NHTSA Complaint about ELECTRICAL SYSTEM: INTEGRATED TRAILER BRAKE CONTROL filed November 25, 2023

NHTSA complaint #1945408 (ODI reference 11556746) concerns a 2024 CHEVROLET SILVERADO 3500 and was filed on November 25, 2023. The owner reports the failure occurred on September 28, 2023. The report was geocoded to Tennessee based on the filer's self-reported location. The affected component is categorized as electrical system: integrated trailer brake control, 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 SILVERADO 3500 cohort independently describe similar electrical system: integrated trailer brake control 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 CHEVROLET SILVERADO 3500 shows the complete component-level complaint distribution alongside any active investigations or recalls.

Complaint Description

I have issues where I am connected to a new 42" 5th wheel and constantly get "Check Trailer Wiring" warnings as we drive down the road. I have been running with the lights on and they are on and fine, when the warning displays, but lose brakes to the trailer (both through pressing the brakes or controller and the trailer indicator light goes off). I cleaned the ground area and replaced the connector and still see issues. I checked continuity in the cable and good. I have been adding dielectric grease to the 7-pin connector. I saw a YouTube video where another gentleman, with a similar vehicle, had had the same issue and got a recall under GM Service Bulletin 6379278 for a trailer brake controller replacement. When I talked to GM/Chevy Consumer support, they advised that my truck was not under this bulletin and advised to call the NHTSA to get a case open or added to the service bulletin. I have a case open with GM #9-11303425686.
