I’ve been following several rear window leak threads and I figured my 2022 would have this window leak problem at some point towing 7k# enclosed car hauler 60% of the time. Yep, last week with 33k miles and 30 months old a small leak started that runs down the window on the passenger side tight up against the pillar. Noticed it right away and used a towel to keep it contained. I have the Maximum Care 7yr/100k warranty as well.
I’m not having my vehicle tied up to have this window replaced only to find out it leaks again like some others have had after replacement. It’s an inferior design / manufacture and installation. I get it and here’s what I did.
Went to Autozone and purchased 3 tubes ($25) of Permatex 81730 Windshield & Glass Sealant 1.5oz. It dries clear. Taped off the window with Frogtape that is superior to that blue painters tape. I left the CHMSL in place and taped it off. Started on passenger side, used the majority of one tube filling until level up to the sliding window. It flows nicely. Wiped it smooth and then immediately removed the tape before doing the drivers side. Did same and finished with the center window last. I used every last bit of sealant and could have used slightly more. I cleaned anything that got on the window front or paint with lighter fluid.
It looks perfect, and standing on the ground you can’t see it. Haven’t had it in the rain yet, but I’m assuming it’s fixed. For me traveling/ towing the upper Midwest roads that are some of the worst this is a better choice for permanent repair that only took 2 hrs.
