Honda (American Honda Motor Co.) is recalling certain 2018-2020 Odyssey vehicles. Water may enter into the rearview camera, which can cause the rearview camera image to fail to display when the vehicle is in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
A rearview image that does not display reduces the driver's view behind the vehicle, increasing the risk of a crash.
Dealers will replace the rearview camera, free of charge. Owner notification letters were mailed August 24, 2026. Owners may contact Honda's customer service at 1-888-234-2138.

Forward collision avoidance, Lane departure, Jul 17, 2024
1.5 weeks after servicing vehicle at the dealership (oil change and tire rotation) Warning lights come on beeping upon starting vehicle. The following systems are malfunctioning... -collision mitigation syatem problem -adaptive cruise Control problem -lane keep assistance problem -road departure mitigation system problem -auto high beam problem. This also removes any ability to use regular cruise control in any capacity (even without adaptive cruise control on) Honda certified mechanic diagnosed code : U3000-49 as a bad Multipurpose Camera Unit. Parts alone cost $1,200 then labor and cost to calibrate (which must be done at dealer). The cost of this repair to MAJOR safety features would be over $2,000. This is a safety related issue that should be recalled immediately. We do not currently feel safe in our 2018 Honda Odyssey, nor do we have $2,000 to complete this repair. Our research (a few screenshots attached) of this malfunction of the Multipurpose Camera Unit shows widespread issues on 2018 odysseys in particular. To me that warrants an investigation and recall. A dealer actually told me "you don't need those features to drive the vehicle". Well, we don't NEED a backup camera and it was recalled. Why? Because we don't want to run over small children. I would like to be able use ALL safety featured on my vehicle. This isn't an entertainment system. It is the major safety feature on our family vehicle, which we saved for years to purchase. We ask that Honda consider the safety ramifications of NOT recalling this malfunctioning camera unit and do the right thing in issuing a recall.

My vehicle started to show warning: Collision MitigationSystem Problem/ Road Departure Mitigation System Problem/ Adaptive Cruise Control Problem / Lane Keeping Assist Problem/ Auto High-Beam Problem. I took it back to Honda dealership and was told the Multipurpose Camera is damaged and needed to be changed. They asked if I have a vehicle accident and I told them I HAVE NOT BEEN IN ONE. I don’t understand why this just starts up all of a sudden and have seen other people complaining of this same problem.

The lane keep assist function via the monocam behind the windshield has failed causing an alert to show up a few minutes into driving that none of the systems related to it are functional. This appears to be a widespread problem amongst owners of the 2018 Odyssey. Additionally, Honda service centers are acting like this is a surprise to them but searching online will results many individuals with the same issue and then being charged 1300-2000 to fix it. Since the features are all safety related I assumed this was where I should submit this. Please let me know if this is not the case.

The contact owns a 2018 Honda Odyssey. The contact stated that upon start of the vehicle, the Adaptive Cruise Control, Lane Keep Assist, Collision Mitigation System, Road Departure Mitigation system, and Auto High Beam system warning lights were illuminated. The contact stated that multiple failures occurred soon after the windshield was replaced by an independent mechanic. The dealer was notified of the failure and informed the contact that the front camera needed to be recalibrated to repair the vehicle. The vehicle was taken back to the independent mechanic where the front camera was recalibrated five times; however, the failure persisted. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 70,000.

It is available for inspection on request. Lost blindspot info, lost use of turn indicators, rear door hatch malfunction, several warnings flash up while driving. I was in a busy area and didn't have a way to signal my movements, screen flashing warnings was terrifying, the van felt like it might turn off at any moment. Before the most recent incident, we had brought the van to Honda dealer for repair, for similar issues that occured at start-up, they found water in the power control unit in rear left area of van that caused corrosion and short-circuit. No body damage or alterations to vehicle. Replaced unit and after rainy weather problems recurred at start up and power down, then while driving, they tested the battery and it was almost dead (the battery was only 1 month old) replaced battery. Problems recurred and water found again. significant leak suspected but not found yet as the service department won't evaluate the seals, and told us it's a body-shop task. summary: intermittent left-side passenger door and rear hatch door malfunction, blind spot system warnings/loss, loss of turn indication, brake system warnings, other system warnings, difficulty starting the car and turning the car off, brand new battery drained while the car was parked and turned off. This manufacturing defect should be addressed by Honda, seals should not fail when exposed to regular conditions. Water should not enter the vehicle and short out an important component leading to several malfunctions that could cause loss of important systems and rear-door latch while driving.

