I was at the red light stop, when I got green light, I moved my feet off of brake, engine did not wake up or restart. I pushed gas pedal but the car would not move, then it showed all kinds of lights on dashboard. Afterwards, the car showed a sign asking to shift into parking, which I did. The engine start button could not restart or turn the car comepletely for a minute. After 2 minutes the card started it again and there was no light on dashboard.

The following has occurred 3 separate times. The first time occurred in July 2021. When stopped at traffic lights, the engine shuts off to conserve energy but then has difficulty restarting. When the light turns green, we take our foot off the brake and the engine does not restart. Instead, the ignition button light flashes and the car is unable to shift into gear and appears to be in neutral. The only way to solve it is to shut the car off and restart it. This process takes anywhere from 20-60 seconds. This has caused us to stall at lights and cars behind us have to go around, which creates a safety concern. After the first instance, we brought it to our Honda dealership and informed them. They inspected the vehicle and were unable to find anything wrong. They also were not able to reproduce it. There were no warning lamps or messages prior to or after the incidents.

Several times I have been driving with the auto stop on. When I get to a stop light or traffic light to make the stop, the engine shuts off as it should. When I let off of the brake and go to accelerate, the engine appears to start, then shuts all of the way off. This creates a problem where the lights on the dash flash and errors start flashing at me because I did not shut off the vehicle while in "Park". I have to push the P button and pump the brakes to get the engine to turn back on. It is a process which feels like it takes forever when other motorists are honking and yelling at me in my disabled vehicle. It probably takes 45-90 seconds, but feels like an eternity. This has unfortunately happened at one of the busiest lights in our city. I almost got rear ended with my 3 kids in the car as I sat trying to get the vehicle to turn back on. This has happened about 4 or 5 times. Now I shut off the Auto Stop every time I get in the vehicle. My kids don't want to ride in the vehicle anymore since they think it is unsafe. I took it to the Honda dealership and they replaced the battery despite telling me it was okay. I have not gone back to turning the Auto Stop on because I feel this is a huge safety issue.

The automatic stop start on the engine fails to restart at lights and when stopping in heavy traffic. One time it happened luckily I was in a parking lot I had to get out of the car out of key fob range and it seemed to reset. Before I got out everything on the dash was frozen nothing would turn on or off. I-??ve been pressing the button when I get in the car that overrides it but sometimes I forget. When it-??s active and does restart at a red light it lurches ahead so much that you almost hit the car in front. It-??s a horrible feature. This is ongoing problem.

- Arnaudville, LA, USA

Engine failed to restart after the auto stop/start feature shut the engine off while I was stopped making a left turn onto a busy road. This is the 3rd time this has happened. I am unable to disable this feature permanently. I have to shut this feature off manually each time I start the car. The prior two times I was stopped on a busy road for a car stopped in front of me and the car failed to restart exposing my family and i to a potential rear end collision. This feature is very dangerous and it is only a matter of time till someone is hurt.

When stopped in traffic the car will switch to neutral by itself. It will turn off and will have to be restarted. This has happened about 12 times since last July. After the first time it happened I brought the car to the dealership. They were not able to replicate the issue and it has continued since then with greater frequency. (2x last week in 3 days) This has happened when in econ mode, regular mode, right after a tune up, no pattern detected. Sometimes before it happens there would be a spluttering sound of the engine, sometimes a clicking sound, sometimes a collision warning sign flashes right before it happens, sometimes no warning- the car just shuts off and needs to be restarted. When the car is idling there are frequent reminders about pressing the break to shut off the engine. Googling this issue shows other people have the same problem with their 2018 Honda Pilots and other models as well. I believe these incidents are related to ODI Investigation PE 22-005 just opened on 06/03/22.

The engine automatic idle stop malfunctions on a regular basis. At idle, the engine will stop and is supposed to re-start automatically and on average once per week the engine will not re-start. The car will need to be put into park and then manually restarted. This usually occurs while at a traffic signal and leaves us stuck blocking traffic. It has occurred countless times in the three years we have owned the vehicle. We have taken it back to Honda multiple times to complain but they have never been able to find a problem.

- Lexington, KY, USA

Car shuts off and does not turn back on properly when stopping while driving. It does not happen all of the time, but when stopping at light/stop sign the car will turn off like it is supposed to but fails to start back up. When it fails to start it will not start back up, because the car is not in park, so the push button will not work until you hit the park button.

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

- Bel Air, MD, USA

I just read about the auto stop / start difficulties applicable to my vehicle and reportedly corroborated by Honda. I may have twice experienced the same or similar failure. Fortunately, both of my experiences were in my driveway. Safety was a concern in that I could not start the car, and it was blocking my other vehicles. I am unsure of the date, but I think that both were last summer. My recollection is somewhat vague as these were a while ago, and I was able to rectify. In both cases, I pulled into the driveway. I am guessing that the auto stop turned off the engine when I came to a stop. I most likely only pressed the engine start/stop button and put on the emergency brake after coming to a stop. I usually do not press the park button as it unnecessarily restarts the engine. In both cases, tried to restart the car a few minutes later, but it would not start. I don-??t know whether or not the car locked. I use the automatic lock feature but may have had a door or the tailgate opened. I don-??t know whether or not I used my key fob at all in trying to restart, or whether or not I moved the key fob near the start button. I remember the car seeming like the battery was dead. In one of the cases, I definitely used jumper cables from another car. In the other, I may have used a charger. The article did say that a jump was required to restart in some cases. At some point, the car just came alive. In the case of the jumper cables from another car, I moved the car out of the way (rolled up several yards) and shut it off and then restarted. The car restarted strongly, and the car acted like nothing ever happened. It almost seemed like a security lockout had occurred. Until there is a fix, I would like to know is what sequence is needed to restart if I have this problem again" Can you please help me with this"

