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 1.5 K15B (Jimny) reliable?

The 1.5 K15B in the Suzuki Jimny is a 102 hp naturally aspirated four-cylinder with a timing chain, simple and with no documented faults of its own. The only thing recorded in Europe is a 2018-2020 recall for the fuel pump, precautionary and with a definitive remedy.[6][7][8]
