We bought this van with a clean bill of health as far as accidents and single owner prior to us. The car had a documented maintenance history but after 5k miles of driving it the active cruise control began to through all kinds of errors. I researched this issue and find that many more Honda owners with active cruise control have the same issue. A few customers say that they had their front camera replaced and calibrated for a cost of about $1,600. 00 only to have the error show up again. I am writing this message to report that in my case I have found a work around. It’s not a permanent fix but points to Honda’s computer throwing a false positive error that is costing a great deal of money to Honda owners. On our van when this error happens, I force a diagnostic scan followed by a forced computer reboot and the warning lights are fixed an all equipment back to working. It’s horrible to read that Honda charges $1,600. 00 to replace perfectly good parts in all their line without taking the time to truly diagnose their issues with acc errors and do good to their customers. I hope this helps reach someone who can further investigate this issue with Hondas. In our family’s case we are lucky that I have an it background and was able to find a fix for this issue without any costs to our family financials and avoided paying Honda to replace perfectly working components due to their lack of knowledge of how their equipment works.

The multifunction forward looking camera in the top of the windshield developed an "internal fault" and either needs replacement or these safety features will fail to work. These safety features allow me to avoid accidents. The problem has been confirmed by the dealer. There are warning lamps that state that these features are no longer working.
The following safety warnings were displayed on my 2020 Odyssey dashboard as early as January 2025: road departure mitigation system problem auto high-beam problem adaptive cruise control problem lane keeping assist problem collision mitigation system problem currently, the warning messages are displayed continuously without fail upon starting/driving the vehicle. Per my diagnosis through my local Honda service, it is an internal failure with the front-facing camera associated with these safety features.
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. Faulty part and I know this is happening a lot.
I am writing to report a significant safety issue with my 2020 Honda Odyssey. The front assembly assist monocular camera (oem part 36160-thr-c01-m1) has failed, causing the loss of several critical safety features, including auto high beam, lane departure warning, adaptive cruise control, collision mitigation, and lane keeping assist system (lkas). The local Honda dealership diagnosed the issue as an internal fault in the camera unit. Through research, I have discovered this failure is not an isolated incident. Numerous reports from other Odyssey owners highlight similar issues with the camera leading to the deactivation of these safety features. For example, discussions on the Honda Odyssey forum and other online platforms describe widespread failures of front-camera-dependent systems, including lane-keeping and collision avoidance features. These failures compromise vehicle safety, potentially increasing the risk of accidents. The camera’s malfunction disables essential systems designed to enhance driver awareness and prevent collisions, leaving drivers vulnerable in critical situations. I respectfully request that the NHTSA investigate this issue, as the consistency of these reports suggests a systemic problem. A recall or corrective action may be necessary to ensure the safety and reliability of these vehicles. Thank you for your attention to this important matter.
All of a sudden warnings appear related to collision mitigation system problem lane keeping assist problem auto high beam problem adaptive cruise control problem road departure mitigation problem this is a major issue. I don’t feel safe driving this car with my family. Therefore NHTSA should get Honda to issue a recall for this vehicle given the magnitude and sheer scale of the problem. Below is one of many such forums where people who model years 2018-2020 have the exact same problem. . Read more...
The multifunction camera which is responsible for adas features suddenly failed.
Several engine failures, starting one month after purchase in September 2020. Multiple system failures (all on video) leading to very poor acceleration and operation. No compression in engine and only able to go 20 mph. White-allen Honda made four attempts to solve the matter over the course of two years. The dealer has had the car a total of 120 days. Then end of December 2024 then engine began making a knocking sound and I was told it needed at new engine, to the tune of $10,000. 00. Then I see a recall for a similar issue but only up to 2019 Odysseys. Please help find resolution for this.
Acc system started giving errors, diagnostics ran at Honda pointed to multi function camera. System was quoted for replacement at 1500 this seems to be a big problem across these models. Please investigate.
It seems our multi-purpose camera is malfunctioning and therefore causing all of the systems to go offline and light up on the dashboard when we turn on the car. It seems the only solution is to replace this. That seems insane that we should have to pay for this if this is a major safety feature of the car and one of the reasons we purchased the vehicle.
The multipurpose camera above the rearview mirror has stopped working. It controls several systems including; adaptive cruise control, automatic brake system, forward collision warning, lane keeping assistance, lane departure warning, automatic high beam control. Every time I start the vehicle I have to clear 6 different malfunction warnings and non of the effected systems will function. There is an increased risk of accidents. I just had a vehicle diagnostic ran at flow Honda of charlottesville va and they quoted me a price of $2,060 to replace the part.
There are five warning indicator on the dashboard complaining about adaptive cruise control, automatic emergency braking, forward collision warning, lane departure warning, and lane keeping assistance. I took the car to the Honda dealership, and they acknowledged that they were due toan internal failure of the multipurpose camera.
On 6-11-24 the warning lights cycle through auto highbeam problem lane keeping assist adaptive cruise control collision mitigation system problem road departure mitigation system problem earlier in the day I had maintenance at the dealership performed on my car: brake fluid , trans svc,new tires and alignment, oil change and rotate tires, ac filter change, air cleaner element replaced. I went back to dealer on 7-1 and was told it was a multi purpose camera failure. This had not previously occurred until immediately after the maintenance work was performed.
At random the following would come on when driving or when starting the vehicle up. It would also reset itself at random. Very scary when you have small children in the van. 1. Collision mitigation braking system (cmbs) 2. Road departure mitigation system (rdm) 3. Lane keeping assist system (lkas) 4. Adaptive cruise control (acc) 5. Auto head lights the vehicle has not been in any collision. This started after a required update was installed. The code reader scan code does not match what is being stated. When you are using the cruise control then it would turn off. Brake warning will not work. The cable harness for the audio for the entire van was redone last summer 2023.
Multipurpose front camera failure causing adaptive cruise, lane keep, auto highbeams, and collision mitigation to be disabled at 51k miles, error code u3000-49.
In my area, there has been lots of heavy rain. There was a water leak on the interior rear driver side, causing the tailgate control module (tcm) to fail part # 74970-thr-a12 the tailgate trunk or 5th door is not working, will not open, will not activate. I took my 2020 Honda Odyssey my local dealership but no help. Many vans from Honda, years 2018-2021 are having this very same issue. Please help me resolved this matter. Honda should have a recall on this and replace at no charge.
The entire adas system has begun loosing sensing capabilities for a time period but start working again later. It comes and goes regularly at this point. This inconsistency could cause and accident. There are system problem warning lights on the dash when the system is down. The car is too new for this issue. The dealer reports that the front camera is the issue but I would think it has more to do with the wiring possibly shorting out.
Lkas, adaptive cruise control, forward collision warning, automatic emergency braking, lane departure warning all malfunctioned. Dealer inspected and determined it is an overheated camera that controls all the mentioned safety functions. This happened while driving on highway and has never worked again. I did confirm with the dealer this is the 3 instance they have seen of this in the past 3 months.
Driving on the road and heard static noise from the infotainment system after an update. Few minutes later the dashboard had multiple warnings and disabling the entire advanced driver assistance systems (adas). The Honda dealer inspected the front camera in the top of the windshield and said it needed to be replaced.
After the last recall I had corrected by honds, I started having issues with my lkas system. The following notifications started coming periodically and now they always come on every time I start my 2020 Honda Odyssey. Adaptive cruise control, lane keeping assist, collision mitigation system, road departure mitigation system, and auto high-beam. The local Honda dealership quoted $1400 for a new camera.
