Still have not been able to take mine in yet so if you would be so kind as to report back with what they find that would be great.Hi there, I saw your post and I recently purchased a 2021 TB with 300 miles back in August. I now have 5K and last week it started doing the same thing as you explained.No forward collision, lane keep, adaptive cruise, the buttons don't even do anything when I press them. All was working great, and just stopped. I have checked for updates and there is none. I have removed my toll tag that was under my rearview mirror thinking that was the issue. Still, no fix, and the dealership I spoke with told me to drop it off but couldn't give me a time frame and they told me they had no rentals available and this is my only vehicle, hoping someone has found a fix.....or do I just need to take it in and rent a car? Hate that I am paying for a car with all these excellent features that don't work.
