Wiper arms corroding? Any one else?

[Inazone]

Hi there,

 

While looking for a CT200H I did notice that quite a few had corrosion around the wiper arms just before the sprung part of the arm. My wife's car has this corrosion as well and her's is a 2012 fsport. Was thinking about removing them and cleaning them up and spraying them. Just wondering what other people have done. Or am I just the only one with this issue?

I have taken one of the arm's off, and cleaned it up and sprayed it matt black. Just wondering whether it's a design flaw or a known issue?
Out of interest, the facelift car's are the arm's interchangeable?

Morning, Yes a known problem, had mine changed on a 2013 premier Free of charge. Talk to your Dealer. Good Luck!

I doubt that they would entertain a 2012 car. Hence I never bothered calling them. I've just started sorting the passenger arm now. The driver arm came out fairly well.

Depends on your relationship with your Dealer.

I don't tend to use dealerships. Other than for spare parts. I've fixed the problem now. So they will definitely will not want to know now.... Lol

I had the same issue on my previous RX400h and RX450h.

I must say I am a bit disappointed with the quality, although the arm's look well made, its the powder coating that's let them down. Mind you the arm's on my Supra are still good after 26 years....

If you need to remove the arm from the drive spindle easily I found a small ball joint splitter works well. Slacken the nut but don’t completely remove it to protect the threads, place the splitter under the wiper arm and gently tighten the bolt onto the loosened nut to break the taper off the splines.
