Before purchasing a 2016 camaro last year I took it to a Chevrolet dealership for a safety inspection with no safety concerns found and after purchasing it around 57,000 miles went to another Chevrolet dealership to diagnose any electrical concerns occurring with the car that I noticed. There was nothing found but I still noticed humming sound and let them know and they found no concerns whatsoever. The battery was replaced twice as over the course of the year the electricals decreased in power. I then notified my insurance there was an issue with the car drawing power and it would not start. Upon checking the trunk noticed water had gotten into and possibly damaged the trunk/rear fuse block. I went through my insurance to fix any body damage but no electricals were fixed based on the insurance representative declining to accept liability for the damage and upon return of my vehicle, the repair facility started the car against my wishes and the rear fuse block in the trunk sparked and caused a fire to start in the trunk that continued for about a minute or two. Upon taking it to Chevrolet this year again after this, I was charged $800 for them to not diagnose anything but to say the x-connectors were burned up in the incident as well (I said this previously as this started the fire as it carries the currents from the fuse block) and to say they cannot find the source of the water leak/entry or replace the fuse block as the x-connectors and harness for the car, the first parts needed to be repaired to establish power to the car, have been discontinued. For more details on the cause, effects, and repair steps necessary but not been able to completed by GM/Chevrolet please refer to this service bulletin that I noticed was raised after I purchased this car upon researching the issue MULTIPLE chevrolet dealerships, ignored, didn't notice, and now are saying cannot repair and should be followed up on: 18-NA-375. Car is at ~70,000 miles currently.
