Data at the type level is problematic too. For instance, CR also has data showing that Hybrids are the most reliable but PHEV's are the worst. Which doesn't make any sense because they are very similar vehicles, and PHEV's should theoretically be better than non-pluggable hybrids. But most Hybrids are Toyotas, and most PHEV's aren't.
