Dacia Logan
Structurally simple, robust 1.6-litre naturally aspirated engine with high mileage potential. The water pump is the weak point: if it fails, the engine overheats and head gasket damage threatens. Camshaft bearings can become noisier at higher mileages.
Solid everyday engine
The 1.6 with 84 hp is adequate in the Logan. No fire in the belly, but reliable and frugal.
Engine Weaknesses 4
Timing belt due every 60,000–90,000 km. Not interference-free — a snapped belt means valve damage and total engine failure.
Symptoms: Timing belt due every 60,000–90,000 km
Trigger wheel shifts due to crankshaft axial play. TDC sensor loses signal; engine fails to start or runs rough.
Symptoms: Trigger wheel shifts due to crankshaft axial play
Same weakness as the K7J — valve fouls, engine stalls at idle. Cleaning usually helps.
Symptoms: Same weakness as the K7J — valve fouls, engine stalls at idle
Valve cover gasket becomes porous after 100,000+ km. Oil loss visible at the cylinder head. Inexpensive to replace.
Symptoms: Valve cover gasket becomes porous after 100,000 km
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.
