Nhtsa defect report (initial portal filing) manufacturer target: general motors (gm) filer: joseph r. Fears classification: mechanical defect & administrative evasion narrative for submission I am filing this formal defect report regarding a catastrophic, systemic safety failure present in the 2025 Chevrolet Traverse architecture (VIN: 1gnevgrs1sj123332), manufactured by general motors. The vehicle was originally purchased at autonation timonium. The safety defect and telemetry proof on March 18, 2026, the vehicle suffered a total failure of the transmission and drivetrain systems. It was immediately surrendered to preston Chevrolet, where it remained completely out of service for 34 consecutive days. Gm's own onstar diagnostic telemetry automatically dispatched critical fault alerts while the vehicle was stranded, explicitly logging the following irrefutable failure codes: dtc u1962 (pcm - engine and transmission system): warning stated: "system transferring power to the drive wheels not performing as expected. " this indicates a catastrophic decoupling or failure to transfer motive power. If this failure occurs at highway speeds, it results in a total loss of propulsion, creating an extreme rear-end collision hazard. Dtc u0452 (viu - onstar system): a simultaneous failure in the wireless communication and safety system, meaning that when the drivetrain catastrophically fails, the vehicle's automated emergency sos and crash-reporting telemetry is actively blocked or compromised. Elevation to administrative evasion general motors and its authorized dealer network were provided with formal written notice of this defect. The 30-day statutory right to cure window fully expired without any mechanical resolution. Rather than deploying engineering solutions to rectify the severe safety defects they released into the public domain, gm has instead deployed aggressive legal maneuvers designed to evade accountability.
