Not on my daily, rather my dads, a 2019 Honda CR-V with a 1.5l turbo engine. About a year ago the dash would go full Christmas tree, warnings that everything has failed. At the time there was two issues, one is my dad had spilled oil when filling it up and soaked and killed the alternator, I replaced it with one he got at Advance Auto, that was junk and failed in a week or so, was able to have a dealer re-replace it with a genuine part under the extended warranty he has for the car. At the time that seemed to satisfy the car enough and did not do the Christmas tree dash again until just a couple weeks ago. Well in my initial research on the Christmas tree dash many forum posts detailing that same issue ended up with the replacement of the fuel injectors. On vehicles only a year or two old, 20-50k miles, not 450k mile beaters. I had mentioned this to dad but he kind of brushed it off and so did I as it was fine until just recently.
So with the scanner hooked up I saw that cylinder 1 and 4 were counting misfires, so I swapped coils 3 and 4, the misfires remained on 4, ruling the coils out, put new plugs in it (it was ready for them anyway, interval is 100K, his is at 107K) that kind of, but not really helped, still counting misfires, but "B misfires" a road test showed them counting up on decel, not under load, the short drive cylinders 1 and 4 had counted over 100 B misfires.
It took some convincing, but I was able to convince dad that it probably, like all the others I've read about, needed injectors. I also had to make clear I was going to only install Honda injectors/parts, and I would not do it with anything else, I just do not trust part stores for that kind of thing, and in reality the cost for the Honda kit was somewhere between $30 more and actually a few hundred potentially less than piecemealing it together using parts stores/rock auto. Got them ordered and received a few days ago and decided to do them today. I also had dad get a 1yr subscription to Mitchell1 diy for the service literature, and I was able to get an intake gasket set in at the Oreilly's by the shop.

New Honda parts, this part number is one or two revisions from the original numbers the car would have had, there must have been some mfg change/issue or something. 4 new injectors loaded with the seals, 4 new clips, and one new high pressure fuel pipe. The fuel pipe, like the newer LS engines with the DOD/AFM and spider injection lines is a one time use deal, so it needs to be replaced if removed.

Intake had to come off, throttle body moved aside. This car uses a "low pressure" lift pump in the tank to bring fuel to the high pressure pump that is driven off of the intake cam, sending fuel to the rail, almost like a common rail diesel in a way.

Took about 3.5hr, the book time was 3, so I guess I did ok for this not being my normal sort of work. Couple of ignorant to get to bolts, but not horrible. Got things buttoned up, codes cleared, fired up and idling good, took it on a road test and no misfires being counted, drives good, no leaks, I'm calling it done and good to go. I sure hope.
