2021 Honda Pilot ELECTRICAL SYSTEM,ENGINE

Car does not want to start even though the batter and alternator are good (tested by tow truck company). Restarts fine once batter is disconnected and then reconnected again. This has now happened twice.

While stopped at an intersection, the car died, the transmission shifted to neutral automatically and the radio would not turn on. The AGM battery was replaced approximately one year ago when a similar situation took place.

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.

The Auto Idle Stop (AIS) feature on my 2021 Honda Pilot intermittently causes the engine to shut off at a stop and fail to restart. When this happens the vehicle remains completely unresponsive until I shift into Park and manually restart the engine.This has happened multiple times in traffic and at intersections, creating a huge safety risk. I have already replaced the battery and had the latest software update installed at my local Honda dealership, but the issue persists. The problem is intermittent and difficult for the dealership to replicate. The auto idle stop issue is a known problem with Honda even extending a warranty coverage for the starter assembly and starter relays. The NHTSA number EA25004 addresses this yet the local dealership will only update the software and change the battery. They are failing to honor the second stage of the repair calling out specifically replacing the starter assembly, starter relays and adjusting the valves.

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)

The contact owns a 2021 Honda Pilot. The contact stated that while at a complete stop with the START/STOP feature activated, the engine shut off while depressing the accelerator pedal. There was no warning light illuminated. After waiting for several minutes, the contact had to perform several procedures to restart the vehicle. The vehicle was initially taken to a dealer where a software update was performed; however, the failure returned weekly. Recently, the contact stated that upon restarting the vehicle after the failure, the vehicle began to jerk while accelerating, with an abnormal tapping sound coming from the engine. The vehicle was taken to a dealer and was diagnosed with a defective engine rod bearing. The contact was informed by the mechanic that the repair could not be warranted. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The contact was referred to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 15,000.

When stopped at a stop light the auto idle stop turned the car off. When we tried to go at the green light the car wouldn't move. The transmission shifted to neutral and was stuck. We couldn't put the car in park, we couldn't turn the car off, we couldn't put it in gear. We considered calling the police for help since we were stuck in an intersection. The car eventually turned off and we tried pushing all the buttons to do something it finally allowed us to turn the car 100% off and restart it. Then we could go.

My 2021 Honda Pilot SE FWD would not restart after the auto off/on turned my engine off at a stop light. Of course this happened at a busy intersection causing backup and an unsafe environment to get out and inspect the vehicle. The car had to be jump started by a kind individual.

Engines sometimes fails to start again after being turned off briefly. Will have so turn off all electrical and push button to start multiple times before it engine starts again

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 contact owns a 2021 Honda Pilot. The contact stated that after idling at a red light, the Auto Start failed to operate as designed. The contact had to shift to park(P), and several attempts were needed to restart the vehicle before the contact was able to continue driving. There were no warning lights illuminated. The vehicle was taken to the dealer, who diagnosed that the battery had failed and needed to be replaced. The battery was replaced; however, the failure persisted. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 33,000.

The contact owns a 2021 Honda Pilot. The contact stated that while temporarily stopped at a traffic light or a stop sign, the vehicle occasionally shifted into neutral, or the vehicle shut off unintendedly. There was no warning light illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The contact was informed that the VIN was not under recall. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 68,000.

Our vehicle continues to randomly turn off and not go while driving. Whenever the idle start/stop is engaged, the vehicle will randomly not restart when traffic is moving. When this occurs you must completely turn off the vehicle, wait a few seconds, restart the vehicle, wait a few seconds, then attempt to place back into drive before being able to move. We have been having this same issue many times now. We have taken our vehicle in to the dealer service department multiple times with this issue. We have replaced the battery ($400) and it still happens. They act like they have never heard of this happening to anyone before and we must be "making it up". They then proceed to tell us that we need to let it keep happening until it is much more common. Then bring it back in again so they can see it happen. I complained to Honda USA with the same story, being that it keeps happening over and over, and they gave us the same answer..."wait until it happens so the mechanic can see it" as if it has never happened to anyone else before. This is going to end up causing people serious harm or worse. Honda is obviously trying to play down the issue to avoid cost at the expense of consumers.

When I’m stopped and try to drive my car it sometimes dies. It’s a big safety concern and happens often and when I have my kids in the car. I can’t get it to start again for a little while. The lights come on the dashboard but it won’t start at all until a while after trying.

There appear to be more than one issue. When using the auto idle feature, my car will turn off completely. Meaning the engine turns off and it is difficult to restart. I also have issues starting the car from scratch. This has occurred multiple times where the engine will not turn on but other components will. I cannot be jumped or put in neutral as the transmission won't move out of park if the engine is not on. It has been to the dealership multiple times for both issues. A software update was done to fix the auto idle issue, but it has not fixed the issue. i know longer use the auto idle feature. The most recent incident was today.

The contact owns a 2021 Honda Pilot. The contact stated that the Auto Idle feature on the vehicle intermittently failed to operate as needed. The contact stated that the vehicle failed to restart upon the depression of the accelerator pedal. The contact stated that an unknown message was displayed on the instrument panel during the failure. The contact had taken the vehicle to the dealer on several occasions and software updates were performed; however, the failure returned soon after the updates were completed. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 30,000.

When going from stop light, car died in middle of intersection. Couldn’t get it started. Had it towed to dealership.Dealer did diagnostics and couldn’t find any issue. Drove car home. Turned it off. The car would not restart. Had it towed back to dealership. Not sure if it’s starter, alternator, auto engine stop features. Battery seems to be Gett drained. Danger is that the car randomly dies and won’t start. Dealer has no idea of the issue. Tow truck driver said he has towed severs Honda pilots with the same issue.

My car, a 2021 Honda Pilot, has a feature called "Idle-Stop" where the engine stops when the break is depressed, when the break is released, the engine is supposed to start back up. Twice in the past week, while at an intersection, the Idle-Stop has engaged, stopping the engine, but failed to start the engine back up. After this occurs, I could NOT start the car back up, the engine would not turn over. The first occurrence was at the turn lane of a very busy intersection and there were numerous cars blocked by mine. Thankfully after about 30 minutes, the car managed to start up. I took it immediately to the Honda dealership where they said the car needed a software update. The dealership said the battery was fine and that there were no other issues. One week later, the same thing happened, I was a stop light and the Idle-Stop feature stopped the engine and it failed to start back. My 2 children were in the car this time, I felt very much that our safety was in danger. This time, I needed a jump start to get the engine started.
