A few yrs ago my headlights stopped working right. They could usually be turned on, but it was anyone's guess how long would stay on. Might be one or both that would suddenly go dark ((a problem since most of my commuting is After dark. Sometimes the light would come back on if I flicked it on and off, sometimes not. Sometimes they would begin bright, then quickly fade to a level that made the car visible to others but didn't illuminate the road usefully. I was pulled over a couple of times when they happened to go dark in sight of a patrol ca.r.

The dealer said the entire headlight assembly would need to be replaced, not just a bulb. After learning that they wanted hundreds of dollars for each, I went online and found dozens of similar situations. Learned that it was possible to buy just the bulbs from Amazon for about $50. YouTube had several videos showing how bulbs could be replaced in 5 minutes, as long as you could work by touch. Eventually had my trusty local mechanic do it while replacing the breaks. Charged me $50 to do it. About 18 months ago, and working flawlessly since then.

For several years now, the passenger side headlight has flicked off after anywhere from a few seconds of driving to several minutes. I just turn the lights on and off and they are on again. Have asked 3 mechanics about fixing it; all told me it would be really expensive to figure out what was wrong with it and I should wait until the bulb burns out. The bulb has not burned out, but the flickering is getting worse and now it is happening on the driver's side. If I report this as a complaint each time it happens, I will post a complaint daily. After reading what is on the web about this, I am going to take it to a Toyota dealer and ask if Toyota will pay for the repair before going to the expense of getting it fixed.

Prius 3.2L

One night I was driving home and an officer's lights went on pulling me over. He brought it to my attention that my drivers side lights were out...both high beam and low beam. The next day the lights worked for a little while and then the same thing occurred they went out. I have brought my car to our local mechanic 2X and found out that a replacement part would cost me $100. For a bulb! From all that I have read it appears likely that this will occur again. My mechanic said that the overall headlight does not appear to be made of quality. I am very disappointed in Toyota for not standing behind their products!

I have had numerous people tell me I have a headlight out. When I look at it, they are not out. I went to an auto supply stor (Napa) where the clerk told me this was an issue with these cars and that it would not do any good to have the light changed, because when he tested it, it was fine. I later had the light replaced at the dealer. Now I am having the issue again. Looking online it appears this is a common problem that can be very costly with no real resolution.

Again I had to replace the right and left headlights on my 2006 Toyota Prius. Not happy with spending money every month now this problem. Toyota needs to do something.

The headlights both right and left work sometimes. They go out when my 17 year old daughter is driving, especially at night, which is not safe. I've changed the bulbs 3 times in 3 months. It's very expensive and I'm afraid something serious can happen if Toyota doesn't address and fix this issue.

I took my car into the Toyota Dealership a couple of years ago to have the lights fixed and they supposedly fixed them. Now the lights are going out again while I'm driving. I've already received a warning from the state trooper next I'll end up with a ticket or worse, an accident.

Prius Hybrid 76-Hp, 1.5L-Liter I-4

  • Automatic transmission
  • 75,000 miles

I got my 2006 Prius at the dealer. The car was under warranty. The problem with the head light started a few months after having the car. Right side head light would go off every so often, but after turning the car off and back on the light would come back up. The 12V battery had to be replaced last summer, and while there (at the dealer) getting taken care of, I mentioned the problem, but because it could not be replicated, nothing got done.

Got pulled over once by the police, but was not given a ticket because luckily, I was able to I turn the car off and back on and the light came on!

Now the car is out of warranty and the entire right side, both lights are off. Checked online and there are lawsuits and all kinds of complains about this issue. It is a know issue, that the dealership did not disclose to me at the time of the purchase of the car. And this issue has been know for years now! I got the car in 2014. The law suits and complaints date back to 2011!!

I bought the car used from a Toyota dealer after it had gone through the shop for 3 days. The problem occurred within the first hour of driving after I purchased it. I went to the service department, and the person greeting me thought I had the standard Halogen bulbs, and told me the bulb would be about $37 and no charge to install. When I came back he told me he hadn't realized I had HID bulbs, and a single bulb would be $300!!!! I was aghast. Fortunately, I went back to the salesperson who sold me the car and he had the service department replace the bulb. I only hope this is not a recurring problem. Those bulbs are ridiculously expensive. I bought the Prius because of the supposedly low cost of ownership. This does not bode well for the future. If there are more issues like this I will buy a Honda next time.

