Sometimes when the car turns off for the auto stop function at something like a stop light or stop sign it stalls when trying to restart. This requires a whole restart with getting back into park and getting the van to start again. It seems to happen most often when the air conditioning is on but not on full blast. I brought it to the dealer once and they couldn’t reproduce the issue or find something wrong. It has happened since that appointment and I am bringing it back. Some lights show up on the dash but i don’t remember which ones as I’m trying to frantically start the van again because I’m typically stalled at a stop light.
2024 Honda Odyssey electrical complaints
Page 2 of 3: complaints 11 to 40 of 60, newest first, as owners wrote them.
The vehicle came to a complete stop at a stoplight at a busy intersection and the Auto Idle Stop feature engaged. When the brake was released to resume driving, the engine struggled to restart, and then stalled completely in the middle of traffic. The vehicle did not automatically restart upon releasing the brake, and had to be placed into park, turned off completely, and then restarted manually to regain vehicle control. This has happened several times. There have also been instances where the vehicle did not stall completely, but bucked violently when the Auto Idle Stop feature restarted the vehicle.
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.
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.
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.
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.
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.

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.
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.
Car fails to restart after shutting down using the idle start/stop issue
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 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.
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.
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.
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.
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.
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 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.
Had to replace starter at 29,000 miles due to auto stop/start prematurely wearing out component.
The vehicle is experiencing an Auto Idle Stop (AIS) failure to restart from a complete stop. The engine dies, the electrical system resets, and it requires a manual button push or jumpstart to get moving again
Last week, I opened my vehicle door and noticed water standing in the foot well. I didn't think too much of it until I started driving down the street and gallons of water were gushing on my feet in the footwell from behind the steering wheel and fuse box. I parked and waited for it to dry out a few days. I took my vehicle to the dealer and was shocked to hear that this is caused because the sunroof has a drainage system, and when the primary drain clogs, due to pollen or dirt, the secondary drain drains directly into the driver footwell. They advised that this is an issue that disregards vehicle age and sunroof non-use. Because this is a new vehicle, all of my basic maintenance and inspections have been provider by the Honda dealer. I asked why this had not been inspected on my previous service appointments and was told the primary drain for the sunroof can only be inspected by camera. It is only when the primary drain becomes clogged that the water dumps into the driver side footwell. I searched my owner manual and found nothing to indicate or require that the primary sunroof drain should be inspected, cleaned or serviced, at any of the maintenance intervals, and especially not during the first 2 years of ownership. The steering column, fuse box, and driver footwell house all of the necessary electrical and mechanical parts for steering, braking, acceleration, lighting and all other electrical systems controls. Additionally, if this were to happen while driving, the distraction to the driver could be catastrophic. My vehicle has been at the dealer for a week to clear the clog in the primary sunroof drain, remove the seat and carpet to dry, & inspect the electric systems including the power seat. I can make the vehicle available for inspection as needed and the dealer can provide the camera inspection that diagnosed the issue. This happened due to everyday dust and pollen, and there was no advance warning that this drain failure was imminent.
Automatic start stop completely turns off car when pulling up to a stop sign, light, or yield intersection. Car completely turned off and wouldn’t start on a bridge overpass causing a safety hazard. Took a solid minute for it to restart.
Since purchasing my 2024 Odyssey EX-L I have experienced on multiple occasions where the idle stop engages but upon releasing the brake the vehicle fails to restart, dash lights up and vehicle is shifted automatically into park while sitting in traffic and vehicles moving all around me as well as honking as I am unable to restart the vehicle immediately. I have to push the start button multiple times before the vehicle will restart. Dealership is unable to replicate issue so I just started turning it off. Now the idle stop/start doesn't engage at all even after driving for hours. Additionally the vehicle is very slow to start especially if I have had to start the vehicle a different times throughout the day. I took the vehicle back to the dealer and they diagnosed it with a bad starter at only 38K miles which is of course out of warranty. Not only is this a safety issue of the vehicle stalling in traffic but Honda is failing to recognize a well known issue with the starter in this particular vehicle, sticking consumers with hefty repair bills for a manufacturing issue.
For the past year, the vehicle's Auto Idle Stop system has intermittently failed to restart the engine after coming to a complete stop at traffic lights. This creates a dangerous situation where the vehicle is immobilized in active traffic, posing a significant risk of rear-end collisions or other accidents. I have taken the vehicle to an authorized Honda dealership for service; however, they were unable to duplicate the issue and declined to perform further repairs. As the problem remains unresolved, I am reporting this incident to the federal safety agency to contribute to the official record of safety concerns regarding this feature in Honda vehicles.
My 2024 Honda Odyssey EX-L has a recurring Auto Idle Stop failure. About 1–2 times per week, when stopped at a light and Auto Idle Stop engages, the engine fails to restart properly when I release the brake. The engine sputters or shuts down, the battery warning light comes on, and the vehicle shifts itself into Park. I then have to hold the start button for several seconds to restart the engine. This creates a safety risk because the vehicle becomes disabled in active traffic when the light turns green. The vehicle was previously taken to a Honda dealer for this issue, and the battery was replaced, but the problem continues.
