2009 Silverado Hybrid Transmission
It's got a crazy rattle on cold start up, whining between shifts and on really cold mornings it has to warm up or it won't move.
you probably have some "noise" leakage into the 12volt system making the speakers audioable as they are "always on" (as they do BCM sounds)
check the ground wires for damage,dirt or corrosion..
normal for a CVT (same for reverse as it's CVT ) just back it in at night and put it in M to go forward
what about M4 mode?
those sound like pretty normal things

you know the target market for these hybrids were California not where you live
as you can see nasty stuff builds up on the wires and cause trouble for you there is also a hidden ground wire behind the inverter besure to disconnect the power lines before cleaning them...
Don't touch the orange cables if those are dirty they need to be done by a Pro. as they contain high voltage
