J.D. Power and Associates' closely-watched 2012 Initial Quality Survey has just been released, and the news is mostly good. For the second consecutive year, Lexus takes the overall IQS crown, with Jaguar, Porsche, Cadillac, and Honda rounding out the top five. Porsche disrupted Lexus' winning streak in 2010, when Lexus came in fourth.

Overall quality improved industry-wide, with average problems per 100 vehicles dropping by five to 102, a five percent improvement over the average in the 2011 study. However, complaints about audio, entertainment, and navigation systems increased by eight percent over last year. More notably, complaints in that area have risen 45 percent since 2006 while complaints in other categories have decreased by 24 percent over the same period.

Of the 10 Truck/Multi-Activity Vehicle segments, General Motors products took three of the top spots: The Buick Enclave in the Midsize Crossover/SUV category, the Cadillac Escalade in the Large Premium Crossover/SUV category, and the GMC Sierra 1500 in the Large Pickup category. Nissan had three winners: The Infiniti EX in the Entry Premium Crossover/SUV category, the Frontier in the Midsize Pickup category, and the Nissan Quest in the Minivan segment.

Of the truck and SUV-specific brands, all showed an improvement in the number of problems per 100 vehicles, but relative rankings were mixed. GMC ranked 12th this year, down two spots from its 2011 ranking, but owners reported five fewer problems per 100 vehicles than last year. Jeep climbed two spots to 23 and showed a dramatic improvement in their problem score, going from 122 in 2011 to 110 in 2012. Land Rover dropped two places to 28 and only saw a small improvement in their score from 123 to 119. The most-improved truck and SUV brand was Ram, which climbed eight spots to place 14th overall, and saw problems per 100 vehicles plummet from 114 in 2011 to 99 this year, below the industry average.

For the plant assembly line quality award, Toyota won big. Three of its plants that produce SUVs -- two in Canada, and one in Japan -- winning. Including plants that produce cars, Toyota represented five out of the 11 factories. Toyota's Cambridge South, Ontario plant, which builds the Lexus RX, and its Woodstock, Ontario plant, which builds the Toyota RAV4 for the North American market, took Silver and Bronze respectively for plants in North and South America. Toyota also took Silver in the Asia Pacific region for its Kyushu 2 plant, which also produces the Lexus RX.
