Is the 2.2 dCi and 3.0 dCi V6 reliable?

Renault's big 2000s diesels, the 2.2 dCi (G9T) and the 3.0 V6 dCi (P9X), have a poor reputation among owners: big-end bearing failures are cited on the 2.2 and overheating on the V6. The sources are mainly forums and the press that reports them, with no official statistics.[4][5][6]
