 I bought the car used a little over 2 years ago. It had high mileage but the price was right and I trusted the Hyundai brand. Boy was I wrong. The car functioned fairly well for the first 2 years, I was getting the street mileage ( 26 mpg) but was no where close to the highway mileage (35 mpg). Then in April my mileage suddenly dropped. Since then I now average 20 mpg, which is 200 miles per tank. Basically I can no longer afford to drive the car. I contacted Hyundai who told me to take it to their service dept. I have spent over $500 to try and figure out the issue. The only thing left to try is the fuel consumption test, which I am saving up for.
