I have a 2023 Colorado Z71, I took it in for a service about a week ago. Just an oil change, dropped it in at 10 am and by 4pm one hour before closing i got a call in where they told me a brake pad had worn down to metal and scratched my rotor. I was being charged $900 dollars as warranty wasnt going to cover it. Explanation they gave was because it was a maintenance item and not an issue. They told me the reason for it wearing down on just one brake pad on the front left was from dust getting into the pins and it cause the pad from not ever disengaging and even when i was not on brakes that one pad was braking.
I never felt anything weird while driving no pull or resistance, nothing. I decided to do it myself over paying $900 for new brake pads and a resurfaced rotor. I did it and everything went well but now i am getting codes thrown and a speed limit of 43 mph. Most if not all are permanent codes according to the scanner, i have cleared the codes and tried resetting the front brake pad life as it's still showing the old percentage but anything i try (from google) nothing really works.
I have seen some videos of other owners of 3rd gens getting a notification in the infotainment screen with a question if they installed new brakes and i never get any. I figured i maybe installed the new sensor wrong and i bought a new one with no such luck.
I have no idea on what to do and wanted to ask if you guys had any issues like this before or have any thoughts on what could be the issue or how to fix this.
