The drivers side headlight goes out on its own, a few minutes later the passenger side light will go out on its own. Leaving no lights, if I turn them off and on again the headlights will work again but not for long periods of time. I have replaced the bulbs in both and they will work for a few months with no issue and it starts all over again. This has happened numerous times since I purchased the car and now I learn they got out of recalling because both lights don't go out at the same time, well mine do.

The headlights on this car flicker and go our with very little warning while driving in the city and on the highway. We were almost in a very serious collision when the lights went out without warning while driving at night on the highway. Sometimes turning the lights off and on again will get them to work for a while, but is is happening so frequently that we cannot drive the car at night anymore. I have see many hundreds of complaints about this online. Would it take the death of my family to get Toyota to recall and fix this dangerous defect"?"

The right hid headlight on my 2007 Prius shuts off intermittently when the car is in motion. The failure is intermittent, and it is unclear when it first started and how frequently it occurs. The headlight turned off last week and made it dangerously difficult to see a pedestrian on the side of the road. There was no incident, but the experience was troubling. Toyota has disclosed issues with hid headlights in their "2006 through 2009 model year Prius hid headlight customer support program" and offered to reimburse the full cost per conditions in owners warranty. After a 30 minute phone call to the local Toyota dealer and them 60 minute call to the Toyota customer service experience center the discussion re-enforced that there was ¿no way¿ to cover the cost outside of the 5 year 50K mile warrantee and thus am supposed to pay $300 to the dealer to fix the defective headlamp and ECU that is probably the actual source of the defect (lamps generally work a long time if they get correct/stable source current). For several years I inquired during annual state inspection checks to check the headlights as I sometimes had trouble seeing at night. The lights worked when the car was not in motion and hence always passed inspection. The Toyota five-year warrantee seems arbitrary and not relevant for intermittent failures that may or may not have been diagnosed within that time window. Toyota should be culpable for fixing the defect cars identified as having the problem. It seems unfair for Toyota to belatedly announce a known defect but limit responsibility to time or mileage of an owner's warrantee. Shouldn¿T potentially hazardous defects be serviced by Toyota regardless" why should Toyota collect service payments from customers to drive a vehicle with headlights that stay on all the time when they know they don¿T work and crap out"

I have endured the same headlight issue that I see endless numbers of people have commented on here on the NHTSA site. I have 110,000 miles on my 2007 Prius and have been experiencing regular outages of my right headlight for 80,000 of those miles no matter what the "fix" has been. Toyota dealerships I have taken my car to over the years all claim that this is not a typical problem and yet it appears from this website that it is most certainly due to some sort of faulty design/parts. My right headlight will be on and flicker off after a few minutes of driving. If I quickly turn the lights off and then back on as I drive, it will turn back on for a period of time before flickering off, once again. My cousin's 2007 Prius and my fiancÉ's father's 2004 Prius had the exact same issue with a single headlight. Obviously, this has proven to be a highly dangerous problem when driving at night and in all kinds of weather-related situations and would appreciate the NHTSA's assistance in investigating this as a potential recall for us Prius drivers.

The headlights on my Prius randomly go dark. Sometimes 1 headlight and other times both. Turning off the light switch and then back on is a temporary fix. The problem comes back minutes later. This is very unsafe for myself and other drivers on the road. This happened while I was on the interstate going 70 mph last night!

The drivers side headlight goes off. There is no pattern as to when it happens. The lights must be turned off then back on for it to light again. The car was taken to the dealership for repair + 1 year ago. The service was paid for, to no avail. Thought continues to go out. We ha E been pulled over by police officers for ha ok nguyen a light out. I feel this is a salt F etc issue and it appears it is a problem with many Toyota cars. Something needs to be done.

Right front headlight goes out intermittently. Cycling lights off and back on used to correct problem temporarily, but now headlight stays on for only a minute or two. Had similar problem with left front headlight and had hid bulb replaced in 2012 at great expense. Problem occurs when lights are turned on or while driving. This is a safety concern and a known defect that Toyota should correct free of charge.

