The vehicle systems named most often in GMC Hummer EV Pickup complaints (one complaint can name several).
In the owners’ own words, as filed with NHTSA. Unverified reports; NHTSA removes personal details before publishing.
Automatic Emergency Braking engages when no object is present to hit. This has happened twice at lower speeds (roughly 20-30 mph). Parked cars present on side of road. Dangerous to driver and passengers as well as anyone behind the vehicle. Dealer hasnât yet inspected the vehicle but that is pending scheduling.
While driving on a public road, the vehicle suddenly shut down and rebooted itself. Motive power was lost during the event. This has happened at least a dozen times during normal driving, including while transporting a child. Video of an occurrence was recorded. The vehicle is a 2025 GMC Hummer EV with approximately 10,400 miles and has been in service about eight months. This creates a serious safety risk. A sudden loss of propulsion and system reboot while moving can leave the driver unable to maintain speed or control in traffic and increases the risk of a crash. The vehicle has also had other problems that have been reported to an authorized GMC dealer: a front tire worn to the cords a…
While traveling with my wife and two toddlers over the July 4th holiday weekend, the 12 volt battery on my 2025 GMC Hummer EV failed completely at approximately 7,500 miles and five months of ownership. The vehicle would not accept a jump start and was disabled where it sat, stranding my family. AAA installed a replacement 12 volt battery roadside at a cost of $600. Following the battery replacement, a Service High Voltage System warning appeared on the dash and remained on, and the air conditioning system stopped functioning entirely. This occurred in Southern California summer heat with two small children in the vehicle. The HVAC loss and the high voltage system warning persisted for week…

Black hood center molding broke off, hit the windshield and blocked driver view.
While driving, a strong wind blew and flipped up the black hood insert of Hummer EV truck. It can cause severe damage to the windshield and harm the driver and front passenger.
My 2023 GMC Hummer EV 3X has experienced repeated thermal-protection failures in the high-voltage battery and drive-motor cooling system, causing the vehicle to enter limp mode and drop to as low as 12 mph without warning. Stored fault codes: P0C12, P0C13, P2EE0, P2EE1 (battery and drive-unit overheating). A sudden, unannounced drop to 12 mph in a 9,000-lb EV is a serious safety hazard â on highways it creates rear-end collision risk, in intersections it leaves the vehicle stranded in traffic, and on remote roads it can strand the driver with no safe shoulder. Visit 1 (Covert Buick GMC of Bee Cave, TX): 02/09/2026â03/24/2026, 43 days out of service. Repairs: replaced both EV coolant pu…

Source: NHTSA Office of Defects Investigation public data (complaints, manufacturer communications, investigations), model years 2010 and later. Had a safety problem? Report it to NHTSA.
In complaints filed with NHTSA for model years 2022–2026, owners most often name: electrical system, structure, fuel/propulsion system. 14 complaints are on record.
No. A complaint is an unverified report from an owner. A technical service bulletin (TSB) is the manufacturer telling dealers how to fix a known issue; it is not a safety recall and is usually covered only under warranty. A recall is a formal safety action, and its repair is free.
File a vehicle safety complaint at NHTSA.gov. NHTSA reads every report, and patterns of complaints are what open defect investigations and, eventually, recalls.
