2021 GMC ACADIA — Complaint #2178397
Open-data reference.
NHTSA Complaint about FUEL SYSTEM, GASOLINE filed February 19, 2026
NHTSA complaint #2178397 (ODI reference 11719020) concerns a 2021 GMC ACADIA and was filed on February 19, 2026. The owner reports the failure occurred on February 13, 2026. The vehicle had 46,000 miles on the odometer at the time of the incident. The report was geocoded to Tennessee based on the filer's self-reported location. The affected component is categorized as fuel system, gasoline, 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 ACADIA cohort independently describe similar fuel system, gasoline 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 GMC ACADIA shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2021 GMC Acadia. The contact stated that while driving approximately 30 MPH, the vehicle started running rough before the vehicle stalled. The contact attempted to restart the vehicle, but the vehicle failed to restart. There was no warning illuminated. The vehicle was towed to a local dealer, where it was diagnosed and determined that the fuel pump module had failed and needed to be replaced. The dealer informed the contact that the part to do the repair was on backorder. The contact researched online and associated the failure with NHTSA Campaign Number: 20V639000 (Fuel System, Gasoline); however, the model year and VIN were not included in the recall.
