Top issues to watch for

The most serious Dacia Logan problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Suspension component detachment risk
MCV1, MCV22004–202140k–100k miles
Suspension pins, bushes, and joints on the 1.5 diesel variants show extremely high failure rates, with MOT data showing up to 50 times the national average failure rate at 40-60k miles. These components can become detached without warning, causing complete loss of vehicle control. The issue affects multiple suspension components including control arm bushes and ball joints, with the problem worsening over time according to MOT trend data.
What happens if ignoredComplete component failure can cause sudden loss of vehicle control, particularly dangerous during cornering or braking. Repair typically requires replacement of multiple suspension components simultaneously. The car should not be driven if any suspension component shows signs of imminent failure.

Major
Suspension component fracture (MCV2)
MCV22012–202180k–150k miles
The 0.9 petrol engine variants show suspension component fractures at 27.5 times the fleet average at 80-100k miles. This affects structural suspension components that can crack or break under load, particularly on higher mileage examples. The issue is distinct from bush wear and involves actual metal component failure.
What happens if ignoredFractured suspension components can fail completely, causing loss of vehicle control. Repair requires replacement of the affected structural component and thorough inspection of related parts. Continued driving with cracked components risks sudden failure.

Excessive suspension bush wear
MCV1, MCV22004–202120k–120k miles
All engine variants show suspension bush wear at up to 13.6 times the fleet average, with some failures occurring as early as 20-40k miles on the 1.1 petrol. This affects the rubber bushes in control arms, anti-roll bar links, and other suspension joints. The issue appears across all variants but is most pronounced on the 1.1 petrol engine cars.
What happens if ignoredWorn bushes cause poor handling, increased tyre wear, and transmission of road noise and vibration into the cabin. While not immediately dangerous, severely worn bushes can affect braking stability and should be replaced promptly.

The 1.0 petrol and 1.5 diesel engines show malfunction indicator lamp (MIL) failures at up to This typically indicates emissions system faults, sensor failures, or engine management issues that trigger the warning light. The problem affects both petrol and diesel variants from relatively low mileage.
What happens if ignoredWhile the car will usually remain driveable, an illuminated management light indicates a fault that can affect emissions compliance, fuel economy, and may lead to more serious engine damage if ignored. Diagnosis and repair of the underlying cause is required.
