Exact same problem on my 2017 Ford Edge Titanium. Both harnesses shredded. This is not a 'wear and tear' issue that happens from regular driving, it's is faulty design & assembly issue. This should be a recall by Ford. My mechanic showed me the harnesses after and they are completely torn to bits. Absolutely ridiculous, no way should that happen if these harnesses are routed properly. Just another poor design issue by Ford, so many problems on this car it's ridiculous. Total lemon. Never buying a Ford again.
