Is the 1.4 T-Jet reliable?

Fiat's 1.4 T-Jet/MultiAir powers a large part of the group's turbo petrol range (Fiat, Abarth, Alfa Romeo, Lancia, Jeep) from 2007 onwards. Several models have accumulated reports of turbocharger failure, MultiAir/UniAir unit faults and high oil consumption; by contrast, there is no documented pattern of timing belt failure.[1][2][3][4][5][6]

Is the 2.0 and 2.2 16v EW10/EW12 reliable?

The EW10 (2.0) and EW12 (2.2) are naturally aspirated 16-valve petrol engines with a timing belt, which PSA fitted between 1999 and 2010 to the 206, 307, 406, 407, 607, 807, C4, C5 and C8, among others. According to owners there are no frequent internal failures: the most-cited problems are the ignition coils (the only fault also reported by the press), the exhaust and, on the 2.2, oil consumption.[7][8][9][10][11][12][13][14]
