AS I WAS DRIVING ON THE FREEWAY WITH THE DRIVER'S SIDE HEATED SEAT ON THE LOW SETTING, I FELT A SUDDEN BURNING SENSATION ON MY BACK OF MY UPPER LEFT THIGH AND SHIFTED SLIGHTLY, PUTTING MY HAND UNDER THE AREA TO SEE WHAT WAS THE MATTER. THE REAR AREA OF THE LEFT SIDE SEAT BOLSTER HAD GOTTEN SO HOT I HAD TO TURN OFF THE SEAT HEATER IMMEDIATELY. I DECIDED NOT TO TURN IT ON AGAIN UNTIL ANOTHER TIME IN LATE MARCH WHEN I AGAIN TURNED ON THE SEAT HEATER. THE SAME SUDDEN FEELING OF "OVERHEATING" WAS IMMEDIATELY FELT IN THE SAME AREA, I TURNED OFF THE SEAT HEATER, AND I HAVEN'T USED IT SINCE THEN. WHEN MY CAR WAS IN FOR SERVICE FOR ANOTHER ISSUE, I MENTIONED IT TO MY SERVICE ADVISOR AND ASKED WHETHER HE KNEW OF OTHER SIMILAR INCIDENTS OR WHETHER THERE WAS A BMW RECALL FOR THE ISSUE. HE SAID NO TO BOTH QUESTIONS. *TR
