Recalls that may affect cars built around 2004
3 of the Mercedes-Benz A-Class’s 92 recalls in DVSA’s records cover cars built during 2004. 3 have no build dates, so could apply to any year.
The 2004 on this page is the year of first registration, not the year the car was built. A car first registered early in 2004 may have been built in 2003, and recalls apply to particular build dates and VINs, so check the recalls either side too.

|---|---|---|---|
| 17 Aug 2021 | The driver's air bag may have a chemical change to its propellant over time | 30 Aug 2004 to 4 Dec 2013 | 61 (all models) |

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 | 904 MOT tests of 2004 Mercedes-Benz A-Class cars | 15 September 2026 |

- MOT figures cover normal tests in Great Britain in 2025 of Mercedes-Benz A-Class cars first registered in 2004; retests are excluded. “All cars” means every car we match to a model, first registered in 2004.
- 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.
