Car: 2013 Hyundai Santa Fe
Location: Atlanta, GA
Problem: We have a sweet burning smell like antifreeze or oil coming from the vents when the heat is on. We have taken it to 3 mechanics and they can’t figure out what it is. We expect the heater core is going bad, but the symptoms do not fully match what we are experiencing. We do not have any leaking antifreeze, nor do we have any windows fogging. They also ran a pressure test which came back normal.
Any thoughts? Thanks for your help!
