This recall was replaced by Transport Canada Recall No. 2021-449.
On certain vehicles, the high-voltage battery could overheat when it is charged to over 90% of its capacity. As a result, the battery could create smoke or heat, which can melt or damage the battery and nearby parts.
A battery that overheats can create a fire risk.
General Motors will notify owners by mail and instruct you to enable "Hilltop Reserve" (for 2017-2018 models) or "Target Charge Level" (for 2019 models) using their vehicle's infotainment centre. This will limit the battery charge to 90% until you can take the vehicle to a dealer for an update of the battery monitoring software. The dealer will also replace battery module assemblies that fail a diagnostic test.
Important - General Motors recommends that you should park your vehicle outdoors immediately after charging and not leave your vehicle charging overnight, even after this update is completed.
