    On Saturday while driving the MFD “frozeâ€. The consumption screen showed no info apart from a new full bar every 5 minute period. Switching to the A/C screen showed a message†Check air condioner connection†and the audio screen announced “Audio Off†even though the radio was playing. The display & info screens seemed to work OK. After about 20 minutes the MFD came back to life, turned the radio off and showed apparently correct miles travelled and average consumption.

    The problem’s become more frequent until now (Tuesday) the same thing occurs when staring the car, the MFD coming to life after about 10-20 minutes, turning off the radio.

    While a temperamental MFD is generally liveable with if annoying, loss of heating/cooling controls is a pain! It certainly added a certain amount of hilarity to our holiday.

    Has anyone experienced similar problems or are there any service bulletins for this problem? My Prius is a NHW 20 T3 with cruise control added, registered in March 2004 so just out of warranty.

    Yeah, there's a TSB. If you search "MFD" under the care/maintenance troubleshooting forum you'll see a number of threads on this failure.

    That TSB is for the 2004.

    He has a 2003 that was registered in 2004.

    Not sure if there was a TSB for the Classic Prius.

    He said:
    That's a 2nd gen Prius...AKA 2004 MY. Sounds like the classic 2004 MFD issue.

    Better hope to God you got one of those Extended Warranties (tho some here say they're a waste :lol: ) because somewhere around $1,500 U.S.D. will get you a rebuilt one. Thankfully, even though ours was out of warranty (it began to freeze just after 36K miles), we got the extended warranty ~ so it was replaced at no additional charge. BOOM, the extended warranty just paid for itself, and THEN some :)

    For a new display module (not rebuilt) the part is ~$4200 USD list and $3032 discounted:

    (part number lookup using the TSB). Try seeing if Toyota will foot part of the bill, they have for other big expense problems on a car just out of warranty.

    Right, a rebuilt (if you can find one) is closer to $400.

    And in case the OP hasn't seen it, there is a thread on a refurbished MFD source:

    $1,500 - $400 ... so the tech made a little extra scratch off the warranty company. (s)he'll have a merrier christmas! Oh well :p

    Alternatively, if not already purchased, get the extended warranty before the 3/36k warranty period ends.
    But yea, the first hint of a glitch with my display and I went in to get a replacement after learning of the issue. Not even 100% the "blink" I saw was related, but I didn't car, I wasn't going to get stuck with a $400-$3000 charge for a new display. I'm pretty disappointed with Toyota on this issue. The interface is absolutely necessary to fully access all the features of the car an they know it's faulty. While replacing them all for free probably would dramatically cut into the narrow profit margin on the Prius, it still seems like the smarter move to reassure people that they're going to stand behind their cutting edge cars when they discover flaws.

    Perhaps it's worth a few posts to TMS USA's blog. Politely worded with emphesis on maintaining customer confidence and loyalty of course.
