Car was making some annoying rattle noise when engine warmed up. Took it to the Honda dealer and in less than 30 seconds during the test drive, the mechanic thinks he knew what it was so I drove straight back to the workshop and five minutes later.....hey presto the problem's gone. It was screw or nut that was loose. The best thing about this was the dealer didn't charge me penny!!!!!!!!!!!!! Very happy bunny.
