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.

- Hatboro, PA, USA

The idle stop shuts off my engine as designed but then it fails to restart approximately 10% of the time. When this occurs I have to put my car in park, turn off the car completely, turn it back on and put it in drive. While this most frequently happens at stop lights it has occured on the freeway when I have needed to stop. The frequency in which this is happening seems to be increasing. I have already had the start button on the car replaced twice. The issue continues to happen with increasing frequency.

Start stop failed in middle of intersection. The car died and would not restart without a jump. Battery has been replay and it continues

- Golden, CO, USA

Driving in traffic. Idle stop system kicked in to turn off the engine. I let my foot off the brake pedal to turn left in the intersection, and the engine failed to restart after stopping. I put the car in park, and the car would not re-start. Ultimately, I had to turn the car fully off and then back on before it would restart. I was blocking traffic for over a minute with the car unable to restart. There had been several prior instances where the car almost didn't re-start, but this is the first time that it would not restart. I have seen prior notices that the NHTSA ODI is currently investigating this issue.

The vehicle is equipped with start stop feature. The issue is it will stop, then crank for a second or two, but sometimes not restart. It-€™s a safety issue when you try to move with traffic, but the engine is now off. This issue has been reported to the Honda dealer numerous times over a 4 year period. The starter & battery has been replaced, but the issue still exists.

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.

Engine fails to restart after an automatic engine idle stop while completely stopped at a stop sign.

- Round Rock, TX, USA

The auto start/stop feature activated while I was at a stop and shut the vehicle off. When I removed my foot from the brake the vehicle stalled and would not restart. Had to place the vehicle in park and apply the brake to get it to restart. The restart took multiple pushes of the start button. This was a busy intersection where I immediately became a hazard.

- West Branch, MI, 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.

I own a 2016 Honda Pilot (Touring) model. Upon start-up the idle-stop feature is defaulted to enabled. When the vehicle comes to a stop the idle-stop feature shuts down the engine but leaves some features such as air conditioning and radio running. Upon disengaging the brake, the vehicle should automatically restart. However, on many occasions both on residential and freeway the vehicle has failed to restart and stalled. After putting the vehicle in park and attempting to restart it, it does not restart right away. Because of the stall, the vehicle appears to be left in an indeterministic state making restart more difficult and time consuming. After several tries of applying the brake and pressing the on/off button to restart the vehicle, the vehicle finally restarts. When the vehicle stalls, many of the dashboard lights come on... maybe all of them do. The major safety issue is that the vehicle becomes non-operative on busy streets or freeways. The driver will be required to turn on his hazard lights while trying to restart the vehicle. This failure places the driver and passengers at risk of being hit because it is non-operational in an environment/situation where other motorists believe you should be moving. I have made an appointment with my dealership to have it inspected. The problem has occurred multiple times on both the street and freeway. It is not always easily reproducible but has been witnessed by passengers in my vehicle. There appears to information from the public regarding this type of failure on social media.

- Rockville, MD, USA

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.

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.

My 2016 Touring Honda Pilot has an issue with the idle stop/start feature. I exited the highway and the vehicle sh*t down as I was decelerating. All of the dash lights flashed and the car would not accelerate. The flashing warning toggled bw engine idle problem and transmission. I was unable to shift gears even into neutral. After shutting the car off, It acted normally for a few weeks. Now, the car is doing it again and I had to have it towed to the dealership bc the lights continued flashing and the I couldn-€™t shift gears. Dealer says it-€™s an electronic control issue and costs $900 to repair.

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.
