Warnings problems of the 2019 Honda Odyssey - part 1

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.

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My radar and multipurpose camera need replacement.

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.

I am reporting a serious safety concern regarding my 2019 Honda Odyssey, which poses a risk to me and my family. The issue is intermittent, making it difficult for the dealership to replicate. The problem began when the collision mitigation system warning light flashed, indicating a system malfunction. This was followed by multiple warning lights appearing on the dashboard. At times, the entire dashboard and screen go blank, and all gauges shut off while I am driving on both city streets and highways-though the engine remains on. Additionally, I have experienced the following issues: the steering wheel stiffness when making turns, the vehicle hesitates to accelerate after being at a stop. In December 2023, I took the vehicle to a Honda dealership, where they recommended replacing the front camera/sensor (behind the rear mirror) at a cost of over $1,500. 00. I proceeded with the repair in December 2023. However, the same issues returned in January 2025. This defect poses a severe safety risk, especially when driving at higher speeds or in traffic. Since the dealership has been unable to diagnose the issue due to its sporadic nature, I am requesting an investigation into this matter to determine if other owners are experiencing similar safety risks. Thank you for your time and attention to this issue.

Out of nowhere. . . A bunch of warnings lights have appeared and disabled a lot of the safety features on the vehicle. Adaptive cruise control problem lane keeping assist problem collision mitigation system problem road departure mitigation system problem auto high beam problem the car drives fine but the safety features do not work, along with the cruise control. This is a known issue for Honda and there needs to be a recall before someone get hurt!!!.

The front facing multi purpose camera is defective with a replacement cost of $1800-$2000. It controls all the lane assist, cruise control, braking functions of the vehicle.

My 2019 Honda Odyssey was involved in a total loss car accident recently on Aug 20 2024. The cause was delayed acceleration due to a fuel pump recall by Honda motor corp from Dec 2023; and to date they have failed and neglected to provide the part to repair. For over a year I have experienced delayed acceleration issues with this auto. I purchased this auto new from the local dealer in 2019 and have constantly experienced, reported and paid thousands to repair and address transmission and delayed acceleration issues. Now this resulted in my inability to accelerate from a stop position resulting in another vehicle directly crashing into mine. Researching similar issues reported to the national highway traffic safety administration it appears I'm not alone. In our case - we were in fact "t-boned".

5 emergency lights came on at the same time, we went to the Honda dealer and the problem is the front camera, they told us there, for the diagnosis it was $250 dollars and if we want to fix it it would be $1900, I think that Honda should cover that because it is a car with only 30,000 miles, it is a very expensive repair for a car that is not that old.

While driving the car brakes hard when it thinks that it is going to hit another car even though there is not another car around. We have almost been in multiple accidents because of it. When driving down a winding lane it often shakes the wheel although we are not departing lanes. We do not feel safe while driving the car with this safety feature.

My car experience a sudden and catastrophic failure of the multipurpose camera, part number hp36160-thr-a81. Many of the safety features of my car are dependent on this part, which given the age and low mileage of my vehicle has obviously failed prematurely. The safety features impacted on my vehicle by this part failure include acc, lkas, collision mitigation and road departure mitigation systems. I receive continuous warning lights and alarms while driving the vehicle related to these systems. These warning lights and alarms cannot be stopped. Without these systems working properly the vehicle is not safe. I was told that 8tbwpupd cost roughly $1600 to replace the part necessary for these systems to work.

The following message suddenly appeared one day and since then, they kept coming back on every time starting the car: acc problem, collision mitigation problem, lake keep assist problem, auto high beam problem, brake problem, and sometimes transmission problem as well. After research online, many other owners of the same vehicle had the same issue and which may be caused by faulty connector or faulty front camera component for the hardware issue; or software issue which was on the previous recall for the multi-media issue on the Odysseys. There is a Honda service bulletin 18-006 for the 2017-2018 cr-v models of the same issue/symptoms: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

1. The multipurpose camera, which is needed for the adas to function has malfunctioned. Yes, it is available for inspection request. 2. The malfunctioning multipurpose camera caused the advanced driver-assistance systems (adas) to perform unreliably. Features such as lane keeping assist, adaptive cruise control, and collision warning either stopped working or provided false alerts. This created unpredictable driving conditions, as I could not rely on the systems to detect other vehicles, maintain lane position, or warn of potential collisions. The issue increased the risk of an accident for me and for other drivers or pedestrians, especially in traffic or on highways. Upon doing some research, it seems clear that this is a wide-spread problem, which Honda has not issued a recall about. 3. Yes, this has been reproduced and confirmed by a dealer. 4. No, it has not been inspected by the manufacturer, police, or insurance rep. 5. No, there were not any warning lamps, messages, or other symptoms prior to the failure.

