NHTSA complaint #2073714 (ODI reference 11648185) concerns a 2020 CADILLAC XT4 and was filed on March 13, 2025. The owner reports the failure occurred on March 5, 2025. The vehicle had 83,376 miles on the odometer at the time of the incident. The report was geocoded to Georgia based on the filer's self-reported location. The affected component is categorized as service brakes, hydraulic:foundation components:master cylinder, 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 service brakes, hydraulic:foundation components:master cylinder failures, defect investigators have grounds to open a PE and request manufacturer data.
