SHORTLY AFTER PURCHASING THE VEHICLE, ELECTRICAL SYSTEM AND ON-BOARD COMPUTER ISSUES STARTED OCCURRING: TIRE MONITOR SYSTEM (TPMS) IN-OP. WARNINGS RANDOMLY APPEARING IN DASH: CHECK TIRE MONITOR SYSTEM. CHECK LEFT/RIGHT REAR TIRE PRESSURE. TPMS DID NOT WARN OF A FLAT TIRE EVEN THOUGH A SIGNIFICANT AMOUNT OF AIR WAS LOST. INCREASING NO. OF ISSUES WITH ELECTRICAL SYSTEM: KEYLESS ENTRY FAILS. CHECK AIRBAG WARNING APPEARS. CHECK A/C WARNING IN DASH. AMBIENT TEMPERATURE GAUGE ERRATIC. COMPASS SHOWING N (OR NE/NW BUT ALWAYS INCORRECT HEADING). CRUISE CONTROL WILL NOT RESUME AT TIMES OR SET INCORRECT SPEED (A FEW M/H HIGHER OR LOWER). SPEED HAS INCREASED ON ITS OWN. ONCE, I NOTICED THE SPEED AT OVER 80M/H WHEN I HAD SET THE CRUISE CONTROL AT 70. DASH DISPLAYING WARNINGS QUICKLY AND YELLOW WARNING LIGHTS FLASH BRIEFLY, WHICH IS EXTREMELY DISTRACTING AND WARNINGS CANNOT BE READ. TPMS LIGHT COMES ON ROUTINELY AFTER DRIVING FOR 1-3 HOURS. WARNINGS MAY FLASH AT ANY TIME. TOOK THE VEHICLE IN SIX TIMES AT THE REQUEST OF GM. SOME PARTS WERE REPLACED BUT ELECTRICAL ISSUES KEEP INCREASING AND ORIGINAL ISSUES CANNOT BE FIXED. KEYLESS ENTRY WORKING FOR NOW, AFTER COMPONENTS WERE REPLACED TWICE. E-BRAKE DID NOT WORK WHEN THE VEHICLE WAS PURCHASED. THOUGH PROMISED BY DELIVERY, CAR HAD TO BE TAKEN IN FIVE TIMES FOR E-BRAKE TO WORK MODESTLY. I AM NOT IN POSSESSION OF ANY OLD PARTS AS REPAIRS WERE PERFORMED UNDER WARRANTY. *TR
