General Motors (GM) has announced a new recall affecting the Chevy Bolt EV and Chevy Bolt EUV models due to potential issues with the installation of battery fire detection software. This recall adds to a series of recalls impacting the Bolt EV and Bolt EUV, which previously underwent extensive recalls from 2020 to 2022 to replace faulty battery packs.
According to GM’s latest recall bulletin, certain units of the Bolt EV and Bolt EUV may have improperly installed diagnostic software designed to detect defective battery modules requiring replacement.

The safety concern revolves around the possibility that vehicles with incorrectly installed diagnostic software and defective battery modules could pose an increased risk of vehicle fires.
To resolve the issue, GM has instructed its dealers to reprogram the Hybrid Powertrain Control Module 2, the Battery Energy Control Module, and the Body Control module. The reprogramming process is estimated to take slightly over an hour for models produced between 2020 and 2021, and just under an hour for 2022 models.
The affected components include advanced diagnostic software crucial for the proper functioning of these control modules.
GM’s latest recall impacts Bolt EV units manufactured between 2020 and 2022, as well as Bolt EUV units from the 2022 model year. The exact number of affected vehicles has not been specified by GM at this time.
