2021 CHEVROLET TRAVERSE — Complaint #2002465
Open-data reference.
NHTSA Complaint about ENGINE AND ENGINE COOLING:EXHAUST SYSTEM filed June 25, 2024
NHTSA complaint #2002465 (ODI reference 11596535) concerns a 2021 CHEVROLET TRAVERSE and was filed on June 25, 2024. The owner reports the failure occurred on April 22, 2024. The vehicle had 33,000 miles on the odometer at the time of the incident. The report was geocoded to Massachusetts based on the filer's self-reported location. The affected component is categorized as engine and engine cooling:exhaust system, 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. No VIN was supplied by the filer, so this complaint contributes to model-year trend data but cannot be tied to a specific vehicle.
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 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 2021 CHEVROLET TRAVERSE shows the complete component-level complaint distribution alongside any active investigations or recalls.
