Throwing Codes

I have been putting off on addressing this issue for a bit now. My 2022 Bronco has periodically had issues with throwing wrenches and various drive train malfunction codes over the last 8 months or so. Been into the shop at least 4-5 times with no set culprit. Various fixes have been done that temporarily take care of the issue for a while. Increasingly I have been getting codes and Nag has been in the shop.
At the end of April and after a Baja trip, followed up with a two day trip up to Moab, it threw drivetrain malfunction codes in Moab and a week later in Arizona. Altitude always seem to be involved and the codes always went away and never effected the drivability of the vehicle. I took it in and the coil pack, plug and fuel rail on the #4 cylinder/drivers side were replaced.
A week and a half ago while driving my trailer to the RV store driving on the highway at 60 MPH, the engine light started flashing and it went into limp mode. I was able to exit and pull into the RV store. After dropping the trailer and getting the Bronco taken to the nearest dealership it was left for the experts.
After a week of changing plugs, same coil pack and fuel rail, along with internal inspection, the same issue arose. The new injector again was stuck in the open position flooding the #4 cylinder with fuel and fried injector, plug, and coil pack. They discovered that the PCM was bad. The PCM was changed and the engine got worse.
As of today it appears that the original PCM was going bad and was slowly shorting out the coil pack and in turn causing flooding of the system and gradually destroying the #4 cylinder. It no longer has compression in #4 and they will be running the scope down again and submitting the documentation to the engineers. Looks like it is time for a new engine.
Fortunately it will be covered by warranty.

So far so good, no additional codes have been thrown

Been waiting to update: So the dealership discovered that in addition to the above listed issues, the intake valve on cylinder #4 was cracked but the cylinder was not damaged. So they had to pull and replace the head along with the other items. After picking Nag up from the dealership, I noticed that at idle and with the AC running, there was a vibration coming from the engine compartment. And along with that the Auto start/stop would not engage correctly when stopped. Code reader said it was related to the #1 fan on the engine and that the start/stop was off due to high outside air temperature. Took it back again last Friday. On Thursday prior to taking it in I was going through the engine compartment and checking connections and disconnecting my fog light wiring harnesses and I noticed that the charge pipe from the air box to the passenger side turbo was not connected.
Yesterday I went to pick it up and they re connected the turbo and replaced both fans. Quite the ordeal but Nag is now running perfectly.

*wow*. that was quite the ordeal. Sounds like my on-going nagging issue with the A/C. Bottom line is that when I need it the most (i.e. when it's over 100 outside) is when it starts blowing hot air. If course I take it to Ford, and it won't do it so they can't figure out what's going wrong.

Good to Hear Nag is running perfectly now.
I just hope Elizabeth is up and running soon too. Yall will be missed at DV.

If you have a code tester throw it on and see what it says. Sometimes when it acts up with the AC it could be related to the outside air temperature sensor on the bottom of the drivers side mirror or the connector along the drivers side rail tucked into the upper fender area

That's the plan, I have a code reader, AND I have ForScan, just waiting for it fail again. It's just the other couple of times that it's failed have been during a run and I didn't take the time to throw on the code reader. But I think you're right, I have to jump on it next time it happens no matter what the situation.
