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 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.

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.

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)

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.

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.
