July of 2019: Wife complains the vehicle starts back up under protest from the start stop system when driving in stop and go traffic (more so on hot days) on city streets. Eventually, vehicle intermittently stalls when she tries to resume travel from start stop mode. Vehicle eventually restarts after 120 seconds or more. Problem occurs on multiple occasions. Vehicle taken to dealer, dealer claims they cannot replicate the problem. However, testing shows a bad cell in the battery (just out of warranty). Battery replaced. Problem seems to be sorted temporarily (although my wife routinely disables the start stop function to avoid the potential problem). May of 2020: Same problem as before, car stalls when trying to resume travel after start stop mode. Vehicle won't restart for a few minutes and cannot be pushed out of harms way. It stands to reason that the issue is probably not the battery, the battery is oem and less than a year old. The most worrisome aspect of the situation is this. When the vehicle stalls (I.e., the engine is not running) the vehicle cannot be placed in neutral (without going under the hood and using a special tool) and pushed to safety. Hence, the vehicle is absolutely stranded until it restarts. This is a dangerous situation when stalled in rush hour traffic.

The auto engine idle (aei) feature has a flaw in it that Honda has apparently not identified or explained and it is a serious safety concern. Aei shuts the engine off when the car is in drive but fully stopped and, in theory, increases fuel efficiency by reducing engine idling when the car is stopped, e.g. at a stoplight or in stop-and-go traffic. While there is a button to disable it, this button has to be pressed each time you turn the car on and cannot be permanently disabled. We try to remember to always press the button and disable the feature but occasionally forget and don't realize we haven't disabled it until we come to a stop somewhere and the feature engages and the engine shuts off. Aei would just be a nuisance if it worked 100% of the time as it is designed to work but, unfortunately, it doesn't. when it works and the brake pedal is fully depressed, the engine is automatically idled, and then as you begin to lift your foot off the brake pedal, the engine quickly turns back on, you're already in drive, and you go. However, on what seems to be a completely random and unpredictable basis, sometimes when you begin to lift your foot off the brake pedal, rather than having the engine restart automatically, the entire car just goes dead. At this point, you have to frantically put the car in park and completely restart the engine. If you're lucky, this happens quickly and you're not stuck in a compromised spot with no one bearing down on you from behind but by its design you are somewhere you need and want to be moving from quickly, and it has happened at the exact moment when you try to accelerate. This has happened to both myself and my wife a handful of times in scary situations. Read all the other complaints on the internet - no service rep anywhere has an explanation. This needs to get solved before people die, if they haven't already. See updated version, too many characters.

This is in regards to the idle stop "feature" of the Honda Pilot. When the vehicle comes to a full stop, the engine cuts off in order to save fuel like it's supposed to. However, when it is time to move again, the vehicle randomly stalls causing the car to completely turn off. This can be potentially fatal as the brakes then do not engage fully (car is off) and a message appears in console saying "to start engine: Press brake and push (engine on)". this is most definitely a safety issue especially if this happens in the middle of traffic. Honda says it is not covered under any warranty. This behavior is random and unpredictable.

Car shuts down completely T a stop position and computer readout instructions are to put the car in park and then go thru initial start actions. Purchased car in Feb 2019, problem started within days of purchase. Returned it to dealer multiple times with no improvement, Feb 26th 2020 took car to dealer again due to this problem and the radio effected the last shut down time with a loud buzzing noise. Was informed they would have to keep car overnight so the valve clearance could be checked while car was cool. I have found that this problem has been ongoing for four years. It is unsafe and very nerve racking when your car dies through no failure of the driver and other impatient motorist sounding their horn because you aren't moving. One has to worry about one of those impatient drivers not paying attention to what's going on and hitting their gas pedal when the traffic light goes green and all of a sudden you are rear ended. Four years is long enough, even I realize that this problem didn't start with these cars until the introduction of the electronic computer shifting and the auto stop shut down process was introduced in these cars. This shut down of the engine has only happens on public streets and when the vehicle is stationary. Honda of gainesville, fl has an open case on my vehicle. Records are on hand if needed.

