So I'm thinking about getting a G8 v6. But I'm reading about all these timing chain issues and it's starting to worry me. I don't want to be buying a car then worrying about if the chain is gonna need replaced. Is it a problem that will happen ? Or is it a small percent? Many of the G8s I'm looking at are between 45,000-75,000 miles. I know when I bought my 2012 Traverse I was advised to avoid the 2009-2010 traverses cause of timing chains. What's your thoughts?
