1. 2010 Hyundai Genesis Sedan
Topping the charts, or rather bottoming them out is the 2010 Hyundai Genesis Sedan. This large, rear-wheel-drive four-door plummeted like a meteor in J.D. Power’s latest quality survey. The car declined by a whopping 114 problems per 100 vehicles, a devastating drop that resulted in an overall score of 195 PP100. Owners reported having issues with the seat memory and ventilation systems as well as the power tilt/telescoping steering column. For a little perspective the Genesis sedan’s decline was exactly TWICE the overall number of problems per 100 vehicles reported by Lexus RX owners, the highest-rated vehicle in the 2013 survey. Its overall score was just 57 PP100.
