Brake pad worn unevenly and diagonally

Hi all,

Have a 2016.5 90D with the mando rear calipers. Rotors were warped and went to the service center for replacement. They replaced the rotors and pads but with the way the old pads were worn, I would have expected them to do more diagnostics.

The drivers side rear is worn more than the passenger side rear and looks like it wore down at an angle. The drivers side is on the left in the pic.

Any ideas what could cause this? Any input would be appreciated.

Most Tesla brakes don't get very much use due to regenerative braking. It's common for the sliding surfaces of the pads to get corroded, so when the pads are up against the rotors they don't always retract. Sometimes the calipers get stuck because of contamination buildup inside the piston.
