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 7
Recall issued for vehicles produced between September and December 2015 due to possible fatigue fractures of the steering rod. Safety-critical.
Recall for 2012/2013 models due to faulty ignition unit wiring that could prevent airbag deployment in a crash.
Recall for several model years due to possible breakage of the bonnet latch bracket, which can cause the bonnet to fly open while driving.
Steering joints and tie rod ends remain regular weak points at MOT in the second generation as well. The defect rate is well above the vehicle average.
Lighting defects appear on the Logan II after just a few years of use. Low beam, tail lights, and indicators fail at well above average rates at MOT.
The Logan II's paint is thinly applied and vulnerable to stone chips. Windscreens scratch quickly and become hazy, impairing visibility in direct sunlight.
Battery failures are among the frequent breakdown reports for the Logan II, especially for model years 2012 to 2014. The standard batteries are undersized for the vehicle's power demands.
Reports & Tests
Defect rate of 39.6% on 10–11-year-old vehicles. Suspension, brakes, and exhaust emissions are chronic problem areas.
