Auto stop/start function shut down all electrical components when vehicle was stopped and the function activated. This occurred on 2 separate occasions.

During several stops now, the auto engine idle kicks in, but vehicle does not restart. The vehicle is at a complete stop with the engine off. This has happened on 2 occasions on freeway off/on ramps, which has been extremely dangerous, with the speed that vehicles are traveling. It has also happened over 4 times at intersections and stop signs. 2 separate dealerships have inspected the vehicle, where 1 was able to reproduce the issue and both times, my battery was replaced, well before the life of the battery. Maybe 1 year into having the new battery the issue presents itself again. I have owned the vehicle for just over 3 years now and I have purchased 2 batteries, that is not acceptable.

Multiple times the idle-stop feature has caused my car to stall out at an intersection. The idle-stop will engage, but when I take my foot off the break (or move the steering wheel), the car does not start again, instead it will try to start but then turns off completely. At that point I have to re-engage the break, put the car in park, turn off the car and then try to turn it back on as normal. When this happens at a green light it's very stressful and dangerous as cars are behind me. This has happened probably 10 times in my ownership period, it is always worse when it's hot outside since so many parts are running (including the AC). I have brought the car in to fix this a bunch of times, they never find anything wrong at the dealer. The last time they replaced the starter button at no charge saying that this piece was known to be faulty. It has happened once or twice since replacing that part.

At low idle, car will lock up, unable to drive, cannot put in neutral, will not go. I can't even shut the car off to restart. The dash tells be to push brake and start button, but that still does not work. I continue to push buttons until it finally kicks in. I was in the middle of the road. 1 car almost rear ended me. This also happened while I was traveling and stopped at the end of highway. I needed assistance, but since I couldn't put car in neutral, we could not push. I put hazards on and again, pushed random buttons until kicked back in. This is very dangerous! I will not let my kids take my car for fear that they will get stuck as well. I'm scared to drive it. Honda's response was bad gas or alternator, which it is NOT.

Ocassionally when stopped at intersections my 2016 Honda Pilot touring edition will go into idle stop mode and not restart. Upon trying to proceed the engine will try to start and stall out. The engine goes dead and I am unable to accelerate out of the intersection. The info dash system indicates the vehicle was in Neutral and that I needed to shift to Park to Proceed. After putting the vehicle in Park the info dash system instructs me to start the engine by pressing the Brake and pushing the Start button. This action is not possible when the vehicle has stalled out as described above and continues to prevent the driver from accelerating out of the intersection. The only solution I found that works is to remove my foot from the brake and power down the vehicle completely. Only when the vehicle is completely powered down is it possible to restart the vehicle by pressing the Brake and Pushing the power button. This event has happened 4 times in the past 3 months on my Pilot. The mileage on my Pilot is ~125,000 miles.

While at a stop the engine stopped as it should but did not restart. It then took multiple tries of pressing the brake and hitting the start button to get it to restart. This meant the car was blocking the flow of traffic creating a safety issue. This has occurred on multiple occasions with no issues found at the dealer.

- Memphis, TN, USA

The auto idle start stop does not restart automatically while in traffic or stopped. Issue has occurred several times, I must turn off vehicle completely to restart vehicle. Huge safety factor when traffic is following again and I am unable to restart vehicle.

When the auto idle stop is not disengaged (the default setting when the car starts is that the auto idle stop is engaged), the car will sometimes not restart when the idle stop occurs. It's unpredictable and scary, especially when it occurs at a light or in stop-and-go traffic. The dashboard lights up like a Christmas tree, and there is a clicking noise. I have to place it into Park, shut off the engine fully (it's not running - I think it's in Accessory mode), step on the brake and restart. Because of this, I make a habit of disengaging the auto idle stop when I start the car. Unfortunately, sometimes I forget to disengage and this engine restart failure happens. I have read that an old/weak battery is suspected. This is not true in my case. This issue has happened several times after I changed the battery on 12/15/2020. Interstate MTX48/H6 battery at $300. It's not just me - it has happened to my wife, and my 17 year old son, when driving this car. At first, I thought my wife did something wrong, then it happened to me. In total, I'd guess it's happened > 6-7 times. We try to be careful to push the button and disengage the auto idle stop. But you have to do it EVERY TIME YOU START THE CAR. If you forget or are distracted, then the problem can occur.

While stopped at a red light, with the auto start enabled, the car would not turn back on and placed the car in -??neutral-??. The dash info message prompted me to put the car in -??park-??. I did. It then instructed me to depress the brake and hit the -??start-?? button to turn the car on. It did not after I tried a few times. Finally to get it started I pushed the -??start-?? button with the key fob. It then turned on and allowed me to put it in -??drive-??.

Today was the second time my car has shut down at a traffic light in the last 2 months. The auto engine stop kicks in and the car shuts down. It took multiple combinations of pressing the start button and turning on/off the car before I could get it to restart. I-??ve recently replaced the battery so I don-??t think it-??s a weak battery.

