Recalls that may affect cars built around 2012
4 of the Mercedes-Benz SLK-Class’s 25 recalls in DVSA’s records cover cars built during 2012. 1 has no build dates, so could apply to any year.
The 2012 on this page is the year of first registration, not the year the car was built. A car first registered early in 2012 may have been built in 2011, and recalls apply to particular build dates and VINs, so check the recalls either side too.

Data sources and methodology
| Figures | Source | Period | Records | Updated |
|---|---|---|---|---|
| MOT results and mileage | Anonymised MOT tests and results Driver and Vehicle Standards Agency Derived statistics UK Motoring | 2025 | 5,481 MOT tests of 2012 Mercedes-Benz SLK-Class cars | 15 September 2026 |
| Cars on the record | Vehicle licensing statistics Department for Transport | End of 2025 | 5,546 cars still on the record (licensed or SORN) | 15 September 2026 |
- MOT figures cover normal tests in Great Britain in 2025 of Mercedes-Benz SLK-Class cars first registered in 2012; retests are excluded. “All cars” means every car we match to a model, first registered in 2012.
- Year of first registration is DVSA’s first-use date: when the car was first registered, in the UK or abroad.
- Defects and advisories are DVSA’s descriptions made readable. Where on the car a defect was found (side, front or rear) is ignored, so the same fault on any wheel counts once per test.
- Mileage is the odometer reading at each car’s latest normal MOT of the year, as recorded by the tester. A few readings are in kilometres or mistyped; percentiles are not thrown by a handful of outliers.
- Cars on the record come from DfT table VEH0124 and cover the United Kingdom, including Northern Ireland; MOT figures cover Great Britain only.
- DVSA records the model name typed in at the test. We match those names to DVLA’s generic models, so a handful of tests may be counted under a close relative.
