I have a 2013 3.8 Genesis Sedan with less than 2,000 miles. The brakes started vibrating after 1,000 mile. I brought the car in three times. On this third time the car has been in the shop for two weeks. They tell me they are bringing a second Hyundai engineer in to look at the car. It feels like the rotors are warped but they tell me they replaced them and it did not help. Does anyone have any ideas. I suggested it may be the power hold or the electronic parking brake but got no reaction. The dealership is very nice and they gave me an Elantra as a loaner. What should I do? Just wait? Thanks for your help. gldman
