2024 Honda Odyssey Owner Complaints

On 2 occasions now automatic Start/Stop system has failed to restart. First was approximately 5 weeks ago and Second was Monday 3 Aug 2026. Dealer on first occurrence said there was a loose wire. Have not been to Dealer on 2nd occurrence yet. Situation in both cases is the vehicle was seemingly operating normally with no warnings displayed and I stopped in traffic. When traffic cleared and I tried to proceed; the vehicle was non responsive and would not start when I activated the normal start sequence.

Car purchased July 4, 2024. Idle stop/start was working but after several months, it became defective. After driving for some time, idle stop/start wouldn't work properly and cut the engine off when idling. I would have to turn the car, open my door, and try to restart the car. It also occurs after parking, turning off the car and less than 10-15min attempt to restart. Most of the time, it'll start after 1 or 2 attempts. Except today 07/31/2026, I got home and parked. After 20min, I tried to start my car and after 10-15 attempts, it wouldn't start. After waiting 2 hours, the car finally started.

2024 Honda Odyssey with only 24K miles has a leak in the tailgate from bad welding in the body that is gathering water in the trunk. Safety isn’t at risk but I would say that the corrosion to any electrical items are at risk which will put me and my family and others at risk of something failing. Yes the problem has been reproduced and it’s a common thread on the internet. We will be taking it to the dealership to inspect since it’s still under warranty. No messaging of this from the car except the fowl odor.

The contact owns a 2024 Honda Odyssey. The contact stated that while the vehicle was parked and attempting to place her [XXX] child in the rear passenger’s side seat, the contact touched the door handle, unlocking the door, and placed the bag with the key fob on the floor of the rear passenger’s side. The contact walked around to the driver's side door, and the door was locked. The contact returned to the rear passenger side of the vehicle and became aware that the door was locked. The contact attempted to enter the vehicle but was unsuccessful. The contact called the Fire Department, and the front passenger window was broken to enter the vehicle. A Police report was taken, but the information was not available. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 30,000. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My minivan has had repeated electrical and safety-related failures since shortly after it was leased. The vehicle has died or failed to start five times, including multiple tow events. The first battery failure happened shortly after delivery, but we thought a light may have been left on and did not know to bring it in. The problem continued. The dealer has replaced the battery, recharged the battery, replaced the alternator, and later found an excessive parasitic draw, but the electrical problems have continued. The failures affect more than starting. The sliding doors have failed 30+ times by refusing to close and acting like something is blocking them when nothing is there. This creates a safety concern because passengers may not be able to safely enter, exit, or secure the vehicle. The instrument cluster has gone black on startup in Park about 10 times and has also blacked out or faulted while in use. A brake failure warning light appeared once. The backup camera intermittently dims so badly that I cannot see behind the vehicle while reversing. A service advisor observed this issue, but the technician could not reproduce it during inspection. The DVD/interior electronics, USB charging, and wireless phone charger have also failed. The power tailgate/trunk malfunctioned repeatedly before repair, including problems opening or closing and clicking. The front driver and passenger windows also do not roll down smoothly. The front window still shakes or drags even after two repair attempts. The vehicle has been inspected by authorized service centers and is available for inspection upon request. The exact root cause is unknown, but based on the repeated dead battery, charging, parasitic draw, door, display, camera, brake warning, interior electronics, and power window failures, the pattern appears consistent with an unresolved electrical or charging-system defect.

The idle start stop system on my 2024 Honda Odyssey sometimes works, and then other times will leave me stranded at a stoplight, making it a grave safety concern. After the engine does not restart you have to turn the car completely off put it in park turn it all the way back on and then continue driving. This is not related to any of the climate controls being onto high or energy being consumed. It seems to be a manufacturing defect.

Vehicle Safety Complaint – Automatic Sliding Door Injury to Child To the National Highway Traffic Safety Administration, I am submitting this complaint to report what I believe may be a serious safety defect involving the automatic sliding door on my Honda vehicle. On June 9 at approximately 5:00 p.m., while the vehicle was parked in a residential driveway, the automatic sliding door severely injured my [XXX] son. He had unbuckled himself from his car seat and slid out of the vehicle as the automatic sliding door was closing. I witnessed the entire incident. As the door closed, his entire hand, as well as the skin on his leg, became trapped in the door. The automatic sliding door did not stop or reverse after encountering his hand and leg. Because the door is automatic, I was unable to immediately release him and had to wait for it to reopen before I could free him. Those moments felt incredibly long while my son was trapped and screaming in pain. When I was finally able to remove him from the door, his hand was severely injured, visibly deformed, and had significant swelling almost immediately after the incident. To my knowledge, nothing obstructed the normal operation of the door, and the automatic sliding door was being used in its normal operating mode. The fact that the door did not stop or reverse after trapping my son's hand is the primary reason I am submitting this complaint. Immediately after the accident, I took my son to an urgent care facility. The providers there instructed us to seek immediate evaluation by a pediatric orthopedic specialist, and we went directly to a pediatric orthopedist. He was diagnosed with a broken hand. This injury has resulted in medical expenses, significant emotional trauma for our family, and a complete loss of confidence in the safety of this vehicle. I purchased this Honda because I have three young children, including [XXX] twins. I chose this vehicle because I believed its safety and convenience feat INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A

My 2024 Honda Odyssey has repeatedly failed to restart after the Auto Idle Stop system shuts the engine off at a red light. When I release the brake or press the accelerator, the engine does not restart as it should. The vehicle then shifts into Park or instructs me to place it in Park, and it is difficult to restart using the start button. This has left the vehicle disabled in an active traffic lane and creates a serious risk of being struck by another vehicle. I have been stuck at a red light with people honking at me and haven't been able to start the car for up to a minute. The problem is intermittent, and I do not know whether it is caused by the engine, electrical system, battery, starter, software, or power train. The Auto Idle Stop system should not shut the engine off if the vehicle may be unable to restart.

