Equipment problem #1

My 2017 Buick Lacrosse premium awd (116,220 miles) experienced a severe all-wheel-drive failure causing significant binding and a loud rumbling/clunking noise during sharp, low-speed cornering and acceleration. The vehicle has been officially inspected by two separate authorized manufacturer service centers. On September 25, 2026, a certified gm technician at advantage Buick GMC formally documented that the vehicle has a prominent rear drivetrain failure, identifying it as a "rear diff or driveshaft issue" that requires full component replacement. Prior to the complete mechanical failure, no warning lights or dashboard indicators illuminated. The binding symptoms appeared suddenly during normal city driving maneuvers. This drivetrain failure directly aligns with documented corporate engineering safety campaigns, specifically customer satisfaction program #16069 (propeller shaft/driveshaft c-clip disengagement defect) and TSB #18-na-049 (catastrophic twin-clutch carrier assembly failure). The failure of this component poses a severe, immediate driving hazard as a sudden disengagement of the driveshaft or differential lockup at road speeds can result in a catastrophic loss of vehicle control. General motors has ghosted my corporate case (#113840289) and refused to remedy this manufacturing vulnerability.

Equipment problem #2

My 2017 Buick Lacrosse premium awd experienced a sudden, dangerous mechanical failure of the accelerator pedal position sensor system while operating the vehicle under normal road conditions. The vehicle suffered an immediate loss of engine continuity and engine power, forcing the car into a hazardous low-speed limp mode while in active traffic. A certified repair facility inspected the vehicle, confirmed a complete failure of the internal pedal sensor circuit, and replaced the unit to restore safe operating throttle control. This specific electronic and mechanical defect represents a widespread manufacturing vulnerability that general motors has officially acknowledged under special coverage adjustment n182188250. This failure poses an immediate safety hazard to occupants and surrounding traffic, as a sudden drop in throttle response on highways or busy intersections leaves the driver unable to maintain safe traveling speeds or accelerate out of oncoming hazards. General motors has opened corporate case #113840289 regarding this failure but has failed to issue my safety reimbursement.

Equipment problem #3

The contact owns a 2017 Buick. When making a left-hand turn there is a rumbling sound coming from the right front, while driving approximately 20 miles. The bushing components are warned out. The vehicle was taken to a local repair shop, then to the dealer last week. The manufacturer was notified of the failure. No illumination lights on the dashboard about the failure. The repair shop diagnosed the failure; however, was informed GMC no longer carries the part.
