This is weird, the power steering in my 06 Si went out the other night. This is my 3rd winter with this car and I've never had a problem with the power steering before. As soon as I started up the car, I turned the wheel a little and it locked up right away. I turned off the car, restarted it, and it's worked fine. I have 28,000 miles on my car and I really hope if there is a problem it will happen before my warranty is up.
[Edit] It wasn't even that cold outside, maybe 30 F and my car is stock (but I do have an HID kit, but I doubt that affects my electrical power steering).
