GLC300 Cracked Piston

[GLC300 Owner]

Have a 2017 GLC300 with 23K miles with a 4 year/50K warranty that expired ~6 months ago. Diagnosis is Cylinder 2 Piston Cracked. Received a quote from dealer $5300. Reading other posts, this may be a known issue with MB. Looking for feedback on other experiences, this is completely nauseating. I have a case opened with MB corporate to cover the costs. Any input is appreciated.

There was a similar post not so long ago with a C class AMG, again US manufactured. Doesnt seem to be an issue this side of the pond. US corp may and likely will say, nit thier problem as its opens liability for them. US law vis a vis UK law, different strokes for different folks
