2001 Mitsubishi Montero Sport

I HAVE A 01' MITSUBISHI MONTERO SPORT XLS 3.0L AS OF THE LAST WEEK IN MARCH I HAD A PROBLEM WITH MY A/C AND CALL AUTO REPAIR SHOP TO MAKE A APPOINTMENT. TO MY SURPRISE THE MITSUBISHI/SATURN SHOP, THE PLACE THAT I HAD TAKEN IT TO 6MTHS TO A YEAR BE4, MY OXYGEN SENSOR TO BE REPLACED AND SOME OTHER THINGS, WAS GONE OUT OF BUSINESS. SO I CALL WHERE I PURCHASED THE VEHICLE FROM, AND WAS TOLD THAT I COULD GOTO A LICENSED MECHANIC SHOP TO GET MY A/C FIXED, OXYGEN SENSOR HAD DEFAULT AGAIN, BUT IT STILL HAD WARRANTY ON IT WITH THE PREVIOUSLY SHOP SO THE RECENT SHOP COULD NOT REPLACE IT AND I ALSO STILL HAD WARRANTY COVERAGE WITH THE CREDIT UNION THAT I PAY MONTHLY PAYMENTS TO. SO I CALLED THE WARRANTY GROUP, AND THE WARRANTY GROUP PAID FOR A/C TO BE FIXED AND I ONLY HAD TO PAY 100 DEDUCTIBLE. I RECEIVED MY SUV BACK ABOUT A WEEK LATER, THEN I NOTICED A KNOCKING WITHIN THE MOTOR SO I WENT BACK TO THE REPAIR SHOP, AND WAS TOLD THAT I NEEDED A OIL CHANGE, BUT I JUST RECENTLY HAD A TUNE-UP AND OIL CHANGE. SO I KNEW THAT I DIDN'T NEED A OIL CHANGE. THE SHOP COULD NOT DETERMINE WHAT CAUSED THE KNOCKING NOISE, BUT ON 5- 23-10 MY SUV HAD MALFUNCTION THIS TIME MY CRANKSHAFT,PULLEY,RODS HAD SEPARATED AND THE ONLY THING THAT WAS HOLDING MY ENGINE TOGETHER WAS THE MAIN BOLT. SO I GOT IT TOWED BACK TO THE REPAIR SHOP AND I HAD TO GET MY ENGINE REPLACED. THE WARRANTY GROUP PAID FOR THE PRE-USED ENGINE, AND I RECEIVED MY SUV BACK ON 6-11-10. I DID NOT DRIVE MY TRUCK NO MORE THEN TO MY HOME AND PARKED IT IN MY YARD, BUT ON THAT TUESDAY JUNE 15, 10 I WENT INTO A FURNITURE STORE FOR ABOUT 20 MINS. AND LEFT MY A/C ON, CAME BACK AND ONLY THE FAN WAS BLOWING, SO I CUT-OFF MY SUV AND WAITED FOR 5MINS. CUT MY SUV BACK ON AND DROVE BACK HOME WITH NO PROBLEMS. I HAD A APPT ON WED. 06-16-10, MY SUV OIL ENGINE LIGHT CAME ON THIS TIME I CHECKED THE OIL AND NO OIL IN THE MOTOR PUT 2QTS BEGIN HOME SPEED DROP75-45RADIATOR BURSTED NEEDENGINE.THE 96-99 RECALL ONMITSUB.
