MFD issues on '04/'05 Prius

I'd like to know exactly what part of the MFD is failing, and if
there's *any* chance that an electronically-clueful person could dig
in there and fix it. I remember Galaxee hinting a while back that
it was bad solder joints under a BGA, so if that's true then it's
out of reach of most home soldering rigs, but what if it's actually
something else? Or something that Toyota could do a mail-order parts
swap for just the board in question, for some nominal cost, for
people who aren't afraid to disassemble the MFD and just bolt on
a replaement? The one in my '04 is still okay, but you can be sure
I'll be all over the thing if/when it starts to go on me.

I know it sounds bad, but I kind of hope yours does go, hobbit. I know you'll dig in there and see what you can find. Of course, I hope yours doesn't go. You know what I mean.

Evan, very nicely put. Luckily, mine is (probably) not an early enough '05 to have this problem. But if it should arise, I'll be sure to get it fixed at Toyota's cost.

 

Evan: thanks for taking the time to bring this to Toyota's attention. So far I have been lucky with no MFD problems in my early '05 Prius.

Any thought about another on-line poll of chat members to get specific numbers of failed units?

 

2004 Prius with 43000 miles experienced a MFD failure. The car had the extended warranty, but, here lies the rub. When the Service Manager filled out the service invoice he listed the repair at $4200. Even though the Warranty paid for the service and MFD, it gets a lot of future customers attention when there are informed of this incident. Toyota must be out to sell Extended Warranties with advertising such as this.

 

I'll vote for a campain now!! :angry:

Mine just died today.. 115K miles..

What to do

I can probably replace it myself.. just need to get the part..

Anyone have a 2004 MFD cheap!!!

Any help would be appreciated...

Coincidentally, I saw one on e-Bay today, though I think it was a 2005. Might still work. If I'm not mistaken, the seller is the guy in Indiana who let Hobbit play in his Prius junkyard.

EDIT: Here's the link. It's for either 2004 or 2005 without factory NAV.

Thanks.. I emailed steve about that one..

Question for you guys who got one under the exchange program...

Is it one of the newer style.. that will not have this issue again?

I am afraid if I get one out of a junked prius.. that it will eventually wind up failing also?

Thanks for any help

 

does any body know if the 2006 mfd will work in a 2004 ?

No.. only 2004 or 2005 will work in a 2004..

 

Hey p626808, if you have to fork up out-of-pocket for the new one
and wind up with the failed one sitting around, would you be willing
to donate it to the research project on why they fail and how to
fix them? Or possibly dig into it yourself if you're into
electronics and such, using some of the ideas that have been floated
here and elsewhere on it?

Hey hobbit...
It looks like I a going to get a used one..
If that is the case.. you are welcome to the old one..

will let you know..

 

Replaced mine last night with one from a junkie in indiana.

Works fine..

Still will be sending toyota a little nasty message about what I think about there MFD failures..

Enjoy!

 

I sent an e-mail to toyota as well.. asking why a recall has not been done on the MFD.

there response..

Because there is no recall on the display...

That is what the e-mail said was the problem? that there is no recall..
And they don't know if one will ever be done..

So much for a good answer..

 

This just happened to my late 05 Prius with about 27000 miles on it. So still under warranty.

"air conditioner disconnected"; says radio off when it's on; 5 second lag on buttons; no data on milage screen; etc.

Is there nothing I can do beyond bringing it in?

Don't believe I have an info button...was this a feature on an earlier model?
I have a DICE unit plugged into my changer port. Hope this didn't contribute to this, or void my warranty...

If your still willing to give the old one to Hobbit, I can pick it up on my block heater trip and drop it off with him.
