On oct 20,2006 my third (emission failure) has happened to my Chrysler Pacifica 2004 fwd model (48,535 miles). This model had problems in the past-most have been corrected. The first was engine stalling, which was repaired with updated software. The next was my a/c control/hvac unit which would not light, noise from bushings was replaced. Flickering of dash lights time to time is an issue-the current major problem is that it will not pass emissions on three occasions it has failed next visit will be to the dealer on oct 30,2006- nys inspector/mechanic has told me that the pc in albany in nys may not read all codes all places show -oxygen sensor and cat sensor as being down and not ready on the print report-third mechanic thinks it is under warranty which si should be and that it may be the ecm or bus section of the module-this is based on a scan test and a obd2 system. Failures = 3 nys inspection fails -4th will be at the dealership-consequences hoping to get it repaired as soon as possible.
