## Narrative
On [XXX], my wife was driving our 2024 Cadillac Lyriq RWD (VIN: [XXX] ) in stop-and-go traffic on [XXX]  at 5-10 MPH. She was maintaining a safe distance when the truck ahead suddenly stopped. She pressed the brakes firmly, but the vehicle failed to stop, resulting in a collision.  Despite full brake application, the car did not stop as expected. The Automatic Emergency Braking (AEB) and Forward Collision Alert (FCA) systems did not activate. No alerts or braking assistance occurred, even though these safety features were enabled.  Her passenger witnessed her screaming that the brakes were not stopping the car. The crash caused front bumper damage, and a police report was filed.  Investigation & GM’s Response GM inspected the vehicle but refuses to provide testing details. The Crash Data Report does not show any recorded braking event or safety activation, despite my wife pressing the brakes. GM has not explained:  Why the brakes failed to stop the vehicle. Why AEB and FCA did not activate. Why no braking data was recorded despite the collision. Safety Concerns My wife is now afraid to drive the vehicle and refuses to continue driving it after repairs. I may be forced to break my lease or sell the car due to this serious safety concern.  This raises major safety risks for other Cadillac Lyriq owners, especially with known braking-related recalls on 2023 and 2024 models.  Request for Investigation I urge NHTSA to:  Investigate braking system failures in the 2024 Cadillac Lyr
