Electrical System Problems of Honda Odyssey - part 2

The rearview camera that does not display an image which can reduce the driver's rear view, increasing the risk of a crash or injury. I had the vehicle inspected by a third party which believes this could be from insufficient repairs as part of the prior recall NHTSA id number: 23v431000 related to this same issue. Honda's recall service center's only solution is that I take the vehicle to a Honda dealership for inspection, at my expense, and that they will reimburse me if they determine it is related to this recall. The issue with the display not working has been going on for several weeks. The display will work temporarily when the battery is reset, the fuse is reset, or when the display itself was removed/replaced by the party I had inspect the unit.

I see the NHTSA is aware of the issue with Honda Odyssey autostart failing to restart the engine which causes the car to need to be restarted fully while stopped in the middle of traffic. I had this issue many times, my car was serviced with a new battery and 2 months laters its starting again. As an aside one of the front parking sensors will randomly go off which can often cause me to turn off the array. Cleaning didnt help.

Multiple Honda sensing safety systems (collision mitigation, lane keeping, road departure, adaptive cruise, and auto high?beam) disabled suddenly on 2020 Honda Odyssey ex?l around 76,000 mi. Dealer and two independent diagnostics confirmed dtc u3000?49, internal electronic failure of the forward recognition camera. The fault disables all automatic braking and lane?keeping functions. Battery voltage and calibration verified ok; component failure is internal. Honda quoted ~$2,000 repair. This is a significant safety risk since all advertised crash?avoidance functions stop working.

As I was driving the car computer showed overheating, brake failure, transmission failure and the car started shaking and the engine died. I had the car towed by triple aaa to a auto repair shop, but the next day when they went to fix the problem could not replicate it.

Complaint description: while driving my 2025 Honda Odyssey, the auto idle?stop system engaged in the middle of an intersection at a traffic light, shutting the engine off as designed. When I released the brake pedal, the engine failed to restart, leaving the vehicle stalled in traffic. The dashboard displayed warning indicators including the battery light, and the only way to move the vehicle was to turn off the car completely several time and try to manually restart the engine. This issue has occurred multiple times and poses a serious safety risk, especially when it happens in intersections or heavy traffic. I almost got hit by an oncoming car! on each occasion, surrounding traffic was forced to maneuver around my vehicle, creating the potential for a rear?end or a side collision. This has been happening for a long time now and these instances are occurring almost weekly at this point. They are increasing. I have seen that other 2025 Odyssey owners are reporting the same issue — engine shuts off after auto idle?stop activates and will not restart — sometimes requiring a full restart and causing dangerous traffic situations on carfax. Com. Based on similar NHTSA?documented complaints and investigations into Honda auto idle?stop restart failures, this appears consistent with a known defect pattern involving stalled engines and failure to restart after idle?stop engagement. (lawinfo. Com and edmunds. Com) the dealership has already replaced my low pressure fuel pump and state that they are fulkly aware of the issue and have not provided a permanent fix, and the problem continues to occur unpredictably. My wife and 4 children are in this car all the time. This defect could easily lead to an accident if the vehicle becomes immobilized in moving traffic. I am reporting this to ensure it is documented as a potential safety defect requiring investigation and mitigation.

**vehicle:** 2019 Honda Odyssey **components affected:** forward collision avoidance, lane departure, adaptive cruise control, braking system, exterior lighting, electrical system, instrument cluster **complaint summary:** multiple safety systems on my 2019 Honda Odyssey 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, 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.

Defective body seam on roof panel over drivers side rear wheel - resulting water leak on control panel for power liftgate caused the rear tailgate to continually open and close while driving. The vehicle was parked and the fuses controlling the tailgate were removed to enable the closure of the hatch and allow vehicle operation. Prior to this, the vehicle battery died while parked due to the continuous tailgate operation and required a battery jump. The vehicle was taken to d&j auto (an independent service center) where a previous liftgate control panel was replaced for failure to open the tailgate. A search of the internet on 2018 Honda odyessey liftgate problems revealed multiple instances of water leaks on the liftgate control panels due to body seam issues which caused liftgate failures. This information was relayed to the auto repair shop where the leak was discovered. The vehicle was taken to a body repair shop across the street where the seam was fixed, returned to the auto repair shop where a third tailgate control panel installed.

Automatic idle stop function fails. The car idles down while at a stop and then the entire car will shut off and fail to restart. This occurs frequently at stoplights, stop signs, in traffic or any time the vehicle idles down. The car fails to restart right away resulting in multiple attempts to start the engine and poses a danger to occupants in traffic.

