Since September of 2014 I have had issues with the dashboard lights. They have become dimmer and dimmer. Then during the week of 8/24/15, I started my car and the dashboard lights came on, but when I turned on the headlights, all dashboard lights went black. I had turn signal lights, but nothing else unless I turned off the headlights. This was extremely dangerous as I was driving home after dark. I had no idea how fast I was going, what gear I was in, if I had enough gas to get home, etc. , etc. The next morning I took a 20-mile drive and when I stopped, I could not get the car to shut off by pushing the ignition button. I tried multiple times and the engine finally turned off, but the display panel was still dimly lit. I then drove directly to the dealership to have whatever was wrong repaired. After a mechanic checked it out, it was determined the computer needed to be replaced and they had to order the part. This is not an item that is normally serviced and I have no clue if the dealership checks it during a servicing of the car. So I wondered if there was a recall on it. In checking on this website I find I am not the only person who has had this problem and that I thought there would be a recall on it. When I picked up my car I asked about the recall and I was given paperwork stating it was a "warranty enhancement program" for "9 years with no mileage limitation from the date of first use or before September 30, 2013". Letters were sent out to Prius owners of cars from 2004 to certain 2009 models. I never received a letter and am very concerned if Toyota knew there was a problem why didn't they not do just a "warranty enhancement program" but a recall? they would that eventually all cars would have this problem and it should be replaced. This is an extreme safety issue!.
