The Celestiq features a 55-inch diagonal LED display spanning the dashboard.

These issues are shared with other GM Ultium-platform EVs like the Lyriq.
Common Symptoms

The Celestiq shares the GM Ultium platform with the Lyriq and Blazer EV, and inherits the 12V auxiliary battery drain issue common to these vehicles. The vehicle electronics draw power from the 12V battery even when parked, and the high-voltage system may not always recharge it properly. If the 12V battery drains below a critical threshold, the vehicle may fail to start or exhibit various electronic malfunctions. This is exacerbated by the Celestiq's extensive electronic systems including the 55-inch display and advanced lighting.
Common Symptoms
- Vehicle fails to power on after sitting for several days
- Warning messages about low 12V battery on display
- Electronic systems behaving erratically on startup
- Key fob unable to communicate with vehicle
- Delayed response when pressing start button
How to Fix
Keep the vehicle plugged in when parked for extended periods to allow the HV system to maintain the 12V battery. If the 12V battery dies, use the designated jump-start terminals under the hood. Ensure the latest software update is installed as GM has released calibration fixes. Consider a trickle charger for long-term storage.
