Discover which years of Chevy Bolt models had their batteries replaced due to defects. Find out about the recall process and warranty options for 2017-2019 and 2020-2022 models.
Chevy Bolt Battery Replacement Years
2017-2019 Models
The Chevy Bolt, a pioneering electric vehicle, has been at the center of several battery-related issues. For models produced between 2017 and 2019, there was a significant recall due to a manufacturing defect in the lithium-ion batteries. These batteries, supplied by LG Energy Solution, contained two major defects: a torn anode tab and folded separators. These defects could cause the battery to short circuit, potentially leading to a fire. As of September 2021, 13 fires had been identified as related to this recall, affecting over 141,000 vehicles.
2020-2022 Models
For the 2020-2022 models, the recall process was slightly different. Instead of replacing the entire battery pack, General Motors (GM) implemented a software solution to mitigate the risk. The diagnostic software limits the maximum charge level to 80% for up to 6,000 miles. If no issues are detected during this monitoring period, the battery is deemed safe for continued use. However, if problems are identified, the battery will be flagged for replacement. This approach aims to balance safety with the practicality of ongoing vehicle use.
Recall and Replacement Process
The recall and replacement process for Chevy Bolt EVs has been extensive. GM has halted production on all affected models until the battery issue is resolved. For 2017-2019 models, GM will replace all modules in the battery pack. For 2020-2022 models, only defective modules will be replaced. The work is done by Chevrolet dealerships at no charge to the owner. Additionally, GM has offered buy-backs and exchanges for other company vehicles on a case-by-case basis. Owners can contact their local Chevy dealership or GM’s concierge line for specific guidance on their vehicle.
GM’s Battery Defect Issues
The battery defect issues in the Chevy Bolt EVs are a result of manufacturing defects in the lithium-ion batteries supplied by LG Energy Solution. The primary defects include a torn anode tab and folded separators. These defects can cause the battery to short circuit, leading to a potential fire. The recall has been expanded to include all Chevy Bolt EV models from 2017 to 2022. The LG battery in the Chevy Bolt contains 288 lithium-ion cells, which are flooded with liquid electrolyte and encased in a flexible polymer pouch. The torn anode tab creates a projection in the battery pack, causing the anode to be closer to the cathode than intended, while the folded separator issue allows the anode to bridge the gap between it and the cathode, causing a short and leading to a potential fire.
Warranty and Compensation Options
General Motors has provided various warranty and compensation options for owners affected by the battery defect. The warranty covers any defects in materials or workmanship that affect the battery’s performance or cause premature degradation. If the battery capacity falls below a certain threshold, usually around 70% of its original capacity, GM will repair or replace the defective modules or the entire battery pack if necessary. Additionally, GM has agreed to a $150 million settlement with LG Energy Solution to compensate consumers harmed by the alleged battery defect. Notice of the settlement will be mailed to eligible class members within 60 days of the deal’s preliminary approval.
