Hell, I got this issue now too! I replaced the front shock absorbers and that's it! Nothing done at the back. No adjustments to any parts that should have an impact on steering or alignment, but the steering wheel is now off centre by a noticable amount.
Granted, the strut forced the wheel in an akward position full force, so in theory it might have bent or stretched something, but that does not explain at all why my wheels are still spot on aligned. It's only the steering wheel that is misaligned. Also, the drive shaft moves and "locks in" in different positions, but again it should affect only one side of the alignment, not both.
To fix this, I could adjust both tie rod ends equal amounts, but if the current issue were to be spontaneously fixed, I would have to revert the tie rod settings. Does anyone have a clue why this might happen?
