Headlight goes out randomly. I turn the switch off and it will work for a while then go out again. This happens occasionally but I never know when it will go out. This is serious safety hazard. I went to the Toyota dealer Toyota of mcdonough (ga) and they said it would cost $750 to replace one headlight and the computer" that operates it. I can't pay that amount to fix one defective headlight. My research shows that this is a nationwide problem with the 2007 Toyota Prius and it is definitely a safety problem for the owner. Toyota is aware of this defect but as far as I can tell has not issued a recalled to fix it. What is the consumer to do" this is very dangerous! help

2007 Prius - started driving at night approx.9pm. Both headlights failed luckily still in town where it was well lit. Type of headlight was high intensity discharge (hid). This happened less than a week after my 36K mile bumper to bumper warranty expired. Dealer says that parts are extremely expensive as is labor (go figure).

Hid lights went out while driving on highway. Pulled over and turned lights off and back on, then it worked again. But after approx. 20 mins. Of driving, hid lights went out again. One time I didn't even realize that it went out, because I was driving in town, until I got pulled over by an police officer, who told me about it, but after turning it off and back on, the lights worked again. It seems to happen randomly and but more frequently during long trips.

The contact owns a 2007 Toyota Prius. The contact is experiencing failure with the high intensity headlight system. While driving, the headlights would shut off unexpectedly and cause dangerous driving conditions. Initially, after activating the headlight switch, the headlights would illuminate again. However, after two months, the headlights stopped working completely. The vehicle has been to the dealer numerous times. The first time, the dealer could not find any failures. Eventually, the dealer was able to duplicate the failure and stated that the light bulbs needed to be replaced. The failure has been repaired and the contact has found numerous complaints regarding the same failure and feels that the issue needs to be addressed by the manufacturer. The repairs were not covered in his warranty; therefore, the manufacturer did not hold themselves responsible for the failure. The failure mileage was 42,000 and current mileage is 53,790. Updated 12/4/08 updated 12/05/08.

Hid headlights on my 2007 Prius - the right light will go dim and eventually turn off completely. The left side will noticeably dim as well. I will turn off the lights, then turn them back on - and the right side and left side will return to "normal" brightness for a time - and then the same thing happens again. I consider this a major safety issue - I noticed this problem on a major vacation I just had and didn't want to drive on the interstate at night because of this safety problem.

2007 Prius - hid headlight problem, both come on when turned on then as I'm driving the drivers side goes out. If you turn off and back on both headlights relight, only to have this problem repeated. This is a safety issues which need to be rectified. This is a reported problem by many Prius owners and many are being charged hundreds of dollars for what is an apparent defect often not getting the problem solved.

Prius 4-cyl

  • Automatic transmission
  • 49,000 miles
Random, intermittent failure of either hid headlamp. Started around 48,000 miles. Turning the headlamp switch off and on again reignites the failed light, until the next random failure. The dealer is replacing the computer(s) that control the lights. They want to replace the lamps, but they cost $400, and are not covered under warranty.
