GM has issued a fix for certain 2023 Chevy Malibu units with potentially incorrectly seated body control modules, which also affects the 2023 Cadillac XT4.

A liquid spill in the rear seat, or water ingress from an insufficient body seam underneath the vehicle may allow liquid to penetrate the gateway control module, causing it to shutdown.
