I have not had this happen with either of my trailers - one is 7 pin the other flat 4 pin. Blind spot monitors pick up cars as they normally do with both trailers.

Do you have a ref for where you saw this?So using the round trailer plug changes the sensor setup and also supposedly activates “tow mode”.
I have surge brakes on my trailer, so I don't think this is how it's detecting you towing something.Might try that but I would think it may be detecting the brake system rather than lighting. Otherwise these changes would occur using the flat plug.
I read it somewhere on this forum but can't confirm if it is true or not. Probably “fake” news......Do you have a ref for where you saw this?
