Check Engine Going On/Off

[Eusibius2]

Did you ever find a solution? What was the result? I had a funky, kinda similar issue. The Mgr for my dealers svc dept told me that all the U codes don't really mean anything, and always pop up all the time and that they're harmless. The P and C codes are concerning though. Like others have said, it could be a bad wire. In my case, it was one of the pins in the connector that was loose.

Transfer case & parking brake issues

I'm stumped on this one, and could use a little 'online support' to help make some sense out of this. Short story: 1. 2022 Z71 6.2L, 10k miles. Had it for 13 months with Zero issues 2. Heated Steering Wheel retrofit is finally available 3. few weeks ago, could not shift into 4WD HI (pic...

I'm sorry for such a late response but yes the resolution was just a bad connector. Such a simple fix solved everything. So happy it was just that.

I appreciate everyone's expertise on this issue. I am such a space cadet when it comes to cars.

Deja vu....‍

The engine light came on AGAIN. More lost communication codes.

it's going to be the same issue as before bad ground or connection somewhere.
things don't all go bad at once..... particularly when they are completely unrelated to each other.
if it was something like overtemp, hvac turned off, fan malfucntion, reduced engine power, etc those type's of things are all related to one thing.
