Service Brakes Problems of Honda Odyssey - part 1

2025 Honda Odyssey with 21. 5k miles. Noticed the van shaking when braking. Took it to the dealer for warranty service and they claim that warped rotors were the issue. Declined to provide warranty service claiming brakes are only covered for 12 months. Rotors should not be warped after 20k miles, especially when never used under heavy load.

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.

I have experienced numerous instances where my car will stall at a stop light and then fail to restart, even with switching gears to park before resuming to drive. . I have had to turn on and off the engine multiple times at a si hole stoplight before the car would resume movement. This scenario has now happened at least 3 times. I am a mom driving a minivan of kids and this is concerning for our safety. These are not long stop lights. Sometimes even at a stop light I feel a strange pulling sensation.

When I stop at the red light with my brake pressed, all in a sudden the brake drop lower and the vehicle move forward. When I look up the safety recalls on my type of vehicle, there is a brake master cylinder safety recall in 2010. However, when I look up my VIN, my vehicle is not on that list. Based on the problem, it looks like my batch of Odyssey also has this safety recall issue. Probably Honda hide it to minimize the recall repair cost. I am the first owner and the brake master cylinder has never been replaced and no recall notice is being sent to me. Please help to investigate it. I will pay out of pocket to fix this issue first because I almost died with this hidden uninformed safety issue until the problem comes up now.

On 7/28/26, my 2018 Honda Odyssey began displaying the following warning lights and system messages on the dash: •adaptive cruise control (acc) system error •lane keeping assist system (lkas) error •auto high beam system error •collision mitigation braking system / forward collision error these errors were present before I replaced the 12v battery. I had the battery tested at that time and it failed a load test, so I replaced it, expecting the adas-related errors to resolve. After the battery replacement, the original errors remained, and additional warning lights appeared, including a transmission system problem indicator and a brake system warning light. I disconnected the negative battery terminal for approximately 10 minutes in an attempt to reset the modules, then reconnected it. After reconnection and a period of idling, further warning lights appeared that had not been present immediately after the battery swap. I have not been in a collision, and there was no impact to the windshield, front bumper, or brake components at any point during this period. The vehicle’s brake pedal feel has remained normal. Because these errors were present before the battery was replaced, the battery does not appear to be the root cause, and the underlying issue affecting the acc, lkas, auto high beam, and collision mitigation systems remains unresolved. I have seen reports from other Honda owners describing similar cascading adas and system warning lights on comparable Honda models.

When stopped at a red light today, our minivan's auto idle stop (ais) system stopped the engine with the brakes depressed (as advertised). Once the light turned green, the driver released the brake to re-engage the motor, but the starter did no restart the minivan and a battery light flashed on. The start button had to be pressed several (~4) times to get the motor to restart and to turn the battery light off.

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.

The incident is that the rear brakes keep wearing much faster than the front. New brake pads do not last after only less then 10,000 miles of driving. Dealership and mechanic expect that there is a caliber issue with the 2019 model that is causing the rear brakes to wear too fast. Manufacturer should remedy this issue.

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. . .

Brake lights completely out and almost caused a major accident.

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

Stopped at light. Car turned off per the start/ stop feature. Removed foot from brake and pressed gas pedal, car started but brake light came on and continued to flash. Had to pull over and stop before light would stop flashing and go away.

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.

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

The vehicle was in reverse and started to accelerate uncontrollably in reverse. The car came to a stop after hitting a wall and a car. The uncontrolled acceleration happened when we went about 1 foot onto grass while in reverse. The emissions light was going on and off from time to time. We believe it was inspected by a Honda dealership at some point. The vehicle is involved with insurance at this point.

On April 13, 2026, I brought my 2019 Honda Odyssey to a Honda dealership in chicago, IL for a dealer-initiated recall service. The dealer contacted me and asked me to come in. Before the recall service, the vehicle had zero warning lights, zero error codes, and was operating completely normally. Immediately after the recall service was completed, the following warning lights appeared on the dashboard: brake system warning, hill start assist problem, vsa (vehicle stability assist) warning, and additional stability/steering system warnings. None of these warnings existed before the service. I returned to the dealership the same day. The service team cleared all error codes. However, within minutes of driving off the lot, all warning lights reappeared. This confirms the issue is persistent and not a one-time post-update self-check. I returned a second time. The service manager stated the warnings were not caused by the recall service and refused to investigate further. The dealer quoted $800 for diagnostic work. I also contacted american Honda by phone and was told they could not intervene. With the brake system and vsa warnings active, the anti-lock braking system and vehicle stability control may not be functioning properly. This puts me and other drivers at risk, especially in emergency braking situations and on slippery roads. This pattern of multiple safety warnings appearing immediately after recall service on 2019 Honda Odysseys has been reported by other owners. The vehicle and its warning lights are available for inspection upon request.

