Hid headlight in 2007 Toyota Prius keeps going on and off. This is a known issue with Toyota. It is expensive to replace the bulb. I wanted to add my name to the list of people affected by this problem.

Toyota 2007 Prius (us model) hid headlights are intermittent. This has been going on for years and replacement bulbs don't fix the issue. Lights may extinguish at any time with no warning creating a dangerous driving condition, particularly at night. Thousands of owners have complained about this issue, but no recall has been provided by Toyota.

Hid headlights work intermittently and randomly. When it first occurred, I replaced one lamp. It continued to work intermittently. Now both will work randomly. When one goes out, you can turn the headlight switch off and back on and both will work.

Headlight and tail light on the passenger side of our 2007 Toyota Prius goes on and then off. We can't depend on the lights to stay on.

The headlights on my Toyota Prius failed. Came on some times then after turning on and off. The wire harness to the bulb of the headlight seem burnt, and after reading hundreds of complaint just like this, Toyota has a problem-I have a problem -hundreds of dollars to replace headlight bulbs is insane and not the only issue here.

For some time I have been telling the dealer that I have been informed that one of my headlights is out but when they look at it at a later time they are working. I suspect that they have been doing this for a long time. Now it appears that there is a progression. Both headlights unexpectedly turned off plunging me into total darkness while driving at 70 miles per hour on an interstate highway at 5:00 in the morning. I found myself hurtling along in total darkness. I turned the light switch to the off position and turned it back on and the lights came on again but they went off again a few miles later and I went through the same process to get them to come on. The situation happened at least 5-6 more times before I reached my destination.

The passenger side hid headlight on our 2007 Toyota Prius goes on and off while driving. Toyota has sent us a letter advising us that they are aware of the problem and are willing to repair the problem by offering us the bulb at half price, approximately $150. However, after doing some research I have read that the bulb may not be the problem and repairs could total $2000. Since the problem occurs without warning I am concerned that at some point the other headlight could fail and cause total loss of vision at night resulting in an accident.

Headlights go off for no reason. We have a 2007 Toyota Prius with 58K miles on it. Over the past few weeks, we've noticed the head lamps going off and coming back on. This is happening on both sides intermittently. My wife was driving to work in the dark the other morning and both headlights went out at once. She was able to turn off the light and turn them back on to restore her road vision. They stayed on for a few minutes and then the left one went out shortly afterwards. The car is now at courtesy Toyota in brandon, fl and I'm being told the "ballasts" and the head light bulbs need replacing. This repair is costing us over $400. Toyota claims it is not covered by warranty and there are no existing recalls.

My 2007 Prius started having right headlight failure when I would drive on a rough road it would turn off then back on some 6 months ago. My husband checked the wiring and it came back on. The car had 45000 miles on it at this time. About 3 weeks ago both of them started turning on and off and 2 nights ago while driving home I had to turn them on and off 22 times and they would come back on and then get dim and then turn off. I took it to them at the dealership and they stated the left light was bad and the light and ballast were replaced for the tune of 614 dollars. They did nothing for the right light. I called and opened a case with Toyota who will not pay for ay of it. This should be in a recall!

2007 Prius (69K miles). Driving on highway, all caution lights came on. Towed to dealer and diagnosed with a 12-volt battery issue. $280 to replace the batter. Three weeks later, same cautions lights. Got most to clear with a restart with the exception of the "master caution" and the "engine check" lights. Dealer showed code of "P0A93" and stated inverter coolant pump needed to be replaced for another $486. Check online shows Toyota knows about the pre-2006 issues and that many 2007 and beyond owners are running into the same issue at various miles.

The headlights on my 2007 Prius come and go. The problem is a defect in the headlights and the fix is more than $500. For the headlights. This is really dangerous because I think there is a problem and I look they are okay. Then someone tells me my headlight is off and it is but when I look at it later, they are working. I suspect that they have been doing this a long time but I did not realize it. This is dangerous. I want a recall!! this is worse than the pedal problem.

Summary: My car began accelerating while I was in park. I own a 2007 Toyota Prius. Two days ago, I drove to my destination, pulled into a parking spot, and turned off the car. I was early, so I turned the car back on (so I could listen to the radio while I waited). The car was in park and I did not have my feet on any pedals. The car was on for less than a minute when it began to drive forward. I both heard the sound of the motor engaging and visually processed that the car was moving. I immediately stepped on the brake hard and the car immediately came to a stop. My 4-year-old was distressed because the rolling and hard stop made a big jolt. The car was still in park. I released the brake pedal and the car stayed still. I do not know if this is related, but my car headlights randomly turn off while I am driving. If I toggle the switch off and back on, they always come back on. I took it to the local dealer, where the repair guy told me they frequently see this problem, and all they do is replace the headlights (which made no sense to me, because the bulbs aren't burned out). I would say this problem happens about once a week.

  • 35,000 miles
The contact owns a 2007 Toyota Prius. The contact stated that while driving at 48 mph, the brakes suddenly locked up and swayed to the left side when he depressed the brake pedal. The vehicle was taken to an authorized dealership for diagnosis. The dealer repaired the axle and driver side body but it was unknown if the dealer repaired the brake system. The contact believed that the rain was a factor in the failure as it caused the computer chip for the brake pedal to malfunction. The braking system for the vehicle failed periodically in rainy weather. The VIN was unavailable at the time of the complaint. The failure mileage was approximately 35,000. The current mileage was approximately 60,000.

Intermittent headlight operation on hid headlights 2007 Toyota Prius. Both headlights went out at the same time while traveling on I75 last night. After almost wrecking, we pulled to the side of the road. After turning lights off for a while they came back on and started working again. This seems to be a frequent occurrence according to blogs on the internet. I contacted the dealer and they said if they had to replace the unit it would be in the thousands of dollars!!!!! ($1100 for headlight computer, $500- $600+ for headlight bulbs and another $1100 for light kits) I think that is completely ridiculous to expect someone to pay that much just to be able to drive there car safely! none of this was revealed when the car was purchased! how could anyone expect to pay that kind of money to keep there headlights working? please help, we cannot afford to drive safely now!
