The car abruptly died in motion. Backing up it died and locked itself in park. I had no way to move it out of the road. There were no warning lights nor did the car stutter or seem any different. I was also nightime making me invisible to other drivers. There was no way to shift the car from park to neutral to get it out of the road. After the incident Onstar sent an email with an error code P023F. The fuel module. I realized the 2021-2022 were under recall but not the 2023 i have. I purchased my 2023 in 2022 it likley was fitted with same modules that were under recall. I loved this car but that was such a frigntening ordeal I will no longer have it nor will i Purchase a GM product. I was told by the dealer sales manager that it wasn't under warranty and roadside assistance would not cover towing nor would the dealer cover repair. I reach out to another dealer and got a totally different answer. They fixed it but could not gurantee or actually even be convincing that it was a fix. I wan't other owners to be more aware of this issue to avoid tragedy. I do realize things tear up. But, this was totally preventable knowing the issue was never corrected.

There was no obstacle, impact, or external threat present. This uncommanded braking caused significant physical stress and injury to the occupants. Critically, multiple safety systems failed during the event: The seat belts did not lock, failing to restrain the occupants; The airbags did not deploy, despite the severity of the deceleration; no warning indicators or diagnostic alerts were present before or after the incident. These failures directly contributed to physical injuries, including TBI (concussion, spinal trauma, etc.) which required emergency medical treatment and ongoing care.
