When I had my car detailed I noticed the metal surround that sits right below the license plate frame and surrounds the tailpipes was loose. Upon closer examination I could see that there was a fixture for 2 bolts to go through on the upper part but that there was no place to bolt them to. So I secured the piece with zip ties and made an appointment to bring the car into the local Acura dealer. The NSX tech there put the car up on a hoist and discovered that the brackets to run the bolts into must have broken off. Acura doesn't sell those separately as they are part of the rear diffuser. Anyway, my service advisor called and told me Acura was shipping a whole new rear diffuser out from Ohio and covering it under warranty. That piece costs about $11K. Has anyone else had this issue?
