Porsche and Lincoln Top J.D. Power's 2010 Dependability Study, Cadillac DTS Has the Fewest Problems in the Industry

J.D. Power & Associates' latest vehicle dependability study says most cars are getting better. In fact, J.D. Power tests showed that 25 of 36 brands (69%) improved their long-term durability. Reported problems decreased from an industry average of 167 per 100 vehicles last year to the current 155 (+7% in reliability).

The study, which measures problems experienced by original owners of three-year-old (2007 model year) vehicles, said that Porsche was the highest-ranking brand with 110 problems per 100 vehicles followed by Lincoln (114 problems) and Buick (115 problems).
The Cadillac DTS is the model with the fewest problems in the industry, with just 76 issues per 100 vehicles. This marks the first time in more than a decade that a model from a domestic automaker has achieved the lowest PP100 score in the Vehicle Dependability Study.
Interestingly, seven of the 10 models with the lowest incidence of problems in the industry are from Ford and General Motors, including the 2007 model-year Buick Lacrosse, Buick Lucerne, Cadillac DTS, Ford Five Hundred, Lincoln MKZ, Mercury Milan, and Mercury Montego.
The biggest losers in terms of increases in problems per 100 vehicles are: Land Rover (+27), Audi (+25), Mitsubishi (+20).
The brands with the most problems per 100 vehicles in the industry are: Volkswagen (225), Suzuki (253) and Land Rover (255).
