Owners have filed 153 complaints
about the 2024 Cadillac Lyriq with NHTSA between 2024 and 2026.
The largest single group is the driver assist & collision avoidance.
Across this model's run it ranks 1 of 3 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 100
Against the median year of the Cadillac Lyriq. 50 means typical for this
model; 100 means roughly double.
Severity — 100
27.5% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 100
100% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

Electronic Brake Module Component Failure
On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles. These complaints allege a hard brake pedal, followed by a “Brake System Failure” message at start up or while driving. GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until th...
Recalls on the 2024 Cadillac Lyriq
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous

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.

VEHICLE SPEED CONTROL
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

On August 9, 2026, at approximately 3:40 a.m., while driving, the vehicle suddenly lost all propulsion and became completely disabled on the roadway. The vehicle remained powered on but would not move forward or backward. At approximately the time of the failure, Cadillac/OnStar Advanced Diagnostics generated a critical Electric Drive Unit warning instructing immediate service and reported diagnostic code P0A78. Additional vehicle diagnostic warnings involved the electric drive unit/high-voltage propulsion system. I immediately contacted roadside assistance but was unable to obtain a workable towing solution for several hours. The vehicle ultimately had to be privately towed and has remained undriveable since the incident. The loss of propulsion occurred unexpectedly while the vehicle was being driven, without advance warning that would have allowed me to safely plan for the vehicle to become disabled. I am concerned that the same sudden loss of propulsion could occur at higher speed, in traffic, at an intersection, or in another location where an unexpected loss of motive power could create a serious crash risk. The vehicle requires diagnosis and repair for the Electric Drive Unit/P0A78 condition.

This is about an issue with the ACC system. While driving with the ACC engaged, it will intermittently disengage and without notification. Then the vehicle applies hard braking. After many multiple occurrences, I now tap the brake pedal and apply acceleration. I can't tell you how concerning this can be while driving at interstate speed. Just the thought of a large truck behind me will put the fear into you. Additionally, I have been able to hear an electrical clicking noise emitting from the left side of the steering wheel. When this occurs the ACC is unavailable and/or unable to be selected. A barrage of notifications will appear saying the Adaptive Cruise Control Selected or Cruise Control Selected.

In the past 18 months the vehicle has experienced phantom breaking while driving 3 times. Each time there were no vehicles within 30 or more feet from the vehicle. All 3 times occurred while driving the vehicle and going between 20-40 mph. The vehicle engaged in an emergency break and stopped the car in the road. All three times could have resulted in a major accident as it occurred on busy roadways. This last time it happened in the middle of an intersection with no vehicles around me or behind me. This is a major safety concern and put my family and I in a potentially dangerous situation that could have caused major injuries to myself, my family and others around us. The vehicle is currently with Cadillac being inspected. During conversations with Cadillac they said this is a known issue and suggested that I turn the mechanism off and bypass the safety feature to avoid it from happening again. This is not a systematic fix. This is a bypass. We purchased the car for the safety and security and how sophisticated the safety mechanisms are and we have now been told as a suggestion to simply bypass it. This is very concerning on a national level of That the vehicle is known for doing this. We no longer feel safe in this vehicle The dealer has not confirmed if they have gotten it to duplicate.

STEERING
Component Involved: Steering Wheel Assembly (Super Cruise Steering Wheel Light Bar / Rim)Safety Defect Description:The plastic insert covering the Super Cruise LED light bar and the surrounding leather wrap located directly on the top rim of the steering wheel are breaking apart, peeling, and separating. This is an immediate and severe driving safety hazard. While executing turns and maneuvering the vehicle, the driver’s hands and clothing sleeves are actively getting caught and snagged on the exposed, broken plastic edges and peeling wrap on the wheel rim. This causes physical interference and sudden, unexpected entrapment of the driver's hand or clothing during active steering.Consequences of the Defect:This defect presents an imminent risk of a vehicle crash due to sudden mechanical restriction of the driver's hands. If a driver’s sleeve or fingers become trapped or snagged by the peeling steering wheel trim while negotiating a sharp turn, curve, or emergency evasive maneuver, they will be unable to smoothly rotate the wheel, leading to a direct loss of steering control.

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.

SERVICE BRAKES
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 dealerships. However, I have been told that the vehicle is “operating as designed,” despite the abnormal braking behavior. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by multiple authorized Cadillac dealerships and the issue has been escalated to General Motors. No resolution or fix has been provided to date. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There are no warning lights or messages associated with this issue. The problem occurs intermittently during normal driving conditions, particularly when transitioning from regenerative braking (one-pedal driving) to applying the brake pedal. The issue began shortly after taking delivery of the vehicle and has persisted since.

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.

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.

ELECTRICAL SYSTEM
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 cover, despite the fact that the OTA update process is the manufacturer's intended method for delivering safety-critical corrections and the failure to update is a vehicle deficiency, not a customer-caused condition. Due to these unresolved safety concerns, we have not been driving the vehicle. We do not have confidence that the vehicle is operating safely or as designed. We formally requested a repurchase from General Motors through the EV Concierge program (Case No. 87486271). That request was denied on March 14, 2026, citing two rationales: (1) the vehicle is out of warranty, and (2) system updates do not qualify for repurchase. We believe these rationales fail to account for the fact that the original safety complaints were filed during the warranty period and that the root issue is battery and system safety — not a routine software preference. We are filing this complaint to create a formal federal safety record and to request that NHTSA evaluate an investigation or recall.

VEHICLE SPEED CONTROL
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

ELECTRICAL SYSTEM
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, particularly when the design of the Cadillac Lyriq uses electronically actuated exterior door handles that remain recessed and locked without electrical power. This creates a situation in which occupants may be trapped inside the vehicle with no reliable means for outside access. The inability to unlock or mechanically access the vehicle during a power failure presents a significant risk of injury or death, particularly in situations involving children, extreme temperatures, or medical emergencies.
