2010 CHEVROLET SILVERADO 1500 Power Train Problems

GM 3.0 diesel engine has a coolant control valve that fails putting the vehicle into a reduced power mode causing the vehicle to have significantly reduced acceleration and putting the engine fan at full to reduce engine heat. When stopped, the engine had been running very hot as you can hear the popping from the metal as it cools off. The part to repair this issue is 40009158 and is being replaced by 40009452. This part is on a nationwide backorder with hundreds on the waiting list just at this time for a repair and no clear picture of when parts will become available. Many other cases have been reported since 2021 for the same issue with the 3.0 GM Duramax engine with engine code/styles LM2 & LZO.

Nothing

General Motors USA produced several years of vehicles with a faulty transmission control module (TCM). From 2008-25 Chevrolet and GMC trucks with the 6.6L Duramax engine and Allison 1000 transmission all used the same TCM; part 24256861. This part has experienced a very high failure rate. GM has put out Service Bulletins acknowledging this issue and has not made a recall. Safety concerns with the TCM are related to overheating. I have a 2010 Chev Duramax 2500 with that TCM; on July 16, 2022 my truck was taken in for repairs due to the failure of the TCM. For 14 months the truck has been down due to no new parts available from GM and no parts being manufactured in 2022. This has been a substantial impact to me as a consumer. There is a need for new improved parts for this long-standing faulty TCM issue. The lack of recall on this TCM is subjecting consumers to risks of overheating the transmission system as well as incalculable down-time impacts related to personal and business owned trucks. This problem of the faulty TCM on my truck was confirmed by the local auto repair shop I use as well as the local Chevrolet dealership in Delta, CO. The TCM, will long known problems acknowledged by GM, needs to be on a recall for consumer protection.

I got a code p2138 Throttle/Pedal Position Sensor/Switch. Upon doing my own research on this code I found out it is a manufacture defect. And they are aware this is caused because the manufacturer did not seal the antenna correctly so water gets in and damages wires and sensors

Engine oil pressure was critically low. I could not drive the vehicle until I had it repaired.

THE VEHICLE IS HAVING ELECTRICAL ISSUES AND IT EFFECTS IT BY SHUTTING OFF IN THE MIDDLE OF TRAFFIC ON A HIGHWAY IT ALSO EFFECTS THE THROTTLE SENSOR BY ACCELERATING WHEN YOU COME TO A STOP AT A STOP LIGHT AND THE TRANSMISSION JUMPS A GEAR WHEN IT DOES THAT.

TRUCK PURCHASED BY MY FATHER IN 2010 FROM CHEVROLET DEALERSHIP. I PURCHASED THE TRUCK FROM HIM IN 2016. THE TRUCK HAS UNDER 120,000 MILES AND DUE TO FAULTY ENGINE AND SENSORS THE VEHICLE HAS SEIZED LEAVING ME WITH THOUSANDS IN REPAIR AND NO VEHICLE. THR VEHICLE BROKE DOWN ON ME WITH MY CHILDREN SEVERAL TIMES LOSING PWOER, SHAKING UNCONTROLLABLY. THERE WAS OIL AND THE PRESSURE UNIT DID NOT READ LOW OR SHUT THE TRUCK DOWN.. MY TRUCK ALSO HAS AN AIRBAG RECALL FROM 2016 THAT THERE IS NO REMEDY FOR. I STILL MAKE PAYMENTS ON THIS VEHICLE AND IT IS EXTREMELY UNSAFE COSTING THOUSANDS FOR REPAIR. GM SHOULD BE RESPONSIBLE FOR FAULTY VEHICLES.

TL* THE CONTACT OWNS A 2010 CHEVROLET SILVERADO 1500. WHILE DRIVING APPROXIMATELY 55 MPH, THE VEHICLE BEGAN TO HESITATE. THE CONTACT PULLED THE VEHICLE OVER TO THE SIDE OF THE ROAD AND DROVE HOME. THE VEHICLE WAS TAKEN TO LIBERTY CHEVROLET (105 COOLEY WAY, VILLA RICA, GA 30180) WHERE IT WAS DETERMINED THAT THE TRANSMISSION FAILED AND NEEDED REPLACEMENT. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 140,000.

