Back with another couple of updates in my quest to keep this thread alive.
Update 1: Battery died at 92,000 KM and 2 years of use. Felt that the car was taking marginally longer to start up and that the retractable mirrors were also slow to open. Immediately took the car to a nearby battery shop and got a new one. For all those wondering, the OE battery is a Daewoo DIN-666. Cost me 17k after trading in the old one.
Update 2: Got a call from Hyundai Premium Motors about an ongoing campaign regarding the inspection of headlights for moisture and installation of moisture absorbing silicate pouches. Went and got it done. Took about 2.5 hours. The lights were taken out, visually inspected for any gaps, the seams were covered in a thin layer of loctite and the moisture absorbing pouches were placed in the slot.
Over the last 2 years, I've never run into any moisture issues with my lights and I mentioned the same to the dealership but they still insisted I get it done while the campaign is going on.
