My wife has had the car the past few months and has been picking me up from work. I noticed something loud today, like something dragging under the car. I noticed it the minute she pulled off. I asked if she hit or ran anything over and she said no but she also noticed that it was a little louder the past few days. I rubbed my fingers across the rear rotor’s and they’re both gauged. I have a 28kwh version with 50000 miles. Has anyone had a rear brake issue? I don’t feel like they’re hanging up or anything. I’ll hear a loud bang sometimes if it’s really cold (like single digits) from the parking brake. I feel 50000 miles is way too soon for rear brakes on a EV.
