Automatic Emergency Braking Problems of Honda Odyssey - part 2

Front facing camera went out on a 2020 model. Several warning lights appear related to lane assist, front collision warnings, and automatic emergency braking. These safety features are important, and Honda should issue a recall. The camera is around $800 to replace, plus another $800-$1000 to install and calibrate. Car is only 5 years old, and there have been other camera/electrical related problems, and many recalls. Please hold Honda accountable to fix their declining reliability issues.

The vehicle automatically brakes when approaching a small bridge crossing that had a slight 2 inch lip from pavement to bridge concrete , it also tries to alert of a collision when going around a slight curve when a vehicle is passing .

I was driving my vehicle and accelerating. My vehicle suddenly braked with no warning while I was driving. I hit my left side of my head as I was not expecting this to happen. I was nearly rear-ended/nearly caused a multi car accident. It was incredibly scary to have the cmbs go off for absolutely no reason. There was no car ahead of me or other reason for it to happen.

Multiple warnings regarding adaptive cruise control, lane keep assist, and lane departure warning problems. Honda says it is the front multi-camera. The vehicle works fine intermittently, but doesn’t more often than not. Issue started to occur shortly after a wiring harness recall.

It started that all the sensor in our car started to go off. We were told we had a bad battery, even thought we had replaced it new just last year. Once we had the battery checked and alternator. The sensors started to act up again, out tail gate started to malfunction. Wouldn’t automatically close. A few weeks ago driving down the road the tail gate opened and the anti theft system started going off while the car was running and still going. Come to find out there is a water leak in the rear that has gotten into the rear fuse box and has cause substantial corrosion. The latch to the tail gate is broken. Honda is telling us our extended warranty doesn’t cover any of this, even though it is common knowledge, that the water leak is a known problem from 2018-2021. We just found out a few days ago.

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.

When starting my van, I got warnings for acc, lane departure, and collision mitigation stating that the issues were broken. I received error code u3000-49 at the Honda repair dealer which stated the multipurpose camera no longer works. In doing my research, it appears this is a known issue that Honda is not taking responsibility for and charging $1,500 to $2,000 to repair. They state the car works fine other than having none of those safety features working.

It first started with the power tailgate failure which I brought it to Honda who are aware that there is a faulty sealant that is causing water to get into these Odysseys. They refuse to fix the issues and they are very costly. My van has never been in an accident. Now I'm getting all sorts of warnings from the adas system. Honda has refused to fix their issues and I can not afford $7000 cost to get this cleared up. People who own these vans are complaining and no one is doing enough to get this recalled.

The multifunction forward looking camera in the top of the windshield developed an "internal fault" and either needs replacement or these safety features will fail to work. These safety features allow me to avoid accidents. The problem has been confirmed by the dealer. There are warning lamps that state that these features are no longer working.

__ the present complaint alleges as follows: 1. Honda has a defective design in the advanced driver assistance systems (adas) of all Honda Odysseys, models 2018-2023. 2. Namely, Honda has placed the radar behind the large Honda emblem on the front grille. This causes the radar to give a "radar obstructed" warning, which disables all advanced driver assistance systems in the car (automatic emergency braking, adaptive cruise control, forward collision warning). 3. The "radar obstructed" warning cannot be reset by restarting the vehicle or disconnecting the battery, requiring recalibration of the radar at the cost of $800 each time since it takes several hours to do (per dealership). 4. The official Honda Odyssey forum online has countless complaints on the same issue without resolution by Honda. 5. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering the lives of passengers. 6. Honda has acted in bad-faith towards their customers by designing a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, I. E. , the placement of the radar behind the large, thick plastic h emblem obstructs the radar. 7. I hereby ask that the NHTSA investigate this issue and order Honda to offer a solution in the form of a recall that permanently addresses the problem.

Vehicle start up diagnostics show multiple failures, including abs, e-steering, emergency braking, adaptive speed control. Dealership found a problem with the right rear abs sensor. The sensor wire harness was severed. The harness showed damage in multiple places (see photos). Besides being severed, it showed another deep cut and a place where the outer plastic sheath was cut away. The loss of abs sensor made the vehicle exhibit poor handling including braking. The vehicle has only 4000 miles and is in pristine condition with no damage.

I took my van to the dealer and they told me that the sensor inside of the front mirror is faulty, causing the following lights to continue to cycle if the car is adaptive cruise control problem (acc); auto high-beam problem (a); road departure mitigation system problem; collision mitigation system problem; lane keeping assist problem (lkas); brake system lights. I am unable to engage or disengage any of these systems, including when I am driving. This seems to be a major security hazard and I am aware of others that have experienced this with this exact year, make and model (across different packages) of Honda minivan. I just wanted to report this in case this becomes a major concern for other consumers.

At speed less than 25 mph, the collision mitigation braking system (cmbs) did not work. At cross roads this cmbs will not work when a vehicle comes from the side. This will work only if it detects the vehicle's presence in front for more than 3-5 seconds. Will not activate during sudden presence of vehicle at any speed.

Adaptive cruise control, blind spot monitoring, lane keep assist, automatic braking, auto beam functions stopped working.

After I took my car through a car wash I got the folllowing alert, "radar obstructed warning. " after this warning I then got the warnings for brake system, cruise control all not working.

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.

