Mitsubishi PHEV vs 1.0 TCe / SCe: which engine is more reliable?

According to our risk index, the Mitsubishi PHEV carries less risk than the 1.0 TCe / SCe: 24/100 (low risk) versus 41/100 (moderate risk). The Mitsubishi PHEV has 2 documented serious faults, the main one being «Corroded air flow sensor: the petrol engine does not start to charge the battery»; the 1.0 TCe / SCe has 1 documented serious fault, the main one being «LPG (ECO-G) system faults and tank recall».

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 1.0 TCe / SCe reliable?

The 1.0 TCe/SCe (H4D/H4Dt) is a simply designed three-cylinder with reasonable reliability. Its most-cited fault is a noise or vibration from the turbo wastegate; the ECO-G (LPG) version adds its own gas-management faults and a 2023 recall over a risk of leaks and fire from the tank. An isolated case of a failed high-pressure pump is also documented, and no oil consumption pattern.[6][7][8]
