Hi, I could'nt find an existing thread that answers to my question. I have a 2025 Turbo and had the dealer install the OEM hitch and 7 pin connector. I've been pulling a small trailer and the Trailer Mode turns on, so all good on that point. My question is that I will be purchasing a 2400LBS rv trailer that has electric brakes. The part advisor at my dealer (who had to talk to 5 other people at the dealership...) came back and told me I don't have to add an external brake controller...So, if I interpret my dealers answer, this would mean that the brake controller is integrated into the Trailer Mode or something of that sort...Does this even make sense? I also spoke to a trailer dealer and he tells me there are no connectors for brake controllers on CX50...So I'm even more dizzy about all that. Anyone went through this headache ?

There's a type of trailer brake called a 'surge' brake. It involves a master cylinder integrated into the trailer tow tongue. When the vehicle brakes, the trailer's momentum presses the master cylinder, which then applies pressure to the slave cylinders in the wheel hubs of the trailer. They need to be properly maintained (ie: the sliding tongue needs to be lubricated), but they require no modification to the tow vehicle. Perhaps that's what they're implying should be used?
Notice that the smallest one is for 7500lbs?
I think, if you drive carefully, load your trailer correctly to avoid sway, and watch your speed, you can pull 3500lbs without brakes. I know I've pulled at least 2000lbs without feeling like the vehicle brakes couldn't handle it.

The 6sp in the Turbo CX-30 and CX-50T is a heavier duty transmission than the NA. Possibly the CX-5 Turbo as well. It should be able to handle the extra loading.
I just got back from a 300mile round trip in 100deg weather, towing at least 2500lbs and had no overheating or brake concerns.

This was the trailer I towed at at least 10mph over the limit (max of 75mph) and there is no deficiency in the braking for towing. I do use the transmission to help slow things down when I'm planning ahead, but I have no concerns with not having enough braking for a panic stop. Of course that's going to add a lot of heat very quickly, but you should be able to do it once without overheating to the point of brake fade.
Can confirm 12mpg or 20L/100km for the whole trip, whether I kept it at 60mph or 75mph.
