    I took My 2012 GMC Sierra with 112,410 miles in for annual safety inspection and was told that my frame has a hole in it and is cracked, hence un-inspectable in the state of Vermont. I then took it to a welding shop to get an estimate on repair and the tech told me he sees this all the time on this era GM/Chevy trucks. This is clearly a widespread incident and GM should be held accountable like Toyota was years ago with its bad frames.O

  • Filed Apr 2023

    Vehicle has just over 113,000 miles and the frame is already severely compromised due to rust. Nearly all factory coating is gone. I believe the sub par wax like coating that GM used from the factory was never intended to last anywhere near or over 100,000 miles. I have personally inspected numerous 2007-2013 GMT900 trucks in or around ohio and have found similar severe rust issues. All vehicles inspected were between 60,000 and 120,000 miles. The rust issues are the worst in the areas directly in front of the rear axle where the frame drops. Nearly every vehicle inspected has structure compromising rust in this area. GMT900 platform vehicles with rust issues in this area are unsafe to be on the road, yet they remain popular in multiple service industries and are frequently seen pulling trailers. GM has done a great disservice to their customers by using a sub par coating on the most important structural component in a vehicle. These trucks should easily last well over 250,000 miles but due to poor coatings they have a hard time breaking 100,000 miles.

    June 29, 2025, Driving on the St. Francis loop in Amarillo, TX, brake lights start flashing, the warning sounds happening, no brakes. I had already slowed down to 35-45 mph due to road construction ahead. I weaved through the cones and as soon as possible, hit the ditch and then coasted to a stop. (I didn’t think about the emergency brake, in my panic.) I turned the vehicle off and called my husband. I decided that I wasn’t pulled over far enough over in the ditch, so I started the pickup again. The lights and warning signals for the brakes were gone and when I pressed on the brake pedal, there were brakes again. I drove home at 35 mph, knowing I could use the emergency brake at that speed, if needed, and had brakes all the way home. GMC Bender repaired truck. After driving approximately 3 miles since repaired, our daughter took the truck to Grease Monkey. She was at the garage door; employee said the pickup didn't need an oil change. She backed out and didn’t have brakes (no warning lights or sounds) and as the truck continued backing, it hit the Grease Monkey sign at the east end of their lot and broke it, knocked the sign over. An employee walked over to see what happened, she told him that she didn’t have brakes. He sat in the pickup seat and pushed on the brakes and said, yes, you don’t have brakes! The police were called, and the officer who showed up took pictures, gave us his card, talked with my husband and talked to the Grease Monkey boss. August 6, 2025, I called GMC Bender Service Department (11 mins. 8 secs.) I told them what had happened. They sent a tow truck to bring the pickup back to their shop. September 16, 2025, my husband texted me saying GMC Bender said that the pickup shows another EBS Modulator Fault. No new parts… used one would be $1293 installed. A week to get it here, no guarantees. There's more details, but the vehicle cannot be repaired to guarantee brakes will work properly. Please help us know what to do next.

    Lifter Failure: I was traveling to a State Park in Northern Michigan when my engine starting running very rough with major power loss. My check engine light activated, and I pulled over as soon as I could. It was dangerous because I was pulling a camper and I had to drive well under the speed limit. The Certified Chevy Dealership discovered a collapsed lifter and Cam damage. They considered this as catastrophic engine failure, and I was completely shocked as the vehicle had roughly 129k miles on it. There was no indication of failure prior to this incident as the vehicle ran perfect. I am very disappointed in GM as I have a co-worker with the same year truck that had the exact same issue shortly after I did. A friend of mine also had this happen with a 2014 vehicle of same make and model. It appears that this is a common issue with GM's newer 5.3 engines which used to be extremely reliable (99-07). GM needs to fix these lifter issues because a newer technology engine should last much longer.

