Hi I have 2008 G37 coupe.
My headlights getting fogged a lot recently, especially at the top corner.
I had G35 coupe previously and never had this problem this early.

So I thought it was defect and I took it to the dealership
and they said its the weather/environment concern so they will not do anything and told me to spend $100 to get the restoration service done.

Has anybody has this problem and got away under warranty or something?
at least free restoration service?

Let me know what should I do with my headlights

Thanks

 

That shouldnt happen unless the headlights have been worked on and it wasnt sealed back properly. Did you get some work done to your headlights? changed any bulbs recently?

I think you have a viable case with the dealer if your headlights were unaltered.

 

Ask the dealer to pull this TSB, and go through the procedures:

TSB ITB03-051e
Headlamp fogging issues.

 

well i already told the dealership that was on TSB, but they said its normal wear/tear due to environment hm

 

wait ..the con for changing any bulbs is fogging?

 

Thats not what I meant. Maybe those rubber seals werent put back properly? maybe the light bulb harnesses werent put back properly?

 

the problem that iam having its not a water vapor fogging
its like a scratch looking fogging on the headlight

 

Ohhh! you mean oxidation fogging? Thats not fogging, more like cloudy

If thats it then, yeah, not covered by warranty. Need to get it restored.

There's vids on youtube on how to restore it yourself.

Mine has the same problem.... but I had a shop do mine.

 

I had some light cloudy oxidation forming near the parking shrouds on both of my headlights of my 08 sedan. It was very strange b/c it occured on both lights at the same spots. I took it to my dealer recently and they replaced both headlights no questions asked. I guess I got lucky. FYI I had no other work done on the lights other than Philips Ultinons 6000k + some PIAA led's. The didn't give me any issues though.

 

It canty be all that bad, so you can do it yourself. It's almost like buffing a car. Go buy "Scratch-X" I think. A scratch remover for plastic, it should do the trick.

 

hm so i guess i have to run the restoration process myself
can u give me some details on that?
or is it worth pay $100 and let the dealership[ do it?
thanks

 

(this is what happens to headlights that are never waxed. the sun burns them!)
Depending on the damage, its pretty simple to fix. Here is what you will need:
1. Spray water bottle with distilled water & gentle soap mix. just a few drops of soap is enough.
2. 2000grit sandpaper (pre-soak it in water for 20mins prior to working)
3. polishing compound.
4. wax
5. 2 gentle junk t-shirt pieces

Directions:
1. Windex the whole headlight and let it dry.
2. Spray your soap/water solution and begin to take 2,000grit sandpaper, and gently start sanding away, across the whole headlight, evenly. You will start to feel through the paper how hard your pressing, and how the headlight is becoming smoother & smoother.
3. While sanding, you will develop dust, spray that dust away with the pre-mixed soapy water. (keep the headlight wet, and soapy. it acts like a lubricant, and also removes the dust.
4. once its sanded, and you feel that the headlight is evenly sanded, and really, really smooth- stop. (it will take maybe 1-2minutes of GENTLE, even sanding to remove about 10 years worth of sun-burn.)
5. windex the headlight, and let dry.(you will notice, it looks F-ed up even worse now. it looks unfixable.... but dont worry.(make sure your wife or gf isnt around after this step... i promise the headlight will look F-ED UP, and you'll be in for it!
6. take your polishing compound into a small gentle waxing sponge and start rubbing in circles, adding that same soapy water.(just 1 small spray should be enough per time). the polishing compound you want to keep wet, and rubbing evenly in circle formation for about a good 2-3minutes. then just slow down your circles, and rub it until its dries under your sponge.
7. with a clean cloth, buff out all the polishing compound(the headlight will look much better now)
(if the headlight is still not looking good enough, do the polishing compound process twice now. depending how hard you pushed while sanding, you might need to do this process twice to even the fine scratches out)
8. apply a liberal amount of wax, also in circle formation. and let it dry.
9. with another clean cloth buff out the wax, and your done.
(for best results, and for longer life span of the cleaned up headlight.. do the waxing twice as well. and once every couple months.)
these will be your results:

 

I just tried this out on my cars and it worked great. The headlights look like new. Thanks for the great tips and diy.

 

glad to see everything worked out bro!
