Dacia Sandero
Renault's 1.6-litre 16V naturally aspirated engine is one of the most robust in the Renault family — mileages above 300,000 km are well documented. The variable valve timing (VVT) unit can cause rattling noises and slight power loss on a warm engine. Engine mounts wear and lead to noticeable vibrations at idle.
Refined four-cylinder
The 1.6 16V with 105 hp brings a bit more character to the Sandero. Revs cleanly and feels livelier than the 8V engines.
Engine Weaknesses 4
Timing belt and water pump due every 120,000 km or 6 years. More involved replacement than on the K7M due to the 16V head.
Symptoms: Timing belt and water pump due every 120,000 km
VVT oil control valve fouls and sticks. Rattling on cold start; power loss. Clean or replace the solenoid valve.
Symptoms: VVT oil control valve fouls and sticks
Ignition coil housing develops hairline cracks; moisture ingresses. Engine runs on 3 cylinders; misfires in wet conditions.
Symptoms: Ignition coil housing develops hairline cracks; moisture ingresses
Throttle body fouls with blow-by gases. Rough idle and hesitation when pulling away. Regular cleaning recommended.
Symptoms: Throttle body fouls with blow-by gases
Vehicle Weaknesses 8
Recall for vehicles with the 1.2L engine produced between September and November 2010 due to faulty valve cotters in the cylinder head, which could lead to catastrophic engine failure.
Steering joints and tie rod ends are among the most frequent MOT defects on the Sandero I. The defect rate is well above average for comparable vehicle classes.
Early Sandero I models frequently had ignition coil failures. Ignition leads also showed faults in the early years of service. Primarily affects model years 2008 and 2009.
From model year 2010, starter motor failures were frequently reported on the Sandero I. Weak batteries and faulty ignition switches compound the starting problem.
The Sandero I's exhaust system rusts through comparatively early. A complete exhaust replacement can be necessary after just 3–5 years.
Ball joints and wishbones wear faster than average on the Sandero I. Suspension components show elevated defect rates as early as the first and second MOT.
The fuel filler neck is known for early corrosion, which can lead to fuel leaks.
The Sandero I's standard batteries are marginal for the vehicle's power demands. Premature discharge and failures after just 3–4 years are a well-known breakdown pattern.
