I was driving suddenly I started to lose power within few second the car stalled and got an hybrid error and the car went in safe mode the car doesn't go in d only n or p, also the dashboard lighting goes on and off and smoking so I towed the car to larry h miller Toyota corona CA, the manage dustin said this is recall issue and we need to update the software two days later the service agent mrs lorena said we found coolant in the oil and our service tech thinks I have blown head gasket but talking with Toyota manufacturer is covered and I can get rental car too but I need to authorise $2040 year down because Toyota wants to know what cause the head gasket to failed but mrs lorena assured me �I 100% covered and I will not have to pay� so I agreed two days later dustin the service manager called and said I need to come to dealer shop he wants to show me something so I had to call the base (air force) and get half day off when I got there my car was disassembled except I could see the pistons and the block Toyota tech had rulers and fillers gage and showing me that my block is warped about 0. 008 inch and I need a new engine around $11,000 or used about $8,200 or I can take my car as is without paying anything I told I cannot affords it so I towed the car home, prior to becoming an engineer I was machinest so I sent the head to machine shop for examination the cylinder head was flat and has no crack or sign of failure and made of aluminium if the block is warped the head should be warped too and the tech measurements was incorrect because after cleaning the block surface from gasket debris was flat too so I called the dealer about my finding I was told dustin is in vacation and coming back on 2/12/2019 today is 2/14/2019 and he is not returning my call I took the car running but doesn't go to drive for recall now I have disassembled car.

4 Engine Head Gasket Failure problem of the 2010 Toyota Prius

Failure Date: 09/01/2015

My car is consuming about 1 quart of oil every thousand miles, sometimes even more. I have always got the oil replaced in a very timely manner and with only around 118,000 miles on it, this is very troubling. My dealership is aware of this problem and they have charged me upwards of $4,000 to replace the head gasket and the oil pan gasket saying it would solve the problem, which it didn't. They did the oil compression check with no sign of where the oil was going as there were no additional leaks according to them. They refuse to think this is a problem, which I think is a blatant lie. They know that this shouldn't be the case and want me to get the engine rebuilt for an additional $4,500, which is ridiculous for a car with such low mileage. I want Toyota to fix this problem now. I am very concerned about my safety as I have to constantly keep adding oil, which is wrong!.
