Car owners report more problems with their vehicles for a second straight year

The J.D. Power ratings examines problems experienced during the past 12 months by original owners of 2014 model-year vehicles.

Overall reliability is judged based on the number problems experienced per 100 vehicles (PP100) with a lower score reflecting fewer problems. Buick followed with a score of 126, and Mercedes-Benz rounded out the top five with 133.

With a score of 123, Toyota ranks third this year in the the J.D. Power U.S. Dependability Study, thanks to several models being ranked the highest in their segment: Prius (compact car), Camry (midsize car), Avalon (large car), Prius v (compact MPV), FJ Cruiser (compact SUV), Venza (midsize SUV) and Sienna (minivan). "While many expensive and niche vehicles do have excellent quality, the fact is that most consumers are shopping in the high-volume mainstream segments". The best-selling truck, the Ford F-150, and the best-selling vehicle, Toyota Camry, both led their respective categories in the survey. JD Power uses the survey results to work out how many problems per 100 cars (PP100) each manufacturer suffered, along with an industry average.

"In the current industry environment of record levels of leasing and long-term loans, higher residual values allow automakers to provide more competitive deals to buyers", said Jonathan Banks, vice president of vehicle analysis and analytics at J.D. Power. All Hyundai vehicles sold in the US are covered by the Hyundai Assurance program, which includes the 5-year/60,000-mile fully transferable new vehicle limited warranty, Hyundai's 10-year/100,000-mile powertrain limited warranty and five years of complimentary Roadside Assistance. Cars that have won awards are Ford F-15, Toyota Camry, Toyota Prius, Lexus ES, and Chevrolet Camaro.

Toyota Motor Corp. continues to lead the pack with two of the three top spots (Toyota and Lexus), and 10 segment awards, the most for any automaker in the study's history.