WHILE DRIVING ON HIGHWAY AT 65-70 MPH, ELECTRICAL SYSTEM SHUT DOWN THE TACHOMETER, SPEEDOMETER, FUEL AND ALL OTHER GAUGES. LIGHTS AND TURN SIGNALS REMAINED ON. TRANSMISSION DOWNSHIFTED AND WOULD NOT SHIFT UP AFTER A COMPLETE STOP. SHIFTING TRANSMISSION TO PARK, REVERSE OR NEUTRAL WOULD NOT REGISTER, BUT WOULD SHIFT. SERVICE ENGINE, ABS LIGHT AND STABILITRAK OFF LIGHT CAME ON. ON A SEPARATE OCCASION MESSAGE CENTER READ SERVICE TRACTION CONTROL, SERVICE STABILITRAK ON A SIMILAR OCCURRENCE, WHILE COMING TO A STOP. THIS HAS OCCURRED SEVERAL TIMES. DROVE HOME, WITHOUT SPEEDOMETER AND MILES DID NOT REGISTER ON ODOMETER.

THREE DIFFERENT TIMES THE TRUCK THROTLE STUCK TO THE FLOOR ONLY WAY TO CORRECT IT WAS TO TURN THE KEY OFF THEN THE GAS PETAL WOULD RELEASE. WOULD HAFT TO PULL OFF ROAD THEN RESTART THE TRUCK. THE TRUCK WAS ON HWY,EATHER PASSING OR PULLING ON THE INTERSTATE.

MY HUSBAND AND I WERE DRIVING ABOUT 45 MPH DOWN A STEEP HILL, TOWING A UTILITY TRAILER, ON SR87 IN THE MOUNTAINS WHEN THE DOOR LOCKS CLICKED AND THE ENGINE TURNED COMPLETELY OFF WITH NO WARNING. THE STEERING WHEEL LOCKED UP AND THE BRAKES DID NOT WORK. MY HUSBAND PUT THE CAR IN NEUTRAL AS IT ACCELERATED DOWN A CLIFF AND ATTEMPTED TO RESTART IT WITH NO LUCK. THERE WERE NO CARS IMMEDIATELY AROUND US SO WE WERE ABLE TO COAST TO A STOP ON A STEEP INCLINE. WHEN WE GOT OUT TO CHECK IT, THERE WAS OIL ALL OVER THE WHEEL WELLS AND STILL NO WARNING LIGHTS HAD COME ON. WE TOOK IT TO THE DEALERSHIP AND THEY TOLD US THE TRANSMISSION WAS COMPLETELY BLOWN ON OUR 6 YEAR OLD TRUCK. THERE WAS ZERO EXPLANATION AS TO WHY THIS WOULD HAPPEN AS WELL AS TO WHY WE HAD NO WARNING PRIOR TO THE ENGINE SHUTTING OFF. WE WERE TOLD TO PAY BETTER ATTENTION TO THE TEMP. EVEN THOUGH IT DID NOT OVERHEAT. CHEVY OFFERED NO RELIEF OR HELP. WE WERE QUOTED A PRICE ABOUT $2000 LESS FOR THE INITIAL TRANSMISSION REPAIR THAN IT WOULD HAVE COST SO WE TOOK IT TO A NON-DEALERSHIP SHOP TO REPAIR. THIS WEEKEND, THE CHECK ENGINE LIGHT CAME ON OUT OF NOWHERE INDICATING LOSS OF POWER AND THE STABILITRACK WARNING CAME ON EVEN THOUGHT THAT WAS PREVIOUSLY REPAIRED BY A DEALERSHIP ON A TSB ABOUT A YEAR PRIOR TO THE TRANSMISSION GOING OUT. THE CODE IT THREW THIS TIME WAS P0305 AND WE WERE ON VERY LIMITED POWER DRIVING BACK HOME FROM A ROAD TRIP. COULD NOT GO MORE THAN 40 MPH UPHILL. EXTREMELY CONCERNED FOR OUR SAFETY SINCE THE VEHICLE CAN TURN OFF WITH NO WARNING. ALSO, THE MONEY SPENT IS RIDICULOUS.

DEFECTIVE TRANSMISSION COOLER LINES LEAK AT EVERY FLEX HOSE CONNECTION. TRANS FLUID SPRAYS ON ROAD AND ON THE WINDSHIELDS OF VEHICLES FOLLOWING. THIS ON MANY YEARS OF THESE, MY 2005 SILVERADO 2500 HAD THE SAME DEFECT.

TRANSMISSION MAKES CLUNKING NOISES WHEN SHIFTING AT 25,33 &46 MPH. SOMETIMES THERE IS A VERY LOUD CLUNK FROM THE TRANSMISSION. THIS HAS BEEN OCCURRING EVER SINCE WE HAD 24000 MILES ON THE VEHICLE. CURRENT MILES 59000MI. GM DEALERSHIPS COULD NOT VERIFY THE NOISES. ONE DEALER CHANGED THE TCM AND TORQUE CONVERTER. VERY SAME NOISES WITHIN THE SAME WEEK OF THE CHANGE. STILL HAPPENING.

