I called customer service to find out what is going on. The customer service rep said he couldn't find out. He doesn't have a way to track it that is different from what I have on the web. He said to contact the dealership. Ive been in steady contact with the dealer and he does have any idea...
I ordered the tow package as well but I was unware it had a trailer brake. It doesn't seem like trailer sway control is the same thing.
Now, Trail brake is a thing and I could definitely see where that would cause a fault if you were on the highway with it. I went back a nd looked at the photo...
