Automatic Emergency Braking problems of the 2018 Honda Odyssey

We turned the car on and got an acc, lkas, fcs, ahl errors due to the front sensor and the camera failing. This is an issue that many Honda owners are dealing with. The issue will not allow you to use cruise control and will disable 90% of the safety features we bought this vehicle for. The car drives fine but the safety of those in the car is affected by this error and needs to be recalled due to the number of complaints of this issue. There were no errors or warning signs prior to this happening.

Suddenly one day in the morning taking my car from my garage, all alarms in my board turned on and stopped working: automatic emergency braking, blind spot warning, forward and collision warning, lane departure warning, lane keeping assistance and rear cross traffic warning. I bring my car to the mclarty Honda service in little rock, ar. After calibration showed that I need a new multipurpose camera code u 3000-49. This is major concern for me. My van is in perfect shape, only 7 years old not so many miles. Doing some research sounds like this is an issue with Honda vehicles. My neighborhood is full of kids ( I have 3 kids too)with these large vehicles you can find a lot of blinds spots and these features help to keep everybody safe. I believe this a safety issue that need to be recalled in Honda's cars.

The windshield monocular camera failed, disabling all safety precautions.

Automatic emergency braking, forward collision warning, and lane departure warning systems stopped working simultaneously without warning. Upon further investigation, failure of the forward-facing camera is the likely root cause. Based on conversations in internet discussion forums [xxx] , [xxx] ), this is a common failure. There was a recall for the Odyssey to fix a wiring harness issue that could affect the back-up camera. I believe loss of the automatic emergency braking, forward collision warning, and lane departure warning systems is much more serious, with potentially catastrophic consequences. Since evidence suggests failure of the forward-facing camera happens frequently, I believe this issue should be treated with the same gravity as the back-up camera and a recall should be issued.

I was involved in an accident with with my family. Pregnant wife and daughter. I got into a front end collision and I was at fault. The forward collision warning didn’t activate, neither did the automatic emergency braking. This system has never failed on me and car has always stopped every time. .

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.

On September 1, 2025 the front windshield camera on my 2018 Honda Odyssey failed, part #36160-thr-a03-m1, resulting in the loss of many of my vehicle’s safety features including: adaptive cruise control, emergency braking, forward collision warning, lane departure warning and lane keep assistance. The camera is available for inspection. Now when I start the vehicle it displays warnings that none of the above safety features are functional. I contacted 2 local Honda dealers, bellingham Honda and burlington Honda in washington state. Both dealers said they could not fix my car since the camera is not available, since it is not in stock and on national back order, with no date of when a new camera would be be available. I have also contacted 2 online Honda parts distributors and they also say the camera is in national back order and not available, with no date of when it would be available. The result is that my vehicle has most of it’s safety systems inoperable and it can not be repaired, since a new camera is not available, and Honda cannot provide me a date when the part is available and my vehicle can be fixed. I see on the internet the front camera failure is a common occurrence in 2018 Honda Odyssey’s and request NHTSA investigate make Honda recall these vehicles to fix the safety problem.

The automatic braking system beeped alert then applied brakes when I was going around a sharp curve, with cars behind me. Luckily they were far enough behind that they didn't hit me. This has been happening since I first got my Odyssey. I asked the Honda dealer about it if it was a defect and they said no that's how it work. I asked if I could turn it off permanently and they said no - I had to turn if off each time I turned on the car. Which I do most times but I forgot yesterday. I started turning it off regularly when it slammed on the brakes going around a curve some time ago bringing me to almost complete stop with car behind me. I probably should have reported earlier. I was in the car with a friend yesterday when it happened and she has a different model Honda and says it happens to her as well. I also am in a Odyssey facebook forum and someone with a 23 Odyssey is experiencing it - I thought perhaps it was my year and they'd work out the kinks but it does not appear so. I was willing to give Honda a little grace on these early safety systems, but this looks to be an ongoing problem which is unacceptable. I'm going to look into a dashcam to record these incicdents. I asked the dealer because surely they would be able to see a log of when they automatic braking engaged? if not, they should.

