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
