The firm establishes a ranking on JD Power Vehicle Dependability

A survey conducted by the American firm JD Power and Associates concluded that motor vehicles are more reliable than ever.

A statement of the trouble PROVEN last year by the owners of vehicles aged three years indicates that the number of problems was lower than five percent was the worst year since 1989, or that JD Power has undertaken such an annual study.

They are the owners of vehicles Lexus, Porsche, Toyota and Lincoln who earns the least trouble in 2012, while those who reported the most owned Jeep, Mitsubishi, Dodge and Land Rover.

On average, motorists have reported 126 problems per 100 vehicles sample, six troubles less than what was reported a year ago. And for the first time, new models or those that have been redesigned performed better than those who had not been modified since 2009.

This contradicts the assumption that it is best to avoid a new model to not be plagued with defects related to his youth.

Ram trucks, manufactured by Chrysler, passes are 29th to 9th place, a remarkable bond, according to the study. Suzuki and Mazda then progresses as Scion, a subsidiary of Toyota, down 13 places. Cadillac, Audi, Volvo and Mitsubishi also tumbled.

The most reliable subcompact was the Toyota Prius. Among the intermediate, the first place goes to the Hyundai Sonata.

Toyota RAV-4 was deemed best sport utility vehicle (SUV) and compact among the largest SUV, the first rank is assigned to the Chevrolet Tahoe.

JD Power claims that 54 percent of owners with no trouble experienced with their vehicle will choose the same brand for their next purchase.

The 2013 study, which was unveiled Wednesday, compiles responses from 37,000 owners of vehicles of the year in 2010 after three years of use.
