DURING A UTAH STATE SAFETY INSPECTION LAST YEAR IT WAS FOUND THAT 3 OF THE 12 EXHAUST MANIFOLD BOLTS WERE BROKEN ON MY 6.0L ENGINE. THE BOLT HEADS WERE COMPLETELY BROKEN OFF/MISSING. THE BROKEN BOLTS ALLOW THE EXHAUST MANIFOLDS TO LEAK CAUSING PROBLEMS WITH EMISSIONS. IF LEFT UNDETECTED THIS PROBLEM CAN CAUSE THE CATALYTIC CONVERTER TO FAIL. JUST TO HAVE THE BOLTS REPAIRED IS A VERY EXPENSIVE >$500 REPAIR THAT COULD HAVE BEEN AVERTED BY HAVING THESE FAULTY BOLTS CHANGED OUT EARLY ON. ONCE THE BOLTS ARE BROKEN THEY HAVE TO BE EXTRACTED WHICH IS VERY DIFFICULT DUE TO THE THERMAL DEFORMATION AND CORROSION. TWO OF THE BOLTS WERE IN THE REAR MOST HOLES WHICH HAVE VERY LIMITED ACCESS. I HAVE NOT RECEIVED ANY NOTICES FROM THE MANUFACTURER IN REGARDS TO THIS PROBLEM. I HAVE OWNED THIS TRUCK SINCE IT WAS NEW. I WOULD LIKE TO REQUEST A RECALL FROM THE MANUFACTURER DUE TO THE FACT THAT IT CAUSES EMISSIONS PROBLEMS AND INCREASES POLLUTION. IF YOU CONSIDER HOW MANY OF THESE TRUCKS, TAHOES, AND SUBURBANS HAVE BEEN ON THE ROAD SINCE 1999, THE INCREASE IN POLLUTION IS CONSIDERABLE. *TR

I AM WRITING TO SEEK SOME ASSISTANCE WITH AN INFERIOR PRODUCT PRODUCED BY GM. I HAVE A CHEVY 2000 SILVERADO Z71 PICK UP THAT HAS PISTON SLAP STARTING AT AROUND 15K MILES AND PROGRESSIVELY WORSENED WHICH THE DEALER STATES IS NORMAL WEAR. THIS EXPENSIVE VEHICLE ALSO HAS A REAR END BANG INTO DRIVE AND THEN REVERSE AGAIN THE DEALER STATES IS NORMAL. RECENTLY I FIXED A SNAPPED CABLE FOR THE DRIVERS WINDOW WHICH THE SAME KIND OF CABLE WAS RECALLED FOR THE TAIL GATE CABLES. I HAVE REPLACED RECALL ITEMS FOR THE TAIL GATE CABLES, DRIVE SHAFT YOLK AND THE ABS SENSORS TO WHICH IT IS STILL NOT FUNCTIONING PROPERLY. ALL OF WHICH WHEN PRESENTED TO THE DEALER AND THE RESPONSE WAS IT IS NORMAL, UNTIL THE RECALL OCCURRED. IT SEEMS THE POLICY OF A COMPANY WHICH CREATES AN INFERIOR PRODUCT IS TO STATE, "IT IS NORMAL" TO THE CONSUMER UNTIL THE GOVERNMENT STEPS WHEN ENOUGH PEOPLE COMPLAIN AND MAKES THE DEALER OWN UP TO THE PROBLEMS WITH THE PRODUCTS AND FINALLY TREATS THE CONSUMER WITH MORE COMPASSION, AND TO SOME DEGREE "DECENCY". WITH THE MANY PROBLEMS WITH THIS VEHICLE THE GOVERNMENT NEEDS TO STEP IN AND HELP THE CONSUMER WITH THE DEALERSHIP RESISTANCE TO FIX THE PROBLEMS CAUSED BY MORE CONCERN FOR PROFIT THAN QUALITY. *NM

