My driver's side headlight doesn't stay on. It will go on for a minute then turn off. If I turn the headlights off and on, it starts back up again, then goes out again. I replaced the headlight control and it still continues. It does this if I'm driving or not.

My headlight intermittently goes off while driving & then back on. I paid a local mechanic to check it out; he couldn't find any loose connections, etc. But did advise me of a class action suit for this exact problem on the 06 - 09 model yrs. I've contacted both a local dealership & Toyota Corp. Who both refuse to fix it at no cost to me (see attached response from Toyota Corp.

Left headlight is dim, goes out, comes back on when lights are turned off and then on again, but then dims and eventually fails again. This happens whether in motion or stopped, regardless of speed, and whether turning or going straight. I read that this is very common among 2005-2009 priuses, and a design change in 2010 fixed it. That means it is caused by a design problem, and Toyota should do a recall to fix it.

The headlights are going on and off while driving. They will stay on for a few minutes and then the left or right one will go out so then I'll reset the lighting and it will come back on and then I will go out again. Sometimes the right sometimes it's the left sometimes it's both.

One headlight or both will randomly go out while driving. Has happened sporadically 6 or so times over the last 6 months, including this evening when both headlights failed. Totally random, can happen on short or long trips, city streets or highway. So far lights have come back on by cycling the light switch on and off

Both headlights will flicker and go out, mostly at different times than the other but can happen at the same time. By turning the headlight switch off, then back on after 10 to 15 seconds they will come back on. Driving on the freeway this leaves you in a very dangerous situation. Thank god for fog lights, a life saver at 70 miles an hour. This can also happen sitting in my driveway before leaving for work.

One of my front headlight always goes out once I make a turn by using a turn signal. If I switch the headlight off and on again, the head light will come back. I read similar post from website, and found some people have the same problem with me. We all suspect this is a design problem by the manufacturer.

Head lights turn off after being on for a while. Turning off headlight switch and turning it back on turns the light back on. High beam stitch does not affect the light which is off. This happens while in motion on both highways and city streets. This occurs frequently

Headlights go off, one at a time, intermittently, while driving on any road. If I turn the lights all the way off and then back on again they will usually stay on for 15 minutes before going off again. I am not aware that they have both gone off at once, but I have not driven the car at night yet

I was driving through Nevada at 11 pm at night towards reno (approx. 180 miles away) on I-80 at 75 mph when suddenly my headlights went out. I immediately tried turning the lights off and on manually with my left hand, and the lights came on again (I couldn't see anything in the dark, scared out of my mind). Then, about 2 minutes later the same thing happened (I was driving slower this time). I did the same turning off and on again, and the lights came back on again, although somewhat dimmer. A few minutes later (5 minutes?) I was passed by a vehicle, that then slowed down and came in behind me, and then turned on the police lights and I immediately pulled in an exit ramp (fortunately there was one right there). After the policeman checked my license and registration, he informed me that one of my headlights was out. He asked me to try and flick on and off the lights a couple of times, and to try the brights, but none of this brought it back into working order. He then out of the blue mentioned to me (without me bringing this up) that the Prius' were notorious for having intermittent issues with the headlights, especially on the passenger side of the car (which is the side that was out, coincidently). He let me proceed using one headlight without ticketing me. A few miles later I pulled into a rest area and turned off the car for a few minutes while I went to the bathroom, and when I got back into the car and turned on the headlights they both came on, but within 20 seconds the passenger side light went out again. When I got home the next day and turned on the headlights they were both working again. This intermittent failure of the passenger side headlight has occurred a few times in the past, and I have had the toyoto dealer look into it and they claimed that it was fixed. However, this time it was life threatening.

Left and right headlights sporadically turn off which is extremely hazardous when driving at night in roads without street lights. Definitely a safety issue which Toyota must issue a recall. Light bulbs are not the issue. The issue is in the computer or balast that controls the lights.

Headlights will randomly go out while driving. Most of the time it is only one headlight but sometimes both go out. To "re-light" them you have to turn the headlights off and then back on. Replacing the bulbs does not solve the problem. At night this has almost led to disastrous effects and, from a risk management perspective, it is only a matter of time before something bad does happen as a result of losing your external headlights while driving at night. It happens whether the car is stationary or in motion. Some element of this happens every time I drive the car (multiple times per day).

Driver's side headlight went out in 2015 and was replaced by local mechanic. Before it went out it had flickered but came back on. I was driving at night when it went out and was pulled over by police. Fortunately I only got a warning. March 2016 the headlight went out again (I noticed it in my driveway) and was replaced at a Toyota dealership on 21 March 2016. That very day, the headlight went out again (noticed it in my driveway). It would come on periodically but kept going out. 25 March 2016 the Toyota dealership replaced the "computer sub-assy, H" for $458.52. 28 March 2016, the headlight is out again (noticed it again in my driveway).

The headlights (hid) stop functioning intermittently. One or the other or both will randomly shut off. The lights will come back on if they are turned off then on again. The issue has been happening for several months.

While driving the passenger side headlight went out, I replaced the bulb and the problem continued. It turns off shortly after starting the vehicle wether it is driving or sitting, when I turn lights off and on again light will turn back on for a moment and turn off again, this happens while I am driving and I am afraid to drive it and be pulled over for not having working headlights.

I was driving at night on the freeway 280 and suddenly both headlights went out, it was so black you couldn't see anything on the road. Talk about scary, try driving at 65 mph on a road that curves when you all yo can see is black. I was able to jiggle the switch the headlight switch off and on several times and the lights finally came back on. With my heart pounding I continued to drive home only to have both headlights again go out together. This happened 6-7more times until I reached home. I was actually shaking by the time I got out of my car. Why were both headlights malfunctioning at the exact same times" I took the car to the dealers the next day and after inspection they told me I simply needed new headlights. I thought it was an electrical malfunction, but they insisted that it was just the headlights going out and that this happened all the time. Why would they be using headlights that they know both go out at the same time?"this is highly dangerous. People could have a heart attack if not an accident! I spent $500 to replace the two headlights. However, I just recently experience the exact same problem of both head lights going out. My car is at the dealers this very moment for the same problem. I hope my 2005 Prius gets recalled for this headlight problem so other people to not have to experience this trama and dangerous situation. I was surprised to learn that this headlight problem is common to the Prius. Outside of this dangerous headlight problem I love my Prius.

Digital dashboard sometimes is completely blank for extended periods so that I can't see my speed, fuel levels, odometer, and other info. When I start up it happens and continues the whole time I am driving. It is causing other problems related to the hydrolic braking sometimes as well when this happens.

Me and my family traveling down the interstate at 70 mph in the dark when a tractor trailer all of a sudden started to change lanes when we were directly to the left of it. Luckily the lane to our left was open and we were able to quickly change lanes to avoid collision. It turns out our 2005 Prius headlights were not working and the truck did not see us. Had to turn lights off then on again to get them to work. The rest of the way home one light would go out, then the other would go out. Had to turn switch off then on again to get them to turn on again. This is definitely a major safety issue with this car. Why is there not a recall.
