Some ’20-22 Bolts were resold with the promise of a new battery with new warranty en route others got the battery if they were lucky. So the obvious problem here is that GM was initially offering new batteries to all 2020-2022 Bolt owners, and then slow-rolled the replacement. Jaguar, who use similar LG cells in its Magna-produced i-pace issued a similar remedy last week. 2017-2019 Bolt owners should still receive a replacement battery. It is important to note here that this only applies to 2020-2022 Bolt owners. Until yesterday, that was taking the form of replaced batteries however. Instead they were promised fixed defective modules. GM also clarified that ’20-22 Bolt owners were never promised new batteries. Owners of certain 2020-2022 model year Bolt EV and EUVs, can start to schedule installation at their Chevy EV dealer June 13, 2023. The software is free and will need to be installed by their dealer via a brief service appointment. If an anomaly is detected, the software will alert the owner via a message on the driver information center and the owner should then contact their dealer to schedule a battery or module replacement. The software will continually monitor the battery to detect any potential anomalies and, if none are detected after approximately 6,200 miles (10,000 km) of use, the battery will automatically return to 100% state of charge without a return trip to the dealer. GM will provide owners of certain 2020-2022 Chevrolet Bolt EV and EUVs covered under a previously announced recall a new advanced diagnostics software. Presented with the above, a GM spokesperson told us: Here are screen grabs from the old (left) – and new as of May 2023 – documents: Old Remedy New Remedy The new document is here The older documents are here and here In all other vehicles, the remedy is the installation of advanced diagnostic software that will monitor battery performance and identify defective battery modules that require replacement.” In typical GM weasel word (or lack thereof) style the May 2023 document doesn’t highlight the change or explain what made the change possible. The latest is from May 2023 and says the remedy is “In certain vehicles that GM has determined may contain defective battery modules, the remedy is the replacement of the vehicle’s high-voltage battery pack. (Links to follow) The first two are from 2021 and say the remedy is battery replacement. There are 3 of these reports on the NHTSA website for the battery recall for 2020-2022 Bolts. A commenter, Dave Salman, found out that GM sneakily updated its recall documentation to the NHTSA:Īnother document GM submits to NHTSA is a 573 report. Or perhaps they started changing in May when GM updated its recall documentation. Once the safety recall is removed I should be able to buy my car at the end of the 36 month lease in August or earlier. They told me that GM tested the removed batteries on 2020-2020 Bolts and found that most were not found to be defective so they did not need to be replaced. I made an appointment with my dealer to get this software installed next week. Once it passes these tests they will remove the safety recall on your vehicle. They will install software that puts the vehicle back to allowing 100% charging and it monitors the car to see if there are any defects in the battery pack. I got a call today from the Chevrolet Concierge letting me know that GM has come up with a software fix instead of replacing the main battery on 2020-2022 Bolts. See our Bolt Recall Guide for all the details here. The battery replacements were to take place on all pre-existing Bolts with the affected LG battery packs. GM initiated a recall in 2021 after a small number of Bolts high voltage batteries caught fire. As you might imagine, affected Bolt owners are up in arms. Instead, a software diagnostics tool would be used to verify if the batteries had problems before a replacement would be performed. 2020-2022 Chevy Bolt owners, starting yesterday evening, began receiving messages that their high voltage battery/module replacements would no longer be happening.
