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 E-Tech Híbrido reliable?

The E-Tech combines a combustion engine (1.6 H4M naturally aspirated or 1.2 HR12 turbo) with electric motors and a multi-mode gearbox with no clutch or torque converter. Its best-documented weak point is the gearbox itself: reports from the Clio, Captur, Arkana, Austral, Duster and Jogger describe warnings of a risk of breakage, and Renault has launched two campaigns since 2020 (an electrical fault and a primary shaft seal). The 12 V battery also fails fairly often.^[6][7][8]
