Passenger-side high intensity headlight started intermittently failing. The light goes out randomly and unexpectedly. Turning both headlights off and back on again temporarily fixes the issue.

After taking the vehicle in for a recall for a steering column issue, 3 of the buttons on the steering column fail to operate once the recall repair was complete. The dealer says it's an issue with the clockspring cable and are not willing to repair it at no cost.

After short period of servicing a recall on steering extension shaft #C0T, some of steering wheel buttons stopped functioning due to damages to clock-spring cable. The dealership don't want to admit their technician fault failing to realign the steering wheel to center position. Many of Prius second generation hybrid owners been recalled have this issue after fixing the shaft. Is the damaged spring cables already were or due to lack of expertise?

Both headlights went out without warning. This has recurred numerous times since then, also with taillights. I've been pulled over 4 times by police for lights out. Next day, they're fine, or a different light is out.very dangerous and scary, as we live in a rural area with windy roads and no street lights.

Both front head lamps shutoff at the same time while moving at about 25 mph. Turning off the head lamp switch and turning the switch back on restored the lights.

The plastic weld process or other type of gluing process used to make the vehicles exterior front and rear turn signal, brake and back up light lense assemblies or housings fails. All four, two front and two rear, exterior combination light lense assemblies suffer this premature and serious failure. When these exterior lenses begin to fail they allow water intrusion from the exterior of the vehicle. This allows moisture to penetrate into areas of the lense assembly which support all of the light bulbs used to warn or signal other drivers or pedestrians. At a very minimum this problem results in premature bulb failure for all of the signaling systems specified above. Researching your site this problem has been reported to you many times and Toyota motor Corp. Is also aware of this problem. What you don't seem to be aware of is the most serious concern resulting from this problem; if the right (passenger side) rear lense suffers this problem and begins leaking, the water runs or drains directly into the interior 12vdc starter battery well. This battery well is as deep, or deeper than the factory installed 12vdc starter battery is tall and can result in water overtopping the battery. This causes shorting/grounding across the positive/negative 12vdc starter battery terminals. This prevents the operator from starting the vehicle and cuts off power to all 12vdc electrical systems including emergency flashers. It could easily result in serious damage to the 12vdc starter battery and many expensive 12vdc electronic components or systems. This problem is more serious in areas that receive high amounts of rainfall. I called a Toyota authorized dealership, lum's auto center, and reported my car wouldn't start. They suggested I bring it in. After 4 days they were unable to find the problem. No diagnostic codes were logged. This is a serious problem needing immediate attention!

Since two years old the headlights have occasionally flickered, and the pass. Side has gone out. Turning them off momentarily and back on solved the problem. Lately it's gotten worse, and I finally had my mechanic replace the pass. Side bulb. The new bulb ($85) was worse and now I'm told the "ballast" needs replacement for hundreds of dollars. Of course the safety issue at night is primary, but Toyota was derelict in their duty not to advise customers of this highly unusual, potential cost when selling me the car. I've never paid more than $15 for a headlight and have always replaced them myself. Also, the owners manual suggests an easy replacement. My mechanic had to partially remove the headlight assembly. That was another misrepresentation.

The dash board did not display when I turned on my car. Only the blinkers, and air bag lights work on the dash. The gas gauge and the speedodometer do not show, it is black. And my car will not turn off. It seams to me that this issue is a major safety issue.

The following described incidents have taken place at least three times with no warning. Upon starting the vehicle there is no instrument panel display which is digital. The vehicle could still be driven. The vehicle's engine would not turn off without making numerous attempts.this has sometimes taken up to 10 min.. then for whatever reasons after several hours the mentioned malfunctions stop and everything works correctly.I am very concerned the dash display showing speed and other necessary information will malfunction while the vehicle is being driven.especially at night.being able to turn the vehicle off immediately is also important.this vehicle is regularly serviced by Toyota who have been unable to locate or correct the problem. I have researched this issue online and have found that there is a large number of Toyota Prius owners having the same type of safety issues with their vehicles. I have read but not confirmed that Toyota is aware of the mentioned problems with the Prius. There are some serious safety issues with this make and model of vehicle that need to be addressed as soon as possible. I hope NHTSA will be able to assist in this matter. Thank you.

The contact owns a 2007 Toyota Prius. The contact stated that while driving 65 mph, the gauges all failed. The failure recurred numerous times. The contact took the vehicle to a dealer for diagnosis and was told that the failure could not be replicated. The manufacturer was notified but offered no assistance. The vehicle had not been repaired. The VIN was unavailable. The failure and current mileage was 80,000.

The headlights on my 2007 Prius goes out constantly especially at night time there which causes total darkness and blindness. When I flip the switch they will come back on for a while. I know you know about this problem. I feel you should make Toyota recall these cars. The dealer will charge $300 per headlight to replace the bulb but we know that is not the problem. They wouldn't come back on if it was the light.. please please do something!! its terrifying and very dangerous. The liability for you and Toyota will be great should fatalities occur.

Approx 12/19/12 I went outside to start my 2007 Prius. When I hit the power button the car started up, however the dashboard lites did not work (speedometer, gas gauge, heat, A/C, etc). I turned the manual control wheel on the dashboard back & forth, thinking that would solve the problem but the lites still did not work. I backed out of my driveway and drove forward, thinking once I put the car in drive the lites would come back on, however that did not work either. I pulled the car back into my driveway, put it in park and hit the power button, but the engine would not shut down. I held the power button for an extended period of time and the car still would not shut down. I sat in it (in 32 degree weather) for about 20 min. And it shut down on its on. On the following day I took the car to Toyota & left it there all day long. They told me they could not determine why it had malfunctioned because the battery checked out good and all the diagnostic tests were all good. I had the same thing happen again on 01/13/13 and on today, 01/20/13. I do believe that this is a safety violation that Toyota refuses to recognize and I just want my complaint documented in the event something serious happens as a result of this situation. Thanks...

Headlights are intermittent on both sides. Major safety issue. I have replaced the bulbs twice in less than a year and the issue still persists. It isn't the bulb the headlights are defective.

  • 30,000 miles
The headlights on this car have intermittently worked since the car had about 30,000 miles. The lights randomly turn off. Usually one at a time but sometimes both go out. Turning the lights off and back on fixes the problem, but only temporarily. I read that this is a problem with the bulbs going bad but I can attest that it is a clear defect. Replaced the bulbs and it still happens periodically.

Total dash board failure.....design is composite so all instruments go dark except check engine light which is the least of a safety issue...instrument panel should have separate circuits so safety isn't dependent on any single point of failure.

  • 55,000 miles
The passenger side headlight frequently fails to turn on. Sometimes it turns on, then shuts off within the course of a drive. Sometimes it doesn't turn on at all. It seems like it must be a problem with the electrical system, as the bulb itself continues to light, it just doesn't light all the time. The driver's side headlight, in the mean time, is perfectly fine and never has problems, which also suggests some kind of electrical/connector issue.

The front headlight started going on and off periodically while driving, we went on a trip to hungary and the light started acting up. We have taken it to two Toyota dealerships within germany with no resolution but expensive bills due to the mechanics hooking it up to computer systems to diagnose the problem. This is causing us safety issues while driving especially on not clear days due to the early morning fog. I have consulted with my brother's body shop to see if there has been any recalls or defects on the lights, nothing. I am taking it again this week to the Toyota shop in mannheim germany. This problem has not been resolved since Feb 2012. I would appreciate some resolution to this problem before the lights cause us an accident. I have had the two front headlight bulbs replaced which are not inexpensive. Thank you if you need to contact me do it via email, this is my parents phone number in pa, I cannot type in my number in germany.
