2001 CHEVROLET SILVERADO Engine And Engine Coolingenginegasoline Problems

VEHICLE STALLS WHILE DRIVING AT ALL SPEEDS AS POWER STEERING AND BRAKES GO OUT. OFTEN WILL NOT START BACK UP RIGHT AWAY. *NM

MY COMPLAINT IS REGARDING A KNOCKING NOISE COMING FROM MY ENGINE OF MY 2001 CHEVROLET SILVERADO. IT SOUNDS LIKE THE PISTONS ARE HITTING THE CYLINDER WALL OF MY ENGINE. I DO HAVE 140,000 MILES ON IT BUT THE PROBLEM STARTED ABOUT 3-4 YEARS AGO. THE REASON I DIDN'T COMPLAIN BECAUSE DEALERS HAVE ALWAYS SAID THAT IT WAS NORMAL. BUT FROM ONLINE FORUMS I HEAR THAT I AM NOT THE ONLY ONE HAVING THIS PROBLEM. MY ENGINE HAS LOST A SIGNIFICANT AMOUNT OF POWER AND I THINK THAT IS THE REASON WHY. *JB

CLUNK , SQUEAK, OR SQUAWK WHEN COMING TO A STOP AND STARTING UP.*AK

THROTTLE PEDAL STICKS AT IDLE, WHEN I PUSH ON THE THROTTLE TRUCK JUMPS FORWARD. THIS STARTED ABOUT 55,000 MILES AND NOW HAVE 63,000. THE PROBLEM HAPPENS DAILY, BUT NOT ALL THE TIME. *JB

I WAS SEEING A LOW COOLANT WARNING LIGHT THAT WAS INTERMITTENT. I ADDED DISTILLED WATER TO THE COOLANT SYSTEM SEVERAL TIME IN THE AMOUNT FOR A TOTAL OF ABOUT A HALF GALLON. I SEARCHED FOR A LEAK IN THE COOLANT HOSES BUT COULD NOT FIND A LEAK. I CHECKED THE DIP STICK TO SEE IF THE OIL WAS CLOUDY OR HAD BUBBLES BUT DID NOT SEE ANY. (I USE MOBIL 1 SYNTHETIC OIL). AFTER ABOUT A WEEK THE COOLANT WARNING LIGHT CAME ON AT A HIGHER FREQUENCY SO I TOOK THE TRUCK TO THE DEALER. THEY DIAGNOSED THE PROBLEM AS HEAD GASKET LEAKS AND POSSIBLE WATER PUMP GASKET LEAKS. THE BILL FOR THE REPAIR WAS $1200. I WAS LATER TOLD THE HEAD BOLTS LOST TORQUE AND "STRETCHED". THE HEADS HAD NEVER BEEN REMOVED AND THE TRUCK HAD NEVER REQUIRED ANY REPAIRS EXCEPT FOR THE BROKEN TAIL GATE CABLES WHICH CAUSED...

4.3 LITER V6 ENGINE W/STANDARD TRANS. - BUTTERFLY VALVE IN ENGINE AIR INTAKE THROTTLE BODY HAS SHALLOW CUP RIVETED TO ENGINE SIDE (UNDERSIDE) OF FLAT BUTTERFLY VALVE. THIS SHALLOW METAL CUP IS TEARING LOOSE, WITH OUTSIDE EDGE BENDING DOWNWARD AND AWAY FROM FLAT BUTTERFLY VALVE TO APPROX. 30 DEGREES. THE BEND IS AT THE RIVETED JOINTS WHERE THE CUP IS ANCHORED TO THE FLAT BUTTERFLY VALVE. THE CUP METAL HAS TWO TEARS IN THE METAL WHERE RIVETS HAVE HELD FAST. VEHICLE HAS 40,000 MILES AND IS IN GOOD CONDITION, DRIVEN ON CITY STREETS ONLY. DEALER SAYS WILL FIX FREE IF CHEVROLET SERVICE CENTER GIVES OK, AND CHEVROLET SERVICE CENTER SAYS DEALER MUST APPROVE. PROBLEM HAS POTENTIAL FOR CATASTROPHIC ENGINE DAMAGE AND/OR ENGINE FIRE. PLEASE HELP.*JB

