I put the car in reverse and released the parking brake. The car started to move backwards. However, the back passenger door was wide open, and the passenger was standing outside the car in the path of the open door. The door hit a guide wire running from the top of a power pole to the sidewalk beside the car. The wire pulled the door backwards, destroying it. This was fortunate. Without the wire in the way, I would’ve had not heard the crashing of the door and would have continued to drive over the person standing beside the car as the passenger door knocked him down. The indicator that the door was still open is so small on the gauge cluster that I couldn’t see that the door was still open when I put the car into reverse. There was no audible warning that I was about to move before all doors were closed, and the emergency braking didn’t stop the car from moving. The passenger’s leg got pushed sideways under the open door. Had the guidewire not pulled the door backwards and caused so much noise that I stopped, the door would’ve broken the passenger’s leg and potentially pushed him under the rear passenger side tire.

My 2024 Cadillac LYRIQ generated the following High Voltage Battery fault codes via On-Demand Diagnostic: U2B4A, U2B4D, U2B50, U2B53, U2B56, U2B59, U2B5C, U2B5F, U2B62, U2B65, U2B68 — all under module VIC - Lithium-Ion Battery. Multiple codes are flagged "Service Right Away" indicating an active fault in the high voltage propulsion battery system. I brought the vehicle to Lindsay Cadillac, Alexandria VA [XXX] ) on [INSERT DROP-OFF DATE]. As of today [INSERT TODAY'S DATE], the vehicle has been sitting at the dealership for [X] days with ZERO repair action taken. The service manager has stated he does not know what to do, has no timeline, and cannot provide any answers. GM Technical Service Bulletins PIP6009B and 25-NA-044 specifically cover these exact DTCs and provide a documented repair procedure. The dealer has failed to follow or initiate this procedure. No loaner vehicle was provided despite this being a warranty repair on inoperative vehicle. I have been forced to rent a vehicle at $125/day out of pocket. I have an open Cadillac Concierge case number [93707662 #]. Cadillac Concierge was unable to reach the dealer's service department by phone. I have escalated in writing to GM's executive office including [XXX] and [XXX] with no resolution. This is a high voltage battery fault on an all-electric vehicle flagged as "Service Right Away" severity. The vehicle remains unrepaired, the dealer is unresponsive, and GM's own customer service cannot reach the dealer. This represents both a safety concern and a complete failure of the warranty service obligation. I am requesting NHTSA investigation of both the underlying battery defect and the dealer's failure to act on a known TSB.

Sunroof/moonroof cracked without any impact or signs of impact.

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 in nature to the defect described in Recall 24V589 — specifically, the ABS falsely activating and releasing braking pressure during low-speed operation on a dry surface — despite the recall remedy having been applied and certified complete ten months prior. SAFETY CONCERN: The software remedy applied under Recall 24V589 did not correct the defect on my vehicle. This raises serious concerns about the effectiveness of the EBCM software update as a remedy across all affected vehicles. If other vehicles received the same software update and the defect persists, there is a significant ongoing safety risk to the public. I am requesting that NHTSA: Investigate whether the Recall 24V589 remedy (EBCM software update) has been effective across all affected vehicles Determine whether a supplemental or revised recall remedy is necessary Require GM/Cadillac to cover physical damages resulting from this post-remedy failure I have also contacted Cadillac Customer Care direct

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 despite multiple repair attempts.
