#686 of 752 LCD screen and Navigation problem by bri4 Apr 10, 2006 (5:05 pm)
I purchased a 2005 Prius with the navigation package version 04.2 on 6-22-05. On February 23, 2006; I witnessed the screen lose half the brightness, and road lines, instead of being smooth, are now segmented(jagged).The colors in other displays have also changed color and darkened. I would like to hear from anyone that has experienced this and what remedy Toyota offered.

Replying to: bri4 (Apr 10, 2006 5:05 pm) Isn't this covered under warranty? Have you asked a dealer for a diagnosis? Replies to this message: bri4 (Apr 12, 2006 4:38 pm)

Replying to: bri4 (Apr 10, 2006 5:05 pm) Is your Prius under warranty? Don't bother asking - just take it in. It appears to be a simple failure of the LCD.

Replying to: looking4prius (Mar 07, 2006 2:38 pm) You can get a cover that matches the interior of the Prius on Ebay - designed for it, as a matter of fact. We have a Prius and just bought a Hightlander Hybrid we were so happy with the Prius. Glad we got the Highlander this year - I don't like the look of the 2007! I've got a question - Does anyone know if the 2007 Prius will have a moonroof option. I'm a bit afraid to go aftermarket on this vehicle. Not enough people know how to work on them that have been trained ... don't want to mess up anything on it. Let me know if you know. Thanks & Peace, Patty

A lot of problems have bee traced to HMI and reprogramming or retirement of the older HMIs has fixed the problems.

Replying to: jrct9454 (Apr 11, 2006 4:58 am) I took the car to the dealership and they observed the condition. The service manager called the Toyota Service Rep. and responded back to me that they are aware of the problem. The dealer service department could not help me. An appointment was made with the Toyota Manufacturing Service Rep. We drove my car and another used 2005 Prius. The Rep. concluded that both systems have the same characteristics and I agree. My contention is that they tested it against a used car with the same problem instead of a new system of the same version. I was told that they don't have any. I told them that their test method is wrong. I have since had numerous conversations with Toyota headquarters Torrance. They say they can't help me and have forwarded papers for arbitration. I cannot understand the reluctance to fix the system that has degraded within seven months.

Replying to: dorisnichols (Mar 18, 2006 3:53 pm) I've had the same problems with my '04. It has been serviced numerous times by the dealer whose techs look lost when the issue is explained to them. They usually hook it up to some service-mandated computer propram that "updates" the computer software. But it is clear that few if any of these guys have any real experience working on this type of car. Its like my attempting to explain how a VCR works on the basis of my ability to program it by pushing a few buttons. I would suggest taking yours to a Toyota dealer and requesting a "computer software update" that they say can improve the mileage. I just did mine but I was not impressed by the results thus far. Hope this helps...
#693 of 752 Re: Prius center console problems 61,000 miles [rakers] by mrosa Apr 21, 2006 (11:12 am)
Replying to: rakers (Feb 02, 2006 11:10 am) I was just wondering if or how your situation was resolved. I've been having the same problem for months and 2-3 trips to the dealer have failed to improve it. In fact, I struggle to get 43-44 mpg whereas I was around 50 mpg in the Fall. The reasons they gave included changes in the type of fuel used in the West (Ca.), gas gauge problems, and a colder than usual winter. My trump card might be that since I have reported prior to the expiration of the 3 yr./36,000 mile warranty, that I might be saved. Also, I noted that it says next to nothing about the on-board computer in the warrenty booklet. Have you any info on that?

Replying to: rakers (Feb 02, 2006 11:10 am) Thanks for sharing your stories. I took my 2004 Prius in yesterday at 43,000 with the same issue: radio cuts off, outside temp goes blank, climate screen says "check connection to air-conditioner", loss of function from temp up or down buttons on steering wheel, etc, etc. They said the center console unit would need to be replaced - for $4100, plus 100 for labor. I repeatedly asked if there was not a loose connection or a defective sensor, or if it could be a programming glitch in the recent recall reprogramming - and the answer was 'no' to all. They also said it was not covered by the hybrid system warranty, but that they would re-check with Toyota and I should get back with them next week. So I drove home, and noted that all systems are working again..for a while. I'll advise them to read the service advisory, check for the loose connection noted in it, and then, if replacement is still the only option, tell them of the precedent of the offer to do it for $600. Do we know where the dealer is who made that offer? and I'll add my own observation of milage dropping from my usual 52 average down to 46-47 since the recall 'fix'.
#695 of 752 Just got a $3500 repair bill!!! by kallen2223 Apr 30, 2006 (3:53 am)
Hi all - I have a 2004 Prius w/86,000 miles on it - I drive a lot for work. I have taken this car in regularly to have oil changes etc., had the reprogramming done when the recall came out. This week I had the issue of the radio going in/out, climate screen saying "check connection" etc. I took it in and after 3 hours the service dept tells me that the center console has to be replaced at a cost of nearly $3500. He said that because my car has such high mileage Toyota won't offer any reduced cost, etc. I see from the posts that others have had this problem. Is there any resolution other than with coming up w/all that cash? I have talked up this car to so many people and have been a big influence on at least 3 others to buy Prius - now I am wondering what happened to the Toyota quality I had heard so much about and believed in.
