Hyundai Motor America is recalling model year 2016 Hyundai Tucson vehicles that are equipped with a trailer hitch harness because they fail to comply with federal safety requirements. In the 2,263 affected vehicles, when the vehicle’s engine is running and the brake lights are illuminated, if the turn signal is activated, the trailer turn signal lights will either turn off or remain continuously illuminated (not flash). This could increase the risk of a crash because the driver’s intent to turn would not be clearly communicated to other drivers.
These vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard Number 108, ” Lamps, Reflective Devices, and Associated Equipment.
Hyundai has identified the root cause of the problem to be a potential incompatibility between the tow hitch harness control module and the vehicle’s power supply circuitry. Hyundai will notify owners starting May 6, 2016, and dealers will update the tow hitch harness, free of charge.
