大部分人都遇到过这样的问题 怎么说

对中国人来说都是问题,但在外语里面,你说的问题分两种,技术上的问题是question,troubleshooting,
生活上的问题是trouble,problem.

因此,这个你根据适当选一个.换一下就可以.

【译:The kind of problem is common to most of people.】
我想这样说好些. 因经常说 it is common 来安慰人.
要一对一来译,也行,
【Most of people ever faced this kind of problem.】

另:people是的统称,是不可数名词,因此好象不用most people.好象都是most of people.

That happens.
That's often the case.
这是常有的事。( 地道的口语表达）

Most people will meet such a problem

This is a problem that most of people have faced.

most of people have suffered such a problem

The majority of people meet the problem like this.
