Renault Austral 1

1.2-litre three-cylinder as the combustion component in the E-Tech hybrid system — naturally aspirated without turbo, which limits mechanical complexity. The multi-mode gearbox can occasionally transmit rough running; fuel economy benefits in urban driving are substantial (real-world under 5 l/100 km achievable).

• !! Recall: oil separator hose (engine damage risk)

  Factory recall 0EWA: a faulty oil separator hose lets fuel smell enter the cabin and the oil level rise. Ignored, it risks engine damage. Affected vehicles are repaired free of charge.

  Symptoms: Fuel smell in the cabin, rising oil level without a leak, engine warning

• !! Electric Water Pump Failure (Production Issue) from 25,000 km

  The electric water pump in the HR12-FHEV system on the Austral and Rafale E-Tech 200 failed systematically on early build years before June 2023. Coolant leaks from the heat exchanger and overheating risk. Renault officially acknowledged the problem and improved the pump.

  Symptoms: Overheating warning, coolant loss, 'check injection' message, possible engine damage

• !! Hybrid Gearbox: Judder and Shift Hesitation from 20,000 km

  The E-Tech hybrid gearbox on the Austral and Espace was criticised for unpredictable shift moments. A massive recall action affected 32,450 vehicles (production period October 2022 to June 2024) due to gearbox faults.

  Symptoms: Hard gear changes, hesitation on acceleration, gearbox fault message

+ 2 more engine weaknesses + vehicle weaknesses

A 1.3-litre turbo developed with Daimler, with a timing chain and clearly improved reliability over the 1.2 TCe. Weak points are the wastegate linkage of early years (before the mid-2020 factory revision), the leaking thermostat housing and the intake-valve coking typical of direct injection. Ignition coils and spark plugs fail earlier than expected — a check from 60,000 km is sensible. With good oil care a solid, everyday-capable engine.

• !! Timing Chain Early Wear from 120,000 km

  The H5H 1.3 TCe also shows initial timing chain rattling in 2019 models after 50,000–70,000 km. Chain tensioners in particular wear prematurely and must be replaced.

  Symptoms: Rattling on cold start, clattering on load changes, camshaft control fault code

• !! Wastegate Failure After 80,000+ km from 60,000 km

  The wastegate valve of the H5H 1.3 TCe turbocharger wears after 80,000–100,000 km, causing power loss and increased oil consumption.

  Symptoms: Power loss, no boost build-up, whistling from the turbo area

• !! Thermostat housing leak from 70,000 km

  The thermostat housing and its seals start to leak and coolant is lost without a visible external leak. Ignored, it risks overheating. The fault pattern and the part are known from the identical Mercedes engine.
