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.

2006 Prius hid lights intermittent. While driving on a dark road on the way to work my lights went out, I turned off and turned on my light switch to get the lights to go back on. Luckily the road at the time was straight. If not I could had easily driven off the road and possibly traveled into a ditch and flipped over.

I own a 2006 Toyota Prius with high intensity discharge headlights. I have had numerous issues with the headlights malfunctioning. I have had one assembly completely replaced on the passenger side of my auto. Currently, the driver side light is also going out. The dealer has refused to repair the driver side light as Toyota has deemed the issue is not covered under my warranty and would result in an out-of-pocket cost of over $400. This poses a serious safety issue as the lights only work on an intermittent basis. Based on my research, I have determined that this issue is a pervasive issue with the 2006 Toyota Prius. There is a 130 page message board thread about the issue here: I strongly believe that this is an inherent issue that Toyota should address for all of the owners of a 2006 Toyota Prius with hid headlights. Thank you for your time.

I am filing a complaint regarding my 2006 Toyota Prius with regard to the headlights. I am experiencing the headlights turning off unexpectedly while driving at night. I have approximately 50,000 miles on the vehicle. I was told at the Toyota dealership in anaheim, California that it would cost me almost $500 to replace the headlamps but have since read that this is an ongoing problem with other Prius owners with approximately the same model year and mileage. I feel that this should be the responsibility of Toyota to recall this problem and have it fixed.

Headlights (both, but so far just one at a time) turn off intermittently. Can't tell when it happens. Notice it in a reflection from the car in front. Can turn lights off and then on again to make them work. Just never know for how long.

I own a 2006 Toyota Prius. The left front headlight failed and was replaced on November 10, 2007 for $522.05. It failed again on May 8, 2009 and was replaced today for $274.28. The right headlight failed on January 1, 2008 and was replaced for $$187.50. The right headlight failed again on February 16, 2009 and was replaced for $272.64. There are nearly 500 NHTSA registered complaints regarding sudden loss of headlights on the 2005-2008 hid headlight equipped Toyota Prius automobiles. These complaints all describe an identical defect in the headlight systems of these cars: One or both headlights will unexpectedly shut off while driving the automobile. Clearly, having one or both headlights unexpectedly shut off while driving, especially at night, is a serious safety issue. In addition to the almost 500 registered NHTSA complaints there are hundreds of internet forum posts documenting the Toyota Prius hid loss of headlights issue. The NHTSA registered complaints and the forum posts provide a wealth of data describing the problem including: Accounts of suddenly having both headlights shut off while driving at night in traffic, Toyota's inability to provide a definitive overall fix, Toyota service department's failed attempts to correct the problem on individual cars, consumers paying for parts and service that do not correct the problem, consumers being forced to call Toyota corporate in order to get at least partial reimbursement on the up to $1,800 repair costs, repairs that last only few thousand miles, etc.

Intermittent functioning headlights in my 2006 Toyota Prius. I already had my passenger side headlight replaced by Toyota dealer under a technical service bulletin. The same problem occurred with the drivers side headlight. When looked at by the dealer the first time (mileage at 39K) no issue was found. Headlight went off and on intermittently for several months after that. When looked at by the dealer the 2nd time they indicated the ECU and hid bulb needed replacing for about $650. Not covered by warranty due to my mileage being at 45K and the warranty ended at 36K. This is a very common and well known problem with the Prius's so I believe the repair should be covered by Toyota.

I have a 2006 Toyota Prius. About 3 months ago, I began to have an intermittent problem with the right headlamp. It will turn off while in use. The problem is solved by turning off and turning on the headlights. It only occurs after they are already in use. As I said, it is intermittent. It also occasionally flickers while in use. Toyota will only replace the entire headlamp, and charges around $500 per headlight to do it. The headlamps are hid, and from what I understand were supposed to last the life of the vehicle.

I have been experiencing a periodic failure of the high intensity discharge (hid) headlights on my 2006 Toyota Prius (package #6) with about 42,000 miles. The headlight that fails is usually the driver's side. I can get it to turn back on by turning off the lights and then turning them back on again. This happens occasionally, but seems to being happening more frequently over time. The dealer advises the repair is on the order of $500 and requires significant disassembly of the front of the car. I looked at a discussion forum for the car ( which listed many similar experiences (some identical) for both the 2006 and 2007 models with hid headlights. The fact so many headlights fail the same way and at the same frequency indicates ac system problem. Toyota does not have a recall on this problem.

Like all the other notices from 2006 Toyota Prius owners, between 55,000 and 60,000 miles, the headlights of my 2006 Toyota Prius began an intermittent turn off while driving. The headlights came back on after turning the lights on and off quickly (a safety issue in itself!). started with the drive side light, then the passenger side began, which made me fearful of losing my headlights totally while driving. Was told that the "balast/computer" overheats & shuts down. Good solution to prevent a fire, I guess, but not good for driving safety. Replacement quote was $600 each -- dealer did give me a 15% discount, so ended up costing $510 each ($1,020 total!). called Toyota of America and they are investigating, but, based upon all of these complaints and my own experience, this is a real safety issue and needs to be corrected by Toyota. I love my Prius recommend it to everyone, but Toyota really needs to address this now.

Driver side headlight shuts off intermittently but stays off until the headlights are turned off and then back on. This is the second time this failure has occurred. The hid bulb was replaced about 6K miles ago. The vehicle now has 41000 miles on it. This is a safety issue which Toyota needs to address quickly.

He stated that the failure was intermittent and is in the process of taking the vehicle to the dealer. The manufacturer will be notified. The failure mileage was 40,000 and current mileage was 100,000.

Headlights fail intermittently - one or both headlights (hid type) will go out without warning. Turning the headlight switch off and then on will fix the problem for some amount of time before the problem recurs.

My 2006 Toyota Prius began experiencing sudden headlight failure after 20,000 miles. I would be driving at night and suddenly both headlights would go out, I would switch them off and on again, and they would come back on. Sometimes I would be driving on city streets, not aware that they had gone off, and other drivers would stop me and tell me that my headlights were off. I would check the switch, see that they were supposed to be on, toggle the switch and they would come on. I took the car to my local Toyota dealer where I have all my maintenance done. After investigating for a few days, they replaced both H.I.D. headlights and corrected the problem. Now, 20,000 miles later, I'm experiencing the same problem. My left headlight suddenly will go out and have to be turned off and then on again to light. This happens every few minutes, most alarmingly on crowded freeways at night. I took the car back to the dealer, and they replaced the left headlight. They didn't charge me for the light because of my previous experience, but I did have to pay the labor fees, since the car is no longer under warranty, but exhibiting the same problems that it did when it was. I'm very concerned that this is going to continue to be a dangerous and costly problem. I don't feel confident that my car is safe to drive at night, because unless you are looking for the problem, headlight failure is something that you might not realize has occurred until it's too late. Also, it doesn't seem reasonable that I'm supposed to replace a very expensive part every 20,000 miles or more to continue to operate my car safely.
