2004 GMC Yukon Denali Xl

STABILITY CONTROL DISABLED COMES ON WITH ENGINE POWER REDUCED. THIS HAPPENED AS I AS DRIVING IN THE HIGHWAY. SPEED DRASTICALLY REDUCED FORM 65 TO 10 MPH. I COULD HAVE BEEN KILLED. GM IS AWARE OF THIS PROBLEM AND WILL NOT ACT UNTIL THERE'S A FATALITY BECAUSE OF THIS ISSUE. THIS IS CRIMINAL. NHTSA HAS RECEIVED NUMEROUS COMPLAINTS REGARDING THIS ISSUE AND HAS NOT ACTED.

TL* THE CONTACT OWNS A 2004 GMC YUKON DENALI XL. WHILE DRIVING APPROXIMATELY 60 MPH, THE VEHICLE STALLED. AFTER SEVERAL ATTEMPTS, THE VEHICLE RESTARTED. THE FAILURE RECURRED NUMEROUS TIMES INTERMITTENTLY. THE VEHICLE WAS TAKEN TO A DEALER FOR DIAGNOSTIC TESTING. THE MECHANIC REPLACED THE TAC MODULE AND ELECTRONIC THROTTLE BODY, BUT THE FAILURE RECURRED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 120,000.

VEHICLE STARTED FINE, THEN AS I WAS DRIVING IN NEIGHBORHOOD ENGINE SHUT OFF AND I LOST ALL POWER, COULD NOT TURN CAR WITHOUT STEERING AND CRASHED INTO CURB UP THE STREET, CAR WOULD NOT START, HAD AAA COME TOW TO OUR HOME. HAD A NEW BATTERY, AND WOULD ONLY TAKE A CHARGE WHEN BYPASSING BATTERY DIRECTLY INTO ENGINE. NOW SOMETHING IS DRAINING BATTERY AND IF I DON'T START AND RUN EVERY TWO DAYS , BATTERY DEAD. ELECTRICAL CLUSTER ALSO GOING BAD AND INSTRUMENTS NOT WORKING, AIR CONDITIONING ELECTRICAL PROBLEM , WILL BLOW COLD OUT OF ALL BUT TWO VENTS, WHERE IT BLOWS 90 DEGREES. BACK WINDOW WIPER STOPPED WORKING, ALL ELECTRICAL RELATED. DEALER SAID NO ERROR CODES TEST DROVE FOR A WEEK TO GET TO REPRODUCE STALL DRIVING, RETURNED TO ME SAYING CAN'T DIAGNOSE. SO FRUSTRATING AND DANGEROUS.

HELLO OVER THE LAST TWO WEEKS, MY TRUCK HAS HAD THE FOLLOWING INTERMITTENT MESSAGE FLASH ACROSS THE DASH "REDUCED ENGINE POWER" AND "STABILITY SYSTEM DISABLED", AND THE TRUCK IS LIMITED TO 25MPH.. THIS HAS HAPPENED NUMEROUS TIMES IN TRAFFIC, FORCING MY WIFE, OR MYSELF TO HAVE TO TURN ON THE HAZARD LIGHTS AND PULL OFF THE FREEWAY AS QUICKLY AS POSSIBLE. AFTER SITTING FOR 5-10 MINUTES THE LIGHTS WILL GO OFF, AND THE ENGINE WILL BE FINE. THE DESCRIBED SCENARIO JUST OCCURRED AGAIN TODAY FOR THE 3RD TIME IN ONE DAY,, SO THINGS APPEAR TO DEGRADING RAPIDLY, AND I WILL NEED TO HAVE THE SYSTEM REVIEWED AT THE LOCAL DEALERSHIP. I AM VERY CONCERNED AS I HAVE FOUND A THREAD WITH NUMEROUS RELATED CONCERNS AT EDMUNDS,COM (HTTP://FORUMS.EDMUNDS.COM/DISCUSSION/5759/GMC/YUKON-DENALI/GMC-YUKON-REDUCED-ENGINE-POWER-MESSAGE), AND IT DOES NOT APPEAR THAT THEIR IS A VALID RECALL FOR MY VIN. I AM NOT CLEAR WHAT MAY BECOME OF THIS COMPLAINT, BUT I AM VERY CONCERNED THAT MY WIFE MAY BE IN A VERY DANGEROUS SITUATION IF THE ENGINES KEEPS REDUCING POWER WHILE DRIVING ON THE FREEWAY. THANK YOU FOR YOUR TIME. *TR
