TL-the contact owns a 2006 Hyundai Sonata. The contact stated that the fuel tank, the brake and fuel lines were severely rusted. In addition, the fuel lines were leaking. The vehicle was taken to the dealer where it was diagnosed that the fuel tank, the brake lines and fuel lines, and the cross members needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 33,000. Djr

Brought car into dealer as engine light was on. Dealer explained to me that I needed a new gas cap ($200). Did not fix problem and when returned to dealership I was told that I needed to replace the gas tank as it was rotted. I had owned the vehicle for a year but how does a 6 year old car have a rotted gas tank? dealership (balise Toyota, springfield, MA) claimed "well that is new england for ya". I am over 70 years old and have owned a number of cars in new england over the years, none of which have ever had a rotted gas tank.

Driving from bakersfield, ca to auburn, ca on 12-20-12. Filled with fuel about 15 miles before auburn. Parked in auburn, car would not start about 3 hrs later. Towed to garage on 12-21-12, started at garage, could find no problems. Drove from barstow, ca to payson, AZ on 12-27-12. Would not start next morning. Mechanic came on 12-30-12, car started. Had mechanic come on 1-16-13 to check fuel pump. Started to replace the electric fuel pump, found that the power connector from the pump to the connector at the top of the fuel tank had burnt, corroded. Discolored connections. This is inside the fuel tank! have had to order a new pump assembly from Hyundai. Don't if it is an upgraded part.
