The headlight bulbs keep going out. I have replaced the bulbs at least 2-3 times a year for the past few years. I have asked dealers about this and they tell me there is no recall or TSB. This is a hazard to night driving because of decreased illumination, especially in dark roads with not enough lighting. Please recall/fix this issue!!.
My vehicle has an ongoing issue with the headlights not being bright enough to drive at night with. I have replaced the headlights more than 5 times now over the course of a year, each time with different brands including Toyota oem headlights. Each time, they are still not sufficiently bright enough to see with at night. This has led to 3 collisions with curbs and objects which caused damage to my vehicle, because I could not see the objects while having to drive at night. I have brought the issue up to Toyota and they said they would not do anything about it. I brought it in for service to Toyota and they tried to charge me $200 to even look at it, money which I do not have. I am forced to continue driving at night for work and fear I will get into a more serious crash or hit a pedestrian as the headlights aren't bright enough to see safely at night. The photo I have included shows a gash in the tire and dent in the rim where it hit the curb. The issue seems to be the headlight wiring or connectors. When I replace the headlight bulbs, they are a bit brighter initially. Thus initial brightness only lasts about a week, and it's still not sufficiently bright to drive safely. They then dim even further to the point where it's like driving without headlights at all. Again this has led to 3 collisions at this point since I'm required to drive at night and don't have the money to fix it. Toyota refused a good faith repair and did not acknowledge there was an issue, however if you do a web search for "prius headlights too dim" it seems to be a major issue with many other Prius owners. It should be noted that even the high beam headlights are not bright enough to sufficiently see with at night.
The incident was body and light.
Headlamp has gone out 3 times, marker light 2 times. Existing recall on previous year Prius should be extended to 2015 models.
Auto adjusting low beams not working. Low beam is fixed down as if there was a heavy weight load, with no load in the auto the low beam light patern is only 25 feet, this distance puts the driver at risk being unable clearly see the road and drive at a reduce speed or over driving the light. Driver eyes are strained as they try to navigate. There is no problem with the high beams. Affects only at night on highways and. Poorly light wiedy country roads.
