Historical MOT pass rates and DVLA records for 2009 model year cars.
- CVT gearbox failureSerious
The CVT transmission can suffer from worn variators, overheating and mechatronic unit failures. Jerky acceleration and whining noises are common. Regular fluid changes are critical to延 life.
- DPF blockage (diesel models)Moderate
The diesel particulate filter clogs quickly on short urban journeys, triggering limp mode. Regular motorway driving is needed for passive regeneration.
- Seat belt webbing frayingModerate
The seat belt webbing on B-Class models is prone to premature fraying at the edges, which is an MOT failure. Replacement belts are surprisingly expensive.