1. Vehicle information year / make / model: 2018 Honda Odyssey touring mileage at time of incident: approximately 123,952 miles purchased new or used: used 2. Incident summary on June?13,?2025 upon starting the vehicle for the first time that day (vehicle is garage kept, year round, at home when not in use), problem codes for the auto high beam, adaptive cruise control (acc), lane keeping assist system (lkas), collision mitigation braking system (cmbs), and road departure mitigation (rdm) showed on the display and all features failed to function. 3. Detailed description of failure & safety risk (chronological) component/system affected: I have not taken the vehicle to the local Honda dealership as yet as I plan to schedule an appointment during the week of 17 August. After researching this issues it is found that many other consumers have experienced the same issue and confirmed that it was the adas front-facing camera and radar sensor failure. Due to the failure this causes the following safety systems to cease functionality: auto high beam, acc, lkas, cmbs, and rdm. Vehicle is available for inspection upon request. Safety risk: all affected systems are critical for maintaining lane position, speed, collision avoidance, and visibility. Not having these critical safety features creates a heightened risk of collision or unsafe maneuver. Inspection: only an authorized Honda dealer will inspect/diagnose the issue. There has been no inspection from the vehicle manufacturer, law enforcement, insurance, or independent service.

My car have never in an any accident but my distance radar sensor not working. And it’s very risky to drive under this condition and it’s very big safety for me and my life so help me to fix this issue.

The multipurpose camera failed bring down all driver assistance functionality including lane keep assist, emergency brake, auto high beam, parking sensors, cruise control, etc. Fix is outrageously high $2500+. Internet search finds this to be a very common issue and deserves a recall.

The windshield monocular camera is completely non functional causing several dashboard errors to appear. It very disheartening as this is such a known issue within the Honda Odyssey community and very expensive to replace and get calibrated after replacement. This should be recalled since so many are having this issue. Clearly this is a fault of Honda. It seems that the camera can get too hot being in the windshield and just doesn't work. A big reason why I wanted this vehicle was because of these sensors. Now I can't use them.

Front facing camera malfunctioning, and it is available for inspection upon request. This malfunction causing 5 different warning lights to show up on dashboard. Including 1. ) auto high beam problem, lane keeping assist problem, collision mitigation system problem, adaptive cruise control problem, road departure mitigation problem. The issue has been confirmed by the dealer. There were no warning lights prior to the random malfunction. I have not had wind shield replaced (which I have read could mean a calibration of the camera issue), nor has there been any accidents taken place. My safety is at risk as I am unable to use these features while driving unless the front camera is replaced.

Multipurpose camera failure. Warnings appeared upon failure after being parked in the shade on a moderately warm day ~80 degrees. Warnings with chimes reappear after being cleared, causing distraction while driving. Safety systems are inoperable without expensive camera replacement. Systems disabled as a result include adaptive cruise control, collision mitigation system, lane keeping assist, road departure mitigation, auto high beam system.

Several warnings popped up on my dash at once: adaptive cruise control, lane keep assist, brake system, auto highbeam, collision mitigation system, and road departure mitigation system. The dealer’s internet is down for at least several days, so they are not able to troubleshoot the problem. However, an internet search to troubleshoot myself indicates that this is a standing, systemic issue with 2018 and 2019 Honda Odyssey’s that may warrant a recall.

Prior to purchasing this vehicle, on the test drive, the vehicle slammed on the brakes for no good reason. The dealer assured me the collision mitigation braking system (“cmbs”) can be turned off, so I bought the car. I then learned that the cmbs automatically turns on every time the engine is turned on. I must shut cmbs off each and every time I start the car, but since my other car is a Tesla (which doesn’t have this problem), sometimes I do forget to shut off cmbs. Through out my almost 7 years of ownership, the car has slammed on the brakes countless numbers of times for absolutely no reason at all. Sometimes no cars are behind me, but there have been several times when cars behind me have almost crashed into me due to my faulty cmbs. My elderly mother is in need of a car and I refuse to let her borrow mine because I am scared she will forget to disable the cmbs and get into a crash. I am deeply astonished that with everything that is known about Honda’s cmbs, NHTSA has not taken any action against this dangerous feature. I wonder what NHTSA is getting paid to look the other way. A complete failure of an institution I used to hold in high regard.

I started the vehicle and it displayed a message on the infotainment system screen that the system had lost power. I believed that this would only affect the radio functionality which I was not concerned about immediately. I placed the vehicle in reverse and I accidentally backed up into a parked car. At no point before the accident did I realize the rear camera did not work and the collision assistance sensors did not function. I believe if the collision avoidance system was working correctly my accident would have been prevented. I have come to depend on the safety features of this vehicle. I know that this is not an issue with my car battery as I recently had a Honda dealer install a new battery prior to this accident and the vehicle started normally.

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.

