2011 Prius, 223,000 miles. Car shakes & rattles (probably rolls too!)when backing up or going forward from a stop. Check engine light is on, sometimes flashes when rattling. Vibration stops at about 20 mph or so. No indication of less mpg or overheating. Help! Tom ---

The flashing CEL and ‘rattleling’ means you have a major problem. It needs to go to a mechanic, preferably towed. ---

If you drive a car with a flashing check-engine light, you can cause expensive damage. ---

Given you car’s hybrid configuration, could be any number of problems. My guess – if OP will allow a guess – is the gasoline engine is misfiring due to unmetered air getting inside, due to a vacuum leak of some sort. That sort of leak will have less effect on performance the greater the engine’s rpm and load.
