NHTSA Complaint #11666880 — 2019 RAM 1500

2019 ram 1500 big horn rear back lite leak. Anytime it rains it pours from the frame where it has developed two cracks on either side of the power sliding window. Dealer states it needs replaced after resealing the window and the 3rd brake light. Dealer states Ram will not pay for the replacement even though there is an extended warranty for 8 years or 150k miles on the backlite. I have opened a case with customer care...all they do is mediate between you and dealer they have no access to TSB bulletins or service records. TSB bulletin located on NHSTA site states replacement. Dealer states they only reseal and that the one I can see is outdated. Dealer wrote on last service record that the backlite needs replaced. Note: there is a electronic hub located behind the seats. Also, potential mold growth as the vehicle has a persistent musty smell.
