melted back door/hatch/tailgate handle?

I just called my dealer to get a price on the little rubber button/handle release for the back hatch/tailgate on my sienna, and he said this is apparently becoming an issue on lots of 03-up 4runners and 04-up Siennas that use this type of back door release. But apparently there is no TSB or SSC for it that they know of.

I'm in Houston, TX. It gets hot, but i didn't think it got THAT hot... not to mention the fact that this handle is shaded from direct sunlight by the tailgate trim anyway.

So... Has anyone else here had their back door handle melt or at least get gummy/sticky?

My wife's 4Runner (2008 MY) has had the problem for a little while now. While I'm a Tacoma guy, I looked over here specifically to see if anyone had a fix and saw your post.

EDIT: Found a reference about how to DIY repair: http://www.toyota120.com/forum/showt...109#post121109 Took me about a half-hour to R&R.

Part number for a 2008 Sport model (same "I think" for all models from 2006-2009) is 84840-35010, Switch Assembly, Back. My local dealer charged me $46.82 with a list price of $58.53.

there's a thread on it over in the sienna section here on TN. same part number covers 4runner from 03-up and sienna from 04-up.

wonder how hard it would be to replace the rubber cover part with something more durable and less likely to melt...

Thanks for all the posts, I was just at my dealer today in hopes to get my Melted Switch cover replaced on warranty. I have a 07 Sienna and the rear hatch switch leaves a nasty smear of black melted rubber on my hands every time I open the back hatch. The dealership quoted $260 to repair with a new switch assembly and my extended warranty didn't cover it since the button itself did not have a "mechanical problem". I said no thanks, left frustrated... and will attempt the repairs myself suggested above. The dealer also said they have never seen this problem almost implying it was my fault.
We are in Charleston, SC where it is pretty hot but as Gibson99 says... it shouldn't get hot enough to melt the cover.

melted rubber cover

I am in Maryland - it is 100 degrees today and my rear latch felt like tar when I pushed it in. I thought it had some solvent or oil on it so I tried to remove it to clean it up. I tried to unscrew the cover but the screw head stripped and the rubber pulled off like playdough.

Now I have a ball of rubber, an exposed switch that still has the rubber residue on it. Another simple car repair!

Have this problem in our "07 4 Runner. Hot and humid here in Memphis TN area. Must be some kind of breakdown of the polymers...took 4 hot summers to happen. Gotta get this fixed, will try the do-it-yourself route.

My wife's 2007 has the same issue. We live in Phoenix so I just figure we were a victim of the extreme heat, but now I see it is a bad part. Will have to try the DIY fix before it heats up again and we get black fingers.

Melted rear handle

Have same problem with my 2007 4runner here in San Diego. Wrote to toyota US, they redirected to local dealer. Dealer reaction was I probably applied some chemicals during cleaning. Really Toyota?

07 4 runner sport - melted back latch

I have the same issue on my 07 sport edition......seems like a very broad-ranging issue after reading these posts, I thought it was just the Texas heat! Toyota should offer a fix.

2007 Sienna

From southern Orange County, CA. We have 2007 Toyota sienna with melted back door/hatch. I went to Buena Park Toyota Dealer, customer service guy said he is seeing a lot lately with other Toyota models and he can't do anything about it, because it's not under warranty. So he suggested to me to call Toyota headquarter. We called Toyota headquarter and spoke to Rachel. She took our information, then she directed us to specialist. Diana took all the information again, then she suggested three way call with service department manager. So she put me on hold for a few minutes. Then Diana said that she spoke to the service manager and said it's broken Handel and I need to fixed for around $300.00. I laughed and said it's melted rubber, it shouldn't melt in less then 100 degree heat it's a Toyota defective part. And then come to find out she's not even a specialist, she's only a customer service person. THAT IS THE LAST TOYOTA CAR AND MINI VAN I'M BUYING.

I've got the same problem. I'm in South West Florida, and yes, the handle on my 2008 Sienna melted. The back door does not open from the interior switch either. Took it in to Palm Toyota in Punta Gorda where we had bought it from, new, and they told me it would cost $276 to fix it. She said she had reported it to Toyota head office, and that it was only happening to cars below Tampa, which now I am reading is a total lie. I am beyond brassed off, I understand if somehow I had done something to cause the problem, but it is sub standard materials used on the behalf of Toyota. So shortsighted of them, we will be in the market for a new Minivan in the next year, and as much as I like the Sienna, this has soured me completely.

We had the same problem on our 08, but it happened shortly after our car was detailed with a hot pressure washer... we assumed they caused it.

you can't get just teh rubber part. you probably don't want it anyway since the rubber goop gets pushed up inside the switch itself and gums up the mechanism.

i was sitting behind a sienna at a red light today and its handle had melted so bad that it was hanging down like nasty little flexible black icicles - some over an inch long. this is pretty crappy of toyota to continue to ignore such an obvious design flaw, esp on vehicles that don't have power rear doors - this nasty goop is the only way to open the back door when you don't have a power liftgate. heck - we DO have a power liftgate on our XLE and 75% of the time i still open it with the gummy rubber button because i don't want to wait for the slow motor to open the door for me.

i think once i get tired of the gummy button on mine, i'm going to cut a plate of metal to replace the existing junk switch, then install something like this:

http://www.gamainc.com/site/epage/130294_941.htm

a weatherproof pushbutton for $5. since it's made of solid plastic it won't melt like the crappy toyota part. plus it'll give me a nice flat area to mount a backup camera.

Going back to stock(ish): Click here to buy my stuff! TRD, whiteline, JPP, autometer, greddy, more!
