2010 Nitro bought April 2010. Called dealer to schedule a defect and was told to bring the car to the dealer. The sun roof visor constantly rattles and the clock looses approx. 5 minutes per month. The serv ice department stated all Nitros sun roof visors rattle and that i would have to "live with it". The service department also stated they could not duplilcate the clock error and therefore was would not repair. Thanks for your help. Donnie Dixon e-mail: [email protected].
