2006 Toyota Prius hid headlight (driver's side) fails intermittently. The light will go out intermittently, but will come back on I the switch is turned off and on again. This problem began several months ago, and is getting progressively worse (more frequent). I was advised by the dealer that I would have to leave the car with them so they can "watch it until it fails", which is impractical since I need the vehicle on a daily basis.

Around 40K miles headlights would shut off. First occurrence happened on major freeway at night. Immediately pulled over and turned off car. When starting car back up, headlights turned on. This problem occurs at least every other day. Big safety issue considering headlights can go off at night while operating vehicle.

Headlights intermittently go out on both the passenger and driver side of my 2006 Prius. Problem was identified by dealership as manufacturer defect. Dealership removed and replaced headlights and computers. The total cost for the repair by frontier Toyota was $1,323.86. I requested 100% reimbursement with Toyota. Toyota agreed to pay for parts only. Toyota is aware that this is a common issue with the Prius but does not take responsibility that this safety issue is a manufacturer defect. The safety issue and cost is exorbitant.

2006 Prius high intensity headlamps flickered went out and restarted when turned off and on and eventually stopped working at 40,000 miles in March 2008, had bulbs replaced by Toyota loyalty, now in April 2009 with less than 30,000 more miles same thing happening, unsafe to drive at night, Toyota loyalty refuses any further assistance, repair estimated to be over $600. Obviously defective part or design. Toyota loyalty claims that controllers were replaced in 2008, but dealer denies, stating only replaced bulbs.

There are over 800 NHTSA registered complaints regarding the 2005-2008 Toyota Prius intermittent hid headlight defect. Yet, the NHTSA has not opened an investigation. Will someone or some family need to suffer through a deadly accident before an investigation is opened?

Intermittent failure of hid headlights on 2006 Prius beginning around 30K miles. Temporarily fixed by switching lights off and on. Unable to replicate for dealership. Occurs at least once each drive in car, any mileage. Other owners have had same problems. Cost of repairs at dealership have ranged from $380 per lamp. In one case a dealer charged a Prius owner $2600 to repair the problem. This is an unsafe manufacturing defect warranting a recall by Toyota.

I own a 2006 Prius and usually have to drive to work or from work before the sun comes up or after it goes down. I do not keep my headlights perpetually on while driving. At about 40,000 miles (weeks after the warranty ends) my left headlight flickers off, but I turn the light switch quickly off and on and the light works again for a while longer, then it goes off again. I take it in and the dealer says $646 to replace one, and other will need it too, so $936 for both. Dealer says the bumper has to be dropped down to get to the lights, that is the biggest expense. When I drive it home right from the dealer the right headlight goes out too, with the same quick off/on to get it working again. Some days I can turn it on once and drive 52 mile to work without them going off, other days one or the other cut off 5-10 times or flicker for a few minutes. Many of my colleagues and friends say they drive their new expensive cars with headlights perpetually on with the same type of headlight, and have no problem or no expensive replacement costs. I fell that the shortlived headlamp is a product defect and bizarre process to drop the bumper to replace the headlight is a manufacturers defect.

Drivers side headlight goes out after being on 1st. After the headlights are on, the left(drivers side) headlight simply goes off. If I turn the headlights off again, they both come back on, and then again, the drivers side headlight goes back off. Prior to this issue, both headlights would go off, I would turn both headlights off, back on and they'd be fine for a little while, and the cycle of off and on, on and off would continue!

Safety issue: My 2006 Prius hid headlamps only work intermittently. One or the other will randomly go out. Cycling power usually fixes the problem.

Both headlights turn off, separately and intermittently. Must turn the headlight switch off and on to turn light(s) back on while driving. Increasing in frequency.

Headlight goes out intermittently... turning off all lights for several seconds and then back on turns the light back on.... dealer said bulb needs to be replaced for about $300..... internet forums indicate this is a problem with the Prius over several years... and does not fix problem... others have replaced controller boards, bulbs, wiring, all to no avail... there should be a recall to fix the problems.... I have also purchased the extended 100,000 mile warranty.

The headlights on my 2006 Toyota Prius blink on and off. Sometimes the left sometimes the right and sometimes both. The failure occurs almost daily and sometimes multiple times a day. When the lights turn off usually turning them off and back on will make them work again. Brought my car to Toyota and they told me that I had to replace the complete headlight unit and casing on both sides (cost $350 each plus labor. Total cost about $800) I found that the headlights are not sealed units as I was told and have not had them replaced yet.

Passenger side hid headlight goes out every 3-4 months. At first it is intermittent, and difficult to say when failure occurs. Over time the period for failure gets shorter. Dealer says it is my problem. Cost of continual repair is over $300. Per light. Also, fuel gauge say add fuel when tank partially empty.

Driving at night, the passenger side headlight sometimes goes out, sometimes works. I would say it works 25% of the time. This results in limited visibility when driving at night. At this point, nothing has been done to correct the failure because the headlights are very expensive and so far there has never been a total loss of visibility.

Hid headlights fail during operation and the driver has to turn power to the lights off and then back on for lights to turn back on. This cycle has to be repeated every 0-5 minutes since the lights continue to burn out.

I have 2006 Prius. The passenger side headlight is intermittent. I have noticed this for about 2 months now. It has 35,000 miles. Have been reading this is quite common in 2006 Prius yet Toyota has not offered recall. Obviously driving with a headlight out is not only a safety issue but a legal issue as well.

The contact owns a 2006 Toyota Prius. While driving 70 mph, the headlights failed. The contact turned the activation switch on and off and the headlights illuminated again. The failure has occurred on numerous occasions. The headlights will shut off without warning even when the vehicle is idling. The vehicle was taken to the dealer and they stated that the two front headlights would need to be replaced at the cost of $600 per light, plus labor. The vehicle has not been repaired. The contact called the manufacturer and was advised to take the vehicle to the dealer because there were no recalls. Therefore, no compensation would be provided. The failure mileage was 52,000 and current mileage was 58,600. 4/01/09 updated 04/06/09.

Toyota is familiar with the hid lights on their Toyota Prius' and even issued a tsb (T-sb-0030-08) and is still requiring the end user to pay upwards to $800 for the repair. Within the last few weeks, I am having to turn my headlights on and off in the day or during the night so that I can have both lights on. It's an intermittent issue and many other owners are complaining about the same issue. It is a tremendous safety issue especially when driving at night. For the 2010 model Prius, Toyota has even taken out the hid lights. What is really going on here. I am not a happy consumer.

Headlight goes out. Later it comes back on and then goes out again unpredictably. This could be very dangerous depending on where I am driving when it happens.
