My 2017 Prius is having headlight failure. I was told by my neighbor that my headlight was out. I bought a new one and went to replace it but they were both working. Thought it was a defective bulb so waited to replace it. I check both headlights when I come to a stop behind a car so I can check the reflection of the headlights. Sometimes they are both on sometimes only one is on, Occasionally both are OUT. What I have noticed is when I turn on the car, immediately the headlights are bright,(not high beam) and immediately go dim. This acts like a bad contact or high resistance somewhere in the circuit. The headlights going on and off seems to be a circuit breaker of some kind. Fortunately I don't drive much at night, however I am having to drive more at night and the possibly of the headlights both failing is TERRIFYING. …
Headlights intermittently go off, and I wound have to switch it off and on for light to come back on, but for few minutes until it does it again, and I drive Uber at night. I have searched the problem online, it seems to be a common problem on the second generation Prius from 04-09, I called few repair shops and they acknowledged the problem but did not have an answer to solve it.
Speed control & acceleration all 71 →
I went to park in a parallel space when all of a sudden my ABS, (!), VSC light come on with the loss of brake power and a loud beeping noise. With this sudden loss of brakes in the middle of driving, I could have harmed myself and others in any cars around me because I also lost steering capability. This is a problem that there was an extended warranty for, but there should be a recall. My car is a 2009 and was only covered before the pandemic and now it is 2021 and I have no recourse, but to try and fork over $3500.00 for which I don't have. I am a second owner and this is a very common problem amongst Prius owners. I didn't have any other symptoms that I could point out prior to this situation. I have had my hybrid battery, engine, ecu and most recently a stolen catalytic converter replaced. This ABS actuator problem needs to be addressed for another 5 years with a free repair. …
When I am coming to a stop or need to put on my brakes my car will accelerate at a jump ahead pace As if to take off instead of slowing down and stopping. Regardless whether I'm turning a corner or I'm continuing straight when I have to Put on the brakes it speeds up instead.
