Component: Steering & Suspension / Upper Ball Joint--Catastrophic Structural Failure: On [XXX], at highway speeds on [XXX], the left front wheel completely separated from the upper control arm due to an instantaneous upper ball joint failure. The left tire turned sideways, locking the steering system. The vehicle was equipped with factory stock suspension and GM 24-inch rims-Pre-Accident Diagnostic Negligence: The vehicle exhibited a severe front-end "thumping noise" within the warranty window. It was brought to Lucas Chevrolet on [XXX] (31,901 miles) and Burlington Chevrolet on [XXX] (with a "Service 4WD" light active). Both certified facilities failed to perform physical tear-downs or torque checks, releasing a hazardous vehicle. Burlington Chevrolet is currently ignoring all voicemails requesting my service records-Dangerous 20-Hour Roadside Abandonment: Chevrolet Roadside Assistance left the driver stranded on a live highway shoulder for 2.5 hours in rush-hour traffic and darkness. Due to unsafe conditions, the driver was forced to leave the vehicle for an unassisted tow. Because roadside repeatedly sent wrong equipment for a collapsed suspension, the vehicle sat overnight and was not delivered to the dealer until 21 hours later-Evidence Preservation Hazard: Dealership Director Bob called the consumer to explicitly direct them not to hire legal counsel. Following this call, the dealership unilaterally changed writing from a "Customer Satisfaction Guarantee" to a "Goodwill Repair" and Service Manager Denny DiRenzo levied a $150 core charge on the steering rack. This fee acts as a financial barrier to force the surrender and destruction of the physical evidence. GM is also refusing to inspect the remaining three ball joints. Investigate Manufacturing Defect: Cross-reference this structural collapse with active wheel hub bolt recalls, Wave the $150 core, investigate parts, buy back, create recall for hub bolts and upper control ar INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 5

Component Affected: Suspension / Steering / Wheels / Front Hub Assembly Description of the Safety Defect & Incident: Proactively brought the vehicle to two separate authorized Chevrolet dealerships due to a severe thumping noise when turning the steering wheel. I explicitly stated to service staff that the vehicle felt unstable and unsafe to drive. Both dealerships performed inspections, stated they found no issues, and released the vehicle back to me. Shortly thereafter, while driving at full highway speed during rush hour, the front-end suspension/hub assembly suffered a catastrophic structural failure. The front driver-side wheel completely turned sideways and broke off, causing the vehicle to drop directly onto the pavement and skid violently across the highway. I narrowly avoided a multi-vehicle collision and managed to slide the vehicle to the shoulder. The wheel hub assembly completely separated from the steering/suspension structure, rendering the vehicle totally disabled. This failure matches the catastrophic hazards associated with recent GM front-wheel hub bolt relaxation and separation safety notices.

2025 CHEVROLET SUBURBAN HIGH COUNTRY. Vehicle is parked in my garage. Went out in the AM and the engine only cranks, will not start. Called On Star for roadside assistance. Sent a tow truck, the vehicle could not be towed due to the electronic transmission. There is no way for an owner to place the transmission in neutral. Vehicle is stuck in my garage. GM customer service referred me back to roadside assistance who for the second time stated that they could not help me. This is a serious issue. The fact that the transmission can NOT be shifted into neutral unless the engine is running is a very serious safety concern.Called GM helpline a second time. They said that I should call for a tow on my own. Waiting for the selling dealer to call me back. Vehicle is currently stuck in my garage and GM does not care.
