2005 Chevrolet Tahoe Engine Problems

While your Tahoe was idling at a traffic light, you noticed a strong coolant smell and white smoke coming through the air vents with a burning odor. When you checked the oil dipstick, you found water mixed in with the oil. This combination of symptoms suggests coolant is leaking into the engine's oil system, which is a serious problem. You'll likely need a mechanic to diagnose whether you have a head gasket failure, cracked head, or another internal engine leak.

THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 145,000.

I HEARD A TICKING NOISE IN THE ENGINE COMPARTMENT, UPON INVESTIGATION OF WHERE THE NOISE WAS COMING FROM, FOUND A EXHAUST MANIFOLD BOLT MISSING. RESEARCH INDICATES THIS IS A COMMON OCCURRENCE ON THESE TYPE VEHICLES

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. *TR

TL* THE CONTACT OWNS A 2005 CHEVROLET TAHOE. THE CONTACT STATED THAT TWO OF THE REAR EXHAUST MANIFOLD BOLTS SHEARED OFF ON BOTH SIDES OF THE ENGINE. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIAN STATED THAT THE BOLTS HAD TO BE DRILLED OUT IN ORDER TO BE REPLACED. THE MANUFACTURER AND DEALER WERE MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 98,000. THE DEALERS EXPLANATION WAS AN ALUMINUM HEAD VERSUS A CAST IRON EXHAUST MANIFOLD VERSUS CASE HARDENED BOLTS ALL EXPANDED AND CONTRACTED TOGETHER, WHICH CAUSE A POOR DESIGN. UPDATED 08/18/14

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. *TR

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. *TR

EXHAUST MANIFOLD BOLTS BREAKING OFF. EPA EMISSIONS . EXHAUST LEAK UNDER HOOD CAN GET INTO PASSENGER COMPARTMENT. *TR
