I GOT AN ENGINE LIGHT ABOUT BEGINNING OF NOVEMBER CODE WAS P0430, DEFINITION IS "CATALYST SYSTEM EFFICIENCY BANK 2", THIS COULD BE CAUSED BY HIGH ENGINE OIL OR COOLANT USAGE. KNOWING THIS I CHECK MY TAHOE FOR COOLANT LEAKS, NO VISIBLE LEAKS AT ALL, I TAKE THE COVER OFF THE CYLINDER HEAD AND I FIND A LOT OF SLUDGE, NOW I KNOW WHERE THE ANTIFREEZE IS GOING. MY TAHOE IS STILL RUNNING BUT WITH THE ENGINE LIGHT ON AND WITH A MISFIRE DUE TO THE POROUS CYLINDER HEAD, DON'T KNOW HOW MUCH MORE IS GOING TO LAST AND CAN'T REALLY STOP THE TAHOE BECAUSE IT'S A DAILY DRIVER. *TR

VEHICLE BEGINS TO IDLE ROUGH, NOTICED TAHOE CONSUMES COOLANT AT AN ABNORMAL RATE, APPROXIMATELY 1GAL/MONTH!! OUR LOCAL CHEVY DEALER CODED FOR FLEX FUEL SENSOR REPLACEMENT $1400! NO CHANGE IN CONDITION OF VEHICLE. IDLE IS NOW VERY VERY LOW! MY WIFE PICKS UP OUR KIDS, TAHOE WOULD STOP RUNNING WHILE MAKING A TURN AT AN INTERSECTION!!! NO POWER = NO POWER STEERING!! SHE BARELY AVOIDS AN ACCIDENT!! SHE ALONG WITH THE KIDS WILL NOT RIDE IN THE (FAMILY CAR) THE TAHOE UNTIL IT IS FIXED. DON'T TRUST OUR LOCAL CHEVY DEALERSHIP, DUE TO LACK OF INTEGRITY!! WE WERE PROUD AND LOYAL CHEVY OWNERS, WE ALSO OWN A 91 GMC SIERRA 1500 5.7L WITH 232000 MI. AND A 98 CHEVY 1500 V-6 113590 MI PICK-UP, BOTH STILL RUNNING VERY STRONG WITH ABSOLUTELY NO ISSUES! RESEARCHED THIS ISSUE, DEFECTIVE CASTECH HEADS, GM IS AWARE OF THIS PROBLEM, TSB 06-06-01-019B, VERY DISAPPOINTED TO STATE THE LEAST OF HOW GM IS HANDLING THIS SITUATION. COMPLAINED TO GM CORPORATE, THEY STATED THEY WILL NOT BE ABLE TO ASSIST AND THAT WE WOULD HAVE TO TAKE IT TO OUR LOCAL DEALERSHIP WHERE INTEGRITY RUNS VERY THIN!! I AM A PROUD MSGT IN THE USAF, AND FULL TIME FIREFIGHTER, IF WE CANT TRUST "THE HEARTBEAT OF AMERICA," WHO THE HELL CAN WE TRUST!! THIS PROBLEM HAS COST PUT OUR FAMILY IN THE HOLE FOR $3800 NOW AND IT LOOKS LIKE IF WE MOVE FORWARD TO FIX OURSELVES WE WILL BE IN EXCESS OF $5800 FOR THE HEADS TO BE SERVICED OR $8600 FOR NEW MOTOR SWAP!!! GM NEEDS TO TAKE RESPONSIBILITY RECALL THIS AND GET THIS ISSUE SQUARED AWAY AND MAYBE SALVAGE WHAT IS LEFT OF A LOYAL GM SUPPORTER. *TR

