Condensation in tail lights or headlights?
 

Yep, that's what happened to mine. Anyone got solutions?

I got the best solution.. use the warranty that came with your new car.

the dealer will replace the lights with brand new ones.

that means you have a leak or a crack somewhere in the seal or your light fixture...

Thanks, didn't know that a leak/crack caused it.

^ just found some condensation in both of my rear tails this past weekend.

+1......

Not necessarily..These light are not really "sealed" despite the fact that they're glued together, there are lots of ways air gets in. Change in atmosphere, humidity etc. especially at this time of year where there are big temp swings from day to night, will easily cause condensation inside the lens depending on where you park at night..It'll disappear after the temps equalize..

I would seriously doubt Nissan would allow these to be replaced under warranty...

might as well try and see if they will replace

I have the same problem, please keep us posted with what you find out at the Dealer.

A voice of reason in a sea of BS.

+1 for you :tup:

yep, wat he said. some water inside is normal unless it starts fogging up real bad.

Im sorry but I absolutely disagree. The lights are sealed.. not 100% waterproof, but pretty darn close to it. Very water resistant especially to the elements.

In the 20+ vehicles I have ever owned, only ONE had a single light that fogged. (jeep grand cherokee) it was replaced by the dealer immediately. These lights are hundreds of dollars and very important "safety"equipment with LED's etc... they are supposed to seal out rain and moisture, not condensate and fog up.. I would take it in.

Can you imagine buying a new GT-R and because it goes from hot to cold, you get a fogged taillight / headlight?? i dont think so.



you have a bad seal somewhere in your rear taillamp and moisture is leaking in.

Just take it in and report back, and then we can all see what really happens.

This occurred after I washed my car. I'll try to post pics of before/after.

which equals a minor leak.

Im sure its not condensation like others said.. unless it was 30 degrees outside and you washed your car with boiling water.



Sorry, i just get a little aggrevated when people call a different theory a "sea of bull$h1t". :shakes head:

...you're scaring me, dudes...I own an '04.5 350Z, and, so far, none of that has occurred, but you got me thinking here; it seems to be happening to quite a few 370s. Has anyone heard of it happening to 350s?!

I have it too on mine its not so bad. But I will give it a few more days before getting it checked out. I just noticed it yesterday.

never seen it on my G37 and weather goes from +40 degrees C to -40 degree C in southern Quebec

happened to my tailights.... i just used silicon and sealed it all the way around... i didnt warranty it cuz... of issues with my dealermodifying my car...... but its fixed now... and it rains crazy here... no moisture ever since...

it happened to my friends 350 but only cuz when he put his hood back on he didnt line it up exactly right and when he would shut the hood it caused the seal the break on the headligt. since he didnt fix it right away he now has a projector bulb out in his drivers headlight lol. then he blacked out the headlights so he has to drive with his high beams at night

Ummm...if there is no moisture, there is no condensation...the reason why you seal something is to totally keep moisture away from it...they don't seal to just glue...think about this, when you have moisture on glass, plastic, mirror, etc, soon after they tend to leave water residue...well, I don't think a manufacturer wants water residue on the INSIDE of covers...cuz in the long run, it may diminish the amount of light through them, and that's another "floormat" recall/lawsuit...

Well......You can't really hermetically seal the lights. Zenons make a lot of heat. There needs to be some leakage to accommodate expansion and contraction from this heat......There are expansion vents on the light. 3 on each tail and I'm sure the headlights have the same since there is more potential heat there. There's always some in and ex-filtration...

I just noticed your sig, is that a cop in the rearview - nice

LOL...No! I actually took the pic from my buddy's Stasis Audi A3 while he did a flyby in my car, and that's a TT in the mirror. We were at a little Audi get-together out at the Tail of the Dragon....Good fun!

Here's a good "cop in the mirror" shot from the year before when I still had the Corvette......:tup:

I thought because of the Xenon they were not 100% sealed because with the amount of heat created they needed to "breath."

Yes...Those expansion vents have a permeable film at the top which allows them to breath. You can blow through them (with some effort)..

The xenons are headlamps only.

The condensation problem with the 370Z is occurring in the Taillights only. So no xenons, only LED's.

We know just the heads are xenon and both the head and tail have the potential to condensate since they are both ventilated. People have reported it in both. The point is They are not sealed. It is perfectly normal.

See "Dew Point info here: http://en.wikipedia.org/wiki/Dew_point

So, sounds like we've established that they aren't 100% airtight.

Anyone have a way to dry them out?

Mine have it too.

just leave it out in the sun.

my G's tailamps are the same from day one. some water gets inside after washing them but it dries up in time.

That generally does it..

In Houston, dew point and humidity are always high and I've never had such problems with my Nissans...I once had a problem with the foglamp of my Acura TL, but that was because there was a small chip in the lens

I just had mine in my tail light on the drivers side. It's in the reverse housing light area. I hope this will go away.

Sumbeotch! 104F to -40F. Remind me to mark Quebec off my retirement places list. :)

sup bro... itll go away but itll keep coming back.... this was the same area as me... i just used silicon to seal up my taillights...

Exact same spot on mine (weird). I noticed after washing it (hand washed). I had condensation in the headlight of my previous car (2006 Charger R/T) and the dealer replaced it.

I might gonna' try going to the dealership first for a replacement instead of repairing it. Thanks for the info though Simota.

o yah bro lol sorry.... jus go to the dealer ship first... the dealer here on my island is dumb... they said it was my fault i didnt wanna argue and put up with there **** so i just solved it myself.... they thought i opened up my tailights cuz it was smoked out on the reverse lamp part....?!? wtf.... anyways ya lol check ur dealer they should warranty it...

yep i got some water in my passenger taililght

I just purchased a new 2010 370z in late December. We had a snow storm and now there is a decent amount of moisture in my drivers taillight assembly. It is in the clear part (for reverse?).

Has anyone had luck with getting dealers to replace? Or is everyone just "living with it"? Is this normal and to be expected?

The owners manual states that this is normal for the headlights, but does not specify for tail lights.
