2002 CHEVROLET SILVERADO Engine And Engine Coolingengine Problems

TL*THE CONTACT OWNS A 2002 CHEVROLET SILVERADO. WHILE DRIVING VARIOUS SPEEDS, THE CHECK ENGINE LIGHT ILLUMINATED ON THE INSTRUMENT PANEL AND THE VEHICLE WOULD STALL. AN INDEPENDENT MECHANIC COULD NOT DUPLICATE THE FAILURES; THEREFORE, THE ISSUES CONTINUED TO PERSIST. THE GM DEALER DISCOVERED THAT THE CRANKSHAFT SENSOR WAS FAULTY. THERE WERE NO REPAIRS MADE TO THE VEHICLE. AN INVESTIGATION WAS OPENED IN REGARDS TO THE CRANKSHAFT SENSOR FAILURES (NHTSA ACTION NUMBER PE06016), BUT THERE WERE NO RECALLS. THE FAILURE AND CURRENT MILEAGES WERE LESS THAN 77,000. UPDATED 6/22/09 *CN THE CONSUMER STATED THE ENGINE SHUT DOWN ON HIM WHILD DRIVING ON THE HIGHWAY. UPDATED 06/25/09.*JB

DT*: THE CONTACT STATED THE ABS ENGAGES AT LOW SPEEDS OF 20 MPH AND BELOW. AS A RESULT, THE STOPPING DISTANCE WAS INCREASED. THERE IS A NHTSA RECALL, # 05V379000, REGARDING THE ABS. THE VEHICLE HAS THE SAME PROBLEMS AS INDICATED IN THE RECALL; HOWEVER IT IS NOT INCLUDED IN THE RECALL BECAUSE OF THE VIN. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION. THE DEALER CLEANED THE WHEEL SPEED SENSOR, REPLACED THE PADS AND ROTORS. HOWEVER, THOSE REPLACEMENTS DID NOT CORRECT THE PROBLEM. ADDITIONALLY, A KNOCKING NOISE WAS HEARD IN THE ENGINE. THE DEALER INSPECTED THE ENGINE ALTHOUGH, NO REPAIRS WERE MADE. THE PASSENGER SIE WINDOW WAS INOPERATIVE. UPDATED 03/28/06. *JB

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...

CLUNK TYPE FEELING IN STEERING WHEEL ON TURNS AND WHEN HITTING BUMPS. ENGINE KNOCK ON COLD START. *BF ENGINE WAS NOISY WHEN STARTED AFTER HAVING SAT OVER NIGHT *TC *JB

THE CONSUMER STATED WATER SEEPED INTO THE ENGINE DISTRIBUTOR WITHOUT WARNING. AS A RESULT THE ENGINE FAILED. *JB THE CONSUMER WROTE ABOUT TWO VEHICLES, THE SECOND VIN #[XXX] SAME MAKE AND MODEL.

KNOCK IN MOTOR OF 2002 CHEVY SILVERADO, 5.3 MOTOR WITH 30,000 MILES. DEALER SAYS KNOCK IS NORMAL. CHEVROLET SENT LETTER TO ME STATING THEY WILL PROVIDE SERVICE COVERAGE FOR ENGINE TILL 100,000 MILES, BUT KNOCK IS NORMAL. THEY CLAIM THAT THIS IS FULL COVERAGE PARTS AND LABOR BUT WON'T SEND LETTER STATING FULL COVERAGE ONLY THAT THEY ARE PLEASED TO PROVIDE COVERAGE. SOUNDS FISHY! THE KNOCK CONTINUES TO LAST LONGER ON COLD START AND GETS LOUDER BY THE WEEK.*AK

ENGINE KNOCK.. HOT & COLD. SOUNDS LIKE LIFTER NOISE, GM SAYS IT'S "NORMAL" . OVER 30 YEARS AS A MECHANIC, I KNOW THERE'S NO SUCH THING AS A NORMAL KNOCK. AFTER RESEARCHING THIS ISSUE, I FIND THERE ARE ABOUT 800,000 VEHICLE INVOLVED. GM NEEDS TO FIX THESE VEHICLES. GM SERVICE BULLETINS REFER TO THIS AS PISTON SLAP. ANY SLAP, SCUFF, OR ABNORMAL NOISE IN A CYLINDER IS DETRIMENTAL TO THE METALS. *JB

