NASHVILLE -- The entire auto industry got a little bit better on quality this year, but few brands jumped up the charts the way Infiniti did.
Infiniti leapt into fifth place on this year's J.D. Power Initial Quality Study ranking, up from a below-industry-average 23rd place in 2014. The study ranks brands by problems reported by new-vehicle buyers in the first 90 days of ownership.
Infiniti says it rose by targeting and improving two of its biggest problem areas: software problems on the Q50 sedan's InTouch telematics systems and a rough transmission on the QX60 SUV.
