Four problems related to headlight switch have been reported for the 2010 Toyota Prius. The most recently reported issues are listed below.
My Toyota Prius is in good working order, as I just got it inspected for the NY state annual inspection on 3/23/2017. Last night, 4/2/2017, I drove my car to a restaurant and parked it there. When I got back into my car to leave after my meal, I turned on the ignition and switched the headlights to turn on while the car was stationary and parked, but both appeared to have burned out suddenly. Only the running lights switched on. To drive home, I had to use my high beams. I tried turning the car on and off, and switching the headlights on and off while the car was parked, idle and in motion to see if they'd turn back on, but they wouldn't. When I got home, I did some research and it seems that this is a long-standing problem for this model of car, as well as Priuses made in the years prior. . Read more...
I got in my Prius about a month ago and turned the headlight switch on, and neitherof my low beam headlights worked. I thought it seemed odd that both lights went out at the same time. I purchased the most expensive bulbs at my local auto parts store and replace the bulbs. They worked great until about an hour ago. I started my car and when I turned the head lights on, both of them came on for a fraction of a second and then immediately went out. I had to drive home with my bright lights on. I started reading Prius forums and came to realize that hundreds of people with the same Prius model and year were having the same exact symptoms in thier cars. There's obviously an electrical problem with the 2010 Prius. It's time to issue a recall. Now I'm going to have to by another set of bulbs which will cost me another $60. Please help us. It's unfair that 100's of us have to suffer from such a flaw. Thanks.
Three times in the past 12 months I have had my one or the other of my headlights dim and go out. The first time I replaced both headlights assuming the light needed to be replaced so I should just do both. It has occurred two additional times and finally, last night, I returned to my parked car to discover both headlights were out. I was forced to drive home switching between high beams and no lights. Replacing bulbs every few months seems excessive. Losing headlights in the dark is dangerous. This problem needs to be addressed by Toyota and a recall needs to be initiated.
2010 Toyota iv Prius: returning home at night in a dark, rural country area of pennsylvania. Windy, two-lane road with frequent opposing traffic. Left front headlight goes out making it very difficult to see with remaining headlight. Switched to high beams which worked ok until opposing traffic appeared and had to switch back to low beam (singular). A dangerous situation with opposing headlights in your eyes and not enough light from my own car to illuminate the road in front of me. Later, it turned out that the headlamp bulb was ok and "something" was making it either intermittent or go out completely. Sometimes striking the headlight lens assembly with the heel of your hand would get the light to come back on. My wife recently was cited for driving with a headlight out in our local area. This is not a safe situation and the local dealer says he can't help us.
