Anyone having clearcoat failure on their ML c-pillars?

[CarolinaMBZ]

Hi everyone. My mother's 2002 ML (Black) is having the clearcoat flake off of the plastic painted portions of the c-pillar on both sides of the liftgate. Garaged, purchased new with no adverse events. Is anyone else experiencing a similar problem and has anyone filed a claim with Mercedes on the issue? If so how did it pan out?

All info appreciated.
