Affected Component: TRAILER HITCHES

Summary
THE 2017 SANTA FE (NC) AND 2016 – 2017 TUCSON (TL) ARE AVAILABLE WITH A GENUINE HYUNDAI TRAILER HITCH AND WIRING HARNESS. ON CERTAIN UNITS, WHEN THE TRAILER’S LIGHTING WIRING HARNESS IS CONNECTED TO THE VEHICLE, THE TOW HITCH MODULE MAY MALFUNCTION RESULTING IN CONTINUOUS ILLUMINATION OF THE TRAILER’S BRAKE AND/OR TURN SIGNAL BULB(S). THIS CONDITION AFFECTS ONLY THE TRAILER’S LIGHTING; NOT THE VEHICLES. IF A VEHICLE EQUIPPED WITH THE GENUINE HYUNDAI ACCESSORY TOW PACKAGE IS DRIVEN WITH A TRAILER, IT IS POSSIBLE THAT THE TRAILER LIGHTS WOULD BE UNABLE TO COMPLY WITH FEDERAL MOTOR VEHICLE SAFETY STANDARDS. A FAILURE TO NOTIFY OTHER VEHICLES OF THE DRIVER’S INTENT COULD POTENTIALLY INCREASE THE RISK OF A CRASH.
