No_Pain, having trouble reading your attachments. I have a 2018 SR5 with the 6cyl. Purchased the end of 2018. It has about 600 miles on it. I noticed the idle surge when "carefully" entering garage. Like other say, it can be a surprise. What all did the dealership do, and did it correct...
I purchased a new 2018 end of year. Before I could pick up, they had to complete a recall that was to replace master cylinder. I thought it was for potential leaks, but sounds like you should have it replaced regardless.
