I've always found JD Power to be a bit biased towards American made cars. Maybe because he worked for Ford and GM, I don't know, but even at their worst, they always seemed to be featured by them.

I'm not sure about the American bias, as I see tons of non-US cars in the sedans list, but their truck ratings are a travesty:

I have been utterly unimpressed with the Silverados and Avalanches. For that kind of money, I expect a lot more than fragile/cheap interiors (Silverado) and the crummy bed on the Avalanche.
