Chevrolet Electrical Recalls Include Bolt Battery Fires and Power Loss
⚠ 5 carry a park-outside (fire risk) advisory.
Bolt battery fire concerns recur most often in these Chevrolet electrical notices. The 2020 and July 2021 notices address 2017-2019 Bolt EV vehicles within their stated coverage; the August 2021 notice covers certain 2020-2022 Bolt EV and 2022 Bolt EUV vehicles. June and October 2024 notices cover those later model years with diagnostic-software installation problems. Other defects are distinct: 2019-2020 Silverado 1500 cable connections, optional rear-HVAC wiring on 2003-2023 Express Cutaway incomplete vehicles, 2018 Malibu injector-control software, and medium-duty truck ABS indicator programming. Additional notices address the 2020 Corvette front trunk lid, 2024 Trax instrument display, and rear-drive-unit wiring on 2024 Blazer EV and Silverado EV vehicles.

Can you keep driving? What the notices say
Five listed Bolt recalls carry park-outside instructions: November 13, 2020; July 23, 2021; August 20, 2021; June 27, 2024; and October 31, 2024. The 2020 notice specifies limiting charging to 90% or parking outside until its software update. July 2021 specifies parking outside after charging and avoiding indoor overnight charging; August 2021 specifies parking outside after charging. Both 2024 notices specify parking outside and away from structures after charging until repair. None carries a stop-driving instruction. For the remaining listed recalls, the notices do not tell owners to stop driving.
What the free repair involves
Explicitly free remedies include sealing Express rear-HVAC circuits, reprogramming the Malibu ECM, updating Corvette body-control software, updating Trax VCU software by dealer or OTA, and replacing affected Blazer EV/Silverado EV rear drive units. The Silverado cable notice describes inspection, cleaning, reattachment, and replacement of damaged components; its supplied remedy excerpt does not establish cost.