Since purchasing this vehicle brand new off the truck, we have had it back at the dealership multiple times ,we've taken it for the plug in console not working for firesticks, a sensor not working on the passenger side door and claiming it to be open, the sliding door not working correctly, the doors locking and refusing to unlock, battery draining, ac not working, stalling, dying at lights, slamming on its own brakes with nothing around, transmission acting weird, it putting itself in to sport mode, transmission sticking, doors not unlocking or not locking, sensors going off, random errors on dash, screens not working, car play not working, suspension popping, steering being wiggly and loose, brakes squeeling. Today we were told by the dealership "he saw the damage that is resulting in needing to replace the steering column. With that being said, it is considered a safety hazard to drive this vehicle with the condition the steering column is in. " this is after multiple times of saying nothing is wrong to we have to charge the battery to you need a new starter to this.

The vehicle will shut off at stops after the auto idle stop engages. We have to turn the vehicle back on and press the "off auto idle stop" button to not have this happen. I will enter the last date we noticed this below.

The computer system for the sliding doors and back hatch do not work properly. They will occasionally stop working or will stop mid-open or close. In addition, on three separate occasions the sensors did not work. One time the back hatch started to close while I was getting something out of the trunk. It did not sense by body and would not stop. I tried to stop it physically but the hatch continued to close. If I had not gotten out of the way, it would have crushed me. This happened to my husband on a separate occasion as well. He is athletic - [xxx} and [xxx] and was pushing up with all of his strength and the hatch continued to close on him before he had to jump out of the way. On the third occasion - the sliding side door started to close on my [xxx] as I was helping him into his car seat. This issue will kill someone. The 2019 Honda Odysseys need to be recalled immediately. I alerted my local Honda service center (don jacobs in lexington, ky). I asked them to notify Honda and they told me they wouldn't do that unless more people had similar issues. They have attempted to fix the computer system on several occasions and always say the issue is fixed. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Auto start/stop system engaged, when given gas the engine did not start. Battery light came on and had to turn off and on the vehicle to start the engine. Ea25004 - investigation [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle completely stalled, we believe it’s related to the engine in reference to the idol on and off mechanism. We began to drive forward and the auto on off starter caused the car to completely shut down and freeze in an intersection.

Vehicle experiences engine stalling and failure to restart at intersections when the auto idle stop (ais) feature is engaged. This creates an immediate life-safety hazard as the vehicle becomes non-functional in live traffic. This has occurred 2 times. Once on surface streets and once on the highway in stop-and-go traffic. This issue persists despite service bulletins 23-008 and 23-009. Honda corporate and Honda dealership refusing to cover the repair. Separately, during a 37-day repair attempt (Jan 22 – March 2, 2026), autonation Honda chandler admitted the vehicle was sold with an 'incorrect' battery type (lead acid instead of required agm), which caused electrical instability. The dealership attempted a repair on Feb 13, but the vehicle failed to start again on Feb 11 during a pickup attempt. The dealer has since refused to provide accurate service records or further communication. The vehicle remains unsafe to drive as it continues to stall randomly.

The contact owns a 2024 Honda Odyssey. The contact stated that while stopped and using the auto start/stop feature, the vehicle failed to restart as designed. While attempting to restart the vehicle, the battery warning light flashed on the instrument panel. The vehicle restarted after several minutes. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 41,000.

After I received a software update for my 2018 Honda Odyssey elite the car has been stalling when idle. It is very dangerous because I will be at a stop light in drive, and the vehicle will shut off with no power. Cars will be behind me or no cars, and I have almost been rear ended. I did not have this problem until I received the new software update. It keeps occurring more and more often.

Power tailgate stopped working. Warning indicator indicated power tailgate failure. Dealer found water to be leaking onto tailgate unit from driver’s side roof rail. Recommended replacing and programming new ptg unit and resealing water leak. Repair cost was $1,311. 51.

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.

Idle stop failure. This has occurred many times. Presents itself failure to restart upon releasing the brake. Rough restart. Sometimes have to completely turn off car and restart.

Reporting a failure of safety recall 23-046 / NHTSA campaign 23v431000 on us vehicle. Post-recall 'remedy,' the vehicle suffers with the same most network error and from severe parasitic battery drain as described in Honda service bulletin 23-061. This led to a total electrical failure and vehicle grounding in -24°c temperatures. This systemic most bus network defect was previously the subject of the conti v. American Honda (2:19-cv-02160) settlement. The vehicle is currently grounded at a dealership in canada, and Honda canada refuses to acknowledge the failure of the recall remedy or the resulting consequential damages (battery/starter failure). I am filing this to report an ineffective recall remedy on a us-certified vehicle. I have tried establishing contact with Honda us however there has been no response from them.

The car stopped while driving in the middle of the street and would not turn off or on.

I reported issues regarding egress failure and children stuck within the back seat of the van, electronic dashboard failing while driving, and no start issues amongst others (11709419). Previously the certified dealer stated the issues just could not be reproduced, despite my videos, however, today they stated a Honda admin level director showed and told them the issues are being reported by others, they dont know how to fix it, and I need to come get my car, continue driving it.

