IT'S TERRIFYING. SOMETIMES IT WON'T START OR DO ANYTHING. BUT IF I JIGGLE IT THEN IT WILL START. THIS HAS HAPPENED MULTIPLE TIMES WITH MULTIPLE DRIVERS. I HAD IT DIAGNOSED AND DID SOME QUICK ONLINE SEARCHES AND THIS SEEMS TO BE AN ISSUE WITH THESE TRUCKS.

THE ENGINE IN THE CHEVY VEHICLES FROM 2007-2015 ALL HAVE HIGH OIL CONSUMPTION AND REQUIRE ENGINE REPLACEMENT ANYWHERE AFTER 500 MILES. MY CAR WAS PURCHASED NEW AND NEEDS A NEW ENGINE A LITTLE OVER 5 YEARS LATER?
Engine, Apr 24, 2017
THE ENGINE IN THIS VEHICLE BURNS/VAPORIZES OIL AT A RAPID PACE. I HAVE A 2011, 114K MILES, AND HAD TO REPLACE THE PISTONS TO THE TUNE OF $5400 - CHEVROLET WOULD NOT HELP WITH COSTS. 6 YR OLD VEHICLE, JUST OVER 100K MILES AND HAVE TO REPLACE THE PISTONS.. I HAD KEPT UP ALL SCHEDULED MAINTENANCE AT THE DEALERSHIP. HAVE A "WARRANTY FOREVER" , LIFE TIME POWER TRAIN WARRANTY, AND DENIED MY CLAIM BECAUSE IT WAS DUE TO 'WEAR AND TEAR'. HOW CAN MY 6 YR OLD, 114K MILE VEHICLES ESSENTIALLY NEED A NEW ENGINE? CHEVROLET SHOULD BE DISGUSTED WITH THEMSELVES. I KNOW MANY OTHERS WITH SIMILAR YEAR, SAME ENGINE AND HAVE THE SAME PROBLEMS. THIS PROBLEM SHOULD BE INVESTIGATED. I HAVE NOT FAITH IN THE CHEVROLET PRODUCT ANYMORE.

THE FUSE RELAY BLOCK ON MY 2011 CHEVROLET SILVERADO 1500 WITH ONLY 56,000 MILES NEARLY CAUGHT FIRE WHEN THE REAR WINDOW DEFROSTER AND HEATED MIRRORS WOULD NOT TURN OFF EVEN WITH THE KEY REMOVED. THE PROBLEM WAS TRACED TO A BAD GROUND ON CIRCUIT G200, THIS IS PART OF THE SWITCH CIRCUIT THAT CONTROLS THE MIRRORS AND DEFROSTER. GM HAS DESIGNED A CIRCUIT THAT HAS THE ABILITY TO TURN ITSELF ON EVEN WHEN THE CAR IS OFF AND THE KEY REMOVED! BUT EVEN WORSE GM REFUSES TO PAY FOR THE PARTS OR LABOR TO REPAIR MY TRUCK. I HAVE MADE SEVERAL CALLS TO GM CUSTOMER SERVICE AND WHILE INITIALLY ENCOURAGING GM HAS REFUSED TO STAND BEHIND THEIR PRODUCT. HOWARD THE CUSTOMER SERVICE REPRESENTATIVE AT GM COULDN'T DISCLOSE TO ME THE AMOUNT OF FINANCIAL HELP THEY OFFERED THE DEALERSHIP, IT TURNS OUT THEY DIDN'T OFFER ANY HELP AT ALL. I'M NOT SURE I WILL BUY ANOTHER GM PRODUCT AFTER THIS EXPERIENCE.

THE AUTOMATIC BELT TENSIONER PULLEY IS IN THE PROCESS OF GOING OUT. THE PULLEY ITSELF IS SLOWLY SUFFERING FROM A HIGH PITCHED WHINING NOISE WHICH IS CAUSED BY BEARING FAILURE. WITH THE CURRENT MILEAGE THE PART IN QUESTION SHOULDN'T BY ANY MEANS BE FAILING, THE TENSIONER WORKS FINE BUT THE PULLEY WOBBLES A BIT TOO MUCH. IF THE PULLEY CONTINUES TO WOBBLE MORE AND FINALLY RESULTS IN CATASTROPHIC FAILURE IT CAN SHRED THE SERPENTINE BELT WHICH WILL RENDER THE VEHICLE USELESS OR EVEN BECOME A DANGER TO ANY AND ALL OCCUPANTS IN THE VEHICLE ESPECIALLY IF IT FAILS ON THE HIGHWAY. IF THE BELT GOES OUT IT CAN BEND OTHER PULLEYS OR SHEAR OFF PULLEYS, BOLTS, OR EVEN BEND THE HARMONIC BALANCER (ENGINE VIBRATION DAMPENER) WHICH WOULD RESULT IN A BLOWN OR SEIZED UP ENGINE. I'LL ALSO ADD THAT THE BELT COULD CAUSE A FIRE IF IT GETS WEDGE BETWEEN OTHER SPINNING PULLEYS AT THE TIME OF THE PULLEY'S BEARINGS OVERHEATING AND THE PULLEY EITHER BREAKING OFF OR CAUSING THE BELT TO SHRED. *TR

