Automatic Emergency Braking Problems of Honda Odyssey - part 1

One morning, with no prior issues, we started driving our van and it suddenly displayed several warning lights, including brake system, adaptive cruise control, auto emergency braking, forward collision warning, lane departure warning, and lane keeping assistance. We took it to darcars Honda in bowie, MD who diagnosed it as a front facing camera failure. The dealer replaced the camera and kept the old one. This failure in a six year old van increased the danger of collision while operating the vehicle.

I was driving forward in the left lane, no cars in front of me. A garbage truck parked in the middle yellow lane to my left, a moving city bus on my right lane, but they were a bit further back, not driving next to me. There was a cae behind me. Was going at 25mph, then suddenly the automatic brake stopped my car. I didn’t understand why. It happened for a good 3 seconds. Then I was able to continue forward. So scary!!! no one close to my left or right or in front of me. The car behind me almost hit me because of the automatic brake.

Front windshield mounted sensor failure on 2020 Honda Odyssey. Disabled Honda sensing safety suite which included lane keep assist, adaptative cruise control, auto high beams which all triggered warning messages on the dashboard which all occurred at the exact same time. This problem has been reproduced an inspected by Honda of frontenac.

When attempting to accelerate after completing a stop, there was no response from the vehicle when the accelerator was pressed for 2-3 seconds, then the vehicle suddenly lurched violently forward and hit the rear end of a vehicle in front causing severe damage to the cars.

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.

My name is [xxx], we bought a brand new 2019 Honda Odyssey elite, we have had problems with this vehicle since day one. They have lied and covered up the issues with this vehicle starting with the infotainment center, transmission slippage, fuel pump and the front camera has been overheating giving us the message that it is overheating and all the lights come on. They have stalled us on these issues and now the extended warranty is up and we want something done about this. We have babied this vehicle the entire time since new and it seems like one problem after another, at this point we are very disappointed from the way we are being treated from Honda. The latest is the front sensor on the front mirror that pops up all the lights on the dash, no one seems to be able to duplicate the problem, now they are on all the time and conveniently the extra extended warranty we bought have since expired, there was a lot of recalls on this vehicle and no one ever seems to be able to send us the recall letters. We really thin the mirror sensor and the transmission are definitely safety issues especially when the mirror shuts all the safety off. The transmission shifts hard at times and we pray that Honda will step up to the plate and do the right thing and fix the other recall issues on this same vehicle as well. We have other Honda vehicles that we have not had any issues with, we just can't understand why we are being treated in this manner, we just want the vehicle fixed.

My car slammed on the brakes on its own. I was almost rear ended. I was going 45-50 miles an hour. I think it saw a shadow. Previously it has alerted me to brake because of shadows. This is the first time it braked hard on its own.

While driving at 35 mph a vehicle well ahead of me made a left turn exiting the roadway. My vehicle suddenly applied the brakes even though there was no longer a vehicle in my path. I tried to increase the accelerator, but the vehicle was slow to respond to this. Luckily there was not another car directly behind me. This exact problem had occurred many time previously.

All of the warning lights came on at the same time. The dealer says the internal front camera sensor has malfunctioned and has happened so much that the part is on back order.

On 8. 1. 26, while operating my 2019 Honda Odyssey, the vehicle suffered a catastrophic, un-commanded automatic emergency braking event followed by a total failure of the brake-release fail-safe mechanisms. While driving in active traffic, the vehicle's forward-facing sensor system suffered a false-alarm trigger. Due to a severe design and component vulnerability, the electronic parking brake (epb) switch suffered a simultaneous internal mechanical and electronic hardware failure. Because the epb switch failed internally at the exact moment of the automatic braking event, the system failed to command a brake release. The vehicle’s wheels locked completely, leaving the vehicle completely immobilized in active traffic. This multi-system failure resulted in an immediate, life-threatening crash hazard. By random circumstance and the grace of god, a catastrophic rear-end collision was avoided, but this was a severe near-fatal safety event. A professional automotive diagnostic scan confirmed that the vehicle's computer retained 2 distinct fault incident codes documenting the internal hardware failure of the epb switch. The dealership confirmed that the system provides absolutely no advance warning to the driver, and fails entirely "in the event," meaning the vehicle remains safe until it suddenly and unpredictably locks the brakes on the highway. The vehicle was repaired out-of-pocket for $297 to replace the defective switch. I am filing this complaint because an internal electronic switch failure must never result in an un-commanded, un-releasable wheel lockup while a vehicle is in motion. This indicates a fatal flaw in Honda's braking fail-safe architecture. This issue must be investigated immediately before it results in a future serious or fatal acciden.

Multipurpose camera internal failure disabling my all my safety features in adas.

When I was driving, going about 45 mph, the emergency braking system beeped and breaks were engaged. Not to a complete stop but like a "break tap". Nothing was in front of beside our behind me. It was terrifying and I'm unsure why this happened. Please be advised, this can cause an accident.

