NHTSA Complaint #11359961 — 2006 JEEP GRAND CHEROKEE

THE PCM IS NOT COMMUNICATING BETWEEN THE COMPUTER AND THE TRANSMISSION. IT'S MAKING THE TRANSMISSION JUMP, LOOSE POWER WHILE DRIVING, WARNING SAYING TRANSMISSION OVER TEMP (CAN COME ON EVEN WHEN YOU JUST START DRIVING), CODE P1603-PCM INTERNAL DUAL PORT RAM, COMMUNICATION FAILURE. THE RPM'S HAVE RAMPED UP AND DOWN WHILE AT A STOP, LOOSE POWER WHILE DRIVING, AND CAN EVEN TURN OFF WHILE DRIVING. EVENTUALLY THE ALTERNATOR WENT BAD. REPLACED ALTERNATOR AND BATTERY HAVE BEEN REPLACED 8/16/20. EVENTUALLY IF THE ECM IS NOT REPLACED THEN IT'LL KILL THE VEHICLE. THE TRANSMISSION OVER TEMP STARTED AROUND 60,000 MILES. THIS ISSUE HAS STEADILY GOTTEN WORSE OVERTIME, BECAME MORE FREQUENT, AND MORE DANGEROUS. I'VE READ OF LOTS OF PEOPLE HAVE THE SAME ISSUE AND THERE'S BEEN NO RECALLS. I FEEL THERE SHOULD BE A RECALL FOR SAFETY ISSUES. PLEASE LOOK INTO THE NUMBER OF PEOPLE HAVING THE SAME ISSUE.
