I AM CURRENTLY HAVING A RE-OCCURING PROBLEM WITH THE STABILITY TRACK. I HAVE HAD IT SERVICED FOUR TIMES NOW TO NO AVAIL. EACH TIME I TAKE IT IN THEY TELL ME IT IS A COMPUTER PROBLEM, AND THAT IT JUST NEED TO BE RESET. I HAVE YET TO HAVE AN ACCIDENT, BUT TODAY I ALMOST DID. WHILE GOING TO THE CURB ENTERING THE FREEWAY THE STEERING WENT CRAZY AND THE SERVICE STABILITY TRACK NOTICE APPEARED. AFTER I ENTERED THE HIGHWAY THE VEHICLE STILL WAS JERKING UNCONTROLABLE. I TURNED OF THE STABILITY TRAC BUTTON IN HOPES OF GAINING CONTROL. THE VEHICLE STILL NOTED THE PROBLEM EVEN AFTER BEING TURNED OFF. I AGAIN HAVE TAKEN TO THE DEALERSHIP IN WOODLAND WHO STATED IT HAD TO BE MY 22" WHEELS. BUT, I FIND THIS HIGHLY UNLIKELY SINCE THE DEALERSHIP ORIGINALLY OFFERED IT TO ME UPON BUYING AND I HAD THIS PROBLEM THREE TIMES BEFORE WITH THE ORIGINAL 17' TIRES. I DO MAINTAIN A RECORD OF ALL SERVICES AND I HAVE A COPY OF WHEN I PURCHASED THE WHEELS, WHICH WAS NOT UNTIL RECENTLY. THIS IS THE SECOND ESCALADE FROM GM THE FIRST ONE WAS DECLARED A LEMON AND THIS ONE APPEARS TO BE TURNING OUT TO BE ONE ALSO.
