If you want to compare on a corporate level, you could take the average of their brands scores (relatively simple). Or, if you wanted a fairly accurate picture you could look up what each brand sold from August 2011 through July 2012 (approximately the 2012 model year that JD power is looking at) and use that data to do a volume-weighted average. Multiply the brands reliability by its sales volume then add up all of a companies brands & divide by companies total volume. That should give a pretty clear picture as to which company has the most reliable cars & trucks. It won't be perfect, but its a lot more meaningful than counting how many brands it has in the top 10. If you did all that, GM would probably be 4th behind Toyota, Honda, and Mercedes-Benz but ahead of 9(?) other companies.

I agree that your weighting scheme would paint a much clearer picture. Still, the contrast between GM and Fiat (who have so many brands) on these list is striking. Polar opposites
