Assist Problems of Honda Odyssey - part 2

The multipurpose camera has an internal failure at 105 thousand miles. This controls the automatic emergency braking, lane keep assist, adaptive cruise control, lane departure warning, and more. This safety features such as emergency braking, lane keep assist, and lane departure warning are important safety features. All of these features help drivers avoid collisions by acting to correct or avoid collisions or accidents faster or earlier than drivers can react. The Honda dealership service department has confirmed that the multipurpose camera had an internal failure, but did not provide a reason and there was no inciting incident during driving or ownership that caused this. The Honda dealership service department has been inspected and diagnosed that the multipurpose camera had an internal failure. No, there were no warning lamps, messages, or other symptoms of the problem prior to the failure. They only appeared after the failure, and the failure happened without warning. The failure first appeared on July 7th, 2025.

The multipurpose camera failed bring down all driver assistance functionality including lane keep assist, emergency brake, auto high beam, parking sensors, cruise control, etc. Fix is outrageously high $2500+. Internet search finds this to be a very common issue and deserves a recall.

The multipurpose camera unit failed in my 2020 Honda Odyssey. This camera is responsible for enabling multiple advanced driver-assistance systems, including the collision mitigation braking system (cmbs), lane keeping assist system (lkas), road departure mitigation system (rdm), adaptive cruise control, and auto high beams. The component has not been replaced yet and is available for inspection upon request. The failure of the camera disabled multiple critical safety systems while the vehicle was in operation. These systems are designed to prevent lane departures, collisions, and unintentional road exits, especially at higher speeds. With the systems offline, I was at increased risk of collision or lane departure, particularly on highways or in low visibility conditions. This malfunction removed key layers of protection that the vehicle is designed to provide. The issue was confirmed by a Honda dealership on August 8th 2025, which diagnosed the problem as a failed multipurpose camera unit. They acknowledged that this malfunction disables all related safety systems. The vehicle was inspected by a certified Honda dealership technician, but not by police, insurance, or the manufacturer directly at this time. Multiple dashboard warning messages appeared simultaneously one day when starting the vehicle, including: "collision mitigation system problem" "road departure mitigation system problem" "lane keeping assist problem" "adaptive cruise control problem" "auto high-beam problem" these messages first appeared on or around the end of June 2025, and the systems were disabled immediately upon the failure.

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.

We get a warning light saying "adaptive cruise control system problem". Van has 4200 miles and it happens during hot days, usually at lunch time. I took it to dealer "Honda cars of rock hill, SC" but they told me there is no code showing up in the van. I emailed Honda America with video but so far no response. The system just goes crazy, beeping and the cruise control is no responsive to cancel button or anything. We are not even using the adaptive cruise control when this happens. After you drive for a while, it goes away, like nothing happened. But when another hot summer day comes, around lunch time, it goes. . . It does it pretty much during high temps. Never in the evening or night time. Here is link to youtube video I sent to Honda: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

5 warning shows up.

When I start the vehicle, I consistently get warnings for acc problem, lake keep assist problem, collision mitigation problem, road departure mitigation problem, and auto high beam problem. This occurs every time I have driven the vehicle for the past week. From cursory research, this issue commonly appears to be related to a failure of the camera module located next to the rearview mirror.

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.

Suddenly the van gave me 5 different warnings as below. 1. Adaptive cruise control problem. 2. Lane keep asist problem 3. Collision mitigation system problem 4. Road departure mitigation system problem 5. Auto high-beam problem on top of these, 'brake system' light also turned on.

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.

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.

I have an intermittent set of warnings on Honda Odyssey 2018 "lane keeping assist problem" "adaptive cruise control problem" "collision mitigation system problem" "road departure mitigation system problem" all at the same time will appear on the dashboard. I had brought it up to the dealership when under warranty and they were unable to resolve it. It comes and goes at random.

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.

Warnings displayed: 1. Auto high-beam problem 2. Adaptive cruise control (acc) problem 3. Lane keeping assist system (lkas) problem 4. Collision mitigation system problem 5. Road departure mitigation system problem 6. Brake system warning (red brake light illuminated) dealer diagnostic: multipurpose camera malfunctioning. Costs $2218 to replace. This should be a manufacturer recall.

