I have a 2005 Jetta GLI and today when I put it in reverse my steering wheel started shaking. There was also a loud rattling noise. I put the car back into park and when I put it in reverse again the same thing happened. Finally, I restarted my car and it did not happen this time. Does anybody know what could cause this? I have to drive 4 hours every other weekend and I'm worried it will happen when I'm in the middle of nowhere!
