The Auto-Idle Engine system malfunctions constantly. For example, several times I almost got into dangerous or possibly fatal accidents- I was in stop and go traffic on an interstate. Traffic slowed to a stop. I held the brake. The engine idled. I took my foot off the break and moved it to the gas when the traffic abruptly restarted. The car stalled and shut down. The cars around me expected me to go and had to swerve around me while I desperately tried to restart. There is no way to set a default that the auto idle feature is off when I start the car. I have to remember to turn it off. This also happened at an on ramp with a stop light, I almost got rammed by the car behind me. This feature is a drain on the engine and battery and is dangerous when it is not working correctly. The default should be off or just not have it at all. Honda dealerships aren-??t willing to help me.

?I have a concerning noise from my car's engine that I-??ve already brought in for diagnosis. Knocking/ticking/rattling noise on stand-still acceleration at relatively low speeds/under light load. Does not duplicate when revving in park, only under light load. Sound present with HVAC on or off. Does not make noise when cold or after long trips. Honda seems to be aware of this issue and has remedied it through work involving the crankshaft bearings and possibly other components as it relates to their service bulletin 23-097. The problem is that my vehicle falls outside of the stated range of production years as mine is a 2020 model year, but the likelihood seems quite high that the engine in my vehicle is suffering from this exact problem. The service department refuses to help me and the corporate line I've contacted through email me simply refers me to the service department. I just spent $38,000 on this vehicle with 30,000 miles and I have no other recourse at this point to remedy this.

The auto idle feature cuts out the engine in stop and go traffic and will not restart. This has happened on numerous occasions, creating unsafe conditions for traffic.

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.

While stopped in preparation to make a left turn across traffic on a 4 lane road, our 2020 Honda Odyssey engine stalled- the engine idle stop function did not restart the engine as designed. We had to restart our car, but the car did not immediately restart, it took us 2-3 attempts. There was no prior warning or indication there was a problem. We could have easily been hit by another car, injuring my wife and children. Our system is available for inspection, we have not had it inspected yet.

My vehicle has the engine idle option and shuts the engine off when idle in traffic or at traffic lights, etc. There have been incidents where the engine doesn't just shut off but it powers off the entire car and doesn't want to turn back on. My battery is fine because i just had service done on it and they tested the battery and its 100% fine. This issue is not a battery issue for my car. I literally had PTSD when the car shut off though because it happened at a location on the roadway where i had previously been rear ended in another vehicle and after my car shut off this time - my anxiety was very high that day and i was literally shaking. I was scared not knowing what was wrong with my car.

Vehicle driver side sliding door has issues closing. Mentioned to dealer, but dealer dismisses it as possibly from water residue after car washes. Door needs to be manually closed with pressure to latch. Vehicle has lost all electrical function while in Economy mode while in idle mode while at red lights and also while parked with accessories running. Vehicle batter life was verified and in excellent condition at battery replacement shop.

When the car engages the Idle Stop feature and shuts the engine off, the engine does not restart immediately once the brake is released. This has happened multiple times but the last time a message appeared that said to change gears and restart the car. In the meantime the vehicle was in traffic and stopped for over a minute before it could be restarted. This put us in danger of a rear end collision as other cars were wanting to go.

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.

1)The back hatch will randomly close. The first time it happened I didn-??t know what was going on and it hit me in the head. Today my kids were there and it almost hit them but I pushed them out of the way because I knew what was happening as it makes a certain noise first. 2)It stalls out randomly at red lights. 3) the doors won-??t open or close at times. 4) the dvd player gets so hot it almost burns you and the dvd player won-??t work. When I contact the dealer they say they can-??t do anything since it happens randomly and it if doesn-??t happen when it-??s at the dealership they don-??t know what to do so they don-??t even make an appointment. Two years ago we complained that the door didn-??t have a sensor because it shut my two year olds hand in the door. Honda acted like we were crazy. Then it became a recall and they -??fixed-?? them. But now they won-??t open or close.

Vehicle-??s -??Engine Idle Stop-?? feature malfunctions unless it is turned off manually. This is an energy conservation feature which turns off the engine when stopped. However, when lifting the brake, the engine does not turn back on at times, sometimes fully stalling the vehicle. At times, numerous lights have come onto the dashboard after this happens. At other times, the vehicle has completely turned off, leaving the safety of the driver and passengers at risk, particularly at stop lights, stop signs, and when in stop and go traffic. I-??m continually worried someone is going to rear-end us when they see our brake light go off at an intersection. Vehicle has been brought to Honda dealership who stated they did not know the cause and replaced the battery. Problem was not solved and continues to happen.

Sometimes (no discernible pattern) after stopping at a red light or a stop sign, the car shuts off and will not restart for several minutes. The Honda service center at the dealer where we leased the car said they have heard of similar problems with newer model Honda Odyssey and Honda Pilot but there has been no formal recall. This is a clear safety hazard. The battery has been tested and it is fine.the mechanics cannot find anything wrong with the car.

Auto shutoff feature regularly fails when attempting to restart the engine. It may delay the restart or put the car in park and not allow it to restart for over 30 seconds. I was stuck in stop and go rush hour traffic. The engine would not restart, leaving the car stranded in the center lane for over a minute while attempting to get the car to start and in drive.

Auto engine idle shut off issue and yes it is available for inspection. Upon exiting stop/start events(auto shut off at stop signs/lights/parking lots), engine does not restart. instead, it shifts into park, lights up all instruments on display panel, and requires a manual restart. vehicle is dead until restarted, posing a hazard to occupants/oncoming traffic. This has happened to me 3 times over the last two weeks. Didn't document date of 1st incident. 2nd incident was 3/22/23. 3rd incident was 3/25/2023. Immediately taken to dealer service center for repair. Dealer told us they couldn-??t replicate the issue, that there are no codes, and no service advisories. We were told there was nothing they could do and to just turn off the feature when driving. The only one to inspect the vehicle was the dealer service center. No warning at all. Car just doesn't start and driver is left sitting and helpless in active traffic until the car can be restarted.

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.

Several times the van has failed to restart from an idle stop/start at a red light and in the middle of stopped traffic. Several attempts to restart the van fail (van doesn-??t even try to start) normally after a few minutes with the van back in park it will start again. Very dangerous to be frequently left stranded in the middle of the road. Frequently when the van does successfully take off from a idle stop, you can tell it struggles and just barely is able to resume.
