MY 2006 CHEVY SILVERADO 1500 EXTENDED CAB HAS JUST OVER 116000 MILES ON IT AND THERE IS A LOUD KNOCKING COMING FROM THE #2 LIFTER. IT ONLY DOES IT WHEN IT GETS WARM OR GIVEN GAS ON TAKE OFF.. IT DOESN'T DO IT WHEN IDLING. I KNOW 2 OTHER PEOPLE THAT HAVE THE SAME YEAR AND MODEL TRUCK WITH THE SAME ISSUE. I LOVE MY TRUCK AND I TAKE EXTREMELY GOOD CARE OF IT BUT TO HAVE IT FIXED, MY MECHANIC SAID A NEW ENGINE IS BETTER AND CHEAPER THAN REBUILDING IT. TOTAL COST OF $6000 . AND THE PASSENGER SIDE DOOR LEAKS INSIDE THE TRUCK WHEN IT RAINS , BETWEEN THE FRONT AND REAR DOOR. THERE SHOULD BE SOMETHING THAT CHEVROLET CAN DO TO FIX THIS PROBLEM. I HAVE ALWAYS LOVED CHEVY, BUT I'M STARTING TO GET VERY DISAPPOINTED WITH THEM AND THE QUALITY BEING MADE AND SOLD FOR SUCH HIGH AMOUNTS OF CASH..

MY VEHICLE IS BURNING MORE OIL THAN NORMAL. I PURCHASED THE PICKUP ON AUG 10, 2016 AND THE DAY PRIOR THE DEALERSHIP HAD JUST DONE A FRESH OIL CHANGE. I DOUBLE CHECKED THE NEW OIL BEFORE DRIVING FROM THE LOT AND SEEN THE OIL WAS NEW AND FRESH. A MONTH AND A HALF LATER MY HUSBAND IS DRIVING HOME FROM CAPE MAY NEW JERSEY WHICH IS A 6 HOUR DRIVE AND JUST AFTER FILLING UP HIS GAS TANK AND DRIVING HOME...THE VEHICLE STARTS SMOKING PROFUSELY. HE HAD TO ADD 5 QUARTS OF OIL TO THE VEHICLE BECAUSE IT LOOKED AS THOUGH THE OIL WAS COMPLETELY DRAINED FROM THE ENGINE.

THE AIR BAG SERVICE LIGHT AND IS LIT AS WELL AS THE SERVICE CENTER SAYING IT NEEDS SERVICE, ALSO HAS THE SAME BRAKE PROBLEMS THE 2007 AND UP SILVERADOS WHERE RECALLED FOR WITH THE FAILURE OF THE FRONT ABS SENSORS. THE ABS PROBLEM COULD CAUSE AN ACCIDENT AT LOW SPEED BECAUSE EVERYTIME YOU STOP THE ABS SYSTEM ACTIVATES AND PULSES UNTIL STOPPED AT 15 TO 20 MPH AND INCREASES STOPPING DISTANCE. THE AIR BAG LIGHT IS BECAUSE OF A SENSOR FAILURE IN THE FRONT END AREA AND REQUIRES REPLACEMENT. FROM WHAT I READ ON THE INTERNET THESE ARE WELL KNOWN SAFETY ISSUES WITH THE MODEL TRUCKS. THE OTHER PROBLEMS WITH THE PREMATURE FAILURE OF BRAKE LINES THAT HAVE CORRODED, AND THE CHECK ENGINE LIGHT BEING ON FOR THE EVER WELL KNOWN PROBLEM OF THE VACUUM SOLENOID NEAR THE FULL TANK. THESE ARE CONSTANT PROBLEMS WITH THIS YR AND OTHER MODELS AT GM. THEY SHOULD BE RECALLED. *TR

