Was wondering how you got such a letter? My dealer is saying my 2004. 5 ECM is bad & wants $2050 for a new one. Naturally, I declined but am now worried that I may need one at some point.Just got a letter from Chrysler saying warranty on (ecm) has been extended to lifetime coverage. applies to2004-2005. 2500/3500 5. 9 engine trucks with California Emissions. Because of some failure at smog test![]()
