J.D. Power and Associates has released its 2009 Initial Quality Study (IQS) and Lexus has taken the top spot away from Porsche, the initial quality leader for the past three years. The annual J.D. Power study measures IQS based on problems reported per 100 vehicles (PP100) -- a lower score means a lower rate of problem incidences and higher quality.
This year, the industry average is 108 PP100, demonstrating a steady improvement from 118 PP100 in 2008, and 125 PP100 in 2007. In addition to the marked improvement by the industry overall, many brands continued to perform well in 2009. Following Lexus and Porsche is Cadillac (which moves from 10th rank position in 2008 to third in 2009), Hyundai (jumping from 13th rank position in 2008 to 4th in 2009) and Honda (up from 7th in 2008 to 5th in 2009). Infiniti, second in last year's study, drops to 11th overall, while Suzuki posts the largest improvement in ranking, moving from 32nd place in 2008 to 9th in 2009. The complete J.D. Power press release and charts can be found after the jump and in the gallery below.
