Historical MOT pass rates and DVLA records for 2004 model year cars.
- M272 V6 Balance Shaft WearSerious
Early 3.0L and 3.5L V6 engines used soft metal gears on the balance shaft. The gears wear down, altering engine timing and requiring a massive engine-out repair.
- Vario-Roof Hydraulic LeaksModerate
The complex folding hardtop uses multiple hydraulic cylinders that can leak as the seals age.
- Rear Subframe Corrosion and PerforationSerious
The pressed-steel multi-link rear subframe on the R171 SLK is highly prone to severe internal corrosion, aggravated by decades of wet UK winter roads and road salt. Moisture and grime accumulate inside the hollow box sections, rusting the subframe from the inside out until structural perforation occurs around the suspension control arm mounting points. In severe cases, an arm mount shears off entirely, causing sudden dangerous rear-wheel steering and an immediate MOT failure. Mercedes-Benz UK has historically assessed replacements under goodwill on a case-by-case basis.
