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.

- Bloomsburg, PA, USA

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.

- Fairfield , CA, USA

The Idle/Stop function stopped operating at a stop light. The car completely shut off. My wife pressed the brake and ignition but the car did not immediately restart. After a few long minutes, the function worked. This is the second incident with the Honda Pilot. In May 2022, the vehicle stopped at an intersection and cut off. I took it to the Honda Service and had diagnostics ran. I was charged for the test but the Service Department did not find anything wrong. They recommended a new battery which I purchased. This was in May 2022. There is definitely an issue. No use taking it back to the dealer, they don't know the source of the problem.

I own a 2017 Honda Pilot Touring addition and recently learned there is an investigation on the auto start/stop feature. We have experienced the vehicle stalling too many times to count. However, it does seem to be getting more frequent as the vehicle gets older. When the vehicle comes to a stop the feature will engage and two things may happen: 1. The vehicle will immediately die causing us to put the car in park and restart or 2. The vehicle will stall/die when in the movement of taking my foot off the brake and pressing the gas pedal. On some occasions we have had to try multiple times to restart the vehicle. The most memorable stalls happened during busy traffic and of course caused a panic as the time to restart feels like minutes when it-??s really only seconds. When this happens it has caused us fear of being rear-ended as there has been many times we braced for this as we saw an oncoming car from behind. Our local Honda dealer (Basney Honda) has attempted everything to fix but you can feel they are growing impatient with us as we demand the vehicle to be repaired.

Driving on the highway, came to a stop due to high volume of traffic, car stopped completely and auto/start turned off the engine itself like it should when brake is stepped on all the way, traffic started to move, let go of the brake to have engine turn back on like it normally would, however this time the engine did not start back on itself, tried to step on the brake and would not allow to press on it. Hit the engine start button light would come on however brake still would not allow to be stepped on, its like it is stuck. Tried this for about 5min and suddenly I was able to press on the brake and start the engine by hitting the start engine button. The component that failed is the engine, auto/start feature, power train, and electrical system. This was a big safety issue and yes it would not only put myself at risk but others safety at risk too. No the problem have not been reproduced or confirmed by a dealer No the vehicle or component has not been inspected by anyone No there was no warning when it first appear, it just happen.

- Pottstown, PA, USA

Engine doesn't starts automatically when using auto stop feature. It has happen multiple times and decided to turn off the feature completely. What happens is when using auto stop feature and if the pilot is at signal light it stops the engine. but when you lift up the break instead of vehicle to starts back up it doesn't and in fact we have to press start engine to turn on the pilot. taked to dealer about it but they say nothing is wrong with the car and never heard about it. in fact the battery seems fine to as per the dealer.

- Richmond, TX, USA

At least once a week the vehicle shuts off and don-??t restart at stop light/ sign.

- Thorp, WI, USA

I come to a full stop at a red light at a busy intersection. The auto engine idle shut off engages. When traffic begins to move I lift my foot off the brake. Usually this restarts the car. However, the engine turns off as if it is in Accessory mode. I try to put the car in Park and Turn Off and Turn On, but it requires me waiting a minute or two before I can restart the car. This problem has happened many times and I have reported it to the Curry Honda service in Yorktown Heights, NY (10598) many times. The are aware of the problem and says that there is no fix.

When the car comes to a stop at a light or intersection, the auto-idle function of the engine engages (indicated on dashboard). When you lift your foot off the break, the radio shorts out, the dashboard flashes, and the engine struggles to restart. This happens regularly. I've even had my vehicle stall in the middle of the road after auto-idle has been engaged (see video). I've taken my vehicle to the Honda dealer several times to be serviced, but each time I'm told they are unable to re-produce the problem. Last time I was at the dealer, I shared this video with them, but they communicated the same message. They can't reproduce my issue and my vehicle is safe to continue driving. I feel strongly that this is a safety issue. If I'm stalled at a busy intersection and drivers behind me are not paying attention, it is likely I'll be hit from behind. The orange engine information light in the video was for a needed oil change that I've since had completed. Video: https://photos.app.goo.gl/dnfH1v3bq31HXQWr6

Vehicle failed to restart after stopping at a stop light while auto stop feature was on (defaults on). Had to completely turn off vehicle and restart it for it engine to fire back up.

- Stockton, CA, USA

The start/stop feature on our 2017 Honda Pilot Touring has failed continuously since we owned it. The vehicle stalls when trying to re-start from the traffic signal, leaving angry drivers behind us. We now turn it off to prevent recurrence. Our local Honda dealer in Fort Walton Beach has changed a switch, but the problem continues. Their next "guess" is to change the battery, which tests good otherwise

- Niceville, FL, USA

When the engine stops when the brake is applied, there are times when the engine shuts down completely, restarting electrical systems and not starting up again. This incredibly scary and dangerous. I have brought it to the dealer who has no idea how to fix it. I read an article that this is something the NHTSA is investigating and am very relieved that there is finally some attention being paid to this problem. I wanted to log my vehicle as being effected also.

- Clarence Center, NY, USA

The idle shut off feature has shut the car off and then not restarted when it was supposed to. This has happened in two intersections and a stoplight. When it doesn-??t restart, I am unable to do anything, shift in to park or restart the car. It is extremely unsafe as it leaves you sitting in the middle of traffic or wherever it decides to leave you and you can-??t do anything with the vehicle. There is no warning when it does it. I have not approached the dealer since there is a button to override the feature I figured they would not listen. However I think it is ridiculous that you have to push a button to make sure your vehicle doesn-??t die on you while driving. I would like to see the auto idle feature removed from the vehicle.

There is a major and potentially dangerous issue with the idle stop/start feature. When the car is at a stop and the engine shuts off (gas saving feature) and sometimes the car will fail to start again, leaving me stranded in the middle of an intersection or whatever road I'm on. Sometimes all of the collision systems fail to start again (dash warning), sometimes it takes minutes to get it restarted which results in angry drivers behind me and the potential to create an accident. This issue began within a few months of buying the car. I had informed the original Honda dealership where I purchased the car but they failed to properly document the issue because there were no error codes populated by the on-board computer. After it happened dozens of times I took the vehicle to a different dealership and was able to demonstrate the problem directly to a technician after two separate appointment attempts. They then agreed to replace the battery. This helped for a time period of about 9 months and then it started again. I believe there is a wide-spread issue with the computer's ignition system and I'm not alone, although Honda seems to pretend they've never heard of the issue. I have attached my first 'documented' (although it was reported YEARS before this) service report followed by the second in which they finally replaced the battery and admitted fault. I am hopping the NHTSA can investigate and help the owners of these Pilots come to a permanent resolution. Thank you for your time.
