Blind Spot Detection Problems of Honda Odyssey - part 1

After the most/fakra recall (NHTSA 23v-431) was completed, the center display showed a most bus/network loss message, then the infotainment system went dead and will not power on. The dealer would like 1800$ to repair this already "repaired" safety system. The rearview screen is unavailable when the screen is blank which is the same fmvss 111 rear visibility failure the recall was issued to correct. TSB 20-049 describes the same network loss/ display condition. The recall repair did not permanently fix the most ring.

?I am writing to issue a formal complaint regarding gross negligence, logistics failures, and deceptive service practices surrounding mandatory recall work on my 2020 Honda Odyssey. ?1. Failure to complete recall software work after overnight retention on Tuesday, September 1, your service department texted stating: "the software update did not finish. We do need it overnight. " we agreed to leave the vehicle. However, upon pickup, the infotainment display confirmed that the update was never completed and remains stuck at step 5/6 (system update 24084. 7 / front control box b. 1. 4. 6). Retaining a customer's vehicle overnight under the guise of completing software work and returning it unfinished is a direct misrepresentation of labor performed. ?2. Extreme logistics failure and disregard for customer time at 12:55 pm on Wednesday, September 2, your department texted: "ready to go now!" my wife arrived promptly, yet your staff forced her to wait until 2:40 pm—nearly two hours later—before physically releasing the car. This gross delay caused her to miss our children’s school pickup, forcing me to leave my workplace unexpectedly to handle child transportation due to your operational incompetence. ?3. Cascading network faults and critical safety systems disabled prior to service, the dashboard displayed minor sensing suite warnings, for which your department quoted an exorbitant $250 diagnostic fee. Upon picking up the vehicle, the dashboard warning count escalated from 5 to approximately 9 active system failures. Due to the interrupted ecu software installation corrupting the can-bus network, the following primary vehicle controls are now completely inoperable: ?supplemental restraint system (srs / airbag) (newly triggered post-service) ?vehicle stability assist (vsa) system ?automatic brake hold system ?electric parking brake (epb) system ?electric power steering (eps) ?hill start assist ?Honda sensing suite (lane departure, collision mitigation, road departure) ?releas.

The blind-spot monitoring system on our 2026 Honda Odyssey elite fails to operate properly in hot weather. When ambient temperatures are high, the system does not detect or alert to vehicles in the adjacent blind-spot areas, and an error message appears stating “blind spot detection unavailable. ” this failure increases the risk of collisions during lane changes or merges because the driver does not receive the expected visual or audible warnings of vehicles in the blind spots, potentially endangering the occupants of this vehicle and other road users. ??????????????????????????????????????????????????.

My entire adas system malfunction and it started listing 7 warning alerts. I googled and it seems like is a common theme with this vehicle.

The monocular camera (multipurpose camera secured under the rear view mirror) has failed. This disables the following" collision mitigation braking system (cmbs): detects obstacles or vehicles ahead and helps brake automatically if a collision seems likely. Forward collision warning (fcw): works with cmbs to send visual and audible alerts if you get too close to a vehicle in front of you. Lane keeping assist system (lkas): adjusts steering torque to help keep your van centered in a detected lane. Lane departure warning (ldw): alerts you if you drift across detected lane lines without using your turn signal. Road departure mitigation (rdm): applies steering help or braking if you drift off the paved road entirely. Adaptive cruise control (acc): maintains a safe, set following distance behind a vehicle traveling ahead of you. These systems are helpful in keeping you safe while driving. The problem with camera failing cause these system warnings to populate on the dash. This is distracting. This has been confirmed with independent service center. Has not been inspected by manufacture. Started August 21. Quoted $2200 to replace and recalibrate.

Our van recently started flashing multiple warning lights every time we started it up. These include "collision mitigation system problem", "auto high-beam problem", "road departure mitigation system problem", "lane keeping assist problem", "adaptive cruise control problem", and also alerts that there is an issue with our brakes. We took the van into our local Honda dealership and were told the adas camera was broken and would need to be replaced. We were told this would cost $2,733 and that there's a chance we will also have to replace the windshield (which is physically fine) for another $1200. The camera breaking is not normal maintenance or expected due to wear and tear. There is nothing physically wrong with our windshield, we have had no accidents, we have kept up on all needed vehicle maintenance. It's my understanding the location of the camera is simply causing it to overheat and blow out the electrical system. Additionally concerning is that even if I did have the money to fix the issue Honda does not have any cameras available. They are on backorder. It means as a driver to three small children I have to assume the nonstop alerts are all benign for at least a month. In the off chance there is a true safety concern such as brakes malfunctioning, I will not know as the alert system is going off at all times.

