On multiple occasions over the past month or so, my wife has experienced engine issues associated with what we believe is the Auto Start/Stop function on our 2018 Honda Pilot (Touring Edition). Upon coming to a complete stop, the Auto Stop function disables the engine. Upon releasing the brake, the system is supposed to restart the engine. However, on at least five occasions the engine has not restarted, and it has required her to turn the vehicle off and completely restart it as if starting from cold. This has occurred at stop lights, which obviously could cause safety issues/implications. On at least a couple of the occasions, she had to attempt to restart the vehicle multiple times by applying the brakes and pressing the main start/stop button). I frequently drive the vehicle and always turn off the Auto Start/Stop function. I have never run into these issues whatsoever. The vehicle is scheduled for routine maintenance at a Honda dealership in two days; the vehicle is serviced solely at this same dealership. The issue will be brought to their attention as well.

Our Honda Pilot began stalling four years after purchasing the vehicle. When the Honda was stopped, the engine shut off but the engine wouldn't automatically restart when the accelerator was pressed. I fortunately was able to get the Honda to restart after a couple tries.

After the car was stoped at a red light with the auto-idle feature on, the car stalled out when I pressed the gas petal to drive. The radio and A/C shut off and a PARK warning displayed. It took several attempts to turn the car back on. After the car started it took several minutes for the radio to start working again. None of the touch buttons for radio, phone or navigation would respond. This happened when I was at a light after getting off the highway. It almost caused a car accident with the drivers around me who were coming off the highway. Since this happened, every time I turn on the car, the radio stations can not be found. I have to turn the radio off/on once or twice for the car to find the stations. Frequently, when I go from stop to drive at lights or stop signs, the radio and AC will turn off for a second. This seems to only happen when the auto idle feature is on. The car transmission is also having lurching when going from 1st to 2nd gear.

While stopped at a red light and stopped at a 4-way intersection my 2018 Honda Pilot turned completely off. It was not in engine idle mode. A message flashed up on my dash saying to put my car in park.

- Indianapolis, IN, USA

Auto idle system failed and the car stalled at a streetlight. The auto-idle kicks in when car comes to a stop like it-€™s supposed to but when I release my foot off the break and the car is supposed to start back up it stalls. It can take anywhere from 45 seconds to 1 minute to get it into park and get the car to restart. During which time I-€™ve been honked at by other cars but thankfully haven-€™t been hit yet. I worry about it happening and I get hit because I-€™ve been in the way of traffic and unable to move. Very scary situation to be in. This has happened on 4 separate occasions over the last couple months, the most recent one was June 19th. I now try to remember to turn the system off every time I get into the car to drive. Dealership tested battery and it came back fine.

I was stopped at a stop light and the car was in auto engine idle. After releasing the brake when the light turned green, the engine shut off and the dash told me to put the car in park and restart by pushing the brake and hitting the engine start button. This process took about 30 seconds for the car to finally restart and I was sitting in the middle of traffic with cars behind me that had anticipated me moving forward when the light changed. Several warning symbols popped up including the collision mitigation system. This is an easy way to get rear-ended. In other instances, I have had issues where the radio and engine shuts off after releasing the brake when in auto engine idle at a stop light or driving in slower traffic but it kicks back on in just a second with no need to stop and restart. Both of these issues are very concerning. Battery life is fine, so that is not the issue. Issue stops when auto engine idle is disabled.

Car when in the idle stop has not restarted for several minutes. Some times it starts back up within 5 seconds. Other times it shuts the engine down and tells me to hit the start button to turn vehicle on, but then nothing happens. I am not even able to put car in neutral. Most recently this happened while exiting off a highway on the ramp. A bus driver pulled over in attempts to help me get the car off the ramp. However, a minute into trying to get it into neutral, the car popped back into drive and the engine on so I could get home. Car has been brought in multiple times and the dealership says they cannot find anything wrong with the car.

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.

The contact owns a 2018 Honda Pilot. The contact stated that occasionally the vehicle would hesitate while driving. Additionally, the vehicle occasionally lost motive power and stalled without warning. The contact stated that while idle at a stop light and attempting to accelerate, the vehicle independently shifted to neutral and stalled. The contact shifted into park(P) and restarted the vehicle after several attempts. The vehicle had not been diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 80,000.

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.

- Gretna, NE, 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 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"
