Elevated severity

What the defect is
General Motors, LLC (GM) is recalling certain 2022 GMC Hummer EV and 2023 Cadillac Lyriq vehicles. Certain connections within the high-voltage battery pack may be out of position or incorrectly welded, which can cause a loss of drive power.
Why it matters

Owner notification letters were mailed June 6, 2023. Owners may contact GM's Cadillac customer service at 1-800-458-8006 and the EV Concierge number: 1-833-HUMMER-EV (1-833-486-6373).
