Buick, Lexus top J.D. Power survey, as vehicle service improves overall

Buick and Lexus returned to their customary place atop J.D. Power's scorecard of satisfaction with dealership service departments. In the Customer Service Index Study, out Thursday, Buick scored 860 on a 1,000-point scale for mass-market brands and has topped this ranking in three of the past four years. Lexus topped the list of luxury brands with a score of 874. Fiat and Land Rover were the bottom-dwellers in the two categories. Buick and Lexus also ranked highly in the research company's overall Vehicle Dependability Study rankings out recently. The customer experience at car dealerships has improved steadily, with the overall industry score rising in seven of the past eight years. And one statistic is particularly remarkable: 94 percent of customers say their car was fixed right the first time. The dominant area of difficulty in repairs seems to be infotainment systems. Only 80 percent of respondents said their stereo was fixed right the first time. And in last month's Vehicle Dependability Study, J.D. Power reported that infotainment systems were the most commonly reported vehicle issue, accounting for 22 percent of all problems reported, up 2 percent from the previous year. J.D. Power surveyed 70,000 customers for the Customer Service Index Study. For the Vehicle Dependability Study, it surveyed 35,186 first owners of 2014 model-year vehicles after three years of ownership. Below are charts for both the current study and the complementary overall brand dependability survey. Related video:

The Lexus LC 500h has a four-speed auto and that's a good thing

Lexus is sharing some powertrain details on the LC 500h ahead of the big hybrid coupe's debut in Geneva. Its new gas-electric setup strays from Toyota's tried-and-true system found in everything from the Prius to the Lexus GS. It's called the Multi Stage Hybrid System that's designed for performance vehicles, and it has an antiquated-sounding piece of equipment buried deep inside that's supposed to make it more enjoyable to drive. The basics: In the LC 500h, its first application, the Multi Stage Hybrid System will consist of a 3.5-liter V6, a hybrid transmission, and a lithium-ion battery pack. The hybrid transmission has an electric motor for motivation (and we're guessing a second for charging) and a four-speed automatic mounted to its rear, which either means inside or aft and in series. Why add ancient tech to a new hybrid system? Lexus says it preserves the connection between throttle input and engine speed that gets lost in a CVT. And while four seems like an insignificant sum in the face of nine- and 10-speed autos, remember that it is an infinite increase in gear count compared to CVT-packing hybrids. Toyota has been using versions of the Hybrid Synergy Drive system since the first Prius debuted in 1997, and the same system is sold under the Lexus Hybrid Drive banner in most of the luxury brand's offerings. These systems use what Toyota calls an e-CVT – two electric motors paired with a planetary gearset. This lets the engine and electric motors share the job of propelling the car – one motor handles charging of the battery and the other is primarily used to drive the wheels but can also recoup energy through regen. Like a conventional CVT, the planetary gearset arrangement allows the gas engine to run at its optimal engine speed when called upon for motivation and/or charging. But that doesn't make for the most exciting or familiar driving experience, as it affects both power delivery and the sound of the power being delivered. This is where the four-speed auto comes in. Based on the limited details Lexus has shared, our hunch is that the hybrid transmission will meld some form of the existing Lexus Hybrid Drive system with two more planetary gearsets, or the basic guts of a four-speed auto. This will provide the four fixed ratios and the feeling of actual shifting gears – because there will be actual gears shifting.

Lexus LF-LC Concept goes blue, remains happy

Until the day when we can see a production version of the Lexus LF-LC Concept, we'll just make do with seeing the sleek two-door in different colors for now. After first showing us the car in a Candy Apple Red color at the Detroit Auto Show, Lexus has brought its LF-LC Blue (in a deep ocean blue) from Down Under to LA.
Aside from the new color, there's nothing new for us to see here. That means we were still ogling over its flowing body lines, impressed by its 500-horsepower hybrid drive system and looking forward to possibly seeing the car go into production.
