Picked up new 2017 JK half door late April. First time in rain, driver's floor soaked and passenger floor very wet. Water streaming in at mid door over plastic sill. Major leak, pulled up carpet and standing water in tub. Been at dealers for two weeks. Still leaks. They dunno what to do! Taking it to a Ford dealer to have a Water Doctor look at it! WTF! Suggestions?

Find a new Jeep dealer. It shouldn't take two weeks.

By "plastic sill", do you mean you have the optional plastic door sill guards in place with 'jeep' stamped in them?
I'd start by checking the door seal in that area for tears or improper installation of the seal itself at the factory

Also, try removing the sill guard and seeing if that remedies the problem. Sometimes there can be a gap after putting in the guards.

Remember to pull the floor plugs to let the water drain until you get it fixed.

Amazing.. We picked up our half door unlimited about the same time you did. Slight drips along & around the tops of the doors. We've driven through heavy rain and sat in the jeep during heavy rain. Only thing one should try is to re-seat everything in the jeep. This would mean removing all the half door uppers, side windows.

Then reinstalling them once again. Make sure when you reinstall the half door uppers, Set these back in hard so that they bottom out or mate up with the metal lower doors. If off kilter, these may not line up correctly. However, We have noticed that the second row passenger door's rubber seal (towards the top right corner) doesn't seat correctly when the door is shut. but still no drips or leaks.

One would tell you with half door or even all fabric doors.. leaking would be the norm.. not the case (knock on wood) in our case.

Edit:

Wanted to add one more procure to the list of removing and reinstalling soft products.. Check the front seal of your soft top where this mates up with the windshield. If you have the sunrider or other soft top.. again open, clean or check to see if there's a main seal in that location.

make sure whoever your dealership takes it to, follows the Jeep repair manual and uses MOPAR-OEM materials and parts.

otherwise you'll get crap like this (see photos) from a "Water Doctor". under no circumstances let them stick on home depot door seals that you buy on a roll for your house doors and garage door. if it's not MOPAR and if it's not following the Jeep repair manual, it doesn't belong on your Jeep while it's in warranty. reason being, if you move somewhere else and it starts leaking again, the new dealership could accuse you of voiding your warranty with modified seals and weather stripping. they would also contact Chrysler with photos and inform them that it appears someone did DIY work on it. unless you have photos and a very detailed description from the dealer who did the aftermarket water leak crap, you're screwed.

my 2017 Jeep bought in October with 4,100 miles is at a 3rd dealer trying to fix my A-pillar water leaks. days out of service is now 36 and this is repair attempt #3. i already have a new Jeep order placed and plan to switch to that one and dealer said they would take care of everything

oh and welcome to the water leak club.

Find another Jeep dealer and have them look at it if your current one is truly lost and trying to farm it out to a different brand. That's just........weird. I had my 2012 in starting in December for what took about 3-4 months of free followups usually 1-2 days max at a time after their initially having it for over a week in December replacing a bunch of seals and proclaiming it good. Their final step was to get a Chrysler leak specialist out who finally did find and fix the problem after another week and a half of it being in the shop. It's basically a tech from Jeep that all they do is go around to dealers and work on leaking tops, but it's a "last resort" usually. FWIW I had no leaking problems for the first couple years, then I think some of the foam on the freedom panels started degrading and the first dealer I went to screwed everything up with jerry rigged fixes and made it worse.

My 3-year old is leaking now over the passenger interior handle. Haven't had this much water swamping with it.
Time to look into it.
 
#13 ·
If it's directly over it that's either the foam on the freedom panel is rotted out, a pillar mucket is either worn out or got rolled over last time the panel was put back, or the door seal is going. Not a lot else right there except maybe the header is plugged and not draining right.

Had this issue in our 2011 Wrangler JK unlimited. After three years and 40k miles and multiple trips the water leak was so bad my carpets got moldy and water was going behind the dash shorting out the radio. Jeep finally decided to buy it back. The one dealer finally admitted that there was a major problem that couldn't be fixed because they didn't know how or why. Had multiple problems with this Jeep, not just this leak, but some I hear are not fixable.

That is sooo much easier than letting my dealer have a shot at it.

I did check a new JK at the dealer and it looks like a 6mm closed cell foam like soundproofer/heat shield. I have some in transit for my front wheel wells.

Mine was completely compressed. Not bad for SoFlo and outdoors 24/7.

Wheeled deep water on Sunday, but the carpet got wet from the leak during a downpour.

Taking it to the dealer for the factory/dealer re-store. Looks like the foam pads need to be replaced after three years of Florida heat.

Wonder if my extended warranty covers this?:winner:

I have the same problem, but on the passenger side. I took it back to the dealership multiple times, but they can't replicate it in the car wash. I have learned to accept it since it is a lease, but if I had purchased it, I would go further with it. I am hoping the next one won't do that.

So my dealership uses an outside contractor to do the work. He does the warranty work for the shop and bills them almost $400 for the warranty work Chrysler pays for.

Well mine isn't under warranty and he charged me directly $180 and basically rebuilds the foam and rubber gaskets with non-Mopar parts.

I'll take a pic or two when I get a chance.

No rain last night so no report.

I was able to ever so slightly adjust my door hinges and latch so that the door sits a little tighter (1 mm'ish). This helped to create a better seal

Additionally I purchased the derlin door bushings so that the door would sit about 1mm higher.

This worked for my situation (with front half doors.

Mine started leaking ,water on passenger side under carpet .
Dearattleler replaced door seal ,still leaks after sitting in the rain all night.
I amd the going to a different dealer on monday morning and hope for the best.

My jeep had no leaks for the last 14 months since new, but i went in for a rattle fix.
After 3 days at the dealer got jeep back and they had to adjust rear tail gate latch and that
fixed the rattle.I don't know what else they did before finding the rattle but my jeep has been leaking ever since.

:winner::winner::winner:Sorry for the typo errors.
I also suspect bad door adjustment on the new rubber seal around the door.
If i pour 3 inch of water from a small pail on the soft top over the passenger door
I look inside from the driver side and can see the water flowing down the last 12 inch of the door on to the plastic cover and then on the rubber mat .
Should be a easy fix for the new dealer i will try monday morning..

I love my jeep very much and this seems like the last issue to resolve on warranty.It just takes patience.

Problems fixed since new:

Gas filler neck def. Hard to get pump inside and fill up, then started to rattle badly going over bumps.They replaced the black rign collar and still loose so they put foam behind the rign and now everything is perfect.

A bit of water inside trunk after washing by hand since new ,i taught it was normal because its a jeep,but after they adjusted my tail gate latch to fix a knocking noise going over bumps this resolved the noise issue and no more water comming in the trunk after i wash it by hand.

So after resolving the water issue, this jeep will be a 100%.

Still no rain here in SoFlo for the third night in a row since the fix, that is equivalent to a drought here. lol

I'll take a pic or two this morning to see what it looks like, when the coffee kicks in.

Went to new dealer this morning to check water leak.
At 08:50 am dealer said he would put jeep under the shower for test.
At 09:20 am nobody took my jeep in to test even if i had an appointment
So i asked for my key and left.

Went back to dealer where i bought the jeep and spoke with service manager,
left the jeep for a week so they can settle the matter with FCA.
They have about 20 jeeps with these intermittent water leaks on passenger floor.
FCA does not want to pay dealer more money to fix water troubles and dealer knows it is a design flaw .
Now waiting to see what happens.
Many customers are fed up and want them to fix this issue or give us our money back.
To follow.....
