2012 Audi Q7 STEERING,SUSPENSION,SERVICE BRAKES

On or December 5th, 2025 (4 days after taking possession of the vehicle, I experienced a sudden and severe steering system failure while driving. When turning the steering wheel (even slightly), the vehicle produced a loud buzzing/grinding noise and the steering effort increased significantly, creating an immediate safety hazard. Because the steering issue worsened quickly and made the vehicle difficult to control, I stopped driving and brought the vehicle to an authorized Audi dealership for inspection. The Audi dealership confirmed the steering failure was caused by a major power steering system defect, including active power steering fluid leakage from the steering rack area consistent with internal seal failure, and the power steering pump being faulty due to fluid loss. The dealership advised replacement of the power steering rack and pump and stated the vehicle was unsafe to test drive due to its condition. During the same inspection, the Audi dealership also identified additional serious safety-related defects, including a brake system condition where the brake pedal slowly sinks toward the floor when pressure is applied (indicating a braking system performance failure requiring brake fluid exchange and further diagnosis if unresolved). The inspection also documented multiple additional mechanical and safety concerns requiring extensive repairs, including suspension and drivetrain defects and other conditions indicating the vehicle was not roadworthy as sold. The vehicle remains available for inspection. This incident involved a sudden loss of steering assist and braking abnormalities that could lead to loss of control, crash risk, and injury to the driver, passengers, and other motorists.
