Immediately afterward, I lost complete control of the rear end, accompanied by violent clanking and grinding noises from the driveline area. The gearbox then stalled, leaving the vehicle disabled in the middle of the highway. Upon inspection, it was determined that a rear differential mounting bolt had sheared, causing the differential to shift violently out of position. This sudden movement resulted in the driveshaft breaking, which further destabilized the vehicle and led to a severe and immediate loss of control. This failure occurred without warning and created an extremely dangerous situation. The sudden loss of drivetrain integrity at highway speed placed both myself and nearby motorists at serious risk of a crash. A component as critical as a differential mount or driveshaft should not fail under normal operating conditions. This incident strongly indicates a serious design or manufacturing defect affecting the vehicle’s powertrain and structural safety. Requested Action: I urge the NHTSA to investigate rear differential mounting and driveshaft failures on this vehicle model. Such failures can lead to catastrophic loss of control, and immediate attention is necessary to prevent future incidents and ensure driver safety.
