I was exiting a highway and entering a right hand turn lane. There was traffic in the turn lane and I came to a complete stop. When I stopped my car shut down. I attempted to restart by pushing the engine start/stop button but the car did not restart. It took about 30-60 off trying the butting, attempting to shift into drive and opening/closing the door and trying to restart before I could get the car to restart.

When at a stop, t he start/stop feature is enabled and the engine shuts off as expected. When I lift my foot off the brake, it doesn't always restart, and I am left stranded in an intersection or at a light, and almost in accidents. Very unsafe. I have to turn it off every time I get into the car. When I forget to turn it off, it always fails to restart.

For years, dating back to 2018, our 2016 Honda Pilot Elite auto on/off switch operations has been failing. Vehicle will not restart the engine after its engaged the auto start off. Engine and all components including electrical are off. Dashboard indications light up and essentially we are stalled, at risk of not being able to drive. It requires to place the car into park and restart the engine. This is serious safety issue that could result in being struct by another vehicle without being able to move. I have been taking the car to several authorized Honda service dealerships to address the issue. They have replaced multiple times the auto on/off switch, battery, adjusted values and updated software with no resolution. One dealership claimed to disable the auto on/off switch but this is NOT feasible. With the latest inspection, another local Honda dealership contacted Honda Corp Tech Line for assistance. Once again they instructed the dealer to perform all the potential fixes above and to ignore a code P2638. After investigating this online, Honda and NHTSA have opened an investigation June 2022 on this issue after 220+ complaints. There is no known fix, yet Honda Corp Tech Line informed local dealer to conduct value adjustments yet again, at a labor cost to us.

When the car stopped at red light, sometimes it can not restart. I got a few time too hard to restart to drive.

- Arlington, TX, USA

The engine's idle-stop feature shut off my car while stopped at a busy intersection in urban traffic, and took 15 seconds to restart the automobile. The idle-stop feature kicked in when at an intersection. When I took my foot off the brake to accelerate forward, the car instead turned off. The dashboard prompted me to shift the car into park, put my foot on the brake, and press the engine ignition button. I did so, but the car did not restart, even when I repeated the process 2-3 times. Finally, on the fourth time, the car restarted.

The Honda Pilot includes an engine-idle stop feature that is specifically for energy savings. When this feature is on, when the vehicle comes to a stop, the engine idles and then is to restart upon release of the brake and by pressing on the accelerator. On a few occasions now, upon coming to a stop, my engine idles, and then when I attempt to press on the accelerator, the engine does not restart, but rather shuts off completely. When this occurs, multiple interior dash lights ignite and it states to shift to park. When attempting to shift to park the engine still does not come on, and rather I have had to wait until I am able to fully restart the car completely. This has occurred unexpectedly while in the middle of city traffic, while at a stop lights, and while at stop signs. On each occasion, it has been a safety issue as the vehicle is idle in the middle of traffic and there is no immediate resolution.

We have a 2016 Honda Pilot Touring model equipped with the stop-start feature. This feature has failed to restart the engine while stopped at an intersection 3 times; after the first failure we try to remember to disable the feature however it must be disabled every time the car is started (worse, there is a delay in the confirmation that sometime leads to pushing the button twice and inadvertently re-enabling the auto-stop-start). The first time the stop-start failed was near the end of a long trip (New Jersey to North Carolina); it was dark out and we stopped at highway traffic signal triggering the auto-stop, there was no indication that anything was wrong. When releasing the brake, the car failed to start and went into an "off/stalled" state, leaving us stuck in the dark intersection with no lights (presumably the brake lights still worked). Given the vehicle has both an automatic transmission and ignition controlled by buttons (not a shifter/key switch); it took nearly a minute to find the right combination of button (and brake pedal) presses need to get the car restarted (as this was a highway light, the cycles are long). We took it to get the ignition system tested the next day and everything tested OK. We did not experience the issue again for roughly 7 months. The second and third time occurred in the same drive: our son sustained a compound fracture to his arm and given our proximity (less then 2.5 miles) to the ER we opted to drive ourselves there. The auto-stop-start failure occurred at a busy 4-way intersection; upon getting the vehicle restarted (in an admitedly more panicked state) we unsuccessfully attempted to disable the auto-stop-start. The failure occurred again about a mile away at the stop light before the ER; this time the car would not start back up; ultimately we let the car sit for an extremely long minute (a full cycle of the traffic light) before attempting to successfully start the car again in time for the next green light.

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.

On numerous occasions, the auto-engine stop/start feature that turns off the engine when the car comes to a stop has had issues where the engine does not restart and the car enters into an error state. I must then turn off the car, then turn it back on. Sometimes this happens after I've pulled out into an intersection but have to stop before proceeding.
