2011 MERCEDES-BENZ C300 — Complaint #1850817
Open-data reference.
NHTSA Complaint about SUSPENSION:SUBFRAME/MOUNTING BRACKET filed October 30, 2022
NHTSA complaint #1850817 (ODI reference 11491541) concerns a 2011 MERCEDES-BENZ C300 and was filed on October 30, 2022. The owner reports the failure occurred on October 29, 2022. The report was geocoded to New York 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 2011 MERCEDES-BENZ C300 shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
While driving home last night (with passenger), I experienced a sudden pull to left and wobble\oscillation of the car when I made steering corrections to prevent vehicle from going into oncoming traffic. Car seemed to behave normally except whenever I applied the brakes. I proceeded home, where I inspected for the obvious such as brake calipers, pads. rotors etc. Then I removed the rear left tire. This was due to a clunking sound that seemed to come from that area. Everything looked OK until I saw a front lower suspension part (a plastic covered pressed metal strut connecting the lower part of the wheel\rotor assembly to large U-shaped frame member which had multiple welded attachments and brackets) just hanging there unattached on one (forward) end. The bracket it was bolted to was just sheared off. Looked like it rusted to the point of finally tearing itself off of the frame. There was no warning of this condition either by sensors/lights/etc. or the performance of the vehicle w
