Headlights problems of the 2006 Toyota Prius - part 1

Headlights constantly go out. Research online proves Prius vehicles with hid bulb systems have ballast issues causing constant blowing of either bulbs or ballast failure. Not only is safety constantly compromised, but it is illegal when a headlight goes out driving down the road.

While the vehicle was in motion on side street traffic at maximum 40 mph the right headlight turned off and I was pulled over for a traffic violation. The headlights were both working when I left my house 10 minutes earlier. They were both working when I left work later that day. The lights have had this problem before on and off frequently on the highway and side streets, but every time I check after pulling over and turning the car back on both lights are working.

The hid headlights are both out, after being on maybe 5 minutes. From everything I have read online and from my mechanic, this is a known issue with my model of car, that has been going on for years. The ballast is faulty, and would need to be tested prior to replacing a hid light. This has been happening for months, and I simply do not drive at night as a result. With the time change, this is to difficult.

Both of my headlights went out at the same time the other day now the fact that both of them went out at the exact same time already tells me that its not the bulb,ballest or anything other then an electrical issue because everyone is having this problem and they have changed both ballasts and bulbs and the same thing happened over and over again, please make this a recall because it is very unsafe.

Right front headlight randomly quits while driving, it has been doing this for the last 2 years.

Problem with intermittent hid headlight operation failure, drivers side failure even on high beam when driving, turning off/back on light comes back on but may fail again. Passenger front headlight works fine.

The drivers side intermittent headlight has long been a problem with this vehicle. This was a reported safety issue that was widely ignored which violates California law. I finally took it myself to get replaced after not getting any help with my reporting. I would like to receive a refund for the problem that is a recall issue.

Sometimes as I drive the vehicle, after a while, either one of the headlights turns off randomly. I don't always notice when it happens, other than when pulling up behind another vehicle at a stop light and notice that there is only 1 headlight reflection coming from my vehicle. They both work normally if I turn them off and on again.

I have had too many headlight issues throughout the time I've had my Prius. I've had the entire assembly replaced once, repaired once, replaced countless overpriced bulbs, and still consistently is a problem. At this time, I'm currently experiencing electrical issues. My passenger headlight went out again. I replaced the bulb and nothing. Not even a buzz noise. But when I disconnect the bulb and turn on the headlight, I can hear the buzz sound on both headlights. I am beyond fed up with this Prius and Toyota in general. It's been one problem after the other. The service department is a joke, every time. I had to fight them for an entire year about a warranty repair that I was repeatedly denied by several managers until I finally went to corporate and complained and that's when they finally agreed to fix it. At this point, my passenger side headlight doesn't work, and now the drivers side headlight goes out several times per drive, doesn't matter if I'm on a city street or a freeway. Some nights it occurs more often and the light blinks, even if stopped at a light. I'm almost afraid to attempt to change the bulb, what if that one decides to stop working as well even with a new bulb. Toyota wants an astronomically rediculous amount to fix just the passenger side, at almost $1200. That doesn't even include the drivers side headlight issue. I will never get another Prius ever again.

Headlight intermittently shuts off. It will later come back on again. Same with a tail-light. There are lots of complaints about this please come up with a solution. It seems to be an extremely expensive fix at a dealership due to defective parts.

I believe its a glitch in the car's computer. At unpredictable and intermittent intervals the electronic heads up display does not operate. This leaves me with no speedomoeter, no fuel level indicator, no bright or dim indicator for the headlights, and the cruise control does not work. During the incidents the car also might not respond to the power off button, so it keeps running. This problem might last for a day or two and then it starts to work again.

The passenger side headlight intermittently turns off and on. The lightbulb is still functional. This will happen wether I'm driving or stationary.

The headlights on my 2006 Prius have been going on and off sporadically since appx. 2010. First, only one headlight on the driver's side would go and off. I asked my Toyota dealership multiple times about the problem, but they could never correctly diagnose or fix the problem. I was stopped more than once by the police for having a headlight out. Usually if I turned the headlights off and then on again, both lights would turn on. In 2014 I had both headlights replaced by my dealership, which cost over $1,000. In June of this year (2017), both headlights starting going out at the same time, and I took it in to my Toyota dealership. They said they could not get the problem to "repeat" while they had it in for service and offered other help or explanation for solving the problem. This is a very dangerous problem because the lights will often go out unexpectedly when I am driving at night.

While driving the right headlight will flicker and turn off. It can be turned back on by turning off and on the headlights. I got pulled over last night because I couldn't tell it had turned off while driving in town at night. I can tell when it goes off while driving in the country and get it to turn back on. I have read many online forums that dealerships will replace many expensive things trying to fix it but it still does not fix it.

