Service Brakes Problems of Honda Odyssey - part 1

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. .

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.

Normal speed of 25mph on a clear warm day with no road obstructions when the brake system indicator (red) illuminated. I pressed on the brake and had severe resistance and was barely able to stop the car. Two more indicators illuminated. One I believe was the vehicle stability assist and the other I don't recall. The screen flashed "call your dealer". The owners manual states "have your vehicle repaired immediately. " the vehicle was hauled to southeast Honda. Codes uo416-680416-f8, u0418-68, u3000-49i. The brake booster was replaced. I am concerned that an in-experienced driver traveling at interstate speeds might have a fatal issue.

While driving approximately 40 mph, the vehicles emergency avoidance system activated and applied the brakes very heavily. We were nearly hit by a vehicle behind us, which nearly caused multiple accidents. There was nothing in front of us, and the road was CO. Pletely clear in front of us.

The powertrain jumps sometimes it is not smooth. The brakes does not hold too good.

My car unexpectedly did a phantom brake at high 60+ mph with no car in front of me. I was so nervous due to car behind me almost colliding into me.

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 contact owns a 2019 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the abs warning light illuminated. In addition, the contact stated that several unknown warning lights were also illuminated. The vehicle was taken to the dealer, where it was diagnosed with a failed camera system. The contact was informed that the camera system needed to be replaced, and the software needed to be updated. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 87,395.

Collision mitigation braking system (cmbs) my 2019 Honda Odyssey slammed on the brakes while traveling 70+ mph on a clear freeway. There was no warning and nothing in the road. I have also had issues with the braking warning light flashing for no reason while traveling down the roadway. I called the Honda dealership and inquired about the braking issues and was told unfortunately it can happen, especially if I drive on windy roads.

While driving, the battery indicator light illuminated. Suddenly, the power turned off. The vehicle could be steered and brakes used, only. Then, as quickly as the power turned off, it restored and momentarily powered the accelerator. Then the power stopped again. The lights within the cabin and on the dash flickered and chimed like they were possessed. Then nothing. When the power would flicker on, the engine/transmission would "catch" and jerk the vehicle. Fortunately, I coasted to my residence without an auto accident. I reported this issue to williamsburg Honda who will address the issue tomorrow when the vehicle is towed there. I was at risk along with my two school-aged children for a deadly auto accident since the power to the vehicle was lost. I have to use another vehicle and am uncertain of my trust for the van with myself and my family after this terrifying incident.

At restaurant on 6/1/25, backed out of parking spot. Drove about 30 ft to parking lot exit. Turned onto side street to go to light and turn on main street. About 3 or 4 car lengths from exit to light. Side street sloped down about 20-30 degrees. Brakes would not stop van. Not sure if brakes slowed down van as going slow. However, brake pedal pushed hard down to floor but did not stop van. If hit gas pedal van would have accelerated and engine raced causing acceleration and more damage. No damage to back of vehicle I hit. Very minor damage to my van. Tried yesterday and today to replicate (in isolated locations and with no other vehicle near) the van’s conditions at time of incident. I will be contacting dealer. There is no recall. Do not know if anyone else had this problem or if dealer can find any issue. Notifying NHTSA to advise of this potential systemic issue. I’ll follow up with results of interaction with dealer.

The contact owns a 2007 Honda Odyssey. The contact stated while driving 45-65 mph, the vehicle stalled. The contact pulled over to the side of the road and waited for two hours. The contact then continued driving 20-25 mph. The contact stated that the vsa (vehicle stability assist) and tpms warning lights were illuminated. The vehicle was taken to auto zone, where it was diagnosed with battery voltage, brake sensor, ecm and pcm failures. The dealer and the manufacturer were not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 238,133.

About 5 warning lights came on simultaneously keeping me from driving my vehicle safely.

Vehicle make/model/year: 2022 Honda Odyssey date of incident: 5-1-25 mileage at incident: 30,000 summary of incident: while my 2022 Honda Odyssey was fully stopped in traffic with my foot firmly on the brake pedal, the vehicle unexpectedly lurched forward and struck the car in front of me. Just before or during the lurch, the brake system warning light appeared on the dashboard. I did not have my foot on the accelerator at any time. The road was flat and weather conditions were normal. The idle stop system has not been functioning for several months, so the vehicle was operating in normal engine-on mode. Despite this, the car surged forward from a full stop, indicating a possible failure in the brake system, electronic throttle control, or a software/ecu malfunction. This was a dangerous, uncommanded movement of the vehicle while stopped, which resulted in a minor collision. Thankfully, no one was injured, but this poses a serious safety hazard, especially if it were to occur in crosswalks or at intersections. I will report the issue to Honda the dealership and requested a full diagnostic inspection. I am submitting this complaint because this incident could have caused serious injury or worse and may be part of a broader defect affecting brake or throttle systems on this model.

The contact owns a 2024 Honda Odyssey. The contact stated that while driving at 60 mph, the brake pedal was inadvertently applied without driver input. There was no warning light illuminated. The vehicle was taken to several dealers however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 2,997.

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.

