2024 GMC SIERRA 1500 — Complaint #2135225
Open-data reference.
NHTSA Complaint about POWER TRAIN:DRIVELINE:DIFFERENTIAL UNIT filed September 30, 2025
NHTSA complaint #2135225 (ODI reference 11690577) concerns a 2024 GMC SIERRA 1500 and was filed on September 30, 2025. The owner reports the failure occurred on July 14, 2025. The vehicle had 48,000 miles on the odometer at the time of the incident. The report was geocoded to Arizona based on the filer's self-reported location. The affected component is categorized as power train:driveline:differential unit, 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:driveline:differential unit 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 2024 GMC SIERRA 1500 shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2024 GMC Sierra 1500. The contact stated that while driving approximately 65 MPH, the vehicle rolled over a bump in the highway, and the message to "Slow Down" was displayed on the instrument cluster. The contact heard an abnormal metal-on-metal sound coming from the vehicle. The contact had taken the vehicle to a local dealer who diagnosed the vehicle and determined that the supports for the differential and the rear axles had been improperly attached and had become loose. The contact had asked the dealer if the repair could be covered under warranty, and was advised that the repairs were not covered. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 48,000.
