WATER LEAK ON LOAD FLOOR ON RIGHT OR LET SIDE OR BOTH AT THE LIFTGATE HEADER AND/OR THE LUGGAGE RACK CHANNEL SEAM AREA. *NJ
I have on 09 Liberty and I believe I am having the same problem. I havent had a chance to fully inspect it but i have noticed streaks of water running down my rear window that the wiper is magically missing so it must be inside.
Rear window gasket replaced on the wife's '08 about 3 months ago w/25000 on the clock.
Just noticed the "streak" inside my '09 window. Going in for the annual state inspection next week and will point this out to the service mgr.
I had the same problem here on my '09 and '10 Jeep liberty. Tried replacing seal, cleaned the seal. Can't make the leak go away. I ended up putting some lithium grease on the seal, close the window and never open it again. Just ended up only using the tailgate. Anyways, the lift height is way too high to load any grocery bags or small packages.
The back window leaks a little but isn't a problem. The moon roof leaks a little too when I go thru one of those brushless car washes. Only comes in when the water is spraying directly on the window.
I'm not sure how the water is drained from a Liberty sunroof but if it's like most, there is a "pan" around the perimeter that has some sort of drain to carry water away. Check to see the drains are not partially blocked and not eliminating water quickly enough. No sunroof should leak in a car wash.
I noticed a few dribbles last night on the inside of my rear window of my '10. We had a lot of rain last night--not hard, but constant. I opened the window and shut it, and the leak seemed to have stopped. Hopefully it was a fluke.
I Leased a 2010 Liberty, two weeks in the back window leaked. I took it to the dealer. They CLAIMED they replaced the entire back end. The next rain - MORE LEAKS. Dealer took the Jeep again (one week later) and said I was crazy. I just brought the danged thing back again to be fixed. I have owned the Jeep since Jan 28 2010. For whatever reason Metro cannot seem to repair the window leak. RI Lemon Law dictates after 4 attempts Jeep/Chrysler has to replace the vehicle. I am hoping they have to, I will pick another Chrysler product - its apparent Jeep has an inherent defect in the rear window. I really loved Jeeps but now I see (from this forum) there are nothing but hassels owning a Jeep. The funny thing is, the dealer thinks they fooled me, thinks I fell for it when they claimed they replaced the whole back gate. The proof they did not is in the pudding - the window still leaks! WHY BOTHER TO LIE?????? Shaking my head.
As long as my leak is just a few drops here and there...no biggie to me. I won't try to use the Lemon Law to get them to take back the vehicle...not that big of a deal to me. It's supposed to rain Sunday so I'll check to see if the leak has 100% been repaired.
