My belt has started to make some noise over the last couple days under moderate load after the engine is warm. 9900 miles. I looked at the belt on the pulley and the clearance seems correct, so I'll just take mine into the dealership and have them look at it (and knock out the 10k service while they're at it). I'll keep you posted.

In regards to overheating and coolant tanks exploding... if your belt comes off, dash lights will come on. If dash lights come on, PULL OVER IMMEDIATELY and shut the car off. The belt coming off is not a major issue as long as you don't keep driving the car.

Quick update: I took it to the dealership and they were unable to reproduce the issue. They checked tension and visually inspected belt and pulleys and found no issues. I told them the engine has to be hot, and they want to keep the car overnight for diagnosis, but I'm holding off on that. The problem has lessened dramatically now, to the point where I only very occasionally hear a little squeal under heavy load. I'm going to keep an eye on it to see if it goes all the way away.

One thing I learned at the dealership though: one of the techs there said that his 3.0T (premium) had a leaking water pump that leaked on his belt and caused it to squeal. They found no leaks in my car, but it might be something to keep an eye out for on yours.
