1999 Chevrolet Tahoe engine problems

ENGINE

SUSPECTED DEFECTIVE IGNITION SWITCH AND/OR IGNITION SWITCH PASSLOCK SECURITY ON OR ABOUT JAN 17 2014 I WAS TRAVELING ABOUT 30 MPH WHEN THE ENGINE STALLED WITH LOSS OF POWER STEERING AND BRAKES. I WAS ABLE TO STOP WITHOUT INCIDENT. AFTER 10-15 MINUTES I WAS ABLE TO RESTART THE VEHICLE AND DRIVE AS NORMAL. FOR SEVERAL YEARS AFTER DRIVING THE IGNITION KEY WAS WARM OR HOT WHEN REMOVED FROM THE SWITCH. IN EARLY 2013 THE ENGINE WOULD OCCASIONALLY STALL IMMEDIATELY AFTER STARTING BUT WOULD RESTART AFTER WAITING 5 TO 10 MINUTES. ON JAN 14 WHEN AT A GAS STATION THE ENGINE STALLED BUT I WAS ABLE TO MOVE THE CAR TO THE CURB. AFTER 10-15 MINUTES I WAS ABLE TO RESTART AND DRIVE NORMAL. * PASSLOCK IGNITION SECURITY FEATURE IS WIDELY REPORTED TO BE A CAUSE OF THESE SYMPTOMS.

ENGINE AND ENGINE COOLING

CONTINUOUSLY HAVING TO FILL WITH COOLANT DUE TO LEAK. NO LEAK FROM HOSES ETC. THE PROBLEM COMES FROM A DEFECT IN HEADS THAT ARE PRODUCED BY CASTECH. WENT ON LINE TO RESEARCH THIS AND FOUND NUMEROUS COMPLAINTS ABOUT THIS AND GM/CHEVROLET WILL NOT FIX. EXTENDED WARRANTY COMPANIES WILL NOT FIX BECAUSE IT IS A DEFECTIVE PART. DEALERSHIPS WILL NOT TALK ABOUT IT BUT IF YOU TALK TO AN MECHANIC AT A DEALERSHIP AND DESCRIBE THE PROBLEM THEY ARE QUICK TO TELL YOU EXACTLY WHAT IT IS AND THAT IT IS A DEFECT. THE COOLANT SEEPS THROUGH THE POORLY MANUFACTURED CASTECH HEADS. CALLED SOME OF THE LOCAL MECHANICS AND THEY ARE SAYING THE SAME THING-DEFECTIVE PART. NOW LIKE I SAID I HAVE CHECKED ON LINE AND HUNDREDS OR MORE PEOPLE ARE HAVING THIS PROBLEM AND ARE HAVING TO HAVE THE HEADS REPLACED AND ENGINES AT OUT OF POCKET. I DID NOT SEE WHERE A LOT OF PEOPLE ARE COMPLAINING ON THIS SITE BECAUSE LIKE ME THEY DID NOT KNOW WHERE TO GO. I FOUND OUT FROM A LAWYER WHO ALSO HAD THIS PROBLEM TO COMPLAIN ON THIS SITE. HE JUST SIMPLY GOT RID OF HIS TAHOE. ONE SAID THEY WERE STUCK ON THE SIDE OF THE INTERSTATE WITH YOUNG KIDS AND NO PHONE AND NO WAY OF AFFORDING TO GETTING HOME FROM OUT OF TOWN. NOW THAT IS BAD.

ENGINE AND ENGINE COOLING

I BROUGHT MY 1999 CHEVROLET TAHOE TO ALEXANDRIA BUICK-PONTIAC-GMC IN ALEXANDRIA, VIRGINIA ON DECEMBER 14, 2005 BECAUSE THE ABS LIGHT KEPT COMING ON IN THE DASHBOARD. MECHANIC DIAGNOSIS WAS SPEED SENSORS WERE MISSING. HE REPLACED THE HUB ASSEMBLIES AND SPEED SENSORS. TOTAL REPAIR WAS $1064.54. I THEN FOUND OUT THAT A RECALL ON THE PROBLEM I HAD JUST REPAIRED WAS GOING ON IN THE "RUST BELT" STATES AND CANADA. THE RECALL WAS FOR THE WHOLE NORTHEAST PART OF THE COUNTRY DOWN TO AND INCLUDING WASHINGTON DC. I WORK IN WASHINGTON AND LIVE ABOUT 5 MILES FROM THE CITY. I WROTE THE GM CLAIMS DEPARTMENT WITH COPIES OF EVERY RECEIPT AND A COPY OF THE RECALL LETTER. THEY CONTACTED ME AND TOLD ME THE REPAIR WAS INDEED ONE INCLUDED WITHIN THE RECALL, BUT THEY WERE DENYING THE CLAIM BECAUSE I LIVE IN VIRGINIA AND THE RECALL IS ONLY VALID IN "SALT BELT" STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MARYLAND, MASSACHUSETTS, MAINE, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN AND THE DISTRICT OF COLUMBIA. I WANT THE RECALL TO BE OPENED BACK UP AND TO INCLUDE ADDITIONAL STATES. I SPEND EVERY SINGLE DAY IN WASHINGTON, WHAT MAKES MY CLAIM ANY DIFFERENT FROM THE PERSON THAT LIVES 5 MILES AWAY FROM ME, BUT HAPPENS TO LIVE ACROSS THE STATE BORDER? WHAT IS DIFFERENT FROM SOMEONE WHO LIVES IN WASHINGTON AND WORKS IN VIRGINIA? SINCE MY HOME ADDRESS WAS VIRGINIA, MY CLAIM WAS DENIED. THE RECALL CAMPAIGN # IS 05V379000. *NM THE ENGINE LIGHT ILLUMINATED, THE SERPENTINE BELT WAS REPALCED. THE WATER PUMP WAS LEAKING ABD THE PINION SEAL WAS REPLACED. UPDATED 02/09/06.

