When the automatic start/stop feature turns the car off when the brake is fully depressed the Car will sometimes not restart as designed. Further, it is sometimes accompanied by the forward collision warning light coming on and shutting the car off.

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 -??Collision mitigation system problem-?? or the van stops itself and tells the driver to -??shift 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 -??auto 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 -??Collision 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.
