Porsche retains J.D. Power’s top quality title

All-new vehicles have most problems

Porsche ranked highest in initial quality for the second consecutive year, followed by Jaguar and Lexus.

NEW YORK — The 2014 J.D. Power Initial Quality Study found that new vehicle owners experienced more problems with their vehicles than the previous year’s respondents, the company said Wednesday.

Porsche ranked highest in initial quality for the second consecutive year, followed by Jaguar and Lexus. Fiat came in last, followed by Jeep, another Fiat-Chrysler product.

The study, in its 28th year, measures the number of problems new vehicle owners experience during the first 90 days of ownership. The study, which looked at 207 models from 2014, measures the number of problems experienced per 100 vehicles. A lower score reflects higher quality.

The industry average for initial quality was 116 problems per 100 vehicles, up from 113 in 2013, a 3 percent increase.

“It’s a measurable change, but not a dramatic increase,” David Sargent, vice president of global automotive at J.D. Power, said in a telephone interview. “It’s a blip, we think, and it’s driven largely by two things.”

First, vehicles that are all-new or that have undergone major redesigns continue to have more problems than those that carry over without significant changes. On average, all-new vehicles or major redesigns had 128 problems per 100 vehicles; vehicles without significant changes had 113. And, among the all-new vehicles, the increase in problems was mainly, once again, in the areas of voice recognition, Bluetooth pairing and audio systems. Consumers continue to report that this new technology is hard to understand, difficult to use, or simply does not always work as designed, according to the study.

The second issue was the brutal winter, Mr. Sargent said. In warm-weather states, those surveyed reported the same number of problems as in 2013, which was 114 problems for every 100 vehicles. In cold-weather regions, they reported 117 problems per 100 vehicles, compared with 112 in 2013.

Of the 32 brands included in this year’s study, 13 improved, one stayed the same, and 18 did worse. Following Porsche, which had a score of 74 problems per 100 vehicles, in the top 10 were Jaguar (87), Lexus (92), Hyundai (94), Toyota (105), Chevrolet and Kia (tied at 106), BMW and Honda (tied at 108), and Lincoln (109).

The study found that Fiat had the most issues, with 206 problems per 100 vehicles. Rounding out the bottom five were Jeep (146), Mitsubishi (145), Scion (140), and Mazda (139).

The model with the fewest problems was the Porsche Panamera (62), followed by the Hyundai Accent (65).

Mr. Sargent would not name the vehicle with the most problems.

The most improved brand was Nissan, which fell last year because the introductions of three important vehicles — the Altima, Sentra, and Pathfinder — did not go well. This year, Nissan climbed to 19th place from 30th and had 22 fewer problems per 100 vehicles.

Ford moved up to 16th place from 27th and had 15 fewer problems per 100 vehicles than last year. The reason it fell — issues with the MyFord Touch infotainment system — is the same reason it improved.

“They’ve solved some of the infotainment issues and moved back up pretty quickly,” Mr. Sargent said.
