Open-data reference.
NHTSA Complaint about ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE filed April 18, 2025
NHTSA complaint #2084140 (ODI reference 11655469) concerns a 2019 GMC SIERRA 1500 and was filed on April 18, 2025. The owner reports the failure occurred on April 17, 2025. The vehicle had 107,105 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 engine and engine cooling:exhaust system:manifold/header/muffler/tail pipe, 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 GMC SIERRA 1500 cohort independently describe similar engine and engine cooling:exhaust system:manifold/header/muffler/tail pipe 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 2019 GMC SIERRA 1500 shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2019 GMC Sierra 1500. The contact stated while the vehicle was parked, the driver's side tail pipe flange bolts connecting the tail pipe and the muffler snapped, causing the tail pipe to hang down. There were no warning lights illuminated. The contact had gone underneath the vehicle and saw that the muffler was disconnected from the tail pipe and that the exhaust bolts had snapped. The dealer was contacted, and an appointment was scheduled to have the vehicle repaired; however, the vehicle was not yet repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 107,105.
