## Narrative
In January 2024, I parked my truck in my garage and shortly after I smelled an electrical burning smell in our house. When I opened the garage, it had smoke throughout the garage and a very strong odor of electrical burning smell. I moved my vehicle outside and tried to find the source, but it was too strong to narrow it down, and the garage smelled like burnt electrical for days. I took the truck to a service shop and they could not find anything wrong at the time. Today, May 2024, I was having trouble getting my trailer lights working. Upon further inspection, I discovered the 7-way interface wiring harness on my vehicle had electrically shorted out and melted a hole in the plastic housing and left melted plastic on the truck frame. The tag on the wiring harness states TAG #138359 7-WAY INTERFACE HARNESS W/O 134971. I believe this electrical short/fire should be part of the NHSTA Recall 18E-014. That recall states those are aftermarket harnesses, but the harness on the vehicle in this complaint is original to the vehicle and was installed by the manufacturer. I plan to take the vehicle back to the dealer to have the harness replaced, but I am expecting pushback since the NHSTA recall states this is only aftermarket harnesses.