HEARD A TICKING NOISE COMING FROM UNDER HOOD OF VEHICLE WHILE PULLING AWAY FROM FAST FOOD ESTABLISHMENT. PULLED OVER TO FIND THAT TRANSMISSION DIPSTICK TUBE HAD FRACTURED. WENT HOME AND FOUND THAT GM HAD ISSUED A "CUSTOMER CARE BULLETIN" BACK IN 2012 ABOUT THIS ISSUE. HOWEVER, I RECEIVED NO LETTER ABOUT THIS PROBLEM. I CONTACTED GM THIS MORNING AND THEY REFUSE TO FIX THE PROBLEM UNDER THIS "BULLITEN". THIS SHOULD NOT BE A "BULLETIN", BUT SHOULD BE A RECALL SINCE IT INVOLVES POTENTIAL PROBLEMS WITH THE TRANSMISSION. A DIPSTICK TUBE FRACTURE CAN LEAD TO WATER, DIRT, AND OTHER CONTAMINANTS GETTING INTO THE TRANSMISSION CAUSING FAILURE THAT COULD RESULT IN ACCIDENTS CAUSING SERIOUS INJURIES OR DEATH.

I PURCHASED THIS VEHICLE AT A SOMEWHAT RELIABLE LOCAL DEALERSHIP ONLY TO HAVE THE VEHICLE IN AND OUT OF THE SHOP A TOTAL OF 6 MONTHS FOR THE FIRST YEAR AND A HALF OF MY OWNERSHIP. THE PROBLEM WITH THE VEHICLE HAS BEEN, AND STILL IS, THE TRANSMISSION AND IT'S ABILITY TO SLIP IN AND OUT OF GEAR AT RANDOM. AT INTERSECTIONS, STOPS AND STARTS, AS WELL AS IN MOVEMENT THE TRANSMISSION WILL DISENGAGE AND SLAM INTO GEAR WITH A LOUD CLUNKING NOISE AND JERKING ACTION. ON AN INCLINE, IT WILL ACTUALLY ROLL BACKWARDS THUS FORCING THE NEED TO CONSTANTLY COVER THE BRAKE FOR THIS CONCERN. THE SERVICE MANAGER AT THE DEALERSHIP SAYS HE HAS DONE ALL HE CAN DO AND GM INSIST THAT THIS IS NORMAL FOR THE TRANSMISSION TO WORK THIS WAY. THEY EVEN ISSUED A COPY OF A MEMO TO THE DEALERSHIP ABOUT THIS. THEY HAVE ASSURED ME THAT IF ANYTHING WERE TO HAPPEN WITH THE TRANSMISSION IT WOULD BE COVERED. FORGET ABOUT CREATING AN ACCIDENT, OR MY WIFE OR MYSELF GETTING KILLED! I FIGURE THIS A VERY UNSAFE VEHICLE AND WILL PROBABLY HAVE TO GET RID OF IT BEFORE IT GETS RID OF ME OR SOMEBODY ELSE UNLESS GM FIXES IT AND MAKES IT RIGHT. ECONOMICALLY I'M NOT IN A GOOD POSITION TO JUST GET RID OF IT BECAUSE I OWE SO MUCH ON IT BUT EVEN IF I DID AN UNSAFE VEHICLE IS PUT BACK INTO CIRCULATION FOR SOMEBODY ELSE TO DEAL WITH. ON ANOTHER NOTE, THE SERVICE MANAGER'S SHARED WITH THAT HIS FATHER BOUGHT A 2013 CHEVROLET TRUCK WITH THE SAME PROBLEM AND HAD THE TRANSMISSION SLAM INTO GEAR THE SAME WAY MINE DID WHILE HE WAS PULLING AWAY FROM A TOLL BOOTH WHILE TOWING A BOAT BACK FROM CONNECTICUT. CONSEQUENTLY, THIS APPEARS TO BE A PROBLEM SPANNING ADDITIONAL YEARS AS WELL. CLEARLY A DEFECTIVE DESIGN IN DRIVE TRAIN. PLEASE CONSIDER INVESTIGATING THIS ISSUE AND MAKE GM RESPONSIBLE FOR ADDRESSING THIS ISSUE OTHER THAN ISSUING A MEMO AND TURNING THEIR HEADS THE OTHER WAY. THERE MIGHT BE MANY LIVES SAVE BY TAKING ACTION NOW. *TR

