    I have a used 2012 Prius for 2 years. This is the first time I have had problems with it.
    Minor engine shaking presented occasionally at first.
    More pronounced after an oil change with coolant loss and white smoke from exhaust after I add more coolant to resovoir. The smaller one has no issues. I used the red zerex coolant by valvoline. I do not know what firestone used in the oil change, just that they would use 0-20 oil.

    @AkaiSJ 's sleeping in? This one's pretty much a slam-dunk head gasket failure, anyway.
