I have seen the rust for a few years but never paid much attention until this morning. I think it's getting worse than I thought and almost rusted through (attached photos). I wonder if there is any way to seal the area to stop or at least slow down further rust. The alternative is of course to have it properly fixed at a body shop. Surprisingly, the other side is perfectly fine with no hint of rust.

Wow, that is pretty bad!

My '03 also had rust in the same place, but barely visible when I traded it last year due to the front frame suspension member rusting almost completely away due to AC condensate dripping in it...

Your rust area has been mentioned a few times over the years. Usually there's a lot more rust that you can't see... I don't think there's a way of stabilizing what you're experiencing without cutting it out, seeing what's behind it, and welding in new metal...

I'm sure that's the right way to deal with it. I have a smiling. Amount of rust on my wifes Honda. I waited until it had dried out well, gave it a good clean with a wire brush, added a Waxoyl-type product to the underside and brushed on Loctite Rust Preventer - other products are available - on the painted side. The rust has stabilised and has not spread beyond it's original area. Depending on your abilities and needs, this was a quick, simple and so far effective way of dealing with it. Some will come on now and say that the rust will be continuing unopposed, etc. And that is a possibility, but visually it is as it was 2.5 years ago. All the best.

The ideal thing to do is to remove the rust completely down to bare metal and cut out the really bad sections if necessary (which would require some welding to repair). Given the age of the car, this probably wouldn't be economically feasible unless you could do it all yourself. One other option is to remove the rust as best you can and use a rust converter which oxidizes whatever you missed and dries to a paintable surface. Rust-Oleum makes a variant called Rust Reformer and there are many others. If done well, such a repair should easily buy you a couple of more years at least. First try to find out exactly how bad it's gotten, especially the areas you can't see without removing panels etc. Good luck and let us know what you decide to do.

Thank all for the replies. I will look into the possibility of DIY using the rust inhibitor. I haven't done body work and have no welding equipment. I may take it to a body shop for a rough estimate to see how much it would cost. If it's $500-600, I may consider it but I doubt it. The car is still in good shape with 148k miles, but with the unpredictable CVT, I don't feel like to spend a lot of money on it.

@ Wolfgang Huang - The rust you are experiencing is not new or unique to your MO. It has been reported by many others in this forum as eluded by
MuranoSL2003. The rust is most likely due to moisture retention behind the panel beading seal. The only way to get rid of it completely is by removing the panel and replacing any badly rusted and pitted metal with clean metal (welding) and repainting with rust proof primer first before applying the final color coat... You may be looking at a significant labour cost which may not be justified for a aged car with unpredictable CVT. Good thing is it is not a critical part which can result in any major accident if it fails...Also it is not visible when you close the door. so it is only a hidden cosmetic issue at this time..I wiould accept this and adapt to live with this rust 🙂

If you decide to live with it, maybe some white duct tape or similar will help a little with the cosmetics.

If can I get the rust inhibitor/remover/reformer to work, I will try to live with it. It's not cosmetically offending since it's hidden behind the door. I have not done anything yet. Will report back when I have.