- Bear, DE, USA

My car shuts off all the time. I called Honda last year to let them know because I was concerned there had been a recall. I took it to the dealership. They did some transmission work. One time it shut off when I was going 60mph on the Highway. It will also shut off when I-??m actively breaking and not to a complete stop yet. I-??m very concerned for my safety. Again, I reported this to Honda customer service and they told me there was nothing they could do. This has been going on for over two years.

The engine failed to restart on its own from a complete stop at a traffic light on three separate occasions with the Auto Start/Stop function engaged.

- Scarsdale, NY, USA

My vehicle was stopped at a red light in a busy turning lane. When I pressed on the brakes to stop the vehicle the "idle-stop" automatically came on. As my vehicle was idling, I waited for the light to turn green to go. Once I pressed on the gas to go my vehicle went haywire. I couldn't drive forward or put the vehicle in any park mode. Every light started flickering on the dash, MY HAZARDS WOULDN'T COME ON, the car wouldn't start and every time I tried attempting to turn on the car it continued to do the same. I was stalled at a very busy intersection with no hazard lights with two kids, this was frightening. My husband had to restart the vehicle with a battery pack. After getting the car checked, there were no signs of any battery issues or any other problems, the car seemed perfectly fine. Now we have to completely turn off the "idle-stop" before driving or the car will stall, shut off and go haywire. We have to constantly restart the vehicle with a battery pack in order to continue driving. I asked several people and apparently this is a huge issue and problem for many with no help from Honda dealerships to fix it.

- Cottonwood, AZ, USA

Engine misfires randomly causing car to go into limp mode. Car was unable to go pass 40 mph on while trying to merge highway. It was very dangerous and scary as cars came very close to my bumper. Honda is aware of an injector issue and has extended the warranty, but this should be a safety recall.

- Brooklyn, NY, USA

The auto engine idle "feature" automatically shuts the engine off when the car comes to a stop. This "feature" is supposed to improve gas mileage, however, I believe it is very dangerous. This "feature" has caused my vehicle to stall numerous times in stop and go traffic, requiring me to completely stop the vehicle, place it in park, and then restart the vehicle. This sequence has created several scary and dangerous situations where I was completely stopped on a busy freeway. This "feature' WILL cause accidents if it has not already caused them. This feature currently cannot be permanently disabled. It must be disabled manually every time I drive the car. I have also contacted Honda directly to notify them of this defect.

- El Segundo, CA, USA

The Auto-Idle feature will unexpectedly over-engage while coming to a stop and the entire vehicle will shut off. I am unable to shift, steer, etc. It will also completely shut the engine down when at a complete stop. To be clear, this is not the normal auto-idle. When the full engine disengage happens, the entire vehicle loses power and the dash flashes. The vehicle states, "put into P". Once in "P" for park, the vehicle still will not restart. It is as if the vehicle has to "reset" itself. It has taken upwards of 4 minutes for the vehicle to restart. This has happened on a highway during construction traffic, approaching a stop sign, slowing at a red light on multiple occasions. I have almost been rear-ended as a result on mutiple occasions. I am not even able to put the vehicle in Neutral to move it to a safe spot. Honda informed me that I "just need to disengage this feature each and every time I start the vehicle". That is not the solution. This feature should be permanently disabled by Honda. Immediately.

I was driving my kids to school when I stopped at the school intersection. I go to press on the accelerator as I normally would and it would not drive, so I pressed on it a little harder as I was turning left since there were cars approaching. My vehicle suddenly jolted, making myself and the kids shift/jump from the force. I then proceeded driving down the road and let go of the accelerator, and my SUV suddenly started to feel like it was slowing itself down instantaneously. It felt like it was trying to make the vehicle's speed go down to 0. I then pressed on the accelerator again to prevent it from happening, but it continued to do so whenever I let go. I had to stop at the school's parking lot and turn off the SUV completely. When I turned it on again and began to drive, it was functioning normally. Since then, it has happened about 3 or 4 times, 1 of which happened on the expressway, which was way scarier. I had to get out of the expressway as it was dangerous. Just yesterday, I had a separate issue with the SUV that may seem related in retrospect. My SUV did not want to turn on. I experienced all of the dashboard lights flickering, and being unable to start it. It was not the battery because at some times, the radio would turn on, the lights, and the windows/locks would function normally. I was unable to get the vehicle to go to neutral, or anything then on. When the lights were not flickering, it presented me with the smart entry system light problem. Soon after, all the lights on my dashboard turned on and stated there were air bag problem, brake problem, abs problem, and etc... My vehicle is currently being looked at.
