What is this fluid dripping on my driveway?

I have a 2016 Kia Sedona, and have noticed these fluid spots on my driveway. I don’t know what they are! I don’t think it’s water based as it doesn’t evaporate even under a blistering sun.

Not sure if the darker spots fade into the light gray ones with time, or if they are unrelated.

Anybody could take a guess? Could it be the rustproof liquid? I have doubts though, since we get it rustproofed in the fall and leave the van on the street for many days until everything drips out. Plus, new spots have appeared since the spring.

Thanks in advance!

There is no way to tell what those drips are over the web . You have a leak so a good shop will put it on a lift and look for the source . Frankly I think you are wasting money on the annual rust proofing seeing as how it drips off after application. Also it might block the drains that keep your vehicle from rusting inside out.

Agreed about the rustproofing…any time someone tries to talk this up, I send them a link to this: https://www.youtube.com/watch?v=nXvl9nt57Kg

There’s no way to identify that fluid from the picture, we’d need to know the color and consistency of the fluid. You could put a clean piece of cardboard down in the driveway, or some white paper on the floor of the garage, and let it sit for a few days for fluid to accumulate. Or, like Volvo mentioned, just take it to a shop and have them take a quick look at the underside.

Given the quantity and dispersion of drips though, it seems unlikely that this is from a point source…are you absolutely sure it’s not the rustproofing? What kind did you use?

That video really gave me a scare and to my horror, I found out that we can also get ziebart here in Denmark.
That is really sad, because over here (meaning Europe) we can get several different brands of rustprotection for inside/outside protection and they do a really good job at keeping rust away if done right.
I drive a -95 car, known only to last 10 - 15 years before rust would kill it in our climate and winter road conditions - loads of salt, but due to it being protected from fairly new, it has not needed any welding as of now and it passed our bianually test with flying colours two days ago (no perforation allowed).
Of course I have to keep up with the undercoating as it wears off, but all cavities are done once and for all, and it takes probably 10 minutes a couple of times a year.
I expect that car to last many years more with regards to rust.

NB, I’ve never seen such a mess re. all the wires and everything which should not be covered with that crap.

I would argue that any car manufactured in the last 5-10 years does not need rustproofing. Yeah, there may be some edge cases/exceptions, but OEMs now do a far better job of rustproofing their vehicles from the factory than any aftermarket product could. I’ve lived in both the Midwest and the Northeast for a number of years, and there are parts that can rival even the worst European winters. As long as you wash your car regularly in the winter time to prevent too much grime/salt buildup…I can’t recall the last time I saw a new(ish) vintage car with rust issues on the roads here.

Really . . . ?

Park your car near the ocean for several years . . . watch what that salty breeze will do to the vehicle over time

I mention that because there are situations where the vehicle must be parked outside for years, because it’s a fleet vehicle, among several other possible reasons

Been living by the ocean for 15 years and haven’t had an issue with rust personally. I think people will get varying results based on a number of indeterminate factors.

Fair enough. Though never having lived by the ocean myself, I would make an even stronger argument against aftermarket rustproofing in that case. At least with winter weather areas (where I see and hear much of the anecdotal stories about these shops setting up), a bungled rustproofing job won’t hurt the car much if you only drive in dry summer weather. But on the coast, you’re right, that salty breeze will permeate through every crevice and sandwich itself between the rustproofing and the frame, even if the vehicle isn’t moved an inch. It’s just not worth the risk…every vehicle I’ve ever owned or ever will own is going freebird :smile:
