I bought a brand new loaded XR on Friday night and during my first drive, it died right in the middle of the highway. Had it towed to the dealer who thinks both the main computer (they couldn't even get diagnostics from it) and the transmission will need to be replaced. I was told this could take 2-3 weeks so I'll have to rent a car during that time because my trade is already gone. Should I request a brand new one or let this one be fixed?
