VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
On September 9, 2025, while slowly turning into a parking space at approximately 7 mph, the vehicle suddenly experienced unintended acceleration. There were no warnings, alerts, or Safety Alert Seat vibrations prior to the surge. The vehicle rapidly accelerated forward, struck a parked car, went over a curb, hit a tree, and finally came to rest after colliding with the side of a building. GM has since taken possession of the vehicle for forensic analysis.

FORWARD COLLISION AVOIDANCE: WARNINGS, AIR BAGS
on Sept 23, 2025, I was rear ended by a driver going between 50-60 mph. I am concerned that some safety features were potentially not working at the time of the incident. I will detail the information below: Background / Original Service Issue: When I initially brought my vehicle to Titus-Will Chevrolet GMC Cadillac for service, I observed that multiple critical safety systems were nonfunctional, including, but not limited to: Forward collision alert sensor All cameras (rear, front, top down) Blind zone steering assist Lane departure warning and other associated warning sensors The dealership kept my car for two days and then informed me that a "module" needed to be ordered for repair, but stated that the vehicle was considered “drivable” and would call me when the part came in. I noticed some of the safety features had resumed working, however some were still non-functional. At no point was I told there were any potential safety risks, nor which safety systems were still not functional. I was not given any paperwork, as they were holding it until the module came in. Crash Event: On 09/23/2025 at 5:37 pm, I was involved in a crash. At the time of impact: The forward collision alert sensor did not function I received no warning of the impending collision No airbags deployed. This may have been directly related to the previously identified and unrepaired safety system issues.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, SERVICE BRAKES
At least 10 times over the past three months the vehicle’s feature of one pedal driving disengages without a reason or code. When the this happens the vehicle accelerates rapidly. This has happened on local streets and on the highway and often results in a near miss collision. I am concerned this will result in a serious injury or death.

SERVICE BRAKES
I was driving on Saturday September 3 at 5 pm over the Chain Bridge entering Washington DC. Traffic was heavy and the auto brake went on when I was about 15 feet from the car in front of me. I was using one-pedal driving and when I pushed on the gas slowly we started slowly moving forward. I was traveling around 3 or 4 miles an hour and the car would not slow down when I took my foot over the pedal. One pedal driving apparently stopped working. I then applied the brakes gently and the brakes did not work. I then pushed the brakes hard and still no brakes worked. I tried pumping the brakes and nothing worked. The car gently ran into the car in front of me causing no damage to the car in front and he kept on his way. My front grill was cracked and bumper was slightly damaged. The signal on the dashboard said parking brake engaged which it was not. While the auto safety brake engaged minutes earlier when it was not needed it did not work when the car was drifting uncontrollably into the car in front of me.

BACK OVER PREVENTION: WARNINGS, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
Backing out of driveway and screen went black and a collision occurred a second or two later. We have had the Lyriq in the shop multiple times for glitchy screens and screen going black but never has been fully resolved. I did recieve a recall letter (unfortunately I threw it away) but now it shows no recalls (strange). This black screen issue has been a problem since day 1 but now it has resulted in a collision. I have been unable to even back my car out of the garage when raining due to the sensitivity of the collision detect so there is NO excuse that it didn't alert. Cadillac has had the car since the accident and claim nothing is wrong with it and they are not responsible. I do not believe that. I have met with dealership GM who is looking into this further. I wanted to bring to the NTSB as this is 100% a safety concern. Thank God there wasn't a child on a bike or a baby in a stroller behind us. This didn't result in any human harm but the vehicle sustained damage that I believe was the direct result of malfunctioning technology on the car to prevent it.

POWER TRAIN, VEHICLE SPEED CONTROL, SERVICE BRAKES
While driving in one-pedal driving mode at the high setting, an error message appeared and one-pedal driving suddenly shut off and switched to a more standard drive mode where engine braking is disengaged. This happened while drive was engaged and stopped at a red light. The car briefly lurched forward and the car engaged an emergency brake to prevent the car from rolling into the vehicle in front of me. This incident was unpredictable and resulted in an unexpected change to the drive mode I had selected which could have lead to a collision.

FUEL/PROPULSION SYSTEM
Sudden Acceleration. -I was driving on a highway. I accelerated to pass a truck and when I took my foot off the accelerator the car continued to gain acceleration. The gas pedal had returned to a normal position but the car was still accelerating. I had to put full force on the brakes to get the car to stop. One of my passengers noted that there were flames around one of the brakes. I turned the car off and we waited approximately 45 minutes for the brakes to cool enough to proceed without further incident.

SERVICE BRAKES, ELECTRICAL SYSTEM, ENGINE
I was driving at a steady 65mph on a highway when the car suddenly surged and the message "1 pedal driving deactivated. Use brakes to stop." I stopped the car with the brakes and restarted it and reactivated 1 pedal driving. Note I was NOT using regenerative braking at the time. The car surged a few miles an hour, and in a heavy traffic scenario could have easily caused a crash.

