Porsche was No. 1 in J.D. Power's Initial Quality Study in the United States for the second year in row, extending its lead over rivals compared with last year. Jaguar was No. 2, rising up from ninth place in 2013. Lexus rounded out the top three.
The 2014 Initial Quality Study is based on feedback from more than 86,000 buyers and lessees of new 2014 model year vehicles after 90 days of ownership. The study was conducted from February to May of this year.
Quality scores in the study are determined by the number of problems experienced per 100 vehicles, with lower scores signaling higher quality (see chart below).
Porsche had 74 problems per 100 vehicles, down from 80 problems in 2013. This year the difference between Porsche and its closest competitor was 13 problems while in 2013 it was 10 problems. Jaguar was second with 87 problems, a big improvement over last year when its cars had 104 problems per 100 cars.
Lexus was third for the second-straight year. The Toyota-owned luxury brand reduced its problems to 92 per 100 cars from 94 the year before.
Hyundai rose to fourth place from 10th last year by cutting its problems to 94 from 106. Toyota ranked fifth this year, up from No. 7 in 2013.
