2018 M3 gas tank has cracked on the top and gas slushes around and leaks out. I filled up my tank and gas started leaking from the bottom. 2015-2016 BMW covers it but mine is made in 2017 has the same issue but no recall. This is very dangerous because it’s gas related.
Forgot to include on initial complaint that cracked gas tank was identified by dealer. There was a previous NHTSA recall for the same platform, but did not include the 2018 model year.
After filling gas tank a strong aroma of gasoline was noticeable. This happened three successive times.