The auto engine idle stop system problem warning message presented. Dealership cannot find anything wrong- but light appears in dashboard when car is turned off and will not alarm.

- Maumelle, AR, USA

While driving, I received an alert that "some driver assist systems cannot operate." Lights indicated that the collision mitigation, and lane departure, and lights were affected. I do not want the collision mitigation system to randomly disable (or any system for that matter). The dealer performed a hard reset on my system and we'll see if it's fixed. Still, it posed a hazard to me at the time.

About 6 months ago, when my car had less than 30K miles. My car would stall while the car was in "auto idle-stop mode". initially, I first noticed that the auto idle-stop was hesitating when it would start up. Then things got worse and I noticed that the radio would turn off and I'd hear all of the chimes like when I start the car. I brought my car to Honda to have this fixed. They said it was the computer and claimed they fixed it. The problem still continues. I also had a conversation with the service manager and he promised he would inform Honda corporate. I never received any follow up. I googled this problem and have found out I'm not the only one. This is dangerous because sometimes I need to make a turn and my car has stalled and adds a few seconds. There are other people experienceing the same problem: Https://www.piloteers.org/threads/elite-shuts-off-at-stop-light.157005/

Upon exiting stop/start events(auto shut off at stop signs/lights/parking lots), engine does not restart. Instead, it shifts into park, lights up all instruments on display panel, and requires a manual restart. Vehicle is dead until restarted, posing a hazard to occupants/oncoming traffic. Has happened multiple times in past weeks. We also have read of many other owners of '16/'17 Honda Pilot owners having the exact same issue.

- S Huntington, NY, USA

Twice the exhaust light and all panel lights has come up. The fist time the car was a few months old and the car was not even on, it happen when car was started. They fix the first time the second time they charge us even the car is not 50000 miles old.

Huge/loud pop of radio, car doesn't beep, is still in drive, but is dead when: Stopped but not sure that autostart is on' both times this horrible one happened, it was a very brief press on the breaks (11/5: on freeway; 11/6: at stop sign). Screens on dash popped loudly, and suddenly engine was dead. C.situation: This was not a full autostop issue, so there wasn't any expectation that it was going to restart, rather it was still in drive and the engine was going. Suddenly I am rolling backwards as engine is dead. I am still in drive, so I have to press the break to stop rolling into the car at the stop behind me! then I try to put it in park or press drive again, that doesn't work. I have to completely reboot the car by pressing break and pressing power button, then press drive. This is incredibly scary on the freeway because this was not as slow moving traffic as when the other situations happen (I.e. you are just pausing, not stopping long enough for autostop to do it's thing). D.repercussions: Seems that after the huge 'pop' one of the screens under steering wheel is not working properly. There is a blank screen instead of the 'home' one which normally shows things like your cruise control following distance/set rate. Also the buttons for collision and lane departure turned off and I had to turn them on manually. E.frequency: First happened Tuesday this week driving home from work, car had been parked all day, this was about 35 min into my commute., I called and made yet another appointment to have it looked at. Then it happened the next morning, was chilly, this time happened within four minutes of starting up. F.priority: I am extremely lucky I didn't have a fender bender either time. This should never happen, you should be able to trust that your engine is going to stay running. This will also get us in an accident.

We live in san francisco and do a lot of urban driving (aka, there's a ton of stop signs). When the A/C is not on, the engine turns off almost every time we stop. After owning the brand new vehicle for about a year, the radio and lights started turning off when the car would start back up at a stop sign/light. The power to the lights actually started to dim before they turned off completely. Eventually, the car failed to start back up on its own a few times. We took it in to the dealer and they replaced the starter under warranty. The problem went away. We're now 2 years + 4 months into owning the car and the lights are starting to dim again when the car is starting back up at stop signs/lights -- I'm hoping it fails again before the 3 year warranty is up so we can get it replaced again for free. This feels like a manufacturing defect to me -- one that's exacerbated by the frequency of stops in an urban environment and a starter that isn't built to withstand that kind of use. This should be investigated for a recall.

