“This vehicle was purchase new on 2/4/11. It is rated at 20 mpg city 30 mpg highway. The mileage has consistently been poor. It now has 4200 miles on it and highway mileage with the cruise control on, in warm weather, with no load other than the driver is around 24 mpg. I had it checked by Hyundai and they replaced the 02 sensor. This improved the highway mileage slightly from 23 to 24 mpg. It has never approached 25 mpg let alone 30 mpg. I have read about others complaining about the poor mileage on 4 cylinder Genesis coupes. …”
NHTSA complaint #10415675, filed 2011-07, 200 miles“Car loss all forward power, speed dropped to 20 MPH accelerator had no effect. After pulling to side of road engine would not go above 2000 RPM in neutral. Engine light came on, limped to dealer. Dealer diagnosed as trouble code c15, throttle body assy. Dealer replaced throttle body, drove car for 50 miles in 4 days. Now have the same problem, engine light on and no power. This is a very dangerous problem. Will have car towed back to dealer. Loosing power with no warning while driving on the interstates or pulling out into traffic is dangerous and safety problem!!!!!!!”
