2022–2026 GMC Hummer EV Pickup common problems and fixes
Certain 2022–2023 trucks were recalled because water can get into the high-voltage battery pack (the fix is a new pack); on owner forums, roof panel leaks on early trucks and 12-volt battery faults come up most.
What owners should know
Covers 2022–2026 · Electric (two or three motors) · Updated 2026-10-06
The Hummer EV Pickup is a large electric pickup with two or three motors, removable roof panels, four-wheel steering and a big Ultium battery pack.
We counted only 14 owner complaints filed with NHTSA for 2022–2026 Hummer EV pickups (retrieved October 5, 2026; each complaint counted once), far too few to show a pattern, partly because few were sold. Starting with 2024, NHTSA files some Hummer EV records under a plain "Hummer EV" name that also covers the Hummer EV SUV, so we checked every complaint's VIN: all 14 belong to Hummer EV Pickups, and none had to be left out. Recall lists under that plain name can still include SUV-only recalls. Complaint counts show what owners report most often, not how many trucks have a problem.

Common failures & how to fix them

Water can get into the high-voltage battery pack (2022–2023)
Dealer jobSigns: Warning lights or a warning message, a truck that won't start, or a loss of drive power. There may be no warning beforehand.
Fix: Covered by GM recall 22V771000 (GM N222380031) on certain 2022–2023 Hummer EV Pickups: the battery pack enclosure may not be sealed properly. The repair replaces the high-voltage battery pack at a GMC EV-certified dealer, free. Until it's done, GM says the truck can be driven and charged normally, but don't drive through water more than 24 inches deep. Recalls cover only specific trucks, so check this VIN at nhtsa.gov/recalls to see if it's included and whether the repair was done.
May be covered free by recall 22V771000. Check the VIN at nhtsa.gov/recalls.
Water leaks from the removable roof panels
Dealer jobSigns: Water dripping at the roof seams or windshield pillars, or wet headliner and carpets.
Fix: Have a GMC dealer find where the water is coming in (roof panel seals, seams or drains). On HummerChat, owners report redesigned roof support bars and seals fixing the leaks.
12-volt battery faults
Dealer jobSigns: 12-volt battery warnings, a truck that won't power on, or screens and systems acting up.
Fix: Have the 12-volt battery tested and the fault codes read, and make sure software updates are installed. Owners on forums report updates fixed modules that didn't shut down and drained the 12-volt battery on early trucks.
