2012 MERCEDES-BENZ C300 — Complaint #1764954
Open-data reference.
NHTSA Complaint about SUSPENSION:SUBFRAME/MOUNTING BRACKET filed August 25, 2021
NHTSA complaint #1764954 (ODI reference 11430454) concerns a 2012 MERCEDES-BENZ C300 and was filed on August 25, 2021. The owner reports the failure occurred on August 14, 2021. The vehicle had 120,000 miles on the odometer at the time of the incident. The report was geocoded to Ohio based on the filer's self-reported location. The affected component is categorized as suspension:subframe/mounting bracket, 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 C300 cohort independently describe similar suspension:subframe/mounting bracket 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 2012 MERCEDES-BENZ C300 shows the complete component-level complaint distribution alongside any active investigations or recalls.
