NHTSA Complaint #10789392 — 2006 JEEP GRAND CHEROKEE

I BOUGHT MY VEHICAL USED IN JUNE. (2006 JEEP GRAND CHEROKEE LIMITED WITH 160,000 MILES) I TOOK IT BACK TO DEALER WHERE THEY TOLD ME THE BATTERY HAD ISSUES AND THEY "FIXED" THE PROBLEM. I'D BE DRIVING AND IF I CAME TO A STOP I WOULD LOSE ALL POWER AND MY ENGINE WOULD TURN OFF. AT A DRIVE THROUGH, IT WOULD DIE, AT A STOP LIGHT, DIE. IN OCTOBER MY ISSUES STARTED UP AGAIN. NOW THE SAME THINGS ARE HAPPENING BUT EVERY LIGHT ON THE DASH LIGHTS UP, FLASHES/FLUTTER/FLICKERS, HEADLIGHTS SHUT OFF, RADIO SHUTS OFF, HVAC SYSTEM SHUTS OFF, BUT ENGINE WILL RUN FOR ABOUT 20MIN THEN I LOSE ALL POWER WHERE EVER I AM, I'LL BE DRIVING DOWN THE HIGHWAY GOING 55MPH AND THE ENGINE SHUTS OFF. PULLING INTO THE STORE ENGINE SHUTS OFF. ON MY WAY TO WORK ENGINE JUST SHUT OFF WHILE GOING DOWN THE HIGHWAY. COASTED AS FAR AS I COULD TO GET TO A SAFE PLACE TO STOP. NOW IT WON'T START AGAIN.
