2006 GMC YUKON Engine Problems

MY VEHICLE WAS IN MOTION DRIVING ON THE FREEWAY AT 70 MPH WHEN ALL OF THE SUDDEN MY CAR LOST POWER TO 30 MPH ALL THE WAY DOWN TO 5 MPH.I PRESSED ON THE ACCELERATOR TRYING TO GAIN SPEED WITHOUT SUCCESS THE CAR DID NOT ACCELERATE MORE THAN 30 MPH, NO MATTER HOW MUCH I PRESSED ON THE ACCELERATOR. WHEN I LOOKED DOWN AT THE DASHBOARD I SAW TWO WARNING LIGHTS GO OFF "STABILITY SYS DISABLED" FOLLOWED BY "REDUCED ENGINE POWER" LUCKILY I WAS ABLE TO MOVE TO SAFETY. THE ROAD WAS DRY AND NO BUMPS TO DISABLE STABILITY. THE TRACTION CONTROL IN THIS VEHICLE IS LOCATED FAR FROM MY STEERING WHEEL SO I KNOW I DID NOT ACCIDENTLY HIT THE TRACTION CONTROL BY ACCIDENT. AFTER I WAS ABLE TO PULL OVER I WAS ADVISED TO HIT THE TRACTION CONTROL BUTTON TO SEE IF THAT WOULD FIX THE ERROR IN...

IN DECEMBER 2010 THE CAMSHAFT IN THE 5.3L GM ENGINE REPORTEDLY DELAMINATED CAUSING ONE OR MORE LIFTERS TO GALL AND FAIL REQUIRING A NEW ENGINE. I PURCHASED A FACTORY 5.3L ENGINE FROM A GM DEALER AND HAD THAT INSTALLED BY A CERTIFIED MECHANIC WITH THE ASSURANCE OF A 3 YEAR 100,000 MILE WARRANTY. 28 AUGUST MY WIFE TOLD ME THE ENGINE WAS NOISY. ON STARTING THE ENGINE IT WAS OBVIOUS THAT OIL WAS NOT PUMPING THROUGH THE LIFTERS. I TOOK THE TRUCK TO THE DEALER ON THE 29TH FOR DIAGNOSIS. ON 30 AUGUST THEY CONCLUDED THAT THE ENGINE NEEDED TO BE REPLACED. SUBSEQUENT INVESTIGATION CONFIRMED THAT THE ENGINE WAS SHIPPED WITH FAULTY CASTECH HEADS THAT CAUSED COOLANT TO SEEP INTO THE OIL. THE ENGINE WAS REPLACED UNDER WARRANTY. I WOULD LIKE, IF IT IS THE JOB OF THE NHTSA, TO HAVE THE 5.3L ENGINE RECALLED. *TR
