UPDATE 2: the dealer says everything is normal, the ECU is trying to prevent damage to the electric power steering system under excessive load. My trouble is, that I can give this "excessive load" during parking into a tight space. Isn't this faulty design? Any suggestions for improvement (other than my driving skills)? Apparently, some driving schools who own Subaru's also complained about this problem, and maybe Subaru fixed it in later models (2010 and up). My car is the first version of the new, 5th gen, Legacy.

i am bought the car from a german dealer, its still under warranty. I took it to the dealer, they took one day and couldnt find anything and sent me home. They said they checked the whole system. But I reproduced the same problem again today: When the car is warm and is idling, I turn the steering wheel right and left a few times and it starts becoming very heavy. After a few more turns, it becomes completely stuck. The problem goes away after the car is turned off and cools down in half an hour or so.

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?
