Owner Complaints (2)
Your Prius has a leak in the exhaust heat-exchanger coolant pipe, which is part of the hybrid cooling system. When this pipe fails, coolant can drain completely, causing your engine to overheat suddenly and potentially lose power or shut down while you're driving — creating a serious safety risk, especially with children in the car. Your dealer confirmed the leak and says the vehicle isn't safe to drive until the pipe is replaced, which costs about $2,249 and requires ordering a part that's currently backordered. The fix involves replacing the front exhaust cooling pipe with a new one once it becomes available.

I BOUGHT A BRAND NEW 2019 PRIUS FROM THE DEALERSHIP THAT I WORK AT. ONLY A MONTH LATER, THE PRE COLLISION SYSTEM STARTED BECOME UNAVAILABLE AND THE ENGINE STARTED MAKING A LOUD CRANKING NOISE. I TOOK IT TO TOYOTA AND THEY TOLD ME THAT THE PCS MILIMETRE WAVE SENSOR WAS MISSING FROM THE CAR. THEY ALSO DID NOT WANT TO FIX THE ENGINE PROBLEM OR EVEN LOOK INTO IT DESPITE STILL HAVING WARRANTY LEFT.
