Emission Control problems of the 2001 Ford Escape

I received a warning light on the control panel of the car. Subsequently found that the differential pressure feedback egr (dpfe) sensor had failed. I see that many of the 2001 & 2002 Ford Escapes have this failure. Something was changed to resolve this as 2003 model does not appear to have problem (source autos. Msn. Com). Why should I pay $450 to correct a manufacturer fault.

The first incident happened on 05/01/06 after driving at least 30 min to 45 min. At a speed of around 50 mph, the check engine light came on. I took it to the dealer where they diagnosed a loose gas cap. On 5/22/06 after driving again at least 30 min to 45 min. After returning home and backing out of the driveway my Escape stalled and would not start, after about an hour it started again did not take it to the dealer. The third incident happened may 30 after driving 30 min to 45 min the check engine light came on again. I took it to the dealer where they replaced the vapor management valve which is still not correcting the problem, so they are talking about replacing the fuel tank. The dealer has been very helpful, but after five years I would think I would not have this problem.

Engine light stayed on. A foul smell seeped through the ventilation. As a result consumer vomited, and felt light headed.

While driving consumer smells fuel coming inside of vents . Dealership was aware of problem.

Consumer smells gas fumes inside vehicle, most often in morning, if fan is on or during short trips when turning vehicle on/off. Dealer checked it a month ago and found nothing. Problem is still occurs and they seem not to care. The dealer could not find the cause for the fume inside the vehicle.

While making a stop or restarting vehicle gas smell enter in side . Please provide further information.