THIS HAS HAPPENED TWICE IN THE LAST WEEK. TODAY I WAS SITTING AT A STOPLIGHT WITH MY FOOT ON THE BRAKE AND SUDDENLY WITHOUT WARNING MY 2010 SILVERADO ACCELERATED AND LUNGED FORWARD ABOUT 3 FEET. FORTUNATELY THERE WAS NOT A CAR OR PERSON IN FRONT OF ME OR I SURELY WOULD HAVE HAD AN ACCIDENT THEN THE ENGINE STARTED MISSING. AT THE SAME TIME MY CHECK ENGINE LIGHT CAME ON. SERVICE TRACTION CONTROL, SERVICE STABILTRAK, ENGINE POWER REDUCED FLASHED ON MY DASH. I LIMPED HOME AT 10-15 MPH MAX! AFTER ABOUT AN HOUR I STARTED IT AND IT RAN JUST FINE "BOTH TIMES". THE FIRST TIME THIS HAPPENED I WAS IN A PARKING LOT WITH THE TRANSMISSION IN PARK. IT IS NOW AT MY LOCAL CHEVROLET DEALER FOR REPAIR. *TR

THE VEHICLE ACCELERATES ON ITS OWN, SOMETIMES FROM A DEAD STOP, SOMETIMES WHILE GOING AT A SET SPEED IT WILL ACCELERATE WITHOUT PRESSING THE ACCELERATOR. YOU HAVE TO FORCEFULLY PUT PRESSURE ON THE BRAKE TO SLOW DOWN. THIS HAPPENS AT VARIOUS TIMES AND AT VARIOUS SPEEDS.WE HAVE WRITTEN IT DOWN ON EVERY OCCASION AND THERE ARE 16 SO FAR. THIS VEHICLE HAS BEEN TO THE DEALER SEVERAL TIMES AND THEY HAVE YET TO REPAIR ANY OF THE PROBLEMS. THE MANUFACTURER HAS NEVER CONTACTED US DESPITE THE PROBLEMS AND COMPLAINTS. *TR

TRANSMISSION COOLING LINES ARE LEAKING WHERE RUBBER HOSE IS CRIMPED ONTO METAL HOSE, GM PART #25999419. DEALER IS AWARE OF ISSUE, AND STATES IT IS VERY COMMON, BUT WOULD NOT REPLACE UNDER WARRANTY. VEHICLE IS LESS THAN 3 YEARS OLD BUT HAS 47,XXX MILES ON IT AND THE WARRANTY IS ONLY 3 YEARS / 36,000 MILES. IF THE LINE BUSTS, IT COULD CAUSE THE TRANSMISSION TO STOP SHIFTING AND WOULD BE UNSAFE AS AUTOMATIC TRANSMISSION FLUID WOULD LEAK EVERYWHERE. *TR

TL* THE CONTACT OWNS A 2010 CHEVROLET SILVERADO 1500 PICKUP. THE CONTACT STATED THAT WHEN DRIVING AT VARIOUS SPEEDS, THE TRANSMISSION WOULD EXHIBIT AN UNUSUAL CLUNKING NOISE WHEN SHIFTING GEARS. THE VEHICLE WAS INSPECTED BY A DEALER AND INFORMED THE CONTACT THAT THE FAILURE WAS NORMAL WEAR AND TEAR. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 800.

SAFETY ISSUE WITH 2010 GMC/CHEVROLET 1500 PICKUPS WITH 6 SPEED AUTOMATIC TRANSMISSION. THE ISSUE INVOLVES DRIVING ONE OF THESE VEHICLES WITH THE TOW/HAUL MODE TURNED ON. IF GOING DOWN A HILL AT 55 TO 65 MILES PER HOUR, ACTUALLY ANY SPEED, BY LAYING YOUR FOOT ON THE BRAKE PEDAL HARD JUST HARD ENOUGH TO TURN ON BRAKE LIGHTS THESE VEHICLES WILL BEGIN DOWNSHIFTING. THE ONE I OWN WILL GO FROM 5TH GEAR TO 2ND GEAR IN LESS THAN 10 SECONDS. AT THIS POINT THE TACHOMETER WILL PEG TO THE MAX AND THE REAR TIRES WILL BEGIN TO SLIDE. I HAVE HAD THIS AT THE DEALER TWICE AND HAVE BEEN TOLD THIS IS NORMAL AND THEY RECOMMEND I DON'T USE THE TOW/HAUL MODE. MY VEHICLE HIT A SMALL BUMP IN THE ROAD ONCE WHILE THIS WAS HAPPENING AND ACTUALLY WAS COMPLETELY SIDEWAYS AT 50 MPH. *TR
