When stopping for more than a few seconds auto-idle stop turns off the vehicle completely and does not turn back on by pressing the gas pedal. Car must then be completely turned off, back on and shifted into drive to continue moving.

For several year I've had a problem with the fuel-saving stop-start system on my Honda Pilot. Unless I turn this system off each time I drive it routinely (several times a week) fails to turn back on after making a complete stop, usually at a traffic light or stop sign. This has placed me in several dangerous situations as cars are speeding behind me, not expecting my car to be at a dead stop when a green light turns. It takes several tries to re-start the car and causes chaos at intersections. I took the car to a Honda dealer and was charged $975 to replace the battery, which they said would fix the problem. I have also followed all the safety recalls and yet the problem persists. I wanted to file an official report because this faulty system is a major accident waiting to happen. Given that my car fails to re-start once or twice per week, it's only a matter of time before I'm hit from behind while I'm stalled at an intersection. Honda has made it so that I am unable to permanently disable this feature and has yet to provide a repair so that it doesn't occur. Meanwhile, I've spent almost $1k trying to fix the problem myself without success. If the fuel-saving start-stop system is going to be a required feature please hold Honda accountable for providing a system that keeps their drivers safe and will not be the cause of an accident bringing harm to my family or others.

Auto stop start failed to restart the engine while in heavy traffic on an interstate. We had to put the car in park, turn on the hazards, turn the car off completely and restart it twice before engine would crank up completely. No warning lamps lit up prior to the car stalling out. We just had our emissions inspection and there were no error codes reported on the ODB scan. We took this to Honda in 2021 and they replaced the car battery but gave us no indication that the start stop feature was malfunctioning. Happy to have Honda or anyone else inspect the car.

I was at a stop light on a very busy roadway and when I let off the brake to start going, my engine wouldn-??t start and completely shut down. I was using the engine idle option. I couldn-??t do anything- my car just stalled. Some lights came on the dashboard. I tried to step on the brake to either change gears or shut the car off but it was like I pushing against a brick! The brake wouldn-??t move. Eventually I was able to shut the car off completely. After a few minutes, I was able to turn the car on but it didn-??t fully turn the engine on. After a few more minutes, I was able to turn the car like normal. I took my car to the Honda dealership near me but they couldn-??t find any problems and said they hadn-??t heard of this problem. I recommended that they Google it because I had seen a lot of complaints. I-??m now nervous to drive my car!!

The auto idle stop function caused the vehicle to stop running, needing a full shutdown and restart. This happened on busy roadways, and it has happened two times with this vehicle, one time each in different years. I think the first time was in 2021 and the second was definitely in June 2022. We have had this vehicle into a dealership multiple times attempting to resolve the issue. Each time the battery has been replaced due to low voltage, and they were able to reproduce the issue at least once. The most recent time I was informed that Honda released a service bulletin recommending a change to engine compression that may be straining the battery when restarting the engine, but I am currently waiting on Honda to decide if they will cover the cost of this service before agreeing to it. We are currently operating the vehicle with the auto idle stop disabled. Other symptoms included the electrical system blinking off and on when restarting the engine after a stop. This was reproduceable after 3-4 consecutive stops in a short period of time, such as urban driving with traffic lights. This first appeared 3-6 months after a new battery is installed.

This vehicle has the auto engine stop when sitting at a stop light. Occasionally when the engine is restarted after such a stop, it will shut down rather than restart. This is an intermittent problem, but it is dangerous when traffic is waiting for the engine to be restarted.

- Hanna City, IL, USA

Vehicle stalls in the middle of intersection while attempting to auto restart with the auto on/off feature. This has been happening since we boughe the vehicle new in 2017. Dealer said they could not simulate. Happens a few times a day.

I was at a stop sign. Auto engine shut off on car kicked in and automatically turned the engine off. When I released the brake to proceed driving, the car stalled and automatically went into accessory mode and nearly caused the person behind me to hit me. This is the 2nd time it-??s happened in the last month. I had to put car in park, keep attempting to get vehicle to start again (finally was successful) and then proceeded to drive home.

