Years ago my mom had a Honda Odyssey van that developed a jingly-rattly sound after she picked it up from the dealership after service. They couldn't find a thing wrong after multiple return appointments about the issue. Mom eventually went to a different dealer where they found a ratchet socket on top of the transmission. Lo and behold, the sound never reoccurred.
