In support of NHTSA Action Number: PE22005 2017 Honda Pilot multiple experiences with the auto idle cutting off and not restarting. 8/4/2022 was worst experience to date. The vehicle cut off at a stop light and would not restart. The ability to roll down the windows and unlock the doors was disabled so 2 occupants were potentially trapped inside. Fortunately a door had just been opened to waive backed up traffic around the disabled vehicle. AAA and Sheriff's were called to the scene. It was successfully jumped and the AAA diagnosis was that nothing was wrong with the battery, starter, nor alternator. This is a major flaw in engineering and a fix has to be developed or the vehicle appropriately replaced.

The auto engine idle stop fails to restart the engine after stopping at stop lights, stop signs, in traffic, etc. Even after repeatedly "working" to turn off the car and turn it back on, it can take up to 2 minutes to effectively turn off the car so it may be restarted. This feels extremely dangerous at stoplights, but especially when caught in stop and go traffic on the highway or on a bridge. Cars go around into the intersection, honk, and when traffic picks up from the stop-and-go situation, cars drive by at high rates of speed while I sit motionless in the middle of the highway. While I more often than not remember to turn off this "feature" when starting the car, there are times that I forget. It has been horrible for my newly licensed driver. The anxiety and stress this has caused has led to learned anxiety while riding in and driving other cars that do not have this "feature." The problem was first reported to my local dealer in 2021. Today I asked the dealer to look at it again, while the SUV was undergoing a fix for the hood recall, and I was informed it would be a $140 diagnostic fee and then whatever the cost would be to "fix" observed problems. The dealer has not documented my complaints about said problem, though they ran diagnostics and indicated that the starter and battery were operating according to spec. They "reset" the system in November, but it did not help with the problem quickly reappearing.

While stopped at stop sign, vehicle's engine auto stop feature engaged and shutoff engine. When driver went to apply the accelerator to move past stop sign, vehicle totally shutdown. The dash instructed driver to depress brake and start engine, which was unsuccessful. Driver had to open and close door to totally shut vehicle down to get engine to turn on again.

Per PE 22-005, with Auto Idle Stop enabled, when coming to a stop light, I stopped. When the light turned green, and I let my foot off the brake, the engine would not restart, as if the battery were dead. I put the car in Park, turned it off, turned it back on, and was able to restart the engine. This happened in about March of 2021. Since that time I always disable Auto Idle Stop, as it may create an unsafe traffic condition or accident if this were to happen in traffic. I was going to replace the battery, but have not done so since the occurrence 16 mos. ago, and have had no other issues with the battery in that time.

Starting in the summer if 2020 every few weeks after coming to a stop and the auto idle stop would stop the engine. When releasing the brake the engine would not immediately restart. The pause on restart would slowly increase as the time between occurrences decreased. Occurred during each trip. Pauses increased enough that the entire control panel and radio screen would go black, and then the car restarted with warning message coming up on control panel. Contacted Honda and took it in on 9/9/2020. They couldn-??t recreate the issue. They charged the battery, did hard reset. Drove car with issue still occurring. Returned the vehicle for additional service on 9/16/2020. They are still unable to duplicate the issue and opened up a tech line case#4376911. They replaced a Dc/DC converter. Issue continued. Returned car with same issue. Don-??t know date at this time. They replaced the battery which did fix the problem, temporarily. Began having same issue April 2022. Issue slowly increasing in duration of pause and frequency of occurring. July 10 2022 started having pause long enough for control panels to go dark and get warning light when engine restarted. Started occurring daily. On Friday 7/29/22 came to a four way stop and idle stop engaged. Lifted foot off brake, pushed on gas and realized car had not restarted and car was rolling backwards. Quickly pushed on brake to to stop car rolling backwards which then car restarted with warning light. Called Honda on 7/29/22 made appointment for 8/4/22. On Sunday 7/31/22 We were driving and came to a stop and idle off engaged turning off engine at a red light. At this occurrence the dash and radio went black when foot was pulled off break. Engine did not restart. Dash lights came back on with message that car must be in park to start engine. Attempted to switch to park but controls would not until few attempts. Finally Able to put in park, start car, put in drive and pull away. Stuck in traffic lane for about 15-25 seconds. Scary.

Engine stalled at signal after auto stop and car didn-??t start back

- Mckinney, TX, USA

I was stopped at a red light. The stop idol engaged and the vehicle did not start when I attempted to make my turn. The instrument panel indicated that I should shift to park. I did so and attempted to restart the vehicle but it did not start. After a number of attempts to restart it eventually turned on and I drove straight home. I was in the middle of a major intersection with my son in the car. Car zooming by me as my car was stuck in the turning lane. If a car failing to start as a result of a feature that was integrated by the manufacturer isn-??t a safety issue then I don-??t know what a safety concern would be classified as according the this institution. Permanently shutting off the feature is not an option as it renegades every time you start the car initially. The car has stalled a few times prior to today-??s incident but this is the first time it failed to restart. As I drove home I reengaged the system to see what would happen, if failed to restart again and began the stall every time once the idol stop was engaged. This is unsafe. If I forget to turn off the function of this feature and I am on an expressway what happens if the car fails to restart, my brakes lights may not be pressed as I am thinking I am simply going to drive off and I could get rear ended at 60 miles an hour. This is a safety issue. This is a ticketing time bomb and further delays are putting thousands of lives at risk. I did I not know about the problem until I research the internet to find a solution. Why haven-??t we been informed of this problem" Is this institution waiting for the body count to be high enough to warrant a consumer alert" This is a safety issue.

Every since about 1.5 years into owning my car, the auto idle engine shutoff will stall my car. After multiple trips to the dealer who said nothing was wrong, this issue persisted until I had my battery replaced at about year 3. It started working again as it should until about another 1-1.5 years into the new battery, and it stalls all of the time especially when the car has been driven for about 15-20 minutes. I understand the NHTSA is already looking into this issue, but the manufacturer needs to disable this feature until a fix can be made. Many times, I have blocked traffic at a stop because of this and trying to get my car restarted.

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.

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.

- Wood Dale, IL, USA

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.
