This is just ignorance. JDP's data is much more superficial than CR's, their sample size is smaller, and they only survey 3 year old cars versus up to 8 for CR. You can criticize CR legitimately for certain shortcomings, but you shouldn't claim JDP results are better. Oh and BTW JDP has long shown Toyota and Honda at the top, just like CR.
By far the best reliability numbers are kept by the automakers themselves. Ford, GM, and Toyota know exactly how many problems their cars have because they are reported back through dealers. Too bad these numbers are closely guarded trade secrets. Once in a while, though, you can tell when the internal numbers agree/disagree with CR surveys. When CR's survey gave a black dot to the 2004 F-150, Ford came out and said their internal data showed otherwise. On the other hand, when CR's survey gave a black dot to the 2005 Chevy Cobalt, GM basically said that next year's model would be better, suggesting CR's survey was on to something.
