NHTSA Complaint #11654492 — 2024 CADILLAC XT4

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 NHTSA 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 NHTSA 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.