ENGINE NOISE THAT SOUNDS LIKE LIFTER. PH

WHEN HAULING HEAVY LOADS, CONSUMER STATES THE TRUCK CONSUMES MORE OIL THAN NORMAL. CONSUMER FEELS THIS MAY BE A DEFFECT. PLEASE PROVIDE ANY FURTHER INFORMATION. MR

WHILE TRAVELING AT 60 MPH THE VEHICLE ENGINE SUDDENLY SHUT OFF. CONSUMER STATES WAS ABLE TO RESTART. TOOK TO CHEVROLET AND THEY ARE NOT AWARE OF ANY PROBLEM WITH ENGINES STALLING. PLEASE PROVIDE ANY FURTHER INFORMATION. MR

THE CONSUMER STATES THAT THERE IS A CLATTERING NOISE DURING ACCELERATION/PINGING, UP INCLINES AND UNDER LOAD WEIGHT. AND FOUND EXCESSIVE VALVE CLATTERING ON ACCELERATION AND DECARBONIZED THE VALVES, BUT WERE UNABLE TO RESOLVE THE PROBLEM. (THE VEHICLE WAS RELEASED WITH THE KNOWLEDGE THAT THE PINGING STILL OCCURED) THE CONSUMER IS GIVING CHEVROLET THE OPPURTUNITY TO RESOLVE THE PROBLEM IN A TIMELY MANNER, AND IF THESE PROBLEMS ARE NOT REPAIRABLE, THEN HE IS EXPECTING A REFUND OF THE PURCHASE PRICE WITH INTEREST. *SCC

THE ENGINE STARTED KNOCKING UPON COLD START UP AT APPROX. EIGHT THOUSAND MILES, AND A PROBLEM STARTED WITH A ENGINE PINGING NOISE(VALVE CLATTER) AT THE SAME MILEAGE. THE PROBLEMS WERE REPORTED TO THE DEALER SEVERAL TIMES IN WHICH NO ATTEMPT FOR CORRECTION WAS MADE ON REPAIRING THE ENGINE KNOCK. THE VALVE CLATTER PROBLEM HAS BEEN WORKED ON MORE THAN THREE TIMES WITH NO SOLUTION. NOW THE PROBLEM IS DEEMED UNREPAIRABLE OR AS THE DEALER STATES "NORMAL" AS MY REPLY IS THAT THE TRUCK DID NOT MAKE ANY NOISE UNTILL 8,000 MILES, IF THE NOISE IS NORMAL WHY DID IT TAKE 8,OOO MILES FOR THE PROBLEM TO ARRISE. AT THE PRESENT TIME THE ENGINE KNOCKS ON BOTH HOT AND COLD START AND VALVE CLATTER IS EXPERIENCED UPON ACCELERATION, CONSTANT SPEEDS, AND IS THE WORST WHEN TRYING TO TOW A TRAILER OF LESS THAN 30% OF VEHICLES MAX GVWR. THE SECOND PROBLEM...

ENGINE IS USING BETWEEN 4 AND 7 QTS OF OIL BETWEEN OIL CHANGES. GENERAL MOTORS DESIGNED A NEW PCV VALVE IN HOPES OF SOLVING THIS OIL USAGE PROBLEM. IT HAS NOT HELPED ONE BIT. THE TRUCK IS NOT LEAKING THE OIL OUT ON THE GROUND. THERE IS NO BLUE SMOKE COMING FROM TAILPIPE. THIS TO ME SEEMS TO BE AIR POLLUTION. I WAS TOLD IT WAS A NATION WIDE PROBLEM NOT JUST MINE. THE VEHICLE IS DOING THIS AT NORMAL HIGHWAY DRIVING SPEEDS OF 55 TO 70 MPH. DT

CONSUMER STATES THAT THE VEHICLE WILL START TO SURGE WHILE THE CONSUMER IS DRIVING, THERE IS ALSO A KNOCKING NOISE IN THE ENGINE. CONTACTED DEALER AND THEY CANNOT FIND THE PROBLEM. NLM

KNOCKING NOISE FROM BEGINNING-DEALER STATED "COLD STARTUP"-WRONG! MANUFACTURER SAID NOT DETRIMENTAL TO ENGINE-THEY HAD TO REPLACE MY ENGINE @ 25,000 MILES-STILL KNOCKING. GRINDING IN REAR END AT TAKE OFF-HAD TO REPLACE MY DRIVESHAFT-STILL GRINDING. MY TRUCK HAS BEEN IN 4 TIMES FOR ENGINE KNOCKING AND 5 TIMES FOR REAR END GRINDING. I'M NOW FIGHTING WITH GM AND BBB FOR A BUY BACK-MY TRUCK QUALIFIES UNDER THE LEMON LAW-33 TOTAL DAYS IN SHOP SO FAR. WILL NEVER BUY ANOTHER!!!*AK

