Chevy Bolt EV Battery Replacement: GM Begins Shipping Modules

GM Resumes Shipping Replacement Batteries for Chevrolet Bolt EVs

General Motors has commenced the distribution of replacement battery modules to dealerships for the recalled Chevrolet Bolt electric vehicles. This follows postponements stemming from operational halts at several production sites due to the global semiconductor shortage.

Production Restart and Initial Timelines

The two battery assembly plants, located in Holland and Hazel Park, Michigan, recommenced operations in late September. Initially, GM projected shipments to dealers would begin around mid-October.

Prioritized Replacement Process

Replacement battery modules are being allocated based on “specific build timeframes.” This means vehicles manufactured during periods where defects are believed to be concentrated will receive priority.

The battery replacement procedure at a dealership is expected to take approximately two days. These new batteries are covered by an eight-year or 100,000-mile limited warranty.

New Diagnostic Software

Furthermore, GM is deploying updated diagnostic software by mid-November. This software will enable enhanced monitoring of EV batteries and will also be installed at dealerships.

Root Cause of the Recall

The recall was initiated after the identification of two manufacturing flaws: a torn anode tab and a folded separator. These defects, when occurring together, can elevate the potential for a fire incident.

Third Recall and Scope

This represents the third recall issued for the Bolt EV, and it is the most extensive to date. It encompasses all Bolt EV and EUV models manufactured from 2017 onwards.

Safety Recommendations and Owner Guidance

The announcement will undoubtedly provide relief to Chevrolet Bolt owners. The National Highway Traffic and Safety Administration previously recommended parking these vehicles a safe distance from residences due to the fire risk.

GM also cautioned owners against parking their Bolts within 50 feet of other vehicles, as reported by Bloomberg.

Financial Implications

The total anticipated cost for rectifying the defective Bolt batteries is estimated at $1.8 billion. GM intends to pursue reimbursement of approximately $1 billion from its battery supplier, LG Chem.
