I have not heard of a frozen zoom that often. Mostly, I've just heard of SDM issues. My lens was stuck at 16 mm, but took fine photos there. I tried to determine if I had somehow caused the frozen zoom problem. It occurred near the end of a 9-day trip to US national parks in Utah and Arizona. Camera and lens was in and out of a backpack often, backpack was set down on rocks and picked up a lot. The lens was never abused or dropped, but it was handled often. So maybe I did something, or maybe not. I was not able to get any understanding from Precision if my practice was too rough for the lens. I thought it was acceptably gentle handling, but there the lens was frozen, so maybe I actually helped cause it somehow.
