ONE SIDE OF ENGINE BLOCK IS BURNING OUT ALL 4 SPARK PLUGS; NEED DIAGNOSTIC INFORMATION SENT TO OUR MECHANIC SO HE CAN FIX THIS PROBLEM. NO RESPONSE. ENGINE LIGHT IS ON. TOTAL MILEAGE ON 2004 YUKON LL PURCHASED FROM DAVE SMITH AUTO, KELLOG IDAHO IN NOV OF 2004 IS 1,292. YES, THIS IS CORRECT. ONE THOUSAND TWO HUNDRED AND NINETY TWO MILES! I WOULD THINK GMC OR DAVE SMITH WOULD BE INTERESTED IN FIXING THIS PROBLEM ESPECIALLY WITH A NEW VEHICLE. WAITING FOR THEM TO REPLY TO WARRANTY WORK. WE ARE A REMOTE SITE WOMEN'S SHELTER. WE NEED A VEHICLE THAT RUNS! *JB

POWER TRAIN
THE VEHICLE SUDDENLY LOST POWER AND THE STABILI-TRAC SYSTEM WARNING APPEARED IN THE DIC, THEN THE TRACTION CONTROL SYSTEM WARNING APPEARED IN THE DIC, THEN ENGINE POWER REDUCED BY 16% IN THE DIC. DROVE VEHICLE TO EXIT RAMP AND TURNED ENGINE OFF. VEHICLE RESTARTED WITH ONLY THE CHECK ENGINE LIGHT ON AND NO WARNINGS IN THE DIC. THE ENGINE DID NOT HOWEVER RUN SMOOTHLY. I TOOK IT TO A DEALER WHO CLEAR SOME CODES AND REPLACED THE TPS. CHECKED ALL FUSES. NO FURTHER PROBLEM. HOWEVER A FRIEND HAS THE SAME VEHICLE IN A 2010 MODEL. SAME PROBLEM DEALER REPLACED A THROTTLE BODY. CHECK OUT THE GM FORUM AT HTTP://TOWNHALL-TALK.EDMUNDS.COM/DIRECT/VIEW/.F0E807E/0 THIS FORUM SHOWS LITERALLY HUNDREDS OF COMPLAINTS ABOUT THE SAME PROBLEM AND IN SOME CASES CAUSING ACCIDENTS. MY VEHICLE WAS REPAIRED ON 1-24-2013, AND SO FAR IT APPEARS THAT MY PROBLEM HAS BEEN RESOLVED, HOWEVER IT APPEARS GM IS NOT REALLY FIXING THE PROBLEM. I AM CONCERNED ABOUT THIS FOR THE NEXT OUT OF TOWN TRIP I TAKE. *TR
