2025 MERCEDES-BENZ GLS 450 4MATIC — Complaint #2148215
Open-data reference.
NHTSA Complaint about STRUCTURE:BODY:ROOF AND PILLARS filed November 13, 2025
NHTSA complaint #2148215 (ODI reference 11699107) concerns a 2025 MERCEDES-BENZ GLS 450 4MATIC and was filed on November 13, 2025. The owner reports the failure occurred on November 13, 2025. The vehicle had 10,000 miles on the odometer at the time of the incident. The report was geocoded to Pennsylvania based on the filer's self-reported location. The affected component is categorized as structure:body:roof and pillars, 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: 1, 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 GLS 450 4MATIC cohort independently describe similar structure:body:roof and pillars 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 2025 MERCEDES-BENZ GLS 450 4MATIC shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2025 Mercedes-Benz GLS450.
