2015 MERCEDES-BENZ C300 — Complaint #2019610
Open-data reference.
NHTSA Complaint about SUSPENSION:SUBFRAME/MOUNTING BRACKET filed August 26, 2024
NHTSA complaint #2019610 (ODI reference 11610913) concerns a 2015 MERCEDES-BENZ C300 and was filed on August 26, 2024. The owner reports the failure occurred on August 26, 2024. The report was geocoded to Pennsylvania 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 2015 MERCEDES-BENZ C300 shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
My car (vin [XXX] ) a 2015 Mercedes C300 is experiencing the same premature rusting on the subframe. I was told that while a lot of Mercedes are covered, mine is not for some reason but I'm at the same risk for the subframe getting holes in it and wheels breaking off. I only have 78,000 miles on my car, only have it serviced at the dealer and it has been garaged parked. This type of damage is not typical for a car that has been this well cared for and for the amount it has been driven. I called Mercedes to honor the $5600 or to extend the warranty should it have to be replaced and they said to file a claim here. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
