VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

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 the vehicle’s actual location is a safety concern — particularly when relying on navigation for routing, hazard awareness, or emergency response. I am filing this complaint to ensure this issue is part of the public record and to urge NHTSA to monitor the scope of this defect across 2024 Lyriq vehicles

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, STEERING
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.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was traveling on the freeway at approximately 70 mph, at about 5:15 pm. I was not using cruise control. There was no one in front of me for maybe a quarter mile. Suddenly and without warning, the car slammed on the brakes. A yellow alert came up on the dash telling me the Forward Collision system had been activated. The red warning lights at the front of the dashboard (the heads-up display) also flashed. The road was dry, I was on an entirely straight section of road, and there were no shadows. Besides scaring me half to death, if someone had been immediately behind me, they could easily have slammed into me. The car has not been inspected by the dealer, etc. I believe OnStar should have a record of it happening, but I have not contacted them.

ELECTRICAL SYSTEM
After a manufacturer-initiated software/system update was performed on my 2024 Cadillac Lyriq approximately two weeks ago, the vehicle stopped charging and stopped generating heat. I brought the vehicle to Cadillac Norwood MA for diagnosis. The dealership informed me that a replacement part is needed, but the part does not currently exist and must be manufactured by General Motors. They could not provide any timeline for when the part would be available or when the vehicle would be repaired. The vehicle is being held at the dealership indefinitely. I have opened a case with Cadillac's EV Concierge and filed a formal complaint with them, but have not received a resolution or timeline. This vehicle is used professionally as a chauffeur vehicle and the inability to charge or heat the vehicle renders it completely inoperable and unsafe, particularly in Massachusetts winter conditions. A vehicle losing all charging capability and cabin heating after a software update represents a serious safety concern for EV owners

FUEL/PROPULSION SYSTEM
My car is equipped with a forward-facing camera, mounted on the forward area of the interior rearview mirror. Additional cameras are mounted on the front bumper, trunk door, and on the rearview mirrors on each side of the car. Various sensors mounted throughout both bumpers face the front, rear, and each side of the car. At the time of this incident all sensors and cameras were clean and free of obstructions, and software was up to date. I was driving uphill, negotiating a tight left curve at approximately 30 MPH in a rural, forested area in the Santa Cruz Mountains (California.) There were no other conveyances, objects, or obstruction on the roadway in front or behind me. The weather was clear and the daytime visibility was excellent. The road was dry and I estimate its gradient at 30%. As I was about to enter the curve, the vertical dirt hillside appeared ahead and directly in front of the forward-facing cameras and sensors, which I supose, detected this topography. With minimal pressure, I had my right foot on the throttle to keep the aforementioned speed while turning. The cruise control was not in use. As I began to turn, and while still facing the hillside, the throttle stopped responding and the car decelerated. Simultaneously, a warning appeared on my dashboard screen, indicating the forward collision warning system was unavailable. I fully depressed the throtle but instead of gaining speed, the car slowed down to 12 MPH as I completed the turn. In quick succession, I lifted my right foot of the throtle and depressed it all the way to the floorboard but the car did not accelerate. The car eventually regained forward acceleration when I had the throttle pedal all the way against the floorboard but despite this severe throttle application, the car only accelerated very slowly. Thereafter, the throtle resumed normal operation and I continued my trip over the hills and back. I believe I could have been rear ended during this scary incident.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS
On November 26, 2025, while traveling in stop-and-go freeway traffic, I experienced a severe braking failure that led to a rear-end collision. Despite applying maximum force to the brake pedal, the vehicle did not decelerate as expected. Objective technical evidence from the Bosch CDR report (Case #1105768) confirms a critical system failure: Extreme Driver Input: At -0.5 seconds before impact, Driver Applied Brake Pedal Pressure reached 10,935 kPa, representing a near-maximum emergency braking effort. Inadequate Response: Despite this peak pressure, the Vehicle Indicated Speed decreased only from 24 MPH to 22 MPH in the final 0.5-second interval. Data Discrepancy: The vehicle decelerated by 12 MPH (from 36 to 24 MPH) between -1.0s and -0.5s under lower pressure (7,695 kPa). However, when brake pressure was increased to its peak at -0.5s, deceleration effectively stalled. Electronic Anomaly: The Traction Control System (TCS) was reported as "Active" throughout the braking event, indicating potential improper electronic intervention. This vehicle has a history of significant electrical failures, including a total power loss on 10/15/2024 that required a high-voltage battery replacement. The failure of the braking system to respond to maximum driver input poses a catastrophic safety risk. I am requesting an investigation into the 2024 Cadillac LYRIQ's brake-by-wire and electronic stability control integration.

