An update to the Vehicle Interface Control Module (VICM) may have disabled the cell balancing function causing a low-voltage condition.
If the voltage drops, the vehicle may lose propulsion, increasing the risk of crash.
What to do
GM will notify owners, and dealers will reprogram the VICM, free of charge.
The manufacturer has not yet provided a notification schedule.
Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 18215.
