US car in top 5 reliability in a long time, it wasn't Ram

Considering how political polls have been working, I'm not sure how to take these surveys even though I don't dispute their data. My 2011 Ram has been excellent but it has less than 45,000 miles on it, mostly towing a 5th wheel. I received a JD Power survey for my 2013 Audi Q5 which has over 30,000 miles so far and has been flawless. I didn't fill it out however and I wonder how many others receive these things and don't bother with them.
