COMPONENT: Vehicle Speed Control — Automatic Emergency Braking / Anti-Lock Braking System (ABS) COMPLAINT: I am filing this complaint to report a POST-REMEDY FAILURE of the repair performed under NHTSA Safety Recall 24V589 (GM Program #N242453471) on my 2024 Cadillac Lyriq AWD. RECALL REMEDY COMPLETED: My vehicle received the Electronic Brake Control Module (EBCM) software update on August 13, 2024, under GM Program #N242453471. The recall was marked "Complete" by the servicing dealership on that date. FAILURE INCIDENT: On March 15, 2026, at low speed (under 25 mph) on a dry surface, my Lyriq failed to activate its Automatic Emergency Braking system while approaching a stationary object. The vehicle did not decelerate or stop as designed. The ABS system appeared to release braking pressure rather than maintain it, allowing the vehicle to continue forward and strike the object. The front grille assembly sustained significant physical damage as a direct result. This failure is identical...

Electrical System
01/04/2026
I experienced a complete electrical failure in my 2024 Cadillac Lyriq that prevented access to the vehicle while an infant was inside. The incident occurred when the vehicle’s 12-volt battery system failed, causing a total loss of electrical power and rendering the vehicle completely unresponsive. As a result of this failure, all electronic entry systems stopped functioning and the exterior door handles remained in the locked position. There were no warning signs or error messages communicated from the vehicle. Because the vehicle could not be unlocked or accessed from the outside, an infant was trapped inside the vehicle for approximately 27 minutes. Cadillac has been contacted and they confirmed a faulty 12 volt battery and since then replaced the battery. The incident was recorded by home security cameras and documentation has been preserved. This event raises a serious safety concern. A failure of the 12-volt battery should not disable all methods of entry into a vehicle, particula...

Unknown Or Other

Component: Electronic Stability Control / Navigation / GPS Complaint: Since the February 2026 over-the-air software update, the built-in Google Maps GPS has been severely malfunctioning. The system consistently fails to update my vehicle’s location, showing me as stationary at my home address even after driving for 30+ minutes and 20+ miles away. This is not an intermittent glitch — it renders the native navigation system completely unusable after nearly every drive. Prior to the February 2026 update, the GPS functioned perfectly. The issue began immediately following that update and has persisted despite infotainment system resets and checking for further software updates. I am aware that GM has internally acknowledged this issue via Preliminary Information bulletin PIC6644 (issued February 2026), which attributes the problem to a “software anomaly” and confirms engineering is investigating. However, no fix or timeline has been provided to customers. A GPS system that does not reflect...

While slowly turning into a parking space at approximately 1 mph (?) the vehicle unexpectedly accelerated. The vehicle mounted the curb, and struck a a parked car and hit a brick retaining wall, causing damage to both. This all happened within a few seconds and there were no warning lights or messages before or during the accident. I was not injured and there were no other people present. The police were called and inspected the damages. The insurance company was contacted due to damages. No one was in the parking lot at the time. The manufacturer was notified and will inspect the car for cause/failure.
