2011 GMC Sierra 1500

Vehicle experienced a catastrophic mechanical failure characterized by a percussive "shotgun blast" noise from the rear chassis, followed by an immediate, total loss of braking power (pedal to the floor) and a violent loss of directional stability. This incident represents an aggravated safety failure of known GMT900 platform defects. The technical chain of causality began with the factory exhaust manifold fasteners suffering a metallurgical shear, a universal defect documented under GM Bulletins 19-NA-218, PIP5075, and PIP4701. This shear created a high-velocity, high-heat exhaust leak directed at the brake master cylinder and vacuum assembly. This "heat soak" event compromised the engine-mounted mechanical Brake Vacuum Pump (Recall N192268490 / NHTSA 19V645) and destroyed the internal seals of the Master Cylinder (Special Coverage 15143 / NHTSA 11V599), resulting in total depletion of vacuum assist and hydraulic pressure. Simultaneously, the "shotgun blast" and violent swerve were caused by structural failure consistent with Rear Brake Caliper Bolt Fracture (GM 13247 / NHTSA 13V342) and Rear Axle Shaft/Pin Fracture (GM 14892 / NHTSA 14V819). This mechanical collapse caused the caliper to strike the wheel, resulting in a catastrophic rim blowout and immediate loss of tire pressure. Despite the vehicle having aftermarket long-tube headers installed, the root cause of the heat-related brake failure was the failure of the OEM GM manifold fasteners which snapped off in the cylinder head, as documented in the aforementioned bulletins. Under the Magnuson-Moss Warranty Act, the manufacturer remains liable for these pre-existing safety-critical defects. The vehicle is at Glenn Polk Chevrolet for a 901-series Product Allegation Investigation (Case #90199492). This report is filed to demand federal oversight into these life-threatening defects. The combo of failed fasteners, rim blowout, and compromised braking created a vehicle that was both unable to be steered or stopped

My GMC which is well cared for and only has 121,000 miles has a rusted through frame (mid-vehicle, left side) which has made the truck unsafe to drive. The steel used is inferior, my neighbor across the street also has this truck, 2 years newer, and is doing the same thing. As I have researched this issue I have found out that this is a critical failure of the GMC Sierra for several model years due to a failure to protect the steel used in northern states which compromises structural integrity. When Toyota had this issue, they stepped up and replaced the frames. General Motors, please tell me what you intend to do with this. It is a 5.3 Litre with 121,000 miles on it, in other words, still a baby for such a fine engine. This is not right. I am seriously discouraged. For my family, this is devastating. I still owe $2000 on this vehicle. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is not a safety item, but one that causes undue financial hardship for the owner. It is widely know that the dash on certain 2007-2014 GM vehicles (generally trucks and SUV's) is susceptible to cracking. This causes devaluation of the vehicle if not fixed and is reported to cost between $2,000-2,500 to repair. It is my opinion that the cause of this is the use of substandard parts by GM and they should issue a recall for the repair of the dash.

The main body frame is completely rusting through from under the drivers side door back past the fuel tank. It is rusting through on the passenger side as well. The large amounts of rust have caused other issues throughout the entire body of the truck as well as rusting of other components. The frame of this truck will need to be replaced as there is no way to repair it or the vehicle becomes scrap. This vehicle is available for inspection. These issues were not visible when purchased from the dealer. This issue gradually became visible after the rust and undercoating wore away that had been applied previous to our purchase from a known dealership.

Just noticed that the Frame is rusting badly. It is available for inspection upon request. I see that the Chevy Silverado has the same problem and that a recall exists for it, but not for the GMC Sierra, which is virtually the same truck. My safety or the safety of others can be put at risk if the frame were to fail. The problem has not been reproduced or confirmed by a dealer or independent service center. The vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. Unknown about any warning lamps, messages or other symptoms of the problem.

I had the leaf spring separated from rotted frame on the highway. I swerved and almost died. GMC must replace the frame to make this right. Soon I will have no truck after giving GMC so much money.

I towed a U-Haul trailer for four hours from Winter Springs, FL to Tallahassee, FL 08/18/2022. On the way back to Winter Springs, FL on 08/21/2022, I began to hear the dings and a message to service the trailer brake system. I had the vehicle looked at to determine the problem. The fuse was determined to be good, the ground wire was secure and not damaged, and the relay was functioning. I have been told that it may be a defective wire harness which could lead to other safety issues while operating the vehicle. The constant dinging and the blocking of vital messaging by the warning is a distraction and safety issue. A recall should be issued to correct this safety defect.

Risk: THE DRIVER MAY NOT BE ABLE TO MAINTAIN DIRECTIONAL CONTROL OF THE VEHICLE AND A CRASH COULD OCCUR WITHOUT WARNING.

Remedy: DEALERS WILL INSTALL A NEW REAR AXLE CROSS PIN FREE OF CHARGE. THE SAFETY RECALL BEGAN ON JANUARY 11, 2011. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463 AND AT THE OWNER CENTER AT WWW.GMOWNERCENTER.COM.

General Motors LLC (GM) is recalling certain 2009-2014 Chevrolet Silverado HD and GMC Sierra HD, 2009 GMC Topkick 5000, 6000, 7000 and 8000 Series and Isuzu F Series, and 2009-2018 Chevrolet Express, and GMC Savana vehicles, equipped with certain Plastic-Handle Fire Extinguishers or Push Button 'Pindicator' Fire Extinguishers.
