Warnings Problems of Honda Odyssey - part 1

The vehicle will slam on its brakes with nothing around it. This has happened more times than I can count now and has almost caused us to wreck on multiple occasions.

?the multipurpose windshield camera module in my 2019 Honda Odyssey experiences an internal electronic/power failure (diagnostic trouble code u3000-49) while driving. This failure triggers a cascade of warning lights across the dashboard, instantly and without warning disabling the entire Honda sensing driver-assist suite—including collision mitigation braking (cmbs), lane keeping assist (lkas), road departure mitigation (rdm), adaptive cruise control (acc), and auto high beams.

Safety complaint – 2019 Honda Odyssey elite front camera failure I own a 2019 Honda Odyssey elite with approximately 60,000 miles. The front windshield camera used by the Honda sensing system failed. When the camera failed, the vehicle displayed approximately 11 warning messages/errors involving multiple safety-related systems, including the brake system, vsa, eps, electric parking brake, brake hold, hill start assist, and Honda sensing features such as acc, lkas, and cmbs. This was concerning because one camera failure caused multiple safety systems to become unavailable or display warning messages. The vehicle’s driver-assistance and safety functions were significantly affected. I took the vehicle to a Honda dealer, and the dealer diagnosed the front Honda sensing camera as defective and replaced it. The total cost was approximately $2,600, including the camera, parts, labor, and calibration. I believe this is an unusually expensive failure for a critical safety component, especially on a vehicle with only approximately 60,000 miles. The front camera is not a normal wear item and is essential to several Honda safety and driver-assistance systems. I am also concerned that similar Honda owners have reported failures involving Honda sensing cameras. I would like NHTSA to investigate whether there is a recurring or widespread defect involving the front Honda sensing camera on Honda Odyssey vehicles, particularly model years 2018–2020. I respectfully request that NHTSA review complaints and repair records related to this issue and determine whether further investigation or a safety recall is warranted. I am submitting this complaint because I believe owners should not have to pay approximately $2,600 to repair a potentially recurring defect in a critical safety component.

2019 Honda Odyssey ex : sensing camera located behind front windshield failed and stopped working and giving bunch of error messages. Cruise control and other saftey features operated with help of this camera stopped working. The part number is 36160-thr-a11-m1.

In August 202, the multipurpose monocular camera failed. My car is a 2019 Honda Odyssey exl. I was not involved in any accident or incident that would have caused this to fail. When this camera fails 5 warning codes popup: collision mitigation braking system failure , lane keeping assistance system failure, adaptive cruise control failure, road departure mitigation and auto-high beams stop working. The dealer priced the repair at ~$2,100. Many reports are coming up with this failure and it seems driven by overheating of the camera module, a filed camera component, or other unknown reasons.

I am filing a safety complaint regarding a recurring, severe defect involving the 2025 Honda Odyssey's starter motor and the factory-installed auto idle-stop (idle-stop) system. While driving, the vehicle's auto idle-stop system engaged as designed when coming to a complete stop in traffic. However, when trying to accelerate, the vehicle failed to restart automatically. The engine completely stalled out on an active roadway. Attempts to manually override the system and restart the vehicle using the ignition button failed completely, resulting in an immediate and dangerous loss of propulsion. This defect presents a severe and immediate traffic hazard, as it unexpectedly leaves the vehicle completely disabled and stranded in active lanes of traffic. It strips the driver of the ability to clear the roadway to safety, significantly increasing the risk of a rear-end collision. Multiple occupants, including passengers in the rear seats, were exposed to extreme danger due to this sudden propulsion failure. Despite bringing the vehicle to an authorized Honda dealership, the manufacturer has failed to provide a permanent safety remedy. Also Honda corporate has deny warranty replacement for the starter that’s causing the issue.

This vehicle is actively immobilized on private residential property with its central adas safety networks and advanced driver-assist networks completely crashed and offline (dtc u3000-49) and active short-to-ground circuit failures (dtc b2035) rendering the passenger sliding doors completely inoperable, creating an immediate entrapment and safety hazard. These progressive component failures cascade directly from severe environmental moisture intrusion inside the rear tailgate enclosure. This exact water migration vector intersects directly with active federal safety campaign NHTSA recall 26-v-423 (rearview camera failure), which isolates moisture intrusion into the panel housing as the root factory manufacturing defect. A manufacturer franchise location documented active water leakage onto the power tailgate control unit and heavy corrosion on the wiring connector under a previous repair order but performed zero interim moisture sealing, corrosion cleanup, or terminal mitigation, allowing progressive water migration to completely destroy the wiring system harness. Furthermore, american Honda corporate case management explicitly stated on a recorded verbal line that the manufacturer is denying all repair assistance to remedy these cascading safety campaign electrical defects under an active corporate case. The manufacturer is in open default of its statutory federal obligation to remedy a safety recall defect free of charge to the consumer.

