2021 CHEVROLET TRAVERSE — Complaint #1931317
Open-data reference.
NHTSA Complaint about ENGINE AND ENGINE COOLING:EXHAUST SYSTEM filed September 27, 2023
NHTSA complaint #1931317 (ODI reference 11546962) concerns a 2021 CHEVROLET TRAVERSE and was filed on September 27, 2023. The owner reports the failure occurred on September 22, 2023. The report was geocoded to Texas 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. 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 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.
Complaint Description
KNOWN ISSUE: Chevy Traverse owners may experience a condition wherein the front exhaust pipe on their crossover separates from the mounting bracket, resulting in damage to the pipe. Now, General Motors has issued new Special Coverage that addresses this issue. NEW ISSUE: Rear exhaust pipe is also affected. When separated/cracked this was leaking carbon monoxide fumes into the inside of the vehicle when driven. Our family's safety was put at risk breathing these fumes. The Chevrolet dealership says that only the front exhaust issue is being recalled/covered but rear is not even when it is attached to same mounting bracket with known issue. Appeared/noticed as loud muffler sound and strong smells of fumes.