Took car to Toyota dealer, thought headlight had went out. They told me it was a short and I had to bring it in when it was happening before they could do anything. I've took it to a place close by where I live and they told me the same thing. I have a car that I can only drive to the doctors. Can't be driven at dark (have got stopped by police and given warning ticket} and can't be driven when raining. Have had to cancel two doctor appointments this week. As far as I know both lights haven't went out at same time but it changes from right to left light at will

I'm a 68 year old disabled woman and I need my car. I can't afford tickets for driving with only one headlight. I just found out that I'm not the only one having this problem.

The Toyota dealer didn't say anything about there being trouble with the lights just that they couldn't do anything unless it was happening when I took it in. What can I do to get this fixed. It is a danger to myself or others if both go out at same time. What good is a car that can only be driven during daylight hours or when it's not raining. My driving has been restricted for over a year now.

I purchased my Certified Used 2006 Prius in Feb 2011 from a Toyota dealership in Lodi CA. I'm not sure when I first noticed that the left headlight was out but it was sometime in 2013. But it wasn't out all the time. It was out sporadically. I was pulled over by CHP in Aug 2013 and warned to get it fixed. But, since it was a sporadic problem, I put it at the bottom of my priority list figuring it was going to cost me more than I wanted to spend. Then in Spring 2014 while driving at night South on the 99 from Yuba City to Sacramento, both headlights suddenly went out! It was pitch black! I couldn't see the road! I slowed to a stop, switched my headlights on and off a couple times and they were back on again. This happened one more time a couple months afterwards. I keep meaning to ask the Toyota service department to check out the problem, but haven't yet. Again, it's a sporadic problem.

I am getting really tired of people I know telling me "your headlight is out". Then I switch them off and on again until it works.

Finally a friend told me to go online and research Toyota Prius electrical/light problems and VOILA!

It's NOT just ME!

According to dozens of other Prius owners, Toyota is uncooperative, mechanics cannot seem to duplicate the problem, replacing bulbs is not a solution, and many people are driving with defective headlamps which can and do go out at random times and can cause accidents and death.

I've responded to many recalls on the 4 Toyotas I've owned since 1998, why is there not one for this seriously dangerous headlamp issue?

I have had several problems with Prius Headlights. The first time, a couple of years ago, both lights went out at the same time. Service told me that both just went out & would costs over $300 to replace each. After much discussion he replaced for costs of labor. Within 2 weeks I received a recall notice and had to submit my invoice for reimbursement.

Now they now have condensation build up and only work sporadically. I have read numerous articles about problems with the Prius headlights and am now being told it will costs approximately $1000 to have them replaced. Why hasn't there been a recall of these obviously defective lights?

Passenger side headlight goes out regularly. Flipping lights off and on temporarily fixes problem. Sometimes both lights appear to dim to day running lights setting, on a couple of occasions both lights go off. Dealer could not replicate problem said to return when problem gets worse or occurs more often. It is happening more often so will check at next oil change but it appears to be a fairly common problem...without an adequate solution.

All I can say is this is the most frustrating problem I have ever had with any car in my entire lifetime. Cannot seem to fix left headlight. Removed headlight which is absolutely a ridiculous procedure in itself. Found water inside, and the ballast was all corroded indicating the lamp had been leaking for some time. checked lamp by putting in the right side, and it worked there ( also a pain in the ass). I ordered head lamp assy.on line, and it was wrong type, so had to return with penalties I decided to order the damaged ballast and fix my damaged headlight by siliconeing the leaky lens. The new ballast had too short of a wire lead to the lamp so had to extend it to make it work. It didn't fix the problem however, so I am back to where I started..Yes,I checked fuses. Frustrated and refuse to pay for a new headlight at a price of over $600.00 dollars. I am out of breath!!!---Jim Noel

As I was driving my 2006 Toyota Prius at night, I noticed the road seemed "dim" on the right side. I turned the lights OFF then back ON and it was brighter. Later I noticed the same thing and pulled off the road to find the right headlight was not on, but it came back on after turning the switch off and on again. This has happened SEVERAL times over the past couple of months, sometimes affecting the left headlight as well. Once, last month, as I was driving down the highway, BOTH headlights turned off! Fortunately I was able to quickly flip the headlight switch off and on to remedy the situation. The headlight bulbs have been checked and do not seem to be the problem. HELP!

I've mentioned the problem while taking the car in for a check-up, oil change etc. They reported they could not reproduce the problem and did not do anything. It got worse after that but since I don't drive much at night I waited it out.
