2011 GMC YUKON DENALI XL Engine Problems

ONE WEEK AFTER PURCHASING THE VEHICLE I BROKE DOWN DUE TO AN OIL PRESSURE SENSOR. TWO WEEKS AFTER THAT I BROKE DOWN (STALLED OUT IN THE ROAD) DUE TO 2 LIFTERS COLLAPSING AND THE CAMSHAFT BEING DAMAGED. AFTER REPLACING ALL LIFTERS, THE CAMSHAFT, SPARK PLUGS AND WIRES, AS WELL AS ANOTHER OIL PRESSURE SENSOR JUST IN CASE THE OTHER ONE WAS BAD I STILL HAVE LOW OIL PRESSURE. THIS COST $3,000.00! I LEFT THE SHOP AND BROKE DOWN ON MY WAY HOME WITH A FLASHING ENGINE LIGHT AND THE STABILITRAK LIGHT AND MESSAGE FLASHING. IT SHOOK SO HARD I THOUGHT IT WOULD EXPLODE IN THE ROAD AND THEN STALLED OUT! IT WAS TOWED BACK TO THE SHOP WHERE IT CONTINUES TO SIT. ITS BEEN THERE 3 WEEKS. ITS BEEN AT THE SHOP LONGER THAN I'VE GOTTEN TO DRIVE IT. AFTER GOOGLING WHAT MIGHT BE CAUSING THE PROBLEM IT APPEARS THIS...

TRUCK STARTED SPUTTERING WHILE DRIVING. I HAD IT TOWED HOME AND THEN TOWED TO THE DEALER AND THEY STATED THE LIFTERS IN THE ENGINE WERE BROKE AND THERE WAS DAMAGE TO THE CAN SHAFT. TOLD ME THIS IS NORMAL AND HAPPENS TO VEHICLES LIKE MINE REGULARLY. I HAVE ONLY OWNED THE TRUCK THREE YEARS AND HAVE MAINTAINED IT WELL WITH LOW MILEAGE.THEY TOLD ME IT WOULD BE $6700 TO FIX. WHEN I COMPLAINED, THE REP TOLD ME $5500. I ASKED FOR A SUPERVISOR WHO THEN STATED THAT GMC WOULD OFFSET THE COST AND IT WAS NOW $3311. IT WOULD SEEM THAT IF THIS IS A REGULAR OCCURRENCE IN VEHICLES LIKE MINE, GMC WOULD DO SOMETHING TO ENSURE IT DOESN'T HAPPEN. IN ADDITION THERE IS STILL NO REMEDY AVAILABLE FOR THE TAMARA INFLATOR.

VALVE LIFTERS NEED REPLACED. RESEARCHED AND THIS IS A COMMON ISSUE SEVERAL PEOPLE ARE HAVING WITH THIS TYPE OF VEHICLE. REPAIR SHOP ALSO SAID A COMMON REPAIR FOR THIS MODEL.
