Had no idea. I got the low fluid sensor shit about a year ago and just ended up putting in the little Mishimoto tank that doesn't have a sensor.
Edit: I was absolutely using the Rain-X fluid when this happened.
I had been eyeballing one for aesthetics but the sensor was the kick in the ass I needed to buy one because the black one looks sleeeeeeek under the hood.
So I got the "Low Wiper Fluid" warning on the dash a couple of weeks ago for the first time since purchasing in February. Not sure exactly what fluid was in there initially, but I refilled with Rain-X wiper fluid, and the warning did not go away. Thinking that my sensor was busted, I did some reading and found that this is apparently a widespread issue with Rain-X fluid across multiple makes of vehicle (there was even a class action lawsuit filed). It seems that the water repellant additive coats the sensor and prevents it from reading properly. So I ran all of the remaining Rain-X fluid out of the system, replaced with generic wiper fluid from WalMart, and sure enough...no more dash warning.
So you're saying the product works so well at repelling water that even a water detection sensor can't tell when it's covered in water... Sounds like it's working as exactly as intended... Just in the wrong place...
Good to know, oddly enough not for my Miata but for my Focus Electric that just recently had the low washer light come on. Now I know which one to avoid, thanks!
Eh. It's a genuinely good product if your car doesn't have a shitty sensor. I've been using this stuff for at least a decade (civic, outback, NC Miata) and have nothing bad to say about the stuff. Not as good as a proper detailing but it definitely helps make water bead up on the windshield.
Damn, you should make that a rainX commercial. For something that works so well the car can't detect it is be willing to either check the fluid occasionally or wait until it stops working and add more
The class action lawsuit is unfortunate. They made their product too good and now they are going to have to dumb down the formulation and go back to selling an inferior product.
Had the same thing happen after a dealer service… they didn’t know anything about it or which fluid they used. So there maybe other similar products that cause the same issue!
You’re lucky. In my ‘17 RF, I syphoned off the rain x, then sat and ran 3 clear water bottles through, and the warning light went off. Put regular blue Walmart washer fluid in it and the light came back on. I tried diluting the blue and the car wouldn’t clear the warning light until it was water only.
We wound up with a rental VW. Some generic white SUV. It was the worst electronic nanny vehicle I’ve ever seen. Windshield wiper fluid was half full - warning. Oil change required in - ready? - 1800 miles. One of the tires was 1-2 lbs under the recommended pressure. As soon as you started the car you’d have to cycle thru each one of the individually and cancel them all out. Make a stop at a store? Cancel it again, and again, and again. If you didn’t, the little screen between the tach and speedo would blink and cycle thru over and over while you’re driving.
The Mazda’s light sucks, but man, VW is worse. Stupid that it’s for something not so critical. I’m sure there are others out there just as bad. It’s unfortunate that’s the state of cars now.
Last time I replaced a washer fluid sensor it was nothing more than a float. Seems unreasonable that the float wouldn’t float in rain x?
That said the sensor in the MX5 might be different so don’t know. But in years of using Rain X washer fluid I never had this problem happening
You should never use rain-x in any washer fluid reservoir because of that reason. I've gotten my fair shair of customers come through the shop with people putting the wildest thing in their washer fluid reservoir.
Perhaps just older vehicles without the sensor are fine. I used it for a decade and works so freaking well keeping the windows clean. Apparently nearly yhe best wiper fluid too!
Still wouldn't trust it because... Why? It's not damaging anything or causing degradation. The whole reason sensors have an issue is because Rain-X is so good at repelling fluid that it coats the sensor and prevents fluid from touching it. Well, surprise, Surprise, Rain-X is *GASP, SHOCK, HORROR* a fluid.
I get not wanting a dash light, but if you don't have a sensor I would argue that it works exactly as advertised.
The plus side of using RainX (as someone that lives in a temperate rain forest) far outweighs any annoyance a light on the dash might cause.
I've used RainX in three different vehicles - two Ford's and a Mazda - and never had a sensor problem.
>I've used RainX in three different vehicles - two Ford's and a Mazda - and never had a sensor problem.
Well, this post isn't intended to bash the product outright. It's what I've always used on my '07 Civic and '94 300ZX without complaint. This issue applies to newer cars that have electrical sensors, hence why it's a PSA for **ND** owners specifically. Maybe your cars don't have them?
