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 87 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. Non-interference engine — but a snapped belt means valve damage and a write-off.
Symptoms: Timing belt due every 60,000–90,000 km
Trigger wheel shifts due to crankshaft axial play. TDC sensor loses signal, engine won't start or runs roughly.
Symptoms: Trigger wheel shifts due to crankshaft axial play
Same weakness as the K7J — valve gets fouled, engine stalls at idle. Cleaning usually fixes it.
Symptoms: Same weakness as the K7J — valve gets fouled, engine stalls at idle
Valve cover gasket becomes brittle after 100,000+ km. Oil loss visible at the cylinder head. Cheap to replace.

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.
