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.

My driver side headlight automatically turns off randomly. And it is getting more frequent. Both headlights turned off when I was driving on a freeway the other night. If I turn off the headlight on and off, it will work normally for a while.

I noticed that my right hid headlamp on my 2006 Toyota Prius was not working when I parked my car. I cycled the lights and the lamp came on, but it did appear to be dimmer than the left headlamp. I made an appointment for Jan 2nd, 2010 at my local Toyota dealership. Note that I had the same problem with my left headlamp in Feb of 2008. The dealership replaced the bulb under warranty, but indicated that the replacement would have cost $500+ if not for the warranty. I did not file a complaint with NHTSA on the first failure.

I have the same problem as many, many other Prius owners, with my 2006 Prius's hid lights going out while driving. When I realize that one or both lights have gone out, I flip the headlight switch and they come back on, only to go out again within seconds! Toyota says this is a dealer-only item and the hid bulbs cost $300 a piece! these bulbs are not available at auto parts stores. The price is exorbitant and very unaffordable for many people. This is a serious safety issue! Toyota should recall their priuses and fix this issue once and for all instead of ripping people off and putting their lives in danger! please help put some pressure on Toyota to do the right thing.

I have a 2006 Prius with the hid headlights and want to confirm that both bulbs have failed. The dealer agreed to replace them under warranty even though I have 47000 miles on the vehicle. I did complain about this a year ago and the dealer did nothing at that time. This problem is compounded by just today receiving a notice from Toyota about an hid headlight support program that lowers the price of the bulbs to $150 per bulb. This is still outrageous.

The factory installed hid headlights periodically turn off. The first incident occurred two years ago, and I thought I had imagined it. I noticed dim lights and corrected the problem by quickly switching to bright lights. I was later told one head light was out while driving, but when I checked by exiting the vehicle both lights were on. The problem was very intermittent for two years primarily because I rarely drive at night. The problem is much more frequent now occurring multiple times per trip. I discovered that I can temporarily resolve the problem by cycling the head light switch ? not a safe tactic. An internet search today revealed this to be a common problem. Surprisingly, we have not received a notice from Toyota. This is clearly a dangerous factory defect. If Toyota will not issue a recall, please demand that they at least acknowledge the problem and issue a notice listing the parts needed to correct the problem. Please take immediate action before the problem causes serious accidents.

Hid head lamps turn off at random, one or the other, sometimes both at the same time. Turn off the lights and turn them back on and they relight.

Every two years, the headlights of my 2006 Toyota Prius begin to fail and start to turn off, unexpectedly, while I'm driving. Several times, I've driven long distances at night, completely unaware of the fact that they had shut off, and later they appear to be working fine. At 20,000 miles, I had both lights replaced by the dealership. Less than two years later, the driver's side headlight stared to fail again. The dealership paid for the light, but charged me $120 for the labor. Seven months later, the passenger side light began to fail. Again, the dealership paid for the bulb but charged me for the labor. After the third repair, I called the Toyota experience center. They said that their new customer support program would not cover reimbursing me for the labor. I'm concerned that now in addition to the risk, time and expense I've already incurred, that I will have to add "preventative headlight replacement" to my list of required maintenance of my vehicle, and it will cost me another $600 every 2 years to drive my vehicle safely at night. Because the way the hid light fail does not give the driver any warning or notification. The lights both illuminate at start up, and only fail while you're driving. I appreciate Toyota paying for some parts of the repairs, but I think they are failing to fully address this very dangerous situation, and have saddled their customers with an unreasonable expense. When you can replace a headlight by yourself every five years for a couple bucks, it's reasonable. When it costs $300 per headlight every two years, that's not reasonable. I filed a previous complaint after the 2nd time the lights failed in May 2009. This is the third incident with this car, and the 2nd time I'm filing a complaint here.

Driver's side hid headlight occasionally goes out while driving. This started a month or two ago but I'm reporting yesterday's incident because I have just found out via internet forums that a significant number of other 2006 Prius owners are also experiencing this problem. Turning headlights off then on again fixes the problem. No problem so far with passenger side lamp which has obviously been used with the same frequency and duration. This has not caused an accident yet, but if this were to happen with both headlights it would be very dangerous.

The right front hid headlamp of my 2006 Toyota Prius keeps cutting out and then comes back on when I turn the lights off. I have replaced both bulbs, but the same thing has happened. The problem started in 2008, stopped after I changed the bulbs and started again not even a year later.

After about 40,000 miles, the driver's side headlight in my 2006 Toyota Prius started blinking off (I.e., it would turn off, but then if I switched the lights on and off, it would be on again).

Passenger side head light goes out randomly. When the lights are turned off and then back on it will work for "some" period of time, could be seconds or days. Car has been taken to the dealership multiple times for diagnostics and alleged repairs yet the problem continues. Dealer has replaced bulbs & replaced some module within the circuitry. Continues to fail.

Hid headlight failure on 2006 Toyota Prius. Purchased in June 2006 right headlight and control unit were replaced in June 2007 by Toyota under warranty. Right headlight and control unit failed in Dec. 2009. Now driving with right headlamp out. Hid headlamps are supposed to have twice the lifetime of normal headlamps. Headlamps should not cost $500 to replace. Toyota has an obvious design problem with their headlight system.

My 2006 Toyota Prius with high intensity lightbulbs has less than 40,000 miles on it. One bulb has already been replaced and now I am having intermittent failures on another bulb. I understand NHTSA has decided not to take any action under PE09019 but have to say I don't understand your stance on this. I can be cited by police for having defective safety equipment when a bulb is out, yet you felt this did not warrant action. This problem with Prius hid headlights seems to be limited only to that vehicle model it is obviously a defect in design and it is a safety issue. Ever meet a one-lighted car or truck on a very dark two lane highway? hope you will take action to force Toyota to do a recall and correct this very dangerous issue.

The headlights on my 2006 Prius will go off for no apparent reason. Most of the time this involves only one headlight, but I have had both go off. If I turn off the lights and turn them back on the lights come back on. I've read several complaints on the internet on this problem. Clearly a safety concern.

For a 2006 Prius. Twice this evening my headlights went out on their own. I was driving to a store about a mile and a half away, when a half mile from my house all lights, including headlights, went out. They did not come on until I manually turned them "off" and then on again. On the way home from the store, they went out again.

The headlights on my 2006 Prius goes off while driving. Sometimes one light goes off and the other stays on. Sometimes the intensity of the lights vary. To correct the problem I have to turn my lights on and off. Also my brake light will go on and off. I have been pulled over numerous times by the police because of this problem.