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

The windshield-mounted front monocular camera (Honda sensing unit) overheated and failed/burnt out. This failure completely disabled the forward collision warning, automatic emergency braking, lane departure warning, lane keeping assist, and adaptive cruise control systems, triggering multiple safety system warning lights on the dashboard.

Adaptive cruise control, lane keep assist system problem, collision mitigation system problem, road departure mitigation system problem and auto high beam problem.

With a 103,000 on the dash, engine experienced signs on slowing, check engine, abs, adaptive cruise, and steering faults amongst others . No lights prior to the bearing failing. The engine experienced rod bearing failure and left use stranded on the side of the highway. All maintenance was performed at dealership, towed back to dealership where upon inspection rod bearing completely fell apart. Vehicle is still at dealership where a 14,000 dollar engine was quoted.

The contact owns a 2016 Honda Odyssey. The contact stated that while driving 45 mph, the forward collision warning, lane departure warning, engine, and vsa warning lights were illuminated. While at the stoplight, the vehicle started jerking and sputtering. The contact stated that the failure was related to technical service bulletins: 25-060 and 25-061. The vehicle was taken to the local dealer, where it was diagnosed and determined that there was a misfire coming from the engine. The contact stated that there was oil in the cylinder head. The manufacturer was contacted and opened a case. The manufacturer confirmed that the warranty had expired months earlier, and the case was closed. The failure mileage was approximately 162,600.

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.

The front camera is intermittent and sometimes it works but other times I get 5 error messages when I start my car: adaptive cruise control problem, lane keeping assist problem, collision mitigation system problem, road departure mitigation system problem, auto high-beam problem. In reviewing online, it seems like this is a very common problem with all of these models. Since the repair rate is over $1000 you’re going to have a lot of vehicles on the road without the safety features working. Since it’s intermittent, there’s something with the connection between the camera and the computer. If the camera were broken, it wouldn’t work at all. Any people say they can bang on the camera but that doesn’t seem like a safe fix. I believe this needs to be investigated.

Multipurpose camera failure causing multiple displays on dashboard.

After the vehicle is off, and after the Smart key fob is removed from the vehicle, the dashboard will flicker, the alarm sometimes goes off and the headlights turn on draining the battery and leading to me having to jump the car to get it started. This makes the car undependable as it could happen after driving somewhere and leave myself or my wife stranded. I have taken this in to the Honda dealership but they noted that it did not occur when they were servicing the vehicle and they weren't sure what the issue could be. Many times the check engine light, fcw and ldw lights will come on and then reset after the car has been driven.

I own a 2018 Honda Odyssey ex-l (VIN [xxx]). The vehicle experienced a sudden loss of power and entered limp mode, with multiple safety and driver-assistance systems shutting down at once (adaptive cruise, braking assist, lane/road departure mitigation, eps, etc. ). A Honda dealer (allen Honda, college station, TX) retrieved dtc p0369 and documented that the front camshaft is worn and has thrust forward, contacting the camshaft position (cmp/tdc) sensor and damaging the thrust plate. The dealer is recommending an internal engine repair costing several thousand dollars. I am very concerned because Honda has already acknowledged serious engine defects in this same j35 v6 family under recall 23v751 (connecting rod bearing wear leading to engine damage and stall) for 2018–2019 Odyssey, yet my dealer states my VIN is “not part of the recall” and that this is a “separate issue. ” in practice, I am seeing a major internal engine failure that causes sudden derate and disables multiple safety systems, but I am being told there is no recall coverage or assistance simply because my individual VIN falls outside Honda’s current recall production range. I am requesting that NHTSA review this incident as a potential recall exclusion problem: owners with the same engine family and serious internal failures are being denied recall coverage on a technical VIN cutoff, even though the safety consequence—loss of power and shutdown of critical safety systems while driving—is similar to the failures already recognized under recall 23v751 and the ongoing engine defect investigation. I believe this situation may warrant expansion of existing recall coverage or a new recall campaign for currently excluded vins like mine, and reimbursement for owners who have already paid for these repairs.

