I stopped at a red light and then my car just stopped. It seemed the car wasn’t able to start up the engine from the idle mode. I had to restart the car at the intersection with a truck behind me and with 3 kids under the age of [xxx] on the car with me.

When pressing the accelerator, there is an extremely loud and abnormal noise coming from the fuel pump. The noise is so severe that it raises safety concerns while driving. The issue appears similar to fuel-pump–related problems reported in other recalled Honda vehicles.
My car went completely dead while stopped in traffic on a busy street. My kids were in the car and thankfully I was able to crank it by pressing the start button. This issue has already been “fixed” and the dealership “cannot replicate”.
My vehicle was at the dealer for service in March of 2025. At that time they performed recall 23-008 although the vehicle did not have issues with the idle stop system. Since some time in June, at multiple occasions, the vehicle shifted to park on its own when restarting from idle stop. Last night, the vehicle fully shut off and lost all electrical power when restarting from idle stop leaving me stranded in the dark at a busy intersection without the ability to turn on my hazard lights. The vehicle repowered after a few minutes. When the system restarted, the info-tainment system activated the anti theft software which happens during full power loss.
Subject: urgent vehicle safety concern – sudden malfunction and safety risk on [xxx], at approximately [xxx, I experienced a traumatic incident when my vehicle unexpectedly malfunctioned while I was driving home. After making a left turn on a green signal from [xxx] toward the community, the car suddenly stalled. By god's grace, I managed to cross woodbridge avenue before stopping, avoiding a major traffic obstruction. However, it came to a complete stop in the middle of the street, creating a hazardous situation. After a brief pause, the car moved approximately 10 yards before stopping again, becoming completely immobile in the middle of a public road. Attempts to jump-start the battery failed. All warning lights turned on, but the engine would not start. The vehicle could not be restarted or moved under its own power. 911 was called, and police responded promptly to the scene. With the assistance of my wife, police officers, and local neighbors, a tow company was called to remove the vehicle from the roadway. It was then towed and parked in a nearby lot. This incident was highly traumatic and posed a serious threat to my safety, my family's safety, and the safety of the public. Diagnostics and expert assessments indicate the issue may be related to a manufacturer defect, which is deeply concerning given that this is a new vehicle. At this time, the vehicle is no longer drivable. I am seeking urgent assistance to resolve this matter with the manufacturer and to ensure that other consumers are not exposed to similar risks.

The idle start stop feature constantly doesn’t work. When stopped at a light or stop sign the engine will turn off and when I release the break it is supposed to reengage the engine. Instead it stalls out causing me to have to put the car in park and restart the car. There have been several incidents where this is during rush hour traffic causing traffic jams. Sometimes I have to wait a few minutes before it will actually turn over. The car is 5 years old and I have had the replace the battery twice and I have been told that this feature puts a lot of pressure on the battery. Never can the dealership recreate the issue.
Fuel pump quit working while driving and caused my vehicle to stop in the middle of the road. My vehicle had 63000 miles when it stopped working.
Car stuttered and completely stopped running on the road. Cops had to come and direct traffic around me while my car had stopped. Towed the car to the dealership and the fuel pump was identified as the problem. Car has 63000 miles on it.
Idle stop caused engine to stall 3 separate times leaving me stranded in busy intersections making it difficult to restart vehicle and move safely out of the way. Initial start up checks come on, asked to put car in park, step on brake to restart car, car won’t restart. Once happened at night and shut off all my lights for 30 seconds making me not visible for cars coming up to me.
The car stalled when stopped at a red traffic light. This happened on 2 occasions, 11-3-23 and 12-9-23. The second time other cars behind us had to go around us while we tried to restart the car which put them at risk of being hit by cars in the other lanes. There was no warning. I took the car in for regular maintenance a few days ago during which the dealership did a multi point inspection but did not discuss this issue. Yesterday I heard about the fuel pump recall and think this might be the same issue. I called the dealership today but they said our car is not under the recall. Our car is available for inspection upon request.
9/29/23 vehicle left my wife stranded on in parking lot would not start. Had vehicle towed to garage. Garage had to replace the fuel pump as the impellers were no longer working. Vehicle would not turn over acted like bad gas, shop put in fresh gas still would not start. Found failed fuel pump. 1/04/24 called Honda 888-234-2138, rf teh 12/23/2023 recall on additional 2. 8 mil units including my Odyssey. Spoke to angel at Honda, he told me my unit was the only one out of millions of units not affected by this recall, even though my wife was left stranded in a parking lot. I have the invoice but your system will not allow me to upload anything. . Read more...
At a stop light the engine idle shutoff feature shut off the engine. Then a few moments later the entire vehicle shut off. I could not turn the vehicle back on after trying several times to do so. After about five attempts the vehicle turned back on in park gear. During this time the light turned green and the vehicle would not turn on, cars behind began honking. This has happened a few times since owning the vehicle. I was dead in the middle of a busy intersection. I have asked the dealer to look at the electrical system as there have been several anomalies but it checks out fine. I replaced the battery thinking that might be the problem but did not work. I believe it is the same problem as pe22005.
On at least 5 occasions the car has not restarted after going into auto idle while stopped. Normally after pressing the brake pedal all the way down while stopped, the engine will shut off and then restart after releasing pressure from the brake pedal. When it doesn't restart, all the lights on the dashboard come on and you can't do anything. It won't restart if your press the start button and you can't shift it to neutral to push it out of the road. Eventually it will restart by pressing the start button. I have not had this problem if I turn off the auto idle, however you have to manually turn off the auto idle every time you restart the car.
The idle stop caused my car to turn off on the highway while I was stopped in traffic. Unfortunately, I was the last car in the line on the highway and the truck coming behind me was coming at a rapid rate of speed. Thankfully, the same issue had happened to my son the week before and he was able to tell me that putting the car in park and turning it off and back on would fix the issue. There is a service bulletin 21-013 related to this issue but not a recall. This is a safety issue that needs to be addressed.
Not sure about which component failed and put my family and I in significant danger. We had just come to a stop at a traffic light at the end of a highway exit ramp when the car shut off without warning. Completely off. Hazard lights didn’t even work. Nothing worked. Took a minute or two until the vehicle restarted as if nothing had happened. Cars were coming up fast behind us and had to move quickly to get around us. This was late at night so we were hard to spot without any working lights. Thank the lord no one was injured. I suspect it has something to do with the idle-stop feature. This incident happened within the last 2 hours so it hasn’t been reproduced or confirmed by a service center. Please require Honda into issue a recall for whatever caused this defect.
The signal turned red, as I was braking, the car engine stuttered and car shut off. Startled, push the park button, and pressed the engine start button but no response, pressed again and it started. This happened 6 months before but didn't report it as I thought it was a once off event. 6 months ago, the car was at a red light, the idle was on and when I accelerated cause the light changed green, the car shut off. Get the feeling its due to the idle but wanted to report this matter.
New ex-l model van with about 800 miles on it began to permeate the cabin with a gaseous odor coming from the air vents in recirculate mode and could be smelled from the outside of the vehicle as well. Initially smelled it when at idle after a 150 mile one-way trip. The vehicle had to be turned off to make the smell stop. It started again upon return and got stronger when the a/c was put in fresh air mode.
