Exclamation Water in battery box after rain & car washes...

I ordered a new 2014 Jeep Grand Cherokee Limited 4x4 EcoDiesel on 1/11/2014 and picked it up on 2/28/2014.

I loved it and had no problems with it until the freezing weather started to turn into spring like weather a month later. At that point I was washing the GC about once or twice a week when it wasn't raining.

I started to hear a sloshing sound coming from somewhere on the front passenger seat side area. The only time I really heard it was when I backed out of my parking space and hit the brake with the radio turned down.

I didn't think much of it at the time but noticed it started to sound like more liquid was building up somewhere on the passenger side area and this was right after it had rained hard for several days. The first time I backed up after it finished raining it sounded like I had a gallon of liquid or more sloshing around somewhere so I started doing some jackrabbit starts & stops hitting the brakes to see if I could tell where it was coming from. After a couple of quick start & stops I could see that water had appeared on my passenger floor mat...!

Aha... Now is when I take it to the dealer and show them the water sloshing out from under the front passenger seat which I later learned was where the battery box was located. The dealer pulled one of the 2 drain plugs on the bottom of the battery box floor pan and about a gallon or more came pouring out.

Now, to make a long story shorter and after 5 different visits to the dealer trying to find how the water was getting into the battery box from checking the sunroof drains, a/c evaporator drain and the fresh air intake on the outside cowl panel, they had to pull the entire passenger side seat, carpet and front "FENDER" off and found that where the passenger side front A-pillar joined the rocker panel assembly that "NO" body seam sealer had been applied from the factory build and that was allowing both rain & car wash water to leak in and run underneath the carpet into the battery box...

Now, after 5 weeks of rain and car washes, PROBLEM SOLVED...!

My jeep build date was 1/28/2014 and the dealer told me that other Jeeps built around that time may also have similar problems...

I hope this might help someone from going through all the hassles and headaches that both me and the dealer went through to finally find the problem...

P.S. I totally love my GC now...

Overall they are better. But these are still built by humans who sometimes screw up. There is no way to inspect 100% of the operations without adding significantly to build time and cost.

To the OP ... I'm glad they got that worked out for you.

I have to say that your dealer deserves a lot of credit for going to those lengths to find and fix the problem.

I know that we all would like to think that our dealers would be able to track down this kind of problem and fix it, but I just don't know if I have that much faith.

I had a similar problem in my 14 Overland. Every time it rained, the passenger floor would be wet and the battery compartment. Took it to the dealer and they found that the drain holes were clogged by spray foam insulation.

This is a weird one because most areas like that on the body frame itself which use fillers and body adhesives would be done robotically--much easier, less labor intensive, and more consistent. This is not to say it couldn't happen (obviously) but it's still a weird one...

The first dealer I took it to said I had to of drove through a stream or high water after they checked the sunroof drains and they were working fine even though I told them the most water I drove in was just rain running down the streets & puddles not deeper than 1-2 inches.

I then decided those jerks didn't know what they were talking about so I took it to a dealer that is the oldest jeep dealer in the area (a lot farther away from home) that had the most experienced techs. They found a couple of things they thought might be causing it such as some foam sealant partially blocking some drain holes but not completely closed off.

I know everyone was really upset that they couldn't find the problem as much or more than myself and after the 2nd time of bringing it back in they paid for a rental car so I wouldn't have to pay for it and they could keep it for a few days.

They were great, not giving up and determined to fix the problem...

That's what the dealer finally came to the conclusion of was that one of the robots must of had a problem with applying the seam sealer used in that application.

I read about another guy that had similar problem as mine, but also getting water under the spare tire area which sounds like to me that the whole passenger side of his GC may not of gotten any sealer. His GC might of been the one on the line in front of mine...! LOL

Re: Water in battery box after rain & car washes...

Took a look at my battery today to disconnect before doing some electrical work and I found water in my battery box as well..maybe 1/8" worth. Mine was built March '14. Now I'll have to wait until Monday to see the dealer and get a fix before working on my project

Just wondering - any issues since you have had that dealer fix the problem?
