Lexus, Buick top J.D. Power reliability survey, but tech bugs still common

The J.D. Power Vehicle Dependability Study, a two-decade look at the problems in cars and trucks after three years of ownership, has been a glass half-full/half-empty exercise for a few years now. If you're an optimist, you'd say the list of most-reported faults — led by bad Bluetooth connections and poor understanding of voice commands — are the very definition of #firstworldproblems.

But this year survey contends those problems are becoming a defining part of owning a vehicle in the 21st century, and will be the difference between a car owner who comes back for more and one who decides to pair their smartphones with another brand.