Failure of the forward-looking multipurpose camera after a simple battery change. Many safety features are now inoperative including emergency braking, lane keeping assist, adaptive cruise control, among others. Ultimately, a routine maintenance item (battery replacement) is causing the failure of vehicle safety systems.

The dtc u300-49 suddenly failed which affects many of the security systems on the 2019 Honda Odyssey. Upon research, this is very common on the Honda Odyssey caused by it overheating which seems like it should be a dangerous part. It is such an expensive part that we as the consumer have to replace and it should be Honda replacing it if it is their fault that this part fails often. I haven't replaced it as we don't have the funds to replace it, so hopefully it won't pose a safety threat as there are 5 warnings showing on my screen daily.

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.

Drove van about 30 miles and when I cranked it back up. It cranked fine but acc, lkas, auto headlights, and braking system warnings are on. Battery tests fine and camera and emblem is clean and working manner. Not sure whats causing it. Its annoying.

Sensor failed, causing many safety systems to fail - front collision warning, lane keeping assistance, lane departure warning, adaptive cruise control, etc.

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.

Believe camera sensor in windshield or behind Honda emblem causing issues with 2019 ex-l model/ car will pop up 8 different codes ending with "transmission system problem" making vehicle unable to operate. In addition to transmission problem, it also turns off all safety features in vehicle. I have had numerous people complain about this problem as well. Can we please get this recalled and fixed??.

Vans forward collision warning and automatic emergency braking occurred when no vehicle was in-front of the van.

This is a report on a design flaw- not a failed component- in the 2026 Honda Odyssey's "Smart" computer automated safety features, including automatic braking, lane departure, and forward collision warning systems. There have been two types of incidents. These incidents have been repeated on this vehicle dozens of times in our first year of ownership. These incidents are potentially very dangerous because they involve erroneous automatic braking at interstate highway speeds. Unexpected erroneous braking at interstate speeds is a good way to cause a rear-end collision or loss of control. 1. Automatic emergency braking due to erroneous lane departure detection. On interstates in arizona at highway speeds of 65 mph, the vehicle's lane departure detection system throws erroneous warnings when it sees non-lane markings on the roadway, such as tar sealant strips or seams between pavement sections. This has resulted more than once in the vehicle erroneously applying emergency automated braking to slow the vehicle. This happens even when lane assist and adaptive cruise control are turned off by the driver. 2. Erroneous automated braking while overtaking another vehicle. On interstates in arizona at highway speeds of 65 mph, while passing in the left lane a vehicle that is moving much slower in the right lane (e. G. Semi truck climbing a hill at 40 mph), while using adaptive cruise control, automated braking is applied erroneously when there is no risk of a forward collision. The automated braking tends to kick in far earlier than a human driver would brake, and when there is no vehicle in the lane ahead, so it is unexpected and dangerous. This only happens while adaptive cruise control is activated by the driver.

On three separate occasions — may 17, may 20, and may 29, 2026 — the vehicle's automatic emergency braking (aeb) / collision mitigation braking system activated without cause while traveling at highway speed (one of these occasions was on an interstate). On each occasion, no vehicles, pedestrians, or obstructions were present ahead of or around the vehicle. The road was clear. The activation produced a large bright yellow dash notification and the vehicle's brakes activated. Minor children were passengers in the vehicle during these events. The vehicle has an active florida lemon law case with multiple prior documented electrical nonconformities. When I attempted to schedule yet another service appointment to have this defect diagnosed, the dealer, who sold me the vehicle, refused to service the vehicle due to the pending lemon law status and directed me to contact Honda corporate. When I asked the dealer to provide their refusal and the requirement for corporate authorization in writing, they declined to do so. Honda corporate has not responded in over 72 hours. Photo and video evidence of other nonconformities is available.

Forward collision mitigation system displays an error message and does not function. This has been replaced once and continues to fail. The car also turns off at stop lights with the fuel saving automatic restart system, but will not automatically restart.

Cmbs error again now having lane assist error.

The contact owns a 2022 Honda Odyssey. The contact stated that while driving on the highway at approximately 40 mph, the collision mitigation braking system engaged erroneously. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 51,250.

When accelerating from a stop position while pushing on the accelerator the vehicle will not move. Takes a couple seconds. Almost struck by oncoming car when attempting to turn left onto main road. Happens frequently. Next: left sliding passenger door doesn’t close all the way then opens back up. Takes several attempts before it decides to close or with my assistance. Third: rear cargo door shuts without me pushing the button. Alarm sounds and immediately shuts. Been hit in the head once while closing. I’ve seen complaints about this and Honda is apparently aware. Last; the car will inadvertently emergency brake when an oncoming vehicle approaches from the front. Very disturbing when traveling at any speed going into an instant stoppage.

