2013 ATS 2.0T AWD
If the car was parked for any amount of time, every time I start up and the first time I apply brakes at like 1mph, there's a weird fast double-click or mechanical sound coming from the rear. I've checked brake pads, body molding, etc. I hope it's not my differential. Rear shocks? Seems to emanate more on the rear driver side It's only when I first apply the brakes, happens both forward or reverse. Can't diagnose the issue. PS: 125,000 miles. Started at about 80k miles shortly after I replaced rear brake pads with OEM.
