2000 CHEVROLET SILVERADO Engine And Engine Coolingenginegasoline Problems

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...

NOTICED ENGINE KNOCK ON COLD START-UPS AS SOON AS VEHICLE WAS PURCHASED. PURCHASED VEHICLE IN OCT. 2000, WITH 39,000 MI.(2ND OWNER) AT APPROX. 85,000 MI., NOTICED ENGINE MAKING A RATTLING NOISE AS TRANSMISSION UP-SHIFTED IN 1ST & 2ND GEARS AFTER COLD ENGINE START-UP KNOCK WENT AWAY. TOOK VEHICLE TO DEALER AND WAS TOLD THAT COLD START-UP KNOCK WAS NORMAL, BUT RATTLING WASN'T. DEALER GAVE ME SERVICE BULLETIN #01-06-01-028 WHICH STATES THAT COLD START-UP KNOCK MAY BE CAUSED BY AN INTERACTION BETWEEN CARBON ON PISTON, PISTON MOTION, AND CYLINDER WALL. VEHICLE PRESENTLY HAS 89,000 MI. ON IT AND APPROXIMATELY 80% OF SAID MI. ARE HIGHWAY MI., SO, CARBON IN MY ESTIMATION, DOESN'T COME INTO PLAY! AS FAR AS THE RATTLING SOUND GOES, DEALER FOUND THE HARDNESS BREAKING DOWN ON CAMSHAFT LOBES #1 AND #4 (FROM FRONT OF ENGINE). DEALER REPLACED CAMSHAFT, 2 LIFTERS, AND OIL PUMP. UPON COMPLETION OF SAID REPAIRS,...

5.3L ENGINE DEVELOPED A KNOCK AT APPROX 17000 MILES. COMPLAINT MADE TO GM DEALERSHIP, THEY ACKNOWLEDGED THE ISSUE AND STATED THAT "GM IS AWARE OF PROBLEM AND WORKING ON A FIX". GM NOW CLAIMS IT IS NORMAL ENGINE NOISE AND NO FIX REQUIRED. IF IT'S NORMAL WHY DON'T ALL THE 5.3'S DO IT ? GM HAS ISSUED ME AN "EXTENDED COMPONENT WARRANTY" FOR THE ENGINE ONLY FOR AN ADDITIONAL 2 YEARS AND 64K MILES AFTER EXPIRATION OF FACTORY 3/36. IF THEY WON'T FIX UNDER WARRANTY NOW WHAT GOOD IS AND EXTENDED WARRANTY?? GM NEEDS TO RESOLVE THIS ENGINE PROBLEM NOW BEFORE CUSTOMERS START SEEING ENGINE FAILURES AND ABNORMAL OIL USAGE BECAUSE OF IT. NHTSA, AS WELL AS STATE ATTORNEY GENERALS OFFICES NEEDS TO MAKE GM RESOLVE THIS ISSUE OF CONSUMER FRAUD FOR NOT HONORING THE WARRANTY AND TO RESOLVE THE ISSUE.*AK

CHEVROLET HAS DENIED THAT THEIR 99 AND 00 CHEVROLET SILVERADOS DO NOT HAVE A PROBLEM WITH THIER NEW ENGINES. I KNOW OF NUMEROUS OTHER OWNERS WHO HAVE THIS PROBLEM WHICH CHEVROLET ACKNOWLEDGES AS A NORMAL SOUND. I HAVE BEEN TOLD BY THE DEALER THAT THE TRUCK CAN NOT BE FIXED BECAUSE THE NEW ONES MAKE THE SAME NOISE. I HAVE DRIVEN OTHER COMPRIABLE TRUCKS AND THEY DO NOT HAVE THE ENGINE PING/KNOCK. THE DEALER ALSO SAID THAT THE NOISE WILL EVENTUALLY GO AWAY, BUT I HAVE SEEN TRUCKS WITH 19000 WITH THE NOISE CONTINUING. THIS PROBLEM COULD INCREASE EMMISIONS IF IT IS INDEED A PING/KNOCK. IF THIS PROBLEM PERSISTS WITH NO FIX FROM CHEVROLET, I COULD HAVE ENGINGE DAMAGE CAUSED BY THE PING/KNOCK THAT WILL NOT BE COVERED BY THE WARRANTY. THANK YOU FOR YOUR TIME.
