Recalls that may affect cars built around 2015
1 of the Smart Forfour’s 5 recalls in DVSA’s records covers cars built during 2015. 1 has no build dates, so could apply to any year.
The 2015 on this page is the year of first registration, not the year the car was built. A car first registered early in 2015 may have been built in 2014, and recalls apply to particular build dates and VINs, so check the recalls either side too.
| Launched | Concern | Built | Vehicles |
|---|---|---|---|
| 25 Sept 2017 | Handbrake may not hold | 1 Apr 2014 to 31 Jan 2016 | 9,181 (all models) |

- MOT figures cover normal tests in Great Britain in 2025 of Smart Forfour cars first registered in 2015; retests are excluded. “All cars” means every car we match to a model, first registered in 2015.
- 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.
