Car was fine all day. Parked with the engine shut off for two hours whole I was waiting for my kids. When I picked them up and started the car, it has a warning. My 2017 Honda Pilot only has a little more than 38,000 mi and now it's saying "keyless start system problem". I have read a lot of articles with the 2016 and 2017 Honda Pilot having the same problem. The problem persists even after I changed my battery for my key fob, thinking it could have been the problem. I tried both key fobs, problem is still there.

The engine with shuts off normally when I come to a stop when I have the system engaged. The problems begin when I take my foot off the break expecting the engine to start up again. What happens consistently (though not all the time) is that when I take my foot off the brake, the engine shuts off, shifts itself into nuetral, and I have trouble getting the engine to start up again. This occurred two separate times. I brought the car to the dealership and they can't find anything wrong with it.

When my 2017 Honda Pilot touring enters idle stop mode, it has begun to stall when you release the brake to re-engage the engine. This happened first in a parking lot on 6/17/20 when leaving parking area to enter main road. Vehicle shifts into neutral. Must put it into park. Then hit start button. Then put vehicle back into drive. Took it to dealership (under warranty) on 6/23/20. Could not duplicate problem, but identified codes: P170B-dog clutch a abnormal operation, U0230-gauge lost comm w/ptg, U1281-gauge lost comm w/micu, U0199-micu lost comm w/master switch, U0180-climate control lost comm w/master switch. Technician noted in report that they inspected the freeze data, trans had no input speed, so code must have set during an idle stop. The technicians could not replicate the problem, so they reset the code and asked me to bring the vehicle back in if it happened again. While driving on the freeway on a bridge crossing the columbia river on 6/23/20, this happened again. I was in stop-and-go traffic in the center lane of the bridge. After one of many short idle stops (engine off for about 1 second) I took my foot off the brake and the engine stalled. Same issue. Shifts to neutral. Must put in park. Hit start button (twice). Engine starts. Shift back into drive. Took 30-60 seconds while traffic tries to maneuver around me. Lucky I was in the middle of the queue (not back) as taking my foot off the brakes would imply to the driver behind me that I will be moving again. Definitely a safety hazard that could ultimately lead to injury/death. I returned the vehicle to the dealership again. They did not find any codes this time. Tried to return my vehicle to me without doing anything. I argued per my previous visit that they had reset the codes and asked me to return if this recurred. Awaiting resolution.

While traveling South on I-95 from baltimore, md to Washington D.C., near kenilworth avenue, the engine idle shutoff on my 2017 Honda Pilot touring engaged when I was forced to stop due to a traffic slowdown. When I took my foot off the brake, instead of restarting as it should have, all of the warning lights came on and the engine stalled. I shifted into "park", engaged my emergency flashers, and attempted to restart the engine several times without success. While stopped, I was nearly rear-ended several times because traffic started moving as soon as I took my foot off the brake. I was in a center lane and unable to exit the vehicle or move it from traffic. I was finally able to get restarted after a few minutes and several more tries. I had previously had the vehicle in for issues with the engine idle shutoff and the dealer had replaced the battery, which I thought had fixed the problem. When I took it in this time it happened they say the battery is good and "cannot duplicate the problem". there is a broad base of internet postings for this problem on 2016 - 2018 Pilot elite and touring vehicles, with the 9 speed transmission. There is no way to permanently turn this feature off and I believe it represents a serious safety hazard, especially for highway travel.

For roughly the last 4 months, my car stalls at a stop (stop sign, traffic light, etc) by shifting itself into neutral. The car has a push button gear shift and the warning light says to shift the car into park. Sometimes, I can shift the car into park and sometimes I can't shift the buttons at all. If I am able to shift into park, a message on my dashboard lights up and stays 'to shift from P, engine must be running'. either way, I have to turn my car off and back on again in order to be able to drive. The first time this problem happened, I called the dealer and they thought that possibly something got lodged in the gear shift. However, as time goes on, these events become more and more common. Our local Honda dealer had my car for roughly a week in June and tried to recreate the problem. They were unable to duplicate it and did a factory reset. That worked for about a month. Now, the stalling happens at least once a week and yesterday it happened three times in the matter of an hour. When I took the car to the dealer in June, it had also stalled three times in an hour. I feel at high risk driving the vehicle because cars get impatient behind me and start moving when the light turns green even though I can't move. Or, if cars are approaching a green light, they probably won't realize that I am unable to move making this a huge safety concern. This problem happens everywhere but on the highway.

Smartphone linking functions defective and disconnects while operating vehicle, causing a driver distraction with loss of navigational functions and loss of hands-free phone operation. Has been in to dealer for this condition multiple occasions. This condition most often occurs while vehicle is in motion. The audio system loses ability to adjust volume, causing a danger to the driver who is unable to turn down the audio volume. This is a safety concern with the vehicle that is unresolved.

Warning light "keyless start system problem." The system error warning light comes on and off. No other issues noted. I've been reading many blogs and reviews on this issue. My concern is that my car will stop while idle. I want to make sure the proper Agency is alerted to this issue in support of a recall.

The auto idle doesn't always re engage when at a stop light. Very scary. Worried about being hit from behind.

Keyless start system problem

- Parker, CO, USA

I was stopped at a stop light and my auto idle kicked in. When I took my foot off of the brake the engine died and wouldn't start back up. I was stuck in the street, blocking traffic. I tried to restart the vehicle multiple times with no success. After the tow truck arrived, the engine was jumped and I drove it to the dealership. Battery was checked and it was fine. They have been unable to repeat the problem.

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.
