The high voltage battery could catch fire when charged to full or nearly full capacity.
A battery fire increases the risk of injury.
What to do
GM will replace defective battery modules free of charge.
Owners should take the following interim steps:
Activate either the Hill Top Reserve (2017 and 2018 models) or
Target Charge Level (2019 models) feature in their vehicle to limit the charge level to 90%, charge their vehicle after each use, avoid depleting the battery to 70 miles range remaining, park outside after charging, and do not charge the vehicle overnight.
Interim letters notifying owners of the safety risk are expected to be mailed September 6, 2021. A second letter will be mailed once the final remedy is available.