CONSUMER STATES THAT THE CHECK ENGINE LIGHT IS ON AND THE ENGINE IS LEAKING DIESEL FUEL RESULTING STRONG DIESEL FUMES. *TT

THE ENGINE KNOCKS FOR APPROXIMATELY 10 SECONDS UPON STARTING THE TRUCK.*AK

VEHICLE MADE "CLICKING" NOISE WHEN STARTED DUE TO OIL PUMP FAILURE. *AK

ENGINE LIGHT STAYS ON ALL THE TIME. CONSUMER FEELS THERE MAY BE A SERIOUS PROBLEM WITH ENGINE BECAUSE OIL NEEDS TO BE CHANGED EVERY 7000 MILES. PLEASE PROVIDE ANY FURTHER INFORMATION.*AK

CONSUMER STATES THERE IS SOMETHING WRONG WITH THE ENGINE. THE OIL PRESSURE WOULD NOT REMAIN CONSTANT, INSTEAD IT BOUNCED UP AND DOWN. *YD

WHILE DRIVING, SEAT BELT BECOMES VERY TIGHT, GIVING A FEELING OF CLOSTRAPHOBIA. TOOK VEHICLE TO DEALER.*AK CONSUMER STATED TIRES VIBRATED AT A SPEED OF 45-50, CONSUMER WAS INFORMED THAT THE TIRES WERE OUT OF ROUND, ALSO WHEN THE VEHICLE IS DRIVEN FOR AWHILE, IT SEEMS TO MISS SPEEDS, WHEN MAKING HARD TURNS IN EITHER DIRECTION, THERE IS A WHINING NOISE COMING FROM THE STEERING, AND IN COOL WEATHER THE STEERING IS HARD TO TURN, ALSO THE SERVICE ENGINE SOON LIGHT ILLUMINATED AND THE VEHICLE WOULD STALL WHILE DRIVING.*JB

WHILE DRIVING, CONSUMER HEARD A NOISE. WHEN VEHICLE COMES TO A COMPLETE STOP IT VIBRATES. TOOK TO DEALERSHIP AND MOTOR WAS OUT OF BALANCE. *AK *YD

A VERY LOUD KNOCKING NOISE IS COMING FROM THE MOTOR, WE HAVE HAD THE LIFTERS REPLACED, BUT IT STILL HAS FAILED TO CORRECT THE PROBLEM WE HAVE CONTACTED THE BBB ABOUT THIS PROBLEM WE ARE WAITING TO SEE WHERE WE GO FROM HERE.*AK

ENGINE STOPS INSTANTANEOUSLY WITHOUT WARNING. EXTREME SAFETY PROBLEM IN HEAVY TRAFFIC AS POWER STEERING IS LOST. CRANKSHAFT POSITION SENSOR HAS FAILED IN BOTH INSTANCES.

WHEN STARTING VEHICLE, WHETHER IT'S COLD OR HOT, VEHICLE WILL MAKE A LOUD NOISE THAT COMES FROM ENGINE. NOISE GETS WORSE WHEN GETTING ON THE HIGHWAY. *AK DOOR WINDOWS WERE LOOSE. DEALER STATES THE ENGINE NOISE IS NORMAL. *JB

VEHICLE WAS CONSUMING OIL. ENGINE WAS MAKING TAPPING NOISES. GAUAGE WOULD ALWAYS BE UNDER NORMAL LEVEL. NO OIL LEAKAGE WAS FOUND ON THE GROUND. DEALER WOULD NOT HONOR MANUFACTURER'S WARRANTY BECAUSE IT WAS NORMAL FOR VEHICLE TO BURN A QUART OF OIL. ONLY IF IT BURNED A QUART OF OIL WOULD MECHANIC INSPECT VEHICLE. *AK

