We have had some extreme winter weather here in the past week - about 8 inches of powder snow in a couple of days, with -20 C / -4 F temperatures, then a one day warm-up Wednesday to +8 C/ +46 F, then back down overnight last night to -12 C / 10 F and colder today at -18 C / 0 F. I drove my 997.2 2wd GTS for a couple of hours on Wednesday, and the snow had filled up the radiator inlets in the front and was packed in the wheels and fender wells when I put the car in the garage Wednesday afternoon. This evening I went out to do a quick run...and the front wheels were frozen solid. So solid they wouldn't rotate as I backed out of the garage. I thought they would break free if I just kept moving back slowly, but they continued sliding (both sides) until my rear wheels hit the snow in the alleyway outside the garage and I no longer had the traction required to drag the front of the car. A couple of 2-liter bottles of hot water poured onto the front wheels/rotors/hubs freed everything up and I was on my way. I've never experienced or even heard of such a situation in 44 years of driving in Western Canadian winters.
