if all car manufacturers are not using the same management program for their Idle Stop system it's ridiculous to claim because it works great in your mother's Highlander then anyone that thinks the system in their car is faulty must lack common sense.
Woah there buddy. I never claimed any such thing. I'm simply pointing out that all these start stop systems are similar in functionality. And yes some the fault can be pointed to the owner. Even before this technology I (and many others) were using battery maintainers to keep our battery/charging systems in functioning order.

Bottom line is maintaining our batteries (regardless of brand) goes a long way to preventing a large number of failures that forum members are claiming.

I would never assume it is normal for a new vehicle owner to assume they are responsible to purchase a battery maintainer and to regularly attach it to their vehicle in order to avoid being stranded with a no start situation.

We purchased a Passport and assume our regularly driven new vehicle (still under manufacturer warranty & following all manufacturer recommended maintenance schedules) should be reliable and dependable enough to get my family to their local destinations without fear of break down or failure to start, period.

I cannot find any reference, requirement, or maintenance recommendation by Honda, either in their 600+ page Owners Manual, the 200+ page Owners Guide, or Honda site owners.honda.com that specifies the need or advises use of a battery maintainer in order to reliably operate a Honda vehicle. :unsure:

Note: I own both Noco Genius and Battery Tender brand battery maintainers, and use them during extended storage of our snowmobiles and atv, not on our Passport.

Don’t shoot the messenger. I’m only trying to help out the fellow owner with prevention tips I have learned over the years maintaining both personal and fleet equipment. The owners and service manuals are only to be used as a guide. Never ever are they to be considered the do all end all.

The start stop technology was designed to help meet EPA standards for ICE’s. It requires a lot of amps and even both a robust battery and starter will be hard pressed to keep up with the demands of the electrical system. That why it’s easily disabled with a simple push of a button.

Its good to know and I’m pleased Honda recognizes this by offering a simple software solution to disable the high draw components when CA’s in batteries are reduced. However, the owners can further improve their efficiency and reliability by keeping them topped off.

This actually explains something that I have been wondering about......I bought my 2019 EX-L in September. Never had any aforementioned troubles with the auto-start, however the last (cold) month or so, I have only been driving once or twice a week, and I am frequently getting the message, that the auto-start system is "unavailable". Apparently the battery is not charged enough to run it.....not a problem because I don't like it anyway, and this appears to be a built in safeguard against it not working and getting stranded at a red light......

Plus me too when it's been setting a day or two and used in a lot of local stop/go traffic. When it comes off the maintenance charger I rarely get the unavailable message and it works seamlessly.

I will respectfully have to disagree in regards to your arguments and rebuttals toward me. No vehicle is perfect. However, these Honda mechanical problems are getting blown way out of proportion. 5 NHTSA complaints (none for the stop start feature) for a 2022 Passport is not representative of the 10's of thousands that have rolled off the assembly line.

I'm not discounting the fact that there are a few of these having issues with re-starting in traffic. I will be in line at the dealer for the update if I get the letter.
Time to get in line . . .
Likely your 2022 Passport is one of the 10's of thousands that rolled off the assembly line with this same problem?? :unsure:

Does not worry me a bit. I already know what the software update will be doing. I knew before I purchased my vehicle what to do in order to mitigate the the issue. I'll have it in for my first free oil change and inspection soon. So it will be taken care of then while I have a coffee in the lounge.

I'm very proactive and like to solve potential issues before it becomes something that needs to be fixed.
