Car was working fine all day and then something started making a noise under the car and it would not move anymore when I accelerated, I can put the car into the gear in the car the car itself just will not move and when I accelerate it just feels like something has been broken.

I do not have service information for your model, but I suspect it is a front-wheel-drive car. Look underneath when a helper shifts into gear and releases the clutch. Watch the two half shafts. One on each side goes to each front wheel. If you see the inner-most part of one shaft spinning right next to the transmission, that inner CV joint is broken. If the entire shaft is spinning, all the way up to the wheel, the outer CV joint is broken. Usually the spinning shaft will flop around and make noise, but not always.

It is much more common for an outer joint to break, and that most commonly occurs when the steering system is turned fully one direction. There are six giant steel marbles in there. They will make a clicking sound intermittently for a long time before those marbles fall out. You will also see the accordion-shaped rubber boot around the joint is all twisted up or is torn in half.

If I am right, the fix for that is a rebuilt half shaft. The cost has come down a lot on them. Some cost less than $100.00. On most cars they take less than an hour to replace.
