2023 Chevrolet Traverse problems

“-The Torque Converter Clutch (TCC) inside the automatic transmission is malfunctioning. It is experiencing a known defect outlined in GM Service Bulletin 23-NA-072. The vehicle is still being driven and is available for inspection upon request. -The transmission violently shudders and vibrates under light acceleration at low speeds (such as pulling out into traffic, merging, or navigating intersections). This violent, unexpected shaking creates a distraction, mimics the feeling of a blown tire or driving over a rumble strip, and causes hesitation in acceleration, which creates a safety hazard when merging with oncoming traffic. -The problem has been consistently reproduced by the owner. It matches the exact diagnostic criteria of GM’s active Technical Service Bulletin for TCC shudder. -No, it has not been inspected. - No check engine lights, warning lamps, or dashboard messages have appeared. The physical symptom is a severe mechanical shudder/vibration at low acceleration speeds, which first began appearing at approximately 75,000-80,000 -”

An authorized Chevrolet dealership inspected the vehicle and documented that the high-pressure fuel pump was “internally faulty” and required replacement. The vehicle and/or failed component may be available for inspection upon request, depending on whether the dealership retains the component after replacement. This failure presents a significant safety concern because the high-pressure fuel pump is responsible for maintaining proper fuel delivery to the engine. Failure of this system can result in hesitation, reduced engine performance, loss of power, stalling, or failure to start. A sudden loss of engine power while traveling at highway speeds, entering an intersection, or merging into traffic could increase the risk of a crash and endanger vehicle occupants and other motorists. The malfunction was confirmed by an authorized Chevrolet dealership through diagnostic testing. The dealership identified code P0091 and specifically documented the high-pressure fuel pump as internally faulty. To my…”
