the failure, on [xxx] after dropping off the kids at school and then turning on my 2019 Honda Odyssey ex-l (28,170 miles), the "brake system" light was on and the following 5 dashboard warning lights/messages turned 1) adaptive cruise control problem, 2) lane keeping assist problem, 3) collision mitigation system problem, 4) road departure mitigation system problem, 5) auto high-beam problem. The advanced driver assistance systems no longer works, and it becomes unknown to the driver whether the "brake system" light is being triggered only by the collision mitigation system problem, or an additional problemch as the anti-lock brake system not working. While no accidents occurred, the warning lights add unneeded driver anxiety, which can contribute to a potential safety impact. The problem has been confirmed by the san leandro, CA Honda dealer to be error code u3000-49. Dealer diagnosed problem as "multipurpose camera / millimeter wave radar internal circuit failure" and recommended to replace the multipurpose camera and perform aiming. Dealer advised that safety features will not work. The diagnostic fee was $179. 10, and the repair fee was quoted as $2456. 55 the vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others.

My radar and multipurpose camera need replacement.

We have multipurpose camera failure. No damage or accidents. It just started failing. There are many reports of this and the camera is on back order with Honda. They are charging $2100 to fix it. The official Honda Odyssey forum online has countless complaints on the same issue without resolution by Honda. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering the lives of passengers. Honda has acted in bad-faith towards their customers by designing a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, I. E. , the placement of the radar behind the large, thick plastic h emblem obstructs the radar. I hereby ask that the NHTSA investigate this issue and order Honda to offer a solution in the form of a recall that permanent addresses the problem. Our experience after contacting Honda corporate to get some help is this is a money maker for them.

Took the van to the dealership to fix a recall for the fuel pump. A few days later, error messages popped up saying there are problems with the adaptive cruise control, collision mitigation system, lane keep assist system, and brake system, among others. I test drove it from arcadia to pasadena on both the freeway and the sidestreets without any problems. We took it back to the dealership who assessed it and told us that the multipurpose camera was bad. It would cost us $2100 to get it fixed. We refused. No one was hurt, however, the dealership told me that there is a safety risk to my family if I did not repair it. Attached is the invoice for the last visit during which the dealership gave us the estimate for replacing the multipurpose camera.

Upon starting the car, multiple alerts came on the dashboard reporting faults with multiple systems. There was no damage to the car, it had been parked safely and appropriately prior to starting. Dealership inspected the issue and reported the camera/sensor system in the windshield behind the rear view mirror is faulty. This faulty camera now causes multiple systems off line as the sensor is no longer reliable. This is a safety issue as this sensor assists with split second support to the driver to prevent collisions, leaving your lane or speed adjustment with cruise control.

Within 6 months of purchase (no accidents or related issues), the car starts firing off a wide range of alerts on the dashboard about failures. These include collision mitigation braking system (cmbs), road departure mitigation (rdm), or adaptive cruise control, auto high-beam problem, and lane keeping assist problems. There are many reported issues like this online and it’s a clear failure of on Honda’s part to provide working safety features that they advertise.

Front camera appears to have gone out in 2025. All safety features inoperable and constant flashing of warnings making it impossible to determine if anything is actually wrong. Collision mitigation failure, blind spot failure, transmission failure, brake system failure, blind spot. Those control etc. Honda has confirmed its issue with front camera.

The warning for these adas keeps coming on without any reason.
