This is a finance vehicle saw the 2004 Nissan Titan really like it for the work that I do and my husband agreed to partially financed it. The first driving off the car lot the service engine light came on when we got home I called back the dealer to let him what had happened, he said to bring it back the following Thursday to see what was going on, during the same week the two front windows fell down into the slot couldn't come back up so we had drive in the dead of winter with the windows done. Finally we drop the pickup off at the dealer, it was there for 2 full weeks before we got it back, thinking everything was fixed . A few days after the engine light came back on we called them again they in replied telling us they can't do anything about the problem because the vehicle is a used vehicle. Oh my god. Now I have put over a $1000 in parts and now the mechanics are telling me it needs a new engine. Please I need help because I have to be paying the finance company for something I cant use.
