Have a 2004 Santa Fe. Check Eng light came on took it to the Hyundai Dealer in Greenville, Tx. they told me the throttle body needed to be replaced, stated it would be around $1,400.00 it was running rough so I told them to fix it and while it was there to change the oil & filter. when I went to get it the bill was almost $1,800.00 I didn't have my reading glasses with me and I wasn't feeling well so I just paid it and came home. Upon reading the invoice They had replaced the cabin air filter, the engine air filter, the fuel tank air filter which had not been approved. I called the service manager about the unauthorized work. He said he would check into it and call me back. He hasn't and when I call he will not talk to me. The answering service says he is busy & she will give him my name & number .HAVEN'T GOT A CALL YET . Also haven't driven the vehicle 25 miles and the Dam check eng light is on again with code P1193 which said the Limp home valve is detecting a Electronic Throttle System failure. What do I Do ?????

 

Go back to the service manager and complain.
What else can you do?