I HAVE TWO GENERAL MOTORS VEHICLES. A 2000 SILVERADO TRUCK AND A 97 OLDS SILHOUETTE. BOTH OF THESE HAVE V6 ENGINES AND NOW I AM BEING TOLD THAT BOTH OF THEM HAVE INTAKE MANIFOLD LEAKS. THE ANTIFREEZE IS LEAKING OUTSIDE OF THE INTAKE, AND IN THE CASE OF MY TRUCK, PROBABLY INTO THE ENGINE. I AM BEING TOLD THREE DIFFERENT MECHANICS, THAT THIS IS A VERY COMMON PROBLEM WITH THE V6. AND AFTER VOICING MY COMPLAINT, FOUND THAT MY BROTHER-IN LAW, HAS HAD THE SAME PROBLEM. I CALLED THE GENERAL MOTORS NUMBER IN THE MANUAL AND TOLD THEM THAT I WAS UPSET WITH THE PROBLEMS AND THEY SAID THAT BECAUSE ONE IS A 97 WITH 62000 MILES, IT IS TWO OLD AND THAT MY TRUCK HAS TO MANY MILES (112000). YET EVERYONE TELLS ME THAT IT IS THE PLASTIC INTAKE MANIFOLDS THAT GM USES THAT IS THE PROBLEM. *NM

EXCESSIVE TICKING AND ENGINE NOICE DURING COLD START UPS. I WAS TOLD, BY CHEVROLET SERVICE THE TICKING WAS NORMAL BUT SHOULD NOT LAST MORE THAN 1 MINUTE. HOWEVER AFTER DIGANOSING THE PROBLEM, IT WAS DISCOVERED THAT MY 2000 CHEVROLET SILVERADO 1500 HAS A BAD LIFTER. THIS AFTER ONLY 38000 MILES. I FILED A CLAIM WITH CHEVROLET THEY REFUSED TO PICK UP ANY OF THE $1300. IN REPAIR COSTS. MY TRUCK HAS A VORTEX V6, WHICH GM HAS BEEN MANUFACTURING IN EXCESS OF 20 YEARS. THE BUGS SHOULD BE WORKED OUT BY NOW, BUT AFTER READING THE NUMEROUS COMPLIANTS, WITH REGARD TO THE SAME PROBLEM, THE BUGS CLEARLY HAVE NOT BEEN WORKED OUT.*AK

WE PURCHASED A 2000 SILVERADO 2500. THERE IS A KNOCKING NOISE IN THE ENGINE. WE TOOK IT BACK TO THE DEALERSHIP TO LOOK AT AND NOTHING COULD BE DONE ABOUT IT. GM IS WELL AWARE OF THE KNOCKING NOISE IN THE VORTEX 6.0 ENGINE. THEY TOLD US THAT THIS WAS A COMMON PROBLEM. IT DOES NOT MATTER IF IT IS A COLD START OR IF IT RUNS ALL DAY.*AK

I OWN A 2000 5.3 VORTEX V8 IN MY CHEVROLET AND THE ENGINE MAKES HORRIBLE NOISE WHEN ITS COLD, REFERRED TO AS SLAPPING OF THE PISTON SLEEVE. WHAT CAN BE DONE ABOUT THIS IF ANYTHING. SEEMS LIKE AN ON GOING PROBLEM FOR MANY GM OWNERS AND SOMETHING THAT IS ONLY RESOLVED ONCE A BIG STINK IS MADE OF IT BEFORE ANY POSSIBLE ACTION IS DONE. I REALLY LOVE MY TRUCK BUT, THIS IN CONJUNTION WITH THE NOISE I GET IN COLD WEATHER GOING OVER SPEED BUMPS OR UNLEVELED SURFACES IN THE SHOCK OR THE FRAME. I HAD ALL KINDS OF PARTS REPLACED AND IT STILL COMES BACK IN COLD WEATHER, ALONG WITH THE KNOCKING NOISE ON COLD STARTS. ANY ADVISE OUT THERE FOR A RESOLUTION? THANKS NHALL. *AK

MY 5.3 LITER SILVERADO HAS A DIESEL LIKE NOISE IN THE MOTOR UNTIL IT REACHES NORMAL RUNNING TEMPERATURE, THEN IT RUNS GREAT. ITS VERY LOUD THE FIRST 30 SECS. FROM A COLD START. MY LOCAL GM GARAGE SAID THAT IS NORMAL FOR A 4.8 AND A 5.3 MOTOR. THEY CALLED IT PISTON SLAPPING, TO ME IT IS VERY ABNORMAL. AND WILL IT GET WORSE, I ASKED. THEY HAD NO ANSWER. THEY DID COMMENT THAT GM HAS NOT RESOLVED THIS BULLETIN YET. I LOVE MY TRUCK, I HOPE I GET 200K MILES OUT OF IT. NOW I ONLY HAVE 50K . WHAT'S A PERSON TO DO IF THE MAKER OF HIS FAVORITE AUTO CAN'T COME THROUGH WITH A RESOLUTION. IT ALSO AFFECTS RESALE VALUE IF I DECIDE TO SELL. *JB
