| Gasoline Fuel System problems |
The contact owns a 2011 Hyundai Genesis coupe. The contact stated while driving at an undisclosed speed during a rainstorm, there was water leaking into the interior of the vehicle through the rear windshield. The contact observed mold developing throughout the interior of the vehicle. Later, the contact stated that upon attempting to start the vehicle, there was a fuel odor inside the vehicle. After a visual inspection, the contact observed fuel leaking in the engine compartment. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the fuel rail after observing a crack in the fuel rail. The vehicle was not repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA hotline for assistance. The failure mileage was 152,000.
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. If the mileage ratings had been more accurate I would not have even considered buying this car. Please recalculate the mileage ratings to accurately reflect what people will get.