The contact owns a 2019 Honda Odyssey. The contact stated that upon starting the vehicle, the messages "emissions system failure", "brake system failure", "brake hose system failure", "power steering failure", "eps failure, "vehicle stability assist (vsa) failure", "hill start assist failure" and "road departure mitigation system failure" were displayed. The vehicle was taken to the dealer, where it was diagnosed that the fuel injectors had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure and a case was filed. The manufacturer referred the contact to the NHTSA hotline to file a vehicle safety complaint. The failure mileage was approximately 120,000.

The failure mileage was approximately 120,000.

The front camera has failed resulting in safety concerns including braking system and cruise control failure. This is a known issue with many new Honda Odysseys and needs to be recalled as it is not safe to drive as it disables all Honda sensing and auto braking components on the vehicle.

Multiple warnings occurred simultaneously for the "brake system" intermittent. I have the same issue per [xxx] for my Honda Odyssey 2018 elite. I can see the same problem by a lot of people. I told Honda and paid them $220 diagnosis fees and they ended up asked me to change the whole camera that cost 4k. This obviously defect issue from Honda. Looks like known issue for this. Can this escalate back to Honda? for example [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

A number of warnings popped adaptive cruise control problem, lane keeping assist problem, collision mitigation system problem, road departure mitigation problem, and auto high beam problem. Only light that is on is my brake system light. I read a bit on some forums and it is likely to be the the front camera. Apparently the multipurpose camera unit (mcu) fails often on these vehicles, causing these errors and the cruise control to stop working.

All the symbols related adas suddenly popped in my car with no rain or snow or any accidents. When I checked with Honda dealership, they said it caused due to software issue and nothing related hardware and it needed 2500$ for replacing the entire system. If it is software causing this issue why would customer had to pay for it, and it could be a recall. I noticed similar issue for all 2019 and above models.

Radar structed ,blind spot off,brake system light on.

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.

Car was operating fine on the way to a game on 11/25/2024. Parked and went inside to watch game. After the game I went to my car and when I cranked it all the warnings below came on. **auto high beam problem * problem **brake system problem **lkas problem those are the warnings I can remember. I immediately cut the car off and walked around to see if maybe I had been hit while parked cause something told me it could be a camera issue with the lkas problem ???????. I had not been hit. The car was fine and just as it was when I parked it. I cranked it again and the lights were still on showing problems and stayed on. I took it to the dealership and they said it's the multi-purpose camera malfunction/went out and needs new one.

I was traveling on a local street around 35mph and braking for a red light. The braking felt funny in that it didn't slow the car down like normal, but it felt like the car's accelerator was still engaged. I managed to come to a stop, but the car seemed to want to move forward and I had to really stomp on the brake to keep it from moving forward. I put the car into park and the engine started revving and the car started shaking. I then turned the car off. When I turned the car back on, I was not able to shift back into drive from park. I turned the car off again. Waited about 10 seconds and started the car again. I was able to put it into drive and was able to drive home. This was normal braking for a red light, not a panic brake when I might have hit the accelerator. I also check the pedal positions and when the brake is pressed, it is about level with the accelerator, so I doubt that I was pressing both pedals at the same time. I don't have an extra floor mat and the mat I have is an oem mat that is secured down. Brought the car to a Honda service center and they could not reproduce the problem. This is certainly a safety issue if the braking and engine do not respond to the driver input.

We have taken our 2013 Honda Odyssey several times to the shop because the brakes don’t feel safe. They seem to work fine but the brakes pedal is spongy. Keeping the brake pedal slightly pressed with the engine running, the pedal continues to sink almost to the floor. So far we have spent over $1000 for a new brake booster, new master cylinder, brake fluid flush and brake bleeding. The shop bled the brakes several times, manual and computer bleeding but the brakes are still spongy.

This is the second time I’ve had to bring my car in. I have a variety of different warning signs popping up and I see that I’m not the only person that this is happened to when I look at reddit online the malfunction is somewhere within the car system and it’s because of a windshield camera, which has nothing to do with the, warning signs that I am getting on my car. This needs to be recalled and fixed for free.

The contact owns a 2007 Honda Odyssey. The contact stated that while operating the vehicle a burning chemical odor was present coming from the engine compartment. Upon inspection it was discovered that the brake fluid reservoir was empty. The brake fluid reservoir was refilled but later the contact discovered that the brake fluid reservoir had quicky emptied but no visible signs of a brake fluid leak was present. The cause of the failure was not determined. The manufacturer and local dealer were not contacted. The failure mileage was 205,000.

The whole adas system went down and a brake system light came on. Van isn’t in warranty but isn’t old either. Just out of warranty. Lots of safety items disabled because of a faulty camera that’s too expensive to replace on our own, so now we operate a Mini-van without all the extra safety items that adas gives you. Guess adas was never intended to improve safety if it only works for a couple of years.

The front facing monocular camera of the adas system has failed on this 2019 Honda Odyssey with approximately 50,000 miles. The failure of this camera has rendered the adas systems inoperable including adaptive cruise control, automatic emergency braking, forward collision warning, lane departure warning, and lane keeping assistance. This appears to be a common complaint/failure mode amongst many similar Honda models 2018 - 2022.

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.

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.

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.

This car continues to slam on the automatic brakes when there is no obstruction. There is no car in front of me today. It almost caused a major accident.
