    I have a 2020 prius prime plug in with 52,000 miles. When driving on gas up hill between 15-30 mph there is a rattrling engine noise that appears intermittently. Takes a while to hear the nouse but only happens going up hill on gas. Toyota mechanic could not detect the problem. Does not occur on speeds above 35mph.