THERE IS A LOUD NOISE COMING FROM ENIGNE. HAS TAKEN VEHICLE TO DEALER, BUT DEALER CANNOT FIND CAUSE OF PROBLEM. *AK

TIRES "CUPPED" BEFORE 8000 MILE ROTATION, TRANSMISSION- FEELS LIKE CLUTCH IS SLIPPING, HAS TIMES IN NUETRAL FROM A STOP THEN SLAMS INTO GEAR... MOTOR SOUNDS LIKE A DIESEL AT START UP QUIETS SOME, YET ALL THIS IS SUPPOSE TO BE "NORMAL". *AK (TIRESIZE: 235/75/R16)

I PURCHASED MY VEHICLE AND 1 WEEK AFTER PURCHASE THE ENGINE BEGAN MAKING A KNOCKING NOISE WHICH PROCEEDED TO GET LOUDER. I PHONED MY DEALERSHIP AND THEY MADE AN APPT TO BRING IN THE VEHICLE FOR INSPECTION. I WAS TOLD AT THAT TIME THAT THE VORTEC ENGINE MADE THAT SOUND AND THERE WAS NOTHING THEY COULD DO. I DISAGREED AS IT DIDNT KNOCK WHEN I PURCHASED IT. THEY DID A TOP ENGINE CLEAN AND RETURNED THE VEHICLE. I DROVE IT TO WYOMING AND THE SAME DAY I PICKED IT UP IT WAS KNOCKING AND MISSING. I PHONED THE DEALERSHIP AND THEY SAID TO BRING IT IN WHEN I GOT HOME AND GAVE ME GM CARES NUMBER IN CASE IT BROKE DOWN. I TOOK THE VEHICLE BACK IN AND THEY HAVE NOW HAD IT FOR 16 DAYS. NOTHING HAS BEEN DONE TO REPAIR IT . I PHONED GM THEY SAID 1...

VEHICLE HAS STALLED NUMEROUS TIMES BOTH WHILE DRIVING AND WHILE STOPPED AT A LIGHT, BUT PROBLEM OCCURS INTERMITTENTLY. AFTER SEVERAL TRIES THE VEHICLE WILL START AGAIN. DEALER UNABLE TO RECREATE PROBLEM NO SOLUTION PROVIDED.*AK

ON 3 OF THE ONLY 4 OCCASIONS I HAVE HAD TO DRIVE THIS VEHICLE AT 70 MPH FOR ANY EXTENDED PERIOD WHEN OUTSIDE TEMPERATURES EXCEEDED 90, THE FOLLOWING SYMPTOMS HAVE MANIFESTED: LOUD ENGINE KNOCK SUFFICIENT TO SHAKE VEHICLE AND DISCHARGE OF LARGE CLOUD OF GRAY (NOT THE BLACK AS IS TYPICAL FOR A DIESEL) SMOKE. NUMEROUS CARS HAVE DRIVEN OFF THE ROAD BEHIND ME TO AVOID THE CLOUD OF SMOKE THAT OBSCURES THEIR VISION (AND POSSIBLY TO AVOID PARTS FROM A MOTOR THEY MAY THINK HAS BLOWN UP). VEHICLE IS PRESENTLY AT KING CHEVROLET, TYLER, TEXAS FOR 2ND TIME (NOT SELLING DEALER) AND HAD BEEN AT ONE OTHER DEALER; LEWIS CHEVROLET, CANTON,TEXAS. PROBLEM HAS NOT BEEN DIAGNOSED. DEALERS SAY THAT GM TECHNICIANS SAY PROBLEM IS UNIQUE - NO OTHER OWNERS HAVE REPORTED THIS PROBLEM. PROBLEM HAS BEEN REPORTED TO GM WHICH HAS ASSIGNED THE COMPLAINT FILE #4913340. AT TIME OF...

THE ENGINE KNOCKS AT STARTUP WHEN ENGINE IS COLD. I CONTACTED GM AND I HAVE GONE TO A LOCAL DEALER ABOUT THE PROBLEM (NOT LAWSON CHEVROLET WHICH WAS THE DEALER I PURCHASED THE VEHICLE FROM). NEITHER GENERAL MOTORS OR THE LOCAL DEALER WHERE OF ANY HELP. BASICALLY I HAVE BEEN TOLD THE KNOCKING AT STARTUP IS NORMAL.

CONTACTED DEALER;SAID TSB WILL BE ISSUED;I AM MAKING NHTSA AWARE OF PROBLEM TO KEEP CONSUMERS INFORMED OF ANY RECALLS REMEADIES OR REPAIRS CONSERNING THIS ENGINE NOISE. *AK
