Walked around my C6 vert and noticed the front left headlight had small 1/8" in length, more less, stress cracks, lots of them. Swung by the dealer, turned out it will not be covered by warranty (47,000 miles) and to replace it, a little over a grand. But, the thing that got to me was this, GM said chemicals could cause the problem, no problem there, or washing it with soap and water (excess improperly diluted soap). What? soap and water? The right headlight is pristine. Same soap used on both. In addition, the body shop said the damage looked to be coming from the inside, not the outside.

Decided to live with it for awhile at least unless it gets worse. Plan on trading at the end of the year anyway. Next time, a Porsche or BMW? Kidding.

the headlight plastic is crap and gm's response is even crappier. they'll say anything to keep from replacing them. it happens to most c6s, unless they're garage queens i guess.

Probably lucky they still answer the phone now that they are Govt. Motors. At least the right light looks good and my last C6, no problems with the lights on that one at all. I'm assuming then the 2010 will have the same potential problem.

They make a plastic polish the boating stores sell.

It will protect the lens.

I wonder if the polish I use on the windscreen on my bike would work as well?

I had the same issue, and the same response from my dealer; well my dealer said it was caused when an object struck the light! I also tried to polish it out, but since the crazing is on the inside it was a waste of time. I'm installing a new light assembly myself, although it appears to be a rather difficult job for an amateur!

Sorry to hear that dude,GM's Service sucks when it comes to warranty.

Let me know if any of you want to sell your crazed headlights.

Come on, admit it, you know you use a different soap for the other headlight.

Nueboch

Caught!!

Why do you want a crazed headlight?

rdm1465

He actually likes taking them apart and does what he can to fix them. There are posts of him doing this.

BigNastyZO7

same thing happend to me and gm covered it.....both headlights changed free of charge! they will do it but you have to push the issue!!!

I had the same thing and used the TSB to get the dealer to honor a warranty replacement. Thank you forum members for that TSB back in February...saved me $900.00. And why not use glass instead of the lowest bidder plastic? Oh well...

RLSebring

I have heard of a few getting the light(s) replaced under factory warranty but none under extended or no warranty.

Please tell me whaich TSB covered the crazed headlights getting replaced.

Thanks

It happened after the 3/36 warranty period. They don't need to say anything. It's not their problem.

I know the above sounds harsh, but it's true. If the OP were under warranty or had GMPP bumper-to-bumper and GM tried to weasel out, I would agree 100% that it was a lame move, but unless OP states otherwise, that is not the case.

My guess is something hit the headlight. An impact very well might cause cracking from the inside out. If it flexed the plastic, it would flex inward, placing the most stress on the inner portion of the lens.

I promise you that the plastic will take more abuse than glass will. GM would not cover your windshield if you put a rock through it, and it's not their responsibility to. That is yours or your insurance company's. Now, after about the 4th or 5th $600 glass headlight you replaced, what do you think your policy/wallet would be looking like?

Best bet is to have the lights wrapped in Venture shield or something equivalent to mute the impact of any road debris. My lights are done and you can't even tell unless I point it out. Even if you don't do the rest of the front, the lights probably won't run you more than $50-100 installed. Well worth it.

The plastic lens is how much?? Both of mine have a gouge in them. How I have no clue. Was going to replace them.

Snagle

I do not think GM sells the plastic, just full headlight assemblies.

There are forum vendors that will sell you replacement plastic or you can ship them your lights, they will change the plastic and return them to you. This is less expensive than purchasing the complete assembly.

What vendors ? PM me if needed. Thanks.