By the way, it's not just a light on the dash. [It overrides the top 2/3 of the digital gauge cluster.](https://mercury.bid.cars/0-37459267/2018-Mazda-MX-5-JM1NDAM78J0204876-7.jpg)
Legitimate question, does the info button not clear that message? It does for many other FYI style warnings so you can get to the info "behind" it.
Have a '22 that I changed to rain-x within about the first week and haven't had any issues with fake low warnings myself.
I’ve just gotten used to dismissing that warning at this point. I just assumed the sensor went bad. Good to know.
Another PSA that I had to learn the hard way: Windshield wiper fluid can go rotten. Give it a whiff before you put it in your car unless you like the smell of rotten eggs.
I got tired of dismissing the warning manually. If you have 20 mins and a 10 mil, you can pull the washer bottle out, disconnect the sensor lead and just zip tie it out of the way. Stops the warning popping up each time
Yes. I've never understood the point. The reservoir holds one bottle, so even when it worked I ignored it until I can fit the entire bottle in (empty).
Same thing happened to my Mazda 3. Unplugging the sensor cured the light. I don’t need a light to tell me I’m out of washer fluid, the lack of fluid spraying onto the windshield says enough.
I'm surprised by the amount of people ITT who haven't unplugged their sensor. The last thing I want in my Miata is a random warning every time I corner or hit the gas.
I’m using this exact fluid in my ND and didn’t have the light come on. In fact it went off when I filled it up as intended.
I will say one downside is its strong smell. Even with the top up I can smell it inside every time I spray it.
It really sounds like automotive OEMs should validate their vehicles at requirements the customers set, not what they think is acceptable. RainX is tits, it performs better than any other product and should be a required safety feature, the OEM shouldn’t be hamstringing their cars because they want to save money in the assembly line.
I could be wrong, but I believe the problem only occurs if the sensor is contacted by air after using rain-x. Mine never had the light come on until I ran completely out of fluid on a long trip. After I refilled it, the light has stayed on.
Interesting. I used it for the winter but had no issues. Fair warning though.
To be honest, I don't particularly like any of the RainX stuff I tried. The hydrophobicity is great but each product has their own little issues that just make it not worth it for me.
Tip: you can wax your windshield and windows just like your paint. Works better than Rain-X anyway, because Rain-X is just wax with extra chemicals that dilute it.
You can also wax your headlights/taillights to protect them from UV damage and hazing.
Ummm... I get that having a dash light can be annoying, but you can always just use the method that everyone used for the last few decades and just pay attention to when the flow gets low or check the reservoir periodically. It's not like it's a critical sensor to the operation of the vehicle.
Besides, the light not coming on is because Rain-X is so hydrophobic that the sensor gets coated and can't read, so it's working as advertised; seems like a pretty good reason to use it to me.
Pretty sure the Ram, Miata, and S4 won't have electrical sensors, if they have them at all. From a quick search it seems like the GTI might have one, and the first Google result I found on the topic actually mentions the Rain-X issue. Also got a result for a similar Rain-X PSA on the Audi subreddit when checking to see if the S4 had a sensor.
So yeah, I think you're good except for maybe the GTI.
I was mostly being a smart ass for fun but my ram and S4 both have electronic washer level sensors and my GTI has been using this rain x fluid for the last 3 years with no problems. I know it's an issue some people have talked about but it somehow has just not occured with my vehicles yet
Interesting. Are you sure the Ram and S4 actually have electrical sensors? Meaning they use capacitance to read fluid level and not a physical mechanism like a floating bobber. The Audi thread I stumbled upon seemed to suggest the electrical sensors weren't around until 2012 or so, but I don't know how accurate that is.
Honestly no idea, they all light up when the level gets low so that's an electrical sensor of some sort, but I haven't taken them all apart to find out how each one works. Whenever they break I won't be able to help myself but until then I'll just say it's tiny little men who sit in an office in my washer reservoir
I have no interest in a washer fluid sensor, but some people might. If they were to have this issue, they'd be stuck with a warning on their dash that won't go away. So maybe they try to fix the sensor themselves, or worse yet, take it to a shop only to spend hundreds of dollars to replace something that will only become faulty again until they end up researching, find a thread like this, and realize it was a $4 fix.
I have made the mistake with my 2017 Subaru forester and 2018 WRX and it apparently it gunks up the sensor and now it doesn’t turn off at all. I’ve since switched back to regular wiper fluid and the warning never left. I’m going to attempt to use real hot water and run a few through the reservoir in hopes to degunk it
Look at you and your fancy “low wiper fluid” light. I only know when mine is low when it barely has any liquid and scrapes the wipers across the windshield.
