Recalls that may affect cars built around 2004
None of the Porsche Boxster’s 9 recalls in DVSA’s records has build dates that include 2004. 1 has 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.

Recall details come from manufacturers through DVSA. “Vehicles” is the number the manufacturer reported; “all models” means the figure covers everything in the recall. A recall listed here may not apply to a particular car: only the manufacturer or GOV.UK can say for its VIN.

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 | 1,994 MOT tests of 2004 Porsche Boxster cars | 15 September 2026 |

- MOT figures cover normal tests in Great Britain in 2025 of Porsche Boxster 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.
