During a recent dealership inspection at approximately 40,400 miles, an authorized GM service center (Jack Hanania Chevrolet) discovered that the vehicle's rear differential was completely \"bone dry\" of gear oil . Because there is no history of catastrophic fluid leaks, seal blowouts, or external damage, this strongly indicates that the rear differential was either never filled or improperly filled with lubricant at the factory during vehicle assembly. This issue originally presented as a persistent drivetrain vibration, shudder, and \"skipping\" sensation starting as early as 12,000 miles . I brought the vehicle to the dealership for this exact vibration at approximately 21,000 miles. The dealership misdiagnosed the issue as \"low transmission fluid\" (despite the transmission being a sealed system) and failed to inspect the rear differential . The symptoms persisted until the vehicle was immobilized in November 2025, which is when the bone-dry rear differential was finally discovered . A vehicle operating with an empty rear differential poses an extreme and immediate safety hazard. The lack of lubrication causes severe internal heat and friction, inevitably leading to a sudden, catastrophic mechanical seizure of the rear axle . If the rear wheels lock up while driving at highway speeds, it will cause an immediate loss of vehicle control, resulting in a high-speed collision. I urge NHTSA to investigate GM's factory fluid-fill procedures and quality control for 2019 Silverado differentials to prevent a fatal lock-up event for other drivers on the road.","products":[{"type":"Vehicle","productYear":"2019","productMake":"CHEVROLET","productModel":"SILVERADO 1500","manufacturer":"General Motors, LLC"}]}]}
