I have the same problem coming up when I press some key on my keyboard while being in the garage. But that's the only problem I have with the hud. And if I reboot the game and load my save again the problem is gone.
Yes. And I figured it out now -- this time for realz.

I tested this extensively now. And, indeed, it seems to be what's happening. The solution? Obviously, on my end, to be a bit more patient.
