This issue has caused some much wasted time and frustration. I own a 2017 Sante Fe Sport, and even after being into the dealership 3 times for service, the problem is still persisting. The first two times, they used a product that is sprayed into the system and then heat/etc is run in intervals to dryout the system. The last time, they SUPPOSEDLY replaced the entire air compressor and cleaned it all out. Well, the smell is returning. If they did ACTUALLY do what they said they did, there is most definitely a design flaw that Hyundai is hiding. I would be interested in finding out more.Same problem in my 2010 Elantra with 85,000 miles. It actually makes me cough as soon as I inhale the odor. I've had 4 brand new cars for 10 years each and none had this problem. My friend's Camry has more miles than my car and his a/c is still as fresh as a morning breeze. My Mom's 1999 Sentra has 160,000 miles and has never had this problem - and she lives in Florida where they use a/c 12 months a year!
Is there a design flaw that causes this? Is a class action or recall under consideration by anyone?
