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.

Rover 50% pass rate 

Another ‘zombie’ firm in our bottom 10 manufacturers is Rover; however, unlike Daewoo, these results include a large volume of classic cars (like the P4, P5 and SD1) which probably explains why Rover outscores both Daewoo and Renault. VOSA recorded more than 200,000 Rover MoTs between 2012 -2013, with electrics and suspension being the two biggest causes of failure.
