2004 BMW 645CI — Complaint #949814
Open-data reference.
NHTSA Complaint about SERVICE BRAKES, HYDRAULIC:POWER ASSIST:VACUUM:HOSES, LINES/PIPING, AND FITTINGS filed November 16, 2012
NHTSA complaint #949814 (ODI reference 10484964) concerns a 2004 BMW 645CI and was filed on November 16, 2012. The owner reports the failure occurred on October 1, 2012. The vehicle had 150,000 miles on the odometer at the time of the incident. The report was geocoded to California based on the filer's self-reported location. The affected component is categorized as service brakes, hydraulic:power assist:vacuum:hoses, lines/piping, and fittings, 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 BMW 645CI cohort independently describe similar service brakes, hydraulic:power assist:vacuum:hoses, lines/piping, and fittings 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 2004 BMW 645CI shows the complete component-level complaint distribution alongside any active investigations or recalls.
