car   Headlights problem 1
Failure Date: 01/24/2017

On Jan 24, 2017 while driving this car at night both headlights turned off. When I turned the knob to turn the lights back on only the parking lights came on. The car was in motion on a city street when this happened.

Earlier I reported that both headlights went out simultaneously. My mechanic replaced both headlights and they now work. 37 months ago the same thing happened. It seems highly unlikely that this is just a coincidence. Fortunately the first time it happened I was close to home but this time I was not.

Headlights fail frequently. This happened over a period of 18 months. It began with a front driver-side headlight not working, then both headlights not working - each was replaced when noticed they were not working. The most recent time, 5 months after the last replacement, I noticed one headlight was out again, then, while in park, with the car still on, I turned the lights off then on again, and after that both headlights and one daytime running will not work. Needless to say this is incredibly dangerous.

Failure Date: 12/20/2016

I've had to replace my low beam head lamps 4 times in the past 6 months. First I was on a 2 hour long trip when my passenger and I could specifically see both headlights were getting dim. After about an hour of driving they had both gone out completely and I was forced to use my high beams on the interstate. When we arrived in town, both bulbs were replaced and the driver's side bulb lasted 3 months before dying out. I rode around like that for a week because I kept forgetting until I'd drive at night and the shops were closed. So about a week after my driver's side bulb died, I went to the auto store and bought a new bulb, only to find out my passenger side bulb had gone out that same day; I didn't notice because it was during the day. Thankfully I was already at the auto shop and was able to have two new bulbs installed at the same time. Well. . . With my brand new bulbs I was confident that it was going to be fine this go-around and they were bright for a couple months. Until my driver's side bulb went out unexpectedly when I was parked in my driveway. I was getting ready to leave and saw the reflection on my neighbor's window -- no more driver's side light. I put my plans on hold until I went to the auto shop and they replaced the bulb no problem. Four days later, the passenger side bulb goes out. I'm fed up with having to get new bulbs every few months (or days for that matter). It's occurred when I was parked, driving slow in the city, and going fast on the interstate. It doesn't matter the state in which the vehicle was being handled. The lights are going out consistently and it's occurring far too frequently.

car   Headlights problem 5
Failure Date: 12/12/2016

In 2014 my regular beam headlight went out. The dealers wanted $130 to put in a new bulb saying the bumper had to be removed. My husband bought a bulb at the auto parts store and installed it without removing the bumper. Since then I have replaced several bulbs on both sides and was finally told by sylvania that I need to change both at the same time which I did about a month ago. A couple of nights ago, I started the car and both headlights were out and the fuses were intact. I put in two more bulbs, but I can barely see with them although they are lit. The beam is very weak. The dealers want over $100 to do a diagnostic to find the problem or before they will give me a quote of the cost to remedy the problem as stated by Toyota in a technical bulletin. This was my third Prius, and last one.

car   Headlights problem 6
Failure Date: 11/22/2016

Headlights have burned out 4 times in the past 3 years- both at the same time and previously one burned out within a week of the other.

car   Headlights problem 7
Failure Date: 11/21/2016

Low beam headlights go out at least 2 times a year. I have to replace the low beam bulbs at least twice a year. Wiring seems fine, no damage they just go out randomly throughout the year.

car   Headlights problem 8
Failure Date: 07/27/2016

For the past year, the low beams on my 2010 Prius continue to burn out within a few months of being replaced. I have had to drive twice in the dark with no low beams and had to use my high beams until I was able to get home/buy new bulbs. It doesn't matter what brand or type of bulb I use, they are burning out within 45-60 days of replacement. It's extremely dangerous especially since I spend a majority of my time driving for work. The Toyota dealer I took my vehicle to in may 2016 told me there was no problem, they'd never heard of any problems with the lights, and that I just needed to buy "expensive" bulbs. After installing the most expensive bulbs I could find, both headlights burned out within 60 days. It's very frustrating buying new bulbs every 2 months.

car   Headlights problem 9
Failure Date: 07/02/2016

Low beam headlights failed with less than 10,000 miles since last replacement.

car   Headlights problem 10
Failure Date: 05/14/2016

My headlight caught fire and severely burned my car. I was driving down the road on a city steet and saw a wisp of smoke and pulled over into a store parking lot. I had no warning lights indicating anything was wrong. It began to smoke more, and I cautiously opened the hood to see a fire coming from my drivers side headlight area. Within seconds there was a blaze, and it took 3 fire extinguishers to put it out. The fire department confirmed that the fire originated from the headlight. I had previously experienced problems with my headlight becoming dull and cloudy. An earlier NHTSA investigation did not result in a recall. I think it's the same problem with the headlight, only much worse. If there were not multiple fire extinguishers available the car could have easily exploded before the fire department arrived. It could have easily caused harm to other people.

car   Headlights problem 11
Failure Date: 04/04/2016

Both of my low beam headlights went out suddenly. I didn't realize it until I was driving onto the freeway and had to turn on my high beams so I wouldn't crash while on the dark onramp of the freeway. The housing of the left low beam is blown out. I brought in my Prius to the dealership and they would not cover this even though I have the platinum warranty.

car   Headlights problem 12
Failure Date: 03/18/2016

2010 Toyota Prius headlights burn out frequently. One of the headlights burn out every 5 to 6 months. I can't just replace the burnt out bulb as the other one then burns out.

