I just bought the 2017 Titian Pro-4x about three months ago. After taking it on dirt roads for the first time it developed a slight squeal when applying the breaks. Took it to the deal thinking I picked up a rock, they couldn't find anything. I've taken it to the dealer about 9 times now for the same problem and they worked on the front breaks to no effect and turned the rear rosters the last time to no effect. Yesterday while at a dead stop I felt a vibration in the break pedal and it squealed at the same time. The service reps have driven the truck several times to get it to squeal and they say it doesn't with them. I'm getting very annoyed that I'm having this problem. Any ideas on what it could be?

So if you're wanting the dealership to fix it/pay for whatever went wrong, then I advise asking if the technician can ride along while you drive to re-create the problem/sound.

Otherwise by next recommendation would be to pull all the pads and rotors, clean it down. Check if you've got a hanging/stuck piston that's intermittent.
