The automatic trailer blind spot detection on my 2020 Limited is hit or miss. Sometimes when I hitch up, pull out and corner it comes on, most other times it never comes on the entire trip. Is there a way to force trailer blind spot detection on?
I've mostly had mine detect the trailer reliably. One time it didn't detect anything. A couple times it said either "auto" or "20ft". I'd say half the time or more it correctly registers 30ft.
Yes, I'm using the 7 pin. I have a utility trailer with no brakes 4-pin that it has detected also one time for blind spot. It's frustrating me why hit sometimes detects and sometimes it does not
I have the same problem 2021 Ream 1500 Crew Cab. I have one enclosed trailer 20 v nose 16' flat side that it does not work so every time I turn on my turn signal I am irritated, I have pulled into a parking lot and did figure 8's and 90 deg. turns and backup turns as well. I have other trailers that it works fine.
So far I've only used the 4 pin connector and it has reliably detected my trailer each time, but normally does not detect it until I make the first turn. I've never seen a way to force it.
