2024 Cadillac Lyriq Complaints

What component or system failed or malfunctioned, and is it available for inspection upon request? The issue involves the Anti-lock Braking System (ABS) and the transition between regenerative braking and friction braking in my Cadillac Lyriq (RWD). The ABS engages unexpectedly during normal braking conditions when using one-pedal driving. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? The unexpected ABS activation creates inconsistent and unpredictable braking behavior, including a pulsing sensation and reduced braking confidence. This affects the driver’s ability to modulate braking smoothly and predict stopping distance, increasing the risk of a collision, especially in normal traffic conditions where consistent braking response is critical. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue has been reproduced during multiple visits to authorized Cadillac dealership...

The vehicle has experienced repeated failures of the infotainment and display system, including the screen going blank and displaying “no content available” while functions such as Apple CarPlay are actively in use. The issue affects the ability to control media and view system information from both the main display and steering wheel controls. The vehicle has undergone multiple repair attempts, including replacement of the human machine interface (HMI) module and radio module, as well as repeated programming. Despite these repairs, the issue continues to reoccur, including immediately after the most recent repair. The condition is intermittent and difficult to duplicate, and a field service engineer has been unable to consistently reproduce the issue. The dealership has indicated there may not be a current fix and that resolution could depend on a future software update. This ongoing failure of critical display and control systems raises safety concerns and has not been resolved d...

We own a 2024 Cadillac Lyriq EV. We began experiencing safety concerns related to battery performance and overall vehicle reliability during the active bumper-to-bumper warranty period. These concerns were reported to an authorized GM dealer, Napleton Cadillac, prior to warranty expiration. Service records at Napleton Cadillac document the history of these complaints. The vehicle has been unable to process required over-the-air (OTA) software updates through GM's intended automated update process. During a dealer visit on February 17, 2026, at GM's direction, the Napleton Cadillac service technician confirmed that the vehicle had multiple open notices and that our reported concerns are consistent with known issues affecting the 2024 Cadillac Lyriq across multiple units — indicating this is not an isolated occurrence. The dealer advised that correcting the update failure would require approximately five hours of manual labor at an estimated cost of $1,250 — a cost GM has declined to c...