When driving the ac will turn down by itself and when coming to a complete stop the car will put itself in park and the engine will shut off completely. The brake light and engine and battery light will come and the car will restart itself and stay in park or I will sometimes have to restart the car myself. The brake light started to flash on 4/16/2026. I purchased the car on 12/18/2025 to finance . The vehicle will slow down and jerk back and forth when driving at a normal speed .

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!.

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.

Multiple safety systems on my 2019 Honda Odyssey elite have simultaneously failed, including lkas, acc, collision mitigation braking system, auto high-beam headlights, and other driver-assist features. The dashboard displays warnings for nearly every safety-related system, and the vehicle disables these features without warning. **detailed description of the problem:** whenever I start my vehicle, multiple error messages are displayed related to the lane keeping assist system (lkas), adaptive cruise control (acc), collision mitigation braking system (cmbs), road departure mitigation, auto headlights, and other safety features. These warnings appear together and persist even after restarting the vehicle. Apparently, this issue is widespread among 2018–2020 Honda Odyssey owners, with many reporting the same cluster of system failures. The problem appears to be related to a malfunction in the vehicle’s electrical system, sensors/ cameras, or control modules. In my case, the failures occur without any external damage, weather event, or driver action that would explain the sudden loss of safety functionality. When these systems fail, the vehicle disables critical safety features such as automatic emergency braking, lane keeping, adaptive cruise control, and automatic headlights. This creates a significant safety risk, especially at highway speeds or in low?visibility conditions. **frequency:** the issue occurs whenever the vehicle is started, affecting my driving everyday.

What happened? while driving my 2025 Honda Odyssey, the engine failed to restart during an auto idle stop event at a 4-way stop/intersection. When releasing the brake to take my right-of-way, the engine stalled completely. The vehicle became immobilized, the power steering went heavy/stiff, and the brake pedal became difficult to depress. I had to manually cycle the ignition by shifting to "park" and pressing the "start" button multiple times to regain power while traffic was waiting. This has occurred twice. What component or system failed or malfunctioned? the auto idle stop (ais) system and the starter/charging system. A service technician recently documented a "slow crank" during routine maintenance, suggesting the battery is unable to handle the restart load. How was your safety or the safety of others put at risk? the vehicle stalled during a right-of-way transition (green light/4-way stop). This created an immediate risk. The loss of power steering and the stiffened brake pedal could have made the vehicle nearly impossible to maneuver manually on an incline during the failure. Has the problem been reproduced or confirmed? a dealership technician confirmed a "slow crank" symptom during a multi-point inspection, though they could not reproduce an issue. The battery tested good. Were there any warning lamps or symptoms before failure? yes. A "slow crank" was noted by a technician when attempting to start my vehicle to check my vehicle mileage. During the stall itself, a red exclamation point warning appeared on the dashboard.

Florida miss firing lights on.

Receiving acc, lane keep assist, front collision , auto high beam errors on the instrument screen. None of the safety features work. Cruise control does not work.

While brake pedal depressed and car coming to a stop at a traffic light, car surged forward as engine revved and hit another car in front of it. Brake pedal was depressed the entire time.

I have a 2021 Honda Odyssey ,40k miles, some lights on about few months ago, then I went to dealer on June 29,2026. I paid for a dealer diagnoses, they told me is the vsa modulator faulty. I don't believe that is over 36k miles warranty , so I search it on google, shows Honda had some recall on different model and year car with the vsa modulator, so I think we must check it ,if on Odyssey need recall it too.

Multiple system problems constantly on my dashboard. Has brand new spark plugs and battery and problem is still there.

Multiple warning lights, all for the safety system: acc, automatic emergency braking, etc. I am told by the dealer that this is due to a faulty forward camera. Looking at the NHTSA site and other forums, this is a very common issue and should be addressed.

The vehicle experiences abnormal vibration and shaking felt from the rear during braking at moderate to highway speeds. The condition does not occur during steady driving and is isolated to braking events. An authorized dealership inspected the vehicle and documented rear brake rotor thickness variation but no repair was performed. The issue has continued and raises concerns about braking stability and safety, especially at higher speeds.

On December 31 at approximately 300 p. M. , our 2015 Honda Odyssey experienced a sudden and complete loss of motive power while traveling eastbound on the sam houston parkway south just after crossing the buffalo bayou toll bridge at highway speed. While driving normally, the check abs warning light illuminated. Immediately afterward, multiple dashboard warning lights began flashing and the engine abruptly shut down with no warning. The vehicle lost all ability to accelerate and became disabled in active traffic lanes. Steering and braking were severely affected due to the sudden loss of power. Hazard lights were activated while the driver attempted to move the vehicle from the middle lane to the shoulder. We narrowly avoided a collision and were able to stop near the pine avenue on-ramp. Once stopped, the vehicle completely shut off and would not restart. All vehicle systems appeared inoperative except for the hazard lights, indicating a possible electrical system failure. Emergency services were required due to the dangerous location. The vehicle was occupied by five people, including three children. The sudden loss of motive power at highway speed created an extreme safety hazard and could have resulted in serious injury or fatality.

