The German sports car manufacturer ended the luxury Japanese marque's two-year reign at the top of the US automotive industry analyst's study, while General Motors' GMC division soared into second position, bumping Lexus to third.
A strong year for GM saw a second of its brands, Chevrolet, rank inside the top five, while eight vehicles from its Buick, Chevrolet, GMC and Cadillac divisions shared seven of the 23 individual segment awards up for grabs.
The JD Power Initial Quality Study is based on responses from more than 83,000 owners and lessees of 2013 model year vehicles surveyed after 90 days of ownership. The results of the 233-question survey are compiled to produce a score for each vehicle measured as problems per 100 vehicles (PP100).
Porsche’s 80 PP100 rating made it the standout in this year’s study. Asian manufacturers performed strongly, filling seven of the top 11 positions, with Japanese brands taking out five of the top eight.
Six American brands finished on or above the industry average of 113 PP100, while four ranked below the black line. Ford was among the most disappointing, ranking seventh from the bottom with 131 PP100.
The Lexus LS was the highest-quality vehicle according to the survey, recording a score of just 59 PP100.th
The study found that many of the problems owners have with their vehicles relate to the driver interface, which includes voice recognition or hands-free technology, Bluetooth pairing for mobile phones, and navigation systems, among others.
