I have a 2021, discovered the leak due to this thread at 200 miles on the odometer (guessing it was always there). Rained pretty hard the last few days and the leak is pretty bad on both sides. Should I have the dealer repair now, or wait until a potential better solution is found?
I am inclined to get it repaired now because it seems most likely that GM will continue to band-aid this situation for eternity.
Thoughts?
I ordered this exact Amazon Trim-Lok product, but I cannot get it to fit into the upper gap of the spoiler. I even tried lubricating it with some silicone spray. How did you guys do it?
I have owned both the 8 speed and now the 10 speed, and I can't say enough how much of a difference this 10 speed makes. I love it. I would go TB route on that difference alone.
Do you mind sharing your specific technique you used with the Kent application?
I have a 2021 Trail boss and after reading this thread, am considering doing the sealant repair myself. I traded in a Yukon Denali with the 8 speed, with nothing but issues, and already working on this next issue with the TB now. Slightly disappointed to say the least. Come on GM.
