When in motion the left front hid light goes out. Turning the light switch off and back on (dangerous on the road at night) brings the light back on. May happen several times in one trip or maybe not at all. Weather irrelevant. Has been happening past several months.

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.

Headlight, drivers side, will go out occasionally while driving. It will come on again if the headlight switch is turned off then on.

- Riverside, CA, USA

The headlights on my Prius sometimes don't come on or may come on and turn off while I'm driving. It's usually the driver's side, but the passenger's side has done it once. If I notice it, I can usually turn off the lights and turn them back on and then they both work. It has happened both when I first turn on the lights (while stationary) and also when I have been driving for a few minutes. The problem is becoming more frequent. Hitting bumps or pressing connectors has no effect. It does not appear to be a loose connection. The bulbs work fine after cycling the switch. This has happened multiple times.

The headlamps on my Prius go out intermittently while driving. Sometimes one goes out and sometimes both. It is very dangerous when they both go out while driving at night. I can usually turn the switch off and on to get it back on, but that is uncomfortable when driving down a dark road and have to get the lights back on. This is an ongoing problem and happens regularly.

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 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.

Purchased 2006 Toyota Prius used on Aug 17, 2013 (61,500 miles). Within a month I was pulled over by police for passenger side headlight out while driving at night, but when headlamps are turned off and on again the headlight came back on, and the police officer thought he was crazy so he just issued a warning. The headlight continued to go out intermittently and I replaced the bulbs myself in November 2013 (philips hid headlight bulbs $95). The headlight still went out intermittently and I finally replaced both headlight assemblies in July 2016 by an independent mechanic (approximately $1000 at 143,000 miles). Passenger side headlight still goes out intermittently. NHTSA launched a probe in April 2009, but then dropped the investigation after Toyota said it would initiate a "consumer service campaign" to address the issue. Then there was a class action settlement in 2011, all of which the previous car owner missed. Toyota uses "campaigns" to avoid recalls. Toyota's website (https://www.Toyota.com/recall) does not list previous "campaigns" related to the VIN so buying the car used I had no way of knowing of previous "campaigns" that still needed to be addressed. Upon purchasing in August 2013 I took the car to a Toyota dealership in san marcos, tx for a steering wheel recall but was not alerted to any other recalls or "campaigns" at that time.

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

- Greenbrae, CA, USA

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.

For the last 8 years I have had the headlights intermittently go off independently of each other. Now they are going off or dimming more consistently. They have been replaced thinking that it was a bulb or headlight issue but it has become clear that it is a wiring issue. The replacement headlight is more than $600 each and I know that replacing another one will not fix the issue. There needs to be a recall because problems are all over the internet with this issue. This happens while driving at any time or sitting in the driveway with or without the motor running.

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 to $1200. Toyota has still not issued a recall for this problem

- Fremont, CA, USA

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

- Sturgeon Bay, WI, USA

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

- Sturgeon Bay, WI, USA

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

- Sturgeon, WI, USA

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.

- Spanaway, WA, USA

I noticed in the past month that the headlights turn off unexpectedly while driving. First the driver side then both headlights then the passenger side. They go back on when I turn the switch off and then on and the problem is unexpected and not reproducible. I was told at the dealer that the headlights needed to be replaced. They would not acknowledge there is any known issue with the headlights turning off by themselves. I replaced both headlights 2 days ago and will monitor the situation.

- Lancaster, PA, USA

While driving on a dark unlit windy road, the headlights seemed to be getting dimmer, then both spontaneously turned off. I had absolutely zero visibility of the road and I instinctively slammed the brakes. I was approaching a sharp turn with a guard rail and a steep ravine into a river. The car came to rest about 8 inches from the guard rail. Upon cycling the headlights on and off, they both lit up again. I turned in the fog lights as a back up and continued my drive, slowly. Since then, I have observed the lights fading and then turning off, usually only one light at a time, but sometimes both.