The forward warning system will say brake without anyone or anything in front of you. It will then slam on the brakes. This is very dangerous and has almost resulted in multiple collisions. We have took it to the dealership numerous times and it has not been fixed. I have called American Honda and they will not fix the issue. I get the run around that it is outside of warranty. It was took to them under warranty but was never fixed. The local Honda dealer wants to just try swapping out cameras at a price of $2,500. They do not know if it will even fix it. Now the system has numerous warning lights related to the adaptive cruise, lane keep assistance, forward warning system and lane departure warning. Again I have called America Honda and local dealership. They do not know how to fix it. This is a major safety hazard and they should be forced to repair it under a recall.

10/4/2023 (55K miles), the vehicle suddenly lost power at interstate speed and dropped to three cylinders. Warning lights came on disabling all automatic safety systems. I took the vehicle to a parts store and OBD indicated an oil pressure sensor in VTEC Bank 1. After restarting the vehicle I once again had all 6 cylinders, but all safety systems failures were still indicated on the dash. I replaced the battery (5.5 years old) and all systems returned to normal. After a the PGM-FI update for idle stop issues (recall) was performed at the dealer on 1/31/2024, two days later (2/2/2024) the previous event recurred resulting in severe loss of power and all safety systems indicating failure. I replaced the 4 month old battery under warranty believing the battery had failed prematurely. The problem did not resolve after replacing the battery and multiple restarts. I returned the car to the dealer service center on 2/3/2024 running on three cylinders and then suddenly 6 again after a restart part way there. Dealer diagnosed issue as intermittent fault P2652 Rocker Arm Oil Pressure Switch B (Bank 1) and replaced it at my cost but did not charge diagnoses. Operation returned to normal. ***I have driven Honda vehicles for 25 years with very few issues. Something is seriously wrong in their ECU program/electrical system that causes vehicle to suddenly lose power and safety systems due to an intermittent oil pressure sensor fault. I am a Mechanical Engineer with more than 18 years working in mechanical and electrical aerospace systems. Honda needs to identify the root cause of this failure mode and issue yet another recall to address the systemic hardware and software issues. Both times this occurred, I had 4 young kids in the car and could not maintain safe interstate speed or accelerate to get on the highway.

The vehicle has multiple warning lights and a recall was issued for the MOST connectors upon the initial problem which fixed it temporarily and now it continues to have multiple problems. It shuts off while I'm driving and the steering wheel locks up. It's as if the car is possessed the system screams at you, goes black, turns the music off and on. I have had it at the Honda twice and am taking it again in the morning. I'm afraid to drive my children in it.

Tailgate controller issue. 2018 Honda Odyssey: A day after a day of rain, we went out shopping and stopped at a store. Getting out , we saw "Tailgate Controller Problem" message appear on the dashboard. I tried to open/close the tailgate but it just kept latching and unlatching. I was finally able to get it to remain closed by pushing on the tailgate. After heading to another store, saw a "high-beam problem" message, and another message, so we went home. At night, I noticed the interior ceiling lights going on and off. I went to start the van, and my key fob would not unlock the door. I used the emergency key in the fob and tried opening the drivers door...after 45 seconds of turning left and turning right, the windows rolled down about an inch, then the door unlocked. I started the van and moved it up in the driveway and turned it off, and checked a couple of times all night to see if the lights came back on. The next morning, I had to charge the battery because it was at 3Vs. I drove the van to make sure the alternator was working,and then saw messages: blinking "R" for reverse blinking "D" and no turn signals, and messages appeared: "Transmission Problem". "Keyless Start System Problem","Blind Spot Info System Problem".We dropped the van off at the dealer and it would not lock with the fob, and the center dashboard console (with the navigation menu)remained on with the engine off and door closed. Dealer ordered a Tailgate Controller. When we asked the person at the desk, what the issue was..."moisture got in". I told him there is a discussion on the internet about a (design) leak in the roof causing this issue. He said, the controller is in the tailgate not in the van. But I know its on the side panel. This situation is very dangerous because a week before we had traveled with the van,out of state, on the interstate, trying to get people to airports and if these messages had appeared then, we would have had a very harrowing experience. A message is still seen
Steering, Electrical system, Lane departure, Nov 27, 2023
The electrical system has some weird glitch where it will shut down all the displays and more. The nav display as well as the speedometer area will shut down and restart. I will receive warning lights that many systems like the lane Keeping Assistant and accident braking mitigation systems are offline. Sometimes it will kill the engine too. This is very disturbing and unsafe to happen when driving. It could cause an accident on its own and also negates the extra safety features like LKAS added to make the van safer to drive. The problem was assessed by Honda and they said they could not find an issue originally. There were no codes. Now I am getting more problems and warnings. The dash now tells me "Engine Management System Malfunction". Honda reset this since they could not find a service code. It came back within a week and then my power steering started messing up. It seemed to be when the system was overloaded by going into reverse and switching to the backup camera. The power steering would lurch and stutter. This is very concerning to go out while driving. The final straw is now my high-pressure fuel pump has gone out causing a loud noise under the hood. My vehicle only has 120,000 which I feel is not that old for a Honda. Honda has the van today and wants $1200 to swap out the fuel pump and now they say the "Power distribution module" is causing all the electrical problems which is another $700. My question is: Is this all connected to the same electrical issue? Note: I have a suspicion that the problems are worse when the car gets too much stimulus in the electrical system. Sometimes it seems like the sun at the right angle blinds the front cameras and the system freaks out. Also, changing to reverse and activating the backup camera tends to cause the problem. Possibly even adding devices with carplay could exacerbate it.