THE AIR CONDITIONER LINES ON MY 1999 CHEVY TAHOE STARTED TO LEAK AND GM HAS TOLD ME THROUGHOUT THE SUMMER THAT THE PART NEEDED (PART #15010337) IS ON BACKORDER. THIS HAS BEEN A HOT SUMMER, AND WITH YOUNG CHILDREN AND AGING ADULTS, THIS IS NOT JUST UNACCEPATBLE, BUT DANGEROUS.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

MY HUSBAND AND I WERE IN ROUTE ONE EVENING WHEN THE CHECK ENGINE LIGHT CAME ON. FOLLOWING THE MANUAL'S INSTRUCTIONS: CHECK THE COOLANT GAGES, IT HAD A READING OF NEARLY 260. WE PULLED OVER AT THE NEXT EXIT, INTO THE PARKING LOT OF A GAS STATION. WE CHECKED THE COOLANT RECOVERY TANK, IT WAS EMPTY. INSPECTED THE ENGINE FAN, IT WAS OPERATING NORMALLY. WAITED 1 1/2 HRS TO LET ENGINE COOL DOWN. REMOVED RADIATOR CAP. RADIATOR WAS DRY. I ASKED THE GAS STATION FOR THE RECOMMENDED BRAND 'DEX-COOL'. FORTUNATELY, THEY DIDN'T CARRY THAT BRAND. (THE REPORTS I'VE READ TODAY, INDICATE BRAND DEX-COOL COOLANT IS THE #1 CAUSE IN GASKET CORROSIONS, IT EATS PLASTIC. ADDED A 50/50 COOLANT AND ARRIVED HOME WITHOUT FURTHER INCIDENT. THE FOLLOWING MORNING I TOOK MY VEHICLE TO A REPUTABLE MECHANIC. AFTER GIVING HIM A VERY BRIEF DESCRIPTION OF WHAT WE'D EXPERIENCED THE EVENING PRIOR, HE IMMEDIATELY STOPPED ME IN MID-SENTENCE AND SAID "VICKIE, YOU DON'T EVEN HAVE TO FINISH TELLING ME. I KNOW EXACTLY WHAT THE PROBLEM IS. IT'S COMMON FOR THIS ENGINE IN CHEVY'S FROM 1996 - 1999 TO LEAK COOLANT FROM THE INTAKE MANIFOLD NEAR THE REAR FIREWALL" HE WENT ON TO SAY, THAT THEIR SERVICE CENTER HAS HAD MANY CUSTOMERS COME IN WITH THE SAME COMPLAINT FREQUENTLY. HE ESTIMATED THE COST TO REPLACE THE INTAKE MANIFOLD GASKET IS BETWEEN $250 - $300. IF THIS IS SUCH A COMMON PROBLEM, THEN GM SHOULD NOT ONLY BE REQUIRED TO NOTIFY THE OWNERS, BUT SHOULD ASSIST IN THE COST TO REPLACE THE DEFECTIVE GASKETS. THE MECHANIC ALSO STATED, IF THE FLUID ENTERS THE ENGINE, WHICH COULD VERY WELL HAPPEN, THEN THE ENGINE WOULD LOCK-UP. THIS IS A SAFETY ISSUE, AND CAN EASILY BE PREVENTED. NEED THERE BE A FATALITY BEFORE GM VOLUNTARILY NOTIFIES THE OWNERS AND RECTIFY THIS PROBLEM? I DEMAND THAT GM INFORM CURRENT OWNERS OF THIS PROBLEM, REIMBURSE OWNERS WHO'VE ALREADY PAID TO HAVE THEIR VEHICLES REPAIRED, AND FINALLY, STOP RECOMMENDING THE USE OF DEX-COOL BRAND COOLANT IN THE OWNERS MANUAL!!!

THE HEATER HOSE IS ATTACHED AT THE INTAKE MANIFOLD WITH A QUICK-CONNECT FITTING THAT IS MADE OF POT METAL. WHEN THIS FAILS (AND IT IS INEVITABLE DUE TO THE TYPE OF METAL USED) THE ENGINE LOSES ALL COOLANT AND LEAVES YOU STRANDED. THERE IS NO "QUICK REPAIR" FOR THIS FAILURE. OLDER ENGINES HAD A CONNECTOR INTO THE INTAKE MANIFOLD MADE OF STEEL OR BRASS WHICH WAS MORE RELIABLE AND USUALLY DID NOT BREAK OFF FLUSH WITH THE MANIFOLD. NLM
