J.D. Power & Associates released its findings from its 2013 U.S. Initial Quality Study (IQS), which serves as a benchmark for new-vehicle quality. Now in its 27th year, it has been redesigned for 2013 to better measure the quality of today’s vehicles, according to J.D. Power.

For the 2013 IQS rankings, General Motors received a total of eight segment awards, with its Chevrolet brand receiving five segment awards for the Impala, Silverado HD, Tahoe, Avalanche and Camaro. Its GMC brand received an award for the Sierra LD. The Buick brand received an award for the Encore, and Cadillac for the Escalade.

Other brands and models receiving awards include: Chrysler Town & Country, Ford Mustang, Honda Civic and CR-V, Mazda Mazda2 and MX-5 Miata, Porsche Boxster and 911, Acura TL, Hyundai Genesis, Infiniti FX, Mercedes-Benz GLK-Class, Nissan Murano, smart fortwo and Toyota Camry.

Toyota’s Lexus brand received the best score in the large premium car segment and the lowest average number of problems among all models in J.D. Power’s 2013 IQS.

The 2013 IQS is based on responses from more than 83,000 purchasers and lessees of new 2013 model-year vehicles surveyed after 90 days of ownership between February and May 2013.
