I bought a 2010 Legacy 2.0 Diesel two weeks ago. As I was maneuvering on full lock to park into this tiny spot, the steering wheel suddenly become exceedingly heavy, almost with complete locking of the wheel. I restarted the car several times with no luck, I couldnt turn the wheel either direction. No noise coming from the car whatsoever. Funny thing is, as soon as I hit the gas (its a manual) the wheel started responding, so it was locked only at idle. I managed to drive home like that, but i felt that the wheel was becoming very heavy every now and then during this ride home. Even more funnier, the steering was just fine this morning, everything looked and felt normal!
Any ideas what the problem could be?
