Engine Oil Leaking problems of the 2003 Nissan Murano

My car was running sluggish and low power when turned on lights, when tested battery it was fine but voltage low so I guess its not charging battery. Doesnt start alot of times. Engine runs hot quick, put new battery did same and one day the battery and brake light stayed on and then while driving it just stopped like I was giving it gas but car wasnt moving. Now it wont start at all. There may be a tiny oil leak but dont know from where and it drives rough but they say my shocks and struts and suspension and everything is ok.

My Nissan Murano was a brand new 2003 it is now 8 years old with 46015 miles. The Nissan service department in nh cared for my vehicle regularly; my first problem occurred when the engine started sending out black smoke, I fought for Nissan to take responsibility for what was happening to my vehicle, they did; it took six to eight weeks to get the oil smell flushed out of the air conditioner. I understand wear and tear but, major engine faults happening so soon; Nissan claims being the top vehicle manufactures. One of the many reasons I bought their brand. I did everything they said to keep my vehicle functioning; then it happened again; the rear powertrain reached its end, and oil leaking in the engine, the piston ball bearings is broken; and now the oil is leaking out. The average miles driven per year is 12000; my vehicle average 1500-miles yearly. I cannot nor will I battle over the 60 months/100,000 miles warranty contract; I am appealing to Nissan corporation saying, look and see in my case my vehicles? problems are unique; see the oddness of an engine with only 46015 miles having such major problems. See my maintenance records, it was not due to neglect, look at the first time I had a major problem with this engine very early in the first two years of owning it. The engine and components are faulty; I just got a bad make. A feedback card came in my mail it says, ?as a valued Nissan customer, your satisfaction throughout your ownership experience is our company?s highest priority?? so, then why hide behind the expired warranty? I was told, even if the NHTSA force a recall and Nissan found I am the cause, the Nissan board would willfully recall vehicles from 2004 up, to spite me or, single out the specific problems I now have repair them ignoring the vehicle?s young engine is completely faulty.

The contact owns a 2003 Nissan Murano. The contact stated the rear differential of the vehicle failed and oil was leaking into the engine. The vehicle was taken to the dealer and the contact was told that the rear differential was worn. The dealer also stated that the oil leak caused the pistons to become dry, which were destroyed. The dealer advised the contact that the pistons and the differential needed to be replaced. The failure mileage was 5,000 and the current mileage was 46,015.
