Question, I have a 07 Accent with 21,000 mi but I have owned it 2 1/2 yrs. well first the trans acted up today (auto) clunked from rev to drive then seemed to be slipping then ck eng light came on, all this happened out of the blue but they seemed to know of this issue and replaced a sensor. Then they say I need 30,000 mi service now b/c its over 2 yrs old ok, fine then they say drive belts are worn and need to be replaced, $160.00, first are drive belts same as old term for fan belts? and then is 21,000 mi a life span for these belts? I was a bit surprised by that plus the price was a bit shocking also. Anyone have any insight to this, I would appreciate hearing from anyone, Thanks
