2011 Chevrolet Silverado 1500 Engine Problems

Your truck has stalled out and left you stranded multiple times in just a few weeks of ownership, including dangerous situations in heavy traffic with your children in the vehicle. The dealership replaced the fuel pump, but the fuel light came on immediately after pickup, and the truck stalled again about a week later. The underlying fuel system issue may not have been fully resolved by the fuel pump replacement alone.

Your engine is making an abnormal knocking sound while parked. A mechanic diagnosed this as damage to the engine lifters and engine itself, both of which need to be replaced. This occurred at 173,000 miles. Repair will involve replacing the damaged lifters and potentially significant engine work or replacement.

The contact owns a 2011 Chevrolet Silverado. The contact stated that while driving at an undisclosed speed, she heard a loud abnormal tapping sound at the hood of the vehicle. The contact then stated that upon inspection, she noticed that the tapping sound was coming from the lifter and lifter arm when the piston dropped down. The traction control warning light was illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the pistons, rocker arm, head valve seals, and lifter arm needed to be replaced. The vehicle was repaired however, the failure recurred. The contact then stated that upon research she was informed that the engine may need to be replaced. The vehicle was not repaired. The dealer was not notified of the failure. The manufacturer was not notified of the failure. The failure mileage was approximately 260,000.

Hybrid system failed while driving resulting vehicle becoming disabled on the road. Took to GM shop, they informed that the Hybrid System failed. Parts are unavailable because GM discontinued them. GM shop is not willing to replace with used battery due to the lack of reliability “we would have the same problem just a few miles down the road”. GM shop bipassed hybrid system resulting in the vehicle only working if it is on a trickle battery charger. Filed complaint with GM and GM told us they cannot help because the part is discontinued. This vehicle cannot operate without being on a trickle charge which is a hazard to all people on the road. GM discontinued a part that is vital to the vehicle’s safety and usability. GM provided no resolution, therefore putting all 2011 Chevy Silverado Hybrid vehicles at risk for immediate and unforeseen vehicle failure.

While driving, all the sudden my check engine light came on (flashing), and my stabilitrack light came on. The engine started running really rough, and lost power. It is like major misfire. Upon reading up on this, it is a problem with this type engine. I saw about 2000 people with the same issue. Nothing works to resolve this problem. Coils, plugs, and wires were replaced, and still the same.

Vehicle door locks activate lock and unlock while simultaneously downshifting the transmission, the engine dies, the dash cluster stops working, engine starts again, dash cluster begins working again. After this occurs, when the vehicle is shut off, there is a loud "pop" sound heard over the speakers and no interior lights. The vehicle may or may not have any cab power. Cycling the ignition provides little to no help. After the vehicle sits for a while, it may or may not start again. The vehicle stereo will randomly change from FM to aux. The a/c panel will flicker and the blower motor will fluctuate. This can also be seen while watching the battery gage on the instrument cluster. It will go from around 14 volts DC to around 9 volts DC and back up again.

OIL ENGINE CONSUMPTION ABOUT EVERY 1200 MILES

IN JUNE OF 2019 MY VEHICLE WAS BROUGHT INTO BEGNAL MOTORS IN KINGSTON NY WITH THE CHECK ENGINE LIGHT ON. THERE WAS ALSO A WARNING FOR THE STABILTRAX SYSTEM AND LOW OIL PRESSURE. I BROUGHT IT TO BEGNAL MOTORS BECAUSE THAT IS WHERE I PURCHASED THE VEHICLE. THE VEHICLE WAS STILL UNDER WARRANTY AT THIS POINT. THEY BEING A DODGE DEALER THEN SENT THE TRUCK OVER TO ROMEO CHEVY WHO DIAGNOSED IT AS AN ENGINE MISFIRE. THEY HAD THE TRUCK FOR TWO MONTHS FOR THE REPAIR WHICH THE WARRANTY COVERED.

I WOULD APPRECIATE SOME HELP IN THIS MATTER THE VEHICLE HAS ONLY 105000 MILES AND I AM BEING TOLD IT NEEDS A NEW ENGINE BECAUSE OF OIL PRESSURE. *TR

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 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?

TL* THE CONTACT OWNS A 2011 CHEVROLET SILVERADO 1500. WHILE DRIVING 55 MPH, THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE DEALER DIAGNOSED THAT THE OIL PRESSURE SENSOR NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 118,000.

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

AT 36000 MILES THE ENGINE BURNS OIL. SO FAR AS OF 46000 MILES PISTONS BURNED HAVE BEEN REPLACED PVC FILTER AND VALVE WERE REPLACED ALONG WITH VALVE COVER. AT PRESENT 54000 MILES ENGINE STILL BURNS OIL. *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

THIS IS A DEALER DEMO VEHICLE, FIRST 2235 MILES WERE DEMO. DURING MY FIRST MORNING (12HOURS AFTER PICKING UP AT DEALER) OF OWNERSHIP I WAS DESCENDING DOWN A HILL WITH THE CRUISE ON, AND THE VEHICLE PROCEEDED TO OVER SPEED APPROXIMATELY 5-7MPH. I TRAVEL THIS HILL BOTH WAYS TO/FROM WORK DAILY AND THIS HAPPENS EVERYTIME. I THOUGH THIS MIGHT BE AN ABNORMAL ADJUSTMENT WITHIN THE COMPUTER/ETC SO WHILE TAKING IN TO THE DEALER FOR A TPMS (TIRE PRESSURE MONITOR SYSTEM) ISSUE I MENTIONED THE OVERSPEED ISSUE TO THE SERVICE WRITE UP AND THEY SAID THAT IT WAS NORMAL. I DON'T AGREE, BUT MAYBE IT IS. IT DOES ADJUST BACK TO NORMAL CRUISE SET SPEED BUT IS UNIQUE. I HAD A 2002 DODGE RAM 1500 PREVIOUSLY AND IT DID NOT DO THIS, AND I HAVE DROVE OTR (OVER THE ROAD) SEMI-TRUCKS AND KNOW THE DIFFERENCE WITH OVERSPEED BEING NORMAL AND ABNORMAL. I WOULD LIKE THIS TO BE LOOKED INTO, AS IT COULD BE A HAZARD THAT COULD LEAD TO UNSAFE SITUATION. *TR
