I was really over this car today. While trying to get home, less than 3 miles away, the chime went off once, and the CHECK HYBRID SYSTEM warning came on. The car slowed to a crawl, then nothing. i managed to get over out of rush hour traffic and get Green Tech Auto on the phone, less than a mile away. i didn't get an answer at the shop, so I started it again, and nursed it there, almost made it to the door. The tech came out and tested it. After about 15 minutes of codes, what showed up was a bad water pump. What he told me was that the engine shuts down when this happens to keep the engine from overheating. He stored it for the night, gave me a ride home, and will call his "non-hybrid drive" mechanic tomorrow. Now i get to spend more money on it. I haven't had a chance to recover from the last big expense, last week. I guess I have to look at it as I don't have a car payment, at least.
I don’t believe your last diagnosis was correct. Bad water pump is really bad news, once you repair that, head gasket is right around the corner
