No prior symptoms or warning lights the transfer case in my equinox went upon further research tons of equinox-??s and similar gm cars have had the same issue where a part inside the transfer case cause the case to crack and fluid to leak out if this happens when driving the car will become inoperable creating a safety hazard gm made a replacement transfer case without the issue but never issued a recall a quick look online and you will see a ton of consumer complaints related to this issue I do believe gm knew about it and instead of doing the right thing just made a replacement and left it at that.
