One rear ABS sensor go mad. Though it was supposed to be just a subsystem, the most of electric features turned off, including power steering, blind spot system, traction, stability controls, cruise control, etc..
When delivered, the car exhibited a strong pulsating feeling in the brakes. The dealer's service department determined that the rotors were rusted in spots and resurfaced them. Problem appears to have been resolved.
After only 2,400 miles on the vehicle a vibration was noticed upon braking. Diagnosed as a warped rotor. Dealer replaced both front rotors and pads under warranty.
The brakes intermittently became very soft and did not stop the vehicle. The dealer replaced the HECU under specially requested warranty extension. This is related to the recall campaign by Hyundai.
Brake pads needed to be replaced and snow tires put on. Dealer wanted $900.00 , outrageous.!!! Went to my mechanic bought the pads( front/back) and vented front rotors. Cost for everything was $425.00 including installation of snow tires.
Complete loss of brakes. Diagnosis is bad abs module likely caused by corrosion issue tied to bad brake fluid. This was a recall (brake fluid). Dealer diagnosed replacement of abs module. Dealer advocated for me, got Hyundai to cover the $3k repair.
