Renault Scenic
Compact 1.4-litre 16-valve with solid fundamental construction; timing belt bends valves on failure, so replacement no later than every 60,000 km. Engine runs without notable weaknesses with correct care; camshaft adjuster should be inspected at the timing belt change.
Family Base
98 hp 1.4 16V in the Scenic — just adequate for the family van. No driving fun, but purpose served.
Engine Weaknesses 4
The K4J 1.4 16V is an interference engine; if the timing belt breaks, the valves bend. The risk increases significantly after long intervals or with aged tensioners. Change interval: no later than every 5 years / 120,000 km.
Symptoms: Sudden engine stop, no restart, compression loss in multiple cylinders
The Renault-typical Sagem ignition coils are also the most common cause of misfires and power loss in the K4J. Affordable aftermarket alternatives are recommended.
Symptoms: Misfire, cylinder dropout, engine warning light
The electronic throttle body on the K4J is prone to deposits from crankcase ventilation oil mist, causing idle fluctuations and occasional stalling.
Symptoms: Rough idle, engine stalls, power loss at low revs
At higher mileages K4J engines leak oil from the valve cover gasket and camshaft oil seals. Particularly common on vehicles above 150,000 km.
Symptoms: Oil traces on engine, oil smell, dropping oil level
Vehicle Weaknesses 8
Blocked water drainage channels lead to water ingress under the driver's seat. This damages the wiring harness and control units. Extensive repairs are the result.
Recall due to failure of the electric parking brake and problems with rear axle weld seams. Electric parking brake can require expensive replacement.
Defective window regulators, boot lid openers, wiper motors and radio systems are classics on the Scenic II. Instrument cluster unit fails; inexpensive repair available. Control units damaged by moisture.
Tie rod ends and suspension components are frequently flagged at vehicle inspections. Wheel bearings are also prone to failure and springs occasionally break.
The instrument cluster and speedo can fail completely, frequently due to solder joint defects on the circuit board. Reconditioning by specialists is possible; new parts are expensive and increasingly hard to find.
Rear brakes on the Scenic II wear quickly and require regular maintenance. Rear disc brakes are sensitive, especially when the brake is rarely used.
Seats squeak and the synthetic leather upholstery wears above-average quickly. Interior quality defects are a known issue with this generation.
The blower motor resistor fails frequently; the blower then only works on the highest setting or not at all. Replacing the resistor is an inexpensive repair but is often diagnosed late.
