Honda Odyssey 2024 — Reported problems

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.

I am submitting this complaint regarding a serious safety issue with my Honda's Auto Idle Stop/Start system. On multiple occasions, while stopped in traffic or at an intersection, the Auto Idle Stop system has automatically shut off the engine as designed. However, when I release the brake and attempt to proceed, the engine fails to restart. The vehicle becomes stalled and immobilized in the middle of active traffic. I have been stuck at traffic intersections because of this failure, creating a significant safety concern. When the vehicle fails to restart, surrounding traffic expects the vehicle to move when the light changes, while I am unable to accelerate or safely clear the intersection. This creates a risk of a collision, particularly from vehicles approaching from behind.

Today 09/24/2026 while stopped at a traffic light the car lost all electrical power and blacked out while in auto-idle stop. Last week while driving the middle electrical screen went dark. After a few minutes while driving the H symbol appeared on the display and the screen reloaded.

The infotainment screen just went blank. No phone, radio, backup camera works. The car runs fine. Tried to reset and unplug the battery but did not fix the problem. Van is still under warranty taking it in for diagnostic.

My vehicle automatically shut off at a stop light and instead of turning back on, it died and left me stuck in traffic. I purchased the vehicle from a dealer on 9/11/2026 and this first happened 9/14/2026, and again on 9/18/2026. Both times my automatic shut off was automatically on and both times I was at a stop light where the automatic shut off engaged and instead of turning back on- my Van died at the light. Both times I was stuck in traffic.

The vehicle's Auto Idle Stop (AIS) system failed to restart the engine after engaging at a complete stop. The affected components are the engine, starter motor, and AIS control software. The vehicle is available for inspection upon request. On XXX, at approximately 7:43 PM, the AIS system engaged while I was stopped at the intersection of [XXX]. Upon releasing the brake pedal, the engine failed to restart. The vehicle became fully immobilized in an active left-turn lane with traffic behind me. I was required to shift to Park and manually depress the Start button multiple times to restore power. Multiple vehicles behind me began sounding their horns. A minor child was a passenger in the vehicle. This is not an isolated incident. The vehicle has been presented to Howdy Honda, in Austin, Texas, for the same defect on three to four prior occasions. On the most recent prior visit, the dealer replaced the starter motor — the specific remedy prescribed by Honda Technical Service Bulletins 23-008 and 23-009. The vehicle was returned to me as repaired. The failure recurred the same day. The defect has been confirmed and repair attempted by the authorized Honda dealership. The manufacturer has been on notice of this defect class-wide since at least 2018. Prior to and during failure events, the instrument cluster displays a Red Exclamation Mark warning light and/or a "Brake System" warning light. These warnings first appeared in conjunction with the initial AIS failure events and recur with each subsequent incident.

While the idle stop system was active, the vehicle turned off while stopped at a red light as expected. After the light turned green, the vehicle did not restart and turned all the way off and then attempted to reboot. I had to push the on button to turn the car back on. The first three attempts to start the vehicle resulted in clicking sounds like a dead battery. This has reoccurred at least 4 times in the past couple weeks and has only occurred while restarting with idle-stop and not when starting for the first time. I’m concerned I will get rear ended while I have my little kids if it doesn’t restart.

My 2024 Honda Odyssey has repeatedly failed to restart after the Auto Idle Stop system shuts the engine off while stopped at a red light or in traffic. Normally, the engine should automatically restart when I release the brake, but on several occasions the vehicle completely shut down and I had to manually restart it. During one incident, the vehicle would not restart for approximately 1–2 minutes despite repeated attempts. This left the vehicle disabled in traffic and created a serious safety concern. The problem has occurred multiple times.

My vehicle has approximately 12,000 miles and on 9/7/26 and 9/11/26, my vehicle would not restart at a light with the auto shut off. I had 4 small children with me on 9/7/26 and had several cars behind me aggressively honking. I could not get the car to restart for several seconds. I was finally able to turn the car completely off and get it to restart. The instance on 9/11/26 was equally as startling. After talking to a friend who has the same Honda Odyssey, she said her van was actually at the dealer with the exact same problem. The Honda dealership told her this is a “known issue” and she is having her starter replaced. I am so upset that Honda has failed to ensure the safety of a van that families rely on. I will be taking our van to the dealer next week.

When in traffic at a stop, my car goes into idle mode, and when I take my foot off the brake to switch to the accelerator the car shuts down. It takes a few tries to get the car started back up again. This has been happening intermittently for over a year.

The idle stop system was on while I was driving my car. At the stop light, it activated. When the light turned green and I took my foot off the gas, the car shut off. I had to press the ignition start button several times to get the car to start again.

The vehicle suffered an Auto Idle Stop failure at a red light. The engine shut down normally, but failed to automatically restart when the brake was released. There were no dashboard warning lights, and I was forced to manually shift the vehicle into Park to restart the engine in active traffic.

