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.

AUTO START / STOP functionality won't re start engine after it has engaged. Engine won't crank over, multiple dash warnings come on. PUSH START bottom doesn't work, have to put vehicle back in PARK and have to attempt several times to start engine.

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.

- Reston, VA, USA

When stopped at a red light with my foot on the brake and the engine in idle, the engine turned off when I put my foot on the gas peddle. The engine idle stop was on. This occurred while stopped in city traffic (6/2022) and again when I was stopped at a red light on a highway (9/3/2022). The car rolled backward. I had to put the car in park and restart the car. I now have manually turned off the engine idle stop.

The vehicle stalls at stop signs, traffic lights and in stopped traffic. Sometimes takes multiple trys to restart the vehicle. Been happening regularly for several years. Have had multiple repairs done with no affect.

- Westborough, MA, USA

This issue has occurred twice. First occurrence was when stopped in traffic. Auto stop engaged. When brake was released auto start caused vehicle to stall-out. Vehicle restarted after multiple attempts. Second occurrence was when stopped at traffic light. Auto stop engaged. When brake was released auto start caused vehicle to stall-out. Vehicle restarted after one attempt. For both occurrences, radio was on, air-conditioning was on and outside temperature was +85 degrees. This is a serious safety concern.

The engine will stall at stoplights. It appears the auto start/stop feature fails when engaged. Car has stalled 4xs in the past week. To fix issue: You have to put the car in park, foot on brake, and hit the start engine button in order to restart the car. Also put hazards on for safety reasons. Once car starts, you can put into drive and go forward. We've been fortunate not to have an accident. It's a significant safety issue stalling at stop lights with traffic behind you. Local Honda Service center could not replicate the issue. I instructed them that you have to drive car for ~20-25 minutes before it will stall. Car was scheduled for regular A156 Maintenance. They are looking at the stall issue today, 8/26/2022.

Car has auto engine stop/restart as a fuel saving measure. Several times the car has failed to restart after turning off. This happens in highway stop/go traffic, at traffic lights. This is dangerous, as my foot comes off the brake, cars behind me think i am moving, and then the engine fails as it is restarting. I have to then put my foot back on the brake, put the car in park, and restart the engine before being able to drive again. This happened on 8/25, and 3 other times within the last month. This did also happen perhaps a year or 2 ago, the dealer did examine the car but I don't believe they found any issues to be repaired.

With increasing frequency of occurrence, the car will not start after the auto stop/start mechanism has been invoked. For example, when stopped at a red light, the engine will turn off as the car is not moving. However, once the light turns to green and the brake is depressed, the car will not start and/or will start and then the engine will cut-out. To start the engine, the car needs to be fully turned off, gear put into Park and then restarted. There appears to be something at fault with the automatic stop-start mechanism and/software. My car is a 2016 Honda Pilot Touring with less than 28K miles.

My 2016 Honda Pilot Touring stalls out at a red light while using the auto stop-start. It happens occasionally when I take my foot off the brake and put my foot on the gas. Instead of coming out of idle with the engine starting up again, the car would stall completely and I would have to put the car in park, press the brake pedal and push the start button to get it on again. I took the car into the dealer and they told me that there was no software update and that they couldn-??t do a update anyways because check engine light wasn-??t on. Also have a issue with transmission not switching gears smoothly on take off. Jerks on take of. Once again they told me transmission was fine and there was no software update and that they couldn-??t do a update anyways because check engine light wasn-??t on.

When start-stop feature is "on, " the car will not start again in certain instances when the engine is shut down after a complete stop. The NHTSA currently has an investigation opened in this matter (opened in June 2022)

- Burke, VA, USA

The contact owns a 2016 Honda Pilot. The contact stated that after stopping at a traffic light, the Auto START/STOP feature failed to operate as needed. The contact stated that several unknown warning lights were illuminated. The contact had taken the vehicle to a local dealer however, the mechanic was unable to determine the cause of the failure. The contact was informed by the dealer to replace the battery; however, the failure persisted. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 40,000.

As previously described on the NHTSA website, this model has the 9 speed transmission and it randomly turns the vehicle off at intersections/red lights when the vehicle is stopped. It is different than the engine start/stop system since the full vehicle turns off. It is very random and stressful when it happens since other vehicles are then waiting on our Pilot to get moving again.

Auto Stop/Start failure to restart issue With my 2016 Honda Pilot touring whenever I stop at red light, engine stops and it suppose to start when I release brake pedal but fails to restart when I release brake pedal which is creating a serious safety issue, I have to turn off the engine and restart it, even that may not work and it may take 1-2 minutes to restart. I have seen multiple reports regarding this same issue. Please investigate the issue. Thank you

Vehicle fails to restart after stopping at a stop light while auto stop feature was on (defaults on). Have to completely turn off the vehicle and restart it for the engine to fire back up. Happens very often. Safety concern.

- Utica, NY, USA

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. This happens intermittently, but has put my family in danger on several occasions. When the light turns green, the car turns off, and has to be put in park and restarted. I have come close to being rear-ended during these situations, as approaching vehicles have to stop suddenly because my car is disabled. I have taken a video of these incidents, but Honda is unable to recreate the issue and has not offered a solution.

- Anchorage, AK, USA

The auto start/stop feature of the vehicule has stopped working on several occassions. We would be coming off the highway and or off a red light and the car will stall of the auto start/stop function is on. This has happened a few times in a very busy intersection or street.

- Zebulon, NC, USA

Vehicle frequently fails to restart after stopping after stopping while auto idle stop feature is on (default is "on"). In thes cases, one has to completely turn off the vehicle and restart. This is a safty hazard because the engine stalls when it's supposed to come back on to e.g. cross the intersection. Honda Dealership / Service Department were not able to fix it.