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

Multipurpose camera stopped working. No direct physical damage to camera so it shouldn't need replacement after 6 years. Others with Honda Odyssey have reported similar defect.

Front camera intermittently works after NHTSA recall number 26v-227 software update. Adas systems may turn on or off while driving. This issue may not have anything to do with the update, but Honda is aware of the front camera problem. Affects: auto high-beam problem adaptive cruise control problem lane keeping assist problem collision mitigation system problem road departure mitigation system problem there has been a class action lawsuit filed against Honda by California June 2026.

Collision mitigation system problem, auto high beam problem , lane keep assist problem, adaptive cruise control problem, road departure mitigation problem. All of these lights came on at the same time then a transmission problem light came on. Was told by a mechanic that Honda has an issue with a lot of these because of where it sits directly in the sun. All of these problems seem to be connected.

Since purchasing the van, have reported intermittent hesitation to dealerships. Never duplicated at dealership. Eventually, fuel pump replaced under recall. Still had intermittent issues. On June 11,2026, while on the highway, van had slight hesitation and codes started going on dashboard. Got off the highway and the van limped into a nearby home depot parking lot. Had it towed to hill country Honda where they diagnosed a bad map sensor. When told it was ready for pick up, informed that the wiring harness was pinched. The technician stated that he had straightened the wiring and when I inquired about it, told that particular wire had to be cut out and replaced. Informed that I would likely have further issues with van and recommendation was to replace the whole wiring harness. I asked how it was pinched and told that it was probably done at assembly point and not noticed since it was under other components. I called Honda cares as recommended to see if they could do anything for the van but Honda said the van was not under warranty so no assistance was provided. The van has 74,000 miles and always maintained by dealerships. Honda cares said outside influence was the reason nothing could be offered. I believe that Honda is responsible for this situation and I have known 3 different 2019 owners who shared hesitation issues as new owners. Rear speakers are playing very low and told it might also be affected by wiring harness but I don’t think I should spend $4500. 00+ to fix this problem.

I was driving on a highway and all of a sudden, I see three warnings appearing on my dashboard - "emission system problem", "blind spot info system problem", "transmission system problem". I continued driving but then my vehicle started behaving weird. It started shaking while driving. Luckily, I was close to my exit and l somehow managed to take the exit but I wasn't able to move forward when the road was uphill. I somehow managed to park next to a house and walked back home. It was a really scare drive from the time those errors showed up to when I parked. This all happened few minutes ago. Here below is a thread where I can see others having this problem. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

The vehicle started to have failing sensors all of a sudden. I tried a new battery but the codes returned. All adas systems tied to the camera module all went out. I had 5-7 warning lights for all driving functions. Additionally the seat belt buckle is not always clicking in properly. The belt about half the time is not retained in the buckle section.

The blind spot system was a problem when I purchased the car, it spent 15 days in service in the first 30 days of ownership to address the issues. Now, I after another light came on I discovered 9 open recalls on the vehicle that were not disclosed prior to purchase.

We went to a car wash and that day after the car wash we started getting 6+ error message codes for adaptive cruise control, lane assist, lane departure, blind spot, rear cross traffic, etc. Our tech that we took it to says they have seen this happen nation wide on these vehicles.

My vehicle started cycling between all of the check engine types of lights to include the emissions system. When taking it to my local Honda dealership, they determined that it was my front camera (multi-purpose camera internal failure). After some research and speaking to the service department, this major safety failure has been happening to many other Honda vehicles. The emissions system failure seems to also be a faulty design. I feel that the camera system failure could have resulted in an accident or major injury. And of no fault of my own. My vehicle is regularly maintained and is merely 6 years old. I should not be replacing a mayor system like the front camera every 6 years.

The multipurpose camera failed. Searches online and discussion with the dealers show this is a common problem. Result is shutdown of collision mitigation systems, blind spot indicators, lane divergence system, auto high beam, etc.

Improper seal on the seam (?) above let water leak into my power tailgate control module. It caused all the dash lights to sporadically rapidly flash, told me I have a transmission problem and my blind spot warning didn’t work right. Pulled out the tailgate module to find water in the module with a failed circuit board. Also wires leading into the module were wet.

