“The car still needs some work before I will be able to drive it.”

If something “needs work” it means there are tasks that must be completed in order for it to be good quality. It can also mean that a skill or ability needs to be practiced or studied more or harder (such as a school subject).


何かが「needs work」ということは、良いクォリティーにするにはまだやることがあるという意味です。例えば学校の授業などでも使えますが、技術や能力など、もっと練習しないと、もっと勉強をがんばらないといけないということになります。
