2026 Cadillac Vistiq

need this case escalated immediately as a serious safety incident. [XXX] around While driving my 2026 Cadillac Vistiq on [XXX] around [XXX]pm doing approximately 45 MPH.  The vehicle suddenly and violently activated automatic emergency braking with no vehicle, pedestrian, animal, or obstacle anywhere near me. The dash displayed a warning similar to:“Front Collision detected Brake now” The braking was severe enough to throw me violently forward and backward in my seat, causing neck and back pain that has continued after the incident. This was not normal operation. The vehicle created a dangerous situation and could have caused a rear-end collision if another vehicle had been following closely. I am requesting: Full diagnostic retrieval of all Forward Collision / AEB event data Inspection and calibration of all front collision sensors, cameras, radar systems, and Super Cruise related modules Documentation of any known technical service bulletins, software issues, or engineering investigations related to phantom braking or unwanted brake assist activation Written confirmation of findings Immediate escalation to GM Technical Assistance and Cadillac Engineering I also request preservation of all vehicle event data associated with this incident. This event caused physical injury symptoms including neck and back pain consistent with whiplash-type force from abrupt emergency deceleration.

I believe the issue involved Super Cruise, forward collision warning, and automatic emergency braking systems. The vehicle is currently at the dealership and available for inspection. It has been there since 6/22/25 because the brakes and rotors are on backorder. While driving on the highway in the middle lane on a Sunday afternoon, I activated adaptive cruise after the vehicle had been parked for over 2 hours. After driving seven miles, the car suddenly jolted to a stop in the middle lane, as if we had been hit. We hadn’t—but cars were forced to swerve around us at highway speeds. If traffic had been heavier, this could have caused a serious crash. I exited safely to a mall parking lot, where the car began smoking from the brake area and gave multiple warnings, including “Reduce braking to avoid overheating.” The car remained parked, but the messages continued. A tow truck driver later said the brakes appeared to have caught fire because of how charred they were. I have video of the smoke and warning messages. This is a major safety concern. No. The issue has not been reproduced due to the parts being unavailable. The car has remained at the dealer since 6/22/25. Not to my knowledge. Only the dealer has had physical access to the vehicle since the incident. Just before the event, I saw a brief message on the screen, possibly “Auto Collision Not Engaged.” I had used Super Cruise previously without issue. No prior warning signs appeared before this failure.
