car   Headlights problem 2
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: 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 5
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.

car   Headlights problem 6
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.

Failure Date: 02/27/2015

On February 27, 2015, our house burned in the middle of the night while we were asleep. The fire started in the near vicinity of the right front headlight of the 2010 Toyota Prius. The car had been serviced just before the fire on February 25, 2015 at the local Toyota dealership. The car was off at the time and the key was not in the car at the time of the fire. While we were sleeping, the car evidently caught fire spontaneously at approximately 2 a. M. While it was parked in the garage. The garage door was closed. By the time we woke up, the garage was fully engulfed in flames. We were able to escape the fire. However, our house was too severely damaged (fire, smoke and water) after the fire to be livable, and it is currently being rebuilt. Our family of four (husband, wife and two children, 15 and almost 11 years old) is currently living in a rental house. We lost all three of our cars (the other cars were a Dodge durango and a Honda accord) and a majority of our possessions. Damages are estimated to be likely in excess of $500,000 including house, cars, damage to landscaping, personal property, furniture, clothing, etc. Our homeowner's insurance is seeking a subrogation claim against Toyota for the expenses incurred regarding our claim. The Prius is scheduled to have a deconstructive exam soon with multiple parties present and is currently being held as evidence.

car   Headlights problem 8
Failure Date: 02/04/2015

I recently replaced one of the low beam headlights, only to discover a few weeks later that both of the low beams had burned out. I've never had two headlights burn out at the same time! tonight I discovered that another of the low beams has burned out. That means that this bulb burned out in less than two months and only about 1000 miles. I am afraid to use my headlights during the daytime for fear that they will burn out and not be available when I need them to see again at night. This must be a wiring/configuration defect! please do something about this!.

car   Headlights problem 10
Failure Date: 01/18/2015

Low beam headlights stopped working during night driving. Had to drive home with high beams only at night. Felt endangered and very unsafe both for myself and the public.

car   Headlights problem 11
Failure Date: 01/17/2015

After returning to vehicle, low beam headlights failed to properly illuminate. I replaced both bulbs with new ones, and they still fail to cast enough light. The bulbs appear to be on, but are too dim to be effective.

Failure Date: 01/13/2015

I was driving back home from work on a country road at night when my low beam lights both went out. I had to drive home with my high beams on. This is the 4th set of headlights in a year that we have replaced.

car   Headlights problem 13
Failure Date: 11/10/2014

Passenger low beam headlight went out first then a few months later the driver low beam headlight went out and has now gone out for the 3rd time. Had to use high beams all the way home cause I could hardly see anything with low beams. Have been pulled over a few times by the cops for this problem. Pulled over 2 times in just one night because of this problem.

car   Headlights problem 14
Failure Date: 10/25/2014

I do not have the need to do much night driving. Last Saturday, while returning from a family visit, night had approached. The dim lights were next to worthless. The cars approaching me from behind lit my path. I had visited Toyota a few weeks back and they advised me the headlight bulb was loose. I tightened it, but that night, the illumination of the headlights was lacking. I returned to Toyota today and they tell me these headlights have a "projector" that is bad. . . Both sides! there is no recall or manufacturer's defect that covers the replacement. They will gladly replace these for $852. 00. I have regarded Toyota as a top contender in car manufacturing. I am terribly disappointed and appalled that this safety issue is not covered by Toyota.

car   Headlights problem 15
Failure Date: 08/25/2014

I purchased the car new in 2010. About a year ago, the headlight bulbs started burning out repeatedly, as well as the marker bulbs and the license plate bulbs. The last incident was chilling. I returned from a trip, got off the plane, picked up my car at airport parking, turned on the headlights and they were both out. I had to drive 45 miles home at 10 pm either without headlights or with my brights on. It was terrifying. The bulbs had been replaced within the previous 6 months. This is a serious defect that NHTSA and Toyota must address. I have friends who are having similar problems. Additionally, the headlight casings are marred, which diminishes visibility. Toyota clearly has used defective parts to encase the headlights. Again, my friends with Priuses have the same issue.

