Electronic door locks continue to fail. I have taken my Prius back to Toyota two or three times to fix broken electronic door locks. At that time, vehicle was under extended warranty and the cost to replace the electronic door lock was covered. Vehicle is no longer under warranty and Toyota is quoting over $400 to fix. The fact that this continues to happen (and to different doors) leads me to believe there is a known defect in the electronic lock mechanism. I do see a few other complains of the same issue. This represents a real safety concern as the affected door remains unlocked while driving and can be opened while vehicle is in motion (such as by a child). This is also a theft concern as the door does not lock unless walking around to the affected door to manually lock it.

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.

On May 30, 2015, our home burned to the ground. The firefighters are certain the cause of the fire was my 2010 Prius - they know the fire started in the rear of the garage, the only other item in that area was a bicycle. Arson, faulty wiring and accidents were ruled out. Investigations continue, but they have identified an arc between the battery and the relay switch. My homeowners insurance carrier (erie) is trying to decide whether they should expend the additional $1,500 to open the relay switch box to see if they can determine if the arc was the cause of the fire, or a result. From the video footage, it is obvious that the water being poured onto the garage increased the intensity of the fire, which was due to the magnesium battery. Thestarpress.com has all the video: www.thestarpress.com/videos/news/2015/06/03/28436619/ we were trapped in an upstairs bedroom for 40 minutes - and given up for dead before the 911 operators heard my labored breathing over the still-open phone line. A heroic firefighter threw himself through the wall of our second-story bedroom to rescue us. My husband was not breathing when he was removed from home, but we have both recovered. We had been out to dinner earlier in the evening, but the car had been parked in our garage for several hours. I have heard of many other Prius fires, and wanted to alert you to our experience.

Both headlights (low beam) go out at the same time. No apparent issue with the fuses. Replacement bulbs experience a shorter than expected (approx. 6 weeks) life before burning out again.

My cars low beam headlights fail quite often; sometimes lasting less than two weeks. At other times, the bulbs put out very little light. The failures most often happen when the lights are first turned on, or when switching between high and low beam.

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.

The contact owns a 2010 Toyota Prius. The contact stated that the low beams failed to illuminate properly. Additionally, the low beams lights failed to function when driving. The contact had to apply the high beams when the failure randomly recurred. The vehicle was taken to the dealer who replaced the driver and passenger side low beams but the failure recurred three year after the repairs. The contact replaced three lights on the driver and two on the passenger side for the low beams but the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 75,000.

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.

The vehicle runs ok and a few minutes later the yellow triangle turns on, as well as the check engine light and the vehicle starts to lose power. After a few more minutes the red steering wheel light comes on along with the "check hybrid system" message and the rest of the lights and the vehicles loses all power and stops. It will normally turn back on but there was one occasion where it didn't and my husband had to push the car to a parking lot. I took the car in on the recall which should cover this but all they did was update the software and blame the issue on a car accident. I don't know if this is true as just purchased the vehicle but it sounds to me that they could have fixed the issue under the recall.

As many previous owners described, I am also having problems with the brakes at low speed since the beginning of owning this vehicle (October 2009). Dealer couldn't replicate the problem. Although the car went through the recall for the break system is still having the same issue ever since. The other issue with the brakes happens after rain. It makes a screeching noise without performance being effected. It goes away usually within a half an hour. This has been an ongoing thing too for few years by now. The other issue I had as well as others is dimming of lights that has been occurring since last year. We needed to switch the lightbulbs more frequently than seems normal. Didn't even think it was out of the ordinary until I read the comments here about it. The other problem I started to have is with a stereo display system and the voice activation for the bluetooth. The display had some weird lines on it after a very cold or a very hot day (radio was working fine just the display was not working properly). Eventually goes back to normal but this started happening the last year or so. The same time also had a problem with the voice activation unit which turned on unexpectedly and turned back on in 10 seconds after each time I turned it off. This was happening for a good 30 min at that time. This only occurred twice but both times was after a hot day last summer. This year so far haven't happened yet.

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.

When flashing the low beams/high beams on/off I routinely blow the low beam bulbs. Not both at the same time but eventually both will blow. I understand from reading forums that this is a known problem however Toyota will not address it unless you are under the 36K warranty. This should be a mandatory recall.

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!
