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).

• !! Electric Water Pump Failure (Production Issue) from 30,000 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

• !! Recall: Ignition Coil Short Circuit (2015–2016 build year)

  Nissan Note and Renault Zoe/Kangoo with HR12 base engine received recalls for potential short circuits in the ignition coils on 2015–2016 build years. Affected vehicles should be checked for outstanding recall actions.

  Symptoms: Misfires; engine warning light; in the worst case engine stall while driving.

+ 2 more engine weaknesses + vehicle weaknesses

1.3-litre turbo developed with Daimler with significantly improved reliability compared to the 1.2 TCe. Direct injection promotes intake valve carbon build-up, ignition coils and spark plugs fail earlier than expected. Regular spark plug inspection from 60,000 km is advisable.

• !! Timing Chain Early Wear from 70,000 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 90,000 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

• !! Direct Injection: Intake Port Carbon Build-Up from 70,000 km

  As a direct injector without port injection, no fuel washes the intake valves. Carbon deposits on the intake manifold and valves are possible after 60,000–80,000 km.

  Symptoms: Power loss, rough engine running, increased fuel consumption
