When stopped, the engine idles off but when I go to accelerate, the engine shuts off. This is becoming a safety issue as the last two times were on a highway although it is really always a safety issue. Last year the dealer had me get a new battery. While that worked for a bit, the issue is back and worse than ever.

The auto stop/start feature is defective. It turns off the engine when stopped at red lights, but many times the engine then fails to start again when the gas pedal is pressed when the light is green, and the car stalls. This has left us stalled in intersections many times, and sometime it takes 10-15 minutes before the car starts again. We even had to call for a tow once. This problem has been ongoing for a few years and I have communicated it to my Honda dealership many times, and have brought it in multiple times, and they have failed to rectify the issue.

I stopped at a red light and the idle stop function shut down like it should. When the light turned green, I let my foot off the brake and it stalled out. Some of the dummy lights came on and it stated that I needed "To start engine: brake + push" and shows the break pedal and the Start engine button on the dashboard. So I did. It did nothing. I had to turn the car off and try to restart it. I had to do this 3 times for it to finally start back up so I could drive off. This has happened to me a total of 6 times now. All but one time was at a red light, once being at a roundabout as I was slowing down for a car coming toward me. Today I had to restart it 4 times, open my car door, take my seatbelt off and close my door back before it finally started back up. I have taken it to the dealer once before and they told me it was because my battery was weak and would not make the connection when it went to start back up. They said they 'fixed' it to the best of their ability and just basically hoped it would not happen again. Well, it did. I just had my battery checked last week and it is fine. I have a physical video of it as it is happening. As soon as my car shut itself down "stalled out" I grabbed my phone and videoed it. I am keeping the video on my phone. This is NOT safe. If I can't move at all, it will not go into neutral or anything, so I would not be able to physically move the car into the emergency lane out of traffic or anything.

While a stop light, the Idle Stop feature engaged as normal, however when the brake was released the engine failed to restart. This is not the first time this has happened, but this time following the instructions on display, place vehicle in park and press the Start/Stop button, didn't work. It was at night and I figured I would turn off the lights and radio to help. It took 4 or 5 attempts to get the vehicle to restart. This happens more frequently when idle stop is engaged short order, such as in a long line waiting for a left turn.

Vehicle idle or auto start /stop is not functioning.. It has happened multiple times incluiding today 09/23/2022, were the vehicle shuts of and it doesnt start.. All this codes and instructions come up to try to turn the vehicle back on... It always happens is a street light and most of the time is a busy intersection with cars honking and the vehicle is off... IT IS VERY UNSAFE... It takes a couple of minutes to start the car on.. My wife has been stranded for 10 minutes in the middle of traffic going by trying to start the car.. I had this issue at 40k miles and took it to the dealership and paid $746.96 to get the Valve adjusted to correct auto start... Now at 73k miles is happening again... It started at 60k.. Today 09/23/2022 im at the dealership and they say the cant find any code THIS IS A SAFETY ISSUE...

The contact owns a 2017 Honda Pilot. The contact stated that while stopped at a stop sign or light with the brake pedal depressed, the engine turned off; however, when the brake pedal was released the engine failed to restart as designed. The contact stated that the START/STOP button had to be depressed to start the vehicle. The contact stated that no warning lights were illuminated. The vehicle was taken to the dealer for diagnostic test however, the dealer was not able to determine the cause of the failure. The contact stated that the dealer replaced an unknown gasket, checked the battery, and performed a warranty valve adjustment but the failure continued. The vehicle had been to the dealer at least twice for the failure. The contact stated that upon picking up the vehicle from the dealer, the failure reoccurred. The manufacturer was made aware of the failure and a case was opened. The approximate failure mileage was 30,000.

- Champaign, IL, USA

5 times now we have been stopped in traffic and the auto stop/start function correctly stopped the engine but the car would not start back despite multiple attempts. Thankfully after about 30-40 seconds the dash lights come back on then the start button will respond and the car will crank and run normally

- Calhoun, LA, USA

Multiple times in the past year the car has stalled when at a complete stop. It's when the car idles down and then we try to go by stepping on the gas. The engine dies completely and we need to put the car in park and then restart the car. This is very dangerous when in traffic on the highway or starting on a green light or stop sign with cars behind us. We've talked to the dealer numerous times and they haven't had any solutions. We need this fixed but think Honda should be paying for it, not us.

On multiple occasions now my Pilot has completely shut down while the auto-idle is on and I have been unable to restart it quickly. My young children and I have been stuck in traffic multiple times unable to move or get out of the way of oncoming traffic due to this and most recently on 9/16/22 I was almost hit due to be unable to restart my vehicle. I typically keep the auto-idle off for this reason but if I forget to turn it off, it happens again. I purchased my car on 7/06/22 and this has happened 3 times (which is a very high percentage of the time the auto-idle is accidently left on). I have tried to take it into be serviced but it does not happen every time so they have been unable to assist. There are no lights on, messages or any indication when this happens, the engine just shuts completely down and takes a minute to allow you to put it into park and restart the engine by pressing the break and the start button. This is terrifying for me, my children and everyone else on the road that has almost hit my idle car. I am scared every time I get into this car and unsure what to do at this point.

