Vehicle Speed Control Problems of Honda Odyssey - part 1

I am reporting a safety issue involving my 2019 Honda Odyssey transmission. Since early ownership, the vehicle has had ongoing hesitation and delayed response when accelerating, especially during gear shifts. Over time, this condition has worsened and now includes intermittent loss of power when pressing the accelerator, followed by sudden jerking or lurching forward. The most serious incident occurred recently when the vehicle unexpectedly shifted into park while moving in a parking lot, creating a dangerous and unsafe condition. Additionally, there have been multiple instances where the vehicle hesitated in intersections, creating a risk of collision due to lack of response when attempting to accelerate. Honda dealership technicians have acknowledged that these vehicles are known to have rough or problematic shifting, indicating this may be a broader issue. The final issue has resulted in the vehicle being towed to the dealership for a full evaluation.

Five days after getting back our car from the Honda dealership where they “fixed” the two recalls all warning lights came on and not turn off. Steering, breaking, accelerating all are difficult. There were no issues prior to the dealership “fixing” the recalls. The car was just at our mechanic for brakes and they check our engine, fluids etc every time. There were no prior issues.

Multipurpose camera unit/millimeter wave radar internal electronic failure diagnosed with u3000-49 error code in my 2019 Honda Odyssey. The problem has been confirmed by the Honda service center and reason stated is low heat resistance. Coat of repair is approx $2000 and this is purely due to low heat tolerance levels of the Honda component.

One week ago, I was driving on a highway, accelerating to the 65 mph speed limit on that road, my van's accelerator completely stopped responding. Despite pumping the pedal repeatedly, I was unable to control my speed at all, and the car continued to lose speed. I had my three children in the car at the time, and given that people regularly go in excess of 70 mph on that road, I was in danger of not being able to exit the road and/or being hit. I was able to coast off of onto an exit, and the car started responding at speeds of 30 mph, but it was lurching and jerking while driving. We immediately had the vehicle inspected by an independent mechanic and have been advised that the transmission needs to be replaced. There were no warning lights for this failure. The car also had an incident about a year ago where all lights came on and it stopped responding. At that time, we had Honda dealership examine it, and they said they could not find any issues. Additionally, the car has been jerking slightly while shifting, but the issue improved when we had the transmission fluid flushed at the Honda dealership again about a month ago, and no issues were noted by them at that time. We have performed regular maintenance and safety inspections on this vehicle.

I am submitting this complaint to report a serious and recurring safety issue with my Honda Odyssey involving the camera system. Multiple warning messages and fault codes appeared on the dashboard simultaneously, including: -collision mitigation system problem -adaptive cruise control problem -lane keep assist problem -auto high beam problem these systems are all disabled. This failure occurred without warning and immediately compromised several critical driver-assistance and safety features. We have serviced at Honda dealerships and they said the only fix is a new $1500 camera (but the camera still works). Despite this, no recall has been issued. We have owned Honda vehicles for decades and never had these type of issues. A recall needs to be announced and owners allowed a fix at no charge. The transmission warning lights are also coming on intermittently and we paid to have Honda diagnose. The transmission is fine they said. Please help.

The contact owns a 2004 Honda Odyssey. The contact stated that while driving 45 mph and depressing the accelerator pedal, the vehicle failed to respond as intended. The contact pulled over to the right side of the roadway, turned off the vehicle for approximately 30-minutes before restarting the vehicle; however, the failure persisted. The vehicle was towed to her residence. The failure had occurred several times. The vehicle was not taken to a dealer or an independent mechanic to be diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 284,000.

