just talked to the shop and they said they absolutely can not get it to replicate the problem so they are just going through everything and can’t find the issue they know there is one but can trace it down
Oven more a suspect of iwe. My 2020 does this occasionally, every 2 years, most noticeable in cooler weather on acceleration at hwy speeds. Both times, I replaced a check valve by the brake booster (p/n yg-360 on amazon), cured the problem. If it gets worse, likely it will, make another post, we'll help you troubleshoot it.
I have a 2017 f150 5.0 while driving yesterday it faulted out almost everything including airbag, park brake, trac control, service four-wheel-drive, ABS all on and saying error with the hill descent and lost all steering wheel controls.
I checked the battery voltage while it was running and got 14.3 Forscan codes Dash lights

so the shop called I’m going to pick it up they said they can’t get it to recreate the problem resulting in them not being able to fix it but this is all the dtcs when they scanned it (45)
I got both iwe replaced and that fixed the 4x4 issue but I’m still having the dtc problem with multiple codes coming up and resetting them and they come back. Finally broke down and took it to ford they were able to replicate the issue and are saying it is the yaw sensor. While sitting level and still mine is reading a 1.20 and they want $1500 to fix the issue. Does this sound right to cause all the issues above?
