    I am having the same problem described here: the multi-function display (mfd) failed. (cross reference nhtsa complaint #10173892). This is a known design defect (cross reference analysis on web: http://techno-fandom.org/~hobbit/cars/mfd/compare.html and http://techno-fandom.org/~hobbit/cars/mfd/). Toyota issued a technical service bulletin (either el-002-04 or el-002-05 - conflicting info on this) on jan 10, 2005.…

    On my 2004 toyota prius, the lights go out randomly. Of course, at night. I took it to two toyota dealerships, and the first couldn't replicate the problem. The second dealership said the fix for one light would be an astonishing $850 because it's a defective electronic controller. Since my lights worked intermittently or after being turned on and off...and after searching the internet and discovering this defect is…

    The digital dashboard which includes the speedometer, odometer/tripmeter, shift indicator and fuel gauge goes blank. This creates a safety hazard especially during night or poor weather driving, and when shifting. My local toyota service department manager acknowledged that toyota knows this is a common problem, but refused to fix it at no cost. The service manager also told me that he must impound my car until the…

    I was quoted $466 just for the price of my bulb for the headlight of my toyota prius. For a non luxury car it so expensive that a lot of people will choose to make due with their flickering one. It is outrageous that toyota did not give a more affordable choice. It is going to be more dangerous out there. *tr

    Hid headlights go off intermittently while driving. Headlights can be reset by turning headlight switch to off and back on again. A search of the nhtsa and other websites demonstrate that this same problem is widespread for several year models of prius autos. The dealer estimates to replace the headlight bulbs is about $1000 per headlight, making this a serious problem because people will seek lower cost remedies…

This means i have had no navigation, air condition/heating, radio/cd and more due to this defective device.
