Replying to: teleman (Apr 08, 2005 12:55 pm) There is a recall or TSB (not sure of which) that addresses an issue with the gasket that lines the hood. Rain/water can enter here and cause problems . This MAY have been what caused your problem. Though I do think there CAN be software issues, then why aren't more cars effected? Isn't the software the same in all the cars?

Replying to: falconone (Apr 08, 2005 3:03 pm) It could still be a software issue. It is very difficult to predict when software will fail. A hidden bug might stall the vehicle, but only when a lot of different external conditions are met. Also the order in which these conditions appear might influence the process. These external conditions and the correct order to trigger the bug might happen only once in a million "car-years". It's a little bit like the aerospace industry. In 1994 a Boeing 737 suddenly turned over on its back and crashed straight into the ground for no reason. Everybody was puzzled what had happened. Finally it turned out that all 737s had a design flaw related to the rudder. The 737 came into service in 1967, and every day thousands of 737s are taking off and landing safely, so it is very weird that the flaw went unnoticed for all those years. Still it did. But finally, when all the external conditions were met, the accident happened.
#67 of 752 Screen Failure by eprupis Apr 09, 2005 (5:53 pm)
I have a 2004 with navigation--one year old and 16000 miles. Today my touch screen stopped working. The info screen dropped the mileage number, the mpg calculation, and the current mpg plus the outside temperature. The energy screen showed the diagram but no movement of energy. The audio and map screen did not function and the climate screen showed a message that the air conditioner was not connected. All the steering wheel controls functioned and the air conditioning responded to those controls as did the audio system. The green dash info stayed functioning and the car drove normally in all other respects. I did get the display screen to come on and hit the display off button and now the screen will not come on at all no matter what button I hit. I have seen software operating failures on this board but this is a new problem I don't recall reading about. Of course I'll bring it to my Toyota dealer ASAP, but they seem to be clueless abouty the Prius' unique features. Any ideas?

Replying to: jkraft3 (Mar 24, 2005 11:26 am) I don't believe I have yet seen a posted response to your query: "are there continuing software problems with model year 2005?" Did anyone respond back? I am also very interested in learning that answer, as well, particularly after reading no less less than 15 pages, at the National HighwayTransportation Safety Board site (NHTSB) devoted to complaints, defect investigations, and service bulletins, on the 2004 Prius. The problems cited did not appear to be trivial and let's face it, repair costs are only part of the dilemma the owner has to deal with when malfunction happens--and often at the most inopportune times. While it is impossible for a consumer to dodge all the problematic auto "bullets" out there, it is outrageous for a manufacturer to remain silent/not respond to consumer complaints on cars that have been out in the market for close to eight years now.
#71 of 752 Prius Computer by parklandtoad Apr 14, 2005 (4:36 pm)
My 2004 Toyota Prius computer malfunctioned right in the middle of the most dangerous intersection in my city in clear, dry daylight conditions. Every warning light came on and so did a big "problem" message light. The car continued to drive, using mostly the electric motor, and I was able to reach a local Toyota dealer a few miles away. They told me my computer had to be "reset" and asked if I had gotten notice of a recall for the computer on my vehicle. The answer is "no" to the recall question, but now I am concernied that there is a recall out there for the computer on the 2004 Prius. Replies to this message: stevedebi (Apr 18, 2005 9:00 am)
#72 of 752 failure today by khs Apr 15, 2005 (2:00 pm)
My 2004 Prius (3300 miles) suddenly beeped and warning lights came on, inlcuding red triagle, engine warning, etyc. Took to dealer--ECM reprogrammed. Service person told me "this has happened to almost all "Prius' they sell. If happens again, just drive to Toyota Dealer--nothing to worry about--no explanation." I just finished reading these messages. I plan to pursuewith Toyota and file a complaint with NTSB Replies to this message: gagrice (Apr 15, 2005 3:41 pm)

Replying to: khs (Apr 15, 2005 2:00 pm) Service person told me "this has happened to almost all "Prius' they sell. Welcome to the forum. At least the Service people were honest about the occurrence of the problem. Many act like it is a fluke and have never seen it happen before. Did the car quit or just all the Warning lights came on? Did you buy the extended warranty? How do you like the car? Would you buy another one? Good luck with getting an answer. I am sure that Toyota is aware and working on it. It does not hurt to make the NHTSA aware of the issue.

Replying to: parklandtoad (Apr 14, 2005 4:36 pm) Be sure to file a complaint with the NHTSB... it is the only way to get Toyota's attention.
