Recalls that may affect cars built around 2018
2 of the BMW I3’s 9 recalls in DVSA’s records cover cars built during 2018.
The 2018 on this page is the year of first registration, not the year the car was built. A car first registered early in 2018 may have been built in 2017, and recalls apply to particular build dates and VINs, so check the recalls either side too.
| Launched | Concern | Built | Vehicles |
|---|---|---|---|
| 14 Nov 2022 | During supplier s production process of the battery cells a manufacturing defect occurred with the winding of cell-internal films for the high-voltage battery. | 12 Nov 2018 to 16 Jul 2021 | 18 |

| MOT results and mileage | Anonymised MOT tests and results Driver and Vehicle Standards Agency Derived statistics UK Motoring | 2025 | 3,106 MOT tests of 2018 BMW I3 cars | 15 September 2026 |

- MOT figures cover normal tests in Great Britain in 2025 of BMW I3 cars first registered in 2018; retests are excluded. “All cars” means every car we match to a model, first registered in 2018.
- 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.
