Recalls that may affect cars built around 2018

3 of the Mazda 6’s 29 recalls in DVSA’s records cover cars built during 2018. 3 have no build dates, so could apply to any year.

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.

4 Jan 2022 Low pressure fuel pump impeller might become deformed 6 Apr 2018 to 24 Oct 2018 26,974 (all models)

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.

  • MOT figures cover normal tests in Great Britain in 2025 of Mazda 6 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.
