NHTSA Complaint #11580697 — 2019 MERCEDES-BENZ CLS 450

My car started shaking and after putting it on the computer it was an electrical wiring harness issue. I was told it will be 6 k to replace both harnesses. It’s been 8 months and they just received the part. The service tech told me that these cars have this issue due to the position of the harnesses being to close to the exhaust. It dries out the wiring. I went to the Mercedes forum and found numerous complaints about this issue. Recently I baited the Mercedes of downtown Los Angeles and was advised they received another cls 450 with the same issues as myself and several other owners of the cls 450. I have been getting the run around for months. This should be a recall as even if I pay 6k it will happen again! Please help. I even reached out to BBB and the dealership never responded to them. I’ve been in contact with Mercedes head quarters and was advised to reach out to NHTSA
