Renault Scenic
Turbocharged four-cylinder with a well-known timing chain weakness: chain elongation can lead to engine damage from as early as 75,000–150,000 km, including connecting rod bearing failures. Pre-purchase inspection and complete service history are absolutely mandatory.
Naturally Aspirated Alternative
131 hp 1.4 TCe — without the timing chain problems of the 1.2 TCe. The safer choice.
Engine Weaknesses 5
The Clio V received recalls for its electric power steering during the production period April–October 2019. H4J-engined variants are also affected.
Symptoms: Power steering failure while driving, heavy steering
In the H4J700 the timing chain stretches from around 130,000 km, noticeable as rattling on cold start. The hydraulic chain tensioner needs more travel once the chain has stretched — repair costs around €3,000.
Symptoms: Knocking/rattling noise from the timing chain area on cold start, lasting 3–4 minutes and subsiding after warm-up.
Known issue on the H4J: cracks in the cylinder head allow coolant to enter the combustion chambers. Identifiable by a falling coolant level without any visible external leak. Typical after 80,000–120,000 km.
Symptoms: Coolant level drops regularly without visible leak; white smoke from exhaust; mayonnaise deposits on oil filler cap.
The H4J 1.0 TCe 90 in the Clio V shows similar wastegate mechanism wear to the H4B. Still not well-documented as a young engine, but confirmed from forum experience.
Symptoms: Power loss, whistling noises, no boost pressure build-up
Small turbocharged three-cylinder engines are inherently prone to increased oil consumption by design. Regular oil level checks and shortened change intervals are recommended.
Symptoms: Dropping oil level, occasional blue smoke
Vehicle Weaknesses 7
Blocked bodywork drainage channels let water into the interior and damage the wiring harness under the driver's seat. Numerous electrical failures result. Regular inspection of drains recommended.
A defective relay 1155 in the left A-pillar disables the power supply of several control units. Power steering, air conditioning, radio, navigation and boot release can all fail simultaneously.
Springs, dampers and steering joints fail above-average on the Scenic III at vehicle inspections. Typical suspension problem that occurs in the mid-mileage range.
Brake components on the Scenic III wear significantly faster after about 7 years. MOT data confirm significantly higher defect rates with age. Rear brake calipers tend to seize.
After about 5 years, underbody corrosion increases on the Scenic III. Brake lines and the exhaust are preferred rust spots. Regular underbody inspection is recommended.
The chrome strip on the tailgate rubs through the zinc coating and causes rust underneath. Renault has been aware of the defect since 2011 but hasn't resolved it structurally. Repairs often only last around one year.
Rear window regulators fail. Lighting fails regularly within 4 years. Typical electronics problems of the range with moisture as a frequent cause.
Reports & Tests
Failed springs and dampers are a recurring weakness. Steering joints are regularly flagged. Front lighting is too often defective; older vehicles show increased brake disc wear.
