When ambient temperature is cold, sometimes dashboard lights and speedometer do not come on when the car is started. Car runs but with no instrument panel. Sometimes when the car is in this state the car cannot be turned off by pressing the start button. Car can only be turned off by pressing and holding the start button down for several seconds, and even this does not always work. This problem has been getting worse over time. Toyota dealership refuses to investigate the problem, but it is documented in their warranty repair t-sb-0172-09 combination meter intermittent display bulletin. Instead, the dealership tries to sell us a new car!.

The contact owns a 2004 Toyota Prius. On approximately 10 to 12 occasions, the vehicle would drive roughly and the instrument panel lights would illuminate while driving at various speeds. The vehicle had to be pulled over to the side of the road and turned off. After approximately five minutes, the contact would restart the vehicle, but the instrument panel lights would still be illuminated. The vehicle has been taken to two Toyota dealers and the location where the vehicle was purchased, but no one could determine the cause of the failures. The current mileage was 40,000 and failure mileage was 25,000.
2004 Toyota Prius - dashboard design defect. I've been troubled by the extent to which the speedometer display in my 2004 Prius dims when I used sun glasses. Today I took a moment and rotated the sun glasses in front of the display. My experience taught me that the display emits light. Polarized lenses are engineered to minimize transmission of this light. Toyota should cease using displays with these misoriented display elements as soon as possible. I have informed Toyota. They responded: your email has been documented at our national headquarters under file #200705150093. This seemed 'inadequate' so I'm submitting this to you. It would be pretty expensive to replace all of the poorly designed elements now in service.
Touch screen on 2004 Toyota Prius is defective and fails to work which leaves me with no heat at times and inability to see if my battery is operating properly, this is an ongoing Toyota problem with complaints all over the web by Prius owners.
: the contact stated when the weather is 10 degrees and below, the instrument panel did not illuminate or provide readings. This is especially difficult in driving conditions because the speed of the vehicle can not be read. The vehicle displayed the same problem several months ago, again in frigid weather of 10 and below. The dealer was notified and replaced the navigation system. After repairs were made, the weather was warmer and the contact was not able to confirm that the problem still existed. The manufacturer was contacted and replied this was a normal characteristic of the vehicle.
