What fault do the new Boeing aircrafts suffer from?

It seems that nowadays nothing is made as sturdy as it once was. People do not put a lot of effort into making and building things correctly. The builders just seem to want to get the job done even if it is with low quality materials and without putting a lot of effort into it. Not all aircrafts from Boeing are having problems. Today, it is the Boeing 737 Max 8 aircrafts that have been grounded and are causing problems.

One thing that has been found to be a problem on these aircrafts have been the airplane nosediving. The software was meant to stop the plane from stalling, but it actually causes the plane to nosedive instead. Another problem is the pilots need to be able to override things.
