I building a little info to take to GM, with the new 2021 full size with 6.2 , does it have the annoying chirp on start up and under light throttle,  truck owners are getting " they all do it so its OK" just curious if you Suv owners are getting the same run around, I appreciate your comments,  thanks

The engines are the same between truck and SUV. The start up oil pump sound if that is what you are talking about will be there is the cold months no matter what vehicle you have.

 

Not sure what sound you are talking about at speed under acceleration.