On many occasions, when the vehicle is stopped (at a light or in gridlock), when I remove my foot from the brake to apply the gas, the engine stops and the vehicle shuts down all systems (audio, nav, etc). When this happens, for a very brief time (too short to get a photo) warning lights related to the collision and/or emergency braking systems flash. After those lights go away, the dashboard lights indicate that the vehicle is in neutral (not by my doing) and that I must press the brake, put the vehicle in park, and restart the vehicle. This process does not always work the first time and the delay of turning off and restarting the car, even when it does work, causes a dangerous situation in traffic. When this happens on a downward hill, my vehicle rolls forward as it -??dies-?? and I am sometimes stuck in the middle of an intersection as I try to restart the vehicle as quickly as I can. When it happens in heavy stop and go freeway traffic, I-??m often surrounded by vehicles traveling at high speeds. I-??m terrified that my baby and toddler will be hurt in this vehicle. I find it egregious that Honda has not issued a fix, a recall, or any other option for owners of vehicles with such a dangerous flaw.

The car sometimes fails to restart on its own from a complete stop at a traffic light or stop sign with the Auto Start/Stop function engaged. Furthermore, on two recent occasions the car would not start at all after it was turned off to get gas. One of those times it sat for 40 minutes at the gas pump while waiting for a jump start (it eventually started on its own), and the other it had to be towed to the dealer. After the first incident, we were told there was nothing wrong with the battery and a month later, when the car had to be towed, we were told the battery was completely dead. The concern with the start/stop trouble has been reported to the dealer and we were told there was nothing they could see. There have been no warning lights, lamps or messages. The start/stop problem began approximately a year ago, and we have tried to turn that feature off when driving, due to the problems that occur, since we were told there wasn't a problem that could be seen. On the occasions we forget to take this step, it always struggles at a stoplight or intersection and if not caught in time, the car will stall out, sometimes taking 2-3 tries to restart. The vehicle is currently in the shop, awaiting a battery replacement as we have been told that is what is causing the start/stop issue.

When stopped the engine shuts off. It does not always turn back on when attempting to accelerate.

Vehicle failed to restart when stopped at signal light the idle function shut the vehicle down but I had to completely restart the engine rather than it automatically restart as usual. A real traffic hazard

Engine fails to restart on its own from a complete stop at a traffic light or intersection with the Auto-Idle Stop engaged.

- Panama City, FL, USA

Since purchasing my car in 2018 the idle stop sometimes seemed like it "glitched". It would take an extra second or two to restart, the radio would turn on and off and lights on the dash would flash, but the car still worked. Within the last few months I've had 3 occasions where the car just wouldn't start again when I hit the gas. I need to shut the entire car off, wait a few seconds, and restart the entire car. This is extremely scary when you are stopping for a quick turn and an huge safety concern when your car won't go when you hit the gas during an unexpected stop (during a turn, at a red light, stop sign, etc.)

On multiple occasions, the engine idle stop system has failed to restart the engine at an intersection when releasing the brake leaving the car disabled in a dangerous situation. This started after about 20k miles. When it happens the car is fine until brake release. It seems to try to restart but the entire car loses power. No lights, no anything. Won't restart at first either. After a few moments trying to get it to restart it will fire up and you can put it back in drive and continue. I did note it happened less when I replaced the battery for a while. Dealer has replaced fuel rail and ignition switch to no avail. As a car guy I can say when it happens it's almost like there is not enough power to throw the starter. At that moment it's like all the power is sapped away like a bad ground or something. But then it comes back because obviously it restarts after a bit. Battery, Alternator and starter tests are always good. We now turn engine stop off every time we start the car out of fear but there is no permanent off switch.

My 2017 Honda Pilot has intermittent issues with the automatic idle feature at stops. It will sometimes stall out completely, requiring me to shift to park and restart the car completely. This feature has never worked properly; therefore, I have to shut the feature off everytime I drive for safety. I have told my dealer about this problem numerous times and they have -??not been able to replicate-?? the problem. They have replaced battery for this reason at least once but it did not fix the problem.

- Jacksonville, FL, USA

When my car had the engine disable feature on the car will stall out usually at traffic lights or even in the middle of intersections. When it stalls it will not start sometime for a few minutes. I have been stranded in the middle of intersections multiple times and cars have come close to hitting

- Fairfield Township, OH, USA

I have experienced several instances where the vehicle's auto stop-start system fails to restart the vehicle's engine after a stop. This has happened 2-5 times. Specifically, when the vehicle is at a full stop (with brake fully depressed), the auto stop-start system is designed to stop the engine to conserve fuel by turning the engine off. During the episodes at issue, the system works correctly to stop the system. However, when I have released the brake pedal and attempted to resume driving, the engine has failed to restart and the power system appears to fail/reset. The vehicle then requires that I attempt to restart it using the stop/start button. On at least one occasion, I had to make multiple attempts to restart the vehicle before it finally began operating again. This situation often results in the vehicle obstructing traffic for an extended period of time and creating a dangerous situation. I have begun disabling the auto stop-start system when driving the car to avoid this problem occurring.
