Well, I spoke with the body shop at the dealer and he looked up the Vin and advised rust and corrosion warranty expired in 2018.
One thing I found in my research read
MOPAR COLLISION REPLACEMENT PARTS LIFETIME LIMITED WARRANTY
This warranty is not transferable to a subsequent owner of the vehicle. FCA US LLC warrants, to the original purchaser only, Mopar Replacement Sheet Metal products, including plastic bumper covers and grilles, against defects in material or workmanship for as long as the original purchaser owns the vehicle on which the part is installed.
This warranty includes perforation (metal rust-through) due to corrosion in normal use. Replacement sheet metal products which prove to be defective due to perforation (inside-out rust-through only) will be repaired or replaced at the option of FCA US LLC. If the vehicle is eight (8) model years old or more, FCA US LLC may replace the defective part with a comparable salvage part. This warranty covers the cost of parts, labor and paint for replacement parts, including outer-panel sheet metal parts, if incurred as a result of the failure; if preapproved by FCA US LLC; and if an authorized FCA US LLC dealer originally installed the part. Parts are covered on a replacement basis only, if the original part was sold over-the-counter. This warranty is not transferable.
WHAT IS NOT COVERED:
This warranty does not cover corrosion due to fire, accident, vehicle abuse, owner negligence or vehicle alteration; corrosion caused by sand, hail, airborne fallout, chemicals, salt, road hazards or stone damage; or surface paint deterioration or corrosion (other than inside-out perforation).
I realize this is points to collision replacement parts, but it is the only mention of rust and corrosion found so far.
Any of you have any rust and corrosion claims and if so what you were told. As previously stated I have just under 95,000 and no body damage except to two areas noted.
