2024 CADILLAC LYRIQ — Complaint #2145976
Open-data reference.
NHTSA Complaint about FORWARD COLLISION AVOIDANCE: WARNINGS filed November 5, 2025
NHTSA complaint #2145976 (ODI reference 11697614) concerns a 2024 CADILLAC LYRIQ and was filed on November 5, 2025. The owner reports the failure occurred on September 3, 2025. The report was geocoded to Arkansas based on the filer's self-reported location. The affected component is categorized as forward collision avoidance: warnings, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: yes, fire: no, injuries: 1, fatalities: 0. A complaint that flags a crash, fire, or fatality is escalated on NHTSA's internal review queue and factors more heavily into any Preliminary Evaluation decision on this make and model. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same CADILLAC LYRIQ cohort independently describe similar forward collision avoidance: warnings failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2024 CADILLAC LYRIQ shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
I am submitting this follow-up to document new information and continuing concerns regarding my 2024 Cadillac Lyriq EV, which experienced sudden unintended acceleration during a parking maneuver. GM and its claims administrator (ESIS) have now completed their review and issued a denial letter on October 31 2025, stating âno defects were found.â However, the denial included no supporting technical findings, analysis, or data explaining how that conclusion was reached. Despite multiple written requests, GM has not provided the following key event-data modules: â Brake System Control Module (EBCM/iBooster) export (brake pressure, pedal position, brake override flags) â Propulsion/Drive Control Module data (torque request vs actual torque and accelerator input) â Front Camera Module metadata (timestamps and event record IDs) Additionally, several data discrepancies remain unresolved â including mismatched timestamps between the ASCM and FCM reports and camera images that do n
