Water pump failed, but this is the third time at the dealership

So a little backstory. About two months ago I brought my car into the local Ford dealership. I have a 2013 Ford Escape SE 1.6L (I believe) with approx 74k miles. I also believe it has a 2012 assembly date. I bought it used and am operating through an extended warranty. First, I needed a new coolant bypass solenoid valve, which seemed to be a simple enough fix. I did see something about there being a recall on this part which I did not learn until now. A week or two later, my Turbo went. I took it in, which ended up being a month without my car because after they replace the Turbo, I also ended up needing a new vacuum pump and they had to clean the valve covers because they were sticking. They weren't able to actually tell me if the vacuum pump needed replaced because the sticky valve covers were discovered after, which is why the air pressure (or whatever the technical terminology is) was not building properly. Now I have a water pump failure and need a new belt. I found out because when I turned my car on, it said the coolant levels were low and needed serviced. Within two minutes, it said the engine was too hot and to pull over somewhere safe to stop. I had to tow it back because it would not accelerate the two miles down the road to take it myself. This is the third trip to the dealership for repairs in two months.I want to know if the previous repairs could have been linked to this current repair. I have to go through an approval process for the extended warranty each time and have had to pay for multiple rentals. I love this car when it works, but lately I can't tell if it's bad luck, a possible lemon law issue, or incompetent technicians. Any advise is appreciated.