Today ( Dec 30, 2025) . My wife was driving my Honda Odyssey on highway 287 east NJ ( closed to livingston NJ ) . Here is the whole thing : the Odyssey suddenly stopped while my wife was downshifting. At that time, there was a car in front of our car at least 30 feet away. Once the car stopped almost completely. Some red warning letters were shown on the front dashboard. But since we all filled in in a big panic, no one saw what those words were. At that time, we felt the minivan vibrating. That is all we could recall since we were still trying to calm down. I am not sure it was still the same problem with the transmission we reported months ago. That is the whole store for today. And I also attached the last note I sent to you. Hi , to whom it might concern, to further the conversation, we had talked with the local Honda dealer, and they had test-driven it several times, but they insist there are no problems at all. They suggested that we replace the transmission fluid to improve the performance. We replaced it in the dealer store. But from the fall of this year, 2025. We feel the Odyssey has the same problems again : 1. The vehicle struggles to accelerate quickly when the accelerator is pressed. 2. The vehicle accelerates, but there is a noticeable jerking sensation. 3. After pressing the accelerator, the engine rpm increases significantly (the engine noise also grows louder), but the car itself does not accelerate immediately. It takes several seconds before any noticeable increase in speed occurs. I checked online I noticed that in some cases, some Odysseys stop on the highway and cause some injuries, which is terribly I also sent a note to Honda USA, and I got a reply, but it is useless. I do not know what I can do. I saw there was some recall (due to the transmission) on othe dyssey touring model and elite models, but I wonder if there is any recall on my Odyssey ex-l model.

Upon starting the vehicle, it failed to engage in reverse. Although the backup camera activated, the vehicle remained stationary. After multiple ignition cycles, the vehicle eventually engaged in reverse and then moved forward in drive. However, shortly after, the vehicle experienced a sudden loss of power and entered "limp mode," restricting speed to approximately 15–20 mph regardless of throttle input. The engine revved excessively high without corresponding acceleration, and a severe burning/heat smell emanated from the transmission/engine compartment. This failure occurred without any prior warning; notably, no dashboard warning lights or "check engine" indicators illuminated to alert the driver of a mechanical or electronic fault. The sudden, un-signaled drop in speed on a public roadway created a significant safety hazard for following traffic and risked a rear-end collision. The vehicle was towed to a certified Honda dealership where the transmission control module (tcm) was diagnosed as failed. The tcm is currently being replaced under the Honda certified pre-owned (cpo) warranty. We do not know what else requires replacement and repairs. The dealership will not cover the replacement of the transmission fluid, or engine fluid, despite the fluid being subjected to extreme heat and potential damage during the failure and subsequent limp mode.

My vehicle stalls when I turn left or right from a stop light or sign. It’s incredibly dangerous especially when I have my kids in the van with me. We’ve taken it to the Honda dealer for repair and they’ve done work but the issue has not been resolved. I’ve seen countless forums of people with this year make and model who have had the same issue. I don’t know why there’s been no recall but someone is going to get seriously hurt if this issue is not resolved.

Camera projector fail and 6 warning ?? lights came on, very common issue.

I am submitting this urgent complaint regarding my 2015 Honda Odyssey, equipped with the 3. 5l v6 engine referenced in (TSB) 20-023 which acknowledges that the front rocker arm oil control valve (spool valve) gasket may fail and leak engine oil directly onto the alternator located beneath it. This condition can cause alternator contamination, charging system failure, electrical malfunction, and potential fire risk due to oil exposure to electrical components. Despite knowledge of this issue, Honda did not notify vehicle owners and did not initiate a recall. Before the first breakdown occurred, I experienced a frightening and dangerous incident while in traffic. Without any human interference and without my pressing the accelerator, the vehicle suddenly accelerated and moved forward on its own, nearly striking the vehicle in front of me. I had to react immediately to prevent a collision. This unexpected surge was extremely disturbing and appeared to involve an electrical malfunction. Shortly thereafter, the vehicle broke down. After the first breakdown, I replaced the battery. Within approximately one hour of driving again, the vehicle failed again due to alternator failure. I was stranded at night, in darkness, alone, and exposed to active traffic. This created an immediate and foreseeable risk of collision, serious bodily injury, or death. Another car in that area around that time broke down on the highway I was expected to use and was hit by a semi on 95 and the driver of the stopped car was killed. That could have easily been me. A defect that can cause sudden electrical malfunction, unintended vehicle movement, loss of charging capability, vehicle disablement in traffic, and potential fire hazard constitutes a safety-related defect under federal motor vehicle safety standards. I respectfully request that you initiate a formal investigation evaluate whether a recall is warranted. Require reimbursement for repair costs thank you very much.