Warning messages for the following appeared: brake system lane keeping/assist system collision mitigation system problem road departure mitigation system problem auto-high beam problem adaptive cruise control problem none of these safety features now work. Our local dealership told us it was a failure of the multipurpose camera unit. The fix we are told is a $1400 part. The rear camera was just recalled by Honda and repaired within the last month. This failure should not have happened and greatly impacts the safety of the car and it is a common problem when searching Honda message boards.

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.

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.

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 automatic emergency braking system (aeb) the collision mitigation braking system or “cmbs. ” ingaged and stopped the van four (4) times when there where no obsticals in front of the van. Twice this happend while making left turns in four-way intersection.

Honda has a recall notice to repair the rear camera. We took the car in to get the recall service. The camera stopped working. Honda told us the diagnostic to determine what wasn't working on the camera would cost hundreds of dollars. This was recall service that disabled the camera. We should not be charged and they have messed up our car system.

2018 Honda Odyssey - 120,738 miles at time of occurrence premature failure of the monocular camera (Honda part number 36160-thr-a04). This impacted adaptive cruise control, automatic breaking, forward collision warning, lane departure warning, lane keep assistance and automatic high beams. This part failed very suddenly when I was on a major highway. No warning lamps prior to failure we kept the part for inspection. The problem was confirmed by a Honda dealer and the part was replaced at my expense ($1,335. 88). Reported to american Honda who told me this was no longer under warranty. When I tried to find the part myself, it was on a long back order and I was told by many other dealers that this is a common failure.

While attempting to cross a road the vehicle suddenly stopped accelerating. This happened after entering the roadway with heavy traffic and my family in the vehicle, I pressed the accelerator pedal all the way down nothing. Then after a brief 5sec of fear the vehicle jerks into gear making everyone slam back into their seats. This has been reported by many owners on various forums, some of which were in accidents. This will not end well for a few drivers and their families. Honda technicians try and diagnosing this with no luck, said” I’ve never seen this issue, 64k miles great condition no damages to the transmission core unfortunately we are 4k miles over warranty!? at here is a recall for very similar issues same vf 9 speed transmission but my VIN didn’t fall under the recall, american Honda said they weren’t going to help because I didn’t have “customer loyalty” I’m asking the technician to dissemble the transmission and take a bunch of pictures to try and help explain how this happened and how to avoid this from happening again because next time we may not be so luck.

The automatic emergency braking system has failed multiple times. The vehicle is available for inspection. My safety and the safety of others are put at risk when my vehicle executes unexpected emergency braking. The problem has been reproduced and confirmed by the dealer on two different occasions. The vehicle has not been inspected by the manufacturer, police, insurance representatives of other, except the Honda dealer. No other warning lamps, messages of other symptoms. Around Feb 1, 2019 the car started applying the brakes when crossing slightly raised railroad tracks. The braking action was hard enough to engage the antilock brake feature. On 2/11/19 the vehicle was taken to autowest Honda for warranty repairs at 22,853 miles. The millimeter radar was mis-aimed. This corrected the problem. See attached repair order. On 9/21/20 while driving on the freeway at approximately 65 miles per hour the automatic emergency braking system activated as I passed a vehicle on the right. There were no vehicles in front of me. Braking was again hard enough to activate the anti lock brake system. The vehicle behind me just taped my car. Only a tiny nick was put in my bumper. On 9/22/20 I returned the vehicle to autowest Honda. The car had 47,655 miles on the odometer. It was found that the millimeter radar was mis-aligned again. It was realigned free of charge and all was well for the next 22,000 or so miles. On or about 8/25/22, with approximately 66,000 miles on the odometer the automatic emergency braking system activated at about 65 miles per hour as I was passing a vehicle on the right. Again the anti lock braking system activated. The vehicle behind me did not hit my vehicle, but was apparently hit from behind as I saw at least one vehicle run off into the ditch as I looked in my rearview mirror. I believe this to be a design defect in the vehicle the mis-alignment of the millimeter radar appears to be an ongoing problem about every 22,000 miles.

I have the car in service for the second time related to errors and issues around adaptive cruise control, automatic breaking, and collision assist. On a couple occasions the auto braking system engages when there is no need.

Four years ago I bought this vehicle, immediately from day one, up until today, the automatic braking system slams on the brake randomly for no reason, sometimes even on highways. I contacted Honda several times and they offered no fix to this. Since the first week of owning the car, up by until today, I need to disable this feature each and every time I start the car. The few times I forget, the sudden braking reminds me. I am shocked NHTSA has not investigated this.
