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.
#75 of 752 My 2004 Prius just died by pamsmom Apr 20, 2005 (6:19 pm)
I was stopped for a crossing guard and it just stopped. I have 12,500 miles on it. The Exclamation point in a triangle was there and I could not get it turned on or off - just all the warning lights. I had it towed to the dealer, although it eventually turned back on long enough to get it into neutral for the tow truck. The dealer mentioned there might be water in the gas. Sounds unlikely after everything that I've read here. I'll give them this website. Thanks. It's really scary when your car just dies in the middle of the road. I couldn't even push it out of the way until I managed to get it into neutral. It's a really neat car, but if you can't rely on it, it's not worth much. Anyhow, thanks for the advice.
#76 of 752 Re: Screen Failure [eprupis]. I also had all same, "A/C not connected" by ncarolina Apr 27, 2005 (10:09 pm)
Replying to: eprupis (Apr 09, 2005 5:53 pm) (This is my first posting... also did a search for prius computer problems and found this thread). I Dear Eprupis: You are not the only one. I also have had every single one of the exact same symptoms as well-described in post #67 "Screen Failure". The failure has occured about 5 minutes at a time, several times in last few days. Most of the time it seems to eventually correct itself. I'd like more info about the TSB that suggests replacing the screen #68). I've emailed the dealer with a link to this, and we'll see if they can fix it. FWIW, it seem to me like a software issue rather than hardware for this reason: when it has locked up and I have pressed a few buttons like Display, then Audio, then Climate it seems just like a windows-pc with a hung-program: after about a minute, the computer finally seems to process the minutes-old button pushes that were stacked up, displaying the 3 screens rapidly. Occasionally I see the "Air conditioner not connected" message upon first starting up in the morning, before hitting any buttons at all. If not software, then maybe faulty inputs due to moisture (hood seal). Or perhaps due to the pine pollen that coats everything like a green dust this time of year in North Carolina: I wonder if it is conductive?

#77 of 752 Stuck "Climate" button causes "Screen Failure" "A/C not connected" by ncarolina Apr 27, 2005 (10:25 pm)
Replying to: ncarolina (Apr 27, 2005 10:09 pm) I just found a probable fix in 2-28-2005 posting at http://john1701a.com/prius/prius-log183.htm namely, a stuck "Climate" button may be all that is causing the "Screen Failure" and "A/C not connected" as described in my posting in 76 and that of eprupis (68) John does not describe any fix other than unsticking a Climate button. Since it's happened a few times to me, I think I'll try to clean around the button and lubricate with a litte wd40 or dry-silicone drawer-glide lubricant to try to prevent the button from sticking in the depressed (down)_position.