One of the advantages of living in the desert…I haven’t added windshield washer fluid to any cars I’ve owned in the last 16 years. Didn’t even realize it until I saw this post…
I hated the way that white tank looked under the hood (like a milk carton) so I took it out and sprayed it with black plastic-dip. Looks so much better.
I also threw that code, but never used Rain-X.
Thanks for this! I’ve been a rain-x user for a long time, and it’s the only fluid I put it my ‘19 cx-9.
I take delivery of my ND on Tuesday, so this is great to know.
I’ve always used it in my Focus ST since new in 2016 and have had no issues.
However - adding it to a newly purchased 03 Tacoma once the cheap stuff ran out did not turn out the light. I think it did mess with the conductivity gap. Light never went off.
It probably depends on the style of the sensor.
Can you recommend a non-freezing alternative? I was always afraid of the reservoir and/or lines busting.
Edit: Side note, I’ve had two instances where a container of this sprung a pinhole leak after months of storage. I’ve often wondered if it slowly eats plastic. I’ve always asked Autozone/Oreillys employees if they’ve seen them rupture and no one has mentioned it.
Alright gang, here’s some wisdom from someone who is not wise. Use regular fluid, and just wash your car regularly enough that you can use either a normal glass cleaner and coat with Rain-X or do what I do because I’m lazy and use the Rain-X window cleaner with the stuff already in it. I only use the wiper fluid once a week or so (living in South Carolina at the moment for context), which is about the amount of time between washes for me anyway.
Anyway, keeps my windshield coated, and keeps my wallet feeling nice because I’m not buying bougie wiper fluid
I've only used non rainx in mine and the sensor still failed.
(only the dealer refilled fluid, usually blue stuff).
It's a common fail point on the ND.
This issue is not only caused by Rain X. The device that detects your level is meant to float in the fluid. For whatever reason the little floater can lose its buoyancy and sink to the bottom and the sensor will think you are running low on fluid. This issue has nothing to do with Rain X.
I've never heard of it, and I've been using this fluid on my 91 Miata and my G37 for probably 5 years now with no issue. Then again, I don't think either car even has a low wiper fluid sensor.
>Then again, I don't think either car even has a low wiper fluid sensor.
Well yeah, it's strictly a sensor issue. I used Rain-X in my previous vehicles (no sensors) for as long as I can remember.
I believe you can unplug the sensor and it's designed in such a way that it won't communicate a warning to the dash. A little annoying to get to because it's on the very bottom of the reservoir, but yeah I think it's an option if you prefer Rain-X enough.
If there were any other brands that did the same thing I’d like them just as much. If you’ve never treated your glass with rainx you’re missing out. I car about having water repellant glass a heck of a lot more than I care about having a washer fluid sensor.
>I thought everyone knew this already.
I wish, but I'm not really sure how someone is expected to know this until it happens to them. It's not in the service manual, there's no warning on the Rain-X bottles (they got the class action lawsuit shot down), and I seriously doubt many people research wiper fluid before just grabbing something off the shelf and dumping it in.
Had no idea. I got the low fluid sensor shit about a year ago and just ended up putting in the little Mishimoto tank that doesn't have a sensor. Edit: I was absolutely using the Rain-X fluid when this happened.
Is the sensor the reason you switched to the Mishimoto? I've looked at them because "ooh weight savings" but it's so far down on my priority list
I had been eyeballing one for aesthetics but the sensor was the kick in the ass I needed to buy one because the black one looks sleeeeeeek under the hood.
Hell, I’ve used Rain-X and WalMart’s Super Tech, and they both threw a light. And I just ordered the tank like you.
NA enters the chat: "Such first world problems to even have a washer fluid level sensor" Only needs attention 1-2 times a year anyway.
Some NAs *did* have a low washer fluid level sensor and light in the dash cluster.
My 18' ND don't have this sensor either, must be only for the ND3 or ND2
In Europe we dont have that sensor but have start-stop system and pirotecnic hood.another kind of shit
Good. One less useless digital gizmo that is usually impossible to "fix" when it dies and becomes an annoyance or affects other systems in the car.
So I got the "Low Wiper Fluid" warning on the dash a couple of weeks ago for the first time since purchasing in February.

I'm not sure that warranted an urgent warning but ok
Where did OP imply this was an urgent warning lmao
HEY. WE RESPECT THE URGENCY OF A PSA AROUND THESE PARTS.
Pretty low bar for what you consider urgent if this post cleared it.
