2015 Tacoma roll sensor ISSUE

I have a 2015 Tacoma and had a leveling kit and 32" tires installed. when I make a sharp turn (either direction, any speed) the front opposite brake is automatically applied. This pulls me nearly off the road or almost into on-coming traffic.

A little back history...I had a cabover camper on my truck for the last year and originally had the airbags installed for the support. the leveling kit popped one of the air bags. so I switched and added a leaf spring. I never had the issue with the camper on (taking turns slower being so top heavy). I also had the leveling kit installed with the camper on.

4 months ago I took the cabover off. Driving around with the ass end a little high because I left the add-a-leaf on (the camper will be taken on and off as needed) and first had the issue driving around Lake Tahoe (pretty windy, paved road, dry) it happened 3 times that day. I took it to the dealership right away. first they plugged the truck in to see the codes, which showed all three times I mentioned - one tire spinning faster than the other I believe he said. inspected the leveling kit, installed correctly they said and went for a test drive and found no issues. he said I must have slid out on dirt and my ABS went off. I assured I hadn't. over the next few months this happens several times when in the mountains. it doesn't happen every day, just on very windy roads. I took it back to where I had the leveling kit installed and they couldn't find any issues either, they also brought it to Toyota to talk with someone. they test drove over and over and couldn't get it to replicate the issue. I finally drove the service manager around on a windy road and the issue occurred. He said for some reason the Y sensor was applying the opposite brake because it thinks I'm rolling. they gave me a rental truck while they inspected the truck. a week later they said I needed to remove the lift and over sized tires for them to continue to diagnose the problem. they apparently adjusted the Y sensor hoping that would resolve but it didn't. so I removed the add-a-leaf hoping that would solve the problem. it didn't.

Hoping someone might have some advise on what to do next.

thank you!
