Many Mercedes manufacturing faults first come to light as subjects of class actions from owners in the USA. If a particular Mercedes model is not imported to the US then such faults are less liable to receive global/European publicity. Don't think the GLC is imported to the states but may be wrong there. As BlackC55 says rear subframe failure on the GLC is not commonly found unless its been subject to extremely corrosive conditions. Sounds a bit like a get out of contract loophole the dealer has used but who knows? The GLC is often assembled by Valmet in Finland
