I have a 2013 prius (regular, not plug in, "c" or "v") with about 275k miles on it. I've been having engine problems for about a year & a half which is when the overheating warning light started flashing. At that time I replaced the water pump only to find out coolant was leaking so I put " stop leak" in it which seemed to help temporarily but shortly after started overheating again. I had the engine replaced, but the check engine light was still on & it would flash the overheating light when going up hills. Recently I've taken it to toyota where they said something involving the AC compressor was causing the engine to overheat so they fixed it but it was still overheating. A few days ago it broke down after an hour on the interstate with a "check hybrid system stop vehicle in a safe place" warning & was popping a P0117 "Engine coolant temperature sensor 1 circuit low" so after letting it cool down I added more coolant. She would barely accelerate after I started her & i had to get a tow because she wouldn't go more than 20 yards before dying. After being towed she wouldn't start at all. I'm bringing it to toyota Wed again any suggestions on how i can get it started or fix the problem?
