My car stalled at an intersection light. It was driving poorly-making loud noises and sticking as I pressed the gas pedal as if the transmission was going out. We were told it was covered under the powertrain warranty and we took it in to Ford. They told us it was the timing chain but because there was evidence of sludge, the warranty claim was denied by Ford. They claim we did not maintain our vehicle. We believe it is a defect in the system. We have maintained the oil on a regular basis and have had other major repairs with this car. It has had a new transmission at 35,000 as well as a new suspension system and electrical failure with the stereo/dvd system. There has never been any prior evidence of sludge. An accident could have occurred when the car stalled.
