Most wipers seem to stop about an inch away from the A-pillars. That's why I said it is important to ensure that the wipers don't hit the A-pillar if you're going to adjust them. After all, that inch might be all it takes to prevent the OP's issue.

Re: Design Flaw - wipers freeze up when driving in cold, wet conditions

I actually got mine to randomly freeze in our last storm. I noticed a rather odd pattern of what was melting and what wasnt on the windshield with the defroster blasting. I'm wondering if the laminated glass has issues with heat transfer.

Any way it wasn't a big deal... wasn't the first car that this happened to me with

Re: Design Flaw - wipers freeze up when driving in cold, wet conditions

Hey, guess what happened again this morning. Repeatedly. I had to pull over three times on my 15 mile 35 mph commute to scrape the ice from the wiper resting place. Each time there was a good 1/4" of ice surrounding the wiper blades, and the blades were frozen to the glass. Before driving I cleared every bit of snow from the car, paying special attention to the wiper blade area. There was no snow left there whatsoever. I did not use the washer fluid at all; it can't be blamed. This is simply a design flaw - the wipers rest in an unheated area and they freeze to the glass in cold, wet conditions.

While it's an interesting idea, I don't think re-indexing the wipers will work. This morning I watched how close they come to the A-pillar - about 1/2". There's no room for re-indexing.

Re: Design Flaw - wipers freeze up when driving in cold, wet conditions

I was expecting more of a problem in the snow we've had here the last couple days, but I really haven't had any issues. I can see how it would be a problem though.

Still, I don't know I'd call it a "design flaw." Something they overlooked, surely. But I don't know about a flaw. They did put a heater strip on the rear winder for that wiper, I'm surprised they didn't think to do that for the windshield- it is quite the oversight.

If it turns out this issue is problem for most people, it would be an easy fix for Jeep. They could easily put heater lines at the base of the windshield. Or they could raise the parked position of the wipers and reduce the swept range of the driver's side wiper to prevent contact with the A-pillar.

But still, this is the sort of thing that should have been caught during cold weather road testing, during the development of the WK2. It's the little things that are often overlooked until actual owners start complaining about them. It will be interesting to see if they make any design changes in the near future. I'm not sure how many people are complaining about freezing wipers though...

If it's this bad and you consider it a genuine safety issue, you can file a report at https://www-odi.nhtsa.dot.gov/ivoq/

Re: Design Flaw - wipers freeze up when driving in cold, wet conditions

I want to chime on this issue as well.

There is definitely something abnormal about the wiper configuration, at least compared to my previous vehicles. As a native New Englander (VT and MA) I'm accustomed to the crummy winter conditions and wiper freezing. Yes, it happens.

However, I'm definitely experiening the *worst* winter wiper performance of any vehicle I have ever owned, and I've owned some real garbage. I'm not sure what it is, but I literally had to bang the ice off my wipers 5 times on the way to work this morning...never before have I had them build up ice on the blades so quickly.

It was funny, I passenger side was so bad it looked like size of a man's arm covered with snow going back and forth over the windshield.

I was truly amazed at how quickly the blades become useless with some freezing conditions and precipitation.

I'm not trying to complain, I have no problem buying a different blade if that's the fix, but no vehicle I have ever owned absolutely required switching to a winter blade in the winter. I don't get why people are flaming the OP for bringing this up, people are entitled (welcomed I thought) to discuss their issues, especially ones that have safety considerations.

The real question is: Will switching blades fix the problem? I guess I'll find out and report back.

It sounds like less of a wiper blade issue and more of an issue with where the blade sits in the parked position. Glass is a good conductor of heat, so a heated windshield will usually prevent (or at least delay) the wipers freezing in bad weather.

Why shouldn't you complain? If we don't complain no problems will ever get fixed.

I completely agree with this. Fanboyism is not beneficial for anybody, including fanboys themselves (ironically). You can hate other brands all you want, Toyota (for example) is not the one who required bailout (even though it does have its own problems)

Re: Design Flaw - wipers freeze up when driving in cold, wet conditions

I'm glad to hear others are experiencing this. (Well, not really, but you know what I mean.) I think the problem is twofold - (1) the wipers rest in a completely unheated area at the bottom of the windshield, below where the dash is touching the glass, and (2) the windshield defroster on this car is just plain awful. I have to keep it in the defrost setting on at least "four bars of blow" non-stop or else I get icing on the top half of the glass. This is even when it's not that cold out, like 28F. I've never had a car where I couldn't leave the defroster on the lowest fan setting once the glass was defrosted.

I think the heating in this car in general is quite poor. It just doesn't seem tog get very warm. The footwell, in particular, doesn't heat up. Typically, in other cars, I set it to bi-level defrost and feet, and the whole car becomes comfortable. In the WK2, this setting leaves the feet cold and the mid-body area colder. If I set it to blow from the vents towards the passengers, the windshield frosts up. I can't win.

It's a shame, I really like the car. But the HVAC is very lackluster. Is this Jeep's first attempt at climate control? My KJ with simple non-programmable knobs was always hot and cozy.

I know I went off on a tangent, but my point was that the wipers freezing is a single symptom of the underlying cause - the entire heating system fails to deliver.

Well its definitely not the first Jeep's attempt at climate control - my '98 ZJ had it and this model was in production since 1993 (or 92)

I think your complaint is perfectly valid. I would be pissed if I experienced this. However, I just don't drive all that much and didn't have a chance to drive new Jeep in this kind of weather. Mostly I would just defrost windshield and then wouldn't need wipers anymore because it was not snowing.

I don't think I experience what you described about poor heating system in general.

Just another reason why you NEVER BUY a first model year of ANY CAR. EVER.
