I've had this vehicle in 3 times since August 2011 for an Antifreeze smell coming into cabin. 1st time the dealer sprayed a fragrance on the carpet to cover up the smell even though the mechanic that came to see the vehicle did in fact confirm the smell. We are not losing coolant. The 2nd time they ran it up and down the road. they said they could not duplicate the problem. I suggested they look at the cabin air filter and service adviser said it was a 2 hour job and they would not do it. I contacted Hyundai Headquarters but they failed to get back to me. It is currently back at the dealer and Yes you guessed it. They cannot find any problems.