I believe it is the windshield monocular multipurpose lkas acc camera. This sensor has malfunctioned for the past two moths and I've tried everything to fix it short of replacing it, which is ridiculously expensive. This is such a common problem on this make/year of vehicle. My car only has 75,000 miles on it.

My 2018 Honda Odyssey ex-l has an ongoing Honda sensing failure. Adaptive cruise control, lane keeping assist, and forward collision warning cannot be activated using their controls. No dashboard warning lights or error messages are displayed. Honda of lake jackson stated that it could not perform further diagnostics. These driver-assistance and safety features remain unavailable during normal vehicle operation. I am reporting the problem because multiple Honda sensing functions cannot be turned on or used.

I own a 2026 Honda Odyssey elite. The vehicle has unexpectedly applied the brakes while driving even though there was no vehicle, pedestrian, or obstacle in front of me. The braking event occurred without warning and without any legitimate reason for the forward collision avoidance system to activate. I first reported this issue to my Honda dealership on June 2, 2026 and again during subsequent repair visits. Although the dealership was initially unable to duplicate the concern, the issue remains unresolved. Unexpected braking at highway speeds creates a serious safety hazard because it increases the risk of a rear end collision and could cause other drivers to take evasive action.

I was driving down a 35mph road, the car in front of me slowed down, I was about 2 car lengths behind it. No notice, no warning, my Odyssey slammed on the brakes and brought me to an abrupt stop with no notice and no need. Everything in the van flew forward and in the floor. Luckily there was no one directly behind me. It gives me serious whiplash when this happens and it is uncalled for, the car in front of me did not stop it only slowed down, there was plenty of room between our vehicles (we were only going about 30 mph) and there was absolutely no warning- just bam! and my van was stopped in the middle of the road. Something needs to be done about this, someone is going to be killed! I took it to the dealer the last time and they said the van did not record it. So another easy out for Honda! and nothing they can do. . .

The monocular collision-avoidance camera 36160-thr-c01 has died on my 2020 Honda Odyssey ex-l. As a result, the following safety features have deactivated causing serious concerns for my safety on the road: acc problem collision mitigation problem lake keep assist problem auto high beam problem the car is not even 6 years old and this $1000+ defective camera has rendered my car not up to safety standards.

The forward facing adas camera has been reporting u0104 error. This resulted in many advanced safety features failing, including adaptive cruise control, automatic emergency braking, forward collision warning, and lane departure warnings. The problem was confirmed and repaired by a independent service center. The problem first appeared on June of 2026.

Multipurpose camera is defective- broken after only 80,000 miles. No longer functions at all. No automatic emergency braking, no forward collision warning, no lane departure warning, no lane keeping assistance, no adaptive cruise control. Dangerous now without all those computer controlled safety functions. $2400 replacement. I don’t have $2400.

Forward camera issue. Brake system light turns on and cruise control, forward brake warning, and lkas all stop working.

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.

While driving in normal traffic, when I come to a complete stop and keep my foot on the brake, the auto idle stop system activates as designed. However, when I release the brake to continue driving, the engine intermittently fails to restart properly. Instead, it repeatedly attempts to restart, cycling on and off several times before shutting down completely. When this occurs, the vehicle becomes disabled in traffic and does not respond as expected. It can take multiple attempts and a significant amount of time before the engine finally restarts, leaving me stranded in intersections or in moving traffic. This creates a serious safety hazard because surrounding vehicles continue moving while my vehicle is unable to move. This problem has occurred multiple times under normal driving conditions and is not an isolated incident. During one occurrence, the vehicle failed to restart after the auto idle stop system activated, leaving my vehicle disabled in traffic. As a result of this incident, my vehicle was involved in a collision that **damaged the front and back bumper**. Fortunately, no one was seriously injured, but the incident clearly demonstrates the significant safety risk associated with this defect. The vehicle is currently at an authorized Honda dealership for diagnosis and repair. I am submitting this complaint because a vehicle that unexpectedly shuts down and fails to restart after auto idle stop activation presents a serious safety hazard. I am concerned that this defect could lead to additional crashes, property damage, or serious injuries if it is not corrected.