My 2024 Honda Odyssey Elite has had two recent incidents of car going into idle and won't start up. The more serious one happened while I was stopped waiting to make a left turn. The Auto Idle Stop system shut the engine off when I was waiting on. Y left turn engine did not restart. I was stuck in the roadway for about two minutes before I was able to start the vehicle again. The red battery warning light was on while the engine would not restart. A few days prior during a trip from [XXX] to [XXX] the vehicle also would not start after I had been sitting with the engine off and accessories running at a gas station. After turning off the A/C fan, rear entertainment system, and unplugging my phone, the vehicle eventually started. I took the vehicle to a Honda dealer (Honda of [XXX]) They inspected it but said they could not reproduce the problem, so no repair was made. And they refuse to use my warranty to fix it. The vehicle is available for further inspection. My main safety concern is that the Auto Idle Stop system can shut the engine off in traffic and then fail to restart, leaving the vehicle disabled in an intersection like what happened to me.

The contact owns a 2024 Honda Odyssey. The contact stated that while entering the vehicle through the rear passenger-side sliding door, the door began to close automatically while the leg of the contact's child was still outside of the vehicle. The child sustained lacerations and tendon damage to the left foot, requiring medical attention. No warning lights illuminated. A local dealer was notified of the failure, but the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 20,000.

Car fails to restart after shutting down using the idle start/stop issue

While stopped at a red light on a busy road my car engine stopped and usually it automatically restarted when I let off the gas but it would not start and the engine would not turn on. The car was stalled and it took multiple attempts to get the engine to restart. This has happened 3 times now. I have had the battery tested and the battery is good and my mechanic believes it is an issue with the starter

The van has trouble restarting. This can appear as both a sluggish restart and a complete failure to restart. The van has failed to restart both during quick stops like refueling and during the auto-stop feature at a stop light. When this happens, the driver must completely shut off the van and restart, which is a safety issue when stuck while blocking traffic. The van is having the starter replaced for a second time after the dealer determined the starter was failing. The starter was replaced in 2025 under warranty because the dealer determined the starter was failing. There are no warning lamps, but the starting does start to slow down over time. We missed the slow down the first time until it failed to restart because the onset is gradual. We only noticed the second time because we'd already encountered the issue. The two dealerships we've taken the van to for this issue were both hesitant to do the work, claiming trouble recreating the issue.

I was stopped at a stoplight. The car has idle stop so the engine turns off at the light. When I tried to go the car went into park. I could not get it back in drive and had to turn the car off then back on. Meanwhile I am stuck in the middle of the road with traffic. This has happened several times before.

Yesterday (8/21/2026) my husband took this vehicle in for a routine oil change and upon the 100 point inspection was informed there was an oil leak somewhere from the engine. This vehicle is barely 2 years old and barely at 30,000 miles. There were 0 signs of a leak somewhere we had no idea. They completed diagnostics and determined it was the axle seal. Thankfully this was covered under warranty but their master mechanic shared with my husband that this is a very well known issue with the 2024 models and the fix is using the newer manufacturing parts. Again, there were no visible signs of a leak, there were no vehicle computer warnings of an issue other than the oil life alerts that are programmed.

The Auto Idle Stop mode has caused my car to stall out at least 10 times since I bought the vehicle in August 2024. Each time it has occurred, it has taken me several minutes to restart the car. I’ve bought my vehicle to Hilton Head Honda in Bluffton, SC two times to have them inspect the vehicle. The only thing they have done is replaced the battery which has not solved the problem.

The speakers make a popping and crackling noise that is repeated, in a mid tone - high tone - low tone noise pattern, when the radio is on or off. It begins when the engine is turned on. It also occurs in standby/engine is not on/radio is on mode or in standby/engine is not on/radio is not on. The popping/crackling occurs whether the radio is on or not, and the radio can be heard along with the popping and crackling noise. I am guessing it is similar to the recall 23V-431, but this van VIN number does not have any recalls associated with it yet. Restarting the radio, resetting the radio, etc does not alleviate the issue. Also, the cabin camera is not working, says "problem with camera" and displays "loading" with the moving circular icon. The display remains dark for the cabin camera, and rear entertainment screen is also not accessible. Cannot recall any large bumps in the road, no collisions with anything. If the design of the cables has not changed, then the recall needs to cover all VINS manufactured with the same wire assemblies and procedures, including all future VINS, as this problem is clearly repeatable. The customer should not bear the burden to fix an issue that has been deemed an issue in prior year models, with no changes to the design or assembly procedure to the related components.

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.

2024 odyssey engine shut off while in drive thru at restaurant. Unshure if auto start stop override was active. Either way the van had to be re started using the start button. Van re started on second or third attempt to re start with start button. This is a repeat occurance since having starter replaced in response to a similar problem about a year ago.

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)

From a cold start my vehicle starts fine, but from a warm engine start the van would have trouble starting. Took it to Navarre Honda in Lake Charles, La and they found that the starter solenoid and 2 relays were bad and had to be replaced.

While stopped at traffic lights or in traffic, the Auto Idle Stop system activates, but the engine sometimes fails to restart when I release the brake pedal. The vehicle becomes disabled in traffic, and I have to shift the transmission into Park (P) to restart the engine.

completely shuts off during an idle stop at a traffic light

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 ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

Several times the vehicle has turned off due to the auto on/off and did not restart. No warning. This happened two times at intersection near school with multiple children in the vehicle. Vehicle was not able to restart immediately. Changed to a new agm battery and still does not work. Trouble starting. Slow starting and combined with auto on off this is a dangerous disaster of vehicle

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.

Had to replace starter at 29,000 miles due to auto stop/start prematurely wearing out component.
