2004 GMC YUKON DENALI Engine Problems

DRIVING VEHICLE AT 30 MPH. LOST ALL POWER AND ENGINE. NO BRAKES, NO POWER STEERING, NO DASH LIGHTS, ENGINE QUIT RUNNING, NO EXTERIOR LIGHTS. PARKED VEHICLE IN PARKING LOT. NO POWER AT ALL. AFTER ABOUT 20 MINUTES OF WAITING VEHICLE STARTED AGAIN AND HAD MINIMAL ACCELERATION/POWER. *TR

UPON START UP OF VEHICLE, A TICKING NOISE WAS HEARD FROM THE ENGINE COMPARTMENT. UPON INSPECTION, FOUND THAT THE LEFT REAR EXHAUST BOLT ON THE EXHAUST MANIFOLD HAD BROKEN OFF CAUSING EXHAUST LEAK. UPON INVESTIGATION ON THE INTERNET, THIS IS A VERY COMMON ISSUE WITH THE GM 6.0 LITER AND OTHER ENGINES. THIS IS A SERIOUS SAFETY DEFECT AND ALSO CAUSES THE EMISSIONS CONTROLS OF THE ENGINE TO BE INOPERABLE. POSSIBLE SAFETY ISSUES CAN AND DO INCLUDE; CARBON MONOXIDE POISONING AND THE POSSIBILITY OF ENGINE COMPARTMENT FAILURE. *TR

BROKEN EXHAUST BOLTS ON GM ENGINES. THIS IS A WELL KNOWN DEFECT AND FAILURE ON THESE ENGINES AND IS PART OF THE VEHICLE EMISSIONS SYSTEMS. THIS IS ALSO A VERY SERIOUS SAFETY DEFECT, POSSIBLE ISSUES WITH THIS FAILURE INCLUDE; CARBON MONOXIDE POISONING AND ENGINE COMPARTMENT FIRE. *TR

THE "STABILITY CONTROL DISABLED" SENSOR COMES ON FOLLOWED BY "REDUCED ENGINE POWER" AND MY VEHICLE WON'T GO FASTER THAN 5MPH. THIS HAS HAPPENED AT LEAST 6 TIMES IN THE PAST SEVERAL MONTHS ONLY UPON START UP OF THE VEHICLE. SOMETIMES, IF I WAIT A COUPLE OF MINUTES AND RESTART MY CAR, IT'LL START JUST FINE BUT THE CHECK ENGINE LIGHT COMES ON. I FIRST BROUGHT IT INTO HENDRICK CHEVROLET ON 10/15/12. THEY CHARGED ME ALMOST $700 TO REPLACE "APP SENSOR ASSEMBLY". THEN I BROUGHT IT IN AGAIN ON 11/6/12 FOR THE SAME ISSUE. THEY REPLACED THE "CONNECTOR AT THE THROTTLE BODY" AND CHARGED ME $223.09. THE ISSUE TEMPORARILY WENT AWAY. I THEN BROUGHT IT BACK ON 12/20/12 WITH THE SAME ISSUE BUT THIS TIME THE CHECK ENGINE WON'T TURN OFF AS A RESULT OF THE REDUCED ENGINE POWER-STABILITY CONTROL DISABLED WARNING. THEY SIMPLY RESET THE WARNING AND THAT WAS IT....

WHILE DRIVING ON INTERSTATE TRACTION CONTROL LITE CAME ON IN DASH THEN POWER TO SUV WAS LOST THEN ELECTRONIC MESSAGE READ OUT STATED "STABILITY CONTROL DISABLED " THEN " REDUCED ENGINE SPEED" MESSAGE APPEARED. I WAS ABLE TO PULL OFF INTERSTATE BUT NEARLY GOT REARENDED HIT BY SEMI. ENGINE WOULD RUN ONLY AT IDLE SPEED. AFTER SHUTTING OFF VEHICLE AND WAITING MINUTE OR TWO THEN RESTARTING IT RAN FINE. THIS HAS HAPPENED NUMEROUS TIMES SINCE THEN. SPEEDS VARY 70,55,40 MPH IT DOESN'T MATTER. AFTER CALLING DIFFERENT GMC DEALERS ABOUT PROBLEM THEY ACT LIKE THIS IS SOMETHING THEY NEVER HEARD OF."BULL**** !!!!. ITS THE SAME PROBLEM NUMEROUS GMC OWNERS ARE FACING ON THE INTERNET. GMC CUSTOMERS HAVE SPENT THOUSANDS OF DOLLARS WITH NO PROBLEMS SOLVED. ALL THEY WANT TO DO IS HOOK YOU UP TO ELECTRONIC MACHINE AND OVERCHARGE YOU FOR THE SAME THING AUTOZONE ,ETC. BUSINESSES WILL DO FOR FREE....

WHILE IN THE MIDDLE OF DRIVING, THE "STABILITY CONTROL DISABLED" SENSOR COMES ON FOLLOWED BY "REDUCED ENGINE POWER" AND MY VEHICLE JUST SHUTS OFF. I HAVE BEEN FORTUNATE THE 4-5 TIMES IT HAS HAPPENED AS I HAVE BEEN ABLE TO PULL OFF THE ROAD, WAIT A COUPLE OF MINUTES AND RESTART MY CAR. I HAVE ALREADY REPLACED A HUB THAT MY MECHANIC SAID WAS CAUSING A "TRACTION CONTROL" PROBLEM FROM EARLIER. I AM READING ONLINE ALL OF THE NIGHTMARES AND I UNFORTUNATELY DO NOT HAVE THOUSANDS OF DOLLARS TO KEEP TRYING TO FIX AN ISSUE THAT GMC IS CLEARLY AWARE OF. I HAVE 5 KIDS AND FREQUENTLY DRIVE THEM AROUND AND SOMEONE IS GOING TO GET HURT AND I THINK GMC SHOULD TAKE SOME RESPONSIBILITY. *TR