EXTERIOR LIGHTING
Driver Side Headlight erratic flicker while parked. Low beam unexpectedly turns on and turns off. Causes eyeball light sensitivity upon approach and could cause epileptic seizures for some. Problem has been replicated by dealer with video evidence provided by me. First attempt to fix was to provide software updates. That did not remedy. The second attempt was a full and complete inspection of all wires and modules which were in tact followed by a full replacement of the headlight assembly. This also did not remedy. The third attempt did not perform any action and to mark the concern as "operating as intended." No warning lamps or other indications except being in front of the vehicle while it occurs.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
My 2024 Cadillac EV is only 9900 miles. I was driving the car on Sunday Jan 11, 2026 with my family when we noticed smoke filled inside the cabin. My 3 children (a [XXX] , a [XXX] old, and a new-born who is [XXX] old) were in the car; they inhaled the smoke. We evacuated the car and called onstar for assistance - who towed the car. The smoke originated from the tailgate of the car. Alarmingly, just 3 days before this incident (Jan 8, 2026), I took the car to the local Cadillac dealership to complain about water intrusion in the left taillight that is in the liftgate. The service advisor created a repair order and sent me back saying it would take 10 days to arrive. Upon my specific inquiry, the advisor stated the car was safe to drive and assured me that I would not get a ticket. Since the event (5 days later) it was confirmed by the service advisor that the same water intrusion event lead to the electrical fire that burned a connector, a module, and multiple wiring components causing the fire.

ELECTRICAL SYSTEM
Telematics module failed and the vehicle couldn’t connect to emergency OnStar services if involved in crash. GPS also doesn’t work with a faulty module. No cellular or WiFi connectivity. Car reroutes to somewhere without this module working. I’m paying for the OnStar subscription but with a faulty module it can’t connect. GM says part back ordered with no ETA. Thousands of people are reporting the same problem and it should be a recall at this point.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Adaptive Cruise Control (ACC) caused dangerous unintended acceleration. This model of vehicle has an ACC that maintains following distance from a leading vehicle. It will decelerate to a full stop and will resume after a full stop while maintaining a proper following distance when prompted by a brief push on the accelerator. At the beginning of this incident, my ACC was set to about 40 MPH and I was following the car in front of me. At a traffic light, I came to a full stop behind the leading car for 10-15 seconds. At this point, I realized that the left lane turn signal changed to green which would allow me to proceed. Since there was no traffic in that lane, I decided to move from my lane to the open left lane. I turned the steering wheel to go around the car in front of me into the left lane. I then briefly touched the accelerator. The result was that the car accelerated at a high pace. Since my foot on the accelerator initiated the event, it took me a second or so to move my foot to the brake and disable ACC. During the acceleration, I was able to steer into the left lane and make the subsequent left turn without incident. I'm unlikely to make this mistake again. However, I'm pretty certain that this sequence is easily repeatable should you want to test for it. This ACC behavior seems dangerous. I expect that resuming ACC while following a vehicle will result in acceleration. But if the car is pointed in a new direction while it is stopped, it seems inappropriate to allow the ACC to resume by tapping the accelerator. A better ACC behavior would disable the"resume after a full stop" functionally if the wheel is turned more that a few degrees after an ACC controlled full stop.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
**2026 - Cadillac Lyriq One-Pedal Driving and Brake Defect** On November 4, 2026, at approximately 9:30 AM, I was driving my 2026 Cadillac Lyriq using the one-pedal driving feature while going below 20 miles per hour. Suddenly, the vehicle accelerated unexpectedly. I lifted my foot off the accelerator, but the car did not slow down despite the one-pedal driving being enabled. Within a few seconds, various warning lights appeared on the dashboard, including messages such as "One-Pedal Driving Unavailable," "Brake Assist Off," "Auto-Hold Unavailable," and "Steering Assist is Reduced - Drive with Care." Additionally, warnings for "Service Headlamps," as well as red or yellow indicators for "Parking Setting," "ABS," and "Ready," were activated. I made several attempts to apply the brakes, but they did not respond. I even tried to engage the parking brake, which also failed. Fortunately, I was lucky enough not to hit anyone or run over any curbs during this incident. The 2026 Lyriq that I purchased has fewer than 500 miles on it and has been at the dealer service center for over two weeks. This is a significant safety concern, and I believe Cadillac should take immediate action to address this issue.