ME AND THE BOYS WENT IN K-MART FOR A FEW MINUTES. UPON RETURNING AND GETTING BACK ON THE ROAD, I NOTICED MY CAR WAS PULLING BAD RIGHT AND THE STEERING WHEEL WAS SHAKING VERY BADLY. I MANAGED TO DRIVE IT THE ADDITIONAL 30 MILES BACK HOME. WHEN I STARTED THE TRUCK THE NEXT MORNING, THE STEERING WHEEL SHAKE WAS TOO BAD TO CONTINUE ANYWHERE BUT THE DEALERSHIP. I DROVE TO THE DEALERSHIP AND THEY SAID THAT THE TIRES WOULD BE COVERED UNDER MY EXISTING "BUMPER TO BUMPER" WARRANTY AS THE DEALERSHIP NOTICED THAT THERE WAS A HUGE BULGE IN THE TIRE WHICH WAS CAUSING ALL OF THE COMMOTION. UPON FURTHER INSPECTION, IT WAS NOTED THAT THE FRONT RIGHT TIRE ALSO HAD BULGES, THESE IN THE SIDEWALL WHERE THE TIRE MEETS THE RIM. THE DOT BATCH NUMBER IS #PJ6KA5IV 32/11 AND BOTH TIRES WERE FROM THE SAME BATCH. I WAS DRIVING AROUND WITH TWO DEFECTIVE TIRES!!!!!!! WITH MY 8 YEAR SON, 4 YEAR OLD SON, 3 WEEK OLD DAUGHTER AND MY WIFE. THIS IS UNACCEPTABLE! OUR LIVES WERE AT RISK! IMAGINE MY SURPRISE WHEN THE DEALERSHIP CALLED THE FOLLOWING MORNING AND SAID THAT GM HAD "CHANGED THEIR POLICIES AND THEY WOULD ONLY BE GIVING ME A 30% DISCOUNT." I UNDERSTAND POLICY BUT THESE TIRES ONLY MEASURED LITTLE WEAR AND SHOULD HAVE AT LEAST 55% MORE TREAD LIFE BASED ON THE EXACT TIRE MEASUREMENTS. INSTEAD, GM IS USING A SLIDING SCALE FOR MILEAGE THAT DOES NOT TAKE ACTUAL MEASUREMENTS INTO THEIR ASSESSMENT. SO NOW, I AM OUT $350 FOR 2 NEW TIRES THAT SHOULD HAVE LASTED A WHOLE LOT LONGER AND NO HELP FROM GOODYEAR OR GMC. *TR

    They should be responsible for repairs or replacement of the cheap made frames that rust away so fast so u ain’t gotta worry about your truck fallling apart going down the rd and the lower control arms made of cast that rust from inside out and you don’t know until breaks while driving along with camber adjustments where they can throw alignment out with a single bump. Mostly the frame replacement is major always having to plate frame or check to make sure it will be able travel long trips or haul stuff in bed or a trailer with breaking or falling off truck causing wreck frame repair is major and time consuming if you don’t have proper stuff and definitely expensive and lower control arms that’ll make a wheel come real fast and it’s time consuming and expensive too but very dangerous and breaks and causes damage right then and there at high or low speed on highways or interstates

    The contact owns a 2012 GMC Sierra 1500. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted, especially between second and third gears. The check engine warning light was intermittently illuminated. In addition, the contact stated that the engine felt as though the engine mounts were inoperable. The contact pulled over to the side of the road and turned off the vehicle. The vehicle was restarted, and the vehicle resumed normal driving. The vehicle was taken to the dealer; however, no cause for the failure was found. The vehicle was not repaired. The contact stated that the failure persisted. The manufacturer was made aware of the failure, but no assistance was offered. The failure mileage was approximately 20,000.

I WANTED A SECOND OPINION BECAUSE I HAVE NEVER HEARD OF A FLYWHEEL GOING BAD IN MY LIFE. AFTER SPEAKING WITH A FEW MECHANICS WE ALL AGREED THAT IT WAS NOT THE FLYWHEEL. ON 4APR I TOOK MY VEHICLE TO ANOTHER DEALER WHO CONFIRMED THAT THE TICKING WAS THE FLYWHEEL. THE FLYWHEEL HAD TO HAVE BEEN DEFECTIVE AT TIME OF MANUFACTURING. IT JUST CRACKED FOR NO GOOD REASON OTHER THAN IT WAS POORLY MADE. 2012 GMC SIERRA 1500 FLYWHEEL JUST CRACKED OUT OF NOWHERE ENDANGERING THE LIVES OF AN ENTIRE FAMILY AND WHO KNOWS WHO ELSE IF IT HAD SHATTERED.THE VEHICLE WAS TICKING AFTER A MORNING START WHILE SITTING IDLE.

