2020 CHEVROLET TRAVERSE — Complaint #2103359
Open-data reference.
NHTSA Complaint about ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR filed June 24, 2025
NHTSA complaint #2103359 (ODI reference 11668867) concerns a 2020 CHEVROLET TRAVERSE and was filed on June 24, 2025. The owner reports the failure occurred on May 12, 2025. The vehicle had 102,000 miles on the odometer at the time of the incident. The report was geocoded to North Carolina based on the filer's self-reported location. The affected component is categorized as engine and engine cooling:exhaust system:emission control:catalytic convertor, 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 TRAVERSE cohort independently describe similar engine and engine cooling:exhaust system:emission control:catalytic convertor 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 2020 CHEVROLET TRAVERSE shows the complete component-level complaint distribution alongside any active investigations or recalls.
