What's wrong?
The high-voltage battery pack in the 2022-2023 Lyriq and Hummer EV Pickup stores the energy that drives the electric motors. Inside that pack, battery modules and their connections have to be positioned and welded correctly so power moves through the pack as designed. The vehicle depends on those connections to deliver steady propulsion power.
On affected vehicles, certain connections inside the battery pack are out of position or incorrectly welded. GM traced the issue to battery module test equipment after software maintenance temporarily disabled the pass/fail logic used during end-of-line testing. That allowed suspect modules to pass through production. If one of those connections does not carry power correctly, the vehicle can lose drive power.
Owners will see a battery warning light and a "Service High Voltage System" message in the instrument panel. A "Charging Disabled" or "Vehicle Will Not Restart" message will also display.
Who's affected?
The scope spans a Cadillac electric SUV and a Hummer electric pickup, both with the same high-voltage traction battery.

What happens at the repair
At the dealer, a Hummer technician inspects the high-voltage battery pack connections and replaces the battery pack if the inspection finds the affected condition. Parts and labor are free under recall 23V367. Out-of-pocket repairs already paid are handled through warranty coverage, not through a separate reimbursement program, because the covered vehicles are under warranty.
