I have a safety defect with the headlights on my 2006 Prius. The headlight on the right hand side was working intermittently. Took it in to the dealer. Told me that yes, it was working intermittently and the left side needed replaced also since it would be going out soon. They replaced both headlights at the cost of $614.

I have a 2006 Prius with hid headlights. I have a recurring problem which seems to be getting worse. When driving with headlights on, a headlight (sometimes driver side, other times passenger side) will just go off. If I know it has happened (very dark area or can see headlight reflections in the rear of the car in front of me), I simply turn the headlight switch off and then back to on. Both lights typically come back on. It is getting worse as I find it is happening more often. I am concerned that it will happen to both lights and cause an accident. I understand the gov.'t had a case open on this topic but closed it - found that only one light going out is not a safety problem. Hundreds (possibly thousands) of Prius owners also have this problem. Toyota seems to know there is some sort of issue with the hid electronics control board but is not offering to fix it for most people (read on line that they did fix it for one person free of charge). Faulty headlights sure seems to be a safety issue - is the us gov.'t waiting until several people die from this before admitting it is a safety problem" if only one headlight working is ok, then why can't all automakers just have one headlight vice two"

I have owned a 2006 Prius since February, 2006. I noticed (and so did the police who stopped me on three separate occasions!) the headlights working intermittently. This started in Oct. 2007. Since then I have had to replace 3 of the headlights and 2 of the headlight modules at a cost of $1589.35 total. The headlights stop with no warning. This is a safety issue, as I drive at night with my children and grandchild. The lights have only stopped one at a time, never at the same time, and I pray that they never do. I have contacted Toyota headquarters and they are reviewing my case to see if they can refund some of my out of pocket expenses for this. I would like them to replace my lights with reliable lights, but they are unwilling to do that. They have replaced my lights and module with the same kind of part as the original. Thank you for your attention.
