2025 Cadillac Lyriq Electrical System Problems

Car has been asleep after parking and will not wake up leaving all electrical components dead. GM has not been able to repair and unfortunately this has occurred 5 times including twice the month of March, 2026. Having a car parked in an unsafe location and not being able to move it very unsettling. After 30-60 minutes the car will start back up and operate normally.

Telematics module failed and the vehicle couldn’t connect to emergency OnStar services if involved in crash. GPS also doesn’t work with a faulty module. No cellular or WiFi connectivity. Car reroutes to somewhere without this module working. I’m paying for the OnStar subscription but with a faulty module it can’t connect. GM says part back ordered with no ETA. Thousands of people are reporting the same problem and it should be a recall at this point.

OnStar system on the vehicle is busted. Because of this the accident detection no longer works and the GPS is stuck in no mans land which makes it impossible to use their app to figure out charging percentage, how far and route to take to the nearest charging station.

The infotainment screen automatically adjusts its brightness based on readings from the ambient light sensor. However, during dusk and dawn, while conditions still appear relatively bright to the human eye, the sensor interprets the light levels as low and significantly dims the screen. As a result, the display can become so dark that it is nearly unreadable. This issue occurs even when the brightness control wheel is set to its maximum setting. The light sensor overrides the manual brightness adjustment, and the control wheel can only further reduce the brightness, not increase it. GM should provide an option to disable automatic brightness adjustment, or update the auto-brightness algorithm to prevent the screen from dimming excessively under such conditions.
