WHILE DRIVING 35 MPH TO A FAMILY FUNCTION THE LOW OIL PRESSURE LIGHT CAME ON. THE PRESSURE GAUGE THEN STARTED CHANGING FROM 0-80 CONTINOUSLY. AFTER GOOGLE SEARCH I FOUND THAT I SHOULD PULL OVER AND TURN OFF THE ENGINE. I TOOK IT TO AN INDEPENDENT MECHANIC WHERE HE CHECKED THE OIL AND IT HAD THE RIGH AMOUNT OF OIL AND HE STATED THAT THE OIL LOOKED GOOD. I TAKE MY TRUCK REGULARLY FOR OIL CHANGES AND MY LAST ONE WAS MAY 1. 2015. THE MECHANIC TOLD ME THAT IT MAY BE THE OIL PUMP SO WE REPLACED IT. THE COST FOR THE SERVICE WAS $200. IT IS NOW ONLY A FEW DAYS LATER AND THE OIL PRESSURE GAIGE IS STILL GOING FROM 0-80.

I OWN A 2005 CHEVY TAHOE WITH 5.3 LITER ENGINE. THE MOTOR HAS CONSUMED 2 QUARTS OIL SINCE ITS LAST OIL CHANGE. THE VEHICLE CURRENTLY HAS 83000 MILES. IT IS SERVICED REGULARLY. CHEVROLET IS WELL AWARE OF THIS PROBLEM AND NEEDS TO ADDRESS IT IMMEDIATELY. I AM TOLD BY MY LOCAL CHEVROLET DEALERSHIP THAT IT HAS REPAIRED NUMEROUS VEHICLES BECAUSE OF THE OIL CONSUMPTION ISSUE. THE COST TO REPAIR IS BETWEEN 300 AND 3000 DOLLARS. IT MIGHT NEED NEW PISTONS AND RINGS BECAUSE OF THE FAULTY INEXPENSIVE PART. EPIC FAIL BY CHEVY NOT TO ALERT THEIR CUSTOMERS OF THIS PROBLEM.

ENGINE

APPROXIMATELY 5:50 P.M. AS MY DAUGHTER AND I WERE DRIVING DOWN A BUSY ROAD THE CAR STOPPED WITHOUT WARNING. MANY OF THE DASHBOARD LIGHTS CAME ON AND THE STEERING LOCKED. I WAS ABLE TO CRANK AGAIN TO PULL IT INTO A BUSINESS PARKING LOT. I WAS NOT COMPLETELY IN THE PARKING SPACE AND WAS CONCERNED ABOUT UPSETTING THE FLOW OF TRAFFIC FOR THIS BUSINESS, BUT COULD NOT CRANK THE CAR TO GET IT COMPLETELY IN THE PARKING SPACE. AS I WAS OUT OF TOWN, THE VEHICLE HAD TO BE TOWED APPROXIMATELY 75 MILES. WHEN THE GUY CAME TO TOW THE CAR ALL THE LIGHTS WERE STILL ON, STEERING STILL LOCKED AND UNABLE TO START ENGINE UP. THE GUYS AT THE CHEVROLET DEALERSHIP WHERE IT WAS TOWED STARTED WORKING ON THE VEHICLE ON FRIDAY MORNING BY CLOSING THEY STILL HAD NOT FIGURED OUT THE PROBLEM WITH THE CAR. AROUND LUNCH TIME ON MONDAY THEY REALIZED IT WAS THE IGNITION SWITCH. THE PART WAS $49.52 BUT THE LABOR WAS COSTLY. I ENDED UP PAYING $476 TO HAVE THE VEHICLE REPAIRED. REALLY DID NOT FEEL SAFE DRIVING THE CAR FOR QUITE SOME TIME. CAN'T BELIEVE MY VEHICLE WILL NOT BE COVERED UNDER THIS RECALL WHEN IT IS THE EXACT SAME SYMPTOMS. MY STATEMENT ON THE REPAIR ORDER STATES, "THE CUSTOMER SAYS THE CAR STOPPED AS SHE WAS DRIVING DOWN THE ROAD."

ENGINE

THE ENGINE HAS COOLANT LEAK AT HEAD. GM IS AWARE THAT THE ENGINES WERE MADE WITH FAULTY HEADS BY A COMPANY CALLED CASTEC THAT ARE PRONE TO FAILURE IN THE OIL RETURN PORTS. THEY HAVE A BULLETIN BUT ARE UNWILLING TO ASSUME ANY RESPONSIBILITY. THIS REPAIR IS SO COSTLY THAT A COMPLETE ENGINE REPLACEMENT IS MORE FEASIBLE. THE AVERAGE TIME OF THIS REPAIR SEEMS TO BE ONLY 100,000 MILES.

MY BOLTS ON MY EXHAUST MANIFOLD ARE BREAKING OFF. I HAVE FIVE GRAND KIDS THAT RIDE IN MY TRUCK AT TIMES. I DON'T WANT CARBON MONOXIDE COMING INTO MY TRUCK. THESE BOLTS SHOULD NOT JUST BREAK OFF, THIS IS AN EXPENSIVE REPAIR AND SHOULD BE RECALLED BY THE MANUFACTURER. I HAVE SEEN WHERE THIS HAS BEEN AN ON GOING ISSUE WITH CHEVY AND GM TRUCKS. THIS TRUCK WAS BUILD WITH FAMILY IN MIND. NOW BECAUSE OF THIS ISSUE MYSELF AND MY FAMILIES SAFETY IS AT RISK.
