My dashboard went off sometime ago. I took it to the dealer and they could not tell me the exact problem but said it will cost me $1800 to replace the computer on the dashboard.
I left and drove the car without gas gauge, speedometer and odometer. I used my phone GPS to guess my speed so I never got ticket for overspeeding. Then after six weeks it came back on by itself and everything works just fine.
I traveled to Florida from NJ for 3 days and upon returning, the dashboard went off again.
What is actually causing this problem and is it one of the many sicknesses of Toyota Prius or it is a hybrid car problem?
