199K Miles. Yeah - the serpentine belt came off so I had to pull off the road and get a tow home. I had heard an intermittent whine prior to the failure but thought it was coming from the power steering pump. I was actually returning from a road trip so had been driving for about 10 hours when it happened.
The back side of the bracket failed with bits of debris falling inside the timing belt compartment - so was probably lucky that nothing got caught up in the timing belt. The crank sensor was covered in metal shavings - as you can see in the picture below.
Since I was changing out the fan bracket, I did the timing belt, water pump, cam and crank seals etc.