THE ENGINE CYLINDER HEADS FOR THE 5.3L GM MOTORS BUILT BY CASTECH LEAK COOLANT INTO THE ENGINE CAUSING ENGINE OVERHEAT AND INTERNAL ENGINE FAILURES. GM HAS ISSUED A TECHNICAL BULLETIN #060601019B TO ADDRESS THE ISSUE AND DIAGNOSE THE ISSUE. GM WILL NOT OFFER CUSTOMERS ANY FINANCIAL HELP IN THE REPLACEMENT OF THE DEFECTIVE PARTS. THIS ISSUE EFFECTS THE SAFETY OF THE VEHICLE AND THE SAFETY OF THE PERSONS IN AND AROUND THE VEHICLE. THE FOULED ENGINE OIL CAUSES THE LIFTERS TO FAIL, THE OIL PRESSURE TO DROP AND THE ENGINE TO LOCK UP DUE TO LACK OF LUBRICATION BY THE FOULED OIL AND THE DRIVER HAS NO WAY OF KNOWING THIS IS HAPPENING AS THERE IS NO EXTERNAL INDICATORS. *TR

DROVE VEHICLE OUT OF TOWN ON CHRISTMAS HOLIDAY TRIP. AFTER BEING PARKED OVERNIGHT STARTING VEHICLE NEXT AM BIG CLOUD OF WHITE GRAY SMOKE UPON START. COOLANT LOW. REFILLED COOLANT AND DROVE HOME. NOW VEHICLE CONSTANTLY LEAKS COOLANT WITH NO APPARENT LEAK UNDER VEHICLE OR IN ENGINE COMPARTMENT. OIL SLUDGES BETWEEN OIL CHANGES. WHITE SMOKE AFTER A 30 MIN DRIVE EVERY TIME. GM HAS BULLETIN OUT FOR BAD HEADS INSTALLED AND THE PART NUMBER AND SYMPTOMS MATCHED CRACKED HEADS ON MY VEHICLE. DEALER AWARE AND SEES OFTEN NOT ONLY IN THIS VEHICLE BUT ALL 5.3 ENGINES FROM A CERTAIN TIME SPAN. DEALER STATES WILL ONLY FIX AT COST OF CONSUMER EVEN THOUGH BULLETIN IS KNOWN. THIS COULD CAUSE AN OVERHEAT SITUATION OR ENGINE FAILURE AT A BAD TIME OR WORSE. WHY ARE THEY NOT MADE TO STAND BEHIND THIS WHEN PROBLEM IS KNOWN? A QUICK SEARCH ON GOOGLE WILL OVERWHELM A COMPUTER WITH SO MANY ACCOUNTS OF THIS PROBLEM. *TR

I WAS DRIVING DOWN THE ROAD WHEN MY 2004 CHEVROLET TAHOE CAUGHT ON FIRE BURNING TO THE GROUND. THE REPORT FROM THE FIRE DEPARTMENT SAYS THAT THE FIRE STARTED DUE TO FAILURE OF EQUIPMENT OR A HEAT SOURCE AND THAT THERE WERE NO HUMAN FACTORS CONTRIBUTING TO THE FIRE.WHILE LOOKING ON THE INTERNET I HAVE FOUND AT LEAST ONE OTHER PERSON THAT HAS ENCOUNTERED THE SAME PROBLEM WITH HER 2004 CHEVROLET TAHOE. *TR

THE TAHOE HAS KNOWN FAULTY CASTECH CYLINDERS WHICH CAUSE COOLANT TO LEAK WITH NO EXPLANATION. OVER THE WINTER I HAVE HAD UNEXPLAINED COOLANT/ANTIFREEZE ISSUE WITH NO FOUND LEAKS (COOLANT WOULD BE BONE DRY AFTER A COUPLE WEEKS OF FILLING IT). I WAS TOLD THE ISSUE IS PROBABLY CAUSED BY THE FAULTY POROUS CYLINDER HEADS MADE BY CASTECH INSTALLED IN GM'S FROM 2001 - 2006. THIS TAHOE HAS A TOTAL OF 80,000 MILES NOW AND EXPERIENCING ISSUES DUE TO KNOWN FAULTY PARTS INSTALLED BY GM. CHEVROLET HAS TO BE AWARE OF THE DANGER THEY ARE PUTTING THEIR CUSTOMERS IN BY NOT HAVING A RECALL OF A FAULTY PART LOCATED IN THE ENGINE. HOW THERE HAS NOT BEEN A RECALL I DO NOT UNDERSTAND. HOW CHEVROLET EXPECT THE CUSTOMER TO PAY 3-4K TO REPLACE THEIR FAULTY HEAD IS LUDICROUS. *TR
