Porsche claimed the top ranking in J.D. Power and Associates' 2010 Vehicle Dependability Study, with Lincoln, Buick, Lexus and Mercury rounding out the top five.
Buick fell from the top spot in the 2009 study (as did Jaguar and Lexus, which were ranked second and third in 2009, respectively), while Porsche came from 10th place to take the top honor. Ford had a particularly good showing, with all three of its brands in the top 10.
Toyota, Honda and Ford were the top three non-luxury nameplates on the list, respectively.
Perhaps the biggest story, according to J.D. Power, is the gap between a brand’s dependability — as measured by problems per 100 vehicles — and consumer perception. Cadillac, Ford, Hyundai, Lincoln and Mercury all have decent reliability ratings that are not reflected by consumers' opinions about those brands. This makes for an unfortunate predicament when you’re trying to sell cars.
The Vehicle Dependability Study works by counting problems experienced by original owners of 3-year-old vehicles (from the 2007 model year). For the 2010 study, 52,000 vehicle owners were surveyed between October and December of 2009.
