Prospective buyers planning to splurge on a luxury car may want to reconsider. Mass-market brands now are more reliable than premium models.
For the first time in its 30-year vehicle-dependability study, J.D. Power found that mainstream brands ranked higher than upscale ones, based on problems per 100 vehicles for three-year-old autos. Nameplates from companies including Toyota Motor Corp., General Motors Co. and Hyundai Motor Co. had an average of 135 problems, six fewer than for brands such as BMW AG’s namesake line and Daimler AG’s Mercedes-Benz.