Windshield monocular camera has became faulty. No longer have adaptive cruise control, lane departure, forward collision braking. Looks like about a $1,500 expense to fix. Seems like a very common problem.

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. The dealer was never able to replicate the issue as it would go away as soon as the car was restarted. This time, the warning lights would not go away.

Vehicle is indicating all sensing system not working such as lane keeping assist system, collision mitigation braking system, road departure warning system, adaptive cruise control and others. Honda installed a cheap product on this vehicle when it was originally manufactured and is double dipping by selling us in a 7 year period another set of the same cheap product . Dealer is quoting me $3,139. 80 to replace a radar and a camera both at the same time.

Driving on the freeway my lane keeping assistance, automatic emergency breaking, and adaptive cruise control warnings were flashing. The prompts keep my focus off the road as the beeps and flashing orange lights cannot be disabled. During my drive, the multicamera on the windshield seems to be malfunctions and often I would get a signal of on coming traffic and my steering wheel would vibrate to prompt me to move. This can be extremely terrifying and sometimes caused me to swerve, potentially hitting other cars. The multicamera needs to be recalled and fixed.

Front camera stopped working, which appears to be a common problem for Honda, and deactivated all safety features that rely on camera.

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.

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.

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.

8/10 times when turning on and driving the vehicle, an error pops up on the dash indicating the lkas and acc no longer work. Dealer found the code was u3000-49, they could not get it to clear. Sometimes the car will start without the problem, but then at some point through the drive it will occur and lkas and cruise control will no longer be avaliable.

The lkas and several other lights are on in the vehicle and no one has been able to provide any answers as to why. Nor can the problem be fixed. There is also a problem with the transmission. Upon acceleration there is a hesitation that the car will not engage.

Monocular camera failure. Diagnosed by Honda dealership. Safety risk because the adaptive cruise control, auto high beam, road departure mitigation system and collision mitigation system no longer work properly. The warning lamps are continuously on the car, reporting this problem as well.

Multiple warnings regarding adaptive cruise control, lane keep assist, and lane departure warning problems. Honda says it is the front multi-camera. The vehicle works fine intermittently, but doesn’t more often than not. Issue started to occur shortly after a wiring harness recall.

Out of nowhere I received 5 warnings regarding adaptive cruise control, collusion mitigation, lane keep assistant, automatic high beam. . . Etc failure. Upon restarting the car, the warnings would clear itself on occasion but would reappear on following start up.

While driving in a construction zone, the vehicle's lane departure system jerked the wheel and almost made me leave the lane very dangerous. Same vehicle, the a'c was found not operating and a dealer diagnosis found that the system was overfilled and that an electrical connection was not hooked up from the factory. Same vehicle, body panels are not properly aligned from the sliding door to the passenger side door, gap is almost 1/2 inch.

The windshield monocular camera is completely non functional causing several dashboard errors to appear. It very disheartening as this is such a known issue within the Honda Odyssey community and very expensive to replace and get calibrated after replacement. This should be recalled since so many are having this issue. Clearly this is a fault of Honda. It seems that the camera can get too hot being in the windshield and just doesn't work. A big reason why I wanted this vehicle was because of these sensors. Now I can't use them.

2018 Odyssey elite with 43k miles. Apparently, the front facing camera failed and if the camera fails -- which seems to have been reported by many other owners -- it's about a $1700 fix from a dealer. Not only should the camera not fail, but this is happening to cars that are low miles, low use, and the failure affects all camera-related safety features of the vehicle: lane keep assist, adaptive cruise control, lane departure warning, forward collision warning, parking collision warning, and automatic emergency braking.

Front facing camera malfunctioning, and it is available for inspection upon request. This malfunction causing 5 different warning lights to show up on dashboard. Including 1. ) auto high beam problem, lane keeping assist problem, collision mitigation system problem, adaptive cruise control problem, road departure mitigation problem. The issue has been confirmed by the dealer. There were no warning lights prior to the random malfunction. I have not had wind shield replaced (which I have read could mean a calibration of the camera issue), nor has there been any accidents taken place. My safety is at risk as I am unable to use these features while driving unless the front camera is replaced.

The front camera that controls adaptive system died within 4years of owning the vehicle so all the warning lights come on now.
