Yes, it is really cold, but something that I have noticed the was never a case with any of my past cars is the amount of ice that is forming on the inside of the windshield. This has me more wondering as it might tie in with the distinct smell of windshield washer fluid when you use the washer/wiper option. As I get this issue with both of my Niro's, I am wondering if this is just a design issue. Tag that along with it takes just about forever for the engine to warm up, and the defrost option even with the aux heater takes just too long to work. If it was condensation inside, then just having luke warm air would work, but this is a good 1mm of ice. Short of using an actual ice scraper on the inside of the windshield, you are stuck to see. I was told on past vehicles that trying to clean that off just makes the situation worse as you end up with smudge marks and haze on the inner part that then requires a good cleaning. Not something that you'd plan on doing every time you get into your car to drive, especially in the freezing cold of winter.


What is the interior ice situation like for others in cold climates?

Hi Roadkill401, It happens more the car is shut down when the selector is at the defrost and there is water or snow on the carpet of the vehicule. i use a wool sock with some cat's litter in it. placed under my seat, it absorb a lot of humidity in the car. for now it works, even when i had my Rio5..

No better or worse than any other car I've had .. I use the Weathertech mats so the carpeting doesn't hold much water. When it is real cold, windows do frost up but the one button on the console clears it up quickly (although it takes heat away from the feet.) You are sure it is not cursing while driving the 401 in T.O.? (only joking I grew up there now live in Ottawa). As you know January has been super cold and super snowy (with more on the way). The cold really kills the fuel economy.

i have the tuxmats so they are like the weathertec in the carpet doesn't absorb any of the water, it just pools at the bottom and then you have to deal with that as it melts. I had a Ford Edge before the Niro and it had the WeatherTec floor mats and to be honest I never had this sort of problem. But that was for the past 3 winters and not this one, so as it's not the at the same time, it is impossible to say that one car was better than the other. the 3 winters I had the Edge, I can't say we had it nearly as cold for as long with the same weather patterns and snow fall.



I will give putting a sock with some of the silica crystal litter to act as a moisture absorber to see if that helps out a bit. the Aux heater is the electric heater booster that is inside the car, but it seems in this -16c and lower temps does little to nothing and you are just stuck with cold air for at least 5-10 minutes for the engine to warm up sufficiantly to actually defrost the front. If everyone else is having the same problem then it's not a build problem but just a design issue/fact of life.

Oh, you are talking about the PTC heater. No noticeable effect. No way to tell if it is even working, but it is on the parts list.

I don't have any first-hand experience with interior frost on the Niro, due to the climate where I currently find myself. But when I lived in more northern climes, I had a habit of always cracking the window on other cars I've owned (even in sub-zero degrees F) until the defroster was at a point where it could be effective. The idea there (which seemed to work for me) was that your breath can fog and even ice the interior windshield, but if you crack the window, the interior humidity doesn't build as fast. I also do this when it's a reasonably warm day, but raining, and I've just gotten in the car with damp clothing. It seems to forestall the time when I'll actually need to defog the windows (which otherwise occurs very quickly if I have damp clothing on a rainy day).

Most modern cars automatically engage the A/C when you turn on the defroster. They do that for two reasons: one is to dry the air, the other is to circulate lubricant through your A/C plumbing. Your A/C system will be happier if you allow it to run every so often, even in the winter. So if you're manually turning off the A/C after you hit the defrost button, you might be shooting yourself in the foot in two different ways. I try to let the A/C run for at least two minutes every month in the winter, in order to keep the various rubber seals from drying out. Winter time use of the defogger usually makes this regimen almost automatic.


But with all that said, there is a fair amount of discussion in the owner's manual about how to respond to interior fogging problems. Enough discussion in fact that it kind of has a "bad smell". Sort of like when some product is "new and improved" and claims to no longer have "problem X" and you notice that it actually now has "problem X" when it never did before? As a wild guess: something about the Niro's fan-off ventilation system might be different, perhaps for fuel economy reasons. Maybe it's about the way the air-intakes are configured in proximity to the hood, or maybe it's kind of like modern aircraft that have discovered they could boost fuel efficiency by reducing the rate at which they allow external fresh air into the cabin. Although in the case of aircraft, they have to spend energy pressurizing any air they introduce, and that's not a requirement for a Niro.

Bottom line: try cracking your window until the ICE is warm enough to let the climate system blow heat, and try letting the A/C run, even in cold weather, if the defog button turned it on. And if those ideas fail, maybe go back and read the manual's discussion on the interior fogging topic. I don't trust my memory enough to confidently quote back everything I read about that a few months ago.

I'm getting the same thing. For me, its not just the windshield... every windshield has some interior frost. I've tried the moisture absorb stuff and not much use. I ask T.O. Kia to have a look a few weeks ago when it was in for factory recall stuff... they couldn't find it... or didn't bother to look. I do what I can to knock off as much snow off my boots... still same thing. ensure the bottom of the windshield is cleared of snow... comes back.