I was driving on the street about 15 miles per hour when the car sensor sensed something in front of my car and stopped automatically when there was nothing in front of me. Almost caused a rear-end accident, luckily, the car behind was able to stop.

The vehicle’s front camera/Honda sensing system has failed, causing multiple safety features to become unavailable simultaneously, including forward collision warning, collision mitigation braking, lane departure warning, lane keeping assist, adaptive cruise control and related systems. The failure produces multiple warning messages and disables safety systems that the vehicle was equipped and marketed with. This is a recurring issue reported by other Honda owners and is currently the subject of a proposed class action lawsuit, jones et al. V. American Honda motor CO. , inc. , case no. [xxx]. The lawsuit alleges a defective front camera system affecting 2018–2025 Honda vehicles, including the Odyssey. I believe this constitutes a safety defect because the failure can occur unexpectedly and simultaneously disables multiple driver-assistance and collision-avoidance safety systems. I am requesting that NHTSA investigate this issue and require Honda to issue a safety recall and provide a free repair. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle is showing persistent electrical and communication fault codes involving the ecm, abs, and eps systems, including p16e2, p16e5, p16e7, p16e8, u0401, and u0416. These codes return immediately, which suggests an active fault rather than a temporary low-voltage condition. The issue appears to involve the battery sensor and/or the related communication network between control modules. Because the faults involve abs and eps communication, the concern is that braking-related or steering-assist systems may not be receiving correct data. This creates a potential safety risk because the vehicle may experience intermittent or unreliable control-module communication, which could affect steering assist, braking-related warnings, or overall drivability. The warning lights and diagnostic codes first appeared before the vehicle was put back into normal use and have continued to remain present. The problem has been reproducible because the codes reappear right away after being cleared. No dealer or manufacturer diagnosis has been confirmed yet, so the exact root cause remains unresolved.

The electrical component is failing. I have brought in this vehicle 2 times for failed electrical issues over several years (around 2 years), and it only has 52,000 miles currently. The back up sensors no longer work, as well as warning lights for the following began to appear a year ago: collision mitigation, adaptive cruise control, lane keeping assist, road departure mitigation. Sometimes, our electrical side door will not close and will keep opening when trying to shut. This electrical issues has been draining our battery, and while driving, my car shut off in the middle of the street while I was waiting for a light. After a few attempts, I got my car started again. We replaced the battery, and a few days later the car would randomly turn on and I could not use an electrical key to open the car door. Only way to open it is with the physical key. The battery had to be unplugged in order to stop the car for randomly turning on. All electrical systems would turn on in the car, including the alarm and radio, even if the radio had been off when the car was last turned off. The car has been inspected by Honda mechanics, who told me the electrical component is dying, but they don't know why, the car isn't that old, and it has very few miles on it.

When those error codes appear, those safety features become unavailable during driving. These error usually come up when I just start the car.

Monocular camera code set and several dash messages - failure of acc, fcw, lka.

On interstate 65 4/4/2026 during light traffic, after a rain storm, however with no rain currently occuring, our vehicle experienced an event where the collision avoidance system dropped out speed from 70 miles an hour to 35, nearly causing a rear end clission with a vehicle behind us. The dashboard made no indication of any occurance, and the breaking seemed to occur with no indicator of there being anyting in front of us at the time of the incident. This has occured before however after rainstorms, and while attempting to make left hand turns. This however was the first incident in which it clearly caused a near miss collision event.

While driving on a clear road, with or without heavy traffic, the collision mitigation warning shows up on the dashboard display. Sometimes the warning for the collision system goes off and the system tries to brake and jerk the wheel. If I have the wheel firmly I can correct it and it resolves. It can happen on a clear road with no one around or in heavy traffic. Yesterday it happened in a single lane with barriers on both sides, a road around logan airport in boston, with no vehicles ahead of me. The car tried to steer me into the barrier. I was doing less than 25 mph. The warning had been going off for a while but now that the steering and braking are involved it’s much more serious. I reported it to the dealer. They said they did a system check and couldn’t find a fault. The braking and steering problem first occurred about a month ago. The warning by itself has been happening intermittently for over a year. This happens even when the collision mitigation system is turned off. This is a terribly unsafe issue. If my wife had been driving I don’t know if she could have corrected. Please act and issue a recall!.
