2026 Cadillac Lyriq Problems: 1 Known Issue

All 1 Known Issue

Filter:

On the 2023-2026 Cadillac Lyriq, lyriq owners report Super Cruise refusing to engage on mapped roads where it previously worked, going unavailable at startup and returning only after the car is parked and rebooted, and disengaging mid-drive with false lane messages such as 'lane ending' when the car is in the right-hand travel lane or 'driving in exit lane' when passing an off-ramp. Some owners report the feature stopped working entirely for days at a time. Because Super Cruise depends on the driver attention camera, the LiDAR map data delivered over the vehicle's cellular connection, and the forward camera and radar, the failure can originate in any of several modules - which is why dealers often find no stored fault. The behavior is reported across GM's Super Cruise fleet but is common enough on Lyriq to be a recognized owner complaint on the Cadillac forums.

Common Symptoms

Super Cruise unavailable at startup
Super Cruise will not engage on a mapped highway
False lane ending or driving in exit lane messages
Super Cruise disengages without driver input
Feature returns only after parking and restarting the vehicle
Super Cruise light bar stays dark

How to Fix

Have the dealer apply the latest Super Cruise, camera module and telematics software calibrations - GM has resolved a number of these cases with a software update, and OnStar/connected-services provisioning must be active for map data to download. Verify the windshield-mounted forward camera area and the driver attention camera lens are clean and unobstructed; an aftermarket windshield or tint band replacement without recalibration will disable the feature. Owners have reported restoring function with a hard reset by disconnecting the 12V negative cable for about 20 minutes. Persistent failures after software updates warrant camera module replacement under the bumper-to-bumper warranty.
