To date we have not had an incident, however I believe the failure of our headlight and the lack of Toyota to correctly identify and correct this problem is unacceptable. The failure occurs everyday while driving the vehicle. We were told by the dealership to replace the bulb. The cost of the repair is over $500. After reading many complaints, the wiring or connection seems to be the problem, not the bulb.

Hid headlights on 2006 Prius keep failing. First failure at about 14K miles; two failures between 20K and 30K miles. Total of five hid failures: 2 for passenger side light; 3 for driver's side light. Failures are intermittent, often while driving. Hitting hid lamp lightly often restores light. Initially bulbs were replaces (twice). Subsequently, the entire unit (including computer board) were replaced. Bulbs should last life of car-- neither original hid light lasted the first year.

My 2006 Toyota Prius has a problem with the driver's side hid headlight intermittently going out while driving. The light simply goes out on its own. To get it too come back on, I have to completely turn off the headlights & turn them back on. This is very dangerous at night. I have had this car only 2 years but, since it has 50,000 miles on it, the dealer will not fix it under warranty. They want to charge $1300 for a new computer circuit board, headlight & headlight housing. According to other Prius owners on the discussion forum at www.priuschat.com, this is a widespread problem with the 2006 model Prius. So far, Toyota has not issued a recall. As this is obviously a serious safety issue due to defective parts / manufacturing, they should do so immediately.

My front headlight does not always work reliably. It will stop working sometimes when I am driving, but may return to normal operation when I power off the car. When I tried to get this repaired, the technician could not find anything wrong. After researching on the discussion boards, I have learned that there are many other Prius drivers that have this same problem. The car is only 2 years old. I believe that there is a design issue with the headlight drive electronics.

: the contact stated that there were on going problems with the vehicle stalling. Also, the gas and mileage gauge were unreliable. The last stalling failure occurred on the freeway while driving 65 mph which was the third incident. The dealer determined that the gas and mileage gauge were unreliable because of the way it was manufactured. The problems persist.
