Open-data reference.
NHTSA Complaint about FORWARD COLLISION AVOIDANCE: DYNAMIC BRAKE SUPPORT/BRAKE ASSIST filed November 9, 2023
NHTSA complaint #1941841 (ODI reference 11554281) concerns a 2022 MERCEDES-BENZ C 300 and was filed on November 9, 2023. The owner reports the failure occurred on September 14, 2023. The vehicle had 20,000 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 forward collision avoidance: dynamic brake support/brake assist, 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 MERCEDES-BENZ C 300 cohort independently describe similar forward collision avoidance: dynamic brake support/brake assist 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 2022 MERCEDES-BENZ C 300 shows the complete component-level complaint distribution alongside any active investigations or recalls.
