2004 Chevrolet Silverado Engine Problems

ENGINE LIGHT COMES ON WHILE DRIVING, ENGINE POWER DROPS IMMEDIATELY, NO POWER AT ALL. I GET A MESSAGE THAT SAYS ENGINE POWER FAILURE. I CAN STOP AND SHUT TRUCK OFF WAIT ABOUT 10-20 MINUTES, CRANK TRUCK, LIGHT GOES OUT AND ENGINE HAS POWER. THIS HAS HAPPENED 4 TIMES WITHIN THE LAST 2 MONTHS. TWICE THIS HAPPENED IN THE CITY LIMITS AND TWICE ON THE HIGHWAY.

CHECK ENGINE LIGHT IS ON, FUEL GAUGE NOT WORKING, HAD HEAVY GAS FUMES WHEN DRIVING AND AFTER TURNING ENG OFF, NOW I'M SEEING GAS LEAKING ON PAVEMENT COMING FROM UNDERNEATH AND BETWEEN CAB AND BED, FUMES ARE VERY STRONG, THERE'S SOME ELECTRICAL ISSUES WITH DASH LIGHTS AND STARTING TRUCK IS NOW NOT WANTING TO START 1ST TRY

VEHICLE IS LEAKING COOLANT WITH NO APPARENT CAUSE. NO EXTERNAL LEAKS WHAT SO EVER. TOOK IT TO A MECHANIC THAT DETERMINED IT WAS A CRACKED HEAD CAUSED BY A BAD CASTECH HEAD. THERE IS COOLANT LEAKING INTO MY OIL BECAUSE OF THIS.

EXHAUST MANIFOLD BOLTS BREAKING OFF. ALMOST EVERYONE I KNOW IS HAVING THIS PROBLEM WITH THE V8 GM ENGINES. LEADS TO EXHAUST LEAKS, SENSOR FAILURES AND BAD CATALYTIC CONVERTERS- THUS FAILING EMISSIONS TESTING. HARD AND EXPENSIVE TO FIX.

PASSENGER SIDE EXHAUST MANIFOLD BOLTS RUST AND BREAK OFF ON ALL GM FULL SIZE TRUCKS.

SEEMS ALL TRUCK ENGINES HAVE THIS PROBLEM FROM 1999 -2007. THIS SOUNDS LIKE A MANUFACTURING DEFECT THAT SHOULD BE ADDRESSED BY GM .

TICKING UNDER HOOD. EXHAUST LEAK DUE TO BROKEN EXHAUST MANIFOLD BOLT PASSENGER SIDE NEAR FIREWALL. TRIED TO LOOSEN OTHER BOLTS, 3 MORE BROKE. TRUCK HAS VERY LOW MILES, 8.1L MOTOR. INTERNET SHOWS THOUSANDS OF SAME ISSUES. BOLTS USED ARE VERY THIN FOR WHAT THEY DO. *TR

AFTER DISCOVERING AN EXHAUST LEAK PERFORMED A VISUAL INSPECTION OF THE ENGINE. I HAVE A 2004 SILVERADO WITH THE 6.0L. I AVE DISCOVERED THAT THERE ARE AN ABUNDANCE OF THESE VEHICLES OUT THERE WITH THE SAME PROBLEM. THIS IS CAUSING EXHAUST FUMES TO ENTER THE ENGINE COMPARTMENT AND CAB OF THE VEHICLE. *TR

I HAVE HAD A SLOW COOLANT LOSS RECENTLY WITHOUT AND LEAK VISIBLE. FOUND OUT ITS MY HEADS THAT NEED TO BE REPLACED DUE TO CRACKS. READ A LOT OF ARTICLES OF PEOPLE WITH THE SAME PROBLEM. SEEMS TO ME GM SHOULD BE RESPONSIBLE FOR INSTALLING HORRIBLE HEADS. *TR

