Took it in to the dealer, they tested and confirmed the cracks and LEAKING rear 'backlite' window. Service advisor was going to charge me $210 to evaluate/diagnose,..once they found it leaking he said he felt 'bad', and that it was only going to be $100,..then he said 'ah' I don't think I'll charge you anything...However, your vehicle is NOT covered for repair and that the estimated cost is $1,362 for a new backlite. He did not know anything about the TSB's, until I told/showed him, and in his service record he quoted a very old (12/7/21) TSB. I advised him that there was an updated 10/4/23 TSB, which he located but did not update in my service record. The next day I contacted RamCares via this site and they responded within 12 days, which I think is pretty good based upon other's experiences. I subsequently had a meeting with the Service Manager and showed him photo's of water running down around the RF Hub, Battery, pooling water on the inertia seat belt mechanism and elsewhere, MOLD growing and beginning to travel throughout, etc. That same day he contacted his District Manager and got approval for replacing the rear backlite and I'm now waiting for the parts to arrive. Hoping this resolves my issue and that the NEW Backlite frame holds up. Something interesting..On 11/20/23, in the mail, I did receive the CHMSL warranty extension, but not the one for the Backlite. When I looked at the CHMSL warranty extension online it showed an initial release date of 6/21/23..that is a 5 month delay?? This is what I queried RamCares about..'WHEN IS MY BACKLITE WARRANTY EXTENSION COMING'? (Also, update to my orig. post..My build date is January 2020, mileage 28,730, purchased 9/29/20). This is a bit 'long-winded' but there may be something above that will inform or help others.