    I went to get the vehicle inspected today and was told it failed due to the chassis frame in the rear being rusted thru. This could cause the suspension to collapse any time. I see on the internet that multiple others have and are experiencing the same with the Sierra and Silverado. My vehicle has unlimited washes and has been washed 40 times a year and looks new from the outside.

    I WAS DRIVING MY TRUCK UP A 6% PERCENT GRADE WHEN THE CHANGE FUEL FILTER SOON WARNING POPPED UP, ABOUT A MINUTE LATER THE VEHICLE STARTED TO LOSE POWER, I KEPT DRIVING TO TRY AND GET OVER THE HILL SO I COULD MAKE IT TO A REPAIR SHOP TO HAVE IT CHECKED OUT. I WAS ONLY ABLE TO MAKE IT ABOUT 2 MILES AFTER THE WARNING SHOWED UP BEFORE THE VEHICLE COMPLETELY SHUT DOWN AND WOULD NOT RESTART. (THERE WAS NOT ENOUGH ROOM ON THE SHOULDER TO PULL OVER ON MY SIDE THE ROAD SO I TRIED TO TURN ACROSS THE HIGHWAY WHERE THERE WAS AN EMERGENCY PULL OUT AND AS I DID THE TRUCK DIED SIDEWAYS RIGHT IN THE MIDDLE OF THE HIGHWAY, TAKING UP SEVERAL LANES OF TRAFFIC, FORTUNATELY THERE WAS ENOUGH INCLINE THAT I WAS ABLE TO ROLL BACKWARDS AND PULL OVER UP AGAINST THE GUARDRAIL) OF COURSE I HAD NO POWER STEERING OR POWER BRAKES SINCE THE TRUCK WAS NOT RUNNING. IT WAS A VERY DANGEROUS SITUATION! I WAS ABLE TO GET MY TRUCK TOWED TO THE LOCAL GM REPAIR SHOP WHERE THEY DETERMINED THAT THE FUEL PUMP HAD A CATASTROPHIC FAILURE AND HAD SENT ALUMINUM SHAVINGS THROUGHOUT THE ENTIRE FUEL SYSTEM. THEY SAID THE REPAIRS WOULD BE APPROXIMATELY $10,000 SO I CONTACTED GM AND DESCRIBED WHAT HAPPENED, AND THEY BASICALLY TOLD ME TO GO FLY A KITE. AFTER DOING SOME RESEARCH ONLINE IT LOOKS LIKE THERE HAS BEEN A MAJOR PROBLEM WITH GM TRUCKS WITH THE DURAMAX MOTOR FROM 2011-2016 AFTER THEY CHANGED THERE FUEL PUMP FROM THE CP3 HIGH VOLUME LOW PRESSURE PUMP TO THE CP4 HIGH PRESSURE LOW VOLUME PUMP. WHICH MEANS THE PUMP RUNS WITH LESS LUBRICATION WHICH RESULTS IN PUMP FAILURE, AND NOT JUST FAILURE BUT CATASTROPHIC FAILURE WHICH CAUSES MAJOR DAMAGE TO THE ENTIRE FUEL SYSTEM. I HAVE BEEN A LOYAL GM OWNER FOR OVER TWENTY YEARS, AND I AM EXTREMELY DISAPPOINTED THAT GM IS NOT WILLING TO MAKE IT RIGHT.

MY MECHANIC STATED HE HAS REPAIRED SEVERAL OF THESE ISSUES ON OTHER GMC'S. THE PROBLEM IS THE TOP OF THE FUEL TANK IS RUSTED WHERE THE FUEL PUMP IS LOCATED AND GAS SPRAYS UPWARDS ONTO THE BOTTOM SIDE OF THE BED AND IS VERY COSTLY AND DIFFICULT TO REPAIR. I'M SURE GM IS AWARE OF THE PROBLEM, HOWEVER, THEY HAVE CHOSEN TO IGNORE THE ISSUE. THIS IS MOST DEFINITELY A SAFETY ISSUE!

    APPARENTLY GM USES PEANUT OIL TO LUBRICATE WIRING SO THEY CAN MORE EASILY INSULATE, ETC (ACCORGING TO THE GM DEALER).

