-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.

My 2023 traverse rs experienced a loud grinding noise and sudden loss of power, almost like i slammed the brakes on while moving. I was in the middle of the road and i could have been rear ended. 10/12/26. This matches the GM recall N222389310 exactly but my vin is currently excluded. I am also experiencing a heavy vibration since 9/13/2026 similar to diving over rumble strips, it is intermittent and will not throw a code, its been to the GM dealership where new transmission fluid was put in, however started again, that did not solve the problem . GM does not have a recall for torque converter clutch they are aware and had put out a technical service bulletin TSB-23-NA-072.

Sep 18, 2026Fuel/propulsion system
The high-pressure fuel pump/fuel delivery system failed on my 2023 Chevrolet Traverse at approximately 47,480 miles. The vehicle generated diagnostic trouble code P0091. An authorized Chevrolet dealership inspected the vehicle and documented that the high-pressure fuel pump was âinternally faultyâ 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 started consuming oil at around 25-30k miles. Now adding 3Q between the recommened oil change period. First realized this when driving on road trip and the engine oil low warning triggered. Driving at night on a interstate - had to pull off and find a safe place to check it. Could of been stranded with an engine failure in the middle of nowhere. Dealer confirms the issue, but GM says 1Q per 2000mi is "normal" in their world. Refuses to do anything when losing 1/2 your oil every oil change internal...
