The 2022 GMC HUMMER Pickup has 3 recalls, the most serious involving the high-voltage battery pack, which can lose drive power unexpectedly and raise the risk of a crash.
Two separate battery issues affect this electric truck. In one, internal connections within the battery pack may be out of position and can cut drive power without warning. In the other, the battery pack enclosure may not seal properly, allowing water to enter and cause the same loss of drive power. The third recall involves taillight software that can cause one or both taillights to go dark or stay lit incorrectly, making the vehicle harder for other drivers to read in traffic.
