2004 Toyota Prius Owner Comments

problem #4

  • 25,000 miles


Regarding my 2004 Toyota Prius: The 'multi-information display, I.e., computer display, does not function frequently, at which time a message saying the air conditioner is disconnected. Simultaneously, when this message appears, the radio instantly turns off. When this occurs access to the computer is impossible, controls of the air conditioner system are unavailable except through those on the steering wheel which continue to function. The computer function later randomly is restored for brief to long periods but remains subject to random failure again. This failure has existed for years. Dealerships refused to take responsibility for repair or replacement of the equipment. This defect is a major distraction to safe operation of the vehicle. For example, during computer shutdown periods, it is impossible to alter air conditioner fan speed during freezing ambient weather.

Started my 2004 Toyota Prius and placed vehicle into reverse to back out of parking space at daughter's school. Car died while backing, blocking traffic, and would not restart. Orange light glowed on the starter button. This is 7:45pm. Called original dealer in Washington pa for advice. No help. Looked in owner's manual for advice. No help. Called local dealer in charlottesville va. No help. A male teacher opened the hood and fuse cover to ensure that all fuses were snug and secure. Nothing. After about 30 minutes, the car finally reset its self, the starter button went green and when tried the car started. Told the local dealer of this incident and they denied any knowledge of any trouble like this. Coinsidently, my gps system had failed just a couple of days prior to this incident. It took a month to get it replaced.

I would like to report a stalling I experienced while driving our Toyota Prius (2004) the car stalled a little after I merged onto highway 85 in cupertino. All the warning lights on the dashboard came on and the car would no longer accelerate as I tried to drive up to 65 mph. It appeared that the gas engine quit and it was running on electric power. I was able to coast on till the next exit. After getting off the freeway, I pulled into the nearest parking lot where I turned to car off. I was able to restart it and it drove fine but all the warning lights remained on. So I immediately drove it to the dealership in sunnyvale where we bought the car where it was fixed. I am not sure that Toyota dealers are keeping accurate records of the problem. I read an article in the Mercury news today's edition in which adam simms, the operating partner at Toyota of sunnyvale has claimed that "none of the people who have bought a Prius at his dealership have had problems with stalling". I know this is not true because I have experienced the problem and had it fixed at his dealership. I am not sure of the exact date the incident occured. I believe it was sometime during the the second week of Nov.
