All 4 Known Issues
On the 2023-2025 Cadillac Lyriq, the Lyriq's numerous electronic modules perform periodic wake cycles that can drain the 12V auxiliary battery when the vehicle sits for extended periods. Owners report dead 12V batteries after 5-10 days of sitting, preventing the vehicle from being unlocked or started.
Common Symptoms
- Dead battery after sitting several days
- Key fob won't unlock doors
- Vehicle won't power on
- Infotainment slow to boot after sitting
- 12V battery warning on app
- Multiple warning messages on startup after jump
How to Fix
A dealer software update addresses excessive module wake frequency. For long-term storage, connect a 12V battery maintainer to the auxiliary battery access point. GM released a TSB addressing this issue.

On the 2023-2025 Cadillac Lyriq, the rear camera and surround vision system intermittently displays a black or distorted image when engaging Reverse. The camera feeds may freeze, show the wrong camera angle, or display a "Rear Camera Unavailable" message. The issue is software-related and typically resolves after a vehicle restart.
Common Symptoms
- Black screen when in Reverse
- Distorted camera image
- Rear camera unavailable message
- Surround vision showing wrong angle
- Camera image freezes
How to Fix
Apply the latest OTA software updates. If the issue persists, the dealer can reflash the camera control module. Check for moisture in the rear camera housing — condensation can affect image quality. A hard reset of the vehicle (park, lock, wait 5 minutes) usually restores camera function temporarily.

On the 2023-2025 Cadillac Lyriq, the Lyriq range estimator significantly overestimates available range in cold weather, leading to range anxiety and potential strandings. The algorithm does not adequately account for cabin heating load, battery thermal management, and reduced battery chemistry efficiency in temperatures below 40F.
Common Symptoms
- Range drops faster than predicted
- Displayed range much higher than actual
- Significant range loss in cold weather
- Range estimate fluctuates widely
How to Fix
GM has released OTA updates improving cold-weather range estimation accuracy. Pre-condition the battery while plugged in before departing in cold weather. Plan routes with 30% additional buffer in winter. Use the heated seats and steering wheel instead of cabin heat to maximize range.

On the 2023-2025 Cadillac Lyriq, some Lyriq owners report intermittent charging issues including the charge port door not opening or closing properly, charging sessions stopping unexpectedly, and difficulty with certain DC fast chargers. The motorized charge port door can stick or fail to actuate in cold weather. Some Level 2 and DC fast charging stations have compatibility issues with the Lyriq's charging module. GM has addressed many of these with software updates.
Common Symptoms
- Charge port door won't open when pressed
- Charging session stops unexpectedly before completion
- Error message when attempting to charge at certain stations
- Charge port door stuck open or closed
- Slow charging speed on DC fast charger
How to Fix
Install latest OTA software updates which address many charging compatibility issues. For stuck charge port doors, the manual release inside the cargo area allows manual opening. GM dealers can recalibrate the charge port motor. For DC fast charging issues, try different charging networks - the Lyriq works best with EVgo and ChargePoint stations. Cold weather can cause the door to stick - a silicone spray on the door seal helps.

Parts and tips from 0+ owners who fixed this issue
- TipGM Service Campaign N232409680 covers free charge port housing replacement (part 86812523, revised design) for affected Lyriqs. Contact dealer with VIN to check eligibility. The revised design addresses the latch mechanism that fails to release the charging plug
- TipPrevent cold-weather charge port freezing by applying dielectric grease on door seal before winter. Manual emergency release cord located in cargo floor under left panel - familiarize yourself with its location before you need it. Some owners pre-heat cabin before unplugging in freezing temperatures
- NoteIf charging session stops unexpectedly, check for pending OTA updates first - several charging software updates have been released. Try a different charging network to rule out station compatibility. Pre-condition battery in cold weather before attempting DCFC - cold battery will either refuse fast charge or charge very slowly
- UpgradeAutomotive relay replacement set for common relay failures (Bosch Automotive Relay 5-Pin 12V)
- UpgradeDigital multimeter for diagnosing fuse, relay, and module electrical faults (Innova Digital Multimeter)
- UpgradeLevel 2 portable EV charger for reliable home or on-the-go charging (Lectron Portable Level 2 EV Charger)