The vehicle’s blind spot warning system intermittently fails during normal operation. The warning message “blind spot information system problem. See your dealer. ” appears after driving or after restarting the vehicle. The system may function initially (for example, when leaving a garage), but then disables itself during driving or after the vehicle is parked and restarted. The issue first occurred within the first week of ownership and has persisted and become more frequent over time. The vehicle currently has approximately 4,500 miles. This failure affects a driver assistance safety feature intended to warn of vehicles in adjacent lanes that may not be visible to the driver. The malfunction creates a safety risk because the system becomes unavailable unpredictably during normal driving conditions. The failure is intermittent and cannot be consistently reproduced at a service appointment. The vehicle has been presented for service; however, the condition could not be diagnosed because the warning was not active at the time of inspection. The dealer advised that the issue could not be evaluated without the warning present. Proposed options included leaving the vehicle for an extended period to attempt to reproduce the intermittent condition, or returning when the warning is active. Due to the unpredictable and intermittent nature of the failure, this approach has not resulted in a diagnosis or repair. The failure remains unresolved. The system failure occurs during routine commuting and affects the ability to safely monitor adjacent lanes when changing lanes.

The contact owns a 2026 Honda Odyssey. The contact stated that while driving on several occasions at various speeds, the blind spot monitor became inoperable with the message "blind spot information systems failure - see dealer" displayed. The contact also stated that while in the driver assist mode, the message "system could not be retrieved - please try again" was displayed. The vehicle was taken to a dealer where it was determined that a systems update was needed but was not currently available. The vehicle was not repaired. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was 6.

The tailgate control module has been water damaged and needed to be replaced twice. My local Honda dealership was unable to correct the issue and stated that it is due to a water leak in the frame of the vehicle/tailgate. The dealership has identified the tailgate control module as the cause of the electrical issues causing the battery to die, and advanced safety features to malfunction. Warning lights came on for break system problem, lane departure mitigation system problem, and many other systems all caused by the tailgate control module being water damaged from a leak in the frame.

The front right sensor goes off randomly. Sometimes all day long for days, then nothing for a week or 2 then back to it. Various lengths of time, usually stressfully long times, with nothing aroundcausing stress and making fucus hard. It started a few months after getting the van. We cleaned it, had the dealer inspect it and no one has ever figured out why we have to live with this blaring warning alarm. The dash says object warning with it and if I close that out nothing stops the alarm but putting it in park which I can't do on the interstate or in pickup line at school.

2020 Honda Odyssey ex lkas, collision avoidance, auto high beam etc. Warning lights to cycle continuously. Had my Honda mechanic check problem and camera monocular, forward facing camera causing issues and requires replacement. This is only a 5 year old vehicle with 60,000 miles on it! Honda and many used auto parts want upwards of $850 for camera and then as much as $1500 to replace. This is a serious safety issue. None of this vehicles safety assist items work without this camera.

Blind spot monitoring system does not register vehicles sometimes. Sometimes when passing a vehicle, light does not illuminate. Sometimes cars will pass the vehicle and light does not illuminate.

Multiple warnings on dashboard due to windshield camera malfunction. Many vehicles of the same model have this problem. This is a part defect and should be recalled. Thank you.

One light on dashboard lit up, started as "blind spot info system problem", light would go on and off for couple of years. Now every light on dashboard lights up, including lane assist, blind spot infor system problem, forward collision warning, adaptive cruise control problem, rear cross traffic warning, lane departure warning.

The camera controlling many systems regarding safety failed and caused numerous warning lights to come on. Complete camera replacement was necessary.

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.

Camera is faulty. Many owners report a similar problem.

All of the warning lights shows up on the dash board. Honda told me it’s related to a bad multi purpose camera. None of the safety features or cruise control will work until the camera is fixed.

Center camera has gone out. Millions of vans in the same position as me.

Hello, my front collision camera is not working and I am getting all sorts of safety related error codes. I took it to Honda for an evaluation and they told me I would need to $1300 to fix part number 36160-thr-a74. As of now all the safety features have been disabled. These are the codes I am getting: adaptive cruise control automatic emergency braking blind spot warning forward collision warning lane departure warning lane keeping assistance.

Was driving on my way to work and I heard a sharp sound while going up a hill. I then got warnings that said transmission issue, pull over immediately when safe and the car shifted itself into neutral. I was in the middle of traffic and lost all acceleration controls, while being forced out of the drive gear. I lost all speed and had to move through traffic and get to a side street. The same thing happened to me about a year and a half ago. It was covered by a warranty but I still was experiencing losses of car power or stalling.
