1. I believe the Auto Idle Stop - the vehicle stopped at a red light not warning it stalled and would not start again. 2. Safety was impacted as my children and I were in the car in the middle of traffic and we had to exit the car across 4 lanes of traffic. Called non emergency # for police to park behind the car so that it did cause an accident with traffic. Called AAA and they towed the vehicle home. 3. AAA tested battery it is good, alternator is good, took it to Midas for an overall diagnostics check and they did not find anything wrong or any errors recorded. 4. No warning lamps, messages or symbols till after it stalled and it showed the battery light.

Won't start by model year
What owners say
The vehicle won't start, electrical system failure. Sometimes the electrical system fails when the car is driving/it will stall on the road. It was predicated by the alarm going off intermittently and without provocation (in the middle of the night/etc).
auto idle stop stalled at a red light causing my car to not move and having to shut off my car in the middle of traffic. Once i tried to turn back on it wouldnt start at first. i had to do this twice in order for the car to come back on.
The Honda Pilot completely lost power on my husband's way home from work in a snow storm. It would not start but it did yesterday. It sounds like clinking/clunking when started but stalls out if you try to put it in drive or reverse. It has a brand new battery. But otherwise it had to be towed and is now sitting. It didnt give any warning signs or lights on the dash until after it completely broke down. It has the engine light on when started. It has not be confirmed by a dealership as times are really rough right now with a new baby and not having the extra funds to have it looked at. And not to mention the closet dealership to look at it is almost an hour away. It seems that the rods/engine area are at fault.
While driving the check engine light started flashing and lost a lot of power. Pulled over and turned the car off. Turned the car back on and the light was gone and power seemed to be back. Trying to get home about 15 minutes later every light came on. Lane assist, check engine, blind spot, traction control, literally all warning lights. When these came on the car lost all power within a minute. Wouldn't turn over or even power on to use lights or the radio. Got the car towed to two separate garages both stating engine failure. Honda dealer provided documentation of a bearing failure which damaged cylinder 5.
While driving on the freeway at a slow speed due to two freeways merging, my Honda Pilot suddenly stopped/stalled. When I tried to restart the car by pressing the Auto Idle Stop button to vehicle did not start. It took three times of pressing the Auto Idle Stop button for the engine to restart. I am lucky that the traffic was going at a slow speed due to the merging of freeways so I was able to right away press my emergency signal lights on. I panicked and was scared for my safety and what could have happened to myself and others if the vehicle was running at a higher speed. This could have caused a major accident. Because this happened yesterday, I will be calling Honda to report the issue as well and have my vehicle inspected. My vehicle has had issues many times in the past with the Auto Idle Stop button not starting, however, it has never happened while driving. The concerning part as well is that the vehicle did not give any kind of warning light or message.
Car is slow to start or doesn't start at all, particularly after frequent engine stops/starts or when engine has idled for a period of time. Battery has been replaced. Symptom comes and goes, but seems to get worse with frequent engine stops/starts (i.e., driving to different locations with short stays at each, or with the automatic engine shut off)
AFTER I had the softwear update! When idle at stoplight, auto idle feature kicked on. When light turn green and I pushed gas, car shut off entirely. This happened on multiple occasions. While waiting for an appointment to get this issue looked at, my car failed to start after being parked. It would not start after a jump from another vehicle. The tow truck driver was able to bet it jumped using a battery pack case. At the dealership, battery failed load test. Waiting to see if starter needs to be replaced and valves adjusted under extended warranty.
Vehicle when trying to start locks up, have had the battery alternator starter checked, changed the brake switch and still having issues with hard start to my 2021 Honda Pilot. When this happens all the lights come on. I push the Idle/Start switch when I do get it started so that it does shut off when I’m at a red light or stop sign. Because I’m afraid it will not start. Dealership could not find any issues with the vehicle, I’ve taken it to another mechanic and they could not. It has been put on diagnostics several times. I keep putting money into trying to find out what the issue is!!!
The auto idle-stop feature in my Honda Pilot prevented from starting the engine again. It is available for inspection upon request. I was at the stop light with the idle-stop feature enabled and when it was time for me to start driving again, the car would not start. The car turned off completely and a lot of the lights including the battery light turned on and a message stating to bring the key fob close to the start button came on. The battery has been changed within a year since I mentioned this problem to the dealership when I brought it in for an oil change. They determined that they had to change the battery. Clearly this did not solve the issue. When this happened today, I was driving on [XXX] which is a highway with a lot of traffic. Since I was unable to move forward, I backed up the traffic coming behind me. The problem has not been produced or confirmed by the dealer since this happened today. The component has not been inspected by the manufacturer even though I have brought it up to their attention, police, or insurance representatives. No warning lamps, messages or other symptoms of the problem prior to the failure have appeared. This is the first time that the car has completely failed to re-start. In the past, it has struggled to start, but it makes it happen. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
My push start is not starting the car. Then while driving the car will shut off on parkway, at a light and won't start. This has been going on since I purchased the vehicle 9/23 I have warranty and th auto dealership keep acting like they fixed it yet the haven't. This is the most dangerous issue. We can die getting hit from behind or the car can catch fire keep pushing start button and not turning on
On two occasions my car has stalled out and would not start. The engine turns over but it seems to not be getting fuel. There is still a quarter of a tank of gas in the car. After adding additional fuel and clearing the code P0087. The car runs. I brought the car to the dealership but they said there were no codes and there is nothing they can do. There are recalls for fuel related problems on Honda Pilots 2015-2020 this was issued 12/17/2023. There was a more recent recall on Honda Pilots 2022-2025 for fuel related problems on 1/22/2025. My Pilot is a 2021 the only Pilot not recalled in the past 10 years for fuel related issues. Please recall the 2021 Pilot. I tried reaching out to American Honda and they were no help. They told me they do the recalls and to reach out to you. Please help I am afraid the car will stall out at high speeds and cause harm to me and my family
