I have heard people on here had rod knock issues. I think perhaps the passport was not sold large enough quantities so Honda is just doing case by case instead of issuing a recall.

The investigation lists 2016-2020 Pilot, 2017-2019 Ridgeline and 2018-2020 Odyssey as affected by the engine issues but no 3rd gen Passport.

Yet...

The part number for the 2019-2024 Passport's cylinder block is 11000-5G0-A11 - Same part number for 2016-2022 Pilot, 2017-2024 Ridgeline, 2018-2020 Odyssey.

The part number for the 2019-2024 Passport's cylinder head is 12100-R9P-305 - Same part number for 2016-2022 Pilot, 2017-2024 Ridgeline, 2018-2024 Odyssey.

Specific components made be manufactured at different times but I know if the part numbers are identical, then the parts are identical too.

Identical implies ALL the parts are the same not just some, just as there is a difference between Identical twins and fraternal/dizygotic twins.

Possibly because while the are in the same J family of Honda engines they are not exactly identical.

What parts used on the J35Y6 between the Odyssey, Pilot, and Passport aren't identical?

You are splitting hairs at this point...Not surprising though.

US probes into more than 1.4 million Honda vehicles over engine failure

US probes into more than 1.4 million Honda vehicles over engine failure


Aug 25 (Reuters) - The National Highway Traffic Safety Administration is opening a probe into more than 1.4 million Honda (7267.T), opens new tab vehicles sold in the United States over concerns that connecting rod bearing failures in their engines could lead to complete engine failure.
In a letter dated August 20, the regulator said it received 414 reports of the issue in various Honda and Acura vehicles' 3.5-liter V6 engine.

The investigation covers 2018-2020 model year Acura TLX, 2016-2020 Acura MDX, 2016-2020 Honda Pilot, 2018-2020 Honda Odyssey, and 2017-2019 Honda Ridgeline vehicles.

In 2024, the agency probed 1.4 million Honda vehicles on reports of serious engine issues following the Japanese automaker recalling 249,000 vehicles in November 2023.
Honda issued the recall to address a possible manufacturing defect in the engine crankshaft which could cause the connecting rod bearing to prematurely wear and seize, leading to engine failure.
The U.S. auto safety agency said in the August 20 letter it is opening another investigation to more thoroughly evaluate the scope and severity of the potential issue and to fully assess related safety concerns, following the closure of its previous probe.

NHTSA said that the high volume of engine failure reports in vehicles not covered by the previous investigation poses a potential safety risk.

Thanks, we're all well aware of the probe. Run-a-long now....

oh, I just saw they start new probe like 7 days ago and passably adding Passport to it.

No mention of the Passport in that article.

In some ways maybe, but there have been 24 variations of the J 35 engine that has been introduced/manufactured/utilized by Honda. They do not all have all of the exact same parts, nor I suspect, are all of the parts in the various reiterations of the J35 engines all produced by the same manufacturer over the course of those 24 engine variations. Specification for those various parts may well have changed as well. The J35A1 calls for a 5W30 oil with an SPI classification of SJ. The J35Y8 calls for a 0W20 with an API service SN or higher grade, API Certification Mark “Starburst”.

They are all similar as are their cousins, the J25's, J30's, J32's and J37's. A minor change in specifications, materials etc. can have varying consequences. If the engines are all the same, why did this problem not come to the forefront after 1998 when the J35A1 was first introduced and put in the 1998 Honda Inspire or the 1999 Acura TL & CL?

The fact that multiple vehicles share the same engine replacement part number would indicate that the same iteration of the J35 engine was installed in them. Using Honda data, the part number of all J35Y6 engines is homogeneous and clearly different from the part number J35Y8 engines.

We're not talking about every iteration of J-series V6 built. The investigation only includes the J35Y5 (MDX) and J35Y6 (Odyssey, Passport, Pilot, Ridgeline, TLX). The Y6 used between those 5 models are identical. Why the Passport wasn't included? Who knows.
