Is the M112 / M113 reliable?

The M112 (V6, 2.4 to 3.7 litres) and the M113 (V8, 4.3 to 5.5 litres) are Mercedes-Benz petrol engines from 1997 to 2011 (the V6 ends earlier, around 2006). The sources treat them as reliable if maintained: the documented faults are mainly oil leaks from the covers, the crankshaft sensor and, on some units, the crankshaft pulley.^[1][2][3]

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.^[4][5][6]