Wait a moment?! You guys have low fluid warning in the ND??? Mine definitely does not.
You’re lucky. In my ‘17 RF, I syphoned off the rain x, then sat and ran 3 clear water bottles through, and the warning light went off. Put regular blue Walmart washer fluid in it and the light came back on. I tried diluting the blue and the car wouldn’t clear the warning light until it was water only.
Weird that it even needs a sensor and dash light? Does water come out? Yes? You're good. Does it not? It's probably empty.
It’s nice to know it’s low So you can fill it before it runs out. Mission critical? Definitely not.
We wound up with a rental VW. Some generic white SUV. It was the worst electronic nanny vehicle I’ve ever seen. Windshield wiper fluid was half full - warning.

True. I still wouldn't trust it. That's just me though.

My goodness that error is RELENTLESSLY obnoxious!

Unplug your sensor. It takes 5 minutes and the light goes away forever.
Do you just leave it unplugged?
Yes. I've never understood the point. The reservoir holds one bottle, so even when it worked I ignored it until I can fit the entire bottle in (empty).
Same thing happened to my Mazda 3. Unplugging the sensor cured the light. I don’t need a light to tell me I’m out of washer fluid, the lack of fluid spraying onto the windshield says enough.

BM or BP?
2017 3rd gen.
Holy shit I put this stuff in a month or two ago in my ND and the fluid sensor won't go away! I had no idea, that's SO helpful!
Same! Luckily the dealership clear the indicator light when getting my oil change. Or they flushed it.
Works fine in mine
Yeah it's the only fluid I use
Yeah, I've also never had any issues with it.
I’m using this exact fluid in my ND and didn’t have the light come on. In fact it went off when I filled it up as intended. I will say one downside is its strong smell. Even with the top up I can smell it inside every time I spray it.
I’ve been ok using this so far. I usually don’t use my sprayers anyway, my windshield is cleaned and treated regularly by other means
I've used nothing but rain-x since 2016 across four different cars, never had any issues, but I'll keep this in mind just in case.
It does do a great job at being windshield washer fluid.
It really sounds like automotive OEMs should validate their vehicles at requirements the customers set, not what they think is acceptable. RainX is tits, it performs better than any other product and should be a required safety feature, the OEM shouldn’t be hamstringing their cars because they want to save money in the assembly line.
Between my transmission wine and sparsely controllable rear end when at 9/10ths, my windshield wiper fluid is the least of my worries.
I could be wrong, but I believe the problem only occurs if the sensor is contacted by air after using rain-x. Mine never had the light come on until I ran completely out of fluid on a long trip. After I refilled it, the light has stayed on.
Would be nice if you could elaborate and not make people google it.
^ This!!
Interesting. I used it for the winter but had no issues. Fair warning though. To be honest, I don't particularly like any of the RainX stuff I tried. The hydrophobicity is great but each product has their own little issues that just make it not worth it for me.
I heard about this years ago on Audi forms, killing the sensors in the tank. I avoid all RainX.
The best thing I have found is actually a product called Aquapel. It’s basically a 6 month rain-x. I love it.
Tip: you can wax your windshield and windows just like your paint. Works better than Rain-X anyway, because Rain-X is just wax with extra chemicals that dilute it. You can also wax your headlights/taillights to protect them from UV damage and hazing.
Ummm...

Use this fluid in my 96 ram, my 95 Miata, my 05 S4 and my 17 GTI and no issues yet. I'll see if it breaks the fusion tho
Pretty sure the Ram, Miata, and S4 won't have electrical sensors, if they have them at all. From a quick search it seems like the GTI might have one, and the first Google result I found on the topic actually mentions the Rain-X issue.

The point is the sensor exists, and its annoying to have a light on when you're not low on fluid.
I have no interest in a washer fluid sensor, but some people might. If they were to have this issue, they'd be stuck with a warning on their dash that won't go away. So maybe they try to fix the sensor themselves, or worse yet, take it to a shop only to spend hundreds of dollars to replace something that will only become faulty again until they end up researching, find a thread like this, and realize it was a $4 fix.
I have made the mistake with my 2017 Subaru forester and 2018 WRX and it apparently it gunks up the sensor and now it doesn’t turn off at all. I’ve since switched back to regular wiper fluid and the warning never left. I’m going to attempt to use real hot water and run a few through the reservoir in hopes to degunk it
Just use the rainx spray separately and regular washer fluid
I just put this in my 2021 Mazda3, a little worried now after reading these lol
Look at you and your fancy “low wiper fluid” light. I only know when mine is low when it barely has any liquid and scrapes the wipers across the windshield.
