Is the Mitsubishi PHEV reliable?

Yes, with caveats: the OCU ranks the Outlander PHEV first for reliability among used plug-in hybrids. What is documented are isolated campaigns (spark plugs and software, air flow sensor, fuel hose) and a possible loss of battery capacity, cited by one source and one study without figures. The Eclipse Cross PHEV, which uses the same system, has no documented faults of its own.^{[1][2][3][4][5]}

Is the 2.0 FSI reliable?

The 2.0 FSI is the naturally aspirated version with which the Volkswagen Group introduced petrol direct injection in a two-litre engine, before moving on to the turbocharged 2.0 TSI. Two faults recur across several models: carbon build-up on the intake valves, inherent to direct injection, and ignition coil failure, documented from 5,000 km in one case. Gebrauchtwagenberater.de nevertheless counts it among the most reliable petrol engines in the Audi A4 B7.^[6][7][8][9]