I took this car for a test drive. The dealer said they had repaired a number of issues such as front end work, power steering hoses, and power steering fluid. They said it had passed a safety inspection. The dealer handed me a list of all the issues with the vehicle which they chose not to repair, which include: 1) vehicle driver door lock/unlock doesn't work 2) driver sliding door doesn't work 3) beeping when turning on power sliding doors (doesn't beep if you have it off), tpms light is on (needs sensors maybe? dont know), 4) rear wiper inop those are direct quotes -- however, on the test drive I found several other issues which were alarming. 1) a bad wheel bearing in the right rear wheel was extremely loud, sounding like an airplane taking off on the highway, this was not mentioned in any way before test driving. 2) the brakes are weak and the rotors warped, pulsating during braking 3) the radio did not work and gave an "error" code 4) the seat belts have very dark markings on them either from wear or mold 5) missing rear passenger side seat 6) broken rear ventilation (blower motor likely) I thought I should report this as it was not mentioned and upon checking online this is a serious safety issue. I am surprised they passed it. [xxx] this vehicle is still for sale. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On November 12, I was on the highway in the right lane, there was a car about 4 car lengths ahead of me in my lane and the car in the middle lane was quite a distance ahead. Just as I got in the middle lane, boom! the vehicle's cmbs malfunctioned and slammed on the brakes - no warning, visual or audible, just came to an abrupt stop. Thank goodness no one was behind me or I would have been dead. It was an instant whiplash effect as well and then as I was then merging back into the right lane to exit the highway, it did it again! there were no cars anywhere near me as I had slowed down due to the trauma from the first braking malfunction and all the cars were quite a distance ahead and thank goodness there were no cars behind me. Then on November 25, the same thing happened again. Driving down the highway, no cars near and boom! I am brought to an abrupt stop in the middle of the highway! the cmbs malfunctioned again in the middle of the highway. I took it to the dealer and conveniently there were no codes so they said there was nothing they could do. Someone needs to do something about this! to answer your questions 1) cmbs system is malfunctioning and has been for quite some time on Honda vehicles 2) if there would have been a vehicle behind me, I most likely would have been killed. If my dogs would have been in the van, they would have been injured. It gave me whiplash 3) I took it in and they did nothing until I complained, then they kept it a second day and drove it and said it didn't do it. But they weren't even going to do anything until I pushed the issue. This is a known issue with Honda as I found out after it happened to me. 4) the dealer 5) absolutely no warnings before it happened.

I came to a stop at a stop sign. Then "auto off" shut off the engine. Next, the vehicle went into park. A message came on screen telling me to press the brake and the start button. Doing so had no effect. Cars behind me started honking. After repeatedly stabbing the start button and opening and closing my driver's door, the vehicle eventually rebooted, and the engine started as normal. This caused a dangerous situation where other cars went into opposing traffic to get around me.

The multipurpose camera failed showing lot of error codes. This affects the braking system putting my family and kids in risk. Honda is asking 2000$ to fix the camera.

I have had multiple issues with the radio (16000 miles). After many personal videos dealership was able to fix one of this issues with a new part (22000 miles). I was informed the other issues I was having with the radio was due to my battery not staying fully charged. I was also having issues with the van not starting right away, which made me feel I could get stranded. It took many attempts to get the van to start. The van also wouldn't let me reverse one time, with a message telling me to place van in park. Another issue is the van is very slow to restart from auto idle shut off. The transmission is slow to change gears in lower gears and the van jerks a little bit. Next my rotors were warped. I was informed by the dealership that there was nothing wrong with my transmission and the auto idle down was working properly. No one could explain the rotors being warped. They reshaped my rotors and replaced the battery and told me they hoped that fixed the problem. Well indeed it did not fix the problem. As of 12/27/25 the van completely shut off at a stop sign and again on 12/28/25. The issue is only getting worse (24,000 miles) and now I am scared to death that the van will stop while I am driving. The dealership has been contacted and I am waiting on a call back for a loaner car. I was in traffic and was extremely worried about my safety, as well, the safety of others around me and with me. ( side note I returned the van to another dealership soon after the first dealership performed work on the van, when I heard a metal on metal sound and what sounded like a bolt rolling around in my back brakes. They did not find anything wrong but were also puzzled by the rotors already being warped. I was afraid to make the trip to the orig dealership). I have recently gotten a video of the brakes scraping again. This van is causing a lot of safety issues for my family.