The front camera has failed for apparently no reason at all. There has been no crash, no damage on our end. We turned the car on and all of the safety warnings came on. The dealership has inspected it and said the code is for the camera failing. Many warning lights appear on the dash due to none of the safety features working without the front camera. This has caused all of the adaptive safety features to fail. There have been no recalls yet, despite the recalls for the rear camera, and many other Odyssey owners having the same issue with the front camera. We have reported it to Honda and were told that it has been reported by others, but not enough times to issue a recall. It is expensive to fix and poses a serious danger to leave due to none of the safety features working. This is a manufacturing defect that Honda is not taking seriously.

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.

For approximately 1 year the collision mitigation braking system will intermittently activate even when no hazards or objects are present in front of the vehicle. This has happened regardless of speed or any other conditions and has even happened while accelerating. There are no lights or warnings that present before the system activates. This poses a hazard of losing control of the vehicle or potential causing a crash due to the unexpected and sudden braking. This problem is intermittent and does not happen every time the car is driving but has happened enough to bring the car in to the service center. The first time we were told they couldn't replicate the problem so they wouldn't look into it. The second time they acknowledged a know issue with their collision mitigation system and recommended the camera and radar be recalibrated at a cost of $850. For some reason this failure of the system is not covered under warranty. They also stated the calibration is not guaranteed to fix the problem.

After a slight rain, the error of radar obstructed is being displayed. Can’t get this error removed or fixed. After searching more I found out that: 1. Honda has a defective design in the advanced driver assistance systems (adas) of all Honda Odysseys, models 2018-2023. 2. Namely, Honda has placed the radar behind the large Honda emblem on the front grille. This causes the radar to give a "radar obstructed" warning, which disables all advanced driver assistance systems in the car (automatic emergency braking, adaptive cruise control, forward collision warning). 3.

Vehicle braking system gets activated too often. Dealership services cannot find anything nor accept there's any issues. Today 08/15/2024 the vehicle locked up the brakes, while driving at 55 mph; injuring a 15 yr; 12 yr; 11yr; and 57 yr. Grandmother. Called dealership services and stated they will see vehicle, but don't believe to find anything, as before. Two of my family members sustained neck injuries. Can you please help. Vehicle can be inspected anytime. Please call first.

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 just started up the car one morning and had multiple sensor warnings. Brought it to the Honda dealership and told it was an internal sensor camera malfunction and wanted $2000+ to fix it. This honestly should be a recall as I’ve had several other Honda owners complaining about the same thing which is a huge safety concern.

While driving in the through lane, we experienced (this has happened several times) a sudden sharp braking due to a car in a turn lane being stopped and sensed by the anticollision system. We believe this same system has caused hard braking when changing from a through lane to a right turn lane without putting on the turn signal. It also "gently" brakes at times when the lane markings on one side or the other are faint or missing, we think the system sees this as a lane departure. The most recent sharp sudden braking almost caused us to be rear-ended. Along with this there are various issues with proximity sensors around the vehicle. We believe all of these issues are related.

On a number of occasions the automatic braking system has engaged when no vehicles or objects were present in the vicinity of the vehicle. This is incredibly dangerous. When I get in the car now I have to remember to disengage that feature before operating the vehicle.

It’s starting raining and the brake system light came on and hasn’t went off.

Started the car one morning and instantly a bunch of warning messages appear on the dashboard stating; 1) collision mitigation system problem 2) lane keeping assist problem 3) road departure mitigation system problem 4) auto high beam problem 5) auto emergency braking problem. There is also a brake system light on now (amber color) due to the above. Never had an issue before now. This is on a Honda Odyssey 2019 ex with just over 35k miles. Took car to local mechanic who ran diagnostic report and found the following issue; "integrated driver support/monocular camera driver support system issue; multi-purpose camera unit/millimeter wave radar internal electronic failure" contacted the Honda dealership who want $1500 for a new device and programing; this is disgusting. This issue is so widespread its almost ready to be a full blown recall.

With low reproducibility rate, the vehicle may activate alarms or emergency breaking in response to wide open lane with no obstructions. What component or system failed or malfunctioned, and is it available for inspection upon request? automatic emergency breaking / radar how was your safety or the safety of others put at risk? unexpected change of behavior has the problem been reproduced or confirmed by a dealer or independent service center? no has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no except during the event.

The multipurpose camera above the rearview mirror has stopped working. It controls several systems including; adaptive cruise control, automatic brake system, forward collision warning, lane keeping assistance, lane departure warning, automatic high beam control. Every time I start the vehicle I have to clear 6 different malfunction warnings and non of the effected systems will function. There is an increased risk of accidents. I just had a vehicle diagnostic ran at flow Honda of charlottesville va and they quoted me a price of $2,060 to replace the part.

One day my car just turned on. Lights come on will not turn off. Dashboard lights up with every symbol blinking, relays under the hood turning off turning on non-stop. Took it to the Honda dealer, who said I needed a vsa module. Only catch here is the part will not be available until October 2024. 4 months from now. Was told they put me at the bottom of the list as my car is 7 years old. Newer vehicles get priority. Rich people first poor people last. When it would run car would randomly just turn off while driving. Car unsafe to operate.

I was driving, and there was a car coming from the opposite direction in their own lane, and nowhere near my car, and the automatic braking slammed on the brakes. This was just the worst instance of it malfunctioing.

The camera that controls all the advanced driver assistance system fails intermittently. This causes 5 different warnings to come on and all of the safety features bases on this camera to stop working. This is an ongoing issue. An internet search shows that there are multiple Honda vehicles with this problem.