Incident

Jul 10, 2026

The Start/Stop function on the Honda Odyssey failed to re-start the vehicle after it was stopped at a traffic signal. The vehicle gave no advance notice of the issue. The vehicle defaulted the transmission into the "Park" position, however the electronics (radio, windows, etc.) all operated as normal. Simply pushing the ignition "On/Off" would do nothing and would NOT turn off the electronics. I had to press and hold the "On/Off" ( similar to a Ctl+Alt+"Delete") to hard shut off the vehicle entirely. I then had to place the key fob physically on the "On/Off" button to restart the vehicle. This is a significant safety concern being at a dead stop at a stoplight that may be green. We have had our van to the Honda dealer twice now within 3 weeks for the same issue. They cannot get it to duplicate any issues. The original diagnosis was that we had a loose ground connection at the battery. The battery, alternator, and starter were all diagnosed as in perfect working order. The tech tightened the loose ground, but the issue has not been resolved. There were zero warnings that there was an issue with the start/stop function.

The vehicle failed to re-start after being engine had been at full operating temperature then was turned off for a short period of time. It has also struggled to re-start with auto start/stop leaving the vehicle partially in a busy intersection without any engine power until it successfully turned over several seconds after releasing the brake pedal. The dealer is unable to replicate. They have tested the starter and battery and confirmed both test good at ambient temperatures. No warning lamps. Once the vehicle cools, it is able to re-start again.

The vehicle has an automatic stop/start feature that is enabled by default, though there is a button readily accessible to deactivate the function easily ea. time the vehicle is operated. The vehicle has just had the starter replaced under warranty @ 25K miles. There have been issues with the vehicle struggling to start for at least six months now - rough, slow starts where the engine is struggling to turn over. If I forget to turn off the auto-start/stop function, the engine will sometimes shut off at a red light - but it won't turn on again when the light turns green and it's time to move. I have had this happen a handful of times in traffic - the engine turns off and will not restart when normal procedures are followed.

While driving in normal traffic, when I come to a complete stop and keep my foot on the brake, the Auto Idle Stop system activates as designed. However, when I release the brake to continue driving, the engine intermittently fails to restart properly. Instead, it repeatedly attempts to restart, cycling on and off several times before shutting down completely. When this occurs, the vehicle becomes disabled in traffic and does not respond as expected. It can take multiple attempts and a significant amount of time before the engine finally restarts, leaving me stranded in intersections or in moving traffic. This creates a serious safety hazard because surrounding vehicles continue moving while my vehicle is unable to move. This problem has occurred multiple times under normal driving conditions and is not an isolated incident. During one occurrence, the vehicle failed to restart after the Auto Idle Stop system activated, leaving my vehicle disabled in traffic. As a result of this incident, my vehicle was involved in a collision that **damaged the front and back bumper**. Fortunately, no one was seriously injured, but the incident clearly demonstrates the significant safety risk associated with this defect. The vehicle is currently at an authorized Honda dealership for diagnosis and repair. I am submitting this complaint because a vehicle that unexpectedly shuts down and fails to restart after Auto Idle Stop activation presents a serious safety hazard. I am concerned that this defect could lead to additional crashes, property damage, or serious injuries if it is not corrected.

Incident

Jun 22, 2025

After stopping at a red light behind a few cars in a left turn lane, the Auto Idle Stop (AIS) system turned off the engine. A moment later the light turned green and I let my foot up from the brake pedal. The engine failed to start. The hazard lights turned on automatically. I reapplied pressure to the brake and pressed the Engine Start/Stop button, which had no effect. Electrical systems remained active (i.e. the car did not turn off completely), but the engine also didn't start. I ensured the vehicle was in park and stepped out to verify the fuel door was closed (I had just filled the tank) and check the battery connections. Cars were going around us on the passenger side, and oncoming traffic was very close to me on the driver's side. I was concerned for myself and my passengers. No one was injured, nor was there a collision. After returning to the driver's seat, I tried the Engine Start/Stop button again. This time the car shut down. I waited a minute, then started the car. The engine started successfully. The vehicle is available for inspection. The problem has not been reproduced. We have been disabling AIS since the incident, so it's unlikely to happen again. The problem has not been confirmed by a dealer or service center, nor has it been inspected by anyone yet. I noticed the engine being slightly slower to restart after AIS stopped it in the few weeks leading up to the incident. There were no other symptoms I noticed.

The auto idle stop on this specific vehicle has left me stopped in traffic numerous times. If left on, it frequently will cause the car to turn off when attempting to start from a stop at a intersection, causing a back up or near collision in some instances. It takes 5 - 10 seconds minimum to recognize what has happened, shift to park (if the vehicles allows, which sometimes does not), and restart the car. This being said, I have other Honda's with the same function, and all work normally (as expected), turning off the car when stopped briefly, and starting immediately upon letting off the brake or pushing the gas. -It's only this 2024 Odyssey with this issue- I have spoken with other owners of the same year model and have had the same complaint. The mechanics at the dealership have even said that it is a known issue with this model year, but that Honda has not fixed. This vehicle has been to the delearship at least 3 times to attempt to fix. A new battery was also not a solution. The issue continued after replacement.

When driving with or without the cruise the word BRAKE appears and the van taps it breaks automatically even when there is no reason to do so. There is no vehicle in front or anything on the road to be detected. It occasionally happens when there is a vehicle in the oncoming lane, but happens more often when there are no other vehicles close enough to be detected or cause me to need to slow down. It has been happening for some time now, but I did not know how to report it.
