I am taking my 2020 1500, with rear window slider, into the dealer this week regarding LEAKS. I noticed a water drip line on the 'top inside' of the rear window which I thought may indicate the 3rd 'upper' brake light leaking. Then while investigating I noticed (small, very hard to see) 2 cracks in the upper portion of the plastic window frame. Then felt around under the seat and found a damp towel. There are two TSB's for years 2019-2021, that address both the 3rd brake light leak (TSB 23-074-23) and the rear window leak (TSB 23-098-23). These also extend the warranty period for the issues to 10 years and 8 years. Hope mine...And yours are covered.
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.