WAS PICKING UP MY CHILDREN FROM SUMMER SCHOOL AND HAD THE AIR CONDITIONER ON. I FELT THE COOL AIR HITTING ME BUT STILL FELT SOME HEAT...I THOUGHT IT WAS THE SUN HITTING ME THROUGH THE FRONT WINDSHIELD. MY SON COMPLAINED THAT HE WAS HOT AND THERE WAS HOT AIR HITTING HIM. I REACHED OVER AND FELT THE AIR COMING OUT OF THE PASSENGER SIDE AND IT WAS EXTREMELY HOT!!! IF MY SON WOULD OF BEEN SITTING ON THE FRONT SEAT HE COULD HAVE GOTTEN BURNED BY THE HOT AIR! I PULLED OVER AND TRIED CLOSING THE VENTS AND TURNED OFF THE A/C BUT HOT AIR STILL CAME THROUGH THE VENTS. THIS IS DANGEROUS, IF ELDERLY PEOPLE OR PEOPLE WITH SENSITIVE SKIN ARE SITTING IN THE FRONT AND THE A/C IS ON AND ALL OF A SUDDEN IT STARTS BLOWING SUPER HOT AIR A PERSON CAN GET BURNED!!! YOU NEED TO LOOK INTO THIS AND GET IT RECALLED. *TR

I HAVE THE CASTECH HEADS ON MY TRUCK THAT ARE KNOWN FOR GETTING CRACKS IN THEM AND LEAKING ANITIFREEZE INTO THE ENGINE. THE WAY IT SOUNDS THERE SHOULD OF BEEN A RECALL ON THESE HEADS, THIS ISN'T A NORMAL WEAR AND TEAR DEAL. WHY SHOULD THE CONSUMER PAY FOR THE COST OF REPLACING SOMETHING THAT OBVIOUSLY IS A MANUFACTURER DEFECT SINCE MORE THAN JUST ONE PERSON IS COMPLAINING. IT SEEMS LIKE ALSO THAT GM HAS HELPED A FEW PEOPLE AND THEN TOLD OTHERS THAT THEY CAN'T HELP. *TR

IN WYOMING, TRAVELING I90 TO HYW 16 MOUNTAIN PASS...7 PER CENT GRADE....AFTER TWO MILES ENGINE OVERHEATED AND HAD TO PULL OVER TO LET ENGINE COOL DOWN...HAD TO TAKE ANOTHER ROUTE TO BYPASS MOUNTAIN. GOOGLED DURAMAX OVERHEATING AND FOUND THIS WAS A VERY COMMON PROBLEM ON THE 2004 DURAMAX DIESEL..DESIGN PROBLEM PREVENTED ADEQUATE AIR FROM ENTERING ENGINE...SHOULD HAVE BEEN A RECALL OR AT LEAST GM SHOULD HAVE OFFERED A SOLUTION... *JS

ANTI-FREEZE ALWAYS LOW, BUT NO SIGNS OF LEAKAGE. DUE TO BAD HEADS ON VEHICLE CAUSING COOLANT TO ENTER THE ENGINE CAUSING SLUG DAMAGE, WHICH DESTROYED THE VALVES. THIS IS NOT A WEAR AND TEAR PROBLEM. THIS IS A MANUFACTURER ISSUE THAT THEY NEED TO TAKE CARE OF. GM KNEW THAT THEIR MANUFACTURER OF THE HEADS KNEW IT WAS AN ISSUE AND POSTED A BULLETIN, BUT REFUSES TO FIX THE ISSUE AND RESULTING IN US TAKING IT TO A DEALERSHIP TO FIND OUT THE ENGINE NEEDS TO BE REPLACED. CONTACTED GM, ON JUNE 7, 2014 AFTER GETTING THE CAR BACK FROM THE DEALERSHIP, TO HELP WITH THE REPLACEMENT COSTS AND GOT NO HELP WHATSOEVER DUE TO AGE OF VEHICLE WITH LESS THAN 100,000 MILES. I EVEN ASKED IF THEY WOULD PAY FOR THE ENGINE IF I PAID FOR THE LABOR TO HAVE IT INSTALLED. THEY REFUSED. PLEASE GM OWN UP TO YOUR RESPONSIBILITIES, STAND BY YOUR PRODUCT, AND FIX THE ISSUES AT HAND. *TR
