I think those have all been overcome, especially since the Marines are using it to transport the President. Remember that the initial M-1 Abrams prototypes and test production had a great number of problems as it was being developed, but it has proved fairly reliable for the last 30 years.
When the M1 malfunctions it doesn't crash into the ground. It just becomes a 52 ton armed and armored foxhole.
So were Blackhawks with stabilator issues back in 81. I still don’t trust Ospreys, though.
