In the US, J.D. Power surveys are regarded as the best measurement tools for assessing the reliability and quality of vehicles. The surveys are conducted by owners of the makes and models being assessed, and in this Initial Quality test, the results were collected from over 83,000 owners of new 2013 vehicles after the first 90 days of ownership.

Some revisions were made to the 233-question survey this year for more comprehensive and more specific answers to questions. The firm says,

“The study has been enhanced to better measure the quality of today’s vehicles, particularly problems related to new technologies and features now being offered.”

Each vehicle is given a score in regards to problems per 100 vehicles (PP100). So how have manufacturers improved? Well, in 2012, Lexus came out on top, followed by Jaguar and Porsche.

This year, Porsche climbed to number one spot with 80 PP100, followed by US truck manufacturer GMC with 90 PP100, and then Lexus with 94 PP100.
