MULTIPLE SERVICE VISITS WITH COMPLAINTS RE BRAKES NOT WORKING FULLY, FUEL GAUGE WAS ALWAYS INCORRECT, PASSENGER AIR BAG NOT WORKING. AIR BAG SENSOR WAS REPLACED BUT DID NOT CORRECT THE PROBLEM. AFTER MULTIPLE COMPLAINTS REGARDING FUEL GAUGE AND SEVERAL ATTEMPTS TO REPAIR, WAS TOLD NO PROBLEM FOUND. *AK STBILITY SENSOR REPLACED WHILE GOING THRU PARKING LOT AT 15 MPH, SLIGHTLY TOUCHING THE BRAKES, THE CARS STABILITY SYSTEM LIGHT CAME ON AND THE BRAKES FAILED. CAR DID HARD RIGHT, BRAKES FAILED AND CAR RAN OVER CURB AND INTO SIGN. GM FINALLY REPURCHSED THE VEHICLE AFTER SEVERAL MISCOMMUNICATIONS RE THE TERMS OF REPURCHASE BUT REFUSED TO COVER THE DAMAGE TO THE SIGN AND EXPECTED ME TO REPAIR THE CAR BEFORE THEY WOULD PURCHASE