Observed repeatedly while operating at highway/interstate cruising speed, with adaptive cruise engaged: any changes in road texture - concrete to blacktop, between different types of blacktop or concrete, separation joints, etc - such as when crossing a bridge, crossing state lines, entering open-road toll plazas, etc - results in a sharp lifting of the throttle and at times will also automatically engage the brakes. This results in rapidly and unexpectedly cutting speed by 10-15 mph before automatically resuming set speed 1-2 seconds later. This has resulted in trailing vehicles to think I am brake-checking them or otherwise caused them to abruptly brake or swerve out from behind me. It also can cause driver and occupants in the Odyssey to lurch forward and back unexpectedly - which has had a residual affect of unintended input on the steering wheel, cascading into unintended direction change and amplifying vehicle instability issues already introduced by the sudden speed change. There are multiple other owners of 2018+ Odysseys on the forum [xxx] which have reported similar situations. I have tried to encourage them to register their observations here. I believe this issue poses a significant risk to the operator and occupants, as well as surrounding motorists. Rental/fleet vehicles with drivers who are otherwise unfamiliar with the issue would be at exceptional risk. I have experienced this issue numerous times as I live near & frequent highways and interstates with these types of road conditions nearby.

We purchased our 2018 Honda Odyssey in January of 2024. Since we purchased the car, it regularly hesitates from the stopped position. This regularly yet intermittently causes a safety hazard when turning right into traffic or making a left turn because the acceleration does not work and feels as if it is failing for 2-4 seconds. There is a recall with other models that are the same year and close to with similar issues however ours is not included. I have now reported it to the dealership multiple times and am told they cannot replicate it so they can't help me. I was also told that there is a lag with this engine which causes teh delay but they have no concern. This causes performance issues, and puts me in a precaious situation oten when making a left turn or trying to cross multiple lanes of traffic. This issue really needs to be fixed and covered.

I have a Honda Odyssey 2016 with low mileage, which I purchased almost 2 years ago. This has happened twice. While driving in traffic, I approached a stop light and applied my brakes. When I applied the brakes, the engine accelerated at the same time propelling the car forward. I pressed on the brakes as hard as I could to keep the car from hitting the car in front of me. The second time this happened, I was able to turn off the ignition and then restart it. This is a very dangerous situation because it is extremely difficult to control the car and keep it from moving ahead. I used all of my strength to push against the brake to keep the car from moving ahead. There are other instances of this identified online if you search for it. There needs to be a recall or a way to fix this problem. I took the car to the Honda dealer on October 8, 2025. He kept it for four days and examined it thoroughly but could not find anything wrong with the car and could not get it to replicate this behavior. I never know when the surging forward might happen.

Van completely shut down while in an intersection and the battery light came on. It was hard to restart. Took it to the dealership and they cannot find the problem.

Front camera failure causes multiple safety issues. Lane keep assist collision mitigation road departure mitigation high beam problem this is a known issue and the dealership knew about this immediately hearing the multiple warning signs. Cost of replacement is over $2000.

Adaptive cruise control unexpectedly disengages. This has happened dozens of times, consistently every time I use the adaptive cruise control on the highway. My speed drops from the set speed (for example, 75 mph) down to 55 or 60 mph, at which point I realize it’s not going to come back on. This is extremely dangerous on the highway, and puts me at risk of being rear-ended by vehicles traveling at high speed.

