My 2024 Honda Odyssey ex-l has a recurring auto idle stop failure. About 1–2 times per week, when stopped at a light and auto idle stop engages, the engine fails to restart properly when I release the brake. The engine sputters or shuts down, the battery warning light comes on, and the vehicle shifts itself into park. I then have to hold the start button for several seconds to restart the engine. This creates a safety risk because the vehicle becomes disabled in active traffic when the light turns green. The vehicle was previously taken to a Honda dealer for this issue, and the battery was replaced, but the problem continues.
I have had multiple issues with the radio (16000 miles). After many personal videos dealership was able to fix one of this issues with a new part (22000 miles). I was informed the other issues I was having with the radio was due to my battery not staying fully charged. I was also having issues with the van not starting right away, which made me feel I could get stranded. It took many attempts to get the van to start. The van also wouldn't let me reverse one time, with a message telling me to place van in park. Another issue is the van is very slow to restart from auto idle shut off. The transmission is slow to change gears in lower gears and the van jerks a little bit. Next my rotors were warped. I was informed by the dealership that there was nothing wrong with my transmission and the auto idle down was working properly. No one could explain the rotors being warped. They reshaped my rotors and replaced the battery and told me they hoped that fixed the problem. Well indeed it did not fix the problem. As of 12/27/25 the van completely shut off at a stop sign and again on 12/28/25. The issue is only getting worse (24,000 miles) and now I am scared to death that the van will stop while I am driving. The dealership has been contacted and I am waiting on a call back for a loaner car. I was in traffic and was extremely worried about my safety, as well, the safety of others around me and with me. ( side note I returned the van to another dealership soon after the first dealership performed work on the van, when I heard a metal on metal sound and what sounded like a bolt rolling around in my back brakes. They did not find anything wrong but were also puzzled by the rotors already being warped. I was afraid to make the trip to the orig dealership). I have recently gotten a video of the brakes scraping again. This van is causing a lot of safety issues for my family.
The start stop system has failed to restart at a busy traffic light more than half a dozen different times after a 1 hour drive. Short drives do not bring this issue out. This got me stuck at a light, drivers annoyed honking and confused as I try to get my vehicle to start again. Turning the van completely off and back on again seems to get the van to restart again. I tried bring the issue up to the dealer when I brought it in for its first service, but the employee was extremely rude/belligerent and stated they would only do an oil change when I asked for help with this safety issue among other things. Will take to another dealer next service interval and try again. No issues known or warning lights on the vehicle prior. The van when it did this, error'd stating failure to restart or something along those lines. It happened so fast I don't 100% recall. After the issue the van would have no issues or lights on at all to even think anything had went wrong in the first place. This is a 2024, purchased new, vehicle.
Transmission has hard shifts in lower gears. Causing the car to jump/jerk wich could cause driver to possibly loose control in wet road conditions.
For the past year, the vehicle's auto idle stop system has intermittently failed to restart the engine after coming to a complete stop at traffic lights. This creates a dangerous situation where the vehicle is immobilized in active traffic, posing a significant risk of rear-end collisions or other accidents. I have taken the vehicle to an authorized Honda dealership for service; however, they were unable to duplicate the issue and declined to perform further repairs. As the problem remains unresolved, I am reporting this incident to the NHTSA to contribute to the official record of safety concerns regarding this feature in Honda vehicles.
My car is experiencing the starting issue that is listed as auto start/stop feature. However, since I almost always have the ac on or start/stop disabled because the car will not start when hot after a few stops and was scared it would do it in traffic. So far I can get it started again but need to completely turn car off and try again, sometimes more than once. Had been going on for a year and the dealer has replaced battery then the next services said nothing wrong. Now the car is out of warranty and the starting issues getting worse and have finally found online that others are experiencing similar issues. I have forgotten to turn off start/stop a couple times and been stranded in traffic as well when car auto stopped at red light and did not restart causing me to be stuck until I could get it restarted.
