Yea, im from Edmonton, it sucks too cause winter is just starting, first real snowfall this year, gonna be great when its -40 and a foot of snow. my brother brought it in to Nissan today. the foreman said he just had another altima with the same problem, the whole control assembly had to be changed for that one.
Sidenote: the car is a 3.5SR with 4400 km on it

wouldnt expect problems this early
