#68 of 91 Jeep Liberty Engine Light, Rough Idle, Poor Shifting, Poor Gas Mileage
May 29, 2011 (9:47 am)
Does your Jeep Liberty have the above referenced problems? My girlfriend has been having a recurring problem with her JL 2003 for at least the past 5 years. She has struggled with a recurring check engine light. Every time she has brought it in to a shop, they discover that the problem is a poor sealing gas cap. Today I decided to actually do some investigation of my own.
The first thing I did was look at the gas cap compartment. I noticed that it was filled entirely with a persistent film of black, sooty residue. This is not normal. I then removed the gas cap and inspected it closely. Upon inspection of the underside of the cap (the white part that screws in), I noticed more black soot all around the upper seal mechanism, but mostly in two locations. I also noticed that the bottom-most seal had a spring-loaded pintle that is meant to act as a pressure-relief valve should the internal gas tank pressure go above the spring pressure. HOWEVER, THIS PINTLE APPEARED TO BE INSTALLED UPSIDE DOWN AS IT NEVER SEEMED TO SEAL AT ALL!
So I disassembled the entire gas cap. I cleaned all the parts with carb cleaner, and reassembled the cap components the way that I thought they should go together. I then re-installed the gas cap... and voila'. The car is now a joy to drive. The hesitation - gone! The poor shifting - gone! The rough idle - gone!
IT APPEARS THAT WHOEVER ASSEMBLED THE GAS CAPS FOR JEEP (AT LEAST FOR CERTAIN MODEL YEARS) ACTUALLY INSTALLED THE INTERNAL LOWER SPRING RETAINER UPSIDE DOWN!
If you have this problem, please bring it up to your Chrysler dealer. They will probably hem and haw and will not believe you, but I guarantee you that if you have been having the problems my girlfriend reported, replacing the cap with a correctly assembled version will solve the problem.
Good luck, as most OEMs are not very good at admitting their mistakes.

#71 of 91 Window problem on driver's side - 2007 Liberty
May 29, 2011 (10:40 am)
Hi I have a 2007 Jeep Liberty -- the window on the driver's side continually gets stuck about 1/2 way up when rolling the window up -- I have to take it down again and then try again and it usually goes up -- it also makes noises when it is getting stuff. Chrysler said -- put a little WD 40 on the edges of the window and all will be fine -- forget it - still gets stuff. Chrysler sent me a notice in Feb that the warranty on the window - drivers side front was getting an extended warranty -- another 2 years, because of problems with the window latch, etc. So, I went to the Chrysler shop and they said -- we have to take the window apart to see if it is the part that Chrysler will fix and replace -- if it is not this part, you pay all costs of looking and fixing!!! I find this unbelievable!~! Is the warranty good or not ? I contacted Chysler in Ontario and they said, too bad - that is our position -- it may not be the faulty window lever or such and you will have to pay all -- I said -- shove it!! Has anyone else experienced this type of poor service from these people ? You can rest assured, we have purchased our last Chrysler product and I will do my best to let others know just how good the warranty really is and how dishonest this company is -- don't buy Chrysler- they cannot be trusted and their word is not good -- they are all smoke and mirrors and really do not care about the consumer. Anyone else have this problem with these guys. Thanks. Zeta

Manual? After a year of thinking we didnt have one, we found out that there is a slot just above the inside of our glovebox.

#74 of 91 ck engine light
Jul 03, 2011 (7:39 pm)
I just recently purchased my 03 JL and everything is all right with it, except for the ck engine light that just came on today...I just purchased a locking gas cap for it. Checked that the gas cap was on correctly and tight, but ck engine light is still on. I bought the gas cap two days ago and the light wasn't on yesterday or this morning. But when I left work it went on and I ck'd everything I know (like the gas cap) and it still is on... what can it be?

I had the exact same thing happen to me today in my Liberty -- and I am looking for an answer to the mystery! I read my owner's manual cover to cover but couldn't find any information about what the bell sounds indicated. Have you gotten the answer yet? If so, please do share! Thanks!

#77 of 91 ABS ESP & BAS & traction control lights keep coming on
Nov 08, 2011 (6:45 am)
I have an 07 Jeep Liberty 4 x 4, 6 cyl...approximately $53K mi on it...at $49K miles...I am just driving down the interstate, in 80 degree weather, dry conditions, and hear the warning light tone (& I wasn't low on gas this time!)...& all 3 of these lights were on....when I got to where I was going & turned the engine off and back on they did not come on...this had happened once several months ago also, when I had started up my vehicle to warm up the vehicle....same thing, I turn off the engine & back on & they go off. This has happened twice again this past week...once while driving, & once on the cold start....I keep reading things about this but not sure if I need to have it looked at...I am seeing a lot comments where no problem is ever found when these come on....I am not getting any warning lights that illuminate for the 4wd system...
