I've always assumed the timing chain issues are a Ford thing. Their 3.5 Ecoboost has had a terrible time with stretched chains.

I think Jymmie is right that it's been blown out of proportion. It's mostly the early ones. I know everybody says they stretch and other manufacturers have that problem. But I've laid out every chain I've replaced with the chain I took out an have not seen any signs of stretching. I think they get worn from the 16,000 mile oil change interval. When they get loose enough to jump time it's usually because of some major failure in the tensioners or guides.

As I've said since 2003, oil is FAR less expensive than an engine!
