NPR posted a nice widget on their web site, here, where you can check the statistics on unintended acceleration complaints. Most importantly, the data is normalized, so you can see which carmakers are having more complaints than their market share and which are getting less.
Here is a snapshot for 2009. Notice that the worst three carmakers, in terms of complaints per 100,000 vehicles, are Toytoa, VW, and BMW. Also notice that VW/Audi is more over-represented even than Toyota is!
