2018 CHEVROLET SUBURBAN — Complaint #2173951
Open-data reference.
NHTSA Complaint about Other/I am not sure filed February 5, 2026
NHTSA complaint #2173951 (ODI reference 11716042) concerns a 2018 CHEVROLET SUBURBAN and was filed on February 5, 2026. The owner reports the failure occurred on December 1, 2025. The report was geocoded to Texas based on the filer's self-reported location. The affected component is categorized as other/i am not sure, 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 CHEVROLET SUBURBAN cohort independently describe similar other/i am not sure 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 2018 CHEVROLET SUBURBAN shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
I am reporting a safety issue involving a Cybex Eternis S child car seat. The seat was manufactured on 02/28/2020 and has a printed expiration date of 02/25/2030, indicating a 10 year usable life. At approximately five years of use, the head impact foam failed and is broken into two separate pieces. The foam pieces are detached. This foam is a required safety component. Cybex customer service confirmed in writing that if the head impact foam is detached or broken into separate pieces, the seat does not meet safety requirements and should not be used. Cybex also confirmed that no replacement part is available and no repair or remedy is offered. As a result, the seat is unsafe and unusable halfway through its stated usable life, with no ability to repair or replace the failed safety component. This raises concerns about product safety support for child restraint systems marketed with extended usable lifespans.