My wifes 2007 Prius headlights continue to flicker while driving at night. Then one side or the other will go out. The headlights have been inspected by 2 certified mechanics neither can find any faults in the headlights or bulbs even applying contact grease to assure electrical continuity. Attention NHTSA administrators ( this certainly could become a deadly problem.) we have had both lights go out simultaneously. The driver must immediately turn the light switch off then on to restore lighting. I hope they never fail to re-light!! of all the problems- attention surely must be given to these lights. Almost a thousand complaints many people keep taking this problem to the dealers, only to have it repeat itself? immediate action is required by the NHTSA.

The contact owns a 2007 Toyota Prius. The contact stated that while driving at various speeds, the instrument panel lights failed to remain illuminated. The contact stated that the failure recurred several times. The contact also stated that when the failure occurred it was impossible to shut the vehicle off without removing the negative battery terminal. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 130,000.

Head light get turned off while driving. Left side head light goes off more often than right side. Right side headlight goes off while driving too but not often like driver side. I replaced hid light bulb and computer controlled ballast. But the symptom is not changed. The worst case frequency off was every 5 minutes.

My left front headlight intermittently turns off. They do eventually turn back on, but it seems incredibly dangerous to be relying on one light for that time. I've spoken with a few other owners who have had the same problem. I had to get it replaced for $200

The right hid headlamp on our 2007 Toyota Prius has an intermittent fault. It goes out and then will come back on. The duration the hid light goes out varies, and it may work for several weeks before failing again. This problem has been occurring since we purchased the car new in 2007. Earlier, the dealership replaced the light bulb and power supply modules (under warranty). That seemed to have fixed the problem, but now it the problem is occurring again. We notice the problem while driving at night, I've been unable to identify a pattern that suggests it may be a loose connection (such as, occurring on rough or bumpy surfaces). So far the problem has only occurred in one hid headlamp and not both at the same time. Which has the potential to be a serious safety issue.

One hid headlamp will occasionally turn itself off. Turning headlamp switch off for 3-5 minutes and then back on will correct the issue. As one could imagine, very problematic when driving on the freeway at night. Multiple bulb replacements (over $150 each) have had no effect. Dealer recommended full headlamp replacement is over $1000. Research found that many others have had a similar issue, and eventually trace the problem back to the ballast of the hid lamp, which is easily damaged by water from poor design (the ballast is weather-sealed against the engine compartment, but not against the headlamp itself; any water that makes its way into the lamp will run down and pool on the ballast electronics).

My headlight comes on but goes out intermitently. If I turn the light off and turn it back on it comes back on. I;ve read about other people having this issue and heard that replacing the expensive bulb sometimes doesn;T fix the problem and there is a class action suit on it.

While driving at night the headlamps will randomly and somewhat frequently just go out. If I turn the switch off and back on again they will come back on. This is very dangerous because it is not always obvious that they have gone out. I have read that many other people experience this problem and a recall should be issued.

The headlights go at without warning. Sometimes one goes out sometimes both while we are driving. Bulb replacement does not fix the issues. This has continued to be a problem for years. Toyota service has not offered a fix that works! I have been driving on the highway or local roads when, all of a sudden, all the lighting goes dark. I have had success in relighting the headlights by turning off the headlights at the main switch and then turning them back on. Extremely dangerous. Breaks are also a menace: On wet roads it is especially noticeable when using the breaks. If you are breaking and a tire goes over a more slippery surface than the pavement, such as a manhole cover, the ABS system cuts breaking to all the wheels such that the car continues on as if the breaks are not being applied - the car effectively releases the breaks and you loose control of the car until its systems decide to return controls to the driver. This happens over and over and over. Try it on a road with a bit of loose gravel on it or the leftover coarse sand from winter road maintenance or going through a milde pothole where gravel has spilled onto the road....breaking in these conditions will consistently cause the car to diminish breaking power to such an extent that the car is no longer lowing down. We own 6 cars of varying makes and this is the only car that has this issue. The other side of this same issue is that if you are pulling out into traffic and a drive wheel hits a slightly slippery patch, the engine power is cut for so long and so severely that we are at risk of being hit. This happens every single time. Toyota service has not offered a fix. Though we have told them abou this issue repeatedly, they typically do not write it down and tell us it is normal. It is not normal or safe.
