2019 GMC SIERRA 1500 — Complaint #2159635
Open-data reference.
NHTSA Complaint about POWER TRAIN:AUTOMATIC TRANSMISSION:TORQUE CONVERTER filed December 22, 2025
NHTSA complaint #2159635 (ODI reference 11706562) concerns a 2019 GMC SIERRA 1500 and was filed on December 22, 2025. The owner reports the failure occurred on May 22, 2020. The vehicle had 57,000 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 power train:automatic transmission:torque converter, 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 power train:automatic transmission:torque converter 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 that in the first month that the vehicle was purchased, the vehicle intermittently hesitated before slamming into gear hard. No warning lights were illuminated. The vehicle was taken to the dealer, and the contact was informed that the manufacturer was aware of the failure and suggested that a triple fluid flush was needed, and the triple fluid flush was performed. The contact stated that the hard shifting persisted, especially while driving uphill. The vehicle was taken back to the dealer, where it was diagnosed and determined that the torque converter had failed and needed to be replaced. The vehicle was not repaired. The failure persisted, and the vehicle remained at the contact's parents' residence unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 57,000.
