Hi All,

Looking for some help with this grinding noise that happens when I start my '15 Tahoe LTZ. From what I can tell it only happens when the car is cold, if I run into a store quick and start it up after driving, it doesn't do it. Also, if I start it with remote start and let it idle, it still doesn't make this noise until I push start it and all functions turn on.

It's coming from the rear of the vehicle, thinking it has to be suspension related. I'm wondering if it isn't my Suspension Leveling Compressor?

Any thoughts? Appreciate the time.
