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.

The vehicle is currenting having an issue with the MOST feature which is causing a static sound coming from the speakers as well as the DVD/CD player not working at all. Once in a while when idling with brake on the vehicle will shut and down and restart on its on quickly. When this happens multiple warnings will appear on the dashes warning system. Some of these warnings are mitigation collision warning, cruise control, and low power.

Car was stopped in traffic and has a feature that shuts off the engine when stopped (in Drive but with brakes pressed). When trying to proceed forward car shuts down with numerous errors and does not start back up for 5 minutes. Cars are honking and having to drive around us. Eventually was able to get the car running and moved to a safe area. Errors car displayed included: blind spot info system problem and transmission problem

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.

Start stop system malfunctions during auto stop/restart. Van will stall or fully turn off instead of restart when brake released and accelerator pressed. Problem is intermittent and increasing in frequency. This results in unexpected stalls/stops in traffic, putting driver and passengers (as well as other vehicles) at risk. Message displayed is -€œCollision mitigation system problem-€ or the van stops itself and tells the driver to -€œshift to park-€. Van may or may not immediately respond to starting push button. Dealership cannot identify problem, but numerous other customers report similar complaints.

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

The -€œauto engine idle stop-€ system in my minivan is malfunctioning. This is a safety issue because the engine does not always restart when I take my foot off the brake. I am eventually going to be hit from behind by a driver behind me that assumes my minivan will accelerate from a stop when it is supposed to. Every time the malfunction occurs, the dashboard displays a message -€œCollision Mitigation System Problem-€. However, I have been told by the dealership mechanics that this message is erroneous and that it is displaying because there isn-€™t a preset error message associated with the auto-engine idle stop malfunction. My minivan was 2 years old when I brought it to the dealership for repair the first time. That was in October-2021 and the dealership is Honda on Grand in Elmhurst, Illinois. I brought the vehicle to them on seven different occasions between October-2021 and now. Even though they were able to reproduce the problem, they say they don-€™t know how to fix it. So, they made minor repairs each time to different electrical and drive train systems in hopes that the malfunction will cease. After 10 months and 7 attempted repairs, my vehicle is still malfunctioning. The dealership instructed me to contact the corporate level Honda Customer Service Department, which I did on July 8, 2022. I was issued a case number and a customer service representative, Walter, to assist in resolving this problem. After many follow-up phone calls to them, they will not return my call to discuss my vehicle. I recently contacted the Elmhurst, IL dealership and spoke with the service manager, David Abraham, who said he would follow up with Walter. However, I still have not been contacted. I am very concerned for my safety and the safety of my two teenage children who are now driving my vehicle. This will undoubtedly lead to a collision if not repaired.

My 2020 Honda Odyssey the engine stalled while I am driving. It isn-€™t the first time in part two years. My first complaint to the dealer on 2020, the first time my engine stalled when I was moving to the Parking. The engine stalled and all the lights on on the dashboard with a big bang sound. I restarted the car and my car can drive again. I bought it to the honda dealer at puente hills and they told me stop to use the brake hold system while I am driving. After a few weeks later, I have the Same problem again when I made a right turn. After the turn, my car engine stalled again and I almost got rear end from the car behind me. I needed to restarted my car to drive again. After that I drove to other honda dealer at West Covina to check my car and they was unable to find any problems. They told me to take videos when the happenings again. My car was fine for almost two years. My car engine stalled again while I was driving also with the Big Bang sound and all the light on on the dashboard. But I don-€™t need to restart my car on this time.because the engine start again after all the lights off from the dashboard. I just need to pass the drive button to move my car. I feel so dangerous. I bought my car honda dealer to check and they told me my throttle have carbon buildup so I paid for them to do it. But I am still feeling unsafe and it-€™s a unacceptable situation.

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.
