The automatic emergency braking system suddenly engages without any obstacles/pedestrians in the roadway causing the vehicle to completely stop. The vehicle is at the dealership at this time; it is unknown if the dealer can confirm the issue. The vehicle has not been inspected by the manufacturer. There was a warning light flashing directly before the incident(s).

Automatic emergency braking activated on three separate occasions when there weren’t any reasons for it to engage, additionally if there were any cars behind me I would have been rear ended since they would not have anticipated me stopping so suddenly.

While driving on the highway at approximately 65-70 mph the Automatic Emergency Braking system engaged for no apparent reason, no vehicles were around or near our vehicle. The sudden and unexpected braking could have cause a major accident resulting in serious injuries or worst had our vehicle been rear ended.

I was stopped at a red light, it turned green and I proceeded to drive forward through the intersection when all of a sudden the automatic braking system engaged brining the car to an immediate stop in the middle of the intersection. My passenger and I were thrust forward into the steering wheel and dashboard respectively. The car behind me hit me. Both cars sustained damage. There was nothing in front of me that should have caused this safety system to engage.I beleive they call this phantom braking. Because I had just started up from the light, my speed was slow and we sustained no injuries. However if that happened on the freeway I travel quite frequently, I would have been killed. I am so stressed about driving this car, I asked cadillac to disengage it. Gm and cadillac both did inspections and cadillac said there is nothing wrong with the braking system. I don't understand the gm report and have asked for an explanation. My understanding when I bought the car last year was that the "smart system" was for forward emergency braking for vehicles ahead not behind the car. When I drive out of my garage and it just starts to rain, the automatic braking system abruptly stops my car and I cannot get out of the driveway until the car gets fully wet. I was told this can happen sometimes. I asked cadillac to adjust the sensors and they said they are not adjustable. Something is terribly wrong with this system.

While backing up I had situations where the automatic brakes would engage although there was no obstruction behind the car. To stop this from happening, I had to turn this feature off. I brought the car in for service (Ed Morse Cadillac in Delray Beach, Florida) and was given a Cadillac Service Bulletin that acknowledged this was a problem with 2023-2025 cadillacs and there was no fix for this problem. They suggest that I do what I had done- turn it off. I feel this is not an adequate response. This is a very important safety feature that helps to insure that motorists will not hit objects while going in reverse, and more importantly will not hit a person or child, possibly causing severe injuries. Cadillac should find a way to fix this issue before someone is killed because of this.

I am submitting this complaint to report a significant safety system failure in my 2025 Cadillac XT4 during an accident that occurred on April 12, 2025, in Dallas, Texas. During the incident: •The Anti-lock Braking System (ABS) did not activate, and I was unable to stop in time to avoid a collision. •Neither the driver nor passenger airbags deployed, despite sufficient impact that should have triggered deployment. •OnStar Automatic Crash Response did not activate, nor was I contacted by any emergency response service through the vehicle. None of the vehicle’s safety systems functioned during this event, despite being standard factory-installed features. My XT4 had no warning lights or diagnostic messages indicating any malfunction prior to the crash. This failure closely resembles previous complaints noted in the federal safety agency filings (e.g., ABS sensor failures, OnStar module failures, and the 2025 XT4 passenger airbag recall). I am extremely concerned that this may point to a broader defect within the model line’s safety infrastructure, including collision sensors, electronic communication systems, or airbag deployment logic. I respectfully request that the federal safety agency investigate whether a defect exists in the braking or airbag systems, particularly where no safety features activate in a crash. I would be willing to provide repair records, crash photos, and allow the vehicle to be inspected if needed. Thank you for your attention and for helping to ensure driver safety through proper oversight.

I was driving with my husband and daughter, when all of a sudden, the vehicle braked out of nowhere (twice) with no one in front of us and the Emergency brake notification flashed on the windshield. Thankfully no one was directly behind us or else my daughter, who was in the back seat, could have been seriously injured. We had the vehicle towed to the dealership and they said this was not common but in fact it is. This vehicle is not safe to drive.

The AEB system engaged when it should not have with no obstructions on [XXX] . I violently jerked, I thought I hit something but did not. The safety of myself and a person following me would have been been compromised. If someone was closer to me in the rear they would have hit me. My GM Onstar light turned to red and Onstar contacted me to see if I was ok. The problem has been confirmed by Faulkner Cadillac in Bethlehem, Pa. False Automatic Emergency Braking-Bulletin [XXX]. When the occurrence happened the Automatic Emergency Braking warning came on in my Driver Information Center. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
