Do you have any details on what Warrentywise uses for their data? The data seems to suggest all of the "cheap" cars are more reliable then all of the "expensive" cars. Which is just wrong, if anything it's a spread of cheap/expensive on top and cheap/expensive on bottom.

That data seems to imply there is perhaps another reason for the rankings then what is to be assumed.

They do include the cost to repair among other things, which means that only do they break often, they also cost a lot to fix. Cheap brands on the other hand when they do break down are either fixed by the manufacturer for free or dont break as often. German cars are infamous for the high number of defects that their manufacturers wont issue recalls for. Therefore the ranking is accurate.

It still feels a bit off. I expect an expensive car to have expensive repairs. When looking at the cost of a repair I would perhaps consider the cost as a proportion of the MSRP, or resale value, not the raw cost.

Warrantywise does aftermarket extended warranties in the UK.

I can't say how but it seems to me that may have an influence on their data.
