NHTSA Complaint #10143468 — 2002 CHEVROLET SILVERADO

COLD ENGINE START-UP KNOCK. I OWN A 2002 SILVERADO Z71 WITH THE 4.8 ENGINE. THE ENGINE HAS HAD COLD START-UP KNOCK SINCE I HAVE OWNED IT. I HAVE ASKED DEALERS ABOUT IT AND HAVE BEEN TOLD IT IS NORMAL. I BUILD ENGINES FOR AND OWN TO DRAG CARS. ONE IS AN ET FOOTBRAKE CAR WITH A MILD 350 CI SMALL BLOCK CHEVY. THE OTHER IS A 48 FIAT ALTERED WITH A 434 CI SMALL BLOCK CHEVY STROKER. BOTH HAVE FORGED PISTONS AND NEITHER HAS THE COLD PISTON NOISE THAT THIS BONE STOCK 4.8 HAS. I CURRENTLY HAVE 39,139 MILES ON MY TRUCK AND WANT IT TO LAST AS LONG AS POSSIBLE. UNDER THE CURRENT CIRCUMSTANCES, I DON'T THINK IT WILL LAST MUCH LONGER BEFORE IT CRACKS A PISTON SKIRT OR SEVERELY DAMAGES THE CYLINDER WALLS. IT IS MY INTENTION TO CONTACT CHEVROLET IN THE NEXT COUPLE OF DAYS BUT AFTER READING THE COMPLAINTS ON THIS SITE, I AM PREPARED TO BE TOLD THE SAME AS THE DEALER TOLD ME. I AM ALSO LOOKING INTO THE CLASS ACTION SUIT APPROACH TO GET A REMEDIE TO THE PROBLEM. ANOTHER ISSUE IS THE BRAKES. THE TRUCK HAS 4 WHEEL DISK AND STOPS LIKE IT HAS FOUR WHEEL DRUMS WITHOUT POWER?? I OWNED A 97 SIVLVERADO THAT HAD BRAKES THAT WORKED THE SAME. YOU WOULD THINK THAT A TRUCK THAT COST 30,000 DOLLARS WOULD BE A LITTLE BETTER CONSTRUCTED. *NM
