Please Post Honda Service Bulletins Here (Passport related)

I thought it would be nice to have a thread that collects al of the known Honda Service News Bulletins.

That way people with issues could read up on them and be more informed when they go to the dealer and not have to settle for the typical Gober Pyle answer of "Gee wiz, never heard of that happening before"...

In order to stay focused on the Service Bulletins, I'm kindly requesting that ONLY Service Bulletins (or their numbers) be posted in this thread, it's perfectly ok to add comments along with the Service Bulletin, but if you want to discuss them, please do it in another thread (or make a new thread - they are FREE!). And don't be too put off when I delete the posts from those trying to discuss the Bulletins.

TSB 20-097 Continental Tire Recall:

A very limited number of 2019–20 Passports may be equipped with one or more Continental Cross
Contact LX 245/50R20 102H tires that were cured for a time beyond the specification limits. Over-cured tires may develop
a break in the sidewall resulting in sudden air loss or a belt edge separation, which could lead to a tread/belt loss.

TSB 16-054 Engine Noise after engine warms up

    • 2019 Passport models
    • Timing belt area makes a chirping noise after the engine warms up for 30 minutes
Thank you! Any way we can listen to the chirp?
If anyone purchased the running boards with lights they will install new upgraded ones for free. Honda has released a service bulletin for this product. I have only had mine on for 2 months and already 3 out of 4 lights are out. I really like going back to Honda and waiting for 2 hours for light bulbs installed.
Not actually a recall, but this and many other TSBs are listed by in another post. TSB 20-022
Don't know how @P-A-N-D-A gets all that inside info, but glad the bear shares them here.

TSB 23-008 Product Update: PGM-FI Idle Stop Software Update (2019-2022)

BACKGROUND

Under certain circumstances, after coming to a stop and the idle stop feature engages, the vehicle may not automatically restart. Typically, the customer can immediately restart the vehicle by selecting Park and pushing the ENGINE START/STOP button.

CUSTOMER NOTIFICATION
Owners of affected vehicles will be sent a notification of this product update. Do an iN VIN status inquiry to verify eligibility. Some vehicles affected by this campaign may be in your new or used vehicle inventory. Repair these vehicles before they are sold.

TSB 23-010 Warranty Extension: Engine Does Not Auto Restart After Entering Auto Idle Stop (2021-2022)

Owners of 2021-2022 Passports also receive extended warranty coverage for valve adjustment to 10 years from the original date of purchase with no mileage limitation.
Owners of 2019-2020 Passports receive Honda's extended "Go Pound Sand" warranty.

At least there is something useful for D-I-Y mechanics included in the A23-010 Service Bulletin.

23-009 Starter & Valve Adjustment Warranty Extension for 10 years
2019-2020 Passports that received 23-008 Software Update
It is dated Jan. 6, 2023. Has anyone with 2019/2020 Passport received this warranty extension notice.
I printed it out and put it in my Passport paperwork in case Honda service develops amnesia about this 7 years from now.