While driving the vehicle under normal conditions, multiple advanced driver assistance and safety systems suddenly became unavailable without warning. The systems affected include automatic emergency braking, forward collision warning, lane keeping assistance, and related safety features that rely on the forward-facing camera. The failures occurred at the same time and were indicated by warning messages displayed on the instrument panel. The vehicle was inspected by an authorized dealer, who confirmed a diagnostic trouble code indicating an internal electronic failure of the forward multipurpose camera. The failed component is installed behind the windshield and is available for inspection upon request. The dealer stated that no accident, physical damage, misuse, or external cause was identified. After the camera failure was identified, the vehicle also briefly displayed a transmission system warning message that later cleared on its own. In addition, the center display screen has shown unstable behavior while driving, including unexpected resets and flashing back to the navigation screen. The sudden loss of collision mitigation, lane assistance, and warning systems reduces the vehicle’s ability to assist in avoiding crashes, particularly in emergency situations, and increases safety risk to the driver, passengers, and others on the road.

My car has started breaking randomly without reason. Just a few days ago it slammed on the brakes. I was driving on the interstate and went around a bend, and my car slammed on the breaks. I. Talking from 70- 5mph in seconds. I didn't have time to do anything. Nothing in front of me, nothing on the side. The car behind me had to swerve into the median to avoid hitting me. My car almost caused an accident. Im honestly afraid to drive it. Im not sure if the radar system is an issue in other Hondas, but if I was in an accident it would have been my fault. If the person behind me wasn't paying attention my children could have been seriously injured or worse. Please look into this issue. Its more dangerous than the other recalls.

I believe the forward facing camera is having electrical issues which is causing the vehicle not to engage lane departure, traction control, lane keeping assistance, emergency braking, adaptive cruise control, ac intermittently blowing warm and cold. There are four or five lights on the dash about this.

Hello I am reporting a safety concern involving a 2022 Honda Odyssey ex-l that was involved in an accident and declared a total loss. During the incident, I was driving in snowy conditions at approximately 50 mph while entering a split lane. The vehicle began to skid, and shortly afterward I observed warning indicators activating. It appeared that vehicle safety systems, including stability or braking systems, engaged automatically. Over the next several seconds, I attempted to regain control by applying the brakes multiple times and making steering corrections. However, the vehicle did not respond as expected. Despite these inputs, the vehicle continued toward the shoulder and ultimately impacted a barrier. I was unable to regain effective steering control during this period. This raises concern about the behavior and response of vehicle safety systems, including abs (anti-lock braking system), vehicle stability assist (vsa), and related driver-assist features during loss-of-traction conditions. Additionally, I became aware of a recall affecting similar model years related to unintended or improper curtain airbag deployment due to system sensitivity. Given that my vehicle falls within this model range, I believe it is important to evaluate whether system behavior may have contributed to the incident. I am requesting that this incident be reviewed as a potential safety issue and considered alongside similar reports to determine whether further investigation is warranted.

I was commuting home, about 30 minutes into the drive, all of the dashboard and radio went blank for a few seconds. It came back on and the break light, anit-collision, lane departure, lights were all flashing. It did this 2 more times in the over the next 5 minutes. I was concerned for my safety because I wasn't sure if my breaks and all the other things were working propoerly. I didn't know how fast I was going or if my car was going to stall on the highway. I see that a recall was issued by Honda yesertday, not for my car model, but a similar issue (a software bug can cause the instrument panel and rear-view camera to go blank). It has not yet been inspected by a repair person. There wre not any warning lights prior to this happening.

The car has started giving warnings every time I turn it on (as of 6 months ago): adaptive cruise control problem, collision mitigation system problem, auto high beam problem, lane keeping assist problem. It seems there must be a fault in the windshield camera that renders all these safety features useless. The repair shop stated that windshield camera isn’t working and is a $2k or more to repair. I am now driving a minivan that doesn’t have many important safety features and this is very dangerous.

The multipurpose camera unit failed causing the forward collision warning, automatic braking, lane keeping assistance, and lane departure warnings lights to come on and rendering all those systems inoperable. Part of the selling point of this vehicle is these additional safety features and for them to fail within 5 years of owning the vehicle is a safety concern. From my own research online, it seems this is a common problem for Odysseys built around this timeframe. This part is extremely expensive and is a required repair if you want the original safety features for the vehicle. I made the repairs, but the life of these units is something that should be looked into.

Adas system, camera behind windshield. Multiple safety systems malfunctioning Honda sense with all adas safety features are not working and risk the emergency braking system to engage without reason. Caliber collison and protech have diagnosed and confirmed the problem. Honda service has confirmed no recall no warranty coverage. Quoted 2500 to fix no prior warning lights or messages. Multiple dash lights occurred suddenly and never went away.
