I have a 2021 CX-9 GT. I have an aftermarket tow hitch installed that was put in by the dealer. Ever since I purchased the vehicle, the liftgate will intermittently go up and stop about 6" before reaching the top. It beeps three times when it stops and just stays there. I would say it happens a couple times per week. I thought that maybe it was due to the kayaks I have hanging in my garage above the car or the yakima roof box I had on it all winter. Now, I have just a bike rack installed on the hitch.
Does anyone have an idea what is causing this? I have taken it to the dealership twice and they basically threw their hands up when they could not reproduce it.
Would this be due to a radar sensor detecting something above the tailgate or the tailgate meeting physical resistance and stopping?
Edit: the liftgate never goes up on its own. It's always me pushing the button. The intermittent part is the stopping 6" short and beeping.
