Recalls that may affect cars built around 2015
3 of the Kia Optima’s 6 recalls in DVSA’s records cover cars built during 2015.
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 |
|---|---|---|---|
| 5 Dec 2024 | Kia HECU Fuse Replacement | 9 Feb 2010 to 23 Jul 2015 | 3,069 |
| 13 Nov 2023 | Certain engines may have been produced with conditions that can cause premature wear of the connecting rod bearings | 4 Dec 2015 to 13 Sept 2018 | 610 |

|---|---|---|---|---|
| MOT results and mileage | Anonymised MOT tests and results Driver and Vehicle Standards Agency Derived statistics UK Motoring | 2025 | 583 MOT tests of 2015 Kia Optima cars | 15 September 2026 |

- MOT figures cover normal tests in Great Britain in 2025 of Kia Optima 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.
