2001 Ford Escape exhaust system problems

Submission from re ford escape 2001 safety recall notice 11s24 *tgw the consumer received a recall notice in jan 2012. The notice indicated she would be informed when the parts required to complete the safety recall would become available, which wouldn't be until the second quarter. The vehicle caught on fire while parked, which was prior to the recall, but was quickly extinguished. Shortly after the fire, the vehicle was repaired.

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.
