1.2 TCe vs M50 and M52: which engine is more reliable?
According to our risk index, the M50 and M52 carries less risk than the 1.2 TCe: 52/100 versus 54/100 (both high risk). The 1.2 TCe has 2 documented serious faults, the main one being «Excessive oil consumption and engine failure»; the M50 and M52 has 2 documented serious faults, the main one being «Cooling system failure (expansion tank, thermostat, pump and radiator)».
The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the 1.2 TCe reliable?
Only with reservations: 1.2 TCe and 1.2 DIG-T engines built between 2012 and mid-2016 can burn a lot of oil because of poor piston ring sealing, with a risk of damaging the valves, stretching the chain or destroying the engine. Renault and Nissan dealt with it through technical notes and case-by-case assistance, without a recall; later production incorporates the fix.[1][2][3][4][5]
See the 2 of the 1.2 TCe faultsIs the M50 and M52 reliable?
The M52 and its predecessor the M50 are six-cylinder petrol engines that the sources describe as durable: Enginescope considers 300,000 km routine with the cooling circuit looked after. Watch the plastic cooling parts, VANOS, crankcase ventilation and oil leaks and, in the aluminium-block M52s built from 1995 to March 1998, cylinder wear caused by sulphur (Nikasil).[6][7][8]
