GMC HUMMER PICKUP Recalls

The GMC HUMMER EV Pickup has 4 recalls spanning 2022 through 2026, with the most serious being a high-voltage battery pack sealing defect on 2022-2023 models where water can enter the battery enclosure, cause a loss of drive power, and raise the risk of a crash. The 2024 model year shares a separate propulsion concern: rear drive unit motors can have insufficiently insulated wires that contact each other, also cutting drive power without warning. On 2026 models, the front passenger airbag wiring can have an improperly crimped connection that prevents the airbag from deploying in a crash, leaving that occupant with less protection. The 2022 model year has an additional recall where a software fault can cause one or both taillights to go dark or stay partially lit at the wrong time, making the vehicle harder for other drivers to see and potentially sending misleading signals about braking or position.
