2009 Toyota Prius: headlights failing or too dim

Filed Aug 15, 2021 · Lights · CA

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.

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. I started to research the problem and it seams I am not the only person having the problem. The internet is full of other people having the same problem. It seems that nothing is being done about it. I am hoping that Toyota is NOT deciding to just let the people kill themselves because it will be nearly impossible to prove that the headlights were out at the time of the accident so they will not have to pay a lawsuit and not have to fix a recall problems. I am 74 years old and been an auto mechanic all my life so I know about automobiles and wiring. I doubt that anything will be done, and wonder how many people have been killed because no one will dig deep enough into the problem to find the problem and fix it.

Every day one of my headlights are not working. One day it could be the left one, the other day could be the right one. I'm afraid both might go out during night time driving.

My headlights keep randomly turning off on their own while parked or driving, in the dark or the light. To troubleshoot I have replaced the headlights and tightened the wire connections, but the problem continues. Only turning the headlights off and back on seems to temporarily fix the problem...until the next time it turns itself off. I had a similar problem with my honda pilot 2005 a few years ago and there was a safety recall on the headlight wire harness kit that was corroded from humidity and overheating and failing. This has now happened dozens of time on my prius, mostly affecting the left headlight only, but a couple times on both headlights.

Last year my headlights started flicking on and then when I turned them off and then back on, they would both work again. Sometimes it's just one headlight, either left or right and sometimes its both at the same time or one and then in a mile or two the other making it so both are out. I've had my bulbs replaced and since looked at again and was told the bulbs were both still good. I have been told it is a very expensive process for fixing the problem but it is extremely dangerous to be driving on the freeway at 65 MPH with two kids in the car and have both headlights go out on you. It happens when I am driving. It doesn't matter what type of surface we are driving on. I happens every single time I drive my car.

Drivers side head light goes out periodically. Research on line says that this is a problem with 2006 - 2009 prius. Is there a recall? Goes out while driving.
