It's just a button, you don't have to apply your 3 times ATF, OCD thinking when using it. 😆

Did I press the button or not?

We had that strange stall thing I time in our 2017 Pilot Touring. We're at 54,000 miles. It was strange when it happened and it seemed like forever before I could start it back up since I was in traffic. It's never done it since though....so I haven't been too concerned with it.

In my opinion/experience it's a software problem. I believe they check the health of the battery post auto stop, not pre auto stop. I haven't had anyone complain about this that anew battery didn't fix. Seems to me once the car shuts off, then the ecm checks the battery and sees it's not up to the parameters, then denies the restart. Why wouldn't you decide that before you shut the engine off?

I believe i checks the battery before auto idle stop, at least it’s the case in my Pilot. A year and a bit ago went to a dealer for this feature not working and they claimed that they charged the battery and it worked and charged me a diagnostic fee for the job. And auto start/stop worked for about a week after that until the battery charge worn off because of lack of long distance driving.

The battery has to be almost perfect. We have the same diag battery machine ( required Honda tool), have replaced many batteries that it passed to fix this issue.

The service information seems to indicate that the vehicle constantly monitors battery health by measuring "internal resistance, temperature, current, and voltage" and uses this information to determine:

• If the engine should be allowed to automatically stop
• If the engine should restart automatically following an automatic idle stop
• If the engine should be restarted manually following an automatic idle stop

Peoples driving habits have changed. With the advances in technology people have developed a greater sense of instant gratification, meaning that the see it, think it, want it, go get it. NOW.

As a kid on the farm Thursday, Thursday evening to be exact, was town/shopping day. The stores all closed at 5 pm, the grocery store at 6 pm every day but Thursday. Thursday the stores stayed open until 9 pm, including the grocery store.

The town folks bought groceries etc, usually on Saturday, but for the farm folks Thursday was shopping day. If it want an emergency, you didn't go to town to get it, you waited until Thursday. It was also the day that the A&W and the Taste Freeze had the most help.

For me/us that means Friday is my shopping day these. I get groceries that day and do any other running I need to do. I schedule as many appointments for Friday as well. Saturday is the alternative shopping day when the wife and I have something to shop for together.

Now short trips are the norm, to the detriment of vehicles that have newer, high load batteries, in vehicles that put higher loads on the charging system, that has a slower charging rate then the old flood acid battery days.

It does but, to me it appears to have some flawed logic. If it worked perfectly, it would know BEFORE auto stop the battery was compromised, or didn't meet the programmed standards. When I get one that I can reproduce the failed start, the log shows sub 9 volts on the attempt to restart. Replacing the battery cures the issue, even though the veh battery monitor and the battery diag machine say the battery is ok.

If it were my elite I deactivate that feature permanently. There’s a mod floating around here somewhere.

We started having quite a bit more problems with our 2017 Touring stalling when it was going to the auto start/stop. Ultimately took the vehicle to the dealership for a new battery and this appears to have resolved the issue.

No more popping from the radio when it transitions on the start/stop. They quoted me $195 for the battery, but then had to come out to tell me that it was an AGM battery and was more expensive. I was like, I knew it was an AGM battery, how did you not know when you quoted me.

Sorry to revive such an old topic, but we are also experiencing the exact same problem in our 2019 Touring. Our Pilot is still under warranty and we mentioned the stalling to our dealer during our last service visit in August, however they were not able to duplicate the issue (of course). The stalling appears to be happening more and more, so I just sent an email to Honda explaining the situation, and I am still waiting to hear back. Have you had any issues since you got a new battery?

Just so everyone knows, I did more research and found the following info from the NHTSA:

^ That issue was related to a condition where auto idle stop would not stop the engine - not a condition where auto idle stop would fail to restart the engine.

I have a 2016 Honda Pilot and have experienced intermittent stalling after coming off the brake at a stop (including 3 times in the past 7-10 days!). 95% of the time it works fine but when it fails and I stall in traffic from a stop, it is nerve racking! I am proposing a way for all Piloteers to remember to push the deactivate stop start button. I propose this as a way to help us all cope with the problem until Honda can fix it if ever. Here is my temporary fix; it’s not pretty but I think it may work. You can be creative with it. I hope it helps at least one other person if not more…

Yes, I had product software upgrade done I believe in March of 2023. My 2016 is the Elite Pilot trim which I forgot to put in my original post. Thank you for the info, however. The problem has me feeling desperate at times so today I came up w my silly by hopefully effective reminder to deactivate system manually each time. I think it’s so stupid that dealer won’t deactivate it for safety reasons (stalling in traffic). What I got from your info is to try to push park button first if I read it right to best restart the vehicle. I feel the brake feeling strange at time of stall. Most times stop start works fine but I’m tired of dealing with it. Thanks..

Although yours doesn't qualify for the second part of the TSB, I wouldn't be surprised if the same issue was at play. Also, if you really don't want the system to be active, consider installing Idlestopper:

Turn your auto idle stop system off automatically on your Honda or Acura vehicle with the Idlestopper. Disable Idle Stop System

Our 2019 Pilot Elite with 51,000mi had the "update" a few month ago. Previously it failed to restart a few times in traffic. I thought I would wait to post after a few thousand miles of observation. From my perspective, the update was minimally effective. Still a weak system with a noticeable delay. If your battery is healthy (i keep ours on a tender if it sits for a week) it works ok. The question is still is the system which is not up to par killing the battery and starter early? 5-6 year Batteries dying in 2-3 years is unacceptable. And, if it is the system then Honda nees to replace the sytem and the battery.

 

[Karl2020]

Is there a way to tell WHY the autostop did not work? I have the idlestop mod installed and it works well. But once in a while when I want to play around, I just turn it on. Had the fix done by the dealer back in January. It has not really worked. So kinda want to know WHY its not activating.

It’s just not worth having it activated. I doubt it saves gas AT ALL. I doubt it cuts down on pollution but I can’t prove that and I’m sorry but I’m not willing to risk my safety. Give me a reliable system and I’ll use it. I posted my makeshift car reminder on how to deactivate it every time yesterday. I drove it this morning and there was no drama with a deactivated stop start system!! Good luck.
