The J. D. Power and Associates has released a report on long-term reliability of new vehicles. Performance metrics are measured based on “problems per 100 vehicles” (PP100). A lower PP100 score means that the vehicle is more dependable. The study is based on the survey results from 52,000 original owners of 2007 model year vehicles.
The report has found that 25 out of 36 auto brands have shown improvements in long term reliability when compared to 2009. Furthermore, the average PP100 for 2010 has dropped to 155, a 7% improvement from last year.
This year’s vehicle reliability award goes to Porsche, which received perfect scores in almost every category. Other top performers include: Buick, Lexus, Lincoln, and Mercury (a division of Ford in U.S.). All of them received five-star dependability rating. Other honourable brands that have earned four-star rating are Honda and Toyota.
Brands with the worst reliability ratings are: Jeep, Land Rover, and Suzuki. All of them received a two-star rating in every category.
