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.

Pulled over 2 times in just one night because of this problem.

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.

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.

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.

Failure Date: 02/03/2014

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.

Last night, at 10 pm, on getting back to into my car to drive to my house 7 miles away, both the headlights did not work. The high beam lights were working, but the regular headlights did not. As a result, I was driving in dark on a single lane highway, and it was a very scary experience.

Failure Date: 08/03/2013

While on vacation on Aug 3, 2013, we were driving in the smoky mountains in gatlinburg, TN, via the scenic loop down from cades cove. I was driving and my husband, our 13 year old son (only child) and his 13 yr. Old buddy (my friend's only child) were the passengers. The route was a steep mountainside with typical winding mountain roads, pitch dark at ~8:30 pm. Suddenly, both headlights went out, together, at the same time. The dashboard showed that the headlights were on, no warning signs came on. I had driven through a tunnel a bit earlier and the headlights were both working. Panicked, I pulled over at the next lookout ledge, turned the car's power off and on several times, turned the lights off and on several times while the car was running - nothing. No cellphone service was available in the area. As I was hysterical and terrified beyond my wits, my husband took over driving duty and drove with the emergency flashers on. After a few miles of sheer panic and incoherence, it occurred to us to try the high beam, which fortunately worked and we are alive to tell the story today. As soon as we got cellphone signal we left messages for our friends in case we died they would know why. Get a grip, Toyota! I loved my Prius - this is my 2nd Prius, but I am now petrified to step in this car again. I found thousands of similar complaints online regarding both the Prius headlights failing at once, so Toyota you know I am not an isolated case. Horrible, dangerous problem with the 2010 Prius, you are risking lives!.

My commute is 62 miles, one way. Tonight I realized my low beam headlights were not working. My high beams work. I drove the 62 miles with my high beams on. The fuses were fine. It is odd that both low beam lights were out at the same time but the high beams were fine. I searched online some and there were numerous similar problems with the Prius low beam lights.

There is a chronic problem with the headlights on this car. They continually burn out, or, go out and than come back on when headlight is 'tapped' lightly. Dealer and independent repair shop(s) have replaced numerous times and problem reoccurs.
