air conditioning suddenly stops working. Have to completely turn car off and restart for it to come on again. Funny thing, this also happened on a different Santa Fe that I was test driving. Bringing to dealer today for him to diagnose.
Stay tuned!

UPDATE: Dealer said he called Hyundai. They new exactly what he was talking about. Told me not to run the A/C past 7 (do not use auto) and I would not have a problem. Something to do with the 5 fan speeds. Had to order a part. Will probably be a recall.
