Cadillac Lyriq battery connections may cut drive power

high How serious is it? About this label

Serious: GM did not tell owners to stop driving, but suddenly losing drive power in traffic can lead to a crash, and GM thought the risk important enough to send owners an extra warning letter, so schedule the inspection soon.

What's wrong, in plain English

Some 2023 Cadillac Lyriq and 2022 GMC Hummer EV models have connections inside the big high-voltage battery pack that may be out of position or welded wrong. A bad connection there can cut the power that drives the wheels, so the vehicle can lose the power to move while you are driving. Dealers will open up and inspect the battery pack and replace the whole pack if they find a problem. GM mailed owners a separate letter explaining the safety risk.
