OVER CHARGING OF AC SYSTEM,CAUSES TRANSMISSION/TIRES AND ENGINE TO LOCK.THIS IS AN EXTREME HAZARD TO PASSANGERS OF BOTH VEHICLES, AND ANY OTHER ON COMING VEHICLE. PLUS IT CAN BE USED BY DEALERS TO SELL TRANSMISSIONSIONS.IT CAUSES PREMATURE TIRE FAILURE. AND EXTREME LOSS OF CONTROL ON TURNS.IT IS ALSO A HAZARD ON ANY VEHICLES WITH THE SAME SYSTEM.I'VE SPOKEN TO TWO DEALERS AND TWO LOCAL CAR MECHANICS.WHO COULD NOT SOLVE MY PROBLEM.UNTIL THE A/C SYSTEM FAILED,AND THE A/C TECH KNEW WHAT WAS CAUSING THE PROBLEM.MY VEHICLE WOULD STALL HALF WAY THROUGH A TURN(ROUTINELY),ALL FOUR WHEELS (ALL WHEEL DRIVE)WOULD LOCK UP AT 65MPH ON THE INTERSTATE.I'VE NEVER HAD A SET OF TIRES LAST LONGER THAN ABOUT TWENTY THOUSAND MILES. ALL THREE DEALERS MY VEHICLE WAS SERVICED AT SINCE IT WAS NEW, NEVER ADDRESSED THE PROBLEM. *AK
