23 Trail Boss issues

[mugsyboegs]

Bought my 23 Trail Boss with 20,000 miles on it. At 29,000 miles I brought it in for an alert that kept showing "Service brake sensor". They ended up needing to replace the Brake Master Cylinder and was at the dealership for 3 weeks. Within a month I started to see the same alert pop back up again. That brings me to today, as I had to bring my truck into a dealership while on my way to an out of town tournament. I had like 6 alerts all pop up at the same time. Brake fluid low, service ESC, Automatic braking system error, and others I can't remember right now.
My question is, how common is this for a truck with 35,000 miles on it. Do I even want to deal with this headache of a truck anymore? This is the first truck that I have owned. Thought and/or advice would be helpful, thanks.