Issue description: my 2018 Honda Odyssey (VIN: [xxx] ) has a total failure of the multipurpose camera, permanently disabling the collision mitigation braking system (cmbs), forward collision warning (fcw), and lane keeping assist (lkas). In addition to these, the regular cruise control is also disabled. These are primary safety systems, not elective conveniences. Persistent failure: errors occur immediately upon every startup. Mid-drive danger: systems have deactivated multiple times while in motion, causing sudden, unpredictable loss of driver-assist features at highway speeds. Total loss of control: both adaptive and standard cruise control are completely disabled, forcing manual-only operation. Infrastructure failure: the failure prevents the vehicle from recognizing lane markings (rdm/lkas), leaving the car unable to assist in steering corrections. Safety risk: the vehicle can no longer perform emergency braking or provide collision alerts, significantly increasing the risk of high-speed crashes. This is a premature failure of a non-wear safety electronic at 91k miles. It is a severe safety defect that leaves the vehicle unequipped with the crash-prevention technology it was designed to have. Manufacturer response: american Honda (case #16167889) and ncds (case #xxx) denied assistance, citing the expired 3yr/36k warranty. I contend this is an extension of the known electrical architecture defects in this model year (e. G. , recall 23v-431), and a component intended for the life of the vehicle should not fail such that it disables multiple safety systems simultaneously.

Windshield monocular camera overheated. No longer working.

Bought our 2022 Honda Odyssey in November of 2021. Vehicle has the idle/stop feature. That feature never worked properly. Always said, warming up or charging and didn't work. Recently, June 7, 2025 my wife driving was at the light with the stop feature activated, she took her foot off the brake for it to start up and it was shifting weird. Happened several times. On June 11, 2025, I was at a light and when I let my foot of the brake for the feature to start the vehicle, the vehicle stalled and I couldn't get it in gear. Eventually it went in gear. I could've gotten into an accident. I called the dealership on June 11, 2025 to make an appointment. After seeing something else on the news about a recall, I decided to look up my issue. I found that there is an investigation and lawsuits about it. I had no idea. I had no idea a letter was sent to owners. I never received it!! I looked at my service records and on February 15, 2024, at an oil change, the dealership fixed a recall per Honda for auto start and says updated. My vehicle is still having issues.

On Saturday, may 24, 2025. I had my foot on the break as I was turning into the driveway of the building. Suddenly the car engine reved and the car acceletated toward the building wall. As this was happening I began to pump on the break and the car only stopped because it it hit the curb. This cause my passenger and me to lunge forward. My passenger hurt their wrist putting their hands on the dash as they braced for impact and I hit my forehead on the stearing wheel. . The airbags did not deploy. My cars front bumper was pushed in at the bottom and out on the right side. Thank god there was no one walking on the side walk,. The car could have crashed iinto a person or the building. There were no warning indicators . There was no police called since no one was seriously injured and the only damage done was to my car. I then carfully and slowly drove the car home and parked it. I had to wait till Tuesday to take the car to the mechanic. He kept it for 2 days and could not find anything wrong. This was very scary and I am afraid the continue driving this car. This had never happenef before. I would like the car checked for any recalls and inspected by the dealer.

I have had four diagnostics on this vehicle and it's pointing to sensors which are inside the transmission transmission was not leaking and wasn't slipping or nothing I went to get in the vehicle after it was sitting for an hour and I put it in reverse it went right back in the park I put it in dry went right back in the park I couldn't get it out of the park and it was saying on the dash that stop driving one safe transmission problem emission system problems okay like a four diagnostics that are saying that it is sensors transmission pressure sensor a park neutral switch is bad power source failure steering angle low voltage sensor failure four different things I cannot get any help I hear a bunch of different stories some are saying the transmission not so we're saying it's not a transmission isn't slipping I drove it car was fine it won't go into drive I've been told and I researches so much that if it's happened on the road it could slam in the park the be able to roll they could crash it's a very bad safety issue there are recalls on 50,000 of this year of the Honda Odyssey I'm being told that my VIN number is not on the recall list I don't understand why not it's doing exactly what all the other 50,000 recalls are doing and I can't get help fixing mine.

We have 2020 Honda Odyssey with 4500 miles and multi purpose camera quit working and Honda service center ran a scan and confirmed malfunction of camera and replacement costed over $1600. Internet tells me that many other similar vehicle have similar issue. It should be a recall and fixed free.

Stalling lagging on acceleration. Leaving me stranded in the middle of road or intersection. Honda dealership says they can duplicate the issue, but there is no fix.

