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 7
Recall for vehicles produced between September and October 2016 due to possible detachment of brake caliper clips, which could cause the brake line to fracture.
Defective alternators have been reported on the Sandero II and can lead to sudden loss of electrical supply.
Faults in the steering column stalk of the light switch unit cause unreliable low beam operation. A known weak point that can result in MOT defects.
Suspension components, wishbones, and driveshafts show disproportionately high defect rates on the Sandero II from the second MOT. Tie rod ends and steering joints are regular weak points.
From the second MOT, brake discs show above-average wear. Braking performance on the brake tester frequently falls short.
The Sandero II shows early signs of corrosion on the underbody and sills after just a few years. Corrosion protection quality is well below the class average.
Battery failures are particularly common on early Sandero II model years. Disproportionately high breakdown reports, especially for the first years after market launch.
Reports & Tests
Defect rate of 8.2% on 2–3-year-old vehicles (average: 5.5%). Weak points: lighting, brake discs, exhaust emissions, and oil loss.
