One common component that will cause this type of fault here is the Front SAM control module/ecu itself.This ecu controls and monitors the lights and can fail internally electronically causing this issue here needing replaced.I have seen the Front SAM fail before in the past like this here affecting the lights and can keep one or more lights on like this here.If you have not had the fault codes checked to see what codes are set this needs done.Any codes set need diagnosed to locate and repair the fault here.I suspect the SAM will need replaced.
This can cost over $1000 to have replaced and a dealer has to code/program it with their SDS machine before it will operate properly in your vehicle.
