Check your CV joints - usually you'll hear them clicking the most when you turn a corner while pressing on the gas, but they can make noise like that while you're driving straight. Given that it's most prominent above 35mph, I'm not sure that this is going to be the issue, but it's worth checking - if it is a CV joint, and it breaks, your car will coast to a stop and you won't be going anywhere except on the back of a flatbed.

Since you did not mention that there are any warning lights on at the dash, I must advise you of the following: Prius vehicles are VERY PICKY when it comes to the proper weight of oil. That being said, and if you have the wrong weight oil in it, expect problems. Easy way to check this: Take off the tube going to the throttle body at the front of the engine. Open the throttle plate & look down into the intake...Do you see any oil laying there, in puddles? If so, you def have incorrect oil in the engine. This will NOT det a DTC code, and it WILL give you your condition.
