2023 Chevrolet TraverseRecalls, problems, MPG & safety

“-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 -”
