The 2024 Cadillac Celestiq illuminated front grille does not comply with Federal Motor Vehicle Safety Standards (FMVSS) for exterior lighting. The advanced LED grille lighting system output exceeds or does not meet the required specifications, creating potential visibility and safety concerns for other drivers. GM and NHTSA received over 200 complaints from customers and dealers about the grille lighting behavior.

Common Symptoms

  • Excessively bright grille illumination
  • Grille lighting not deactivating properly
  • Other drivers complaining of glare from front of vehicle
  • Grille LEDs flickering or displaying unevenly
  • Recall notification letter from GM

How to Fix

Contact Cadillac dealer for free recall service. Dealers will perform a software update to recalibrate the grille lighting output. If hardware is faulty, the entire grille assembly will be replaced at no cost. As the Celestiq is hand-built at the Global Technical Center, parts availability may affect scheduling.

The Celestiq features a 55-inch diagonal LED display spanning the dashboard. Early production vehicles have experienced software issues including screen blackouts, display freezing, navigation system hanging, and OnStar connectivity problems. The 33-inch diagonal pillar-to-pillar display can occasionally go blank while driving. GM has released TSBs with software updates to address display reliability. These issues are shared with other GM Ultium-platform EVs like the Lyriq.

Common Symptoms

  • Main display screen goes black while driving
  • Infotainment system freezes and becomes unresponsive
  • Navigation system hangs or loses GPS signal
  • OnStar connectivity drops or becomes unresponsive
  • Climate control display shows incorrect information

How to Fix

Schedule a dealer visit for the latest software updates per TSB #23-NA-222. Perform a system reset by holding the power button for 10 seconds if display freezes. Ensure the vehicle has received all available OTA updates via Settings > Software Update. Contact Cadillac concierge for priority service scheduling.

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.

Typical repair cost:$0 - $400

As a hand-built, technology-flagship vehicle, the Celestiq experiences occasional software integration issues between its numerous systems including the 55-inch LED display, four-zone smart glass roof, and advanced driver assistance features. Individual systems may temporarily lose communication with each other, requiring a vehicle restart.

This issue also affects: GMC Yukon XL, Chevrolet Suburban, Chevrolet Equinox EV

Common Symptoms

  • Display panels showing incorrect information
  • Smart glass roof not responding
  • Driver assist features temporarily unavailable
  • System communication warnings

How to Fix

Given the Celestiq's bespoke nature, all service should be performed at authorized Cadillac dealers with Celestiq certification. OTA updates address the majority of software integration issues. The concierge service team can remotely diagnose many issues. Keep the vehicle connected to Wi-Fi for timely update delivery.

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.

This issue also affects: Chevrolet Malibu, Chevrolet Cobalt, Chevrolet SS

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.

Typical repair cost:$0 - $500