car   Headlights problem 13
Failure Date: 03/14/2016

One of my headlights went out a couple of months ago, so I replaced both. A few weeks later, I was driving on an interstate highway at night, roughly 8pm, and my both of my headlights went out. They would not come back on. Only the high-beams were functional. After speaking with my local Toyota dealership, this is a known issue of a faulty wiring harness. The local dealership refused to replace the faulty wiring. I find it difficult to comprehend how a car's most basic safety feature, maybe aside from the brakes, is suffering from a known issue and nothing has been done. Without an intervention in this matter, Toyota's willingness to ignore this problem, as they have with many others in the past, will certainly lead to death.

car   Headlights problem 14
Failure Date: 02/06/2016

Headlights stopped working. I got into my car to drive to work and found one bulb out. That night I got into my car to drive home and found the other bulb out. I had to drive home in the rain with no headlights, using my high beams whenever possible. Changed out the bulbs numerous times and nothing came on. When taken to the dealership was told an updated wiring harness was needed and would cost me nearly $800! if the wiring harness needed to be updated, Toyota clearly knew there was an issue causing the headlights to short. I now have a vehicle that I cannot drive safely because I cannot afford to fix Toyota's defective equipment!.

car   Headlights problem 15
Failure Date: 01/26/2016

Headlights have gone off while driving at night. Replacement of the bulbs began in 2013. Only recently while driving at night on the interstate and back roads,did we realize that were sometimes working and this was a reoccurring issue.

Failure Date: 12/28/2015

Headlight out last year. Replaced both. One headlight out this month. Replaced the one with previous year good bulb. Now, both low beams out, only high beams work.

car   Headlights problem 17
Failure Date: 12/02/2015

Headlights continue to burn out. We have changed one or both headlights at least six times since may 2015. This happens unexpectedly, going down the road at night one or both headlights will burn out. When you change them, will last a couple weeks to months. Very scary when going down a two lane back country road at night. Any help would be greatly appreciated.

car   Headlights problem 18
Failure Date: 12/01/2015

Both headlights go out at the same time while driving. First time they just had to be screwed in but now a month later they are both out again. Has there been a recall?.

car   Headlights problem 19
Failure Date: 10/25/2015

Recurring double headlight failure, sometimes intermittently. No warning of failure.

car   Headlights problem 20
Failure Date: 08/26/2015

The low beam head lights constantly burn out. My car is at 108,500 miles, and I have replaced the low beam bulbs at least 5 times in the last 3 years. I have had this occur while driving on the interstate 5. Another driver on the highway flashed lights at me, pulled up next to me, to indicate that my lights were out. I had to drive with the high beams on for over 20 miles. It was a very dangerous situation, because it was blinding to other drivers. However, if I had not done this, I would have been driving with no lights at all. This has happened to me three times after replacing the bulbs, which will last for a while ,but quickly stop working. I have owned several cars and have never had to replace the headlights even once.

car   Headlights problem 21
Failure Date: 08/12/2015

We purchased the car used from a Toyota dealership in spring of 2013. We had never had to replace the headlights until one side had stopped working in may 2015. As we always have done with our vehicles, we went to an auto parts store and bought the correct head lights for our make, year & model. We replaced both of them in may and in August (3 months later), both had gone out with the initial outage having occured while I was using them in the dark on a freeway. Luckily I had brights that still worked but I have since had to replace both lights again and they still remain un-working. I am scheduling repairs, however, this seems to be a major defect either in the electrical engineering or possibly related to fuse shortages. We have made several phone calls to repair shops, other Prius owners, as well as read many safety concern forums regarding this very popular issue even with 2010 models. I understand Toyota seems to take no responsibility for the high-risk headlight failure in Prius models up to 2009 but this seems flat out ridiculous and I should not be required to return home before dark or be forced to drive with my brights while oncoming traffic flashes at me as if I'm being inconsiderate.

Failure Date: 08/01/2015

Tl-the contact owns a 2010 Toyota Prius. The contact stated that while driving at night approximately 55 mph the visibility started to deem, when the contact got home noticed that the passenger side low beam headlight was out, two days after the driver side low beam went out also. The vehicle light bulbs were replaced by the owner. The contact also stated having to change the low beam headlight bulbs four times. The vehicle was never taken to the dealer or an independent mechanic to get a diagnosis. The manufacturer was notified of the failure. The approximate failure mileage was 99,000. Bp.

Failure Date: 07/19/2015

I was driving home from havenlock, nc on us 70, us 258, us 58 and us 264. I noticed that my low beam headlights were very dim making it very hard to see road marking or signs. There is a stretch of us 58 where they are repaving and they are no road marking at all and I could not see where my lane (2 way traffic). I considered this a very serious problem that the headlight are dim and could have led to a very serious accident. I have noticed that others have complained about the same problem with the Prius 2010. Not able to see more than 30 feet ahead on a very dark night is very scary and had me shaking.

car   Headlights problem 24
Failure Date: 04/24/2015

I purchased the Toyota certified pre-owned Prius in July 2013. I first had an issue with the headlight in August 2014 when the headlight kept coming loose from it's casing. This happened again on April 24, 2015 only this time the headlight fell to rest on some plastic and caused the headlight assembly to start on fire. No one was injured. I used a fire extinguisher to put out the fire. I believe the socket part of the headlight assembly was defective.

Failure Date: 04/24/2015

Since owning the vehicle, I have experienced the low beam headlights burn out withing 9 months. Recently, one bulb burned out within 3 months. I was pulled over by the city police, driving with one headlight out is not only a safety issue, but could result in a citation.