UNKNOWN OR OTHER, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was driving about 40 MPH, message popped "camera blocked, clean front windshield" I did and the message cleared. A few minutes later it came back so I cleaned the windshield again. What happened next shocked me. Without any warning while traveling 30 mph the automatic braking system came on and stopped the car quickly. Thank God for my seatbelt! My backpack that was in the back seat came flying to the front. No warning at all! I called the dealer and brought the car t them. They told me they need to load new software in the car that would take 5-6 hrs. They did the software and told me that it should be all set now. I picked up the car and drove it home. A few days later an incident more alarming happened! I was at a traffic light, car stopped and auto hold when suddenly the car accelerated on its own. I pumped the break several times and the car eventually stopped. I was terrified. I called the dealer and brought the car there the next morning. Dropped it of Saturday morning. I call Monday afternoon and spoke with the service person and he told me they could not replicate what happened and that there were no bulletins from Cadillac. I asked how they tested it and he told me they took it for a ride and also looked for any errors recorded in the cars memory. I said it happened to me once in 2 days so taking it for a short ride will not necessarily repeat what happened. He said they will hold the car and look at a few more things today. I just spoke to the dealer and they told me they drove the car for 15 minutes and found no issues. They also said they are looking for any bulletins on the car. Not sure what the outcome will be but these 2 incidents could have both been very ugly and people could have gotten very hurt. I ask myself...should I be driving this car!

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
I am submitting this follow-up to document new information and continuing concerns regarding my 2024 Cadillac Lyriq EV, which experienced sudden unintended acceleration during a parking maneuver. GM and its claims administrator (ESIS) have now completed their review and issued a denial letter on October 31 2025, stating “no defects were found.” However, the denial included no supporting technical findings, analysis, or data explaining how that conclusion was reached. Despite multiple written requests, GM has not provided the following key event-data modules: – Brake System Control Module (EBCM/iBooster) export (brake pressure, pedal position, brake override flags) – Propulsion/Drive Control Module data (torque request vs actual torque and accelerator input) – Front Camera Module metadata (timestamps and event record IDs) Additionally, several data discrepancies remain unresolved — including mismatched timestamps between the ASCM and FCM reports and camera images that do not correspond to the actual crash scene. On October 29 2025, GM publicly announced Customer Satisfaction Program N252521980, covering certain 2023–24 Cadillac Lyriq and 2024 Chevy Blazer EV vehicles for a Brake System Control Module software update due to possible brake-control performance issues. Because my incident involved loss of braking response, this recall appears directly relevant. I have requested confirmation whether my vehicle is affected and whether this module was analyzed in GM’s investigation, but have not received a reply. I am requesting that NHTSA review GM’s handling of this case to determine whether the engineering review was complete and whether the vehicle’s BSCM or related systems could be implicated in unintended acceleration or brake override failures. GM Case #1092995 – Submitted to ESIS/GM Product Investigations Group. Thank you for your attention and for documenting this matter in the defect database.