Car I purchased for my daughter, had its headlights go out last night in the rain as she was taking an exit off road. Fortunately no one was hurt but she is very shaken up. She said the lights just went out leaving here in almost complete darkness.

Three times in the last 12 months the headlights have failed on this car.

The contact owns a 2006 Toyota Prius. While driving 20 mph, the headlights malfunctioned. The contact could not see the road in front of him due to the malfunctioning headlight adjuster. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 105,000. The VIN was not available.

Toyota Prius 2006 right headlight will spontaneously and at random turn off. It happens when you are driving the vehicle. Often the car will illuminate both headlights and it is only after driving several minutes, the right headlight will turn off. Very difficult to reproduce. I feel this is a significant safety issue. Cost estimates from research have been shown to be $400. 00 to $1200. 00. Toyota has still not issued a recall for this problem.

This is the second failure of the headlights on this car since I bought it in late 2015.

The contact owns a 2006 Toyota Prius. While driving 45 mph, the driver side low beam headlamp failed to illuminate without warning. The failure was rectified by turning the light switch off and on. The failure recurred intermittently. The vehicle was taken to the dealer where it was diagnosed, but the cause of the failure was not found. The vehicle was not repaired. In addition, both the driver and passenger side headlamps failed to illuminate without warning. The manufacturer was made aware of the failure. The failure mileage was 110,000.

This was the first of three headlight failures in the the year that I have owned this car.

Passenger side headlight failure.

Headlight goes out without warning!!!!.

The headlights flicker and then go out. It is necessary to turn off all lights and then turn them back on. The same thing happens after a short period of time. This happens when the car is moving and I have been pulled over because I was unaware that the lights were out while driving in the city.

One of the headlights worked sporadically. It happened the same day I purchased the car used from a Toyota dealership, but I didn't notice it right away because it was daytime. The next day I went to the service department and they said I needed to replace the hid bulb which costs $300!!!!! after complaining to the dealership they replaced it at no charge, but I am concerned that this might be a recurring problem. I don't know if they replaced any associated parts or not, since the invoice they gave me just listed "engine elecrical concern" without an itemized list.

Driving along and the headlights just go out in he middle of the night. Faulty headlights.

I have been having problems with the hid headlights since I bought this car. It's not the bulbs, there is some computer problem that is recurring. I think they need to recall this car and fix the problem.

Right headlight went out while driving at night, reducing visibility to only nearly 20%-30%. This is very annoying and dangerous as the vehicle may be taken for a motorcycle especially in parking lot as others might mistake the vehicle width and resulting in collision. However, the light is restored by flickering on and off. This also occurred while driving on the freeway at high speed. Flickering maybe be a hassle while driving at such speed.

Passenger side headlight goes out after being on for five minutes and can not be repaired.

We have owned this 2006 Prius since new. We have replaced the headlights many times. This last incident was similar to the rest. The headlight on the right would go out but it was an intermittent loss. There was an ability to get it on again by flicking the headlights on and off. After a week of this, the second headlight started to do the same resulting in total headlight failure. This could also be remedied by flicking the headlights on and off.

My 2006 Toyota Prius headlight goes off when driving. It flickers first and then goes off. Sometimes one light goes off and sometimes both of them. When I turn the light off and turn it back on headlights work again. But after a while they turn off again. They stay on steady after I drive for more than an hour in long trips and after turning it off and then on again several times.

Headlights, one or both, randomly go out while I am driving. I had the dealer look at it a year ago and they said there was nothing wrong. It continues to happen and is really scary when I discover that I am driving without lights on a busy highway. I am now taking to an independent mechanic to fix the problem. This is clearly a safety issue!.

Left headlight goes out. I have to turn both headlights off, and then turn them back on for left one to work again. I had this problem years ago, and the dealership replaced lamp for $600, but now I'm noticing the problem again. Very dangerous ! dps thinks it's dangerous, too, judging from warnings I'm collecting.

Right passenger headlight went out. Was able to get it back on by turning the lights off and on. On the drive to the dealer to get it fixed, left driver side headlight went out. Again able to get it back on by turning it off and on. Dealer checked over the car and only replaced the right passenger side headlight even though I told them both had been out. They said there was nothing wrong with the left drivers side headlight. Drove away from dealer and the left drivers side headlight went out after I drove less than 1 mile. Went back to the dealer, but did not turn the lights off and on. He could not believe it, but the light was out. Had the left drivers side headlight replaced. Is this some kind of electrical problem? this could be very dangerous if both went out while driving!.

Driving down a dark road both my headlight went out. I almost wrecked. I then turned them on an off and they came back on. This si the second 2006 Toyota Prius we have owned with the same issue. There should be a recall. . . . Does someone need to die over this common isssue?.
