I purchased the car new on september 18,2015. having the car for 3 months i have been at the service department 3 times. i got home the first day and the belt was not registering and was making noise when i had it on. the last 2 times i continue to hear noise coming from the car. the noise is heard from underneath and it has to be driven for significant amount of minutes before the noise goes away. i recorded the noise on november 28,2015 and called the dealer very upset because its a problem that's not being addressed and fixed. i dropped the car off on monday november 30,2015 and was told yesterday december 1,2015 that they dont see the problem.this is a new car and i never test driven before buying. i need help. i have the recording but i cant attach it on here.
