It is just like the the service bulletin out for the 2006 and later gmc sierra except it’s for a 2004 gmc Yukon slt 4x4 4.8L. It is going into reduced engine power mode and it has to do with the throttle actuator control module. Throws code P2108

My kids and I was on the interstate and all of sudden my yukon reduce engine power.Dropping to 30 in a speed zone of 70.I was very afraid for our safety and appreciate there concerns for reducing engine power to save the truck,but that's very dangerous. So I paid to replace the throttle body and gas pedal cause that was the codes for the problem. But it's still doing the same thing and I don't have money to keep buying parts.Plus it a gm problem and I really need some help with the fixture..

ENGINE LOSING COOLANT, WITH NO APPARENT SIGNS OF LEAKAGE. COOLANT APPEARS TO BE LEAKING INTO THE ENGINE OIL, CAUSING IT TO SLUDGE, THEREBY CAUSING ENGINE FAILURE. GM IS AWARE OF AN ISSUE AND ISSUED TSB 06-06-01-019B FOR DEFECTIVE CYLINDER HEAD CASTING. I BOUGHT THIS CAR USED LAST YEAR AND NOW OWE 10000 FOR A CAR THAT NEEDS A 6000 ENGINE REPLACEMENT. GM SHOULD BE MADE ACCOUNTABLE FOR THIS SINCE THEY ARE WELL AWARE OF THE ISSUE, PER THEIR OWN DIRECTIVE.

SINCE GETTING THIS CAR IN 2005, MY HUSBAND AND I HAVE EXPERIENCED REDUCED ENGINE POWER. WHETHER GOING 40MPH ON A 2 LANE ROAD OR 70 ON THE INTERSTATE, THIS CONTINUES TO HAPPEN. WE HAVE HAD THIS ISSUE "FIXED" TWICE, SPENT ABOUT $1000 ON 2 SEPARATE "REPAIRS," YET THE PROBLEM PERSISTS. I CANNOT TELL YOU HOW SCARY IT IS TO BE GOING WITH THE FLOW OF TRAFFIC AND THEN HAVE YOUR ENGINE POWER REDUCED. TO BE GOING 70 AND THEN FORCED BELOW 70 IS DANGEROUS. WE COULD HAVE BEEN HIT AND KILLED TRYING TO ACCELERATE AND PASS SOMEONE. THIS ACTUALLY HAPPENED. I KNOW NUMEROUS GM OWNERS HAVE HAD THIS PROBLEM ACROSS NUMEROUS VEHICLES. WHY HAVEN'T YOU FORCED THEM TO FIX IT? IS IT BECAUSE THE GOVERNMENT BAILED THEM OUT, AND IT WOULD BE DETRIMENTAL TO THE ECONOMY? SAFETY AND RELIABILITY ON ROADWAYS SHOULD BE IMPORTANT, TOO.

MY CAR BEGAN TO HAVE A BUILD UP OF SLUGS AND BEGAN LOOSING OIL PRESSURE AND COOLANT AND NEEDED OIL ADDED AND COOLANT FREQUENTLY. OIL PRESSURE FLAT-LINED IN JANUARY OF 2012 AND IT WAS TAKEN TO MY MECHANIC. THE SLUGS WERE CLEANED AND A NEW OIL PUMP WAS PLACED BECAUSE OF THE BUILD UP OF SLUGS. I WAS ADVISED TO CHANGE THE OIL FREQUENTLY TO CLEAN THE SLUG OUT BUT IT CONTINUED TO BUILD UP AND THE MYSTERY OF LOOSING COOLANT OIL PRESSURE HAS BOTTOMED OUT TWO MORE TIMES AND I FOUND A ARTICLE ON THE INTERNET THAT A NUMBER OF GMC VEHICLES INCLUDING MINE WERE BUILT WITH DEFECTIVE CYLINDER HEADS DUE TO CRACKS OVER TIME WHICH ALLOWS COOLANT TO LEAK INTO ENGINE AND MIX WITH THE OIL WHICH BUILDS UP SLUG. I WANT TO KNOW WHY A RECALL DOES NOT EXIST. THIS HAS COST ME SEVERAL THOUSANDS OF DOLLARS....I NEED GMC TO MAN UP TO THE PROBLEM AND FIX IT.

