The fuel-efficient Hyundai Accent, which gets up to 35 miles per gallon on the highway, was named the most dependable sub-compact car by J. D. Power and Associates in its 2008 Vehicle Dependability Study (VDS). The study measures problems experienced by original owners of three-year-old (2005 model year) vehicles. The study is based on the responses of more than 52,000 owners of new vehicles bought between November 2004 and April 2005.