When idling at a stop light, the auto shut off feature engaged and turned off the engine. When I engaged the gas to start moving again, the engine would not restart. I applied to brake, put the car into park and then tried to manually restart the car using the start button on the dash. The car engine would not start. The auxiliary power to the accessories would not go off when I pushed the stop/start button on the dash, but the engine would not restart either. I attempted to restart the car several times. It did not attempt to turn the engine over, but did literally nothing. I paused and waited for a minute and then attempted to restart the car again with the stop/start button and the car engine finally turned on. The exact same sequence of events has happened and two separate occasions some weeks apart. This incident put my and my passengers-?? safety at risk by stranding me at very busy intersections with no way to move the vehicle out of the road. The auto-shutoff feature has engaged while in stop and go traffic on the freeway and if this had happened then, the results could be catastrophic. I now always manually turn off this feature due to fear of this happening again and would disengage it entirely if possible, but was informed by the dealer that was not possible. No one has inspected the vehicle as the problem is not reproducible on demand, but I am willing for any necessary inspections to occur.

- Alameda, CA, USA

The contact owns a 2016 Honda Pilot. The contact stated that on multiple occasions, the START/STOP feature failed to operate as needed while at a complete stop. The contact stated that the vehicle would shut off upon releasing the brake pedal with several unknown warning lights illuminated. The contact had the vehicle towed to an independent mechanic on several occasions where several electrical components were replaced. The dealer was notified of the failure and the contact was informed that they had no knowledge of the failure. The manufacturer was not notified of the failure. The failure mileage was approximately 75,000.

Auto Idle System failure. This has been a problem for several years and continues to be a safety issue. If I don't disable the auto idle feature my car will die when I take my foot off of the brake to accelerate.. The vehicle has to do a complete computer reset before I am able to restart the engine. This has happened many, many times at stop lights when the light turns green and I attempt to accelerate, when waiting to merge onto the frontage road of I-35, when turning onto a main road out of a parking lot when traffic is backed up but someone was attempting to let me into the lane (I was half in and half out of the parking lot). In every situation, there is someone behind me expecting me to go (rightfully so). I could easily be hit if the other drivers weren't paying attention. This is a safety hazard and needs to be recalled and repaired. I've asked my mechanic about it and the Honda dealership. No one knows what to do. I've replaced the battery twice thinking maybe that would help but it didn't.

- Round Rock, TX, USA

the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the Auto Start/Stop function engaged. Making it necessary to restart manually.

- Rocklin, CA, USA

- San Diego, CA, USA

Multiple times the vehicle wouldn-??t start. The start stop switch is the culprit after 7 months of dealing with it and taking it to dealership finally. Car will cut off at stop light but won-??t turn back on. Takes like 4 tries to get it back on. Also at 126k or 128k engine had a knocking sound and needed replaced and it cost $7000 the air conditioning doesn-??t work and this is very upsetting this isn-??t why I buy Hondas. The start stop event happens everyday and every time I start the car and don-??t deactivate the start/stop system

My 2016 Honda pilot stalls when my car turns off from the auto idle engine. If I do not manually turn the feature off EVERYTIME I turn my car on my car will stall out when i lift my foot off the brake. It has progressively taken longer to turn the vehicle back on (anywhere from 30 seconds to 2 minutes) I have been to honda 2x for this issue & their "fix" has never resolved the issue. They will not admit they cannot fix it, even when I showed them a video of exactly what happens when I try to get my vehicle back on.

- Clairton, PA, USA

The engine idle-stop feature did not restart. It is available for inspection. The safety of my two small children and myself was at risk as we had to get out of the car at a busy intersection. It has not been reproduced by a dealer or a service center. The vehicle and the parts have not been inspected by authorities. It happens without warning. While at a red light, when I take my foot off the brake it shuts off completely.

- Naples, FL, USA

The Pilot has an auto start/stop function that turns off the engine when the car is stopped/idling. When the driver releases the break pedal, the engine is supposed to turn back on. The engine would very frequently fail to turn back on after idling. This happened many times at traffic lights and while stopped in traffic. It's much worse than stalling out with a manual transmission vehicle, because the engine does not turn back on quickly. The whole system (including battery power to the car) needs to be turned off and turned on again. This is a safety issue because the engine has failed to start while in traffic on the interstate, where cars are quickly accelerating, and the failure for the car to accelerate with traffic could lead to a collision. It also poses the risk of leaving the driver stuck in a dangerous location without the ability to move the car. I took the car to the dealership and they told me my battery was dying, and they charged me to replace the battery. So far, I haven't experienced anymore engine stalling with the new battery. The car has not been inspected by anyone other than the local Honda dealership. There were no warning lamps or messages prior to the failure. The failure first started in 2020, but only happened a few times. Since then, the problem increased in frequency, until I finally took it to the dealership and had the battery replaced.

- Hollis, NH, USA

I bought this car used in May 2022. My wife is the primary driver and this incident happened to her three times and myself once. When stopping at a red light, the engine turns off to save fuel with the auto start stop feature. We normally turn this off, but sometimes when we forget, the auto start fails to start the engine leaving us stuck in traffic trying to start the car at a green light. It takes multiple attempts to restart the car. This wouldn't be an issue if we could turn off the auto stop start permanently. We don't like the feature anyway, sometimes it causes the car to lurch forward when removing your foot from the break while the engine is starting.
