Service bulletin 5NP-D8L3J-01

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's 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.
