The nissan dealership has looked at my xterra and found that a nut welded to the frame from the inside has broken free of the frame. this is causing my suspension noise/issue. the problem i am having is nissan does not want to fix my problem. the dealership is waiting on nissan to give the go ahead to schedule repairs but they/i can't get nissan to move forward with the repairs. the noise is getting worse and i am afraid it will lead to a safety issue if not handled soon. the last i have heard was on august 13th the dealership was waiting to hear back from nissan but several calls to nissan has turned up nothing i can't even talk to a supervisor or anything.
