Just got my 2017 Acadia and in the process of getting it ready to flat tow. I'll share a few of the issues I had so far. Must be the 3.6 engine, cigarette lighter power outlet in front is only part time, so need to run a outlet direct to battery if you use a supplemental braking system( I have the RVi2) for it.
Not hard to do I used the hood release hole in firewall to run cigarette lighter cable and breakaway cord and installed a rubber grommet around all three, tight fit but got it done.
I was going to install bulbs in the rear taillights for brake and turn signal but found out their is no room to drill hole in reflector to do so. Then decided to wire the toad lights to the RV, sounds easy in the Etrailer video but found out also need to hook a relay to my brake switch under the dash.
I did not feel like ripping my dash apart. So I went with some magnetic stick on lights in the back, not my first choice but seems the safe way to do it.
I popped the boot off the shifter and just decided to leave it loose in the back part. you don't need a screwdriver to release the shifter you can reach in with your finger and hold the white plastic piece up to free it. If you do use a supplemental braking system you need to get the kit to keep the unit from sliding back too far. The Acadia uses a gentle slope for the front seat so when the braking system is used it slides up.
Other than needing a 4 inch drop receiver hitch adapter I think that all I have done so far.
