Open-data reference.
NHTSA Complaint about EXTERIOR LIGHTING:HEADLIGHTS:DAYTIME RUNNING LIGHTS:BULBS filed October 2, 2025
NHTSA complaint #2135901 (ODI reference 11691036) concerns a 2019 CADILLAC XT4 and was filed on October 2, 2025. The owner reports the failure occurred on June 15, 2025. The vehicle had 75,000 miles on the odometer at the time of the incident. The report was geocoded to North Carolina based on the filer's self-reported location. The affected component is categorized as exterior lighting:headlights:daytime running lights:bulbs, 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: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. 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 XT4 cohort independently describe similar exterior lighting:headlights:daytime running lights:bulbs 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 2019 CADILLAC XT4 shows the complete component-level complaint distribution alongside any active investigations or recalls.
