When auto stop/start engages the vehicle occasionally will experience a complete engine and electrical shut down when auto start is supposed to engage; the is often leads to a dead vehicle in traffic at an intersection. Occasionally it will have extreme difficulty with a restart, often only starting after several attempts at push button starting. Fuel injectors and battery have all been replaced recently, fuel injectors under recall/manufacturer issue and battery at replacement lifetime. Is often unpredictable when it will cause issues and when it will operate correctly. Has occurred intermittently for several years with a somewhat unpredictable pattern.

When stopped at a red light with my foot on the brake and the engine in idle, the engine turned off when I put my foot on the gas peddle. The engine idle stop was on. This occurred while stopped in city traffic (6/2022) and again when I was stopped at a red light on a highway (9/3/2022). The car rolled backward. I had to put the car in park and restart the car. I now have manually turned off the engine idle stop.

My 2016 Touring Honda Pilot has an issue with the idle stop/start feature. I exited the highway and the vehicle sh*t down as I was decelerating. All of the dash lights flashed and the car would not accelerate. The flashing warning toggled bw engine idle problem and transmission. I was unable to shift gears even into neutral. After shutting the car off, It acted normally for a few weeks. Now, the car is doing it again and I had to have it towed to the dealership bc the lights continued flashing and the I couldn-??t shift gears. Dealer says it-??s an electronic control issue and costs $900 to repair.

This issue has occurred twice. First occurrence was when stopped in traffic. Auto stop engaged. When brake was released auto start caused vehicle to stall-out. Vehicle restarted after multiple attempts. Second occurrence was when stopped at traffic light. Auto stop engaged. When brake was released auto start caused vehicle to stall-out. Vehicle restarted after one attempt. For both occurrences, radio was on, air-conditioning was on and outside temperature was +85 degrees. This is a serious safety concern.

Car has auto engine stop/restart as a fuel saving measure. Several times the car has failed to restart after turning off. This happens in highway stop/go traffic, at traffic lights. This is dangerous, as my foot comes off the brake, cars behind me think i am moving, and then the engine fails as it is restarting. I have to then put my foot back on the brake, put the car in park, and restart the engine before being able to drive again. This happened on 8/25, and 3 other times within the last month. This did also happen perhaps a year or 2 ago, the dealer did examine the car but I don't believe they found any issues to be repaired.

With increasing frequency of occurrence, the car will not start after the auto stop/start mechanism has been invoked. For example, when stopped at a red light, the engine will turn off as the car is not moving. However, once the light turns to green and the brake is depressed, the car will not start and/or will start and then the engine will cut-out. To start the engine, the car needs to be fully turned off, gear put into Park and then restarted. There appears to be something at fault with the automatic stop-start mechanism and/software. My car is a 2016 Honda Pilot Touring with less than 28K miles.

- Brooklyn, NY, USA

My 2016 Honda Pilot Touring stalls out at a red light while using the auto stop-start. It happens occasionally when I take my foot off the brake and put my foot on the gas. Instead of coming out of idle with the engine starting up again, the car would stall completely and I would have to put the car in park, press the brake pedal and push the start button to get it on again. I took the car into the dealer and they told me that there was no software update and that they couldn-??t do a update anyways because check engine light wasn-??t on. Also have a issue with transmission not switching gears smoothly on take off. Jerks on take of. Once again they told me transmission was fine and there was no software update and that they couldn-??t do a update anyways because check engine light wasn-??t on.

When start-stop feature is "on, " the car will not start again in certain instances when the engine is shut down after a complete stop. The NHTSA currently has an investigation opened in this matter (opened in June 2022)

- Burke, VA, USA

As previously described on the NHTSA website, this model has the 9 speed transmission and it randomly turns the vehicle off at intersections/red lights when the vehicle is stopped. It is different than the engine start/stop system since the full vehicle turns off. It is very random and stressful when it happens since other vehicles are then waiting on our Pilot to get moving again.

The auto engine idle feature malfunctions. When stopped in traffic and at intersections the auto engine idle feature turns off the engine; however fails to restart. I can put the car into park, but the brake remains engaged and the ignition button blinks white. I have attempted many different things to 'reset' the computer. Putting the car in park, waiting, unlocking seatbelt, open/shut door. The last time, i had to walk away from the vehicle with the key fob in traffic. Locking and unlocking the car seemed to reset the computer. This placed me in dangerous traffic. It has happened in a construction zone on interstate, at intersections several times, during rush hour when it was impossible to leave the vehicle due to high speed traffic, and once while towing. Each episode has generally taken about 15 minutes for computer to shut down/reset. There is no message on the dash before, during or after. I now disengage the auto engine idle button when driving due to fear of being stranded in dangerous traffic situations. If I forget to turn it off, it is likely to malfunction. I have contacted the dealership about this problem before. There was no code, so the problem was deemed a mystery and remains unresoved by Honda.

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. This happens intermittently, but has put my family in danger on several occasions. When the light turns green, the car turns off, and has to be put in park and restarted. I have come close to being rear-ended during these situations, as approaching vehicles have to stop suddenly because my car is disabled. I have taken a video of these incidents, but Honda is unable to recreate the issue and has not offered a solution.

2016 Honda Pilot stalls during idol-start stop. Driver is forced to put it into park and restart vehicle. I took the vehicle to Manchester Honda (CT) for service over a year ago, but no issues were found. They updated the software, but it did not help. The issue is getting worse - sometimes it takes multiple attempts to restart the vehicle. This is a serious safety concern as it has happened in the middle of a busy intersection and in the middle of the highway in traffic. It is currently not possible to disable the system and I don't always remember to manually shut it off every time I start the car.

When the car is locked, the alarm will randomly keep going off and the cluster randomly flickers.

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.

- Madison, OH, USA

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.
