Japanese automakers are taking a beating in the latest J.D. Power study of new car owners, falling below the industry average for the first time in 29 years, while Korean brands continue to widen the quality gap with other automakers.
“This is a clear shift in the quality landscape,” said Renee Stephens, vice president of U.S. automotive quality at J.D. Power. “For so long, Japanese brands have been viewed by many as the gold standard in vehicle quality. While the Japanese automakers continue to make improvements, we’re seeing other brands, most notably Korean makes, really accelerating the rate of improvement.
"Leading companies are not only stepping up the pace of improvements on existing models, but are also working up front to launch vehicles with higher quality and more intuitive designs,” Stephens said.
The study examines problems experienced by vehicle owners during the first 90 days of ownership. Initial quality is determined by the number of problems experienced per 100 vehicles (PP100), with a lower score reflecting higher quality.
Overall, the industry experienced a 3% improvement over last year with 112 problems per 100 vehicles, compared with 116 ini 2014.
Koreans take the lead

In this year's study, officially called the J.D. Power 2015 Initial Quality Study, Korean brands lead the industry by the widest margin ever, averaging 90 PP100, which is an 11 PP100 improvement from 2014.
For the first time in the study, European brands (113 PP100) surpass Japanese brands (114 PP100), while domestic makes (114 PP100) equal the Japanese for only the second time.
Although Japanese brands overall experienced a 2 PP100 improvement from 2014, this has proven insufficient to keep pace with the industry, causing Japanese makes overall to fall below industry average for the first time in the 29-year history of the U.S. Initial Quality Study. Only four of the 10 Japanese brands included in the study posted an improvement.
Technology troublesome
Entertainment and connectivity systems remain the most problem-prone area for a third consecutive year, with voice recognition and Bluetooth pairing continuing to top the problem list.
The majority of models included in the study that have voice recognition systems experience 10 or more PP100 related to this feature.
The number of owners who indicate having voice recognition in their new vehicle has increased to 67 percent in 2015 from 57 percent in 2013.
“Smartphones have set high consumer expectations of how well technology should work, and automakers are struggling to match that success in their new vehicles,” said Stephens. “However, we are seeing some OEMs make important improvements along the way. What’s clear is that they can’t afford to wait for the next generation of models to launch before making important updates to these systems.”
Highest-ranked brands
For the third consecutive Porsche ranked highest in initial quality ,posting a score of 80 PP100. With a 20 PP100 improvement from 2014, Kia follows Porsche in the rankings at 86 PP100. This marks the first time in the history of the study that Kia has led all non-premium makes in initial quality.

Study details
The 2015 U.S. Initial Quality Study is based on responses from more than 84,000 purchasers and lessees of new 2015 model-year vehicles surveyed after 90 days of ownership.
The study, now in its 29th year, is based on a 233-question battery organized into eight problem categories designed to provide manufacturers with information to facilitate the identification of problems and drive product improvement. The study was fielded between February and May 2015.