2002 SILVERADO TAILGATE LATCH QUIT WORKING, ALSO 6.0L ENGINE SLAPPED DURING START UP, SOUNDED BAD.*AK

WHILE DRIVING A "PINGING" NOISE COULD BE HEARD COMING FROM THE ENGINE. THE DEALER DETERMINED THAT CARBON BUILD-UP ON TOP OF THE PISTONS WAS THE CAUSE OF THE PROBLEM. PLEASE PROVIDE ANY ADDITIONAL INFORMATION. *NLM THE OIL PUMP WAS REPLACED BUT THE NOISE WAS STILL PRESENT. CONSUMER CONCERNED THAT THE ENGINE WILL FAIL IF THIS IS A LUBRICATION PROBLEM. HE BROTHER HAS THE SAME MAKE, MODEL AND EXPERIENCED THE SAME DEFECT. VEHICLE WAS REPAIRED BY THE SAME DEALERSHIP AND PROBLEM CEASED. *PH

WHEN MOTOR STARTS UP SOUND LIKE ROD ARE COMING THRU THE BLOCK THIS STARTED MORE THEN A YEAR AGO REG. WITH GM AND RECEIVED LETTER ON THE PROBLEM IT HOW A LOT WORST AND STATES I MUST LIVE WITH ITS. IT NOW KNOCKS FOR 4 TO 5 MIN AFTER STARTING. YOU SHOULD NOT HAVE THIS KIND OF PROBLEM ON A 39000 $ VEC. HELP. *LA

THE ENGINE CONSUMED AN EXCESSIVE AMOUNT OF OIL. THE DEALER HAD INSPECTED THE VEHICLE SEVERAL TIMES, AND COULD NOT DUPLICATE OR CORRECT THE PROBLEM. *AK IF ENGINE STOPS RUNNING BECAUSE OF LACK OF OIL, THE STEERING AND BRAKES WOULD LOCK RESULTING IN A COLLISION. *PH *JB

CONSUMER STATES THAT WHILE DRIVING THE VEHICLE THE CHECK ENGINE LIGHT WOULD COME ON AND STAY ON. DEALER NOTIFIED.*AK

CONSUMER STATES THAT WHILE DRIVING AT ANY SPEED AND WITH NO WARNING THE VEHICLE WILL SHUT OFF, CAUSING CONSUMER TO PULL OVER, AND IT WILL BE HARD TO GET THE VEHICLE BACK STARTED.DEALER NOTIFIED.*AK

THE VEHICLES OIL PUMP FAILED AT 36K MILES AND CAUSED DAMAGE TO THE ENGINE. *NLM

THE CONSUMER HAD TO REPLACE SEVERAL MAJOR VEHICLE COMPONENTS SINCE THE VEHICLE WAS PURCHASED, INCLUDING THE ENGINE WHICH FAILED AT 36,700 MILES. *NLM

WHEN THE VEHICLE WAS FIRST STARTED, THE ENGINE HAD A KNOCKING NOISE.*JB

MY 2002 CHEV TRUCK KNOCKS WHEN I START THE ENGINE. (6.0) MOST CHEV TRUCKS DO THIS. THE DEALER TOLD ME IT WAS NORMAL. I WOULD LIKE TO HAVE THEM AROUND WHEN I TRY AND SELL THE TRUCK. THE NOISE CAME AFTER THE TRUCK WAS ONLY 4 MONTHS OLD. IT HAS BEEN GETTING WORSE AND WORSE. MY RESALE VALUE IS GOING TO SUCK. IF IT IS NORMAL, I TOLD THEM THEY SHOULD ADVERTISE IT IN THEIR TV COMMERCIAL. CHEV TRUCKS, LIKE A ROCK, AND SOUND LIKE A ROCK SHAKING IN A TIN CAN. *JB

THE VEHICLE CAUGHT FIRE UNDER THE HOOD. *JB WIRING FROM ELECTRIC FUEL PUMP IN GAS TANK CAUGHT FIRE AND BURNED TWO HOLES IN THE TOP OF THE GAS TANK. *TS

THE VEHICLE MADE A NOISE, THE PROBLEM WAS DIAGNOSED AS A SLAPPED PISTON.*JB

WHEN STARTING THE VEHICLE, THERE IS A KNOCKING NOISE COMING FROM THE ENGINE CAUSED BY PISTON SLAP, IF NOT FIXED, THIS COULD CAUSE PISTON TO BREAK AND DAMAGE THE ENGINE.*AK CONSUMER IS CONCERNED THAT THE ENGINE WILL FAIL IN THE FUTURE. *YH
