WHILE RIDING IN THE PASSENGER SEAT OF A 2006 CHEVROLET HER FOR A PERIOD OF ABOUT 2 HOURS I RECEIVED 2ND DEGREE BURNS TO POSTERIOR. CHECK OF THE SEAT BY CHEVY DEALER THE NEXT WEEK REPORTED NO PROBLEM WITH THE SEAT HEATER. IT HAS BEEN A MONTH AND I AM STILL RECOVERING FROM THE BURNS AND HAVE HAD MEDICAL TREATMENT TWICE WEEKLY . I HAVE RIDDING OVER 25,000 MILES (MOSTLY IN THE DRIVERS SEAT) AND THE SEAT HEATERS HAVE BEEN ON THE BIGGEST PART OF THE TIME OVER THE PAST YEAR. BUT THIS TWO HOUR STINT CAUSED ME SEVERE BURNS. *NM
