Is it that mark next to the projector lens? If so, take it to the dealer and make a warranty claim. Still got the stock bulbs in I hope?

Hi Kiwi, Did it's happen to you? Hyundai Australia tried to tell me it's not warranty coverage. Cheers,

Looks like burn damage - I wonder if it may be damage due to the sun at an unfortunate angle getting reflected/focussed onto the lens via the inner optics

As @mikeselectricstuff says, I think sunlight reflection seems a possibility, hard to see what else would concentrate so much heat in one spot, especially as it looks to be offset from the headlight beam.

I remember having a whole load of cassette tapes (remember those?) melt after I left them on the dashboard of a car years ago, the sun had somehow been focussed on that area and they got hot enough to melt so all the cases were distorted and stuck together. IIRC, cassette cases were made from polystyrene, that has a transition temperature of around 110°C, so exceeding that on a dashboard is possible. The glass transition temperature of the polycarbonate that the lens is made from is a fair bit higher, around 150°C, but it seems possible that the sun might be able to produce that sort of temperature inside the light unit.

Hi Jeremy, thank you for your opinion I have been living in North queensland Australia but my car always keeps in the shade.I have some time go out and about to town but never leave parking in the open all day and night time parking in my garage since Aug 2019. I am very pleased to hear your comments. Thanks.

Does it affect the beam?

And if Len does that to the other one, ask him why?

Thank you for your reply.

Unfortunately you will be responsible for the repair of the lens.

The L.E.D light bulb will not be affected or affect the material that your lens is made from.

Thank you.
Kind regards,

I think they might be correct in regards 'outside influence', it may be that a random solar reflection has focussed itself off the back reflector. Part of the issue with 'crystal', rather than diffusing, headlight lenses.

You have some super-hot Sun down there, I spent a year in SA and was surprised at how much hotter the Sun felt there than anywhere else I'd experienced (which was probably South California, not exactly known for insufficient sunlight).
