Defective HID Headlight for Toyota Prius. Theres is a wide spread failure of these lamps and both the dealerships and Toyota are raping consumers, charging at least $325 dollars to replace EACH headlight. Also, the premier Platinum extended service agreement (paid $2000) sold by Toyota does not cover these defective parts. My other headlight ceased to work the same evening that I had replaced the one headlight on my 2008 Toyota Prius for $325 dollars. THIS IS A SCAM.
