Buick, Jaguar dethrone Lexus in J.D. Power reliability survey 1Jaguar, the recently purchased offering of Tata Motors, Ltd., and Buick, the longstanding General Motors nameplate, have unseated Lexus as the most dependable automotive brands, according to J.D. Power & Associates.

For the past 15 years, Lexus had been the most reliable brand in the Vehicle Dependability Study. The  study measures problems experienced by original owners of three-year-old (2006 model year) vehicles. The study was redesigned this  to include 202 different problem symptoms across all areas of the vehicle.

Buick was ranked sixth last year; Jaguar placed 10th in 2008. Lexus followed the Jaguar-Buick tie, with Toyota and Mercury following closely.

The J.D. Power research details owners of Buick and Jaguar models reported an average of 122 problems per 100 vehicles, compared to 126 problems per 100 vehicle for Lexus owners.Buick, Jaguar dethrone Lexus in J.D. Power reliability survey 2

Lexus can, however, still lay claim to the most reliable vehicle, the LS430, with the fewest problems reported – just 61 for every 100 vehicles.

The survey company reported the slumping economy has resulted in car owners keeping their vehicles longer. The average length of car ownerships is now 73 minutes (6 years, 1 month), and increased from 66 months (5 years, 6 months) in 2006.

The survey also reported Mazda, Isuzu, Land Rover and Volkswagen with Suzuki (last position) are the  least reliable brands.

Toyota garnered five segment awards—more than any other nameplate in 2009—for the Highlander, Prius, Sequoia, Solara and Tundra. Lexus follows with four segment awards for the ES 330 (in a tie with the Acura RL), GX 470, LS 430 and SC 430. Lincoln captures two awards for the Mark LT and Zephyr.
