Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

This is a known problem with 2007 Toyota Prius... headlights on my Prius go out intermittently posing a safety hazard while driving at night. Either one headlight goes out or the other. You have to turn headlights off and on to correct. There were 2 occasions when both headlights went out at the same time. I was driving home on the freeway late at night and could have been killed. My mechanic informed me to replace the left and right front headlight ballasts and bulbs. This is a major safety hazard and Toyota should be held responsible!.

Problem with lighting turning off at night without warning. Both lights turn off at different times. Upon turning off and back on they turn on but turn off soon thereafter. Apparently known safety issue subject of lawsuit and settlement for low mileage car. NHTSA should compel manufacturer to fix the problem.

Toyota recall 2007 Prius' due to faulty high-density discharge headlights. Headlights are a safety hazard and go off and on while driving at night. At times both headlights have gone off. Toyota should take responsibility and repair. It is their fault! not mine. I cannot drive at night due to this problem.

When I drive my car with the lights on they randomly turn off. We have tried twice already to try to tighten this and it still turns off while driving. The bulbs are in good condition. I have kids and feel this unsafe to be driving.

The headlights come on together but the passenger side will randomly go off while driving. Usually they come back on when I turn them off and back on. One time they both went off while on a highway and I could not get them to come back on. I drove to the hotel with out the headlights, the next day they worked.

The headlights of my 2007 Prius go off unexpectedly while driving. I have learned that if I then turn the switch off and on again they will come back on, but only for a short time. This has occurred as many as eight times during a 45 minute drive. At night on dark roads this is dangerous. I have had three near-misses as a result. Toyota had issued an "enhanced warranty" (5 year 50K miles) because of the many complaints filed around this situation, but I purchased my Prius used, older than 5 years, and more than 50K miles. I have spoken to Toyota North America, obtained case #1609193626, but they refuse to cover the cost of repair. Local Toyota service centers also refuse to do the repair work unless I pay full cost out of pocket. At this point I seem to have no options but to pay the cost myself, which I understand can be as much as $1,500!

Headlights go out while driving, and come back on when headlights are switched from on to off then back on again. This can happen 1 time during a trip or multiple times. Diag of issue is not easy and usually multiple parts are replaced trying to fix the issue.

My headlights began flickering intermittently about two years ago. Dealer said nothing is wrong because they worked when I was there. 18 mos ago the driver side went out. Bought two bulbs but before I could replace the driver side came back on again and the passenger side went out. Then they went back to being intermittent - as they are now. Basically they flicker or go on and off. Ridiculous.

One or both of the Prius headlights will switch off on its own and I have to turn off the lights and turn them on several times in order for the headlights to stay consistently on. This is a serious safety issue when I am traveling at highway speeds at night and lose my headlights and then have to switch them on and off to make them work.

Headlight burned out; they want $ 450 to fix. Researching, we find that this is a known safety issue, subject to multiple legal actions, including class action. Their current "customer service" solution? "sue us!!"

The ballists inside the two front headlights intermittently turn on/off. Both lights went out at the same time while night driving, causing a serious safety concern while the vehicle was in motion. The vehicle has 120,000 miles and both lights randomly turning off/on is not safe and Toyota should incur a recall.

Bought 2007 Prius used and everything worked. Now the driver side headlight wont work after several new lightbulbs and a ballast have been changed. It has never been in an accident to my knowledge, I would like to know if Toyota will fix their problematic vehicle.

One or both headlights will randomly turn off while driving. Mechanic was unable to find a problem to fix. This is very dangerous when traveling on the highway at high speeds. Toyota needs to recall this vehicle and fix the problem!

The right headlamp low beam works intermittently, I turn it on and off and it usually works again, my online research indicates this happens to many other Prius owners and no recall has been issued as of yet

I am the original owner of a 2007 Prius. While driving, the car headlights shut off randomly. Sometimes it is the left, sometimes the right, and sometimes both. One way of fixing the problem is to turn lights off and immediately on again but the problem would reoccur again randomly. I keep checking to make sure the lights are on and have had many drivers flash at us since the lights are off when I don't even know it. I am now afraid to drive the car for safety reason. Both hid lights have been replaced less than 2 years ago. The problem is unlikely related to the bulbs since turning the lights off and on would temporarily fix the problem. After researching the web, it appears that this is a common problem for this generation of Prius. I know there was a class action filed several years ago but there is no recall for this issue. I want to raise the awareness of this issue again and I'd obviously like Toyota to do something to fix the issue since driving at 65mph last night and having both lights simply turn off was a terrifying experience.

As indicated by numerous other owners of this car the headlights go out, then you turn the lights off and on, and they come back on for an undetermined amount of time again. It happens when driving, sitting at a light, or any time when the car is running. It doesnt matter what speed you are at or the temperature outside. I'm not sure of exact date when it started but it was around 45,000 miles and it was out of warranty because we owned it since new and took it to our dealer who could do nothing for us. We changed the bulb ourself...numerous times now. I love the car other than the headlights. There are thousands of others of people out there with the same problem. Its a safety issue.

This is the well known hid problem on my 2007 Prius. My car didn't reach the 90K miles yet and some cases the driver side hid buld sometimes does not come on after I turn on lights or sometimes it goes out while I am driving. One random way of fixing is to turn lights off and immediately on again. I am just about to replace the hid bulbs in pair first to see if this solves the problem, then maybe the ballast is the next on list as I figured out from the info available on the web.

While driving, at night, both headlights went out (went dark). Since I was near home, within my subdivision, I stopped the car immediately and switched the lights off and then back on again. The lights came back on, so I drove home and have not driven the car after dark, again.

56K on my 2007 Prius. Driving last night on a dark country road and the lights flickered then went out. Turned them off and on and they came back on but it repeated all the way home. Now I cant drive at night till I get this fixed. Come to find out its an issue with these cars. Does someone have to die to get this taken care of?
