Historical MOT pass rates and DVLA records for 1999 model year cars.
- Blocked Plenum DrainsSerious
Leaves and debris block the drains, leading to water entering the cabin and damaging the CCM.
- Front Multi-Link Suspension WearModerate
The C5 uses a sophisticated aluminium multi-link front suspension with eight control arms per side. Bushings harden and ball joints develop play, causing clunks and vague steering.
- Instrument Cluster Pixel FailureModerate
The dot-matrix LCD in the instrument cluster loses pixels column by column, making the trip computer, odometer and warnings unreadable.
