Driving down the road at normal speed, I noticed the car overheating. This had never happened. Pulling into a 70 year old service center in cranston, rhode island, I left the car with reliable service people and they checked it out. It seems that the bolts had come loose from the engine and fluid was going into the pistons,they reported to me that the threads in the engine were faulty, I think they said alumium, and they should have been metal. I am not mechically inclined so I dont understand the whole problem. They said that the engine head was not secure and this has happened to other Toyota engines. Anyway, at 70 yrs old, it took all the money I had to repair it and they insisted that I look for a recall, because that should have never happened. $1842. 00 later, the car is running like it should now. If Toyota doesnt take care of me, I will spend the rest of my life spreading the word. I will start at the rhode island dealers, go on line and contact all the proper areas. This should not have happened to my Toyota. This is the car that they advertise will last 265000 miles if maintained properly. I bought the car at earl stewart Toyota in lake park, florida. Mr stewart told me he was sorry that this happened, to report it to Toyota. My wife passed away and it moved back to my home state in rhode island. The car was maintained by Toyota always thru my warrenty.