When auto idle is engaged, the car SHOULD start when the brake is released after stopping. We noticed problems when we released the brake. The radio and A/C shut down and quickly come back on again. So release brake, radio and A/C shut down and then radio and A/C come back. Reported to Jeff Wyler Honda and I believe I have a video. As of yesterday, 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. You have to put your foot on the brake, shift to park and restart. This occurred twice in two days. Once at a traffic light and once after a traffic jam on the highway. It is scary especially the first time it occurs. It has the potential of leaving the vehicle in a stopped position in dangerous locations if it can-??t be restarted, I.e. the highway. I-??ve read that a jump is sometimes required.

--AUTO ENGINE IDLE STOP SYSTEM. Yes, available for inspection upon request. --SAFETY CONCERN- Engine stalls in the middle of traffic... causing other traffic behind car to become angry and try and pass the STALLED car. As they attempt to pass, they endanger other traffic. Usually happens during heavy traffic, breakdown then needs driver to restart car completely in mid traffic and missing or heavy delay of green light which could itself potentially cause an accident. --The STALL happens constantly 1 once a month, but not able to reproduce every time car is stopped... therefore can not be repeated upon inspection. Happens at the worst time, during traffic stops. --Complaint was made during oil change, but dealer found no problem. No warning lights prior to stall. Problem has happened and reoccured for almost two years.

The contact owns a 2017 Honda Pilot. The contact stated while the vehicle was stationary at a traffic light, the vehicle stalled. The contact stated no warning light was illuminated. The vehicle was not drivable. The contact towed the vehicle to the local dealer, where it was diagnosed with needing the battery to be replaced. The vehicle was repaired. The contact stated that the battery had been replaced three times within four years. The manufacturer had been informed of the failure. The failure mileage was approximately 23,000.

The auto start/stop system on the Honda Pilot is failing at intersections causing the car to stall out and be stuck in traffic. Dealer and Honda does not have remedy for this issue. This is a known problem that is well documented by other owners. This is now happening about three times per week and I am worried that it will cause a major traffic accident and or death if I get stuck in the middle of an intersection.

When breaking at a stop. Entire car shuts off instead of just the engine. Turns off and have to restart car while in traffic. Has occurred 4-5 times so far.

It took my Pilot into the Honda dealership because the car repeatedly stalled at when the auto engine idle is engaged and I let off the brake, putting mine and my families in serious danger. Honda originally said they couldn't duplicate the issue or figure out why it was happening and sent me on my way. When it happened again, I took it back to Honda and was told it was the battery. I was hopeful that this was going to solve the problem, but it has not. It continues to stall intermittently if I forget to manually turn off the feature after starting the car. After searching the internet, I found that this is a common problem and that Honda is not doing anything to permanently solve the issue. Please investigate this before someone is killed!

Issue: engine sometimes does not start after engine idle stop activates On several occasions while stopped at traffic lights the engine failed to start requiring the driver to turn the vehicle off then back on. This occurs after the engine idle stop actives. When the engine stops electrical components, such as the radio, momentarily lose power. The dealership was not able to reproduce the issue. Members of my household have encountered this issue several times a week over a 2 month period. This is a safety issue as the car does not reliably start in traffic.

The auto start and stop engine feature leaves the car stalled and unable to restart until multiple attempts. We have been stuck in the middle of a highway multiple times with hazards on trying to restart

- Springfield, VA, USA

When exiting the interstate and stopped at stop sign, vehicle shut off due to auto stop/start feature. When I released the break to go, the vehicle did not start and completely shut down. The vehicle had to be placed in park, break pressed and ignition button pressed again. It took a little bit but it did start again. After this incident, this has also happened about 10 more times stop lights around town. It has always started again but it takes a minute to restart and multiple steps are needed for it to be restarted. Traffic has been backed up while I attempt to restart the vehicle.

- West Fargo, ND, USA

The engine with shuts off normally when I come to a stop when I have the system engaged. The problems begin when I take my foot off the break expecting the engine to start up again. What happens consistently (though not all the time) is that when I take my foot off the brake, the engine shuts off, shifts itself into Park, and I have trouble getting the engine to start up again. When I disengage the system, which I do practically every time I drive the car now, everything works fine. The dealer din't find anything when they ran a diagnostic, so I'm at a loss.
