One rear light wont turn off

Hello all,

I have been having trouble with my rear lights on my 2015 Cherokee. A few months ago my driver's side rear light would not turn off most (but not all) times I shut off the vehicle. The problem went away for two months. Now, my passenger's side rear light will not turn off. I tried turning the vehicle on and off again, making sure I did not shut it off with the signal on.

Also, the driver's side turn-signal works but the passenger's side does not. The light on the passenger's side stays on constantly.

Anyone have similar problems or have a suggestion?
