I keep several store-bought bottles of water, often refilled, in my car all the time. Usually the kids or I will use them and I'll replace or refill them, so none are much more than a month or so old. But they do freeze/thaw several times before being discarded, and I've never had one burst or leak (unless the cap was loose). Even the new/thin Poland Spring bottles have survived multiple freeze/thaw cycles.

I also have 8 foil (Mylar?) packets of "emergency water" in my car emergency kit with a 5-year shelf life (along with a 2400-calorie food bar). They have withstood 2 winters so far without any evidence of weakening.
