Condition
GM recovers a small number of electric vehicle battery packs from customer-owned
vehicles in the field each year for further engineering study and analysis. This program
helps GM improve future EV products, analyze the performance of the battery packs in
customer driven EVs, and proactively identify and correct potential issues before they can
impact battery or vehicle performance. GM selects batteries for participation in this
program based on various engineering criteria, including manufacturing data, vehicle
location, vehicle mileage, and battery charging behavior. The customers involved will be
contacted proactively by GM to visit a GM EV certified dealer for a battery pack
replacement under warranty.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job
properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
