This is a much different rating system than others, and not sure what it exactly means:
Modern new cars and trucks suffer fewer mechanical breakdowns now than any of their predecessors — so much so that the key surveyors of quality among new vehicle owners has changed their methods. The latest version of the J.D. Power Initial Quality Survey released today focuses on design flaws rather than mechanical ones, a switch that elevates Porsche to the top of the industry and gives General Motors high marks, while forcing Ford to add buttons to its MyFordTouch entertainment system after a second year of subpar grades.
Using about 83,000 questionnaires from owners who bought new cars and trucks between November 2012 and February 2013, J.D. Power found that two-thirds of the complaints owners had dealt with technology inside the car, from navigation systems to confusing cruise controls to problems pairing their phones with Bluetooth. Under the Power study a complaint doesn't mean something's broken — just that it isn't working as the owner thinks it should be.
What that means is that Porsche and
GMC trucks have one thing is common: a lack of confusing technology features and touch screens. It doesn't have anything to do with quality or reliability, just complaints from new car customers about the confusing tech features in their cars.
