2004 NISSAN FRONTIER Fuelpropulsion System Problems

THIS TRUCK HAS BEEN WORKED ON MULTIPLE TIMES FOR RUST, CORROSION, GAS TANK LEAKS, BEARINGS AND REAR DIFFERENTIAL. IT CONTINUES TO RUST AND CORRODE. THE MOTOR RUNS WELL BUT THE VEHICLE HAS RUSTED EVEN WITH EXCELLENT CARE. I AM SO DISAPPOINTED. THE GAS TANK HAS BEEN FIXED MULTIPLE TIMES AND CONTINUES TO CORRODE AND LEAK. I THINK THAT ALL OF THESE ISSUES NEED TO BE CHECKED ON. THE REAR DIFFERENTIAL HAS CORRODED AND ALL OF THESE ISSUES ARE VERY EXPENSIVE EVERY TIME THAT IT HAS TO BE FIXED. I WOULD APPRECIATE YOUR HELP WITH THESE PROBLEMS.

TRUCK TOTAL MILEAGE IS ONLY 55,000 AS IT IS NOT USED VERY MUCH. 3 ISSUES OCCURRED APPROX. AT 49,000MILES. 1) ENGINE STARTED TO MISS. UPON CHECKING SPARK PLUGS IT WAS DISCOVERED THAT THE PLUG CAVITIES IN THE HEAD WERE FULL OF OIL. THE VALVE COVER GASKET SEALS HAD LEAKED AND THE OIL FILLED SPARK PLUG HOLES CAUSED IT TO MISS. THIS IS NOT COVERED UNDER WARRANTY SO REPAIRS WERE DONE AT MY COST. HAD TO REPLACE ALL OF THE TOP END VALVE COVER GASKET AND SPARK PLUG HOLE SEALS AS WELL AS THE CAM END SEALS. 2) ONE DAY I GOT INTO THE TRUCK AND WHEN I STARTED IT UP AND PRESSED THE BRAKES THE PEDAL WENT TO THE FLOOR. UPON CHECKING THE BRAKE MASTER CYLINDER RESERVOIR IT WAS EMPTY. FOUND THAT THE REAR AXLE BRAKE LINE HAD RUSTED THROUGH AND HAD BURST SPRAYING BRAKE FLUID ALL OVER THE SPARE...
