The MoT Files: The 10 worst manufacturers

The bottom 10 manufacturers is one of the most important lists in the MoT Files, because it outlines the worst fail rates for all manufacturers for all years (1980-2013).

It’s important to bear in mind that there are a number of ‘zombie manufacturers’ in this list, with the cars continuing even though the companies have long since died. However, this note aside, the majority of firms in the bottom 10 are still very much alive and some of the results surround some of the UK’s most popular cars.

Renault 49% pass rate

Between 2012 – 2013 VOSA recorded 1,435,890 Renault MoT tests, yet just 49% of cars passed. Drill down into the failures and Renaults struggle with lamps, reflectors and electrics. Other common fail items include suspension and brake components.
