Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

We were driving on the interstate at 70 mph, when the headlights suddenly went out. It was dark and raining, and were unable to see the road edge. We pushed the emergency flashers and were able to see how close to the road edge we were. About two minutes later, the lights both came back on and we continued to drive to seek a safer area. Every 15 minutes the lights would flicker.

I noticed some condensation in both front headlamps some time ago but just thought it was a cosmetic problem. About three days ago both my headlights went out. I took my car to the dealership and they informed me that the water inside the headlamps caused my hid lights to short out. I am out of the 36 month 36,000 mile warranty, but still within my extended warranty's limits. Toyota is not going to cover the replacement of the light bulbs or change out the headlights since I'm past the original warranty coverage limit. I was quoted by my Toyota dealership over $1,500 to repair this problem. I also found a memo from Toyota (memo # T-sb-0188-11) that talks about this problem and states that under the oem warranty, it should be replaced at no charge to the customer.

When I turned on the car, the headlights would not turn on. Both lights had been fully operational the day before. Both high and low beams on both sides did not work, so it is definitely not the case that four separate bulbs or fuses all blew independently. I tried turning the headlight switch on and off several times, but this did not correct the problem. The fog lights do illuminate, but that is not enough illumination for safe driving in my area.

Both low beams have gone out without any warning, but replacing bulbs and fuses doesn't fix the issue.

The contact owns a 2009 Toyota Prius. The contact stated that water penetrated the headlight's plastic covering due to improper sealing and caused the light bulb to fail. The dealer replaced the light bulb housing but the failure was not corrected. The passenger light bulb failed numerous times. The manufacturer was made aware of the failure. The approximate failure mileage was 90,000 and the current mileage was 100,000.

The headlights have been going out randomly for the last few months but only one at a time. This evening while driving home from a late meeting, both headlights went out while driving at 55mph. I pulled off the highway and tried turning the car off and on again. Headlights went on when I turned the car back on, so I resumed driving only to have the lights go out again! this time I flicked on the high beams and the lights came on. I stopped to grab a bite to eat figuring I could do the high beam trick again. When I started the car, the lights went on and high beams turned on when I engaged the lever. While driving home, less than 2 miles from where I started the car, headlights went out and the high beams did not work either when I attempted to turn them on. I pulled over to turn the car off and on again but with no luck this time. Very slowly drove the last mile home on the less traveled road with my flashers on...this situation is incredibly dangerous.

Headlights go off by themselves. When I start the car both headlights go on, but after driving a little while the left or right, or sometimes both headlights will shut off.

One week after being at the dealership for its routine oil/vehicle check-up (55,000-60,000), my red brake light, the yellow warning sign and the ABS lights come up on my dashboard. Towed it back to dealership since the brakes didn't work. They found I needed to change my brake actuator and the solenoid that is stuck. According to what I've read, this should not happen period paragraph but if it does it would be on a much older vehicle with a lot more miles with a stop and go history. According to the customer service representative at the dealership this is a malfunction of the part. When I called Toyota they gave me the go around about being out of warranty. I need help. Also there is a reflective line of light that shines on the driver side of the window from my dashboard.

While driving at night, the passenger headlamp assembly (every bulb, not just the main high-intensity bulb) went out. Wiggling the connector at the back of the headlamp assembly when the headlamp gets in this condition does not fix the problem. I can get the assembly back in working condition by turning off the lights and turning them back on again. This is dangerous! when the light came back on again, it was slightly flickering at first and now seems dimmer than the driver side light. I have also had connector-related issues on the rear brake lights, where they go out at random times. Turning the lights on and off does not work to get the brake light working again. I have to manually tighten the connector at the back of the brake light assembly to get the light working again.

I have noticed for some time now allot of Toyota Prius cars driving in dark conditions with no headlights on. The tail lights are on but no headlights. This would suggest to me that there is a manual headlight switch or else different parameters for the head and tail lights. As for the reason, I believe to conserve power on the electric batteries. If the driver is in control of the headlights this control should be taken away. It is rare in this day and age for a manual headlamp switch even on the most basic cars, so I believe Toyota was fully aware of what they were doing and what the drivers were likely to do. But yet Toyota made sure they were legally covered with the tail lights. After all if the driver hits a car or pedestrian its the drivers fault but if Toyota Prius cars suddenly start getting rear ended, its Toyota's fault. If the headlamp is not in control of the driver why the difference in timing when they come on? I would suggest again to conserve power and make their cars go farther on electric power at the expense of public safety. I am writing this primarily from a pedestrian point of view because I am a runner and have had a couple of semi close calls because of the headlight issue and one closer call because they are so quiet.

Passenger side headlight goes off intermittently. I noticed it around May 2009, and reported it during my may pre-paid Toyota scheduled maintenance., which was the last one for my plan. Toyota said they found no problem. The incident is noted on my Toyota paperwork.
