Buick has reclaimed the title as the most dependable mass-market brand after three years of vehicle ownership while luxury marque Lexus again topped the industry, according to J.D. Power.
Buick led the mass-market segment with 116 reported problems per 100 vehicles, 10 fewer than last year. That was good for third place overall and its third mass-market win in four years.
Toyota Motor Corp.'s Lexus topped the chart as the most dependable brand for the seventh year in a row, followed by Porsche, according to J.D. Power's annual U.S. Vehicle Dependability Study, released Wednesday.
Dependability is measured by the number of problems experienced per 100 vehicles, with a lower score signifying higher quality. This year's study assesses vehicles from the 2015 model year.
Rounding out the top five brands were Infiniti and Kia.
Infiniti saw the biggest improvement in ranking this year. It soared to No. 4, from a bottom-five finish in 2017, with 83 fewer problems per 100 vehicles. Kia's fifth place spot marks the brand's "best-ever" performance, according to J.D. Power, with 26 fewer problems compared with last year.
Jaguar, Honda and Mercedes-Benz fell from the top 10 this year. Lincoln joined the ranks along with Kia and Infiniti.
The industry overall improved for the first time since 2013. The average score came in at 142 problems per 100 vehicles -- or down 14 problems -- from 2017, for a 9 percent improvement.
