At 63000 miles my Pacifica is needing a head gasket replacement that was leaking coolant into the combustion chamber. I am concerned that even after the fix, the long term problems that might continue. Seems an unusual problem at such low millage. I have been reading about similar issues on this forum. Total cost for repairs is over $4000. Outside of the warranty Chrysler is offering no support. Has anyone garnered any support from Chrysler regarding similar problems? So disappointed in this brand. Any feedback would be appreciated.
