Headlight Condensation on 2011 JGC

I just purchased a 2011 JGC 2 days ago. I've notice the front headlights have moisture trapped inside sometimes. Has anyone else seen this? Is it normal?

Any input is greatly appropriated.

Thanks!

Sounds like they might have not been sealed up properly. You should not get condensation build uP in brand new headlights. I'm sure they would replace them under warranty. Atleast I would hope.

I have not seen this on my 2011, but my wife's Audi had it occur on both lights and their service bulletin stated it was a faulty or clogged vent. It's possible it's the same on the Jeep units and you have a vent that was manufactured with a flaw or not installed properly. I have no idea where to look for the vent - sorry.

In any case it's not normal and should be fixed.

^^^ preferably replaced as the sealing occurrs in the actual manufacturing process with special adhesives. Headlights do have small vents but it's not something you can clean or even access. They need to be replaced.

Thanks everyone. I noticed it while I was still at the dealer right after they washed it so I'm thinking its not sealed up, although I cant see anything visible. The service department was closed at that time, so I will bring it back and have them replace.

Thanks again!

Oh, and daleklotz i have it in both headlight as well, so maybe it could be a vent problem. I will have them check that as well.

Hi guys,
Any update on this old topic? Curious because I picked up a 2013 GC Overland and it has condensation in both headlamps. Dealer said it would clear up on its own but it's been a few days and I don't like it. Curious to get your input...

Have you left the lights on for any amount of time? Try leaving your high beams on for a bit. Should dry it up pretty quick then just worry if it comes back again

from the 2013 WK FSM:

STANDARD PROCEDURE - FRONT LAMP UNIT MOISTURE CLEARING
Some customers may report that on occasion, vehicle exterior lamp assemblies are fogged with a light layer of condensation on the inside of the lenses. This may be reported after the lamps have been turned on and brought up to operating temperature, turned off, and then rapidly cooled by cold water (such as rain, or the water from a car wash). Lens fogging can also occur under certain atmospheric conditions after a vehicle has been parked outside overnight (i.e., a warm humid day followed by clear cool night). This will usually clear as atmospheric conditions change to allow the condensation to change back into a vapor. Turning the lamps on will usually accelerate this process.

A lamp that exhibits condensation/fogging should be evaluated in a service bay environment by first drying all water from the outside surface of the lens and operating the lamp for 20 minutes. If the condensation/fogging has begun to clear from the lamp lens after 20 minutes with the lamps operating, this indicates the lamp sealing has not been breached, and the lamp does not need to be replaced.

If the condensation/fogging has not begun to clear after 20 minutes with the lamps operating, or the lamp has large amounts of water droplets visible on most internal surfaces, this indicates a problem with the lamp sealing that has allowed water to enter the lamp. In this instance, the customer is also likely to report that moisture in the lamp is always present and never disappears. A lamp that exhibits internal moisture permanently should be replaced.

Thanks Lee! It has been crappy rainy, foggy, snowy weather since I got the Jeep so I'll wait until the weather clears up and then try running the headlights on for 20 minutes to see if it helps.

UPDATE: The condensation appears to be gone for now. Went away on its own I'm guessing when the weather cleared up or possibly during some long commutes home at night. I'll be keeping an eye on it to make sure it doesn't keep reappearing.

well sorry to bring this back from the dead, but my 2011 overland has this too. been raining bit yesterday, but seriously, why is there moisture in there? arent they sealed?

I fear that this might affect the leveling systems in there, etc. bixenon.

How the hell can a sealed headlamp with silica packets inside fog when it gets cold outside?

What should I do? not under warranty anymore.

2011 jeep grand Cherokee headlamps - Condesation

I just purchases a 2011 overland Summit and this morning both had condensation. I literally watched it occur this morning pin Pittsburgh. Are we suppose to just accept it? It does eventually go away FYI