Vehicle has hesitation when resuming forward drive after sitting at a light or taking left hand turn. The hesitation causes the feeling of not moving at the amount of speed the car should when starting to regain driving motion, then suddenly slams into gear and proceeds forward with a too quick acceleration to adjust to the amount of pressure applied to gas, causing the driver to have to hit brakes before hitting car infront of them.

Multiple warnings occurred simultaneously when I started my car I been doing a research on the web I found out that many buyers have the same problem with their van's and already reported here is the list that found 2018 2019 2020 Honda Odyssey touring and ex-l , I found out that the camera/sensor in the windshield (near the rearview mirror). It needed to be replaced. Their camera has an internal failure!!! this needs to be recalled.

The impact on the car is we no longer have cruse control (basic feature) and every time we turn on the car we see many warning lights turn on. Some other feature that does not work is lane assist does not work. According to what shows up to on the dashboard there are problems for "road departure mitigation system problem", "auto high-beam problem", "adaptive cruse control problem", "lane keeping assist problem", "collision mitigation system problem", "break system", "left sliding door problem" a quick search on the web indicate this a common issue with Honda car (including Acura). [xxx] another problem we're seeing is driver side sliding door does not close correctly or open correctly. We have since stop using this door since it's very dangerous for our kids since while opening, it would not open all the way and close on the kids. Similar issues [xxx] these two things are broken under 65000 miles and less than 6 years owning the car. 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.

Since 2023 around August I felt lose of power while driving but I thought its because of the gasoline I used so I didnt care much , thereafter this loss of power problem persisted since then so I took to the dealership at battison Honda at nortwest expressway in oklahoma , but they said my vehicle has no issue , but this loss of power issue was not resolved but on 1st week of February I was about to crash on road due to loss of power so took the vehicle to dealership and they said it was due to the trasmission issue and I replaced it as it passed the 5 year powertrain warranty dealership said I have to pay it full , I fight with them for 2 weeks atlast they said I have to pay 5000 dollar . So I paid the amont and they said the transmission has replaced , but still I have some hesitation while accelerate and the same issue of loss of power during acceleration happening , can you please help me to resolve this issue as its not only about money but due to safety concerns , I dont want to deal with trhat dealership anymore . Please help me during this difficult situation . Thank you .

The Honda sense front facing camera has went out on my 2018 Honda Odyssey. The camera is currently still installed in my van and if it is necessary to replace to keep it from draining the battery I will request that the faulty part be provided to me. This camera being faulty causes the loss of cruise control, adaptive cruise control, auto high beams, lane keep assist and emergency breaking. This issue is also causing a drain on the battery, which impacts other items due to low voltage. My van is currently at the dealership and I am being told that I will have to purchase a new camera which will be around $1500. The following lights are on; breaks, acc and lkas. These items first appeared within a few weeks of having the rear camera recall completed. Based on my research this is a common problem and just like the rear camera recall, Honda should have to replace this camera as well. The date provided is the date it was officially diagnosed by Honda, the lights appeared in 10/2024 and all of the functions were lost around that time.

I am reporting a serious safety concern regarding my 2019 Honda Odyssey, which poses a risk to me and my family. The issue is intermittent, making it difficult for the dealership to replicate. The problem began when the collision mitigation system warning light flashed, indicating a system malfunction. This was followed by multiple warning lights appearing on the dashboard. At times, the entire dashboard and screen go blank, and all gauges shut off while I am driving on both city streets and highways-though the engine remains on. Additionally, I have experienced the following issues: the steering wheel stiffness when making turns, the vehicle hesitates to accelerate after being at a stop. In December 2023, I took the vehicle to a Honda dealership, where they recommended replacing the front camera/sensor (behind the rear mirror) at a cost of over $1,500. 00. I proceeded with the repair in December 2023. However, the same issues returned in January 2025. This defect poses a severe safety risk, especially when driving at higher speeds or in traffic. Since the dealership has been unable to diagnose the issue due to its sporadic nature, I am requesting an investigation into this matter to determine if other owners are experiencing similar safety risks. Thank you for your time and attention to this issue.

Did not control speed sometime up and down engine.
