Service Brakes Problems of Honda Odyssey - part 1

We recently moved from [xxx] to [xxx]. The first time driving down a mountain the vehicle violently shook when applying the brakes to keep the speed under control. Upon taking it to a Honda service location, the technician revealed hot spots on both front brake rotors. The van has only 21319 miles, and the rotors needed to be replaced with new rotors to make the vehicle safe. The service representative refused to file a warranty claim with Honda because he said “rotors are a wear-and-tear item. ” the warranty states bumper-to-bumper coverage for 3 years, or 36000 miles, but does not cover normal wear-and-tear. These hot spots were not normal wear-and-tear. Nonetheless, the representative refused to file a warranty claim unless I was willing to leave the car at their shop for 48 hours or more while they wait for a response, and emphasized that “I’ve never seen Honda accept this claim. ” upon further review of the brake specs, it seems that Honda uses cast-iron oem rotors which may not be suitable for normal wear-and-tear for a 6000 lb vehicle. To make matters worse, the new oem brakes are only warrantied for 12 months/12000 miles whereas a non-Honda service station would have installed a heavy-duty brake for less cost and also warrantied it for 3 years/36000 miles.

The contact owns a 2026 Honda Odyssey. The contact stated that while pulling halfway into a parking spot with her foot on the brake pedal, the vehicle suddenly accelerated, turning slightly right to miss a handicapped spot, crashed into a palm tree, and drove over rocks before the vehicle stopped. The vehicle went from 0 to 30 mph within seconds. The ignition was turned off during the failure. The driver’s side seat and top air bags deployed and struck the contact in the face, causing a burning of the face. There was smoke inside the vehicle. The driver was able to exit the vehicle. The contact sustained bruises. The driver's son was seated in the driver's side rear seat. The air pressure warning light was illuminated. The vehicle was taken to the local dealer for an oil change the day before the failure. The vehicle was towed to the residence and then later towed to a geico lot. The insurance company had inspected the vehicle. The vehicle was scheduled to go to a body shop for further inspection. A police report was filed. The failure mileage was approximately 6,338.

On Tuesday, September 8, 2026 while sitting idle at a red light I had my foot on the brake and when the light turned green, I went to push on the gas and the van would not go, nearly causing the car behind me to rear end me because they figured I was going since it was a green light. I turned my hazard lights on, and there was a warning that appeared on the dash but I did not catch what it said in time. When I looked down, the car had put itself in park so I shut the van off and when I turned the van back on, there was a red battery light on the dash and it said “ to continue to drive depress brake pedal and push switch”. The van would not go into gear so I then had to call police (I was blocking a traffic lane) and a tow truck. The van is still at our local Honda dealer where it was purchased and to my knowledge has not been looked at-today is day three of the dealership having possession of the van. Also, on the same day-two stop lights previous to this it had a severe lag from brake to gas.

?the multipurpose windshield camera module in my 2019 Honda Odyssey experiences an internal electronic/power failure (diagnostic trouble code u3000-49) while driving. This failure triggers a cascade of warning lights across the dashboard, instantly and without warning disabling the entire Honda sensing driver-assist suite—including collision mitigation braking (cmbs), lane keeping assist (lkas), road departure mitigation (rdm), adaptive cruise control (acc), and auto high beams.

When I was at the set of lights my vehicle put itself in park and refused to go back in drive. The dashboard started to flash "shift to park" cars were honking at us people we screaming because we weren't driving when the light turned green. But my car refused to go back into drive. I had to shut it off and turn it back on. I had all my kids (5) in the car. I brought it to the dealership and they said that there was no code recorded. And because of that they couldn't do anything about it. Almost as if it didn't happen. Then it has recently happened two more times. I'm bringing my vehicle back in to the dealership, but they told me if it didn't record a code then they couldn't really do anything about it. It was of the scariest things to ever happen. 21.

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.

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.

My Odyssey randomly began displaying all of the adas warning messages: the brake system indicator light comes on, forward collision warning, lane departure warning, lane-keeping assist, auto high beam system error, etc. These came on beginning 7/25/26 and have come on everyday since causing the entire adas system to be inoperable. There have been a few days that they didn't come on immediately. I have had a few days where they came on half-way through my drive. This is a safety issue due to a defect in either the front camera or wiring to it, a nuisance, and something Honda needs to correct. It seems to be way too common of an issue according to my research. There hasn't been any damage to the van and no reason for these to come on. I have done research and see this has happened to many people. The replacement camera is costly as well as the calibration. Therefore, I haven't taken it to the dealership but I have discussed the issue with them. They agree that the camera is getting too hot and failing, which is causing the errors and of course all of those safety features fail simultaneously.

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

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.
