ABS Randomly turns on with the traction control light… All windows except for driver window will not go down and sometimes it does not unlock or lock sometimes. It started the beginning of 2022 and has got worst over the years. It is available for inspection. Safety has been and issue because whenever it rains it can lose control on the road haven’t had the money to fix it so don’t really drive it right now.

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

The contact owns a 2011 GMC Sierra equipped with Nitto tires, Tire line: N/A, Tire size: 285/55r20, DOT number: 73BM, and Nitto tire Tire line: Ridge Grappler Tire size: 285/55r20 and DOT number 73 BM The contact stated that while driving at an undisclosed speed the contact noticed the vehicle would vibrate. An independent was made aware of the failure and informed the contact that the tire failed due to the lump found on the front driver's tire. The tire was replaced. The contact stated the failure recurred. The contact inspected the tire and the rear passenger tire also experienced the same failure. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 265, 000 and tire failure mileage was not included.

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)

Over the past few years squirrels have eaten through the fuel line of the truck just above the fuel tank multiple times. As soon as the ignition switch is turned on fuel gets pumped out very near the exhaust system. The driver may not notice anything wrong immediately causing a very real fire risk. Today is the fourth time I have experienced this issue with this truck.

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.

My truck keeps getting code p2138, when it happens I get reduce engine power alerts, check engine light and it stalls. It's been doing it for years now. It's very unsafe, last time it it did it I was on the freeway and had to pull to the side, but the car has no acceleration so vehicles are passing me by at 75- 80mph and I almost had a very bad accident.
