The 2023 GMC HUMMER PICKUP has 2 recalls, the most serious involving the high-voltage battery pack, which may not be properly sealed and can allow water to enter, causing a sudden loss of drive power while moving.
The second recall concerns the front seatbelt buckles on both the driver and passenger sides, where the attachment bolts may not be tightened to the correct torque. A loose buckle can fail to hold the belt securely in a crash, reducing the restraint the belt provides to the occupant.
