My 21 RS has the same handling issue. I have the 265/45/R21 tire option. Took it to the dealer twice. Last visit cost me a wheel alignment and tire balance (both were mildly out of adjustment). They claim there is nothing wrong. It oversteers (torque steers) at half throttle while changing lanes and on ice it seams to wonder, even at 50km/hr.

Update on my experience. Vehicle was like this since new. I complained about it at 11,000 km this summer (no icy conditions) and they said the wheel alignment tester said it's in spec. I told the dealership last week (17,000 km) that it must be a wheel alignment issue. First they had to replace the rear driveshaft (main reason I took it in), they did a wheel balance and wheel alignment (charged me for that) and said both were out. The vehicle stability was still shit! I took it back yesterday and told them I think the wheel alignment is still out. Today they told me they had a junior tech do the alignment and the alignment was still out. WTF! They re-did the wheel alignment and now it handled properly. So, it was the wheel alignment all along. I also noticed torque steer with this vehicle but they can't fix that without a different axle design.

That sounds like my problem I had as posted above. When the wheel alignment was done properly, the vehicle drives like it should and I felt confident in the vehicle again. The wheel alignment issue will only show itself by the wear off the tires after 10,000 miles, icy patches or the pot hole scenario you explained. Make sure the dealership can do it properly and provide you with the before and after measurements.
