2007 CADILLAC V-SERIES — Complaint #659384

Open-data reference.

NHTSA Complaint about SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DIFFERENTIAL PROPORTIONAL VALVE filed February 28, 2008

NHTSA complaint #659384 (ODI reference 10219373) concerns a 2007 CADILLAC V-SERIES and was filed on February 28, 2008. The owner reports the failure occurred on February 16, 2008. The vehicle had 22,000 miles on the odometer at the time of the incident. The report was geocoded to Texas based on the filer's self-reported location. The affected component is categorized as service brakes, hydraulic:foundation components:differential proportional valve, 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: 0, 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. No VIN was supplied by the filer, so this complaint contributes to model-year trend data but cannot be tied to a specific vehicle.

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 V-SERIES cohort independently describe similar service brakes, hydraulic:foundation components:differential proportional valve 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 2007 CADILLAC V-SERIES shows the complete component-level complaint distribution alongside any active investigations or recalls.
