Bulletin No.: PIC6449B Published date: 05/25/2023 Preliminary Information PIC6449B Process to Replace Battery Packs Which Need Repair - Customer Vehicles Only Models Brand: Model: VIN: Model Years: from Engine: to Transmissions: Chevrolet Bolt EUV 2022 - 2022 All All All All Chevrolet Bolt EV 2017 - 2022 All All All All GMC HUMMER EV 2022 - 2022 All All All All Involved Region or Country North America Condition A Bolt EUV, EV, or HUMMER EV may require a battery pack repair outside of the recall process to correct a battery related DTC or a damaged battery pack. Cause Bolt EUV/EV: Under normal circumstances, GM would encourage repair of the battery pack instead of replacement. Bolt EUV/EV and HUMMER EV: With the current recall bulletins in place, replacing the pack assembly during this time is the most expedient way of repairing the customer's vehicle. Bolt EUV/EV - Updated Internal repair: Replacing the A28 contactor assembly (RELAY, HIGH VLTG BAT DISCONNECT RELAY) is an allowable individual repair as of May 2022. This part is not on restriction. Note: This Updated process is for current customer owned vehicles only, this does not apply to dealer owned (new), Used vehicles or Buy back vehicles at this time. Those vehicles will be added at a later time. Correction: Bolt EUV/EV and HUMMER EV: To request a battery pack outside of the recall process, please initiate a GM Technical Assistance Center case. Proof of the need to repair must be provided to TAC, such as a GDS2 session log showing the battery-related DTC, or a picture of a damaged pack (if applicable) and its BIN label (left side of pack Bolt EV/EUV) and & (rear of pack HUMMER EV). TAC will review the case and approve a pack if the above criteria are met. If the vehicle has not yet had a pack replaced for its applicable recall, the VIN will be opened for the recall automatically and the dealer may order a pack from the Bolt EV Global Connect app and complete the pack replacement recall for the customer. IVH will show the VIN recall status opened within 7 days. Initiating a TAC case is the way to kick o this process. This process is temporary and will be discontinued at a point in the future when repairs for the pack are available once again.
