Hi -- it's been a very long time since I've been here. I had a 2007 Prius and then several others before buying my Prius in 3015. My mileage is terrible -- 39.9mpg. I've gotten just over 40 mpg only five or so times since I bought the car new in 2015. I've taken it to two different dealers and called Toyota. I've been told the problem was the way I drive (never had this problem with my 2007 Prius), the kind of gas I'm using (They told me only to buy name-brand gas, didn't help), that it wasn't broken in (It has around 20,000 miles), etc. Basically, no one has been able to give me an answer that makes any sense. Today, the Toyota mechanic told be that my mileage was pretty normal. I might have slugged him if I hadn't been so busy thanking my lucky stars toe alive. Which brings me to the real issue I signed in tonight....... I was driving today to another town -- I was about 15 miles from home -- when the red BRAKE light and the yellow ABS lights came on. The brakes suddenly felt a bit weird, but I frankly wasn't sure that it wasn't my imagination. I pulled into a parking lot and I checked the manual, and then I called the service department at the Toyota dealership. They told me something was going on with the brakes and to bring it in. I was 15 miles out of town in rural Indiana, as so I was concerned. I asked if the car was safe to drive, and he said it should be fine -- I just didn't have anti-lock brakes. So I headed back. After about 10 miles, I no longer had any doubt that my brakes were not functioning properly. Once I got back into town, they got steadily worse. By the time I got to the light to turn into the dealership, the only way I could keep my car from rolling was to put both feet on the brakes and exert as much pressure as I possibly could. I've never been so happy and relieved to get out of my car! When I spoke to the mechanic, I told him I had no brakes. Clearly I was shaken, but by no means hysterical. He was very dismissive and said he was sure it wasn't too bad. After half an hour, he approached me in the waiting room. He said, "You have a SERIOUS problem -- you have NO brakes!" (Well, duh!). He said he problem was the brake caliper and that I didn't have a drop of brake fluid. They'd have to order a part, but it will be ready tomorrow. So here's my question, or rather, questions: Is this normal for something to happen to this part in a car that's only two years old? Would this be likely to something that happened suddenly, or was this a gradual thing that just reached the tipping point today? Might there be any secondary damage from driving the car 15 miles after the light came on? Are there any follow-up questions I should ask before I sign for the car tomorrow? I appreciate any advice anyone can offer.
