2004 Jeep Grand Cherokee Fuel System Other Electrical System Problems

2004 JEEP CHEROKEE, TWICE NOW THE FUSE TO THE FUEL INJECTOR HAS BLOWN WITHIN A MONTH RENDERING THE CAR UNDRIVABLE. GOING DOWN THE ROAD THE CAR CUTS OFF, YOU CANNOT STEER IT, AND THE BRAKES SEEM NOT TO WORK WELL AT ALL, YOU PRACTICALLY HAVE TO STAND ON THEM. THIS NEARLY GOT ME HIT TODAY GOING THROUGH A RED LIGHT. THE FIRST TIME IT HAPPENED, I WAS GOING DOWN A HILL AND BARELY GOT THE CAR STOPPED BEFORE HITTING A TREE. I HAD IT TOWED TO A MECHANIC, HE CHANGED THE FUSE AND THOUGHT THAT IT WAS OK, UNTIL TODAY. TWO YEARS AGO, THE WIRING TO THE WINDOWS AND DOOR LOCKS QUIT WORKING AND HAD TO PAY TO HAVE THAT REPLACED, THERE IS DEFINITELY SOMETHING NOT RIGHT WITH THESE VEHICLES. YEARS AGO, I HAD AN ACCELERATION PROBLEM, GOT STUCK, FINALLY GOT CONTROL OF IT, AND THE CHECK ENGINE LIGHT STAYED ON, TOOK IT TO THE DEALERSHIP, THEY SAID THEY COULDN'T FIND ANYTHING WRONG, NEVER COULD TELL ME WHY THE CHECK ENGINE LIGHT HAD COME ON AFTER THIS OCCURRING. *TR
