On 5 occasions since purchase of 2019 PP, the car has not restarted after removing foot from break with "shut down" activated. On most occasions there is no msg on dashboard. Also, transmission shows N and start/stop accomplishes nothing. The last time this happened I was in stop and go traffic on I35 during rush hour traffic. Finally, a msg came on dashboard with "accessory mode". Eventually, I was able to get it restarted after 2-3 minutes, but not immediately when it happened.
Honda dealers have not found anything in car computer that this happened.
Anyone experienced this or has suggestions

NHTSA is investigating the start stop issue in several Honda vehicles which includes the Honda Pilot from whose parts bin Honda built the Passport. Several members of this forum have experienced the problem you described or a version of it, searching "battery" here will get you a deluge of problem threads. The issue is basically an inadequate battery problem, Honda seems to have shipped many vehicles using it's start stop system with batteries that can't hold a charge or cannot handle the strain of repeated restarts.

Try manually disabling the Idle Stop system every time you start your car with th button on the center console. My wife drives the Passport we own, I installed an Automatic Idle Stop disabler for her because she forgets to disable it. Since the battery in your 2019 Passport is a few years old now, you should also consider having it checked and replaced.

I am currently on my 3rd battery. First 2 were under warranty. Third one is a 10 year battery. Does the CRV also have this same problem?

Interesting that this happened on the 3rd battery, perhaps this isn’t solely a battery issue and is this 2nd variable as wide spread? Hopefully Honda can get this figured out, Love my PassPort and would hate to see them lose the reliability reputation.

A couple of questions if I may. What are your driving habits?

Do you make a lot of frequent short little trips or do you most often drive the vehicle for 20 minutes or more at a time?

Are you driving in a lot of stop and go traffic?

Battery health, especially AGM battery health can have a lot to do with a persons driving habits.

Happened to me once, talk about panic when you are sitting at light and wondering what just happened? I drove from Charlotte to Raleigh NC - stopped for gas and boom at 2nd light after leaving. Cars honking and wondering what was going. No error messages so nothing helpful to diagnosis. Finally broke down and ordered auto idle stopper so hoping that solves any further issues. No battery issues I can tell and I had just driven solid distance for battery to be fully topped off. I generally try to hit the button to shut off but don't drive enough (working from home) to make it a solid habit. Maybe Honda can send me $85....

Other forum members have reported similar experience, the car starts when they left home, they drove for several miles or for a duration of time that would have had any healthy battery fully charged up by the alternator, but they stop to pick up groceries or something that takes just a few minutes, return to the car and boom it won't start until they got a jump from another vehicle. Makes me think that regular driving or lack of it is not the core reason the vehicles battery fails to start the vehicle.

2019 Touring with 30k miles. Combination of local and freeway driving. After running errands a few weeks ago PP failed to start after the last stop. No prior starting issues. AAA tech could not jump from his jump pack, from the truck battery with engine running, nor from a fresh battery from his supply. Finally had to connect two fresh batteries in parallel to get the PP to start. Drove the three miles home and the PP started fine. Could not get it to fail. Decided to get a new battery. Dealer wanted $350! Costco has an Interstate AGM with higher Cold Cranking Amps than OEM for $180. So far working great.

This is the type of thread I was looking for today. 2019 Passport Touring, now we've had 3 no-start issues recently. The last two were this weekend and today. On the weekend (Sat), drove about 100 km, got home, unloaded the car and went to re-start it, dead, won't start. Took the other car, didn't boost it. The next day (Sun), Passport started no problem on it's own, no boosting, no nothing.
Next day (Monday) Passport starts fine, wife drives to work - 35 min away. At lunch, goes to leave,Passport won't start.

This can't be a battery issues, and batteries don't magically recharge themselves sitting in the driveway without the car running.
There must be a bad connection, or some piece of software preventing it from starting...

Anyone else having this issue, i'd love to hear your stories...

Swap starter relay with something else similar in the relay such as AC compressor.

For piece of mind, I'd just go ahead and replace the battery with the Interstate AGM that Costco has for $180. I have had zero issues re starting after replacing the battery. This is on a midyear '19 with 30k miles.
BTW, over the decades I have have batteries that would not start a car but would after sitting overnight. I am not any sort of battery expert, but it seems Ike the batteries have just enough power to start the engine after sitting overnight. In every case I repla ed the battery. Many shops such as O'Reillys will test your battery at no charge.

You experience is familiar, @Tadakatsu reported a similar experience in the thread below, several other members have reported similar experiences too - vehicle is driven several miles, parked for a few minutes and it won't start when the driver returned. Also in several of these incidents the vehicles starts without a hiccup the next day. All these seems separate and distinct from the Start/Stop failure to restart issue.

It's a situation of particular interest to me and I'm beginning to agree that indeed there may be an undetected gremlin in the vehicle's starting system.

I have 19k miles on my ‘21 Passport, and tonight while pulling out of the hospital parking lot, the auto-stop kicked in as I waited to turn out onto the main road, then she wouldn’t start back up. Battery lights came on, she just went dead. Nothing but clicks at the restart attempts.

The reason it was a bad time and made it annoying, was:
1) It was dark at night
2) My son was having an allergic reaction, I forgot his epi pen, and had pulled into the ER parking lot on the way home. Gave him Benadryl as we have a few times which usually works, it worked, so we headed out, but still needed to get him home to settle down, and then boom, it cut out dead soon as I got to hospital exit.

My kids are now crying as my son thinks he’s dying, but I popped the hood, hooked up my GB40 battery pack, started the car back up, and drove home.

Idle stop is terrible for me personally. It doesn’t just leave you stranded in a parking lot, it can die on you anywhere, turning like I was, waiting at a red light (as it almost died last month but battery checked out OK), etc. Luckily I wasn’t at a red light this time which would have been even worse.

So… idlestopper has been ordered and I’ll be installing that… along with a new battery apparently.

I have an irrational fear of the thing not re-starting, couldn't imagine that along with what you were going through. That sucks and I'm glad everything is okay. I don't normally do or like modifications, but idlestopper is amazing and easy to install.

What battery you going with? The Honda ones are junk and I don't even want to bother with it. I can't get it to fail on our tester either which is required for warranty. Keeps saying its "good, needs recharge" then I let it do its 2 hour recharge... week later I start getting slow/extended cranks again with flickering lights at cold start.

I went with a Duralast in my wife’s car recently, but am going with a Napa Legend Premium for my Passport. I would get Costco Interstate due to price, but they’re all out of stock, and not super close to me. Autozone and Napa are just the best auto parts places near us. I hear good things about Walmart Everstarts, but it’s such a pain going to our Wal-Mart so I ruled it out for that reason.

If your battery dies, not sure that having idlestopper would help, would it?

A battery only has x number of starts/cranks.


@REALM . Glad your family is doing better!

I hear you about walmart, hate that store! I do get their everstart battery due to video i warched from project farm on youtube. The guy does great detailed videos about all kind of things and rated the everstart as the best battery for your money. Good luck and glad your Son is ok!
