MY "STABILITRAK OFF", "TRACTION CONTROL OFF", ABS LIGHT, CHECK ENGINE LIGHT ALL CAME ON. MY SPEEDOMETER AND OTHER GAUGES STARTED SWINGING FROM LEFT TO RIGHT AND THEN FLATLINING, MY POWER LOCKS, "LOCKED AND UNLOCKED" ON THEIR OWN. THIS HAPPENED REPETITIVELY AS I WAS DRIVING. I HAVE OWNED MY 2007 CHEVY TAHOE FOR 18 MONTHS AND THIS HAS OCCURRED 4-5 TIMES, TWICE IN THE FIRST 12 MONTHS. I HAVE TAKEN TO A CHEVY DEALER TWICE TO DIAGNOSE AND REPAIR THE PROBLEM BUT THEY HAVEN'T BEEN ABLE TO DIAGNOSE PROBLEM. *TR

TIRES:TEMPORARY/EMERGENCY SPARE TIRE
GM/CHEVROLET CUSTOMER SERVICE WILL NOT CORRECT SAFETY ISSUE WITH SPARE TIRE. GM/CHEVROLET CUSTOMER SERVICE WILL NOT PUT RESPONSE IN WRITING. GM/CHEVROLET CUSTOMER SERVICE WILL NOT DISCUSS MIXING OF BRIDGESTONE AND GOODYEAR BELT DESIGNS. THE SPARE IS NOT A "DUMMY TIRE" AND IS NOT A "FULLY OPERATIONAL SPARE" PER GM. THE SPARE CANNOT BE USED IN 4WD, IF SPARE USED IN 4WD WARRANTY IS VOIDED. GM/CHEVROLET MIXES TIRE MFG, TIRE DESIGN, TIRE # BELTS ON DRIVE TIRES AND "SPARE". THIS IS AN UNSAFE ACT. THE FOUR DRIVE TIRES ARE BRIDGESTONE DUELLER HL ALENZA P275-55R20 (2POLY/2STEEL/1NYLON BELT). THE SPARE TIRE IS A GOODYEAR WRANGLER HP P265-70R17 (2POLY/2STEEL BELT) (MFG DESIGN IS FULLY OPERATIONAL) SPARE. GM/CHEVROLET HAD NO DISCLOSURE ABOUT THE ODD SPARE CATEGORY PRIOR TO PURCHASE AND NOT NOTED IN WINDOW STICKER. OWNER MANUAL IS UNCLEAR ABOUT THE SPARE AND AVOIDS ANY FACTS ABOUT THE SPARE BEING GOODYEAR AND DRIVE TIRES ARE BRIDGESTONE DESIGN. GM/CHEVROLET HAS CREATED A THIRD CATEGORY FOR A SPARE: "BOBO". TYPE 1 IS FULLY OPERATIONAL SPARE, TYPE 2 IS A DUMMY SPARE (NOT FULLY OPERATION), AND TYPE 3 IS NEW AND IS A BOBO SPARE, APPEARS TO BE A FULLY OPERATIONAL TIRE BUT GM STATES NOT FULLY OPERATIONAL (AND NOT A DUMMY TIRE TOO). THERE IS ABSOLUTELY NO REASON FOR GM TO NOT HAVE A BRIDGESTONE DUELLER HL ALENZA P265-70R17 TIRE ON THE SPARE RIM, INSTEAD OF A GOODYEAR WRANGLER HPP265-70R17 TIRE. THIS WOULD MAKE ALL TIRES ON THE TAHOE BRIDGESTONE DUELLER HL ALENZA DESIGN/BELTS. *TR
