I own a 2005 Pontiac G6 and I've been having a clunking noise coming from the steering. My mechanic tells me though it is annoying, it's not a safety issue and it won't give out. Should I be worried about this? I am a person who does alot of travelling with my family and knowing I have this problem is a bit scary. I've spoken to other G6 owners and most, if not all of them has had the same problem. After they had it fixed, the problem still comes back. Anybody have any advice on this issue?
