WESTLAKE VILLAGE, California — Lexus ranks highest in vehicle dependability among all nameplates for a fourth consecutive year, according to the J.D. Power 2015 U.S. Vehicle Dependability Study released on Wednesday.
Buick made a big leap into second place, up three spots from the 2014 survey.
Fiat came in last in the nameplate rankings.
General Motors and Toyota each received seven vehicle segment awards.
The study measures the number of owner-reported problems of 2012 model year vehicles in their third year of ownership. It is based on responses from more than 34,000 original owners.
Respondents tended to gripe about technology issues, most notably problems with Bluetooth connectivity and voice recognition.
Fifty-five percent of owners said they couldn't hook up their phone to their vehicle and 31 percent say the phone would not automatically connect when they entered their vehicle.
"As we've seen in our Initial Quality Study, owners view in-vehicle technology issues as significant problems and they typically don't go away after the ownership honeymoon period is over," said Renee Stephens, vice president of U.S. automotive at J.D. Power, in a statement.
Power notes that issues with technology "impact overall dependability."
The study also noted, "The number of engine/transmission problems remains high."
Nearly 30 percent of the reported powertrain problems are a result of automatic transmission hesitation and rough shifting.
Edmunds says: Car shoppers get some critical information about vehicle dependability drawn from a large pool of owners.