I too get the windshield fluid smell when I spray the windshield... maybe that is what it is...???

If anyone figures it out... please post their solution...

If you try not leaving the heating position on the defrost position. will it work ?

I called my local Lockwood Kia dealer and explained what it was doing and they gave the same shpeel about moisture inside the car and that it is common in all cars. The down side of trying to take the car to a dealership is you will need to defrost the car to be able to drive it to them so you are solving the problem before they get it. I happen to have my wifes car in for bodywork after some nimrod decided to drive between two lanes at a stoplight and take off (thank goodness for dash cams), so the car is at their bodywork facility for a week. Told them to take a better look at it as well as the smell with the washer fluid as I think the two might be connected.

Frost on the inside of the windshield is a major problem here in upstate NY where it often gets below zero..............there are several reasons for this, NONE of which are the fault of Kia or Niro...............


I added rubber floor mats with deeps ridges and wells to catch water from slush, snow, melted snow etc..........this adds MOISTURE in the vehicle atmosphere which WILL make it's way to the windshield and frost/freeze, (even if you have only carpeted floor mats)............... bear with me THERE IS A FIX


I tried DAMP RID, no luck, I tried applying RAIN X, NO luck,,,,,,,,,,,,,I have READ but NOT tried, adding cat litter to a sock and leaving on dash board to absorb extra moisture (didn't want to do this for many reasons but I have read good results for some people)


What I do know DOES work,,,,,,,,,,,,,,leave front windows open just a tiny hairline and the outside air will help dry any cabin moisture...........I tried it and whalloa! No more interior frost ANYWHERE

If you look at the climate control system as a whole. when the system is running it is bringing in fresh air from outside and running it through a heat transfer system and pushing it into the cabin. Likewise, there is an air return system that vents the air from inside the cabin back to the outside. If you select the recycle option on the dash, the return air gets redirected to the incoming air flow over the heat transfer system and in theory will warm up faster than if it was brought in from the outside, but at the expense of your not getting fresh air from outside so whatever is in the inside air stays inside. The Niro has an AUTO selection that will move the air flow around the car in order to best heat/cool based on its own algorithm. Also, the car has automatic defog where it has a sensor on the top of the windshield to detect moisture and force the air to be routed to the front and side windshields as well it kicks off the recycle function.


If you are running any climate control, and have not been forcing recycle on at every opportunity, then the car will be refreshing the air inside the car with new air from outside, much like leaving your window open a crack as you drive. So the car should be replacing the moist air from your breathing along with the extra moisture from what is kicked off from snow on your feet/clothing during a reasonable length drive in the car. Compared to many other cars, it seems the Niro doesn't do a very good job of moving enough air or the air it is bringing in is routing through an area that is prone to picking up moisture that other vehicles do not. This last point might be the case as it is clearly shown when you run the windshield washer and you get a strong smell of washer fluid. that smell is not coming through the windshield but from the venting system. So there must be an air in port right around the front bottom of the windshield. As you defrost the windshield, any moisture from snow/ice will run down to the bottom and collect. It is impossible in the winter time when you clear the windshield of snow to remove all snow and ice from the bottom part below where the wiper blades rest. There is a black plastic bit that runs between the windshield/body and the hood over the engine compartment. That part will be warmed up by the heat inside the engine and the heat from defrosting the windshield. On my wife's 2006 Kia Sportage, even the front windshield has an electric heating element that ran the full length of the bottom of the windshield to help keep the windshield wiper blades warm so that ice would not form on them and make them work better. I don't know enough about the Niro to know if it has this feature as well, but it wouldn't surprise me if it did. So if that is also where the Niro gets it fresh outside air from, that air will be extra moist from running over this warmed wet patch. So I would say it is the NIRO's fault that there is way too much ice in the windshield in a very cold morning as by it's bad design they are making the matter far worse than it needs to be.

If you try it, place the sock under my seat on the floor.! ;)

@Roadkill401 : Do you think that it could be the "climate control air filter" that can cause this problem ? found this in the manual with the "Auto defogging system" option. I will try this later on tonight! Ohh another thing, one of my contact at the dealer told me yesterday night that it's not considered to use the "auto" button when it'soooo cold outside ! He says that it's useless to use and is mode for mild and warm temparatures.

Cracking the window works on all cars including the Niro. I will say the Niro fogs and frosts easier than other cars I have owned. I wonder if that is because the windshield is less vertical than any other car I've owned.

Cracking ? you mean give it a "gap" open ?



I had the same problem with my 2013 Rio5 and my wife with her Hyundai 2014 Accent...

We do crack windows... however, I'm not sure they do in all of Quebec. It doesn't translate well in french.

Yes, we do some times make an "overture" of our windows...! ;)
For me a "gap" is an overture.. small gap (1-2 inch) opening of the window.. anyway.. crack, gap, overture, opening, etc... same thing ... >:)




@Congee, hahaha.!! you're a very funny person.! ;)
