This is also happening in Singapore, apparently all Fit/Jazz, Vezel/HRV, Freed are having injectors problem. A mechanic told me to avoid Honda Vezel, I did and thought I should then get a Freed only to find out from Freed community someone had to have it replaced at 30 000km, not covered under warranty. And we don't even have any TSB here as the govt her does not prioritise safety the way it is in USA.
This is my 5th but will be my last Honda given how they ignore this problem.

I'm sure we'll never see the numbers, but really what is the failure rate of these injectors? If Honda sells 50k units in the US, how many of those actually have failed injectors within 5 years as an example? Obviously no one wants to have that happen to them, but really what are the chances?
I've got a 2015 with 84K and touch wood, so far so good.

What's the definition of large number? The 2016+ got different injectors, but I've still seen on the forums GKs of that vintage fail. Doesn't seem to have been fixed. Has it been lessened? Don't know that either.

Two questions.
"You should be running fuel injector cleaner"
OK....I occasionally run a treatment of Techron just as ritual. I've done it with every vehicle I've owned. I also usually, predominantly fill with top tier gasoline.
However my understanding is with the Direct Injection engine of the Honda Fit the gasoline is being injected after or below the injectors, which is why carbon builds up on the top of the injectors...no gasoline, is sprayed on top of the injector, making it more fuel efficent but the injectors become more susceptible to carbon build up on the top.
IF big IF this is the truth and my understanding isn't flawed, then it would seem to me running a fuel injector cleaner wouldn't matter. It's not going to reach the problem area. So the solution isn't as easy as just running detergent gasoline, and fuel injector cleaners. Is this correct thinking?
The other thing I'd like to know, is I occasionally hear that Honda made a change to address this problem in "Early 2016".
First of all, is this true? Has that been confirmed?
And Secondly, since I have a 2016, is there any way to know if mine is a pre-fix 2016 or a post fix 2016?

You're mixing up two completely different problems: fuel injector failure, and carbon build up on valves.
The fuel injector failure problem occurs on 2015 and early 2016 models and apparently occasionally on 2018+ models. It has nothing to do with carbon build up although Honda has never given any explanation that I've seen other than the injectors fail and have to be replaced.
Carbon build up on valves is the other problem, an almost non-existant one. People on this forum and elsewhere talk about it a lot but virtually no one has ever experienced it. It's the classic bogey man that everyone is terrified of but no one has ever seen.

2018 Honda Fit
Last summer the check engine light went on in my 2015 Fit. Honda found code P0420 and told me I needed a new catalytic converter. It wasn't a big deal to me at the time because it was entirely covered by warranty.
Now less than a year later, my car has a misfire, the light goes on again. Honda finds the same code, but now there is a TSB suggesting that the issue is actually fuel injectors. I am 5,000 miles out of warranty on them and it's going to cost me $2,000 to replace it all. Has anyone else had these issues?

Catalyst not ready, 2011 Honda Fit Sport
Hi guys! Wondering if anyone can help 🙏
My car was sitting for a couple months and the battery died. I got it jumped and then a few weeks later wbet to get a smog test. Came back that the catalyst is not ready. No check engine light. Car has 185k on it, drives amazingly still. From the smog test, I've driven 1k miles, and have done two cycle tests, and used cataclean. Still not ready! Any ideas???

I don't know if you heard, but a lot of 2015 Fits had bad injectors. Honda denied it for a few years, but they seem to be doing "something" about it now. The warranty has been extended to ten years.

I'm finished with Honda, too because they stopped importing the Fit, in favor of the more profitable HR-V.

Yes, direct injectors can cause problems, but my 2015 is doing okay at about 82,000. Try Seafoam or a similar product. Do a search on YouTube for it. I've never used it, but I have a can in the garage.

I have a 2016 (137k miles) w/ the dreaded P0420 only. My mechanic brought service bulletin 22-002 to my attention. I checked my inVin and it did not pull up for my car. My Honda dealership said it would not be covered but that they would make note of the bulletin on the service order and that it would be up to Honda USA discretion on whether any of the charges would be covered.
SO my question is does anyone have experience with something like this? Is it worth even going to the dealership. Should I just let my mechanic fix it. Emission test is due in a couple of months. Thanks!!
