Sadly to say I have a major issue with my '09 DI RWD with 11000mi. The dealership who has been very helpfull and has tried to resolve my problem is now stumped after the fifth time in. Problem is that there is a loud metal on metal clunk upon acceleration, changing direction etc. They have replaced all of the bushings, both rear knuckles, checked backlash and re-torqued everything and still it keeps getting worse. Just curious if anyone has experience with a buy back?
