Recalls that may affect cars built around 2021
1 of the BMW 1 Series’s 39 recalls in DVSA’s records covers cars built during 2021. 2 have no build dates, so could apply to any year.
The 2021 on this page is the year of first registration, not the year the car was built. A car first registered early in 2021 may have been built in 2020, and recalls apply to particular build dates and VINs, so check the recalls either side too.
| Launched | Concern | Built | Vehicles |
|---|---|---|---|
| 29 Dec 2021 | The material quality of the screws used for seat belts and rear seats may not be to specifications. | 22 Oct 2021 to 27 Oct 2021 | 38 (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 | 14,643 MOT tests of 2021 BMW 1 Series cars | 15 September 2026 |
| Cars on the record | Vehicle licensing statistics Department for Transport | End of 2025 | 15,069 cars still on the record (licensed or SORN) | 15 September 2026 |
- MOT figures cover normal tests in Great Britain in 2025 of BMW 1 Series cars first registered in 2021; retests are excluded. “All cars” means every car we match to a model, first registered in 2021.
- 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.
