I haven’t been paying attention for some years now.
Did they fix the issues they were having previously?
The ongoing issue is that it tends to run too hot. A design problem from the beginning. Also, turbine blade life cycle is shorter than desired.....that one can be corrected I think.

“The US Air Force Quietly Admits the F-35 is a Failure”
The Air Force has announced a new study into the tactical aviation requirements of future aircraft, dubbed TacAir. In the process of doing so, Air Force chief of staff General Charles Q. Brown finally admitted what’s been obvious for years: The F-35 program has failed to achieve its goals. There is, at this point, little reason to believe it will ever succeed.
According to Brown,(Opens in a new window) the USAF doesn’t just need the NGAD (Next Generation Air Dominance) fighter, a sixth-generation aircraft — it also needs a new, “5th-generation minus / 4.5th-generation aircraft.” Brown acknowledged some recent issues with the F-35 and suggested one potential solution was to fly the plane less often. “I want to moderate how much we’re using those aircraft,” the general said. “You don’t drive your Ferrari to work every day, you only drive it on Sundays. This is our high end, we want to make sure we don’t use it all for the low-end fight... We don’t want to burn up capability now and wish we had it later.”........
