Dacia Logan
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 Logan. 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
Due to poor paint quality and inadequate corrosion protection, rust forms early on sills, wheel arches, and underbody. Vehicles in salt regions are particularly badly affected.
Recall for affected models due to rust on the rear shock absorber mounts. Structural weakening can compromise driving safety.
Steering and steering joints are among the most frequent MOT complaints. The defect rate is well above average for comparable vehicles.
Brake discs and pads wear faster than average on the Logan I. Regular MOT complaints, braking performance frequently insufficient.
The Logan I's exhaust system is known for early corrosion. A full replacement can be needed after just a few years and regularly causes MOT failures.
The Logan I's low beam shows far above average defect rates at MOT. According to inspection reports, front lighting is up to three times worse than average.
Recall for unreliable ABS warning light failures. The warning light malfunction can delay detection of ABS defects.
The Logan I's interior suffered from cheap plastics and poor panel gaps from the start. Over time, pronounced rattling develops from the dashboard and door panels.
