On the 2024 Cadillac Celestiq, 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.

On the 2024-2025 Cadillac Celestiq, the advanced active suspension with independent wheel control occasionally miscalibrates, producing ride quality inconsistencies over certain road surfaces. The system may feel overly stiff on rough roads or too soft during cornering. The four-motor active suspension requires precise calibration for optimal performance.
Common Symptoms
- Inconsistent ride quality
- Overly stiff ride on rough roads
- Body roll in corners
- Ride height warning message
- Clunking from suspension
How to Fix
Dealer software updates address calibration algorithms. The suspension system can be recalibrated using GM diagnostic tools. Ensure all ride height sensors are functioning properly. The system learns road conditions over time, so initial rides in a new area may feel less refined until the adaptive algorithms adjust.
