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.

Prius 4-cyl

  • miles


While driving, the headlights to my 2007 Prius go out. At first this happened only to the left headlight, then a few months and many miles later, both headlights go out while driving. So, as I am driving either the left headlight, right headlight, or both will go off unpredictably and sporadically. I have been driving like this for about 15K to 20K miles.if the problem was the light bulb, as the dealer told me, I think it would have gone completely out by now. From what I have read it sounds like the lighting system is faulty in some way.however, Toyota Corp is not taking responsibility for this issue. When my lights first went out, I knew immediately I needed to turn the light switch to the "off" position, and then back to the "on" position to get the lights back on. I knew this because when Toyota sent out information on the floor mat and accelerator defect (witch led to a recall on the accelerator pedal) they also sent out information on the headlight defect. Where is the headlight recall?! in these information sheets Toyota laid out directions on what to do if your accelerator pedal got stuck, as well as what to do if you lights "happened" to just shut off. So when a notice like that comes out, I assumed this meant Toyota would fix the problem on the house. So, when I had this problem, and went in to the dealer for my oil change, I mentioned it, and said I would like to have the issue fixed. I did not expect to get a quote and be charged to fix Toyota's quality control issue.

About 2 months ago the headlight on the passenger side would go off, but if you turned the lights off and then back on, the headlight would shine again. It was an intermittent occurrence, but now it is happening more frequently and I'm afraid that my wife, since she drives the Prius, may end up in an accident. I've done research on the internet and it seems as though this is happening to many other people.

Hid headlamps on 2007 Toyota Prius dim and then go out. This happens everytime the lights are used. One headlamp has been replaced at the cost of over $200 and now the other headlamp exhibits the same behavior.

  • 60,000 miles
The hid head lamps on my vehicle flicker and go out. If I switch the lights off and on again they light back up. This happens intermittently and randomly. It has happened several times while driving on the highway at speeds in excess of 70mph at night and I feel unsafe. Toyota has refused to accept this is a safety problem, but it is a very common issue with this generation Prius.

2007 Toyota Prius with hid headlights. Headlights will continuously go completely off while driving and require that the headlights to be switched off and on to turn them back on. This will occur intermittently anywhere from every few minutes to perhaps a half an hour or more. The bulbs appear to be in good working condition once they are on but then will go completely dark until you cycle the switch on/off. Literally thousands of owners of these vehicles have reported this same problem. These lamps are very expensive and are supposed to last much longer that regular headlamps, but it appears that Toyota has again failed to adequately test these systems to assure that they are reliable. When the lights go out while driving at night you are left with no visibility at all, a definite safety issue. This has been going on since at least 2006 with no action taken by the NHTSA. Why don't you guys do your job and require that these companies fix these obvious safety related issues caused by faulty parts or engineering!

Intermittent right hid headlamp. Problem started about 40K miles. The light dims, flickers and goes out. Turning lights off to on will fix issue temporarily. Same problem reported by thousands. Repair costs vary from $300 to $2000. The problem occurs daily. Each time there is a risk of being in accident. Toyota and NHTSA are aware of the problem but nothing being done about it.

Passenger headlight works intermittently. Will turn off while driving and occasionally come back on if the lights are turned off then back on again. Dangerous to drive with one headlight working and I can't imagine what would happen if driving and both went out. Does not appear to be a loose connection as turning the lights off and back on will occasionally fix the problem until it happens again.

Prius 4-cyl

  • 85,000 miles
I have a 2007 Toyota Prius with about 85,000 miles and the passenger side headlight only works periodically. Sometimes it doesn't come on and sometimes it works for the entire trip. I do not know when it is working and not since there is no alarm or light indicating that I have a problem. The dealership wants me to replace both hid lightbulbs for $300. I am not sure that this will fix the problem since sometimes it does work and stays on for a long period. This could be a major problem, especially if both headlights start having the same problem at the same time.

Toyota motors sent me a letter saying they installed faulty headlight bulbs in the 2007 Prius and they would only charge me $389.65 to replace them and you can't replace 1 bulb, you have to replace both. This is a safety item that they admit was their problem and I have to pay to fix it? talking to other owners and all of have traffic tickets that Toyota could pay for also.

2007 Toyota Prius is experiencing intermittent hid headlight failure. Right headlight was replaced in 2009 and now left headlight is experiencing same problem. Problem with left headlight began about 3 months ago and now light stays off for much longer and is quicker to occur. Car is at 52K so warranty does not cover this replacement.

Vehicle hid headlights just stopped functioning, they are still intermittent at this time, with the problem getting worse by the week. By shutting the car off, they may be turned on again, but only for a (variably) short time, sometimes less than 2 minutes, sometimes more than 15...

Driver-side headlight functions intermittently at startup....I have to turn switch off completely and turn on, and light functions....many Prius owners have complained about this over the years, and Toyota has done nothing....some theorize the circuit board controlling the hid lights is in a poor location and overheats/defective....anyway this is not a bulb problem, but a system problem.....please help us......

The contact owns a 2007 Toyota Prius. While driving at any speed, the contact stated that the headlights on the vehicle would shut off without warning. He would then turn the switch off and on and they would come back on intermittently but would shut off again. Both the dealer and manufacture were notified who denied that there was a problem. The vehicle was not diagnosed or repaired. The current mileage was approximately 110,000. The failure mileage was approximately 30,000. The VIN was unavailable.

Prius 4-cyl

  • 37,750 miles
While the car is in operation and the headlights are switched on, the driver side or passenger side headlight illumination would intermittently fail without warning. This has occurred for the past couple thousand miles. The current mileage of the car is 39,750. The lights would function again after switching them off and back on. This happens at least once a day and has progressively been worse. Safety is a key issue here in that if both lights fail while driving at night, could seriously cause a crash or accident. An online search for other drivers of the same make and model have revealed similar incidences/experiences. I proceeded to first call the manufacturer of the vehicle to see what can be done since the vehicle is barely out of warranty range and I have noticed other drivers online have received repairs and/or parts at no-cost to them for the same incident. They wanted me to bring the car into the dealer and get a diagnosis to determine if they can reimburse me for the repairs. The dealer reports that I need two new hid (high intensity discharge) bulbs and the total cost for the repairs would be approximately $600. I had no choice but to proceed with the repairs because my safety is at stake. I called back the manufacturer, as instructed, and without even considering review of the findings of the diagnosis performed by the dealer, I was told that the repairs would not be covered at all. I proceeded to ask why some drivers reported online that their repairs were covered outside of warranty and mine would not be. I simply wanted to know the criteria for choosing who gets to have them replaced for free and who would have to pay for repairs. I was told that to their knowledge, nobody has received full reimbursement for their repairs, only a reimbursement for the difference in the cost of the bulbs (which was reduced from $300 to $150/each). Had I been told this before, I would not bring the vehicle in for a "diagnosis" for a problem I knew already.

I've got 2007 Prius. One of the headlights keeps going out. I can't really tell when or how it goes out since I can't see it. I'll notice it when I see the reflection in the back of another car. If I turn the bright lights on and off it has no effect, but when I turn them all the way off and back on the light comes back. Sometimes on long trips it will stay on the whole time, sometimes it won't. sometimes on short trips it will go out, sometimes it won't.