The camera that controls all the advanced driver assistance system fails intermittently. This causes 5 different warnings to come on and all of the safety features bases on this camera to stop working. This is an ongoing issue. An internet search shows that there are multiple Honda vehicles with this problem.

Received several error messages with collision avoidance, braking, lane keeping, front collision avoidance. I took it into the dealership and they quoted me 3k to fix it. I had code dtc u3000-49 multipurpose camera unit/ millimeter wave radar internal failure. They could not explain why it would come back on and work for a while and indicated both systems have to be replaced because of their software. I took the vehicle to dealership two months earlier for loss of acceleration and engine not accelerating when pressing pedal. Alternator replace. Upon searching the internet, this seems to be a common issue with the Odyssey dating as far back as 5 years. My errors are the following: -acc issue -lkas issue -collision mitigation system -auto high beam problem. I am beyond frustrated because these are all safety related systems. A close friend and master mechanic believes that it is an electrical/ software and not a component issue since the components seem to be functioning at times. I am not sure why all of these systems are failing at once.

In early December 2023, while driving, I experienced a sudden malfunction in my lkas system, receiving a notification that it had stopped working without any prior indications. In response, I promptly pulled over, turned off the vehicle, and restarted it, hoping to clear any error messages. Unfortunately, the issue persisted. Subsequently, I took my vehicle to the Honda service center, where I was informed that the front camera was malfunctioning, triggering multiple error messages such as collision system problems, auto high beam issues, and adaptive cruise control malfunctions—all of which rendered these safety features inoperable. The service center clarified that, while it was deemed safe to drive the vehicle, the automatic braking system and front camera features were unavailable, and any necessary repairs would be at my expense. The paperwork provided indicated the discovery of dtc u3000-49, citing a multipurpose camera unit/millimeter wave radar internal electronic failure. Additionally, beyond the lkas system issue, I have repeatedly encountered difficulties with my vehicle's acceleration. Notably, there is a struggle to accelerate from a complete stop, and a significant delay in acceleration occurs when removing my foot from the gas pedal, especially in the middle of intersections. This delay has resulted in near collisions, with other vehicles honking and, at times, coming dangerously close to colliding with my vehicle. Despite reporting this ongoing acceleration problem to the dealer multiple times, the issue persists and has worsened over time. This comprehensive incident report aims to document and address the technical malfunctions in my vehicle, emphasizing the urgent need for a thorough examination and resolution of these safety concerns.

On January 18, 2024 I had the following recalls performed on 2019 Honda Odyssey elite: auto idle stop and the media oriented systems transport (most) communication coaxial cable. Immediately after the recall work was completed, I began receiving an error code "collision mitigation system problem". The error code would flash after this sequence of events: after my car's engine has come to temperature and is warm. I come to a complete stop, my car goes into idle stop and when I release the brake to accelerate and the engine re-engages, this error flashes. And, I can continue to drive. Prior to this recall work, I had never received this error. In addition to this error code, on January 24, 2024, I was at a complete stop on a freeway offramp. When I released the brake and tried to accelerate, my car would not engage and very loud clunk, followed by the orange "brake system" light flashed on. Eventually my car engaged and we were able to drive. The clunk was so loud my teenage children asked me if we were hit by another car. On, Friday January 25, 2024 after dropping the car off at the dealership we were told that "the diagnostics have revealed a 'defective multipurpose camera and aim'. And, the cost to replace is $1793. 77 plus tax.

The van suddenly started randomly throwing up a series of 5 different codes, all relating to the forward camera system. It will appear and disappear at random, showing lane keeping assist, forward collision system, adaptive cruise control, automatic dimming headlights and lane departure system failed. There are tons of issues with the car having bad cables/terminals for the rear camera, a/v systems, and sxm antenna, but Honda refuses to admit that the front camera issue is related.

There has been no incident. And I hope there is not. But the forward camera that assists in the road departure mitigation, forward collision mitigation and lane keeping assist has failed. Also inoperative is the cruise control, auto dimming headlamps and the brake system light is on. I find it hard to believe that after some of the less critical recalls that have been sent out for this vehicle that they don’t address this very important safety system. The camera alone costs $800 and that doesn’t include the cost of installation and calibration. I have a family of six and we use this van extensively. But we cannot afford this repair and are forced to drive with all of these lights on in the instruments. We take extremely good care of our vehicles. It is serviced well and has been in no major accidents. Please help us get action for ourselves and others who are in danger.