For a while now the car has had an issue with starting after the auto idle engine stop has engaged. It is slow to start, the radio and infotainment screen cut out, and there is a popping noise. When we had the car in for service last, we mentioned this and they said they couldn't replicate the issue and to record it happening. I'm supposed to drive around recording everything? this has progressed to the other night my wife was alone in the car and it completely died at a red light, with cars all around her. She was frantically trying to get it started after it said to switch to park and restart. It wouldn't start for 5-6 attempts and then finally started. This is extremely dangerous and to think it could happen with my kid in the car. We will be setting up an appointment to have it looked at again. Also, the shifting of gears in the car is rough between first and second gears. It's always between 25-30 mph when the hard shift happens. It's like the car doesn't know what gear to be in. Again, the dealership can't replicate it and we should record it happening. They did a transmission service as part of the standard mileage service recommendation and thought that may fix it. It did not.

The blue tooth features are not reliable. The feature that allows me to verbally tell the car to call someone is not consistently responsive. When I make a call from my phone, the car doesn't always pick it up. Incoming calls consistently come in correctly. I called van's Honda in green bay Wisconsin and was told that this is not an issue with the Honda and they recommended that I call the cell phone provider. They explained this is an I phone issue. Car is in motion. It has happened in my driveway, on city streets and also on the highway. Very unreliable.

I noticed that auto idle would randomly turn off and on the cars electricity for a second. Today, after stopping for traffic, the auto idle kicked in and the car stalled in neutral. Warning lights appeared and I tried to follow the instructions to restart the car, but it wouldn't restart. I was unable to turn the car off. I kept trying for about 3 minutes and finally the car turned of and I was able to start the car again.

Have a 2017 Honda Pilot touring with 39K miles. Usually the car goes into 'accessory' mode when the auto idle stop kicks in but a couple of months ago something new started- I experienced a total stall for the first time, and it has happened 3 more times since. The car turned completely off, but it did not restart automatically. The dashboard was lit up with problems. I put the car in park and frantically tried to restart it as I was on a highway in traffic. Once it was restarted, I disabled auto idle stop and I've been disabling it ever since. However, this is a manual fix and is not always something one remembers to do, especially since we have a new 16-year-old driver entering the fray in our home soon. After researching this extensively online, there appears to be a knee-jerk reaction from Honda to replace the batteries in these affected vehicles, but it is not stopping the issue, according to multiple accounts. The NHTSA has many documented cases of this and it is an obvious safety issue, but no recall is yet in place. Called Honda usa customer service at 9:30 am today and verified there are no recalls regarding this problem and if the car is out of warranty that there would be no financial relief for necessary parts/labor related to this issue.

The contact owns a 2017 Honda Pilot. The contact stated that the vehicle lost power while traveling on an incline. Also, the brake pedal was soft and traveled to the floorboard when being depressed. In addition, the collision and brake warning indicators illuminated. The contact drove to ryan Honda of minot (3701 S broadway, minot, nd 58701, 701-852-1111) to be diagnosed, but no failure was found. The contact also stated that certain electrical features on her vehicle sporadically failed to operate when needed. The manufacturer was not notified. The vehicle was not repaired. The failure mileage was 25,000.

My wife was driving the vehicle on 09-27-18 and the vehicle lost power, the dash lit up orange, and several warning lights cane on and started beeping. As she attempted to pull over to the side of the road, the issue reset itself, and the vehicle resumed power again. The vehicle was taken to Honda for a final repair for transmission issues the following day. It is 9 days later and the vehicle is still not repaired. Per the service advisor, the dealership has replaced 3 wiring harnesses under the dash that they say were defective from the factory, along with 2 modules. The vehicle is unsafe to drive in its current state, as it itermittently loses power. The vehicle had to be towed to the dealership in August due to the push button transmission going into neutral while driving, and losing forward power. The vehicle would not go into park or neutral.