Here is what happened: 1). After the car driving for 10mins and engine warms up, stop the car, and turn off. 2). Turn on the car again, it shows message such as "Emissions System Problem", "Transmission problem", "Blind Spot Info System Problem" at the same time. The computer locks the car that doesn't allow the Transmission to change from "P" to "R", "N", or "D" position. The car fails to drive. 3). Leave the car for few hours and let the engine compartment cool down first, turn on the car again and those messages go away, and the car can drive. 4). After driving for a while, it repeats the problem from 1) ~ 3).

Front windshield camera failure (confirmed by local Honda dealership). No known cause and no prior warnings/messages. All warning messages popped up suddenly after the car was parked for the workday. The following functions were disabled by this failure: automatic emergency breaking, lane keep assist, forward collision warning, lane departure warning, cruise control, etc. Part to replace is "on national backorder with no known ETA"

The camera that controls all safety features in my vehicle has an “Internal Failure” this means all my sensors and my dash board is lit up like a Christmas Tree. I took it to the dealership paid for a diagnostic test and found out it was the front camera internal failure, which means all sensors (lane mitigation, braking system, cruise control, automatic dim lights etc), is all not working. HELP please!! As I took it to the dealership even if I pay for the fixing the camera is on National Back Order that being stated it means MANY people are having the same issue, and Honda has no conducted a recall for this HELP us PLEASE!!!

I was driving and all of the sudden the vehicle slowly started losing power. A bunch of lights popped up on the dash and it turns out it was the camshaft and the sensor. The camshaft had been rubbing on the sensor for quite some time causing the engine to malfunction.

When driving the vehicle on September 8, 2023 LKAS (lane keeping assist problem), collision mitigation system problem, road departure mitigation system problem, blind spot info system problem, auto high beam problem and ACC (adaptive cruise control problem) came on. Pulled over and restarted the car and all warning lights remain. Transmission system problem error is now appearing with the letters blinking on the display. Turn the car off and back on until transmission problem error goes away. Vehicle going in for diagnostics early October.

Appears the front radar system fails causing all safety features that rely on data from that radar to also fail, causing a high potential for safety related incident due to reliance on these safety features.

The power tailgate on my 2018 Honda Odyssey EX-L started opening and closing on its own, seemingly at random. The latch would not cinch and the gauge cluster reported an opening attempt while driving on the highway. This failure cascaded and ended up bringing every device on the B-CAN network down, including the instrument cluster, heated seats, power sliding doors, ADAS systems including FCW/LDW/LKA and various telltales and buttons on the dash. Upon disassembly of the interior to expose the affected controllers, I discovered that the power tailgate controller was full of water. There was enough water in it to cause arcing of the power and CAN terminals. I traced the ingress path upwards and discovered a crack in the seam sealer on the roof, underneath the left roof rack rail at the very rear of the vehicle. Water enters under the roof rail, drips down the door hinge, then drips down the body to the cup holder and directly into the controller. To remediate I had to replace the damaged controller and apply seam sealer underneath the roof rail at a cost of approximately $200. I called the local dealer to attempt to report this to Honda but was unable to find the appropriate person. Over a dozen people have reported this issue online and there are pictures of the issue. I posted pictures to one of the links referenced below and have additional pictures. I believe this is a manufacturing defect and not caused by age or use of the vehicle and there is strong evidence it affects a lot of people. The issue will be particularly prevalent when the vehicle is parked outside on a downward incline. I work in a related industry on embedded devices that must meet functional safety standards, and I believe an issue like this would lead to a mandatory safety recall.