    June 29, 2025, Driving on the St. Francis loop in Amarillo, TX, brake lights start flashing, the warning sounds happening, no brakes. I had already slowed down to 35-45 mph due to road construction ahead. I weaved through the cones and as soon as possible, hit the ditch and then coasted to a stop. (I didn’t think about the emergency brake, in my panic.) I turned the vehicle off and called my husband. I decided that I wasn’t pulled over far enough over in the ditch, so I started the pickup again. The lights and warning signals for the brakes were gone and when I pressed on the brake pedal, there were brakes again. I drove home at 35 mph, knowing I could use the emergency brake at that speed, if needed, and had brakes all the way home. GMC Bender repaired truck. After driving approximately 3 miles since repaired, our daughter took the truck to Grease Monkey. She was at the garage door; employee said the pickup didn't need an oil change. She backed out and didn’t have brakes (no warning lights or sounds) and as the truck continued backing, it hit the Grease Monkey sign at the east end of their lot and broke it, knocked the sign over. An employee walked over to see what happened, she told him that she didn’t have brakes. He sat in the pickup seat and pushed on the brakes and said, yes, you don’t have brakes! The police were called, and the officer who showed up took pictures, gave us his card, talked with my husband and talked to the Grease Monkey boss. August 6, 2025, I called GMC Bender Service Department (11 mins. 8 secs.) I told them what had happened. They sent a tow truck to bring the pickup back to their shop. September 16, 2025, my husband texted me saying GMC Bender said that the pickup shows another EBS Modulator Fault. No new parts… used one would be $1293 installed. A week to get it here, no guarantees. There's more details, but the vehicle cannot be repaired to guarantee brakes will work properly. Please help us know what to do next.

    I HAVE GOODYEAR WRANGLER SR-A 265 60R20 TIRES ON MY SIERRA DENALI HD 2500. I WAS ON THE WAY BACK FROM NC VIA I-95 AND PULLED OVER SO MY WIFE COULD NURSE OUR 3 WEEK OLD. ME AND THE BOYS WENT IN K-MART FOR A FEW MINUTES. UPON RETURNING AND GETTING BACK ON THE ROAD, I NOTICED MY CAR WAS PULLING BAD RIGHT AND THE STEERING WHEEL WAS SHAKING VERY BADLY. I MANAGED TO DRIVE IT THE ADDITIONAL 30 MILES BACK HOME. WHEN I STARTED THE TRUCK THE NEXT MORNING, THE STEERING WHEEL SHAKE WAS TOO BAD TO CONTINUE ANYWHERE BUT THE DEALERSHIP. I DROVE TO THE DEALERSHIP AND THEY SAID THAT THE TIRES WOULD BE COVERED UNDER MY EXISTING "BUMPER TO BUMPER" WARRANTY AS THE DEALERSHIP NOTICED THAT THERE WAS A HUGE BULGE IN THE TIRE WHICH WAS CAUSING ALL OF THE COMMOTION. UPON FURTHER INSPECTION, IT WAS NOTED THAT THE FRONT RIGHT TIRE ALSO HAD BULGES, THESE IN THE SIDEWALL WHERE THE TIRE MEETS THE RIM. THE DOT BATCH NUMBER IS #PJ6KA5IV 32/11 AND BOTH TIRES WERE FROM THE SAME BATCH. I WAS DRIVING AROUND WITH TWO DEFECTIVE TIRES!!!!!!! WITH MY 8 YEAR SON, 4 YEAR OLD SON, 3 WEEK OLD DAUGHTER AND MY WIFE. THIS IS UNACCEPTABLE! OUR LIVES WERE AT RISK! IMAGINE MY SURPRISE WHEN THE DEALERSHIP CALLED THE FOLLOWING MORNING AND SAID THAT GM HAD "CHANGED THEIR POLICIES AND THEY WOULD ONLY BE GIVING ME A 30% DISCOUNT." I UNDERSTAND POLICY BUT THESE TIRES ONLY MEASURED LITTLE WEAR AND SHOULD HAVE AT LEAST 55% MORE TREAD LIFE BASED ON THE EXACT TIRE MEASUREMENTS. INSTEAD, GM IS USING A SLIDING SCALE FOR MILEAGE THAT DOES NOT TAKE ACTUAL MEASUREMENTS INTO THEIR ASSESSMENT. SO NOW, I AM OUT $350 FOR 2 NEW TIRES THAT SHOULD HAVE LASTED A WHOLE LOT LONGER AND NO HELP FROM GOODYEAR OR GMC. *TR
