Hyundai's 7 Year Warranty is False Adverting!

I bought a 1 year old Hyundai i20 in February 2018, the adverts clearly stated that the warranty was 7 years. Hyundai prides itself and uses the 7 year warranty as a sales tactic. This weekend I had did my 90 000 km service at a Hyundai dealership, upon inspection of the vehicle, i had pointed out to the service advisor that I had noticed rust( on a 5 year old car) and that the paint was peeling in certain areas. I was later informed that the 7 year warranty comprises of a year warranty on the vehicle itself and the balance of the two years only covers the powertrain. Therefore the body is no longer covered. This was never brought to my attention, not during purchasing my vehicle nor at anytime after. This is false advertising by Hyundai. I have informed everyone I know that drives a Hyundai to follow up with the warranty.
