What causes my Ford Focus to shake when I accelerate?

I recently purchased a used Ford Focus and have noticed that whenever I accelerate, the car starts to shake. This only seems to happen when I reach around 40-50 mph. What could be causing this and how can I fix it?

This could be a sign of a few different issues. One possibility could be that your tires are unbalanced or need to be replaced. Another potential cause could be faulty spark plugs or ignition coils. I recommend taking your car to a mechanic to get it checked out.

I had the same issue with my Ford Focus and it turned out to be a problem with the transmission. I suggest bringing it to a dealership to have it looked at as soon as possible.
