I want through the same issues, 2 trips to the dealership and it's solved. They have multiple MOST connectors and I'm told they are very sensitive, not sure how many there are, and I'm perplexed by Honda for not issuing a recall, but they dod extend the warranty on this problem for an additional 5 years or 60K miles, and will reimburse anyone for previous monies spent to repair...so it sounds like a recall, but the owners have push for repairs.
Hope it will work out for you .. keep us updated ... too early to saying anything yet ..
We purchased a used 2019 passport and had the same issues. We were told it was the same issue as yours the bus connector to the stereo, after many attempts to replace tweeters, new bus connector replaced twice once with us owning it and the prior person who leased it. We'll after nagging at them to get this vehicle fixed or I want my money back. They replaced the main wire harness throughout the entire vehicle. After that problem fixed. You might to check your warranty on your vehicle and ask them to replace it.
I have a 2021 EX-l with 20K miles, this issue just began this week. I am have an appointment next week to address the issue, they seemed well aware of the service bulletin (20-058) and said they had the parts in stock.
Yep, it should have been addressed a long time ago. As long as they fix it, I'm good, I didn't want to have to debate with the service department about whether it was legit. Mine came out of the blue and is really noticeable, whether the stereo is on or off, so not much room for debate. The service department asked me no questions and immediately scheduled the appointment. I'm guessing that this is becoming really familiar to them.
The attached TSB is from September 2019, it indicates Honda is aware of the MOST failure even before that date so I'm also wondering why Honda allowed 2020 and 2021 vehicles to leave the factory with the same problem. That to me is General Motors behavior territory.
Not sure about 2020 as it is pretty close for new model to hit production lines.... Certainly, the "fix" should have been in 2021. Only reason I can think off is that there is no "fix" and Honda is throwing darts, replacing wires/parts to make people feel better.
I thought that after the Passport Assembly line reopened AFTER the COVID shut down, there were a certian number of new/inexperienced Assembly Line workers, that may have contributed to a number of reliability issues appearing and/or reappearing...
Well they have been back at it for a year now, I do recall hearing about problems with the early ones made after the re-start...
Probably not enough units with problems to formally make a recall but, there is the TSB which addresses the issue, if you have the problem. I think that's sufficient for now.