TODAY WHEN STARTING MY 2004 YUKON, THE INFORMATION CENTER DISPLAYED THE MESSAGES: "STABILITY CONTROL DISABLED", "ENGINE POWER REDUCED". AND THE VEHICLE WOULD NOT GO OVER 20 MPH ON A LEVEL SURFACE AND BARELY 3 MPH UP A MODERATELY STEEP HILL. I HAD TO PULL OVER ON ROUTE 80, DRIVE ON THE SHOULDER AND THANKFULLY MADE IT TO A DEALER. I'VE HEARD OF SO MANY GMC VEHICLES HAVING THIS SAME ISSUE. WE NEED A SOLUTION BEFORE SOMEONE GETS KILLED!

ENGINE AND ENGINE COOLING

WE HAVE A 2004 GMC YUKON. SINCE WE'VE HAD IT, REDUCED ENGINE POWER HAS BECOME A CONSTANT AND DANGEROUS PROBLEM. MOST RECENTLY, YESTERDAY, MY HUSBAND WAS TRYING TO ACCELERATE TO PASS A SLOWER VEHICLE WITH HUGE TIRES ON THE BACK ONLY TO HAVE THIS HAPPEN. IF SOMEONE HAD BEEN BEHIND US, WE WOULD HAVE BEEN HIT, SERIOUSLY INJURED, MAYBE EVEN DEAD WITH SOME OF THE CIRCUMSTANCES WE HAVE HAD ON THE INTERSTATE. TODAY IS AUGUST 23, 2011. WE HAD THIS VEHICLE FIXED ON JULY 28, 2011, PAYING ALMOST $600 FOR IT TO BE TAKEN CARE OF. IT SAYS ON THE TICKET THAT WE TOLD THEM ABOUT IT AND WERE UNDER THE IMPRESSION THIS WOULD TAKE CARE OF IT. THEY REPLACED THE ACCELERATOR PEDAL ASSEMBLY, WHICH I BELIEVE INCLUDED THE APP SENSOR, AND CLEANED THE THROTTLE BODY OF EXCESSIVE CARBON BUILD UP. AFTER SPENDING $500-600, I WANT TO KNOW WHY WE ARE STILL HAVING THIS PROBLEM ALONG WITH SO MANY OTHERS I HAVE SEEN COMPLAIN ABOUT IT ONLINE? GMC HAS A KNOWN PROBLEM THAT NEEDS TO BE RESOLVED.

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.

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.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

THE PROBLEM I'M HAVING IS A HORRIBLE BUBBLING OR GARGLING SOUND EMMITING FROM MY 2004 YUKON EXHAUST. IT SOUNDS REALLY BAD, ENOUGH TO TURN PEOPLES HEADS WHILE I'M SITTING AT THE CONVENEIENCE STORE OR A DRIVE THRU. THE DEALER IN WHICH I BOUGHT IT FROM STATES THAT THEY ALL MAKE THIS SOUND, BUT I'M NOT STUPID. I KNOW OTHERS WITH THE SAME MAKE AND YEAR MODEL AND THEY DO NOT HAVE THIS PROBLEM. I JUST WANT IT FIXED. IF I'M WILLING TO PAY $44,000 FOR A VEHICLE I EXPECT IT TO LOOK AND SOUND GREAT OR AT LEAST LOOK AND SOUND LIKE A NEW ONE. PLEASE HELP!

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

WHEN MY 2004 GMC YUKON WARMS UP, A LOUD REPETITIVE CLANGING NOISE EMINATES FROM THE EXHAUST SYSTEM. THIS CAN BE HEARD WHILE DRIVING AND CONTINUES FOR A PERIOD AFTER THE VEHICLE IS TURNED OFF. THE YUKON WAS PURCHASED NEW ON 5/31/04 AND BEGAN MAKING THE NOISE WITHIN 500 MILES. GMC SAYS ENGINEERING HAS BEEN WORKING ON THE PROBLEM SINCE 11/03 AND IT INVOLVES METAL IN THE EXHAUST SYSTEM BEING DEFORMED BY THE HEAT. I HAVE SPOKEN WITH SEVERAL OTHER YUKON OWNERS AND MADE A POINT TO LISTEN TO OTHER YUKONS ON THE ROAD AND HAVE NOT FOUND ANOTHER YUKON EXHIBITING THE SAME PROBLEM. GMC REFUSES TO REPLACE THE EXHAUST SYSTEM. IF THE METAL IS DEFORMED, HOW DO I KNOW THAT IT IS NOT LEAKING FUMES INTO THE PASSENGER COMPARTMENT?
