Owned multiple new vehicles over the years, Per the dealer Its not a serpentine belt noise, they said it’s a starter noise when cold ( normal ), just disappointing To hear the chirping on a brand new truck.

I have a 2019 GMC Sierra 1500 Denali, just over 4000 miles, on startup I keep hearing a chirping sound similar to a slipping belt, very noticeable on auto start /stop, dealer said it’s normal, pretty annoying on a 65k truck. any ideas on what’s causing it.

Same chirp here on cold startup then goes away when warm, dealer said its normal, pretty annoying.
