Chevrolet Suburban 2023 engine shuts off after 30 minutes of operation and won't restart on Chevrolet Suburban

Some Chevrolet Suburban owners report experiencing issues with the engine shutting off after 30 minutes of operation and failing to restart. This problem may be linked to the GM Extended Parking feature, which automatically turns off the engine after a set time while parked, although it can be disabled. Additionally, if the vehicle is left running with the remote key inside, it may shut off sooner if parked on a hill or if fuel levels are low. Some owners have also noted that carbon build-up in the cylinder could contribute to the engine shutting off, although this is less common in modern vehicles due to improved fuel injection systems. To address these issues, it is advisable for owners to check fuel levels, ensure the key fob is present, and consider disabling automatic shut-off features. If the problem continues, seeking assistance from a certified mechanic or Chevrolet customer support is recommended.
