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 replace defective battery modules. Until replacement battery modules are available, General Motors recommends the following:
1. Enable "Target Charge Level" using the vehicle's infotainment centre to limit the state of charge to 90%. If you are unable to make these changes, or do not feel comfortable making them, you should visit a dealer to have these adjustments completed.
2. Charge your vehicle more frequently and avoid depleting the battery below approximately 113 km (70 miles) of remaining range, where possible.
3. Out of an abundance of caution, park your vehicle outside immediately after charging and not leave vehicle charging indoors overnight.
