NHTSA Complaint #762015 — 2000 CHEVROLET SILVERADO

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
