DRL occasionally not turning off

[Aramis76]

Hi all,

Recently bought a used 2013 with touring and navigation.

In the last two weeks, it's done this twice on me.

I turn the car off and the DRL/Fog lights never turn off. ( i waited 5+ minutes)
I play with the light switch, from Off to Auto to On and back to Off and they stay on.

I have to start the engine and then turn it back off and then they shut off.

Could this be a sticky DRL relay?

I'm in Canada so the DRL were not added, it was born with them, everything seems stock.

I tried looking in the owner's manual, but they say nothing about relays. Since they do turn on, I know I can exclude the fuses.

Thanks for your help!
