1.0 TCe / SCe vs 1.2 16v: which engine is more reliable?

According to our risk index, the 1.2 16v carries less risk than the 1.0 TCe / SCe: 36/100 versus 41/100 (both moderate risk). The 1.0 TCe / SCe has 1 documented serious fault, the main one being «LPG (ECO-G) system faults and tank recall»; the 1.2 16v has 1 documented serious fault, the main one being «Damaged head gasket and coolant loss».

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.^[1][2][3]

Is the 1.2 16v reliable?

The 1.2 16v (D4F) and its 8-valve predecessor, the D7F, are simple naturally aspirated engines, used for over two decades as the entry-level option in Renault and Dacia cars, with a reputation for reliability: the reliability pages consulted document no catastrophic failures and no oil consumption. The most-cited problems are ignition coils and sensors and, on higher-mileage cars, the head gasket.^[4][5][6][7]