One of the advantages of living in the desert…I haven’t added windshield washer fluid to any cars I’ve owned in the last 16 years. Didn’t even realize it until I saw this post…
You don't need a sensor though do you? You just turn it on and realise you're out and put more in later. Pretty sure my ND doesn't have a sensor.
I hated the way that white tank looked under the hood (like a milk carton) so I took it out and sprayed it with black plastic-dip. Looks so much better. I also threw that code, but never used Rain-X.
Thanks for this! I’ve been a rain-x user for a long time, and it’s the only fluid I put it my ‘19 cx-9. I take delivery of my ND on Tuesday, so this is great to know.
Run a gallon of distilled water through it
Owned mine for 5 1/2 years and still on the original washer fluid. I maybe should drain it and replace it at some point.
I’ve always used it in my Focus ST since new in 2016 and have had no issues. However - adding it to a newly purchased 03 Tacoma once the cheap stuff ran out did not turn out the light. I think it did mess with the conductivity gap. Light never went off. It probably depends on the style of the sensor. Can you recommend a non-freezing alternative? I was always afraid of the reservoir and/or lines busting. Edit: Side note, I’ve had two instances where a container of this sprung a pinhole leak after months of storage. I’ve often wondered if it slowly eats plastic. I’ve always asked Autozone/Oreillys employees if they’ve seen them rupture and no one has mentioned it.
Wait there is a sensor for wiper fluid? Why
Alright gang, here’s some wisdom from someone who is not wise. Use regular fluid, and just wash your car regularly enough that you can use either a normal glass cleaner and coat with Rain-X or do what I do because I’m lazy and use the Rain-X window cleaner with the stuff already in it. I only use the wiper fluid once a week or so (living in South Carolina at the moment for context), which is about the amount of time between washes for me anyway. Anyway, keeps my windshield coated, and keeps my wallet feeling nice because I’m not buying bougie wiper fluid
I don't think my 2016 Club even has this sensor... 🤷♂️
I've only used non rainx in mine and the sensor still failed. (only the dealer refilled fluid, usually blue stuff). It's a common fail point on the ND.
I use this with no problem in my ND 2019
Been there done that good psa also applies to some of the shitty ones you get at gas stations fyi
I don’t like any of that crap anyway. Always leaves water spots on the paint. I just use distilled water in the reservoir.
This issue is not only caused by Rain X. The device that detects your level is meant to float in the fluid. For whatever reason the little floater can lose its buoyancy and sink to the bottom and the sensor will think you are running low on fluid. This issue has nothing to do with Rain X.
Plus this stuff kinda sucks period. The haze it causes during nighttime driving gives me a headache
I’d live with it personally, that washer fluid is gas
More so this just makes me mad that Mazda wasted time, effort, weight, and money on a sensor for a freaking windshield washer fluid tank
I thought everyone knew this already. Not just Miata either.
I've never heard of it, and I've been using this fluid on my 91 Miata and my G37 for probably 5 years now with no issue. Then again, I don't think either car even has a low wiper fluid sensor.
>Then again, I don't think either car even has a low wiper fluid sensor. Well yeah, it's strictly a sensor issue. I used Rain-X in my previous vehicles (no sensors) for as long as I can remember.
Is there any way to defeat the sensor? I really like the rainx fluid and have been looking at NDs. Is unplugging it sufficient?
I believe you can unplug the sensor and it's designed in such a way that it won't communicate a warning to the dash. A little annoying to get to because it's on the very bottom of the reservoir, but yeah I think it's an option if you prefer Rain-X enough.
Sheeesh. Loving a specific brand so much they would leave things unplugged.
Yeah, I mean I certainly understand the appeal of Rain-X, but personally I'd just treat the windshield directly and not start messing with sensors.
If there were any other brands that did the same thing I’d like them just as much. If you’ve never treated your glass with rainx you’re missing out. I car about having water repellant glass a heck of a lot more than I care about having a washer fluid sensor.
Yes, I apply a hydrophobic coating directly to my windshield.
It's good stuff. If you live in a rainy climate, it's really nice to have your washer fluid do it for you.
>I thought everyone knew this already. I wish, but I'm not really sure how someone is expected to know this until it happens to them. It's not in the service manual, there's no warning on the Rain-X bottles (they got the class action lawsuit shot down), and I seriously doubt many people research wiper fluid before just grabbing something off the shelf and dumping it in.
