NHTSA Complaint #11423031 — 2020 HONDA CR-V

There is a wiring harness for automatic mirror dimming that runs out of the front headliner to the back of the rear-view mirror (P/N32155-TLA-A31 32119) that seems to be without sufficient strain relief inside the mirror. On 5/9/2021, I started my CR-V only to have multiple system failure warnings scrolling across the dash. On 5/10/2021, I took the vehicle to the dealership. They found a blown fuse (P/N 38221-SNA-A41) but were not able to determine why it blew. On 5/25/2021, the same problem reoccurred. I took the vehicle that day to the dealership. The only difference was that (at least as I knew at the time) was that both failures happened after I used the remote start function. On 5/26/2021, after many attempts to duplicate the problem using remote start, the dealership contacted me saying they needed to do more troubleshooting. On 5/27/2021, The dealership contacted me saying they had determined the problem was a short in the above-mentioned harness and asked if I had hung anything on it. I mentioned that I occasionally hung my Handicap Placard (net weight 0.7 ounces) on it, but it would also be bumped by the windshield sunshade I use. The service advisor said that the repairs were not covered under the warranty since it was something I did, and not the fault of the vehicle. I asked the dealership to provide me with the damaged harness for my inspection, and the service advisor agreed to that. When the vehicle was returned to me on 6/4/2021, the harness was not in the vehicle, nor, according to the service advisor, in the building. I am an engineer with years of experience in cabling and harnesses, I wanted to see the damage for myself, as well as what physical harness strain relief accommodations were made for it. When the second incident happened, we were near home, and the dealership. It could have happened a week later when we were on our vacation and driving through the middle of the wheat fields of Kansas - stranded.
