my 2009 cube under 30k just past a year. recently I have issue when I ran through uphill or downhill my accelerator didn't responded. next day I went to dealer to check what's wrong with my cube. After noon service adviser called told me that I need to replace transmisson. OMG luckly I still in warranty but, my question are nissan deal should replace with use transmission or brand new? If they replace with use transmission how long they give me a warranty? And anyone have same issue?