car   Headlights problem 16
Failure Date: 07/01/2014

Low beam headlights both went out at the same time while driving down the road. The driver's side has since been replaced twice over the last 6 months and is now out again and the passenger side has been replaced twice.

car   Headlights problem 17
Failure Date: 05/02/2014

One of the headlights (low beam) stopped working sometimes in 2013, then it came back. Over the course of 2013-2014, the front right light went out and I had the light bulb replaced. Then it died again. I replaced both bulbs based on the aftermarket recommendation but the lights are not bright enough. The front left parking light also died twice. Something is screwy with the electrical for the lights.

(40) fleet 2010 Toyota Prius. Consumer writes in regards to vehicles headlights malfunction. The consumer stated he had to routinely replace 7-8 headlamps per week on the fleet of 40 vehicles. The dealer informed the consumer the frequent burnout of the bulbs was likely due to wither security officers not properly caring for the vehicle or the vehicles being used more frequently for personal use. Also, the wiring harness failed on the vehicles. The consumer stated there is currently 1 vehicle in the shop now, and the dealer quoted a price of $8,000. 00 to replace the wiring harness.

My daughter was driving hone from work and got on the freeway early Monday morning approximately 1:05 am and suddenly the headlights went out. She tried turning them back on and off and on again but still no lights, so she had to drive home in the dark with no head lights. She was almost hit by other drivers because they could not see her. It was a scary ordeal for her and my headlights are still not working. I just purchased this vehicle on December 10, 2013.

car   Headlights problem 22
Failure Date: 02/26/2014

I purchased a certified used 2010 Toyota Prius from the east coast¿s number one certified used Toyota dealer. I was presented with papers showing all the checks performed with a certified used Toyota and that the vehicle I was purchasing had pass all the inspections. I test drove the vehicle during the day and did not use the headlights. Once I was home (over 3 hours away) I used the headlights for the first time in the next few days. The driver¿s side lights were very dim. I took the low beam bulb out and notice a lot of corrosion on the bulb and moisture in the headlamp assembly. I let it dry out and replaced both the drivers and passenger side low beam light bulbs. Over the summer I noticed a few time moisture would build up but would be gone within a few days. Now during the winter the moisture has frozen inside the driver side headlamp assembly and impedes on the effectiveness of the headlamp. My visibility is reduced and has now become a safety issue. I have not owned the vehicle for a full year yet and even purchased the top of the line extended Toyota warranty. My local dealer stated it was not covered under any warranty and that would cost around $500 to be replaced. Toyota has a technical service bulletin on this issue and should repair at no cost to owners due to a safety hazard.

The headlights burn out on a regular basis. Shortly after replacing the bulb it will burn out again (usually within a week). At times both sides burn out at the same time without warning causing a safety hazard. This is a known problem for Toyota Prius products. We have contacted the company who states this problem was resolved with the 09 model year and refuse to admit or assist with repairs of the known electrical defect.

After leaving a skating event with 4 kids in my car at approximately 8:30 pm, I noticed that I had no headlights which had worked 2 1/2 hours prior. Both lights went out at the same time. All other lights worked, including high beams which I used to continue driving that evening. I called the local Toyota dealer who informed me that "this was a common problem in the 2010 Prius. I made the appointment to take my car in for repair and was informed that it would be $800 to fix the problem since my car was out of warranty. When I dropped my car off, the service rep showed me a spec sheet stating that I needed a "headlamp durability enhancement" (spec sheet was issued oct 2012) and stated that the problem was "low beam headlamp bulb lifetime was shorter than customer expectation". That wasn't the problem, the problem was that both lights went out at the same time which is a safety issue. I requested to have the old parts returned and an experienced friend went with me to question why I was charged for joints when none had not been taken off my car. I was told that this was not on my car previously and that I could review a technical service bulleting (TSB-0204-12) on the Toyota website which I cannot locate this document anywhere online. A formal recall for this problem was never issued even though Toyota knew that this was a recurring problem in the 2010 Prius model.
