This year's study is based on the experiences of 34,000 US owners of 2012 model year vehicles, meaning that many of these cars were purchased in 2011.
The top two issues reported in this year's survey were Bluetooth pairing and voice recognition systems misinterpreting users' commands. This closely aligns with the findings J.D. Power's 2014 initial quality survey.
55 percent of respondents who had Bluetooth problems said that their cars didn't recognise their phones at all, while 31 percent claimed that their cars wouldn't automatically reconnect with the mobiles.
According to J.D. Power, the quantity of drivetrain problems being reported "remains high". Almost 30 percent of drivetrain issues related to automatic transmissions either shifting roughly or hesitating.
As far as overall reliability is concerned, Lexus finished well ahead of Buick and Toyota, which came in second and third respectively. Cadillac finished in fourth position, while Honda and Porsche were tied for fifth.