The contact owns a 2024 Honda Odyssey. The contact stated that while driving at an undisclosed speed, and while stopped at a red traffic light, the automatic start/stop system failed, causing the vehicle to unexpectedly shut off. The vehicle was restarted and drove normally. On another occasion, while stopped in a drive-thru, the vehicle shut off unexpectedly. The emissions system, adaptive cruise control, and tire monitoring system warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed with battery failure. The battery was replaced; however, the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 22,000.

The trunk door stopped working due to a leak from the rear left window seal causing the computer to become waterlogged the mechanic that fixed it said its a common issue with the Honda Odyssey and should be recalled by Honda, I am therefore requesting the NHTSA to investigate this matter further so Honda should reimburse for the cost of the repair this issue can be a safety hazard in the event of a emergency egress from the trunk as it's not possible to open from the exterior and there was no prior warnings lamps or messages.

Tailgate malfunction - unable to open and close tailgate. Warning message on dash states - tailgate power failure.

My 2023 Honda Odyssey elite has recurring, intermittent safety-related malfunctions across multiple systems. The most serious issues are: (1) door lock/unlock and rear door opening failures preventing emergency egress (children trapped), (2) intermittent “no-start/no-response” where push-button start does nothing (no click/no crank and sometimes no lights/electrical response), and (3) intermittent dashboard/instrument/electrical abnormalities while driving. I also previously experienced dangerous driver-assist behavior including unintended automatic braking and lane/steering behavior in construction zones. Door/egress: rear doors sometimes will not open from inside or outside even when the vehicle audibly indicates it unlocked. I have video of my children unable to exit the back seat. This is an emergency egress hazard. No-start/no-response: multiple events where the vehicle appears electrically dead and will not start, then after waiting ~10–30 minutes it starts without a jump. Stranding hazard. Recent examples: 12/31/2025 – doors would not open initially; after entry, no lights/electrical and start button produced zero response; after ~10–20 minutes it started. 01/05/2026 – while driving, dashboard/instrument display went off; buzzing noise believed hvac related occurred. 01/05/2026 – after parking at costco, vehicle again would not start (zero response); after ~30 minutes it started. 01/06/2026 – locking/unlocking malfunction again; rear doors would not open despite audible unlock (video). Repair history: authorized Honda dealer (bell road Honda) previously stated “cannot reproduce,” replaced dvd/recall items and performed a “reset,” but did not diagnose root cause; problems returned worse. Honda customer service case opened. Injuries: prior unintended automatic braking event (reported around 08/29/2023) caused injury (my legs hit dash; child had marks from car seat) and near rear-end collisions. Request: investigate potential safety defects.

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.

Car doesn't start, has needed to be jumped almost 20 times in a year. Auto start stop has shut the car off in intersections.

Over the past month, I have experienced several incidents where my 2025 Honda Odyssey’s auto idle stop (ais) system failed to restart the engine after stopping at traffic lights. Each time, the engine did not turn back on when I released the brake, leaving me stalled in traffic and prompting error messages on the dashboard. There is currently no way for owners to permanently turn off this feature. When I took my vehicle to the dealership, I was told my starter was already having issues despite the car having less than 10,000 miles on it. This ongoing problem has made me concerned for my safety and the reliability of my vehicle.

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.

Since I own this vehicle, 3 times tailgate failed. I have done repair it twice in Honda dealership at paramus NJ. Now it happened again after a year of last fix. Instrument cluster = warning sign appears stays there. Somewhere on back = constantly sound beeping - when driving tailgate = does not open and if open some how, it does not close. Neither automatic nor manually. I have to drive vehicle since I have no choice. I inspected all fuse in front under hood and in rear at cargo area.

This is now the second time that we are having a rear hatch failure. With about 37,000 miles on this van, the control module shorted out due to water getting into it due to a bad seam (according to other Odyssey owners who are suing Honda for this). We could not get the hatch to open or close, so I paid the dealer to fix it. Honda did give us a check after the fact to cover some of the bill. Now, with less than 51,000 miles, it has happened again. The hatch will not open or close. In the event of an emergency, this is a major safety issue, to be potentially stuck inside the cabin. The hatch started going up and down randomly, and we could not control it. Now, it won't go up or down. This van is is a mess. Not only does it have this issues, but the rear back up camera still does not work, even though it was recalled. . . They would not honor their recall, and the brakes occasionally come on without cause, when going around a corner and there is oncoming traffic. It thinks that we are headed for a collision, and it's another safety problem here in the northeast. Honda needs to own up to their quality problems relative to these three safety issues.

Vehicle shuts down and will not restart. So far this has happened three times. After a long delay, took foot off gas, held brake and pushed start and would not start. On third attempt vehicle was very labored on start.
