The brake rotors are faulty and become warped at 9k mile I now have 27k and are extremely warped causing braking issues at higher speeds. I have been waiting over two months for new rotors from the dealer with no word as to when they will arrive. If the vehicle is left un-driven for a couple days the rotors will become rusted. Even the brand new vehicles in the Hyundia showroom are covered in rust. The suspension of the rear shock are extremely weak and bottoms out on the smallest rut. Cornering I’m the vehicle is subject to enormous amounts of whee hop which could result in an accident.