ROTTEN BRAKE LINES. I LOOKED AT THE BRAKE LINES WHILE CHANGING MY OIL. MY TRUCK HAS 47K ON IT. I CALLED GM. THEY TOLD ME THAT I HAD TO BRING IT TO A DEALER. I DID. THEY CONFIRMED THAT THE BRAKE LINES ARE BAD AND NEED TO BE REPLACED. $1500 ALSO THE TRANSMISSION COOLING LINES ARE LEAKING. I HAVE BEEN THROUGH ALMOST ALL OF THE BRAKE PROBLEMS LISTED ON THIS WEB CITE. ABS LIGHT COMES ON, TWICE, 2ND TIME I REPLACED THE LEFT HUB BEARING ASSEMBLY. THE 1ST TIME THE DEALER REPLACED THE FRONT ABS SENSORS. AIR BAG LIGHT COMES ON, I REPLACED A BAD FRONT AIR BAG SENSOR, RIGHT SIDE. THIS TRUCK IS TURNING INTO A MONEY PIT!!!!! THIS NEW (ROTTEN LINES) ISSUE IS A SAFETY ISSUE AS WAS THE ABS ISSUE. GM NEEDS TO DO A FULL RECALL AND REPLACE THE BRAKE LINES BEFORE SOMEONE GETS KILLED. *TR

WHILE DRIVING MY TRUCK DOWN THE FREEWAY, THE ENGINE LIGHT SUDDENLY CAME ON AND A WARNING APPEARED ON THE DASHBOARD STATING "REDUCED ENGINE POWER" AND THE TRUCK SHUT ITSELF DOWN TO 10 MILES AN HOUR IN SECONDS. I HAD VEHICLES COMING UP BEHIND ME TRAVELING AT 60 MPH AND HIGHER THAT NEARLY HIT ME FROM BEHIND. EVEN IF I FLOORED THE GAS PEDAL THE TRUCK WOULD NOT SPEED UP MAKING IT EXTREMELY DIFFICULT TO GET OUT OF THE WAY OF ONCOMING TRAFFIC. THE LOCAL CHEVY DEALERSHIP HAD MY TRUCK 2 DAYS AND CHARGED ME $400.00 FOR AN EMISSIONS PART. I PICKED MY TRUCK UP ON THURSDAY EVENING, JAN. 20, 2011, AND IT BROKEN DOWN THE VERY NEXT MORNING WITH THE SAME ISSUE. I TOOK IT RIGHT BACK OVER THERE AND THEY TOLD ME TO RETURN IT ON MONDAY JAN. 24 WHICH I DID. THEY RETURNED THE TRUCK TO ME ON WEDS. JAN. 26, AND SAID THEY COULDN'T FIGURE OUT THE PROBLEM BUT MAY HAVE BEEN A LOOSE WIRE. THE TRUCK BROKE DOWN WITH THE SAME ISSUE AGAIN ON FEB 14. THE DEALERSHIP HAD IT ANOTHER 3 DAYS AND SAID THEY SOLDERED SOME CONNECTIONS. AGAIN ON MARCH 10, MY TRUCK BROKE DOWN AGAIN, SAME ISSUE. THEY HAD MY TRUCK UNTIL MARCH 14, AND AGAIN CHARGED ME FOR REPLACING THE WIRING HARNESS AND THROTTLE BODY. I PICKED MY TRUCK UP AT 6 PM MON MARCH 14 AND IT ALREADY BROKE DOWN AGAIN THIS MORNING MARCH 16, SAME ISSUE. ON TWO OCCASIONS NOW I HAVE HAD MY KIDS IN THE BACK SEAT, DRIVING ON THE FREEWAY WHEN THE ENGINE DECIDES TO SHUT ITSELF DOWN. NO ONE AT CHEVY SEEMS TO CARE IF WE ARE INJURED OR KILLED WHEN WE ARE HIT DUE TO THIS DEFECTIVE TRUCK. I AM NOT THE ONLY CHEVY OWNER REPORTING THIS PROBLEM. NOT ONLY ARE THERE COMPLAINTS ALL OVER THE INTERNET, BUT THE DEALERSHIP HAD ANOTHER TRUCK IN AT THE SAME TIME AS MINE AT THE MARCH 10 VISIT, WITH THE EXACT SAME ISSUE AND IT HAD ALREADY BEEN IN MULTIPLE TIMES FOR THE SAME ISSUE AS WELL.

BOUGHT IT NEW, REPLACED BATTERY IN 6 MONTHS, HAVE REPLACED HEADLIGHTS AND BACK LIGHTS TWICE, THE TRUCK SHIMMIES WHILE BRAKING, ENGINE LIGHT KEEPS COMING ON, ENGINE HEATS UP WHILE IDLING, SHALL I CONTINUE? I HAVE PURCHASED GMC PRIOR TO THIS CHEVROLET. I DO LIKE THE PRODUCT BUT GMC HAS INCREDIBLE CUSTOMER SERVICE FOR THESE TYPES OF PROBLEMS.