CHECK ENGINE LIGHT IS DISPLAYED AND THE MOTOR IS HESITATING. THIS ISSUE IS A SECOND OCCURRENCE DUE TO THE VALVE COVER LEAKING AND CAUSING THE SPARK PLUGS TO GO BAD. FIRST TIME THE VEHICLE WAS UNDER WARRANTY AT APPROXIMATELY 29000 MILES AND NOW THE VEHICLE HAS 39000 MILES AND THE ISSUE HAS RECURRED. THIS APPEARS TO BE A CONTINUALLY RECURRING PROBLEM FOR 2011 CHEVROLET SILVERADO TRUCKS. *TR

I WAS TRAVELING ON A DIVIDED HIGHWAY AND APPROACHING A SLOW MOVING TRUCK IN THE RIGHT LANE AHEAD OF ME. THERE WAS ANOTHER TRUCK BEHIND ME IN MY LANE. I MOVED TO THE LEFT LANE TO PASS THE SLOW TRUCK. JUST AFTER I BEGAN THE PASS MY PICKUP SLOWED QUICKLY AND BEGAN FLASHING ERROR MESSAGES: STABILITY CONTROL DISABLED, ENGINE POWER REDUCED & SERVICE STABILITRAK. THE TRUCK BEHIND ME HAD MOVED UP CLOSE AND FOLLOWED ME AROUND THE SLOW MOVING TRUCK. I WAS UNABLE TO ACCELERATE AND CONTINUED SLOWING QUICKLY. I HAD JUST ENOUGH ROOM TO SWERVE IN BEHIND THE SLOW TRUCK AS MY SPEED FELL BELOW ITS SPEED. THE TRUCK BEHIND ME NARROWLY AVOIDED A REAR IMPACT WITH MY TRUCK, WHICH, I BELIEVE, WOULD HAVE BEEN CATASTROPHIC. I PULLED TO THE RIGHT AND TRIED TO SPEED UP. ABOUT 40 MPH WAS ALL MY TRUCK WOULD DO. I STOPPED AND GOT OUT THE MANUAL. IT SAID TO RESET THE STABILITRAK, TURN THE VEHICLE OFF FOR 30 SECONDS. I DID THAT AND THE TRUCK SEEMED TO FUNCTIONED NORMALLY, AT LEAST AS FAR AS ENGINE POWER. I STILL HAD TRACTION CONTROL & STABILITRAK ERROR MESSAGES AND THE SERVICE ENGINE LIGHT WAS ON. I WAS ABLE TO RETURN 40 MILES TO MY HOME TOWN WITH NO FURTHER INCIDENTS. I WAS ABLE TO GET MY TRUCK INTO THE CHEVY DEALER ON THE 30TH. THE SERVICE REP RECOGNIZED MY DESCRIPTION IMMEDIATELY AS A "THROTTLE SENSOR" FAILURE. IT WAS REPAIRED UNDER WARRANTY. THERE HAVE BEEN NO FURTHER INCIDENTS. MY CONCERNS ARE DUAL: FIRST, ONLY LUCK AND YEARS OF EMERGENCY VEHICLE OPERATION TRAINING ENABLED ME TO AVOID BEING HIT FROM BEHIND BY THE FOLLOWING TRUCK WHEN MY TRUCK UNEXPECTEDLY AND WITHOUT WARNING LOST POWER. AN IMPACT WOULD HAVE LIKELY BE LIFE THREATENING CONSIDERING THE SPEED AND PROXIMITY OF TWO TRUCKS. SECOND, SUBSEQUENTLY, I HAVE FOUND MULTIPLE INTERNET REPORTS OF THIS ISSUE GOING BACK SEVERAL MODEL YEARS AND MY SERVICE PAPER WORK INDICATES A GM SERVICE BULLETIN FOR IT EXISTS. *TR
