View full entryCard, pressure sensors, front suspension, turbo and clutch on the Laguna IIKnown weak points
- Engine / equipment
- Renault Laguna II (petrol and dCi)
- Period mentioned
- 2001–2007
- Symptoms
- The car will not open or start (card, reader or start button); false tyre-pressure warnings; front-axle play; on diesels, turbo failure; a clutch that wears out before 50,000 km; rust on load-bearing parts.
- Possible cause described
- The hands-free card is its biggest weak point. Front-axle parts (links, ball joints, arms and bushes) are under-engineered. Auto Bild mentions an undersized clutch that may need replacing before 50,000 km (about €950).

View full entryOil leaks, clutch and water pump on the first-generation MéganeKnown weak points
- Engine / equipment
- Renault Mégane I and Scénic I (petrol and diesel)
- Period mentioned
- 1996–2003
- Symptoms
- Engine or gearbox oil leaks, a clutch worn out before 100,000 km, leaking shock absorbers, a leaking water pump and a rusty exhaust; light and rear-brake faults.
- Possible cause described

- Engine / equipment
- E-Tech hybrid and plug-in: Clio, Captur, Mégane and Arkana
- Period mentioned
- 2020–2023
- Symptoms
- “Stop” warning with the message “electrical fault, danger”, loss of drive and the car stranded.
- Possible cause described
- The “Onduflex” washer linking the main electric motor to the dog-clutch gearbox (which has no clutch) can break. Renault preventively reprogrammed over 150,000 cars in France built between 29/4/2020 and 13/4/2023.
- Check for the garage
- Ask Renault by VIN whether the reprogramming was done; with the warning, stop somewhere safe.

View full entryBrakes, damp-sensitive ignition and crankshaft seal on the first-generation TwingoKnown weak points
- Engine / equipment
- Renault Twingo I (1.2 and 1.2 16V)
- Period mentioned
- Approx. 1997–2007
- Symptoms
- Badly worn brake discs and cracked brake hoses; misfires or hard starting in damp weather; oil leaking between engine and gearbox; play in the front axle; failing rear lights.
- Possible cause described
- The TÜV report published by AUTO BILD criticises the brakes above average (discs and hoses on five- and seven-year-old cars). The ignition reacts to damp, especially the distributor cap; oil loss usually comes from the crankshaft seal behind the flywheel; the front axle wears. The new four-cylinder engine from 1997 is more reliable than the earlier one.
- Check for the garage
- Measure the discs and check the brake hoses; dry and check the ignition if it misfires in the rain; look for oil between engine and gearbox; check front-axle play and the lights before the roadworthiness test.

View full entryGear-selector actuator on the E-Tech 200 hybrid gearboxGearbox
- Engine / equipment
- E-Tech full hybrid 200 (1.2 turbo three-cylinder with clutchless dog gearbox): Renault Austral, Espace and Rafale
- Period mentioned
- 2022 onwards
- Symptoms
- Gearbox fault warning on the dashboard and limited performance; somewhat abrupt or slow shifts, typical of an unsynchronised gearbox.
- Possible cause described
- Renault recalled the Austral E-Tech full hybrid (campaign 0E8K, letter of January 2024) for a possible gearbox fault: it replaces the selector actuator free of charge. The dog gearbox has no synchronisers, which is why each shift takes about half a second.
- Check for the garage
- Check campaign 0E8K by VIN in the MyRenault app or at the dealer; if the warning appears, ask for the gearbox codes to be read.

View full entryCoolant leak over a battery connector and charging failures on the Scénic E-TechHigh-voltage battery
- Engine / equipment
- Renault Scénic E-Tech Electric
- Period mentioned
- 2024–2025
- Symptoms
- The battery will not charge or the car loses power; “electrical check required” warnings; low coolant level; on fast chargers, the session sticks at “communication pending”.
- Possible cause described
- In Renault’s official E-Tech community, owners report that in April 2025 they received campaign 0EKN in the MyRenault app or by letter, for possible contact oxidation that can stop charging or cause power loss: a coolant pipe above a traction battery connector can leak. The garage dismantles to inspect and replaces the pipe; there were waits for parts. One owner had both the 12 V and the traction battery replaced after the warning, and in the common-problems thread others mention fast-charging communication failures fixed by reprogramming the battery management.
- Check for the garage
- Check campaign 0EKN by VIN at a Renault dealer or in the MyRenault app; keep an eye on the coolant level.

View full entryA 12 V battery that drains and leaves the Symbioz unable to unlock or startElectrical and electronic systems
- Engine / equipment
- Renault Symbioz E-Tech full hybrid
- Period mentioned
- 2024–2026
- Symptoms
- After one or two nights standing, the car will not unlock with the card or start; in other cases, a breakdown that immobilises the car with several warning lights on.
- Possible cause described
- In Renault’s official E-Tech community, several Symbioz 145 owners report 12 V batteries going flat overnight on low-mileage cars: one had it replaced after the second breakdown and three weeks at the garage, another the day after delivery and another under warranty after insisting. Renault has not published the cause; short trips and leaving the car awake (phone connected, lights) make the drain worse. Another thread describes a Symbioz immobilised with several warning lights that the dealer could not diagnose.
- Check for the garage
- Ask for a load test of the 12 V battery and a check for software updates; if it keeps going flat, claim it under warranty.
