Toyota's was eager to investigate issues with the GR Supra during my year of ownership and following the problems with that car - including excessive oil consumption. The motor in the Supra was modified from MY2020 to MY2021+ and in the 2021 cars, a few of them exhibited oil consumption out of spec according to both Toyota and BMW - which often led to flying some expert out to dealers to inspect motors, perform tests, etc. Outcomes of whether or not people got their engines rebuilt or replaced were mixed but the key is Toyota was very interested in studying the problem.
Related to the original post in this thread which showed a dipstick with crud on it...my brain just made the connection that my dipstick had stubborn bits stuck to it around ~2,500 miles. They were not present on my dipstick early on (I have photos because my car was delivered lower on oil), but I stupidly didn't think more of it and vigorously rubbed it off without documenting it. However, I did a crappy job of cleaning (or there's new build-up) because I pulled my dipstick today and see there's still (gray) stuff on it near the edge around the low oil marker. Sorry the phone photo doesn't look great.
Someone else I know with a new GR86 shared with me that his dipstick has similar crud on it and he's still in his break-in period of <1,000 miles. Not sure what to make of it yet, but the dipstick should not have this foreign material on it.
