I have a 2021 Silverado 1500 LT I purchased last April 2022 (during the vehicle/chip crisis)

I had ticking sounds starting at 4k. I asked dealership where I purchased about the ticking sound on my first oil change - no problem they said
Fast forward to around 12k - major engine banging sounds!
They told me it was a known issue and would be repaired under warranty - yeah you think!
Replaced right side - lifters; push rods, and injectors!
I found that issue out after researching "known issues"

I'm at 27k and the whining I'm hearing is now another "known issue" with a pulley I think they stated - will be repaired next week under warranty

with all that said, where is the best place to research "known issues" so I can try to stay ahead of the issues per say?
First and last chevy here

You can also find recalls and other information on the NHTSA website -

Keep in mind it will probably take some more time before other issues are reported (regardless of the source) - the 2021 models are a new generation of truck (body and drivetrain) so these first few years will be a matter of data collection with investigation as needed.
