Hello! I got my 2013 Prius a few weeks ago. It has 80,000 miles on it. I was going about 30 mph when it suddenly felt like my brakes had engaged automatically, accompanied by a scraping noise. The traction control light also came on. The noise and feeling were like a tire had blown or kind of like driving with the emergency brake on. I pulled over and didn’t see anything wrong with my tires. So I got back on the road and it happened again at around 25mph. I turned off the car and started it up again and it drove smoothly the rest of the way home. Any idea what this might be?
