(Bloomberg) -- General Motors Co. and Toyota Motor Corp. dominated J.D. Power’s latest U.S. vehicle dependability study, as auto owners reported more problems overall because of technologies including voice recognition and navigation systems.

GM landed three brands in the top 10 and had the leading vehicle in eight categories, more than any other automaker. Toyota’s Lexus luxury division captured the No. 1 spot for the fifth year in a row, the company’s namesake brand ranked fourth and six of its models led their categories. The market research firm’s annual study is based on reports from owners after three years.

The study, released Wednesday, is a benchmark watched by automakers and consumers. J.D. Power again cited technology issues as the industry average rose to 152 problems per 100 vehicles, from 147 a year earlier. Infotainment, navigation and in-vehicle communications systems now account for 20% of all issues reported by customers, the firm said in a statement.
