How to fix CT4V BW brake vibration?
I recently purchased a 2022 CT4V BW with 22k miles on it from CarMax. As soon as I drove it off the lot, I noticed significant brake vibration (felt in the seat, not the steering wheel) when braking from speeds above ~65 mph, which is obviously a tell tale sign for warped rotors.
To be sure, I did some research, and found that these brakes often need to be burnished if the car has been sitting for a while. I tried doing the burnishing myself by braking hard from 60 mph to 0 mph 10 times with ~1 minute between each interval. That didn’t help, but perhaps I didn’t do it correctly.
I’d be shocked if the rotors are truly bad with this few miles on the car, but I’m new to this community, so I don’t really know. Apparently, according to CarMax, this issue is covered under their 30-day limited warranty, so I was planning on taking the car to their service department to have this issue fixed, but I don’t love the idea of having them do the work for fear of it not being done correctly / them damaging something.
What should I do? Will I likely need to buy new pads and rotors? Does this seem like something that should be fixed by proper burnishing?
