    Other brakes problem

    "received online alert to "Pull over immediately or car will be on fire". But according to Toyota this is not true and quoted $7000 replacement and 4 weeks to get batteries and that we could drive it the 100 miles to service. Got local Hybrid Guy to replace with Toyota Panasonic new batteries for $1675 and his work was guaranteed. Forget going to Toyota."

    Anonymous, (2012 Toyota Prius C Unsure 1.5-L 4 Cyl hybrid)

    Engine Major

    Engine rebuild or replacement, cylinder head, head gasket, turbocharger or supercharger, timing chain or belt.

    What Owners Say

    Head gasket

    "I had had an oil change at the dealership. I was driving home and it sounded like somebody had actually left a wrench or some other tool under the hood. I came back and they found nothing but the sound had stopped. The next day or two when I would start the car, it would do very, very loud rattling. Engine light would come on. So I took it in again to the dealership and they informed me that there was a crack in one of the gaskets the head gasket. It cost around $4000 to fix the problem. I would also like to note though this may sound odd since the Prius is known as a progressive car, I dont think I would ever have a progressive car again in a very conservative state, such as Oklahoma. Even the dealerships here do not seem to be competent and dealing with Prius issues. I have had to contact Prius dealers in other places, such as California to get correct information."