WHEELS, SUSPENSION, STEERING
I purchased the 2025 Lyriq new on May 11, 2025. On May 30th with 5400 miles on the car, the front right wheel tie rod snapped off while driving causing the wheel to turn sideways. I was making a turn on a secondary sheet when it happened and was able to pull to the side of the road. Had I been driving on the highway at the time, I could have been killed or hurt another driver. I had the car towed to MacMulkin Cadillac on June 1. The dealership noted that it was bad welding and the car showed rust and rot in that area. It will be 30 days this Monday and no one from GM has been out to investigate.

ELECTRICAL SYSTEM, SERVICE BRAKES
Since a recent software update, vehicle will unexpectedly give multiple error codes, and disengage “one-pedal driving” mode. This happened recently when coming to a stop at a traffic light behind another vehicle. When coming to a gradual one-pedal stop, the one pedal driving mode unexpectedly disengaged, causing me to almost hit the vehicle in front of me. This error has occurred 5-6 times in the past 3 months.

VEHICLE SPEED CONTROL
One pedal driving switched to unavailable while driving - 24 Lyriq AWD I have seen this couple of times while driving now. I keep the one-pedal driving setting on High. I suddenly get an error on Side detection unavailable and One pedal driving turned off - use manual braking. I also feel a slight surge in acceleration while this happens, but I have been able to slow down and re-engage one pedal and it seems to work after that. I am concerned that I may bump into someone in front of me if this happens again, since it has happened a couple of times now!

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
Hi, this vehicle is owned by Surreal Development LLC. A company whom reverse engineers vehicle. GM has an issue in their Cadillac Lyriq's which causes a complete failure of the vehicle's communication systems without warning while driving. This issue appears to affect all Global B vehicles but it is most severe in vehicles with one pedal driving (Sierra EV, Lyriq, Blazer EV, Optiq, Silverado EV, Equinox EV, etc...) The error is likely within the vehicle's Serial Data Gateway Control Module but it is unclear. The vehicle recovers from the communication quickly (within seconds) but it causes long term adverse affects for that driving period. 1. The vehicle will light up with warnings (Service Traction Control, disengage super cruise, disengage ACC, etc...) 2. The driver's pedal will go into safety mode. 3. A "Service High Voltage" system warning may or may not appear. The safety concern is mostly in #2. When this happens it is very jarring to the driver as it drastically changes how the vehicle responds. While the vehicle may state one pedal driving is disabled many times it still indicates it is on within the controls (likely due to an error in the compounded communication fault). This can lead to the driver rear ending the vehicle in front of them or rolling over. The fault does not correct itself until the vehicle resets (powers off/on). The issue is common and affects many owners of the Cadillac Lyriq. The only diagnostic data we see are communication faults across many modules.

POWER TRAIN, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving my 2024 Cadillac Lyriq in rolling traffic, the vehicle abruptly engaged the brakes without warning or cause. The braking was so forceful I initially thought I had been rear-ended. Once the braking event ended, I began to accelerate—only to discover the vehicle had shifted into reverse without any input from me. This resulted in a rear-end collision. There were no alerts or dashboard warnings to indicate the gear change. I believe this may be related to a malfunction in the automatic emergency braking system or the shift-by-wire controller. This behavior presents a serious safety hazard and must be investigated. I have filed a report with Cadillac and will be taking the vehicle to a dealership for diagnostics and data log review.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
This is an update to my original NHTSA complaint submitted on May 5, 2025 (complaint number 11658852), regarding a complete electrical failure in a 2024 Cadillac Lyriq. While parked in a garage, the vehicle experienced a full shutdown—rendering all systems inoperable, including the door locks and windows. Most alarmingly, a [XXX] child was trapped in the back seat due to the doors being electronically locked and unresponsive. The dealership has since diagnosed the failure as a cable routed improperly near the steering column that had rubbed against a component and snapped. This severed connection resulted in the complete loss of vehicle power and emergency functions. Since that time, I have discovered multiple similar reports from other Lyriq owners online describing full system shutdowns, locked doors, and failures to start—many of which are shared on public forums such as Reddit [XXX] ). This suggests that this may not be an isolated case but rather a potential systemic defect in the Lyriq's wiring harness design or electrical architecture. I am extremely concerned that this failure mode could occur while driving, particularly at highway speeds, and would result in loss of steering, braking assist, and emergency exit options. I urge the NHTSA to investigate this issue further to determine whether a recall or manufacturer communication is appropriate. This vehicle is currently with the dealership, and I have refused delivery until GM provides formal safety assurances.
